First Claim
1. A device for collecting and storing a fluid, and applying an aliquot of the fluid to a test device, comprising:
- a. a sample collector having an absorbent member, configured to collect a liquid sample;
b. a receiving member, configured to receive said sample collector;
c. an expression member, configured to express the collected sample from said absorbent member being manually pressed into the expression member;
d. a reservoir, configured to receive the expressed sample from said sample collector, wherein a portion of said reservoir is flexible, and;

Abstract
The present invention is a device for conveniently collecting and storing liquid samples, as well as applying an aliquot of the sample to a test device, such as a lateral flow immunoassay. The present invention comprises an absorbent swab and a dropper container containing an expression means for expressing the collected sample from the swab. After the collected sample has been expressed into the reservoir of the device, the device is capped. The device can be inverted over a test device, the sides of the reservoir squeezed and an aliquot of the sample applied, in a drop-wise manner, to the sample application well of the test device. The present invention is particularly useful for collecting viscous samples, such as saliva or oral fluid, in a drug of abuse testing setting.
