Needle-loading multiple barrel syringe

A multiple barrel syringe for the selective dispensing of fluids, comprising:

• a body portion having a plurality of fluid-retaining bores, a plurality of individually-depressible plungers extending respectively into said bores, a single hollow needle mounted on said body portion, and fluid conduit means connecting each of said bores with the interior of said hollow needle,
• said fluid conduit means comprising a first fluid conduit communicating with each of said bores, a valve recess communicating with each first fluid conduit, and a second fluid conduit communicating at one end with said valve recess and at the other end with the interior of said hollow needle,
• a flexible valve member housed in each of said valve recesses and normally filling the interior thereof with the body of the valve member covering and sealing off the communicating ends of said first and second fluid conduits against passage of fluid upwardly through said conduits,
• and a movable seal-release member movably mounted adjacent each respective valve recess, each seal-release member having a portion projecting outwardly from the exterior of said syringe body portion and positioned to be selectively and manually actuated to move said seal release member into engagement with the valve member in said recess in a direction to engage and deform said valve member sufficiently to unseal the communicating ends of said first and second fluid conduits, whereby to permit fluid to be drawn upwardly through said needle to the bore communicating with the valve recess containing said deformed valve member, in response to withdrawal of the plunger in said bore, whereby each of said bores may be filled independently with a different fluid through the single needle.
