Abstract: A multi-cartridge dispenser for delivering two liquid medications through a single needle. The dispenser includes independent dual channel metering mechanism, dual channel drive mechanisms, and dual channel lock and pullback mechanisms. The wing must be in its "up" position for metering to take place. The wing reciprocatingly moves a driver between a pre-injection position and a post-injection position to reciprocatingly advance the leadscrews upon an injection stroke. The dosage indicator automatically rotates to its initial zero position upon the injection stroke. The lock and pullback mechanism automatically prevents rotation of the leadscrew upon metering and injection. It also locks out the cartridge retainers so that the retainers can be removed from the housing only while the wing is in its "down" position. The pullback sleeve unloads a pullback key during a cartridge change in order to enable the leadscrew to be spun freely back to its home position.

Abstract: A hand-held dual liquid medication injector have dual, bi-directional dosage metering mechanisms for permitting a variable dosage amount for each cartridge of liquid medication. The medications are mixed within a manifold having a valved mixing chamber and are injected via a single cannula. The mixing chamber is valved such that backflow of mixed or unmixed medications into the cartridges is prevented. An injection mechanism, independent of the metering mechanism, loads and injects the liquid medication. In one embodiment, downward movement of the injection mechanism during injection is translated into horizontal movement by the plunger mechanism. In another embodiment, a power-assisted plunger mechanism accomplishes injection.

Abstract: A removable manifold assembly for attachment to the outlet end of a multi-cartridge injection device. The manifold assembly comprises two rigid plastic housings which encapsulate a rubber septum. Check valves are formed by compressing the front surface of the septum against a seal face of the rear housing to form a fluid tight interface therebetween. A first fluid path is formed from each cartridge in the injector through the manifold assembly to a patient delivery needle. A second fluid path is formed in the manifold assembly from the first fluid path to a back surface of the septum in order to enable a residual fluid force to be exerted against the back surface of the septum, thereby forcing the respective check valve in its closed position. The manifold assembly includes a unique geometry that permits the manifold to be snapped into engagement with the housing only when properly oriented with the housing.

Abstract: A disposable hypodermic needle is disclosed, including a conventional hollow needle having a sharp distal end and a plastic, integrally formed closure means, including a shank mounted on the distal end, plastic wings for enclosing the distal end for disposal of the needle. The wings include interlocking means to make the closure permanent, and include hinges for allowing the wings to be manipulated relative to the shank. Grips are provided on the wings for safe handling of the hypodermic needle. A sheath is provided for the distal end of the needle for maintaining its sterility and preventing accidental injury to the practitioner. In one embodiment, a lock hub is provided at one end of the shank to allow connection to a catheter, and in another embodiment, a tube is provided between the shank and the lock hub.
