Specimen Gathering - Perez

Intro

This invention relates to the gathering of biological specimens, e.g. DNA, from target areas or items, e.g. weapons, on a crime scene or elsewhere. Although DNA can be gathered, doing so at the scene is often difficult. DNA often becomes compromised or lost. This invention is a kit for the collection of biological samples, which enhances DNA and destroys bacteria that may potentially degrade it.

  1. A specimen gathering kit comprising: a specimen gathering device including: a swab member having opposing ends, wherein one end comprises a swab tip; a housing including a base and a cap; and a solution; wherein the housing base defines a solution chamber having a closed end and an opposite open end and wherein the solution is received within the solution chamber; and wherein the base and the cap are releasably joined together to house the swab member, the swab member being lodged within the cap with the end of the swab member opposite the tip extending into the solution chamber and the swab member protruding from the open end of the solution chamber; wherein the swab member seals the open end of the solution chamber to contain the solution therein; and wherein the solution comprises a buffer solution including a DNA preservative configured to gather the specimen.
  2. The specimen gathering kit of claim 1 wherein the buffer solution comprises distilled water.
  3. The specimen gathering kit of claim 1 further comprising Ethylenediaminetetraacetic Acid (EDTA).
  4. The specimen gathering kit of claim 3 further comprising Sodium Chloride (NaCl).
  5. The specimen gathering kit of claim 4 further comprising Sodium phosphate, dibasic (Na2HPO4).
  6. The specimen gathering kit of claim 5 further comprising Potassium phosphate, Monobasic (K2HPO4).
  7. The specimen gathering kit of claim 6 further comprising Potassium chloride (KCl). 
  8. The specimen gathering kit of claim 7 further comprising Glycerol. 
  9. The specimen gathering kit of claim 1 wherein the preservative comprises a biocide.
  10. The specimen gathering kit of claim 9 wherein the biocide comprises an antimicrobial.
  11. The specimen gathering kit of claim 1 wherein the opposite end of the swab is movable to unseal the solution chamber and allow the solution to flow out of the solution chamber and to come into fluid communication with the swab tip.
  12. The specimen gathering kit of claim 1 further comprising an indicator that changes color upon contact with a selected material.
  13. The specimen gathering kit of claim 1 wherein the specimen gathering device comprises illumination means.
  14. The specimen gathering kit of claim 1 wherein the kit further comprises a container, the specimen gathering device being received within the container.
  15. The specimen gathering kit of claim 14, wherein the container comprises a re-sealable bag.
  16. The specimen gathering kit of claim 15, wherein the re-sealable bag comprises at least two sealing closures.
  17. The specimen gathering kit of claim 16, wherein the re-sealable bag further comprises pre-formatted areas to enter information.
  18. The specimen gathering kit of claim 17, wherein the kit further comprises an insert bag, the specimen gathering device being received within the insert bag, and the insert bag with the specimen gathering device therein being received within the re-sealable bag.
  19. The specimen gathering kit of claim 14 further comprising instructions for collecting a specimen.
  20. The specimen gathering kit of claim 14 further comprising at least two specimen gathering devices within the container.
  21. A specimen gathering kit comprising: a specimen gathering device including: a swab member having opposing ends, wherein one end comprises a swab; a housing including a base and a cap; and a solution including a preservative; a first container sealing therein the specimen gathering device; a second container re-sealably sealing therein the first container containing the specimen gathering device sealed therein; and wherein the housing base defines a solution chamber having a closed end and an opposite open end and wherein the solution is received within the solution chamber; and wherein the base and the cap are releasably joined together to house the swab member, the swab member being lodged within the base with the opposite end of the swab extending into the solution chamber and the swab protruding from the open end of the solution chamber; and wherein the swab member initially seals the open end of the solution chamber to contain the solution therein; and wherein the swab member is moveable to un-seal the chamber to allow the solution to come into fluid communication with the swab.
