MULTI-BARREL SYRINGE INJECTION SYSTEM

摘要

An injection device for injecting a medicant into a plurality of tissue sites in a patient for a selected treatment is constructed and arranged such that the number of tissue sites is the total number for the selected treatment thereby requiring a single positioning step. The injection device includes a body having a syringe and a control linkage, the syringe including a plurality of barrels, and a cooperating plunger array including a plurality of plungers. Each barrel receives a corresponding plunger. The injection device further includes a plurality of injection needles connected to the syringe wherein one injection needle is connected to each barrel, a multi-lumen tip, a shaft connected to the multi-lumen tip and extending between said multi-lumen tip and said body. The control linkage is connected to each needle so as to move each needle between a deployed injection position and a retracted position.

1. An injection device for injecting a medicant into a plurality of sites in a patient for a selected treatment, wherein the number of sites is the total number for the selected treatment thereby requiring a single positioning step, said injection device comprising:
a body including a plurality of medicant barrels; a plurality of injection needles, wherein each needle of said plurality is connected to a corresponding one of said medicant barrels; a multi-lumen tip for positioning an open tip of each injection needle at a corresponding one of said injection sites; means for connecting said multi-lumen tip with said body; and means for moving each injection needle of said plurality of injection needles between a deployed, injection position and a retracted position, wherein the number of needles is at least as great as the number of sites for the selected treatment.
