FIELD OF THE INVENTION
The field of the present invention is devices for collecting biological samples. In particular, the several embodiments of the present invention provide a device having an absorbent for collection of oral fluids or blood specimens or cells thereon. Several embodiments of the specimen collection devices provide for recordation of identifying information and for division of the sample into separate identifiable portions to permit use of the specimen as law enforcement evidence. Generally, the embodiments of the invention further provide a holder for containing and/or securing the original specimen collection material or paper or absorbent that was used in the actual collection of the biological specimen or sample. The holder permits the original collection paper or absorbent to be processed by automated analysis equipment by securing the collection paper or absorbent in a holder that is structured to permit extraction of a test sample while maintaining the evidentiary requirements necessary for a proper chain of custody.
The invention allows for collecting saliva from the mouth or blood samples from a suspect or mammal or DNA samples while later permitting extraction of portions of the sample collection absorbent for testing while maintaining the chain of evidence and identification of the specimen of saliva or blood.
BACKGROUND OF THE INVENTION
Increasingly in law enforcement it is necessary to collect biological samples as evidence of a crime or for use as identifying information of a particular human as is the case of DNA collection from suspects. In the collection of biological specimens, it is necessary to associate information about the subject with the specimen at the time of collection as there is no manner for identifying a biological specimen by simple inspection. Therefore, a useful form of evidence collection device for use with biological specimens will contain, at least, a suspect information portion for recording subject information data thereon.
The use of biological specimens as evidence further requires that the biological specimen be securely associated with the identifying information so as to assure that after collection of the specimen, the collection paper or absorbent cannot be intentionally or inadvertently switched to a different collection paper. At a minimum, a proper evidence collection device or holder should easily and clearly show that tampering was attempted either by damage to delicate indicia on the device or by overt damage to a strongly secured device. It is further beneficial if the evidence collection device can accommodate additional forms of evidence such as the application and storage of finger prints on the evidence holder.
A particular issue in the collection of the biological sample is that the sample collection is often taken from a living, uncooperative person. Often the sample is to be taken from the mouth of the suspect where a saliva or DNA specimen is needed. In this instance, the collection absorbent used with be attached to a handle or a stick. Once the specimen is on the absorbent, the handle is no longer needed, a present complicating factor in specimen storage and analysis due to the extra bulk and size.
The foregoing issues relate, generally, to a process referred to as evidence “chain of custody.” “Chain of custody” encompasses the procedures and documentation used to maintain and demonstrate the chronological history of the evidence. Documentation should include, for example, name or initials of the individual collecting the evidence, each person or entity subsequently having custody of it, dates the items were collected or transferred, agency and case number, victim's or suspect's name, and a brief description of the item. In biological samples, the principles of evidence or sample identification involved in maintaining proper “chain of custody” are especially critical as a fluid or cellular biological sample, once collected onto an absorbent presents no distinguishing characteristics. This lack of visual characteristics foils any attempt to properly identify such a biological fluid or cellular sample once it has become separated from its identifying information.
Another problem or issue presented in the analysis of biological specimens is the need to extract or transfer the collected sample from the original collection absorbent and onto an alternate medium to permit analysis or testing of the specimen using the analysis equipment that is available in the selected laboratory. Often it is necessary to separate the collection absorbent from its originally obtained identifying information that is directly associated with the original collection absorbent. This separation of specimen from identifying information can lead to mistakes in associating the specimen with the correct subject or suspect or can lead to the “chain of custody” being open to question in court and a failure of proof of a crime. Sample misidentification is a major source of error both in laboratory analysis and in substantiating criminal evidence.
An additional issue associated with the collection of the biological sample is the need to test or analyze the sample for comparison purposes with other specimens. The sample analysis must be conducted using preexisting instrumentation which is not amenable to maintaining the “chain of custody” of a biological specimen absorbent. For example, in automatic sample testing devices originally designed for the insurance testing industry, the standards of assuring the association of a specimen with its identifying information is not as rigorous as is required for evidence “chain of custody.”
Therefore, it would be a benefit if a biological sample holder and storage device were available which securely associated the biological specimen absorbent with the subject identifying information and which permitted removal of any handle portion attached to the collection absorbent and which was tamper proof or tamper evident and which provided ease of use for the collection law enforcement officer while in the field.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
The purpose of the various inventive sample holders or specimen/sample carriage devices shown in the present application is to meet collection requirements which allow blood specimen collection or body fluid collection or DNA collection to qualify for secure evidence handling and for chain of custody proof requirements in law enforcement. In particular, in an optimal situation, it is desirable that the sample holder used for adapting the sample or specimen collection device to an automated sampling system incorporate the original specimen collection absorbent and avoid the need for any transfer of the specimen onto a second absorbent or require the transfer of a bar code or other identifying material from the collection absorbent or DNA collector or sampling device onto the sample device holder. It is far more desirable and preferable that the original specimen collection absorbent and the same bar code that is attached to the original sample or specimen collection absorbent or device be inserted into the sample holder and be viewable from within the sample or specimen holder. It also is important that the absorbent or sampling paper surface, while held within the holder, be exposed so that small portions or circles can be punched from the paper for delivery into testing vials for making the DNA determination.
It is also another important feature that the sample holder have a locking feature so that once the sample collection device and/or absorbent is fixed within the holder, it is locked into the holder, and the holder cannot be tampered with or opened without the damage being evident. It is another benefit if the holder for such automated sampling avoids a secondary transfer of the original collection absorbent 110 (FIG. 10) of collector or collection device 106 (FIG. 10) or any destruction of the original sample device 106 and/or collection absorbent 110 and maintains the original collection absorbent 110 (FIG. 10) attached or within its handle and bearing its original bar code marking and other identifying markings. This is desirable to eliminate any mix up between samples due to transfer of the original identifiers associated with the sample during the moment of sample collection onto sample holders used during analysis of the sample. It is another important benefit that separation of the sample from the handle or transfer of bar codes or other identity material be avoided. This is desirable to avoid complication of the chain of custody and to make an unambiguous association between the device that received the subject's blood specimen or went into the subject's mouth to collect the sample and the sample that appears in the laboratory for analysis.
Referring now to FIGS. 1-3, a sample carriage device embodiment 10 is shown which allows the paper absorbent 110 of the specimen/sample collector 106 to be inserted into the carriage device 10 and the paper absorbent 110 captured within the carriage device and the paper separated from the collector handle 114 (FIG. 10) by serrated edges 21 on device 10.
Referring to FIG. 1, embodiment 10 is comprised of an upper portion 12 which is connected to a bottom portion 14 by the use of a hinge means or staple connection or fold along back edge 16 to permit top portion 12 to be separable from bottom portion 14 along front edge 18. Front edge 18 includes cutter portion 21 having teeth-like edges or serrations in front edge 18 the purpose of which shall be described hereinafter.
In operation, a specimen or sample collector 106 such as the one shown in FIGS. 8-10 can be used with any of the embodiments of FIGS. 1-7. Other configurations or shapes of absorbents 110 may be used if the registration track or groove 22 of the sample carriage 10 is reconfigured to accept the alternate absorbent shape. The sample carriage 10 shown in FIGS. 1-3 may be operated by removing the handle portion 106 from holder 108 (FIG. 10) and inserting collection absorbent or paper 110, having a specimen or sample thereon, into device 10 such that absorbent or paper 110 is visible within viewing or sample collection area or window 24.
Once the collection paper 110 is positioned so as to be captured within the registration track or groove 22 of holder 10, top portion 12 is pressed against bottom portion 14 to secure absorbent 110 therebetween. Top portion 12 and bottom portion 14 are then held together by a securing means. In device 10 top portion 12 and bottom portion 14 are held together by a frictional fit between top portion 12 and bottom portion 14 as top portion 12 fits into a recessed area 28 of bottom portion 14. Alternatively, or additionally, the securing means may be a post 32 insertable into a detent 34 to lock together top portion 12 and bottom portion 14 as is shown in FIGS. 4-5 for embodiment 30 (FIG. 4). Alternative securing means will be apparent to those skilled in the art, means such as glue or tape or a staple or adhesive strip or a peel and stick or release liner or any convenient means of securing the two surfaces together to hold collection absorbent paper 110 within top portion 12 and bottom portion 14 also may be used. When absorbent paper 110 is secured within the holder 10, serration or cutter 21 may be used to separate the paper 110 from handle portion 106 by using the cutter 21 to separate handle 106 from absorbent 110. This then will present sample absorbent paper 110 locked into the device 10 as is shown in FIG. 3 wherein absorbent sample paper 110 is shown by the cross hatch marks within the window 24 and with the paper now bearing reference numeral 110 to indicate that it is the absorbent sample paper 110 taken from the holder 106.
Once sample paper 110 is fixed within the holder 10, the paper may then be loaded into an automated sampling device such as an automated sample punching machine such as a BSD-1000 manufactured in Australia. The automated sampling device will read bar code 26 on top surface 12 of device 10. A typical automated sampling device will then punch samples from collection paper 110 as it is held within window 24 of holder 10. It will be appreciated that bar code 26 is bar code 152b shown on collection device 106 in FIG. 10 and which has been transferred to the holder 10 during the process of capturing collection absorbent paper 110 within holder 10. Alternatively, a duplicate version of bar code 152b may be produced and placed on device 10 to serve as bar code 26.
Referring now to FIGS. 4 and 5, another embodiment, device 40, is shown which is similar in construction to device 10 of FIGS. 1-3. In describing device 40 the same reference numbers will be used in describing structures that are similar to structures found in device 10. Device or sample holder 40 is comprised of a top or upper portion 12 which is separate from bottom portion 14. As upper or top portion 12 is fully separable from bottom portion 14 a securing means is provided to connect upper portion 12 to bottom portion 14 after absorbent 110 has been inserted into registration track or groove 22 of bottom portion 14. In the embodiment of device 40 the securing means is post 32 which is inserted into void or detent 34 and which is captured therein. Device 40 also includes a cutter portion 21 with teeth-like edges or serrations that serve to allow the user of device 40 to tear absorbent 110 from handle 114 of collector 106 when absorbent 110 has been captured between upper or top portion 12 and bottom portion 14.
It will be appreciated by those skilled in the art that devices 10 and 40, may involve the transfer of the identifying bar code 152b from the handle 106 of the collection device of FIG. 10 to sample holder 10 to provide the bar code shown in the position of bar code 26, however, it is possible to provide sample holder 10, 40 as a unit which includes a specimen collector such as collector 106, both of which devices are pre-provided with matching bar codes 26.
It also should be appreciated that the embodiments shown in FIGS. 1-5 involve modification of the structure of the device used to collect the sample. Specifically, the handle 114 is separated from paper 110 upon which the sample resides. While the embodiments of FIGS. 1-5 do not contain all the preferred features of a preferred embodiment, they will be functional for some purposes in which a chain of custody or evidentiary issues are not as strict as within criminal chain of custody matters.
The embodiment, shown in FIGS. 6 and 7, now to be described, provides all the preferred objects. Referring now to FIGS. 6-7, a specimen holder 50 is shown in which the entire collection handle 114 and collection paper 110 of collection device 106 (FIG. 10) is inserted into the holder 50. Holder 50 is comprised of an upper portion 12 and a bottom portion 14 which can be superimposed on one another and pressed together to interconnect to capture device 106 (FIG. 12) within registration groove 22 of holder 50. Top portion 12 and bottom portion 14 are held together, as described for the embodiments of FIG. 1-5, by any useful means of securing the top portion 12 to the bottom portion 14. Such means may be adhesive tape, staples, ultrasonic fusing of the material together if the holder were plastic, or an arrangement of locking posts and detents can be utilized such as is shown in FIGS. 6-7. In the embodiment of FIGS. 6 & 7, posts 32 are registerable and insertably lockable into detents 34. It also will be appreciated that the handle 114 can be shortened, if necessary, to fit into the device by cutting the handle 114 or providing a perforation line that allows breaking handle 114 to shorten it to a length compatible with holder 50.
In operation, the function of the embodiment 50 of FIGS. 6 & 7 is as follows: A handle sample holder 106 having a bar code 152b and having a collection absorbent or paper 110 attached thereto such as the collection device 106 of FIGS. 8-10 of the present application is inserted into bottom portion or half 14 of device 50. As is shown in FIG. 6, windows 52a, b and 54a, b are included on both top portion 12 and bottom portion 14 of holder 50. A support band 56 bridges windows 52a, b and 54a, b. Support band 56 supports device 106 within the holder 50 while allowing the bar code 152b on device 106 to be viewed and read with a bar code scanner and sample collection portion 110 of device 106 to be exposed and accessible and viewable at all times.
It will be appreciated that during manufacture, bottom portion 12 and top portion 14 of device 50 can be constructed so the top and bottom portions are identical. Thus, the individual inserting device 106 into the halves of the device need not select and match a top portion and a bottom portion. This can be achieved by simply manipulating the closure method so the top 12 and bottom 14 can be the same. In the case of the posts and detents, it would be possible to put all the posts on either the top or the bottom or on one edge of the device so identical tops and bottoms could be constructed.
In operation, after device 106 has been inserted into holder 50 and top portion 12 connected to bottom portion 14, the resulting assembly is as shown in FIG. 7. In FIG. 7, device 106 is locked within the compressed together top and bottom halves 12, 14 of device 50 and bar code 152b of device 106 is visible within window 52a and collection paper 110 is visible and accessible through window 54a, b. It will be appreciated that as window 54a is aligned with window 54b that a portion of collection absorbent 110 may be removed by use of a punch to extract a sample of collection paper or absorbent 110 for testing. In addition, it will be appreciated that the original bar code attached to sample collection device 106 is still attached to device 106 and is visible through window 52a of device 50. Further, if additional or alternate bar code or identification symbols are needed, they may be placed on device 50 as is shown by bar code label 26.
Referring now to FIG. 11, yet another embodiment of the holder, holder 60, will be discussed. Holder 60 is comprised of a holder bottom or body portion 14 to which is attached a foldable, closeable top portion or hood portion 12 and which is attached to body portion 14 at hinged edge 16. Attachment point or edge 16 can be any flexible hinge type of connection between body 14 and hood 12 which permits hingeable opening of portion 12 with respect to body 14. Alternatively, it will be appreciated by those skilled in the art that portion 12 could be a separate cover from body portion 14 and the two portions 12 and 14 made connectable by interlocking weld means or post and detent means or other connection means as previously described for the devices shown in FIGS. 1-7. Again, the object is to contain a collection device 106 within holder 60 while presenting the identifying bar code 152b and the sample collection paper or portion 110 visible and available for reading and for the punching of sample disks from collection paper 110.
In operation, device 60 of FIG. 11 is used as follows. A collection sample device such as device 106 of FIGS. 8-10 is placed on bottom portion 14 so that absorbent 110 covers window 24 on bottom 14 and handle 114 of device 106 is generally flush with the surface of bottom portion 14. Window 24 permits collection paper 110 to be viewed and paper disks to be punched from collection paper 110 when device 106 is mounted within holder 60. It will be appreciated that window 24 of top portion 12 of the device 60 has a similar window portion 24 directly opposite and in registration with the window of top 12 and which is in base portion 14. This alignment of windows 24 permits a paper disk to be punched from collection paper 110 as absorbent paper 110 is held within device 60. Further, the disk can fall out of holder 60 through window 24 in bottom portion 14 and into testing vial or dish.
It will be appreciated that when top portion 12 is pressed downwardly against base portion 14, the previously described securing means for securing device 106 within device 60 may be used and that top portion 12 cannot be opened or separated from base portion 14 without the tampering or the attempt to open being evidenced. In this manner, the chain of custody and evidentiary requirements are retained. Device 106 is adapted for use in an automated sampling machine without the need to separate collection paper 110 from handle 114 or the need to transfer identifying bar code 152b from device 106 onto a automated sampling holder device.
Referring now to FIGS. 13-15, a collection card 100 is shown having an embodiment of the specimen collection holder 150 attached thereto. The specimen holder 150 may be used alone in addition to being used, as shown, attached to information portion 175. Card 100 is comprised of an information portion 175 on which may be recorded the name 178, date of birth 180, sex 181, social security number 183, and other useful information regarding a suspect or convict such as the violation which qualifies for obtaining a biological specimen 184, and the date of collection 185, and the signature of the individual certifying that the offense for which the specimen was collected qualified as an offense which permitted the collection of biological information 186, and for which a blood or fluid or DNA specimen and other evidentiary information is to be obtained. The specimen can be collected in the manner previously described by use of a handle portion 106 having a collection paper 110 attached thereto. The paper may then be inserted into holder 150 which operates in a manner similar to the manner described previously for the embodiment shown in FIGS. 1-5 wherein the collection paper 110 attached to handle portion 106 is inserted into the holder 150 such that the paper is located in window 166. In the present embodiment, handle 114 is removed through the use of serrations 152 provided with the holder 150. Specifically, in the embodiment of FIGS. 13-15, collection paper 110 would be inserted into holder 150 in between upper portion or surface 154 and lower portion or surface 156, and upper surface 154 is then closed against lower surface 156 in the manner previously described herein to secure surface 154 against surface 156 and capture absorbent sample collection paper 110 therebetween using adhesive strip 160. Once the surfaces are secured together to contain specimen collection paper 110 therebetween, the cutter or serrations 152 may be used to separate handle 106 (FIG. 10) from collection paper 110.
In the embodiment of FIGS. 13-15, bar codes 176 are provided both on information portion 175 and on holder portion 150. In one embodiment, a bar code 176b, 176c is provided which spans across both information portion 175 (See, bar code 176b) and holder portion 150 (See, bar code 176c) such that if holder portion 150 is separated from information portion 175 by the use of perforation 158, both portions 175, 150 will contain an identical bar code identification 176 as it is printed to span perforation line 158.
An additional aspect of evidence which can be obtained by the use of the embodiment of FIGS. 13-15, is a fingerprint of the suspect or convict which can be placed into fingerprint block 162 which is on holder top portion 154. By the use of the embodiment shown in FIGS. 13-15, a law enforcement department can obtain all relevant and necessary information to identify a suspect or convict or other offender by the use of body fluid sample or DNA as well as by conventional forms of identification such as fingerprinting into block 160 and with identifying information placed into information portion 175 and a split bar code 176b, 176c correlating the physical evidence of holder portion 154 with the suspect information contained on information portion 175. A separate block 164 for imprinting a state department of justice identifier also is provided.
In FIG. 15 the reverse side of embodiment 100 is shown, including the reverse side 190 of information portion 175 and the reverse side 200 of holder portion 150. On the reverse side of the information portion areas for marking the date the card 100 was received at various locations 194 is provided, a space for a department of justice specimen number 164, identification and signature of the collecting agent 196 the name and signature of the subject 198 and space for a second fingerprint 192. The second finger print can further serve as a correlating marking proving that the individual whose biological sample and/or finger print appeared in holder 150 also was available to provide the finger or thumb print which was placed on the reverse side 190 of information portion 175.
Referring now to FIGS. 16 and 17 alternative embodiments 200, 200a are presented. In the embodiment of FIG. 16, a perforation line 158 is shown in the location described in the discussion of the embodiment of FIGS. 13-15. In the embodiment of FIG. 16, perforation line 158 allows separation of holder portion 150 from information portion 175 as was the case for the embodiment shown FIGS. 13-15. The embodiments shown in FIGS. 16 and 17 also contain a second perforation line 205 which serves to subdivide the sample holder 150, and the evidence contained thereon, into multiple sample portions 210, 215. This splitting of sample holder 150 into two sections 210, 215 permits separation of the biological specimen 110 (FIG. 17) and/or fingerprint evidence to be split into two portions. In the case of absorbent 110 (FIG. 17) is can be split into two portions 110a and 110b. This splitting permits a portion of the identical biological sample, for example, 110b, to be sent to a laboratory for analysis while a portion 110a is retained with the information portion 175 (FIG. 16) of the embodiment.
In the embodiment of FIG. 16, a bar code 176, 176b, 176c, 176c′, 176d is affixed to each portion of the embodiment with some representations of the bar code 176b, 176c, 176c′, 176d spanning two of the sections. As has been previously described, bar code 176b, 176c is placed across perforation 158 such that a portion of the bar code 176b, which is fully readable, remains with information portion 175, and a portion of the bar code 176c, which is fully readable, is retained with holder portion 150. In the embodiment shown in FIG. 16, which holder portion 150 can be split into two portions 210, 215 by use of perforation line 205, a second bar code 176c′, 176d is placed across perforation line 205 to permit identification of both halves of holder portion 210, 215 once perforation line 205 has been used to divide holder portion 150 into two halves 210, 215. It also will be appreciated that as the holder portion 150 of embodiments 200, 200a is separable into first and second halves 210, 215 that two fingerprint areas 162a, 162b are provided on each half 210, 215 of holder portion 150. It will be appreciated by those skilled in the art that it will be desirable in most cases that bar code 176c′, 176d be identical to bar code 176b, 176c and to bar code 176.
