BACKGROUND 
     1. Field 
     The present invention relates to devices, systems and methods for collecting samples of human bodily waste. More specifically, the present invention relates to devices, systems and methods for collecting samples of urine, kidney stones, or stools using a toilet bowl insert. 
     2. Description of the Related Art 
     There are many situations in which samples of human wastes are required for testing. The current state of the art requires a patient to hold a relatively small sample cup closely proximate to the urethral opening and voiding a comparatively small volume into the cup. Such a manual into-the-cup urination collection method can prove to be quite difficult for many individuals, including, but not limited to: those with impaired manual dexterity who are unable to grasp a sample cup appropriately; those with weakness who may be unable to grasp a sample cup appropriately; those with nervous disorders causing manual shaking; those who are morbidly obese and unable to access the anatomical regions necessary to take a urine sample; those who are pregnant and have difficulty with movement; those with bladder control issues or incontinence who may not be able to appropriately start and stop a stream of urine; those who are elderly; those who are very young; those who are partially or totally physically incapacitated; and those who are partially or totally mentally incapacitated. As has been illustrated and will be understood, the collection of waste samples can be a particular trying, embarrassing, and degrading experience for many people. 
     Accordingly, there is a need for improved devices, systems and methods for collecting human bodily waste samples. 
     SUMMARY 
     In accordance with one embodiment, a sample collection system for urine, stool or kidney stone samples is provided. The system comprises a monolithic sample collection body and a sample cup. The monolithic sample collection body has a circumferential rim and a collection bowl that extends downwardly from the rim and is configured for placement on a toilet such that the rim is positioned on the toilet rim and the collection bowl extends into a portion of the toilet. Additionally, the collection body includes a collector port extending from the bottom of the collection bowl. The sample cup is releasably coupleable to the collector port of the sample collection body such that a collection volume of the sample cup is in communication with the collection bowl. The sample collection body is configured to receive a urine, stool or kidney stone sample from a user and direct it to the collection volume in the sample cup via the collection bowl. 
     In accordance with another embodiment, a sample collection system for urine, stool, or kidney stone samples is provided. The system comprises a semi-rigid sample collection body and a sample cup. The semi-rigid sample collection body has a circumferential rim and a collection bowl extending downward from the rim, and is configured for placement on a toilet. During use, the rim of the collection bowl is held between the toilet rim and the toilet seat, such that the collection bowl extends into the toilet bowl. The collection body has one or more drainage troughs, and a collector port which is in communication with the one or more drainage troughs. The sample cup is configured to be releasably coupleable to the collector port such that a collection volume of the sample cup is in communication with the collection bowl. The sample collection body is configured to receive a urine, stool or kidney stone sample from a user and direct it to the collection volume in the sample cup via the collection bowl while only touching the rim of the toilet. 
     In accordance with another embodiment, a kit for use with an interior of a toilet bowl to collect a urine, stool, or kidney stone sample is provided. The kit includes a monolithic sample collection body, a sample cup, and a collection basket. The sample collection body has a circumferential rim and a curved collection bowl extending down from the rim to a collector port which extends from the collection body at an acute angle relative to a plane defined by the rim. The sample cup is releasably coupleable to the collector port and a collection volume of the sample cup is in communication with the collection bowl. The collection basket is removably insertable into the sample cup and includes a basket with a screen configured to allow a liquid to flow through while substantially disallowing passage of solid material therethrough.

     DETAILED DESCRIPTION 
       FIG. 1  illustrates an exploded view of one embodiment of a sample collection device  100 . The embodiment of a sample collection device  100  can include a collection bowl  110 , a sample cup  120 , a collection basket  130 , a screen  140 , and a collector port  150 . 
     In operation according to one embodiment, the screen  140  can be inserted into the collection basket  130  to form a collection basket  130  with a screen  140  lining. The collection basket  130  can then be inserted into the sample cup  120  which has a coupling mechanism at its upper end. In further operation, the combination of the screen  140 , collection basket  130 , and sample cup  120  can be coupled to the collection bowl  110  via the collector port  150  which also has a coupling mechanism. In another embodiment, the collection basket  130  and screen  140  can be a single piece (e.g., monolithic). In still another embodiment, the basket  130  and screen  140  can be excluded and the sample cup  120  can be coupled to the collector port  150 . 
       FIG. 2  illustrates an embodiment of the sample collection device  100  in use on a toilet. In operation according to one embodiment, the sample collection device  100  can be assembled as described with reference to  FIG. 1 : the screen  140  can be inserted into the collection basket  130  which can be inserted into the sample cup  120  which can be removably coupled to the collector port  150  of the collection bowl  110 . In further operation, a user may lift the toilet seat ring  215  of a toilet  201  and place the sample collection device  100  onto the toilet rim  205  of the toilet  201 . In one embodiment, the sample collection device  100  can be dimensioned such that the sample collection device  100  substantially only touches (e.g., only touches) the toilet  201  at the toilet rim  205  of the toilet  201 . By extension, in one embodiment the sample collection device  100  can be dimensioned such that the sample collection device  100  never touches the toilet bowl  210  of the toilet  201 , as shown in  FIG. 2 . In still another embodiment, the sample collection device  100  can be dimensioned such that at least the sample cup assembly of the sample collection device  100  does not touch the toilet  201  (or water in the toilet). In further operation in accordance with one embodiment, the user can then put the toilet seat ring  215  of the toilet  201  down over the sample collection device  100 . In another embodiment, the user can leave the toilet seat  215  up and simply sit down onto the sample collection device  100 . The user may then void waste, including liquid wastes (i.e., urine), solid wastes (i.e., fecal matter), or kidney stones (e.g., via their urine) into the sample collection device  100 . In continued operation, the waste matter can then be collected by the sample cup  120  of the sample collection device  100 . After all desired waste has been collected, the toilet seat ring  215  of the toilet  201  can be lifted (i.e., where the toilet seat  215  was previously lowered over the rim of the sample collection device  100 ), the sample collection device  100  can be lifted out of the toilet bowl (e.g., pivoted about the distal edge of the sample collection device  100  to transfer any overflow of sample from the collection bowl  110  into the toilet bowl), and the sample cup  120  can be cleanly de-coupled from the collector port  150  of the collection bowl  110  and capped and labeled. In final operation, the collection bowl  110  can be disposed of (e.g., placed in a waste bin). 
     In some embodiments, the sample collection device  100  can be sized to seat into and be used with a standard sized elongated toilet bowl  210 . In the United States, elongated toilet bowls  210  are used in substantially all, if not all, commercial, non-residential applications. The dimensions of an elongated toilet bowl  210  are standardized across the United States toilet  201  industry. In other embodiments, the sample collection device  100  can be sized to seat into and be used with a standard sized round toilet bowl  210 . In the United States, round toilet bowls  210  are used primarily in residential applications. The dimensions of a round toilet bowl  210  are also standardized across the United States toilet  201  industry. In yet other embodiments, it will be understood that the sample collection device  100  can be sized to seat into and be used with a toilet bowl  210  of any size. Ultimately, the sample collection device  100  can easily be adapted by one of ordinary skill in the art to seat into and be used with any shape and/or size of toilet bowl  210 , whether it be elongated, round, or even a size not used in the United States. The following descriptions relate to the sample collection device  100  as sized to be used with a standard elongated toilet bowl  210 , but it will be understood that one of skill in the art can modify the dimensions and disclosure herein to adapt the sample collection device  100 , as disclosed, to be used with any shape and/or size of toilet bowl  210 . 
       FIG. 3  illustrates a cross-sectional view of one embodiment of a sample collection device  100 .  FIG. 3  shows the sample collection device  100  fully assembled, as described above. In the illustrated embodiment, the screen  140  is inside the collection basket  130  which is placed inside the sample cup  120  to form a sample cup assembly. The sample cup assembly is coupled to the collection bowl  110  at the collector port  150 . In the embodiment shown in  FIG. 3 , the sample cup  120  is coupled to the collector port  150  by a collector port coupler  160 . The sample collection device  100  as assembled can be used to collect human waste samples. As discussed above, in one embodiment the collection basket  130  and screen  140  can be excluded from the sample cup assembly. 
       FIG. 4  illustrates a side section view of one embodiment of the sample collection device  100 . In particular,  FIG. 4  illustrates the shaping and dimensions of one embodiment of the collection bowl  110 . The sample collection device  100 , can include a collection bowl  110 , a collector port  150 , a collector port coupler  160 , a collection bowl front upper inner radius  410 , a collection bowl front lower inner radius  420 , a collection bowl front lower outer radius  430 , a collection bowl rear outer radius  440 , a collection bowl rim  441 , a collection bowl front outer radius  450 , a sample collection device length  460 , a collection bowl length  470 , a collection bowl depth  480 , a collector seat rim  490 , a collector seat rim thickness  491 , and a collector port angle  499 . 
     Generally, as illustrated in  FIG. 4 , the sample collection device  100  can be a U-shaped insert (see  FIG. 7A ) sized to fit inside a toilet bowl  210  (as shown in  FIG. 2 ). However, in other embodiments, the sample collection device  100  can have other suitable shapes (e.g., round, oval). The sample collection device  100  can have its upper surface defined by a horizontal plane and have a generally bowl shaped depression in its center (a collection bowl  110 ). 
     In some embodiments, the sample collection device  100  can be formed monolithically, meaning that it can be formed out of one continuous piece of material. When formed monolithically, the sample collection device  100  can be formed by using such representative, but not limiting, methods as extrusion molding, injection molding, casting, etc. In some embodiments, the sample collection device  100  can be constructed in separate pieces which can then be coupled (e.g., fused) together. For example, the collection bowl  110 , the collector seat rim  490 , and the collector port  150  can all be made separately then coupled together (e.g., using heat or adhesives, fasteners, etc.). 
     In some embodiments, the sample collection device  100  has a collector seat rim thickness  491 . In some embodiments, the collector seat rim thickness  491  can extend across the entire sample collection device  100  meaning that the entire sample collection device  100  is constructed out of a material having the same thickness. In some embodiments, the collector seat rim thickness  491  can be about 1/16- 3/16 inches thick, including about 2/16 inches thick. However, in other embodiments, the collector seat rim thickness  491  can be smaller or greater than the values above. In some embodiments, the collector seat rim thickness  491  can be slightly thicker than the rest of the sample collection device  100  to advantageously provide a stronger rim for the toilet seat ring  215  to hold, thereby holding the entire sample collection device  100  more securely. 
     In some embodiments, the sample collection device  100  can constructed monolithically out of a plastic, such as but not limited to polyethylene, polypropylene, polystyrene, polyvinyl chloride, polytetrafluoroethylene, and polyamide. In some embodiments, the sample collection device  100  can constructed monolithically out of a metal, such as but not limited to stainless steel or aluminum. In some embodiments, the sample collection device  100  can be constructed out of a composite material, such as by using a fabric or fiber coated with resin. In some embodiments, the sample collection device  100  can be constructed out of any material appropriate for the construction of a waste collection device (e.g., a polymer material, an engineered resin material, a fiberglass material, and a composite material). 
     In some embodiments, the collection bowl  110  can be defined by a collection bowl front outer radius  450 , a collection bowl front upper inner radius  410 , a collection bowl front lower inner radius  420 , a collection bowl front lower outer radius  430 , and a collection bowl rear outer radius  440 . In such embodiments, the side profile of the collection bowl  110  can be defined as follows. 
     The collection bowl  110  surface begins to sink down from the horizontal planar surface of the collector seat rim  490  at a collection bowl front outer radius  450 . The collection bowl front outer radius  450  can be in the range of about 1-5 inches, about 1.5-4.5 inches, about 2-4 inches, and about 2.5-3.5 inches, including about 3 inches or any other radius which sizes the sample collection device  100  to fit within a toilet bowl. To properly fit within a toilet bowl, the sample collection device  100  can be of such dimensions that it advantageously does not come in contact with any inner surface of the toilet bowl  210  or the water held in the toilet bowl  210 . In some embodiments, it is desirable that such contact not occur to inhibit sample contamination (e.g., minimize the chance of sample contamination). In some embodiments, the only contact between the sample collection device  100  (including the coupled sample cup  120 ) is the contact between the collector seat rim  490  and the toilet rim  205 . 
     The collection bowl  110  surface then begins to curve towards the horizontal and forms the collection bowl front upper inner radius  410 . The collection bowl front upper inner radius  410  can be in the range of about 6-18 inches, about 7-17 inches, about 8-16 inches, about 9-15 inches, about 10-14 inches, and about 11-13 inches, including about 12 inches or any other radius which sizes the sample collection device  100  to fit within a toilet bowl  210  as described above. 
     At approximately the bottom surface of the collection bowl  110 , the collection bowl  110  surface forms a collection bowl front lower inner radius  420  before it begins to curve back upwards to meet the rear side of the sample collection device  100 . The collection bowl front lower inner radius  420  can be in the range of about 1.5-5 inches, about 1.7-4.8 inches, about 1.9-4.6 inches, about 2.1-4.4 inches, about 2.3-4.2 inches, about 2.5-4 inches, about 2.7-3.8 inches, about 2.9-3.6 inches, and about 3.1-3.4 inches, including about 3.5 inches or any other radius which sizes the sample collection device  100  to fit within a toilet bowl  210  as described above. 
     At the bottom of the collection bowl  110 , the collection bowl  110  surface bends substantially sharply with a collection bowl front lower outer radius  430  to form the root or base of the collector port  150 . The collector port  150  as formed by the substantially sharp bend of the collection bowl front lower outer radius  430  has a luminal axis (e.g., central axis, symmetrical axis) defined by the circumference of the collector port  150 . In one embodiment, the collector port  150  can be generally cylindrical. However, in other embodiments, the collector port  150  can have other suitable shapes. The luminal axis of the collector port  150  forms an acute angle collector port angle  499  with the horizontal top surface of the sample collection device  100  and is parallel with the collection bowl  110  surface (or collection bowl  110  wall) after the collection bowl front lower outer radius  430 . The collection bowl front lower outer radius  430  can be in the range of about 0.15-0.55 inches, about 0.175-0.525 inches, about 0.2-0.5 inches, about 0.225-0.475 inches, about 0.25-0.45 inches, about 0.275-0.425 inches, about 0.3-0.4 inches, and about 0.325-0.375 inches, including about 0.35 inches or any other radius which sizes the sample collection device  100  to fit within a toilet bowl  210  as described above without touching any of the inner surfaces of the toilet bowl  210  (except, as disclosed above the contact between the collector seat rim  490  and the toilet rim  205 ). 
     After the collector port  150 , the collection bowl  110  surface curves upward toward the rear of the device with a collection bowl rear outer radius  440 . The collection bowl rear outer radius  440  can be in the range of about 1-5 inches, about 1.5-4 inches, and about 2-3 inches, including about 2.5 inches or any other radius which sizes the sample collection device  100  to fit within a toilet bowl  210  as described above. 
     The collection bowl  110  surface joins with the collector seat rim  490  at the rear of the sample collection device  100  and merges from a curved surface to a surface defined by a horizontal plane which can sit, during operation, on the toilet rim  205 . 
     The collection bowl  110  as defined by the horizontal plane of collector seat rim  490 , the collection bowl front outer radius  450 , the collection bowl front upper inner radius  410 , the collection bowl front lower inner radius  420 , the collection bowl front lower outer radius  430 , and the collection bowl rear outer radius  440  has a collection bowl depth  480  (the distance from the horizontal plane of the collector seat rim  490  to the bottom of the collection bowl  110 ). In some embodiments, the collection bowl depth  480  can have a depth of about 2-7 inches, about 2.5-7.25 inches, about 3-6.5 inches, about 3.5-5.75 inches, and about 4-5 inches, including about 4 inches or any other depth which sizes the sample collection device  100  to fit within a toilet bowl  210  as described above. 
     As disclosed above, the collector port  150  has a luminal axis (e.g., a central axis, or axis of symmetry). In some embodiments, the luminal axis of the collector port  150  of the sample collection device  100  can be critically important to the optimal functioning of the sample collection device  100 . As discussed above, some users of the sample collection device  100  can be incontinent, or have bladder control issues. Therefore, in some embodiments, a user may void the entire contents of their bladder into the sample collection device  100  (and as will be apparent, the entire contents of a human bladder can be of a significantly larger volume than the volume of the sample cup  120 ). In these embodiments, it can be useful for the device to allow the user to easily, cleanly and quickly automatically level the volume in the sample cup  120  to an appropriate, hygienic level. In some embodiments, after the user has voided into the sample collection device  100  a volume greater than the volume of the sample cup  120 , the user can level the urine volume contained by the sample cup  120  using the following steps. 
     The user can void any physiological volume of urine into the sample collection device  100 , even overfilling the sample cup  120  (e.g., such that at least some of the urine rests in the volume of the collection bowl  110 ). After potentially overfilling the sample cup  120  with a sample of urine, the user can pick the device up by the front of the device (e.g., lift the front of the device  100  so that it pivots about its distal edge). As will be apparent by observation of  FIG. 4 , when the device is held generally vertically (e.g., about 70°, about 80°, about 90°), for example so that the plane defined by the rim  290  is parallel to the force of gravity, the luminal axis of the collector port  150  holds the sample cup  120  at a fixed collector port angle  499  causing at least a portion of the volume contained in the sample collection device  100  and the sample cup  120  to flow out the rear of the sample collection device  100 . As is apparent to one of ordinary skill in the art, the collector port angle  499  is inversely proportional to the volume which will remain in the sample cup  120  after holding the sample collection device  100  vertically. The greater the collector port angle  499 , the lower is the volume which can remain in the sample cup  120  after holding the sample collection device  100  vertically (with a limit at 90° where the entire contents of the sample cup  120  will exit the sample cup  120  upon holding the sample collection device  100  vertically). As an obvious corollary, the smaller the collector port angle  499 , the larger is the volume which can remain in the sample cup  120  after holding the sample collection device  100  vertically. The collector port angle  499  can be in the range of about 10-80°, about 15-75°, about 20-70°, about 25-65°, about 30-60°, about 35-55°, and about 40-50°, including about 45° or any other collector port angle  499  which both sizes the sample collection device  100  to fit within a toilet bowl  210  as described above and positions the collector port  150  to hold the sample cup  120  at an angle appropriate to allow only a portion of the sample cup  120  to be filled with a sample after holding the sample collection device  100  generally vertically (e.g., about 70°, about 80°, about 90°). 
     The sample collection device  100  has a sample collection device length  460  which can be defined as the length of the sample collection device  100  from the front edge of the device to the back edge of the device. In some embodiments, the sample collection device length  460  can be in the range of about 16-20 inches, about 16.5-19.5 inches, about 17-19 inches, and about 17.5-18.5 inches, including about 18 inches or any other sample collection device length  460  which sizes the sample collection device  100  to fit within a toilet bowl  210  as described above. 
     In some embodiments, the collection bowl front outer radius  450  and collection bowl rear outer radius  440  define the front and back of the collection bowl rim  441 . The collection bowl rim  441  can be an approximation of the upper edge of the collection bowl  110  as it is the apex of the curves which drop down from the collector seat rim  490  (including but not limited to the apexes of the collection bowl front outer radius  450  and the collection bowl rear outer radius  440 ). The collection bowl rim  441  has, or defines, a collection bowl length  470 . In some embodiments, the collection bowl length  470  is just smaller than the length from front to back of a toilet rim  205 . In some embodiments, the collection bowl length  470  can be about 8-14 inches, about 8.5-13.5 inches, about 9-13 inches, about 9.5-12.5 inches, about 10-12 inches, and 10.5-11.5 inches, including about 11 inches or any other length which sizes the sample collection device  100  to fit within a toilet bowl  210  as described above. 
       FIG. 5  illustrates a cross sectional view of a lower portion of one embodiment of the sample collection device  100 , specifically the collector port  150 . Also shown in  FIG. 5  are the screen  140 , collection basket  130 , and sample cup  120  coupled to the sample collection device  100  via the collector port  150 . The lower portion of the sample collection device  100  includes a collector port  150 , a collector port coupler  160 , and a collector port flange  510 . Also shown in the figure are the sample cup  120 , collection basket  130 , and screen  140 . 
     In operation, the screen  140  and collection basket  130  can be inserted into the sample cup  120  as desired, then the sample cup  120  can be coupled to the collector port  150  via the collector port coupler  160  to effectively seal the sample cup  120  to the sample collection device  100  to collect the sample of interest. 
     In some embodiments, the collector port coupler  160  of the collector port  150  can be threads that mate with threads on the sample cup  120  (shown in  FIG. 5 ). In other embodiments, the collector port coupler  160  of the collector port  150  can be a pill bottle-style tab and groove structure. In yet other embodiments, the collector port coupler  160  of the collector port  150  can be any other mechanism suitable for releasably coupling the sample cup  120  to the collector port  150  of the collection bowl  110 . 
     In some embodiments, the collector port flange  510  of the collector port  150  can be a stepped flange as illustrated in  FIG. 5 . The stepped collector port flange  510  of  FIG. 5  can serve to act as a stop for the insertion of the sample cup  120  into the collector port  150 . When the sample cup  120  is fully inserted into the collector port  150 , the upper rim of the sample cup  120  can abut the collector port flange  510  sufficiently tightly such that the collector port flange  510  form a substantially fluid-tight seal with the upper rim of the sample cup  120 . The substantially fluid-tight seal created between the collector port flange  510  and the sample cup  120  can advantageously prevent unsanitary sample leakage from the device during use (e.g., leakage between the threads of the collector port  150  and sample cup  120 ). In some embodiments, the collector port flange  510  is an “L” shaped flange that extends over the lip of the sample cup  120  about the circumference of the collector port  150  to advantageously provide a flow path that extends over the rim of the sample cup  120  thereby preventing the possibility of leakage from the collector port  150  when the sample collection device  100  is in use. In still other embodiments, the collector port flange  510  is any structure which creates a flow path down the surface of the collection bowl  110  through the collector port  150  and into the sample cup  120  which prevents leakage from the collector port  150  while the sample collection device  100  is in use. In still another embodiment (not shown), the sample cup  120  can include an internal threaded portion that can threadably couple to an external threaded portion of the collector port  150 , such that the collector port  150  guides a sample into the sample cup  120  during use while inhibiting leakage of sample between the collector port  150  and sample cup  120 . 
       FIG. 6  illustrates a rear view of one embodiment of the sample collection device  100 . In particular,  FIG. 6  illustrates the shaping and dimensions of one embodiment of the sample collection device  100 . The sample collection device  100 , can include a collection bowl  110 , a collector port  150 , a collector port coupler  160 , a collection port diameter  630 , a collector seat rim  490 , a collection bowl side lower inner radius  610 , a collection bowl side upper outer radius  620 , and a sample collection device width  650 . 
     In some embodiments, the collection bowl  110  can be defined by a collection bowl side upper outer radius  620  on each side of the collection bowl  110 , and a collection bowl side lower inner radius  610  on each side of the collection bowl  110 . In some embodiments, the rear profile of the sample collection device  100  can be defined as follows. 
     The collector seat rim  490 , as has been disclosed previously, forms a horizontal planar surface from which the collection bowl  110  extends downward. The collection bowl  110  extends downward from one side at a collection bowl side upper outer radius  620 . The collection bowl side upper outer radius  620  can be in the range of about 1.5-4.25 inches, about 1.75-3.75 inches, about 2-3.25 inches, about 2.25-2.75 inches, including about 2.5 inches or any other radius which sizes the sample collection device  100  to fit within a toilet bowl  210 . In some embodiments, to properly fit within a toilet bowl, the sample collection device  100  can be of such dimensions that it advantageously does not come in contact with any inner surface of the toilet bowl  210  or the water held in the toilet bowl  210 . In some embodiments, it is desirable that such contact not occur to inhibit sample contamination (e.g., minimize the chance of sample contamination). In some embodiments, the only contact between the sample collection device  100  (including the coupled sample cup  120 ) is the contact between the collector seat rim  490  and the toilet rim  205 . Therefore, in the some of the above mentioned embodiments, the collection bowl  110  can extend downward from the collector seat rim  490  just inside the toilet bowl  210  such that the space between the inner wall of the toilet bowl  210  and the outer wall of the collection bowl  110  is minimized. 
     The collection bowl  110  then curves inward at a collection bowl side lower inner radius  610  to form the bottom of the collection bowl  110 . The collection bowl side lower inner radius  610  can be in the range of about 2.5-5.25 inches, about 2.75-4.75 inches, about 3-4.25 inches, about 3.25-3.75 inches, including about 3.5 inches or any other radius which sizes the sample collection device  100  to fit with a toilet bowl  210 . 
     The collection bowl  110  can be symmetric about a front-to-back vertical plane bisecting the center of the collector port  150 . Therefore, in some embodiments, the rear profile of the collection bowl  110  is formed by one collection bowl side upper outer radius  620  and one collection bowl side lower inner radius  610  on each side of the sample collection device  100 . 
     As disclosed above, the collection bowl rim  441  can be defined by the curves which drop from the collector seat rim  490 . Therefore, in the sample collection device  100  of  FIG. 6 , the collection bowl rim  441  is defined by the two collection bowl side upper outer radii  620 . In some embodiments, the collection bowl side-to-side width  640  is just smaller than the width from side to side of a toilet rim  205 . In some of these embodiments, the collection bowl side-to-side width  640  can be in the range of about 5.5-9.5 inches, about 5.75-9.25 inches, about 6-9 inches, about 6.25-8.75 inches, about 6.5-8.5 inches, about 6.75-8.25 inches, about 7-8 inches, and about 7.25-7.75 inches, including about 7.5 inches or any other length which sizes the sample collection device  100  to fit within a toilet bowl  210  as described above. 
     The sample collection device  100  has a sample collection device width  650  which can be defined as the width of the sample collection device  100  from the left side of the device to the right side of the device (or vise versa). In some embodiments, the sample collection device width  650  can be in the range of about 12-18 inches, about 12.5-17-5 inches, about 13-17 inches, about 13.5-16.5 inches, about 14-16 inches, and about 14.5-15.5 inches, including about 15 inches or any other sample collection device width  650  which sizes the sample collection device  100  to fit within a toilet bowl  210  as described above. 
     The collector port  150  has a collection port diameter  630  which, because the collector port  150  is circular, can be defined as the distance from one side of the collector port  150  to the other side of the collector port  150 . In some embodiments, the collection port diameter  630  can be in the range of about 2-3 inches, and about 2.25-2.75 inches, including about 2.5 inches or any other appropriate collection port diameter  630  to allow the releasable coupling of a sample cup  120  to the collector port  150  using the collector port coupler  160 . Urine collection cups in the United States have standardized dimensions. Therefore, such that the sample collection device  100  can be used with such standardized urine collection cups, the collection port diameter  630  can advantageously be sized mate with the threads of a standardized urine collection cup. That is, in some embodiments, the collection port diameter  630  can be about 2.45 inches. 
       FIG. 7A  illustrates a top view of one embodiment of the sample collection device  100 . The sample collection device sample collection device  100  can include collector seat rim  490  which, at a collection bowl rim  441 , dips down into a collection bowl  110 , a U-shaped rim  701 , a sample collection device rear-to-side apex length  710 , a U-shaped rim front three-quarters radius  720 , a U-shaped rim front radius  730 , a U-shaped rim rear three-quarters radius  740 , a sample collection device rear width  750 , an anterior drainage trough  760 , a posterior drainage trough  770 , a collector back  790 , a right rear notch  795 , and a left rear notch  796 . As discussed above, in other embodiments, the sample collection device  100  can have other suitable shapes (e.g., oval, round), and is not limited to being U-shaped. 
     As is illustrated by  FIG. 7A , the U-shaped rim  701  defines the shape of the collector seat rim  490 . The collector seat rim  490  dips down into the collection bowl  110  approximately at the collection bowl rim  441 . The collector port  150  exits the collection bowl  110  at the base of the sample collection device  100  and includes a collector port coupler  160  (as discussed previously). The upper perimeter of the U-shaped rim  701  (in the aforementioned horizontal planar surface) and therefore the collector seat rim  490 , are defined by the following. 
     The back of the sample collection device  100  is a substantially flat line with two notches, right rear notch  795  and left rear notch  796 . The rear of the sample collection device  100  has a sample collection device rear width  750  which can be in the range of about 10.5-14.5 inches, about 10.75-14.25 inches, about 11-14 inches, about 11.25-13.75 inches, about 11.5-13.5 inches, about 11.75-13.25 inches, about 12-13 inches, and about 12.25-12.75 inches, including about 12.5 inches or any other sample collection device rear width  750  which sizes the sample collection device  100  to fit on a toilet rim  205 . 
     The right rear notch  795  and left rear notch  796  are symmetrical across a left to right plane. In operation, the right rear notch  795  and left rear notch  796  provide a bracing point for the base of sample collection device  100  during the generally vertical (e.g., about 70°, about 80°, about 90°) holding as mentioned previously (e.g., during pivoting of the sample collection device  100  about the rear end to empty the contents of the collection bowl  110  into the toilet). The right rear notch  795  and left rear notch  796  allow a user to simply: finish voiding into the sample collection device  100 ; lift the toilet seat ring  215 ; slide the entire sample collection device  100  forward (i.e., toward the user and away from the rear end of the toilet) until the back portion slips into the toilet bowl  210  so that the right rear notch  795  and left rear notch  796  fit over the corners formed by the toilet rim  205 ; pivot the entire sample collection device  100  on the right rear notch  795  and left rear notch  796  until the sample collection device  100  is oriented generally vertically (e.g., about 70°, about 80°, about 90°) on the right rear notch  795  and left rear notch  796 ; allow the excess urine to flow out the back of the device; and remove and cap the sample cup  120  from the collector port  150  and collector port coupler  160 . The right rear notch  795  and left rear notch  796  allow the process to be dramatically simplified in that the user need not actually pick up the device to use it fully, and therefore it is particularly well suited for individuals with motor disabilities or weakness who would be unable to carefully lift the sample collection device  100 .  FIGS. 28-35  illustrate an embodiment of the sample collection device  100  (not showing the sample cup  120 , collection basket  130 , or screen  140 ) which has both a right rear notch  795  and left rear notch  796 .  FIGS. 28 ,  29 ,  30 , and  31  illustrate the right rear notch  795  and left rear notch  796  particularly well. 
     As mentioned previously, the sample collection device  100  can be bilaterally symmetrical from left to right; therefore only one side of the sample collection device  100  will be discussed. It will be recognized that any statement made about one side of the sample collection device  100  can be applied equally to the other side of the sample collection device  100 . The sides of the U-shaped rim  701  extend forward from the rear of the sample collection device  100  (or from the right rear notch  795  or left rear notch  796 ). The side of the U-shaped rim  701  curves out gently at a U-shaped rim rear three-quarters radius  740  until the sample collection device side apex. The U-shaped rim rear three-quarters radius  740  can be in the range of about 25-39 inches, about 26-38 inches, about 27-37 inches, about 28-36 inches, about 29-35 inches, about 30-34 inches, about 31-33 inches, and about 31.5-32.5 inches, including about 32.93 inches or any other radius which sizes the sample collection device  100  to fit on a toilet rim  205 . 
     As mentioned previously, the point at which the U-shaped rim rear three-quarters radius  740  stops curving out gently is the sample collection device rear-to-side apex. The sample collection device rear-to-side apex length  710  (i.e., the length from the rear of the sample collection device  100  to the rear-to-side apex) can be in the range of about 6.5-10.5 inches, about 6.75-10.25 inches, about 7-10 inches, about 7.25-9.75 inches, about 7.5-9.5 inches, about 7.75-9.25 inches, about 8-9 inches, and about 8.25-8.75 inches, including about 8.5 inches or any other length with sizes the sample collection device  100  to fit on a toilet rim  205 . 
     The U-shaped rim  701  then curves from the sample collection device rear-to-side apex to the front of the sample collection device  100  at a U-shaped rim front three-quarters radius  720 . The U-shaped rim front three-quarters radius  720  can be in the range of about 7-13 inches, about 7.5-12.5 inches, about 8-12 inches, about 8.5-11.5 inches, about 9-11 inches, and about 9.5-10.5 inches, including about 10.33 inches or any other radius which sizes the sample collection device  100  to fit on a toilet rim  205 . 
     The U-shaped rim  701  then curves around the front of the sample collection device  100  at a U-shaped rim front radius  730  on its symmetric path back to the rear of the device. The U-shaped rim front radius  730  can be in the range of about 3-7 inches, about 3.25-6.75 inches, about 3.5-6.5 inches, about 3.75-6.25 inches, about 4-6 inches, about 4.25-5.75 inches, about 4.5-5.5 inches, and about 4.75-5.25 inches, including about 5.03 inches or any other radius which sizes the sample collection device  100  to fit on a toilet rim  205 . 
     The sample collection device  100  can include one or more fluid guiding channels, including an anterior drainage trough  760  and/or a posterior drainage trough  770 . The anterior drainage trough  760  can be a slightly inset trough that can travel along the plane of bilateral symmetry from just before the collector port  150  (i.e., toward the anterior side of the collector port  150 ) toward the front of the sample collection device  100 . The posterior drainage trough  770  can be a slightly inset trough that can travel along the plane of bilateral symmetry from just after the collector port  150  (i.e., toward the posterior side of the collector port  150 ) toward the rear of the sample collection device  100 . The anterior drainage trough  760  and posterior drainage trough  770  can allow guidance of fluids into and out of the sample cup  120  to make the process even more hygienic and simple. The length of the anterior drainage trough  760  can be in the range of about 1-12 inches, about 2-10 inches, about 3-8 inches, and about 4-6 inches, including about 5 inches. The width of the anterior drainage trough  760  can be in the range of about 0.25-2 inches, about 0.5-1.5 inches, and about 0.75-1 inches. The depth of the anterior drainage trough  760  can be in the range of about 0.125-0.5 inches, and about 0.25-0.375 inches. The length of the posterior drainage trough  770  can be in the range of about 1-6 inches, about 1.5-5 inches, about 2-4 inches, and about 2.5-3 inches. The width of the posterior drainage trough  770  can be in the range of about 0.25-2 inches, about 0.5-1.5 inches, and about 0.75-1 inches. The depth of the posterior drainage trough  770  can be in the range of about 0.125-0.5 inches, and about 0.25-0.375 inches. In some embodiments, neither the anterior drainage trough  760  nor the posterior drainage trough  770  are included in the collection bowl  110  of the sample collection device  100 —rather, in these embodiments, the inner surface of the collection bowl  110  is smooth and uniformly curved as described above.  FIGS. 28-35  illustrate an embodiment of the sample collection device  100  (without the sample cup  120 , collection basket  130 , or screen  140 ) which has a posterior drainage trough  770 .  FIGS. 28-32  illustrate the posterior drainage trough  770  particularly well. 
       FIG. 7C  illustrates a sample collection device  100  with a first embodiment of a handle  780 . The handle  780  on the sample collection device  100  of  FIG. 7C  can be a substantially rectangular tab extending from the front of the sample collection device  100 . 
     In some embodiments, the handle  780  is substantially a square. In some embodiments, the handle  780  has approximately squared corners. In some embodiments, the handle  780  has rounded corners (as shown in  FIG. 7C ). 
     In some embodiments, the handle  780  is constructed monolithically with the sample collection device  100  (i.e., the handle  780  and sample collection device  100  can be formed out of one continuous piece of material). In some embodiments, the handle  780  can be constructed separately from the sample collection device  100  then attached (e.g., fused) to the sample collection device  100 . For example, the handle  780  can be made separately from the sample collection device  100 , then the handle  780  can be coupled to the sample collection device  100  (e.g., using heat, adhesives, fasteners, etc.). 
     Just as discussed with regards to the sample collection device  100 , in some embodiments, the handle  780  can constructed monolithically out of a plastic, such as but not limited to polyethylene, polypropylene, polystyrene, polyvinyl chloride, polytetrafluoroethylene, and polyamide. In some embodiments, the handle  780  can constructed monolithically out of a metal, such as but not limited to stainless steel or aluminum. In some embodiments, the handle  780  can be constructed out of a composite material, such as by using a fabric or fiber coated with resin. In some embodiments, the handle  780  can be constructed out of any material appropriate for the construction of a waste collection device (e.g., a polymer material, an engineered resin material, a fiberglass material, and a composite material). 
       FIG. 7B  illustrates a side view of the sample collection device  100  with a first embodiment of a handle  780  shown in  FIG. 7C . In some embodiments, the handle  780  extends downward from the horizontal plane defining the top surface of the sample collection device  100 . The extension downward is defined by the handle angle  781  (relative to a plane that defines the rim  490  of the sample collection device  100 ), which can be in the range of about less than 50°, about less than 45°, about less than 40°, about less than 35°, about less than 30°, about less than 25°, about less than 20°, about less than 15°, about less than 10°, and about less than 5°, or any other handle angle  781  which both positions the handle  780  such that in use it does not touch the toilet  201  and allows a user to pick up the device using the handle  780 . The handle  780  illustrated in  FIG. 7B  has a handle angle  781  of about 45°. 
     A handle  780  as illustrated in  FIG. 7B  and  FIG. 7C  can allow a person (e.g., a user) to pick up the device easily without touching the toilet  201  or any portion of the sample collection device  100  which has come in contact with the toilet  201 . 
       FIG. 7E  illustrates a sample collection device  100  with a second embodiment of a handle  780   e .

     In some embodiments, the handle  780   e  includes 3 ridges in the handle finger inserts  786 . In some embodiments, the handle  780   e  includes 4 ridges in the handle finger inserts  786 . In some embodiments, the handle  780   e  includes 5 ridges in the handle finger inserts  786 . 
       FIG. 7D  illustrates a side view of the sample collection device  100  with a second embodiment of a handle  780   e  shown in  FIG. 7E . In some embodiments, the handle  780   e  can extend downward from the horizontal plane defining the top surface of the sample collection device  100 . The extension downward is defined by the handle angle  781   e  (relative to a plane that defines the rim  490  of the sample collection device  100 ), which can be in the range of about less than 50°, about less than 45°, about less than 40°, about less than 35°, about less than 30°, about less than 25°, about less than 20°, about less than 15°, about less than 10°, and about less than 5°, or any other handle angle  781   e  which both positions the handle  780   e  such that in use it does not touch the toilet  201  and allows a user to pick up the device using the handle  780   e . The handle  780  illustrated in  FIG. 7D  (i.e., handle  780   e ) has a handle angle  781   e  of about 20°. 
     A handle  780  as illustrated in  FIG. 7D  and  FIG. 7E  can allow a person (e.g., a user) to pick up the device easily without touching the toilet  201  or any portion of the sample collection device  100  which has come in contact with the toilet  201 . 
       FIG. 7G  illustrates a sample collection device  100  with a third embodiment of a handle  780   g . The handle  780   g  on the sample collection device  100  of  FIG. 7G  can include a post extending from the front of the sample collection device  100  and a curved portion at the end of the post. As shown in  FIG. 7G , the handle  780   g  can resemble a capital “T” with a curved top. 
       FIG. 7F  illustrates a side view of the sample collection device  100  with a third embodiment of a handle  780   g  shown in  FIG. 7G . In some embodiments, the handle  780   g  can extend downward from the horizontal plane defining the top surface of the sample collection device  100 . The extension downward is defined by the handle angle  781   g  (relative to a plane that defines the rim  490  of the sample collection device  100 ), which can be in the range of about less than 50°, about less than 45°, about less than 40°, about less than 35°, about less than 30°, about less than 25°, about less than 20°, about less than 15°, about less than 10°, and about less than 5°, or any other handle angle  781   g  which both positions the handle  780   g  such that in use it does not touch the toilet  201  and allows a user to pick up the device using the handle  780   g . The handle  780  illustrated in  FIG. 7F  (i.e., handle  780   g ) has a handle angle  781   g  of about 25°. 
     A handle  780  as illustrated in  FIG. 7F  and  FIG. 7G  can allow a person (e.g., a user) to pick up the device easily without touching the toilet  201  or any portion of the sample collection device  100  which has come in contact with the toilet  201 .

In some embodiments, the handle  780   k  can have a front to back depth of about 0.5-1 inches, including about 0.75 inches. In other embodiments, the handle  780   k  can have other suitable dimensions, including a width and/or depth that is smaller or greater than these values. 
       FIG. 7J  illustrates a side view of the sample collection device  100  with a fifth embodiment of a handle  780   k  shown in  FIG. 7K . In some embodiments, the handle  780   k  can extend downward from the horizontal plane defining the top surface of the sample collection device  100 . The extension downward is defined by the handle angle  781   k  (relative to a plane that defines the rim  490  of the sample collection device  100 ), which can be in the range of about less than 50°, about less than 45°, about less than 40°, about less than 35°, about less than 30°, about less than 25°, about less than 20°, about less than 15°, about less than 10°, and about less than 5°, or any other handle angle  781   k  which both positions the handle  780   k  such that in use it does not touch the toilet  201  and allows a user to pick up the device using the handle  780   k . The handle  780  illustrated in  FIG. 7J  (i.e., handle  780   k ) has a handle angle  781   k  of about 0°. 
     A handle  780  as illustrated in  FIG. 7J  and  FIG. 7K  can allow a person (e.g., a user) to pick up the device easily without touching the toilet  201  or any portion of the sample collection device  100  which has come in contact with the toilet  201 . 
       FIGS. 8A ,  8 B and  8 C illustrate varying views of one embodiment of a sample cup  120 . The sample cup  120  as illustrated in  FIGS. 8A-8C  can include a collection volume  800 , a cup wall  801 , a cup label  802 , a sample cup mouth  803 , a sample cup base  804 , a cup wall angle  810 , a cup upper diameter  820 , a cup rim inner diameter  830 , a cup rim outer diameter  840 , a cup height  850 , a basket holding rim  860 , a basket holding rim inset depth  870 , a sample cup flange  880 , a sample cup flange depth  882 , a sample cup rim inset depth  883 , a sample cup flange seat  885 , and sample cup threads  890 . The sample cup  120 , simply, is a cup with a cup wall  801  rising from a sample cup base  804  and with sample cup threads  890  encircling a sample cup mouth  803 . 
     In operation, the sample cup  120  can be removably coupled to the collection bowl  110  of the sample collection device  100  using the collector port coupler  160  of the collector port  150 . A user may then fill the sample cup  120  with a sample as discussed above. In further operation, the sample cup  120  can be de-coupled from the collector port coupler  160  of the collector port  150  and a cap applied to store the sample contained within the sample cup  120 . 
       FIG. 8A  illustrates a cross sectional view through the center of one embodiment of the sample cup  120 . Shown in  FIG. 8A  are a collection volume  800 , a cup wall  801 , a sample cup mouth  803 , a sample cup base  804 , a cup wall angle  810 , a cup upper diameter  820 , a cup rim inner diameter  830 , a cup rim outer diameter  840 , a cup height  850 , a basket holding rim  860 , a basket holding rim inset depth  870 , and a sample cup threads  890 . 
     In some embodiments, the sample cup  120  can constructed monolithically out of a plastic, such as but not limited to polyethylene, polypropylene, polystyrene, polyvinyl chloride, polytetrafluoroethylene, and polyamide. In some embodiments, the sample cup  120  can constructed monolithically out of a metal, such as but not limited to stainless steel or aluminum. In some embodiments, the sample cup  120  can be constructed out of a composite material, such as by using a fabric or fiber coated with resin. In other embodiments, the sample cup  120  can be made of other suitable materials (e.g., a polymer material, an engineered resin material, a fiberglass material, and a composite material). 
     In the illustrated embodiment, the cup wall  801  rises up from the sample cup base  804  with an increasing diameter (formed by the cup wall angle  810 ). As shown in  FIG. 8A , the sample cup  120  has a cup wall angle  810 , a cup upper diameter  820 , a cup rim inner diameter  830  and a cup rim outer diameter  840 . The cup wall angle  810  can be in the range of about 5-13° off vertical, about 6-12° off vertical, about 7-11° off vertical, and about 8-10° off vertical, including about 9° off vertical. The cup wall angle  810  causes the diameter of the cup to be greater the higher up the cup wall the diameter is measured. The cup upper diameter  820  can be in the range of about 1.5-2.5 inches, about 1.6-2.4 inches, about 1.7-2.3 inches, about 1.8-2.2 inches, and about 1.9-2.1 inches, including about 1.942 inches or any other diameter which permits the sample cup  120  to couple with the collector port coupler  160 . By comparison, the cup rim inner diameter  830  (which is measured higher up the cup wall  801 ) can be in the range of about 1.9-2.2 inches, including about 2.0-2.1 inches or any other diameter which permits the sample cup  120  to couple with the collector port coupler  160 . 
     The cup rim outer diameter  840  of the sample cup  120  can be substantially the same size as the inner diameter of the collector port coupler  160  thereby allowing the sample cup  120  to removably couple with the collector port coupler  160 . The cup rim outer diameter  840  can be in the range of about 2-3 inches, and about 2.25-2.75 inches, including about 2.11 inches or any other appropriate cup rim outer diameter  840  to allow the releasable coupling of a sample cup  120  to the collector port  150  using the collector port coupler  160 . In another embodiment, as discussed above, the sample cup  120  can couple to the connector port  150  such that the connector port  150  at least partially extends into the sample cup  120  (e.g., the cup rim inner diameter  830  is greater than the collection port diameter  630 ). 
     The cup wall  801  rises up from the sample cup base  804  to a cup height  850 . The cup height  850  can be in the range of about 1.75-3.75 inches, about 2-3.5 inches, about 2.25-3.25 inches, and about 2.5-3 inches including about 2.75 inches or any other cup height  850  which allows the sample collection device  100  to be sizes to fit within a toilet bowl  210  as described above. 
     In some embodiments, the sample cup flange  880  can disrupt the outer vertical surface of the sample cup  120  in a horizontal ring-like fashion. In operation in accordance with some embodiments, the sample cup flange  880  abuts the base of the collector port  150  (as shown in  FIG. 5 ) and the upper rim of the sample cup  120  abuts the collector port flange  510  of  FIG. 5 . Therefore, sample cup rim inset depth  883  is the portion of cup height  850  that can couple with collector port coupler  160 . In some embodiments, the sample cup rim inset depth  883  can be in the range of about 0.3-0.7 inches, about 0.4-0.6 inches, and about 0.5 inches, including about 0.55 inches or any other distance which sizes the sample cup  120  to allow the releasable coupling of sample cup  120  to the collector port  150 . 
     In some embodiments, the sample cup  120  can include a basket holding rim  860  disposed a basket holding rim inset depth  870  from the top of the sample cup  120 . The basket holding rim  860  can hold a collection basket  130  in place (particularly, as will be discussed later, when the collection basket  130  includes a flange around it outer upper edge). In some embodiments, the basket holding rim inset depth  870  can be in the range of about 0.3-0.7 inches, about 0.4-0.6 inches, and about 0.5 inches, including about 0.55 inches or any other distance which sizes the sample cup  120  to allow the seating of the screen  140  within the interior of the sample cup  120 . 
       FIG. 8B  illustrates an enlarged view of the coupling area of one embodiment of the sample cup  120 . The coupling area shown includes sample cup threads  890  which can thread into a threaded collector port coupler  160 . In some embodiments, the coupling element of the sample cup  120  can be threads that mate with threads on the collector port coupler  160  (shown in  FIG. 5 ). In other embodiments, the coupling element of the sample cup  120  can be a pill bottle-style tab and groove structure. In yet other embodiments, the coupling element of the sample cup  120  can be any other mechanism capable of removably coupling the sample cup  120  to the collector port  150  of the collection bowl  110 . 
       FIG. 8C  illustrates a perspective view of one embodiment of the sample cup  120 . Shown in  FIG. 8C  are the cup wall  801  which, in this embodiment, has a cup label  802 , a sample cup flange  880  with a sample cup flange seat  885  where the base of the collector port coupler  160  seats, sample cup threads  890  which mate with the threads of the collector port coupler  160  (in a threaded embodiment), and the collection volume  800 . 
     Sample cups used for medical applications, particularly for waste samples, are broadly standardized across the United States (and other locations as well). Therefore, in some embodiments, the sample cup  120  can have at least the same coupling mechanism as a standardized sample cup to advantageously permit interchangeability of the two. In such embodiments, the many parameters could be varied from the standardized cup, including but not limited to cup height  850 , collection volume  800 , etc. In some embodiments, the sample cup  120  can have the same specifications as the standardized cup. 
       FIGS. 9A ,  9 B, and  9 C illustrate various views of one embodiment of a collection basket  130  with a screen  140 . The collection basket  130  and screen  140  as illustrated in  FIGS. 9A-9C  can include at least one basket slat  901 , a basket bottom  902  a basket rim  903 , a basket rim flange  904 , a basket radius  910 , a basket depth  920 , a basket rim flange width  931 , a basket rim outer radius  940 . 
     In operation, the collection basket  130  and screen  140  can be simply slipped into the sample cup  120  which can, as described above, be removably coupled to the collection bowl  110  of the sample collection device  100  using the collector port coupler  160  of the collector port  150 . A user may then fill the sample cup  120  with a sample as discussed above. In further operation, the collection basket  130  and screen  140  serve to filter the sample, thereby keeping large particulate matter out of the sample. In operation, the collection basket  130  and screen  140  can be used to catch kidney stones. In further operation, the sample cup  120  (with the collection basket  130  and screen  140  inside) can be de-coupled from the collector port coupler  160  of the collector port  150  and a cap applied to store the sample contained within the sample cup  120 . The collection basket  130  and screen  140  can serve to keep the particulate matter separate from the liquid sample. 
       FIG. 9A  illustrates a side view of one embodiment of a collection basket  130  with screen  140  installed. Shown in  FIG. 9A  are at least one basket slat  901 , a basket bottom  902 , a basket rim flange  904 , a basket rim flange width  931 , a basket rim  903 , a side screen port  943 , a basket rim depth  930  and a basket depth  920 . Simply, the collection basket  130  is formed by at least one basket slat  901  rising from the basket bottom  902  connected at their top by a basket rim  903 . 
     In some embodiments, the collection basket  130  can constructed monolithically out of a plastic, such as but not limited to polyethylene, polypropylene, polystyrene, polyvinyl chloride, polytetrafluoroethylene, and polyamide. In some embodiments, the collection basket  130  can constructed monolithically out of a metal, such as but not limited to stainless steel or aluminum. In some embodiments, the collection basket  130  can be constructed out of a composite material, such as by using a fabric or fiber coated with resin. In other embodiments, the collection basket  130  can be made of other suitable materials (e.g., a polymer material, an engineered resin material, a fiberglass material, and a composite material). 
     In some embodiments, the screen  140  can be constructed out of wire (e.g., a fine metallic wire screen). In other embodiments, the screen  140  can be constructed out of fabric or a porous spongy material. In yet other embodiments, the screen  140  can be constructed out of natural fibers, such as but not limited to silk. In some embodiments, the material out of which the screen  140  is constructed can have a small pore size to advantageously trap particulate matter. In some embodiments, the pore size of the screen  140  can be in the range of about 5-500 μm, about 15-450 μm, about 25-400 μm, about 35-350 μm, about 45-300 μm, about 55-250 μm, about 65-200 μm, about 75-150 μm, and about 85-100 μm, including any pore size which causes the screen  140  to catch particulate material in the sample. 
     In some embodiments, the screen  140  can be a solid piece of screen  140  lining the collection basket  130 . In other embodiments, the screen  140  can be discrete pieces of screen  140  only covering the holes in the collection basket  130  (attached or fused to the collection basket  130  around the holes in the collection basket  130 ). In other embodiments, as discussed above the collection basket  130  and screen  140  can be a single piece (e.g., monolithic). In still other embodiments, one or both of the collection basket  130  and screen  140  can be excluded); for example, in some embodiments the collection basket  130  can be excluded and the screen  140  can have a flange that rests on the rim  860  in the sample cup  120 . 
     In some embodiments, the basket bottom  902  can have a radius of about 0.675-1.075 inches, and about 0.775-0.975 inches, including about 0.875 inches or any other radius which sizes the collection basket  130  to fit inside the sample cup  120 . 
     In some embodiments, the collection basket  130  has a basket rim outer radius  940  which can be seated against the basket holding rim  860  of the sample cup  120 . In these embodiments the outer diameter of the basket rim  903  (defined by the basket rim outer radius  940 ) can be substantially equivalent to the inner diameter of the basket holding rim  860  of the sample cup  120 . In some embodiments, the basket rim outer radius  940  can be in the range of about 1.5-2.5 inches, and about 1.75-2.25 inches, including about 2 inches or any other radius which allows the collection basket  130  to seat down into the sample cup  120 . As illustrated in  FIG. 9A , the basket rim flange  904  of the basket rim  903  can seat directly onto the basket holding rim  860  of the sample cup  120  to keep the collection basket  130  in place while in operation within the sample cup  120 . The basket rim flange  904  has a basket rim flange width  931  which can be in the range of about 0.02-0.06 inches, and about 0.03-0.05 inches, including about 0.04 inches or any other width with sizes the basket rim flange  904  to seat onto the basket holding rim  860  of the sample cup  120 . 
     It will be understood by one of ordinary skill in the art that there can be any of a number of possible collection basket  130  and screen  140  designs which can work equally well in this particular situation. The operative function is that the basket rim outer radius  940  seats substantially firmly against the inner portion of the cup wall  801  of the sample cup  120  such that substantially the entire sample flows through the screen  140  so as to catch substantially all existing particulate matter. The collection basket  130  as shown is only one possible embodiment of a collection basket  130  and includes several design features that are not crucial to its function, including the number of basket slat  901 , the shape of the screen  140  ports, etc. Any collection basket  130  which serves to filter substantially all particulate matter from a liquid sample is anticipated by this disclosure. 
       FIGS. 10A and 10B  illustrate various views of one embodiment of a collection cup cap  1000 . The collection cup cap  1000 , as illustrated in  FIG. 10A-10B  can include a cap wall  1040 , a cap top  1041 , cap threads  1010 , and a cup rim inset  1030  formed by a cap inner flange  1020 , and a cap inner diameter  1051 . 
     The collection cup cap  1000  can simply be a cap for the sample cup  120  having cap walls  1040  with a cap top  1041 . The inside surface of the cap wall  1040  can have a coupling element to match the coupling element on the sample cup  120  (therefore, it can be the same coupling element as the collector port coupler  160  of the collector port  150 ).  FIG. 10A  illustrates a collection cup cap  1000  with cap threads  1010  which can mate with the sample cup threads  890  of the sample cup  120 . 
     In some embodiments, there can be a cap inner flange  1020  running in a ring on the inside of the cap top  1041 . The cap inner flange  1020  can create a cup rim inset  1030  which can accept the upper rim of the cup wall  801  of the sample cup  120  to advantageously create a substantially fluid tight seal thereby preventing leakage once the collection cup cap  1000  has been applied to the sample cup  120 . 
     In some embodiments, the collection cup cap  1000  can have a cap inner diameter  1051  that substantially matches the outer diameter of the upper rim of the cup wall  801  of the sample cup  120 . 
     As discussed with respect to the sample cup  120 , collection cup caps used for sample cups in medical applications, particularly for waste samples, are broadly standardized across the United States (and other locations as well). Therefore, in some embodiments, collection cup cap  1000  can have a coupling mechanism which can mate with a standardized sample cup. In some embodiments, the collection cup cap  1000  can have the same specifications as a standardized collection cup cap. 
       FIG. 11  illustrates a one embodiment of a sample spatula  1100 . The sample spatula  1100 , as illustrated in  FIG. 11  can include a spatula blade  1110 , a spatula spine  1111 , and a spatula handle  1115 . The wide, flat spatula blade  1110  is disposed on the end of the spatula handle  1115 . The sample spatula  1100  can have a spatula spine  1111  to advantageously add additional strength to the sample spatula  1100 . 
     In operation, the sample spatula  1100  can be used primarily for stool specimens. Frequently stools can be relatively hard or sticky. Such stools can be difficult to place within the sample cup  120 . Therefore, in operation, the spatula blade  1110  of the sample spatula  1100  can be used to scoop a sample of the stools into the sample cup  120  (e.g., push the stool sample into the sample cup  120  while the sample collection device  100  is sitting on the toilet  201 ). 
     In some embodiments, the sample spatula  1100  can be constructed monolithically out of a plastic, such as but not limited to polyethylene, polypropylene, polystyrene, polyvinyl chloride, polytetrafluoroethylene, and polyamide. In some embodiments, the sample collection device  100  can constructed monolithically out of a metal, such as but not limited to stainless steel or aluminum. 
     In some embodiments, the sample spatula  1100  can include a spatula spine  1111  to advantageously provide additional lateral strength for the user to scoop a sample. In other embodiments, the sample spatula  1100  does not include a spatula spine  1111 . 
     In some embodiments, the spatula blade  1110  can be a flat blade with a flattened edge (as shown in  FIG. 11 ). In other embodiments, the spatula blade  1110  can be a flat blade with a curved edge. In yet other embodiments, the spatula blade  1110  can be a blade of any shape which allows a user to scoop a stool sample and place it within a sample cup  120 . 
     Sample Collection Kit Embodiment 
     In some embodiments, a sample collection kit can be provided to a user. The sample collection kit can comprise a sample collection device  100 , a sample cup  120 , a collection basket  130  and screen  140 , and a sample spatula  1100  (or any combination thereof). In some embodiments, prior to being provided to the user, the individual pieces of the sample collection kit can be appropriately sterilized. Additionally, in accordance with some embodiments, the appropriately sterilized sample collection kit can be hermetically sealed as a single unit, thereby advantageously maintaining the sterilization of the sample collection kit. The user, depending on his or her needs, can then select which components of the kit should be used to collect his or her sample. 
     Method of Use for Urine Samples 
       FIG. 12  illustrates a method of collecting a urine sample using the sample collection device  100  disclosed herein  1200 . 
     First, at step  1210 , a person (e.g., user, medical assistant) assembles the sample collection device  100 . Generally, for a urine sample only the sample cup  120  is necessary along with the collection bowl  110 . Neither the collection basket  130  and screen  140  nor the sample spatula  1100  are necessary for a simple urine sample collection. 
     In some embodiments, the collection basket  130  and screen  140  are used in addition to the sample cup  120  and the collection bowl  110 . In this manner it can be possible to catch kidney stones or solid particulate matter to keep it separated from the urine sample in the sample cup  120 . 
     Next, at step  1215 , a person (e.g., the user) lifts the toilet seat ring  215  of  FIG. 2  of the toilet  201  of  FIG. 2 . Both the lid and the toilet seat ring  215  should be up, leaving the bare toilet rim  205  of the toilet bowl  210  exposed. 
     Next, at step  1220 , a person (e.g., the user) places the assembled sample collection device  100 , in this case the collection bowl  110  coupled with the sample cup  120  (as disclosed with reference to the above figures), on the bare toilet rim  205  of the toilet bowl  210 . 
     Next, at step  1225 , a person (e.g., the user) replaces the toilet seat ring  215  down over the assembled sample collection device  100 . In another embodiment, the user can leave the toilet seat ring  215  up and simply sit on the sample collection device  100 . 
     Next, at step  1230 , the user sits down on the toilet seat ring  215  of the toilet  201  causing significant pressure vertically on the collector seat rim  490  of the sample collection device  100  from the underside of the toilet seat ring  215  of the toilet  201 . The compressive forces created when the user is sitting on the toilet seat ring  215  of the toilet  201  advantageously keep the sample collection device  100  firmly in place, disallowing lateral movement, during use thereby making the user more comfortable with the experience. 
     Next, at step  1235 , the user urinates into the sample collection device  100 . 
     In some embodiments, the user can urinate only a small amount (approximately the amount desired for the sample) into the sample collection device  100 . In other embodiments, particularly those in which the user has incontinence or weak bladder control, the user empties the entire contents of their bladder into the sample collection device  100 . In some embodiments, the sample collection device  100  can be sized to accept a volume corresponding to a full human bladder. In other embodiments, the sample collection device  100  can be sized to accept, for example, twice or three time the volume of a full human bladder. 
     Next, at step  1240 , the user stands up from the toilet  201  and lifts the toilet seat ring  215  of the toilet  201 . 
     Next, at step  1245 , a person (e.g., the user) empties the excess urine from the sample collection device  100 . A person (e.g., the user) slides the entire sample collection device  100  forward (e.g., toward the user) until the back portion slips into the toilet bowl  210  and the right rear notch  795  and left rear notch  796  fit over the corners formed by the toilet rim  205 ; pivot the entire sample collection device  100  on the right rear notch  795  and left rear notch  796  until the sample collection device  100  is resting generally vertically (e.g., about 70°, about 80°, about 90°) on the right rear notch  795  and left rear notch  796 ; allow the excess urine to flow out the back of the device. The right rear notch  795  and left rear notch  796  allow the process to be dramatically simplified in that the user need not actually pick up the device to use it fully, therefore it is particularly well suited for individuals with motor disabilities or weakness who would be unable to carefully lift the sample collection device  100 . 
     Next, at step  1250 , a person (e.g., the user) removes the sample cup  120  from the collection bowl  110 . 
     Next, at step  1255 , a person (e.g., the user) places a cap on the sample cup  120 , thereby producing a finished urine sample ready to be surrendered to a health care professional. 
     Next, at step  1260 , a person (e.g., the user) discards the used sample collection device  100 . 
     Method of Use for Kidney Stone Collection 
       FIG. 13  illustrates a method of collecting kidney stones using the sample collection device  100  disclosed herein  1300 . 
     First, at step  1310 , a person (e.g., user, medical assistant) assembles the sample collection device  100 . Generally, for the collection of kidney stones the user will use the collection basket  130  and screen  140 , sample cup  120  and the collection bowl  110 . It will usually be unnecessary to use the sample spatula  1100  for the collection of kidney stones. 
     Next, at step  1315 , a person (e.g., the user) lifts the toilet seat ring  215  of  FIG. 2  of the toilet  201  of  FIG. 2 . Both the lid and the toilet seat ring  215  should be up, leaving the bare toilet rim  205  of the toilet bowl  210  exposed. 
     Next, at step  1320 , a person (e.g., the user) places the assembled sample collection device  100 , in this case the collection bowl  110  coupled with the sample cup  120  which includes the collection basket  130  and screen  140  (as disclosed with reference to the above figures), on the bare toilet rim  205  of the toilet bowl  210 . 
     Next, at step  1325 , a person (e.g., the user) replaces the toilet seat ring  215  down over the assembled sample collection device  100 . In another embodiment, the user can leave the toilet seat ring  215  up and simply sit on the sample collection device  100 . 
     Next, at step  1330 , the user sits down on the toilet seat ring  215  of the toilet  201  causing significant pressure vertically on the collector seat rim  490  of the sample collection device  100  from the underside of the toilet seat ring  215  of the toilet  201 . The compressive forces created when the user is sitting on the toilet seat ring  215  of the toilet  201  advantageously keep the sample collection device  100  firmly in place during use thereby making the user more comfortable with the experience. 
     Next, at step  1335 , the user urinates into the sample collection device  100 . When collecting kidney stones, the user can advantageously urinate the entirety of their bladder into the sample collection device  100  to obtain all kidney stones and fragments of kidney stones possible. Were the user to urinate only a portion of their bladder into the sample collection device  100 , it is possible if not likely that stones would remain in the bladder or kidneys. 
     Next, at step  1340 , the user stands up from the toilet  201  and lifts the toilet seat ring  215  of the toilet  201 . 
     Next, at step  1345 , a person (e.g., the user) carefully empties the excess urine from the sample collection device  100  to advantageously keep the kidney stones in the collection basket  130 . A person (e.g., the user) slides the entire sample collection device  100  forward until the back portion slips into the toilet bowl  210  until the right rear notch  795  and left rear notch  796  fit over the corners formed by the toilet rim  205 ; pivot the entire sample collection device  100  on the right rear notch  795  and left rear notch  796  until the sample collection device  100  is resting generally vertically (e.g., about 70°, about 80°, about 90°) on the right rear notch  795  and left rear notch  796 ; allow the excess urine to flow out the back of the device. The right rear notch  795  and left rear notch  796  allow the process to be dramatically simplified in that the user need not actually pick up the device to use it fully, therefore it is particularly well suited for individuals with motor disabilities or weakness who would be unable to carefully lift the sample collection device  100 . 
     Next, at step  1350 , a person (e.g., the user) removes the sample cup  120  from the collection bowl  110 . 
     Next, at step  1355 , a person (e.g., the user) places a cap on the sample cup  120 , thereby producing a finished urine sample, as well as any kidney stones that may have been collected, ready to be surrendered to a health care professional. 
     Next, at step  1360 , a person (e.g., the user) discards the used sample collection device  100 . 
     Method of Use for Stool Samples 
       FIG. 14  illustrates a method of collecting a stool sample using the sample collection device  100  disclosed herein  1400 . 
     First, at step  1410 , a person (e.g., user, medical assistant) assembles the sample collection device  100 . Generally, for a stool sample only the sample cup  120  is necessary along with the collection bowl  110  and the sample spatula  1100 . Neither the collection basket  130  not the screen  140  is necessary for a simple stool sample collection. 
     Next, at step  1415 , the user urinates as fully as possible without emptying their bowels. When collecting a stool sample it can be undesirable to contaminate the stools with urine. Therefore, prior to taking a stool sample using the sample collection device  100 , it is advantageous that the user should empty their bladder first so as to not contaminate the sample. 
     Next, at step  1420 , a person (e.g., the user) lifts the toilet seat ring  215  of  FIG. 2  of the toilet  201  of  FIG. 2 . Both the lid and the toilet seat ring  215  should be up, leaving the bare toilet rim  205  of the toilet bowl  210  exposed. 
     Next, at step  1425 , a person (e.g., the user) places the assembled sample collection device  100 , in this case the collection bowl  110  coupled with the sample cup  120  (as disclosed with reference to the above figures), on the bare toilet rim  205  of the toilet bowl  210 . 
     Next, at step  1430 , a person (e.g., the user) replaces the toilet seat ring  215  down over the assembled sample collection device  100 . In another embodiment, the user can leave the toilet seat ring  215  up and simply sit on the sample collection device  100 . 
     Next, at step  1435 , the user sits down on the toilet seat ring  215  of the toilet  201  causing significant pressure vertically on the collector seat rim  490  of the sample collection device  100  from the underside of the toilet seat ring  215  of the toilet  201 . The compressive forces created when the user is sitting on the toilet seat ring  215  of the toilet  201  advantageously keep the sample collection device  100  firmly in place during use thereby making the user more comfortable with the experience. 
     Next, at step  1440 , the user defecates into the sample collection device  100 . 
     In some embodiments, the user can defecate only a small amount (approximately the amount desired for the sample) into the sample collection device  100 . In other embodiments, particularly those in which the user has weak bowl control, the user empties the entire contents of their bowls into the sample collection device  100 . 
     Next, at step  1445 , the user stands up from the toilet  201  and lifts the toilet seat ring  215  of the toilet  201 . 
     Next, at step  1450 , a person (e.g., the user) uses the sample spatula  1100  to ensure that a stool sample is in the sample cup  120 . 
     Next, at step  1455 , a person (e.g., the user) removes the sample cup  120  from the collection bowl  110 . 
     Next, at step  1460 , a person (e.g., the user) places a cap on the sample cup  120 , thereby producing a finished stool sample ready to be surrendered to a health care professional. 
     Next, at step  1465 , a person (e.g., the user) discards the used sample collection device  100  and the used sample spatula  1100 .
