Title: Device and Method for Catching a Biological Specimen

Description:
CROSS-REFERENCE 
     The present application is a continuation-in-part application of U.S. patent application Ser. No. 16/844,457, entitled “Device and Method for Catching a Biological Specimen” and filed on Apr. 9, 2020, which, in turn, claims priority from U.S. Provisional Patent Application No. 62/854,010, of the same title and filed on May 29, 2019, both of which are hereby incorporated by reference in their entirety. 
    
    
     FIELD 
     This invention relates to a device and method for catching a biological specimen removed from an individual. 
     BACKGROUND 
     Biological specimens can be captured during surgical procedures such as laparoscopies and endoscopies. During such procedures, medical personnel will extract a biological specimen from an individual and deposit it in a container for transfer to a laboratory or separate room where further testing and study on the specimen can be performed. 
     Commercially available devices that are placed under suction in order to catch biological specimens typically have vacuum efficiencies below 50%. Lower vacuum performance and efficiency results in wasted energy, lower aspiration forces than expected, and potential challenges during specimen removal. In addition, many prior art devices retain bodily fluid within the device when removing the specimen from the subject. As most specimen catching devices are disposed of once done with a subject, the retained biological waste can build up in the biological waste receptacle, which can lead to contamination and potential leakage when the waste is removed from the waste receptacle. 
     After extracting a biological specimen using currently available commercial devices, medical personnel must deposit it into a container. Presently, during this transfer it is very likely that the specimen will be touched, accidentally or intentionally, and/or manipulated such that the specimen&#39;s integrity is harmed. 
     Therefore, there is a need for a device with improved performance and vacuum efficiency that can maintain a high level of suction during extraction/aspiration of a biological specimen. There is also a need for a device and method that facilitate the transfer of a biological specimen into a standard specimen container that eliminates the risk of contamination during the transfer. Further, there is an additional need for a device that removes the specimen from bodily fluid of the specimen, eliminating residual. Further, there is a need for a device and method that is minimally disruptive to the medical procedure being performed. Finally, there is a need for a device having an internal volume that can be cost-effectively illuminated, on demand, in order to assist with the visualization of the materials captured by the device.

     DETAILED DESCRIPTION 
     The present specification is directed towards multiple embodiments. The following disclosure is provided in order to enable a person having ordinary skill in the art to practice the invention. Language used in this specification should not be interpreted as a general disavowal of any one specific embodiment or used to limit the claims beyond the meaning of the terms used therein. The general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of the invention. Also, the terminology and phraseology used is for the purpose of describing exemplary embodiments and should not be considered limiting. Thus, the present invention is to be accorded the widest scope encompassing numerous alternatives, modifications and equivalents consistent with the principles and features disclosed. For purpose of clarity, details relating to technical material that is known in the technical fields related to the invention have not been described in detail so as not to unnecessarily obscure the present invention. 
     Embodiments of the invention will be described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the invention are shown. This invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. 
     In the description and claims of the application, each of the words “comprise” “include” and “have”, and forms thereof, are not necessarily limited to members in a list with which the words may be associated. It should be noted herein that any feature or component described in association with a specific embodiment may be used and implemented with any other embodiment unless clearly indicated otherwise. 
     The present invention is directed to a biological specimen catching device configured for use during medical sampling procedures. In an exemplary aspect, the biological specimen catching device is configured to be utilized with medical procedures that involve suction. The device can capture removed biological specimens, including, but not limited to, polyps. In an aspect, the medical sampling procedures can include colonoscopies, esophagogastroduodenoscopies, and any procedure in which a healthcare provider desires to retrieve a specimen smaller than the aspiration tube. 
     An embodiment of the device  100  is shown in  FIGS. 1-7 . The device  100  comprises a main chamber  200 , an inlet  300 , an outlet  400 , and a removable filter  500 , and is configured to be used with a medical scope  700  and a suction applying device  800 . In an aspect, the inlet  300  is configured to be connected to a medical scope  700  and the outlet  400  is configured to be connected to a line  800  of the suction applying device (e.g., a vacuum system) (see  FIG. 7 ). When placed under suction, the device  100  allows for the catching of a biological specimen captured using the working channel of a flexible medical scope  700  such as an endoscope or colonoscope. The device  100  is configured to be compatible with standard endoscopes, colonoscopes, and hospital vacuum systems. 
       FIG. 1  illustrates the device  100  with the removable filter  500  assembled with the main chamber  200 . In an aspect, the main chamber  200  comprises an interior portion  210 , an exterior portion  220 , a top portion  230 , a middle portion  240 , a bottom portion  250 , an aperture  290 , an aperture side portion  270 , and a non-aperture side portion  280 . The side portion  270  of the main chamber  200  and the removable filter  500  are curved, providing superior ergonomics and ensuring ease of manipulation by the end user. Ergonomics/workflow are maximized as the removable filter  500  can be very easily observed and removed/detached from the device  100 . 
     In an aspect, the removable filter  500  is configured for a single use, with multiple removable filters  500  being available for use with the chamber  200 . That is, once a specimen has been captured on the removable filter  500 , it can be removed and placed into a specimen container, with a new removable filter  500  placed within the chamber  200  for use during the collection process. In addition, new removable filters  500  can be easily and quickly re-inserted into the aperture  290  of the main chamber  200  to minimize the down time between aspirations, as the removal of a filter  500  leads to the loss of aspiration pressure as suction is applied. Additionally, the dimensions of the removable filter  500  allow the medical professional manipulating the biological specimen to minimize the transfer time to the specimen container, with the removable filter  500 , while retaining the specimen, is configured to be received within the container. 
     In an aspect, the main chamber  200  of the device  100  is made from a transparent material, including, but not limited to, clear plastic. In other aspects, other transparent materials can be utilized. While non-transparent materials can be used, it is preferable to use a transparent material in order to see when a biological sample has entered the main chamber  200  and is trapped on the removable filter  500 , discussed below. The main chamber  200  is tapered/rounded along its edges between the top portion  230  and bottom portion  250 . In an aspect, the top portions  230  and the bottom portions  250  have equal heights to improve the ergonomics of the chamber  200 . In an exemplary aspect, the main chamber includes a middle portion  240  that is tapered/rounded along the aperture side and non-aperture side portions  270 ,  280 . The tapered nature of the side portions  270 ,  280  along the middle portion  240  prevents user injury from the exterior surface  220  while reducing the resistance to flow within the interior portion  210  during aspiration and the likelihood of damage to the specimen during extraction/aspiration. 
     The first and second inlets  300 ,  400  extend from the top portion  230  and the bottom portion  250  of the chamber  200  respectively, as shown in  FIG. 2 . In an aspect, the inlet  300  and the outlet  400  are tubular extensions in communication with the interior portion  210  of the main chamber  200 . The inlet  300  and the outlet  400  provide a continuous pathway from the subject via the endoscopic tool  700  and a suction-applying device  800  through the chamber  200  (see  FIG. 7 ). In an aspect, the inlet  300  and the outlet  400  are identical. In an exemplary aspect, the inlet  300  and outlet  400  measure 12 mm vertically with a diameter of 8.39 mm. While the dimensions of the inlet  300  and outlet  400  can vary from those discussed above, these dimensions allow for free airflow during aspiration and ensure compatibility with standard tubing/connectors. 
     The inlet  300  is oriented on the top portion  230  of the main chamber  200  of the device  100  and the outlet  400  is oriented on the bottom portion  250  of the main chamber  200  of the device  100 . In an aspect, the inlet  300  and outlet  400  are oriented in a diagonal fashion; i.e., not in direct alignment with one another. This orientation allows for maximal viewing of the collected specimen, as well as for maximum visibility of the removable filter  500 . The relative locations of the inlet  300  and outlet  400  also aid in the separation/removal of bodily fluid and bioburden from the biological sample. In an embodiment, the inlet  300  is oriented on the non-aperture side  280  of the main chamber  200  and the outlet  400  is oriented in the middle of the bottom portion  250  of the main chamber  200 . While it is possible for the outlet  400  to be arranged closer to the aperture side  270 , pooling can occur directly under the filter  500 , which makes collection of the specimen more challenging. The alignment of the outlet  400  not directly below the filter  500  and not directly below the inlet  300  minimizes the possibility of fluid pooling within the device  100  and optimizes drainage. In addition, the offset alignment of the inlet  300  and the outlet  400  increase the ergonomics of the device  100 , improving the handling of the device  100  by the clinician. In an aspect, the main chamber  200 , the inlet  300 , and the outlet  400  include an internal taper  310  that prevents the specimen from becoming trapped before reaching the removable filter  500 . 
       FIG. 3  is a side section view of the device  100  showing the removable filter  500  within the main chamber  200  of the device  100 . The removable filter  500  includes a main body  505  and a specimen shelf  510  with a top surface  530  and a bottom surface  540 . The specimen shelf  510  includes pores  550  (see  FIG. 5 ). The main body  505  includes a handle portion  590  for the removable filter  500 . The edges of the handle portion  590  comprise tapered edges/grooves  595  that intersect with corresponding raised edges/grooves  570  of the specimen shelf  510 . In an aspect, the shelf  510  is positioned in the center of the main body  505  of the filter  500 . In such aspects, the raised edges/grooves  570  of the specimen shelf  510  are found surrounding the top surface  530  and bottom surface  540 . By positioning the shelf  510  in the middle of the main body  505 , and also the edges  570  on both sides, the filter  500  can be inserted in two different vertical orientations and still function correctly. That is, the filter  500  is reversible in the vertical orientation, with the filter  500  being able to be inserted with the top surface  530  oriented upwards one way, and the bottom surface  540  being oriented upwards the other way. This increases in the efficiency of replacing the filter  500  as the clinician does not need to be worried about the correct vertical orientation. 
       FIG. 3A  is a section detail of  FIG. 3  showing the corresponding edges of the removable filter  500  and the main chamber  200  of the device. As shown in  FIGS. 3-3A , the tapered edges  595  of the handle portion  590  correspond to matching step/grooves  295  found along the aperture  290  of the main chamber  200  that form a lip/groove feature  350  when the removable filter  500  is inserted into the main chamber  200 . The combination of the tapered edges  595  with the lip  295  of the aperture form a sealed unit when the removable filter  500  is inserted into the main chamber  200  of the device  100  improving the vacuum efficiency by increasing the quality of the seal between the chamber  200  and the removable filter  500 . 
     Referring to  FIGS. 4-5 , the length and width of the specimen shelf  510 , including its curved edges, are configured to match the dimensions of the interior portion  210  of the main chamber  200  along the middle portion  240 , to help form a seal. The raised edge  570  of the specimen shelf  510  extends upwards from the top surface  530  and aids in the retention of the specimen on the specimen shelf  510  after the specimen has been removed from the subject, traveled into the inlet  300 , traveled into the main chamber  200  and is caught/trapped. In addition, the matching dimensions of the interior  210  and the shelf  510 , and the raised edge  570  ensure that the flow of the fluid travels through the pores  550  of the specimen shelf  510 , and not around the shelf  510 . The handle portion  590  is used to disengage the removable filter  500  from the main chamber  200  of the device  100  before the removable filter is deposited into a specimen container. 
       FIGS. 4-5  show the removable filter  500  separated/disengaged from the main chamber  200  of the device. The removable filter  500  is configured to fit into and be inserted and removed within the aperture  290  in the aperture side portion  270  of the main chamber  200 . The main body  505  of the removable filter  500  serves as a handle portion  590  for removing/disengaging the removable filter  500  from the main chamber  200 . In an aspect, the handle portion  590  of the removable filter  500  has tapered/curved edges  595  that correspond with the tapered/curved edges  295  of the aperture side portion  270 . This provides a seal when the removable filter  500  is inserted into the aperture  290  of the aperture side portion  270  of the main chamber  200  and makes it easy to manipulate the device  100 . In an aspect, when the handle portion  590  of the removable filter  500  is compressed, the tapered edges  595  disengage from the corresponding tapered edges  295  of the aperture  290  to easily disengage the removable filter  500  from the main chamber  200 . 
     The removable filter  500  is configured to fit into the main chamber  200  in between the first inlet  300  and the second inlet  400  in between the fluid pathway from the endoscope  700  and the vacuum  800  (see  FIG. 7 ). The removable filter  500  is configured to be inserted and removably retained within the aperture  290  in the side portion  270  of the main chamber  200  creating a seal between the main chamber  200  and the removable filter  500 . The biological specimen is extracted from the individual and trapped on the removable filter  500  while the device  100  is placed under suction. 
     In an aspect, both the main chamber  200  and the removable filter  500  of the device  100  are made from polypropylene material, which provides a better seal between the removable filter  500  and the main chamber  200  of the device  100  when in use. In an aspect, the removable filter  500  is made from plastic or a similar high-contrast material such as ABS, polypropylene and polycarbonate, to allow for easy viewing of the trapped biological specimen within the device  100  and to maximize compatibility with specimen containers  900 . In a preferred embodiment, the removable filter  500  is dimensioned to fit entirely within an average sized specimen container  900 . In an aspect, such specimen containers  900  can have dimensions that are approximately 45 mm in diameter and 50 mm in height. However, the dimensions can vary. 
     In an aspect, the main chamber  200  includes a support shelf  410  such that the filter  500  is supported during use whereon the specimen shelf  510  of the removable filter  500  abuts when inserted, ensuring a secure fit and tight seal. In other embodiments, the chamber  200  does not have a shelf  410 . The connecting joints  330  (see  FIG. 4 ) between the inlets  300 ,  400  and the main chamber  200  include small lips to optimize seal performance. 
       FIG. 6  is a top section view of the device showing the removable filter  500  separated from the main chamber  200  of the device  100 . The top surface  530  of the specimen shelf  510  of the removable filter  500  comprises small pores  550  disposed along the top surface  530  of the specimen shelf  510  that allow fluid to pass through when the device  100  is under suction. In an exemplary aspect, each pore  550  has a diameter of approximately 0.75 mm and the pores  550  are spaced approximately 1.3 mm from one another. The pores  550  can take various forms, as well as different geometrical patterns. In an aspect, the pores  550  can have hexagonal, square, or rectangular symmetry. In an aspect, the pores  550  take up approximately 15.5% of the available surface area on the specimen shelf. The spacing of the pores  550  allows the device  100  to maintain high suction when in use while maintaining the appropriate pore size for specimen collection. The spacing and the size of the pores  550  can vary in other embodiments. In other aspects, the pores  550  can take up between 5% to 25% of the surface area of the specimen shelf. Regardless of the different dimensions, the pores  550  should be of a size that allow fluid to travel through and maintain high suction while preventing a specimen from traveling through a pore  550 . 
       FIG. 7  is a schematic representation of the assembly according to an aspect of the present invention. The inlet  300  of the device  100  is connected to a medical scope  700  such as a colonoscope, endoscope or the like via a flexible tube  600 . The outlet  400  of the device  100  is connected to a suction line/vacuum system  800  with another flexible tube  600 . The flexible tube  600  is made from silicon or like material. The medical scope  700  is inserted into an individual during a surgical procedure such as an endoscopy or laparoscopy. The assembly comprising the medical scope  700  and device  100  is placed under suction using the vacuum system  800 . The medical scope  700  is used to isolate/remove the desired biological specimen from the individual. The biological specimen is then suctioned through the first inlet  300 , landing on the specimen shelf  510  of the removable filter  500  within the main chamber  200  of the device  100 . The removable filter  500  is then detached from the main chamber  200  of the device  100  and the removable filter containing the specimen is deposited into a specimen container  900 . The removable filter  500  is replaced with a new/unused removable filter  500  and additional biological specimens can be extracted and deposited as required. 
     In an exemplary aspect, when the removable filter  500  is inserted into the main chamber  200 , this assembly measures 38 mm horizontally and 20 mm vertically. The dimensions of the device  100  and removable filter  500  allow for the removable filter  500  to be entirely deposited into a specimen container. However, the device  100  and its components are not limited to such dimension, and in other aspects, the dimensions can vary. However, in most aspects, the device  100  and the removable filter  500  have dimensions that allow the removable filter  500  to fit into a specimen container  900  while still maintaining a high suction efficiency when inserted into the main chamber  200 . 
     The composition of the device  100  as discussed above has been shown to have benefits over other commercially available products. As shown in  FIG. 8A , the device  100  volume is approximately 400% smaller than the smallest commercially available device on the market. The small, compact size of the device  100  makes the device  100  easy for the user to manipulate use, as well as remove and reinsert removable filters  500  during a medical procedure. The size also ensures that the removable filter  500  and its contents can be deposited entirely into a specimen container. 
       FIG. 8B  shows the vacuum pressure of the device  100  over multiple trials in comparison to commercially available devices. The device  100  exhibits stable pressure over three trials and provides a more consistent performance profile with less variation than other solutions. By employing a closed system featuring optimized seals and ergonomics including the external curvature of the main chamber  200  and removable filter  500 , the device  100  is able to maintain stable pressure over multiple uses. 
       FIG. 8C  shows the average vacuum efficiency of the device  100  in comparison to commercially available devices using a 20 inHg/67.7 kPa vacuum source (within range of standard hospital vacuum systems). The device  100  exhibits less variation in its efficiency than any other device. The alternative devices are unable to maintain vacuum efficiency effectively after the being opened/used once and are therefore not ideal for insertion and removal of a removable filter  500  repeatedly during a medical procedure. No commercially available device offers all of the advantages of the present device  100  which include being small enough for easy manipulation, having a removable filter that fits entirely within a specimen container while also maintaining vacuum efficiency and pressure over multiple uses. 
     In an optional embodiment, the biological specimen receiving device, also termed as specimen container  900 , of the present specification is designed to include a receiving structure positioned within, and internal to, the main chamber of the device. A container comprising a luminescent or glow material may be placed within the receiving structure to illuminate the internal chamber or volume of the device, thereby enabling a specimen placed in a filter, as described above, in the main chamber to be seen clearly via an endoscopic device. In one embodiment, the main chamber of the device comprises polyethylene terephthalate, polycarbonate, or any other transparent material. The filter may be comprised of thermoplastic elastomer, thermoplastic polyurethane, silicone or other flexible material. Finally, the luminescent material is chosen to meet biological safety and/or regulatory requirements. 
       FIG. 9A  illustrates a receiving structure  902  coupled with an internal wall of a main chamber  901  of a specimen container  900 , in accordance with an embodiment of the present specification. Specimen container  900  is configured to receive a biological specimen in a main chamber  901  of the container  900 .  FIG. 9B  illustrates a front view of the receiving structure  902  shown in  FIG. 9A , in accordance with an embodiment of the present specification.  FIG. 9C  illustrates a side view of the receiving structure  902  shown in  FIG. 9A , in accordance with an embodiment of the present specification. In one embodiment, the receiving structure  902  is molded into, or onto, a surface of the internal walls of the interior portion  910  of main chamber of specimen container  900 . In another embodiment, the receiving structure  902  is welded, glued, or clipped into, or onto, a surface of the interior portion  910  of main chamber of specimen container  900 . In embodiments, the receiving structure  902  may be of any shape that is capable of mating with, and snapping into, the main chamber  901  of the specimen container  900 . 
     In an aspect, receiving structure  902  of the specimen container  900  is made from a transparent material, including, but not limited to, clear plastic, and is the same material as the main chamber  901 . In other aspects, other transparent materials can be utilized. While non-transparent materials can be used, it is preferable to use a transparent material in order to see when a biological sample has entered the main chamber  901  and is trapped on the removable filter, which has been discussed in detail above. 
     Referring to  FIGS. 9A, 9B and 9C , in an aspect, the main chamber  901  comprises an interior portion  910  ( 210  in  FIG. 1 ), an exterior portion  920  ( 220  in  FIG. 1 ), a top portion  930  ( 230  in  FIG. 1 ), a middle portion  940  ( 240  in  FIG. 1 ), a bottom portion  950  ( 250  in  FIG. 1 ), an aperture  990  ( 290  in  FIG. 1 ), an aperture side portion  970  ( 270  in  FIG. 1 ), and a non-aperture side portion  980  ( 280  in  FIG. 1 ). The side portion  970  of the specimen container  900  is curved, providing superior ergonomics and ensuring ease of manipulation by the end user. 
     The main chamber  901  is tapered/rounded along its edges between the top portion  930  and bottom portion  950 . In an aspect, the top portions  930  and the bottom portions  950  have equal heights to improve the ergonomics of the chamber  901 . In an exemplary aspect, the main chamber includes a middle portion  940  that is tapered/rounded along the aperture side and non-aperture side portions  970 ,  980 . The first and second inlets  994 ,  996  extend from the top portion  930  and the bottom portion  950  of the chamber  901  respectively (shown in  FIG. 9A ). In an aspect, the first inlet  994  and the second inlet (outlet)  996  are tubular extensions in communication with the interior portion  910  of the main chamber  901 . Specifically, inlet  994  is oriented on the top portion  930  of the main chamber  901  of the specimen container  900  and the second inlet (outlet)  996  is oriented on the bottom portion  950  of the main chamber  901  of the specimen container  900 . In an embodiment, the inlet  994  is oriented on the non-aperture side  980  of the main chamber  901  and the second inlet (outlet)  996  is oriented in the middle of the bottom portion  950  of the main chamber  901 . The removable filter (shown in  FIGS. 1-7 ) is configured to fit into the main chamber  901  in between the first inlet  994  and the second inlet  996  in between the fluid pathway from the endoscope and the vacuum (see  FIG. 7 ). The removable filter is configured to be inserted and removably retained within the aperture  990  in the side portion  970  of the main chamber of specimen container  900  creating a seal between the main chamber of specimen container  900  and the removable filter. In embodiments, the receiving structure  902  comprises a first elongated wall  905   a  encasing the internal hollow space, wherein the first wall  905   a  is connected to and abuts internal wall  904  of the main chamber  901  of specimen container  900 . Receiving structure also comprises a second elongated wall  905   b , which is connected to a top portion of first elongated wall  905   a  and a third elongated wall  905   c , which is connected to a bottom portion of first elongated wall  905   a . Second elongated wall  905   b  and third elongated wall  905   c  are curved toward each other to form an opening/slot  906  extending throughout a length of the receiving structure  902  as shown in  FIG. 9A . 
     In embodiments, the receiving structure  902  is positioned toward the bottom portion  950  of main chamber  901 , and close to inlet  996 , which is oriented in the middle of the bottom portion  950  of main chamber  901 . Thus, the receiving structure  902  is positioned such that it does not interfere with the insertion of the removable filter. Receiving structure  902  is configured to position at least one lighting element within it. The lighting element includes a luminous material that is self-illuminated, without the need for an external power source connected to the lighting element. Embodiments of the luminous material may include, but is not limited to, one or more of Dimethyl Phthalate, 2-Dipropylene Glycol Dimethyl Ether, and Hydrogen Peroxide. It should be noted that any suitable luminous material may be used as long as it achieves the objectives of the present specification. 
     The lighting element is used to provide light for viewing the sample collected on the filter. In alternate embodiments, the receiving structure is positioned inside and/or outside the main chamber  901 . In some embodiments, the receiving structure is positioned above and/or below the filter. In various embodiments, the receiving structure is configured anywhere so that a lighting element placed within the receiving structure is capable of illuminating the sample collected on the filter. In embodiments where the receiving structure is positioned above the filter, the structure is configured to focus light on the sample while blocking light in other directions. In an embodiment, where a filter is positioned on a first side of the receiving structure in which the lighting element is placed, and a user views a sample placed in the filter through an endoscope for example, from the second side opposite to the first side, of the receiving structure; the surface of the receiving structure that is above the lighting element is blocked or configured to be opaque, so that only the first side of the receiving structure enables light from the lighting element to reflect on the specimen placed in a filter. Blocking one side of the receiving structure enables the light to be focused on the sample and avoids the possibility of a glare in the endoscopic vision. 
     In an embodiment, a portion of the receiving structure  902  is cylindrical in shape and comprises an internal hollow cylindrical space for receiving a cylindrically shaped stick filled with luminescent material (glow-stick). In different embodiments, the receiving structure  902  is hollow and shaped in the form of either a cylinder, a cuboid, a triangular prism, or any other shape so as to achieve the objectives of the present specification. In an embodiment, as shown in  FIG. 9A , a front circular end of the receiving structure  902  is open and may be used for insertion of a cylindrically shaped container comprising a luminescent material to be placed within the internal hollow cylindrical space of the structure  902 . In different embodiments, an opposing circular end (distal to the front end) of the receiving structure  902  may be open, rounded and closed, or flush with an internal back wall of the main chamber  901 . In other embodiments, the receiving structure  902  may be of any shape and may receive a correspondingly shaped container comprising a luminescent material. In embodiments, the shape of the receiving structure  902  is designed such that a container containing the luminescent material can be inserted into said receiving structure such that it mates with and can be snapped into place into said receiving structure  902 . 
     It should be appreciated that the volume of luminescent material is important. A small amount would result in an effective illumination of the area of interest. Too large an amount would be unnecessary, bulky, and possibly interfere with the filtering process. In one embodiment, the volume of luminescent material ranges from 10 mm 3  to 10000 mm 3  and may be incorporated into a container having any geometrical shape, including cylindrical (as described above), triangular, rectangular, spherical or other polygonal shapes. In embodiments, the volume of the luminescent material depends on the size of the main chamber of the biological sample catching device. For example, a larger device is equipped with a larger volume of the luminescent material. 
       FIG. 9D  illustrates a container comprising a luminescent material  911  placed in the receiving structure  902  shown in  FIG. 9A , in accordance with an embodiment of the present specification.  FIG. 9E  illustrates a front view of the container comprising a luminescent material  911  placed in the receiving structure  902  shown in  FIG. 9A , in accordance with an embodiment of the present specification.  FIG. 9F  illustrates a side view of the container comprising a luminescent  911  or glow material placed in the receiving structure  902  shown in  FIG. 9A , in accordance with an embodiment of the present specification.  FIG. 9G  is a side perspective view of the container comprising a luminescent or glow material  911  placed within the receiving structure  902  shown in  FIG. 9A , in accordance with an embodiment of the present specification.  FIG. 9H  illustrates another side view from the aperture side  970  of the container comprising a luminescent or glow material  911  placed in the receiving structure  902  shown in  FIG. 9A , in accordance with an embodiment of the present specification. Referring to  FIGS. 9A-9H , a container  911  comprising a luminescent material having dimensions in order to fit within the hollow opening/slot  906  inside of the receiving structure  902  is placed within the internal hollow cylindrical space  906  of the receiving structure  902 . In embodiments, any type of luminescent material filled in a container that mates with the receiving structure  902  may be used. In an embodiment, the container  911  comprising a luminescent material may be inserted within the receiving structure  902  via the opening/slot  906 . In another embodiment, container  911  comprising a luminescent material may be inserted within the receiving structure  902  through the front circular open end. The position of the lighting element of container  911 , owing to the position of receiving structure  902 , is such that it does not interfere with the insertion of the removable filter. 
       FIGS. 10A to 10C  illustrate different views of the specimen container  900  of  FIGS. 9A to 9F , including a specimen shelf  1020  (also shown as specimen shelf  510  of  FIG. 3 ), in accordance with some embodiments of the present specification.  FIG. 10A  illustrates a first elongated side perspective view of the biological specimen receiving device  1000  with specimen shelf  1020 .  FIG. 10B  illustrates an elongated front view of the biological specimen receiving device  1000  with specimen shelf  1020 .  FIG. 10C  illustrates a second elongated side perspective view of the biological specimen receiving device  1000  with specimen shelf  1020 . Referring simultaneously to  FIGS. 10A, 10B, and 10C , all the components including a receiving structure  1002 , a main chamber  1001 , an inlet  1004 , and an outlet  1006 , are identical to the corresponding components described in  FIGS. 9A to 9F . Details of these components are not repeated here for brevity. In embodiments, the specimen shelf  1020  is removable and can be slid and/or is friction-fit between side portions  930  and  970 . In some embodiments, a top surface of the main chamber  1001  is configured with a magnifying lens  1003  to provide an additional optical access to view a collected sample. 
     Specimen shelf  1020  is configured to cover the open side of the main chamber  1001 , in between the inlet  1004  and the outlet  1006 , and further in between the side portions  1030  and  1070 . A surface of specimen shelf  1020  curves along and extends between the edges of side portions  1030  and  1070 . Specimen shelf  1020  is configured to be inserted and removably retained at a side of the aperture between the side portions  1030  and  1070  of the main chamber  1001 , thereby creating a seal. A friction grip  1022  is configured on both sides of the external curved surface of component  1020 , to provide an ergonomic grip to a user to hold and attach or detach the specimen shelf  1020  from the main chamber  1001 . 
       FIG. 11A  illustrates a bottom-up view of the specimen container  900  and  1000  of  FIGS. 9A to 9F  and  FIGS. 10A to 10C , in accordance with embodiments of the present specification.  FIG. 11B  illustrates a top-down view of the specimen container  900  and  1000  of  FIGS. 9A to 9F  and  FIGS. 10A to 10C , in accordance with embodiments of the present specification.  FIG. 11C  illustrates a top-down perspective view of the specimen container  900  and  1000  of  FIGS. 9A to 9F  and  FIGS. 10A to 10C , in accordance with embodiments of the present specification. 
       FIG. 12  is a flowchart illustrating a method of illuminating a main chamber of a biological specimen receiving device, in accordance with an embodiment of the present specification. At step  1202 , a light emitting body contained in a container having predefined shape and dimensions is activated. In embodiments, the light emitting body is a luminescent material which is in the form of a light emitting diode (LED) or a glow stick and may be activated such that it emits light by using any of the known methods of activating a circuit or activating glow sticks, such as but not limited to, shaking the stick vigorously to mix fluidic chemicals contained in the stick or snapping the stick, breaking a seal, or pressing on the luminescent material container in a predefined way, wherein a chemical mixture formed by virtue of the physical manipulation of the container, emits light. In other embodiments, various other methods may be employed to activate different types of luminescent materials. 
     At step  1204  the container comprising the activated luminescent material is inserted into a receiving structure formed in the main chamber of the biological specimen receiving device as described above. In an embodiment, the receiving structure has a cylindrical shape and is coupled with a side internal wall of the device, as described with reference to  FIGS. 9A-9D  above. In an embodiment the container comprising the luminescent material is also cylindrically shaped and designed to fit in the cylindrically shaped receiving structure. In other embodiments, different shapes of receiving structures may be employed and the structure may be coupled with different portions of the internal walls of the main chamber of the device. 
     At step  1206  a filter for sample collection is inserted into the main chamber. At step  1208  the device is coupled with an endoscope and a vacuum generator such that it can be used for biological sample collection as described with reference to  FIGS. 1-7  above. 
     The specimen container comprises a light emitting body/luminescent material, or glow material that may be placed within its receiving structure to illuminate an internal chamber or volume of the device, thereby enabling a specimen placed in a filter, as described above, in the main chamber to be clearly seen using an endoscopic device. The luminescent material is chosen to meet biological safety and/or regulatory requirements. Additionally, the dimensions and volume of the luminescent material are adjusted to the dimensions of the specimen container such that the luminescent material is neither too small relative to volume of the internal chamber, nor too big. In embodiments, the luminescent material has a volume ranging from 200 cubic millimeters (mm 3 ) to 600 mm 3 . In one embodiment, the luminescent material has a volume of 283 cubic millimeter (mm 3 ). In another embodiment, the luminescent material has a volume of 500 mm 3 . A relatively small volume of the luminescent material compared to the internal chamber volume may result in the light emitted by the material being insufficient to illuminate the biological sample. On the other hand, a relatively large volume of the luminescent material within the internal chamber, may result in an obstacle in the flow path between the inlet and the outlet at the top and bottom portions of the container. Thus, the volume of the luminescent material is, in one embodiment, a function of the internal volume of the space. Accordingly, if the internal volume is 6000 mm 3  to 120000 mm 3  (or any numerical increment therein), the volume of luminescent material may be linearly scaled in a range of 140 mm 3  to 2800 mm 3  (or any numerical increment therein). 
       FIG. 13A  is a side view  1302   a  and a front view  1304   a  illustration of a specimen container  1300   a , showing exemplary dimensions, in accordance with some embodiments of the present specification. The various components of the container  1300   a  are similar to those already described above in context of  FIGS. 1-7 , and  FIGS. 9A-9H , and are therefore not repeated here for brevity. The main chamber  1301   a  extends longitudinally between top portion  1330   a  and bottom portion  1350   a  and has a length or height of approximately 20 millimeters (mm); and latitudinally between an aperture side portion  1370   a  and an opposing non-aperture side portion  1380   a  and has a width of approximately 40 mm. A depth or thickness between two parallel walls that lie between the top portion  1330   a  and bottom portion  1350   a , and between aperture side  1370   a  and opposing non-aperture side  1380   a , is approximately 15 mm. In embodiments, inlet  1394   a  is oriented on and perpendicular to the surface of the top portion  1330   a  of the main chamber  1301   a  of the specimen container  1300   a . The outlet  1396   a  is oriented on and perpendicular to the bottom portion  1350   a  of the main chamber  1301   a  of the specimen container  1300   a.    
       FIG. 13B  illustrates a side view  1302   b  and a front view  1304   b , with exemplary dimensions, of another specimen container  1300   b , in accordance with some embodiments of the present specification. The various components of the container  1300   b  are similar to those already described above in context of  FIGS. 1-7, and 9A-9H , and are therefore not repeated here for brevity. The main chamber  1301   b  extends longitudinally between top portion  1330   b  and bottom portion  1350   b  and has a length or height of approximately 30 mm; and latitudinally between an aperture side portion  1370   b  and an opposing non-aperture side portion  1380   b  and has a width of approximately 80 mm. A depth or thickness between two parallel walls that lie between the top portion  1330   b  and bottom portion  1350   b , and between aperture side  1370   b  and opposing non-aperture side  1380   b , is approximately 30 mm. In embodiments, inlet  1394   b  is oriented on and at an angle to the surface of the top portion  1330   b  of the main chamber  1301   b  of the specimen container  1300   b . In one embodiment, the inlet  1394   b  forms an angle of approximately 45 degrees with the surface of the top portion  1330   b . The outlet  1396   b  is oriented on and perpendicular to the bottom portion  1350   b  of the main chamber  1301   b  of the specimen container  1300   b.    
       FIG. 13C  is a cross-sectional illustration  1302   c  of side view  1302   b  shown in  FIG. 13B . The figure shows a flow path from inlet  1394   c  at an angle of approximately 45 degrees, into the main chamber  1301   c . During operation of the specimen container  1300   c , a biological specimen is suctioned through inlet  1394   c  so that it glides smoothly through inlet  1394   c  and lands on a specimen shelf  1310   c  within the main chamber  1301   c .
