Abstract
A multiple barrel syringe for selective delivery of a plurality of fluids through a single needle is adapted to be loaded with each of said fluids through the needle thereof. The syringe body includes a pair of fluid-retaining bores, each containing a plunger and each communicating with the single needle through restrictive conduits in which respective flexible sealing valves are interposed. As each plunger is depressed, the respective valve is depressed and distorts under pressure of the fluid, allowing the fluid to flow to the needle. For filling each bore through the needle, a plunger is manually depressed to compress and distort the respective valve, enabling fluid to flow from a container through the needle and through the unobstructed conduit to the selected bore in response to raising of the plunger.
