ABSTRACT:
A liquid specimen collection device includes a main body provided with a passage extending between opposite ends of the main body that defines a capillary tube liquid specimen flow path. One end of the passage opens at a tip end of the body member that is positionable adjacent a liquid specimen for introducing the liquid specimen into the passage while the opposite end of the passage opens at a body surface of the body which surrounds and extends outwardly from the opposite end of the passage. A test paper soaked in reagent is secured to the main body adjacent the opposite end of the passage. A liquid sample introduced into the passage at the tip end of the body member flows by capillary action along the passage to the opposite end of the passage where the specimen is then absorbed by the test paper. The test paper is secured to the body member at a plurality of spaced apart securement locations along a peripheral portion of the test paper with gaps being located between adjacent securement locations through which air is permitted to flow during liquid specimen flow along the liquid specimen flow path. The test paper includes a centrally located protuberance and an annular protuberance extending around the outer circumferential portion of the test paper. The end surface of the tip end of the body member can be provided with a groove extending between the outer peripheral surface of the tip end and the passage in the body member.
