Abstract:

A blood collection device includes a syringe assembly containing a slidable needle assembly within the cavity of a syringe body. The syringe body has a syringe top for receiving a seal assembly wherein the seal assembly is reversibly locked to the top of the syringe top. Within the insertable tube of the seal assembly is an occluding seal secured within the insertable cylinder with retaining rings. The occluding seal allows blood to flow from on end of a double pointed needle into a fully inserted collection tube. When the collection tube is removed the occluding seal keeps blood from flowing into the cavity of the insertable cylinder.

US Classification:

Abstract:

A reusable hypodermic syringe assembly (200) comprising a syringe (218) having a barrel shaped portion (214) with an opening (280) therein, a cartridge (202) insertable into and removable from the barrel shaped portion (214) of the syringe and containing a medication (262) into a patient from the cartridge (202) with the needle (210) and the medication (262) being sealably contained within first (204) and second (260) separately sealed compartments, respectively, within the cartridge (202) before injection of the medication. A plunger (224) functions to push on the second compartment (204) and thereby extends the distal end of the needle (210) out of the cartridge (202) and the proximal end of the needle (213) into the sealed second compartment (204) containing the medication before the injection of the medication (262), without the needle (210) being touched by human hands. The plunger (224) retracts the needle (210) completely back inside the cartridge (202), again without the needle (210) being touched by human hands and further releases the plunger (224) from the second compartment (204) to enable removal of the cartridge (202) from the barrel shaped portion (214) of the syringe to thereby enable the insertion of a fresh cartridge (202) into the barrel shaped portion (214) of the syringe in preparation for the next injection.
