Patent ID: 8790314

Claim:
A device for injecting a formulation, the device comprising: a needle having proximal and distal ends and a point to penetrate skin on the distal end; a hub having a diameter larger than that of the needle attached to the proximal end of the needle, wherein the hub is connected to a housing defining a chamber containing the formulation to be injected into the skin, and wherein the hub comprises a connector connecting the hub to the housing for receiving the formulation; and a polymer wrap enveloping the needle, a space being comprised between the needle and the polymer wrap; wherein the polymer wrap is tapered toward the needle along the direction toward the distal end of the polymer wrap and passes through the skin when the point is inserted into the skin, wherein the space between the needle and the polymer wrap lies in a flow path of the formulation that is injected through the space between the needle and the polymer wrap, the flow path extending between the needle and the polymer wrap through the distal end of the polymer, and wherein the housing comprises a syringe.
