ABSTRACT:
The device for collecting blood specimens by venipuncture for laboratory tests consists of a hollow support fitted with a double-ended needle at one end and a vial with a plunger that can be fitted into and removed from the cavity in the support, the vial being sealed at one end by a pierceable membrane. In a preferred embodiment a mechanical system for automatic operation of the plunger is also envisaged. The double-ended needle consists of an active needle that enters the vein, positioned eccentrically to the axis of the support, and a passive needle that punctures the vial membrane eccentrically.
