Specimen collection container
First Claim
1. A specimen collection device, comprising:
- (a) a chamber for collecting a specimen;
(b) a reservoir for receiving an aliquot of specimen from the chamber and for receiving a test device;
(c) a valve functionally interposed between the chamber and the reservoir and having a compartment for holding an aliquot of specimen and transporting the aliquot from the chamber to the reservoir, the valve having first, second and third positions,whereinwhen the valve is in the first position, the valve compartment is in fluid communication with the chamber and is not in fluid communication with the reservoir;
when the valve is in the second position, the valve compartment is not in fluid communication with the chamber nor the reservoir;
when the valve is in the third position, the valve compartment is in fluid communication with the reservoir and is not in fluid communication with the chamber; and
the valve being inoperable after a first actuation.

Abstract
The present invention recognizes that sample handling devices, particularly those used for testing for substances of abuse, do not allow for a separation of the bulk sample from a sample thereof to be tested. The present invention provides such a device and methods of use. The present invention includes but is not limited to a specimen collection device that includes a chamber such that the chamber is capable of collecting a specimen. The device also includes a reservoir such that the reservoir is capable of receiving a portion of the specimen from the chamber and optionally so that the reservoir is capable of receiving a test device. The device includes a valve functionally interposed between the chamber and the reservoir that is capable of transferring at least a portion of the specimen from the chamber to the reservoir such that the chamber and the reservoir are not in direct fluid communication. The device optionally includes a means for fluidic communication between the chamber, the valve and the reservoir.

22. A method of detecting an analyte of interest in a specimen, comprising:
-
a) collecting a specimen in a test device comprising; i) a chamber for collecting and holding the specimen; ii) a reservoir for receiving an aliquot of specimen and having a test device; and iii) a valve functionally interposed between the chamber and the reservoir and having a compartment for holding the aliquot, and having a first position wherein the compartment is in fluid communication with the chamber, and a second position wherein the compartment is separated from fluid communication with both the chamber and the reservoir, wherein the valve is inoperable after a first actuation; b) causing an aliquot of specimen to enter the compartment of the valve; c) actuating the valve; d) causing the aliquot of specimen to flow out of the compartment and into the reservoir to contact the test device; and e) detecting the analyte of interest. - View Dependent Claims (23, 24, 25, 26, 27, 28)
