Abstract
A urine collection apparatus includes a tamper-proof, one way valve to make sure that freshly voided samples of urine are not tampered with. A chemical type thermometer is located in the reservoir to make sure that the urine sample is fresh when collected. An enzyme poison detector station helps to insure that bleach or other chemicals haven't been added to the urine to adulterate the specimen. The one way valve preferably comprises a trap door that closes as the urine sample fills up the reservoir. The presence of an adhesive substance around the edge of the trap door keeps the trap door shut after the urine sample has been collected.
Claims11
An integrity preserving and determining urine sample collection apparatus comprising:
- a reservoir having a cavity therein for collecting a sample of urine;
- a tamper-proof one way valve means attached to said reservoir and communicating with the cavity therein for permitting a sample of urine to be collected in said cavity, said one way valve means including means for substantially preventing a first sample of urine collected in said cavity from being removed from said cavity and replaced with a second sample of urine;
- and,
- a sample freshness detection means including a temperature detecting means for measuring the temperature of a sample of urine as it is being collected and for providing an indication of such a temperature for a prolonged period of time after collection of such a sample thereby serving as an indication that such a sample was fresh when collected,
- wherein said apparatus is substantially tamper proof and said temperature detecting means is located within said cavity which is only accessible to a sample through said one way valve means.
