Abstract

A self-administered tamper-evident drug detection system. The system includes a biometric detection surface for each of a user'"'"'s right and left hands, configured to identify the user and prevent tamper by continuously capturing biometric information from each of the user'"'"'s right and left hands while the system is administering a drug detection test. The system further includes a collection device to administer the drug detection test by exposing a sample collection device to a user'"'"'s mouth to collect a saliva sample.

Claims

1. A self-administered tamper-evident drug detection system comprising:

a biometric detection surface for each of a user'"'"'s right and left hands, configured to identify the user and prevent tamper by continuously capturing biometric information from each of the user'"'"'s right and left hands while the system is administering a drug detection test;

a collection device to administer the drug detection test by exposing a sample collection device to the user'"'"'s mouth to collect a saliva sample while the biometric information is being continuously captured;

wherein the system invalidates the drug detection test if the biometric information is not continuously validated throughout the entire drug detection test;

wherein the collection device is provided as a replaceable cartridge with multiple sample collection devices and a single sample collection device is exposed to the user for a period of time for testing and then mechanically retracted into the collection device for analysis; and

wherein the system includes a display that guides the user as to when to release the sample collection device from the user'"'"'s mouth.

2. The drug detection system of claim 1, wherein the system is contained in a single housing.

3. The drug detection system of claim 1, wherein the continuously captured biometric information is captured at a rate of 10-100 samples per second.

4. The drug detection system of claim 1, wherein the biometric information is biometric identification information.

5. The drug detection system of claim 4, wherein the biometric identification information includes at least one of:

a fingerprint, a handprint, and a vein pattern.

6. The drug detection system of claim 1, wherein the biometric information includes at least one of a galvanic skin response and skin conductivity.

7. The drug detection system of claim 1, further comprising a camera to record an image of the user'"'"'s face while the system is administering the drug detection test.

8. The drug detection system of claim 1, further comprising an integrated processing component configured to confirm the user'"'"'s identity during a sample time period and to analyze the saliva sample for the presence of drugs.

9. The drug detection system of claim 1, wherein the biometric detection surface continuously captures biometric information during two sample periods.

10. The drug detection system of claim 1, wherein the sample collection device is at least one of a strip, a vacuum pump, and a breath collection device.

11. The drug detection system of claim 1, wherein the user'"'"'s identity is confirmed based on pre-registered information for the user.

12. The drug detection system of claim 1, wherein each sample collection device is preprinted with a unique barcode for tracking during further analysis.

13. A method of administering a drug detection test comprising:

providing a self-administered tamper-evident drug detection system, the system comprising a biometric detection surface for each of a user'"'"'s right and left hands and a collection device;

requiring a user to place both the right hand and the left hand on the biometric detection surfaces and continuously capturing biometric information from each of the user'"'"'s right and left hands;

administering a drug detection test by exposing a sample collection device to the user'"'"'s mouth to collect a saliva sample while the biometric information is being continuously captured;

wherein the system invalidates the drum detection test if the biometric information is not continuously validated throughout the entire drug detection test;

wherein the collection device is provided as a replaceable cartridge with multiple sample collection devices and a single sample collection device is exposed to the user for a period of time for testing and then mechanically retracted into the collection device for analysis; and

wherein the system includes a display that guides the user as to when to release the sample collection device from the user'"'"'s mouth.

14. The method of claim 13, wherein the biometric information is biometric identification information.

15. The method of claim 14, wherein the biometric identification information includes at least one of:

a fingerprint, a handprint, and a vein pattern.

16. The method of claim 13, wherein the biometric information includes at least one of a galvanic skin response and skin conductivity.

17. The method of claim 13, further comprising recording an image of the user'"'"'s face while administering the drug detection test.

18. The method of claim 13, further comprising confirming the user'"'"'s identity during a sample time period during which the saliva sample is being collected and to analyze the saliva sample for the presence of drugs.

19. The method of claim 13, further comprising confirming that a the user is a pre-registered user.

20. The method of claim 13, wherein each sample collection device is preprinted with a unique barcode for tracking during further analysis.
