Abstract
A self-contained blood withdrawal apparatus (20) which includes a movable appendage piercing mechanism (27), a suction mechanism (30) and a specimen storage container (29). A base portion (21) is formed with a cavity opening (24) over which the appendage (10) is placed and a first passageway (25) extending from the opening to the storage container. The appendage piercing mechanism (27) is aligned with the cavity opening (24) and is movable between a retracted position and an extended appendage piercing position. Additionally, the suction mechanism (30), for facilitating withdrawal of the blood from the appendage, is coupled to the base portion (21) and communicates with the cavity opening through a second passageway (31). Accordingly, present invention provides a unitary apparatus which pierces an appendage, facilitates blood withdrawal and stores the specimen in a container.
