摘要： 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.

摘要： 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.
