ABSTRACT:
A multiple barrel syringe for selective delivery of fluids which comprises a body having a pair of bores each containing a plunger and each terminating in a smaller sized conduit for receiving fluid from the bores. Connected to the body is a movable member having a single conduit or passage and a needle mounted on the member and communicating with the bore. The movable member may be manually actuated to bring its single conduit into communication with a selected bore conduit for providing passage of fluid from the selected bore to the needle. The movable member may then be moved to another position to bring the needle into communication with the other bore. Sealing means are provided on the movable member to avoid leakage and feedback of fluid from or to the bore not dispensing fluid.
