ABSTRACT:
A blood sample collection kit has a syringe body, an open lumen needle, an elongated vacuum plunger for use with the syringe, and a pulling flange, a rubber sleeve covered transfer needle and screw threads at a distal end of the plunger for receiving a blood tube holder and a vacuum-type blood sample collection tube. The kit provides easy blood collection and blood transfer. The plunger body has a rubberized seal end and a flange on the opposite end. A rubber sleeve covered transfer needle is integrally formed above the flange. Screw threads connected the plunger body and a blood tube holder, which receives a vacuum-type blood sample collection tube. The vacuum plunger is inserted into a syringe and a blood tube holder is screwed onto the screw threads. A vacuum-type blood sample collection tube is inserted into the blood tube holder. Blood is obtained by manual aspiration through the access needle placed on the syringe and travels through an end-to-end tubular channel along the body of the plunger, and then is transferred to a blood sample collection tube by pushing a stopper of a vacuum-type sample collection tube against the rubber covered transfer needle, retracting the rubber covering, pushing the transfer needle through the stopper and opening the path for blood to flow into the reduced pressure in the collection tube.
