Abstract
A blood collector system utilizes a standard disposable needle assembly and standard blood collecting and receiving tubes of the type sealed by a pierceable septum. The system has a hollow cylinder, including an internally apertured sleeve into which the needle assembly is mounted and into which the sealed blood collecting tubes are inserted to be pierced by a needle of the needle assembly. A member, such as a plate, is pivotably mounted to the cylinder. A hole in the plate accommodates the needle assembly while the needle assembly is retained in the cylinder. When the blood specimen collection is complete, the plate is moved in a pivoting motion whereby it catches the needle assembly and ejects it from the cylinder. The apparatus of the invention eliminates the need for a protective sheath to be replaced on the needle assembly before the needle assembly is discarded, and thereby minimizes the health care worker's exposure to accidental needle pricks.
