ABSTRACT:
A device for obtaining, transporting and dispensing a liquid specimen, has a tubular handle having a front portion and front and back ends, a body of liquid absorbent material positioned slidably in the front portion of the handle, and a rod having an end connected to the body and extending through the handle to and through the back end of the handle and having an actuating portion projecting from the back end of the handle for sliding the body forwardly to a projected position where the body is exposed beyond the front end of the handle for contact and absorption by the liquid specimen, and backwardly to a retracted position where the body is returned within the front end portion of the handle and radially enclosed by the handle for transporting the specimen, the body having substantially the same external transverse shape and dimensions as the inside transverse shape and dimensions of the front position of the handle and being substantially free from compression when slid to said retracted position, and the handle having a wall with which the body radially registers when at the retracted position and which wall is radially inwardly flexible under external pressure to radially compress the body and squeeze at least some of the absorbed liquid from the body and dispensing the specimen through the front end of the handle.
