Abstract
Sterile urine specimen collection is achieved by collecting the initial or forestream portion of a void in a chamber and then directing the midstream overflow into a specimen container in which the chamber is partially disposed. Overflow from the specimen container is drained to ambient or to an overflow container. This specimen container is selectively disengageable from the apparatus and can be sealed with a sterile cap which is secured to the apparatus in a sterile manner before it is deployed on the specimen container. Collection of the forestream and terminal portions of the void eliminates dripping from the unit when the specimen container is removed. When the terminal portion is drained to ambient, the drain tube is provided with a drip prevention structure. Void urine is received in a funnel having an oval entrance and a discharge spout which projects into the forestream chamber to a level above overflow holes defined in the chamber. A urine-absorbent material is disposed in the forestream chamber to immobilize the collected forestream and thereby minimize intermixing of the collected forestream with the overflowing midstream.
