초록 ▼

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. In one embodiment, the manifold assembly is designed to slip over the proximal ends of the cartridge retainers prior to snapping into engagement with the injector housing. In this embodiment, the manifold and cartridge containers are configured so that the manifold is able to slip over the cartridge retainers only when the cartridge retainers have been rotated into their locked positions within the injector housing.

대표청구항 ▼

A medication dispensing device for effecting the simultaneous delivery of two injectable products to a patient, comprising: a housing; a first container mounted to said housing and including a first plunger, a first exit end and a first injectable product between said first plunger and said first exit end; a second container mounted to said housing and including a second plunger, a second exit end and a second injectable product between said second plunger and said second exit end; first and second drive stems disposed in said housing and being drivingly coupled to said first and second plungers; a drive assembly mounted to said housing and drivingly coupled to said first and second drive stems to axially advance said first and second drive stems upon actuation of said drive assembly, thereby axially advancing said first and second plungers to effect delivery of first and second dosages out of said first and second containers, respectively; and a manifold secured to said exit ends of said first and second cartridges and comprising a manifold housing including a first cannula extending into said first cartridge and a second cannula extending into said second cartridge, said manifold housing including a delivery needle therein for delivery therethrough of injectable product, wherein a first fluid path for the first injectable product is formed in said manifold housing from said first cannula to said delivery needle, and a second fluid path for the second injectable product is formed in said manifold housing from said second cannula to said delivery needle, said manifold further including a pressure-actuated valve in said second fluid path, said valve being sufficiently flexible to move in a first direction to open and thereby permit the flow therethrough of the second injectable product upon the expulsion of the second injectable product out of said second cannula, said manifold including a third fluid path between said first fluid path and said valve, said third fluid path configured to divert a portion of the fluid flowing in said first fluid path to said third fluid path and onto said valve to create a fluid force on said valve in a second and opposite direction from said first direction.
