ABSTRACT:
A cap is provided for a blood microcollection container which cap incorporates a partially open tubular and tapered scoop arrangement for engaging a puncture wound, and rapidly receiving blood from the wound. Longitudinally extending ribs serve to define and maintain a blood flow and an air venting passage in the collector, while preventing blood "hang-up" caused by capillary action in the blood flow passage of the collector. With this invention, the time of transfer is reduced substantially because less precise positioning is required of the scoop, and blood "hang-up" in the transfer passage is avoided.
