Abstract
Abstract A syringe filling apparatus consisting of an upright frame having a platform for supporting a tray adapted to hold a plurality of syringe cartridges in either a horizontal storage or vertical filling position, there being provided below the platform a manually operated squeeze bubble defining a pump for pressurizing a removable medicament unit. The medicament unit includes a flexible outlet tube from a disposable medicament bottle having a nozzle at the end of the tube. A pinch-type handle valve is fixed to the end of the flexible outlet tube adjacent the nozzle that may be manually grasped and actuated to fill each of the cartridges supported on the tray on the work supporting platform.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
232 words
A medicament receptacle filling apparatus, comprising: frame means having front and back sides, and a lower end for supporting the frame means in a generally vertical position, a generally horizontal receptacle supporting platform on said frame means at the front side thereof for supporting a plurality of medicament receiving receptacles, a medicament supply container removably supported on said frame means in an inverted position above said receptacle supporting platform, manually operable pump means supported on said frame means for pressurizing the supply container, air conduit means connected between said pump means and the interior of said supply container, a filter connected in fluid flow communication with said air conduit means between said pump means and said supply container, whereby manual operation of said pump means pressurizes said supply container with positive pressure filtered air, flexible delivery conduit means extending from said supply container, said flexible delivery conduit means having a discharge nozzle at the free end thereof, and a manually operable pinch valve detachably carried on the free end of the flexible conduit means, said pinch valve normally preventing flow of medicament through said delivery conduit means but being manually operable to permit said flow to initiate the flow of medicament selectively to each of said medicament receiving receptacles and to stop the flow of medicament to each medicament receiving receptacle to control the level of medicament in each medicament receiving receptacle.
Claim 2
Dependent Claim
232 words
A medicament receptacle filling apparatus, comprising: frame means having front and back sides, and a lower end for supporting the frame means in a generally vertical position, a generally horizontal receptacle supporting platform on said frame means at the front side thereof for supporting a plurality of medicament receiving receptacles, a medicament supply container removably supported on said frame means in an inverted position above said receptacle supporting platform, manually operable pump means supported on said frame means for pressurizing the supply container, air conduit means connected between said pump means and the interior of said supply container, a filter connected in fluid flow communication with said air conduit means between said pump means and said supply container, whereby manual operation of said pump means pressurizes said supply container with positive pressure filtered air, flexible delivery conduit means extending from said supply container, said flexible delivery conduit means having a discharge nozzle at the free end thereof, and a manually operable pinch valve detachably carried on the free end of the flexible conduit means, said pinch valve normally preventing flow of medicament through said delivery conduit means but being manually operable to permit said flow to initiate the flow of medicament selectively to each of said medicament receiving receptacles and to stop the flow of medicament to each medicament receiving receptacle to control the level of medicament in each medicament receiving receptacle.
Claim 3
Dependent Claim
63 words
A medicament receptacle filling apparatus as defined in claim 1 wherein said pump means has first means thereon communicating with the atmosphere for supplying air into said pump means, and second means on said pump means connected in fluid communication with said air conduit means to pump air from the atmosphere into the supply container for pressurizing the supply container with positive pressure.
Claim 4
Dependent Claim
49 words
A medicament receptacle filling apparatus as defined in claim 2 wherein said pump means comprises a squeeze bulb, and said platform includes a tray thereon for holding a plurality of said receptacles, said tray including means for frictionally holding the receptacles selectively in horizontal storage and vertical filling positions.
Claim 5
Dependent Claim
73 words
A medicament receptacle filling apparatus as defined in claim 2 further including a fitting connected to said frame means, and wherein said air conduit means includes a pair of conduits respectively connected in fluid communication with said supply container and said pump means, said fitting connecting said pair of conduits in fluid communication with each other, and said filter means being connected within said fitting to filter air flowing to said supply container.
