Abstract

This invention relates to apparatus for filling medicinal syringes. The apparatus includes a pump arrangement for filling individual syringes automatically and includes a mechanical adjustment for easily changing the amount of medicinal liquid fed to each syringe. The individual syringes are then labeled with appropriate indicia showing the contents.

Claims

1. Apparatus for filling medicinal containers comprising means for holding a medicinal container upright with an opening at the top thereof, a hollow member for directing liquid into the container opening, means for holding said hollow member above the container holding means with the hollow member directed toward the opening, a supply container, plunger means in said supply container, means connecting said supply container with said hollow member, and means for moving said plunger means incremental distances further into said supply container to move amounts of liquid from the supply container through the connecting means and the hollow member when medicinal containers are to be filled.

2. Apparatus according to claim 1 characterized by means for returning said plunger means toward the initial position in said supply container after said plunger means has been moved a number of incremental distances further into said supply container.

3. Apparatus according to claim 1 characterized by said moving means comprises a gear rack connected to said plunger means, a pinion gear, and means for rotating said pinion gear in one direction only through a predetermined angle to incrementally move said plunger means each time one of the medicinal containers is to be filled.

4. Apparatus according to claim 3 characterized by said latter means includes a shaft on which said pinion gear is mounted, an arm affixed to said shaft, and adjustable means for limiting the extent of angular movement of said pinion gear.

5. Apparatus according to claim 4 characterized by a one-way clutch mounting said pinion gear on said shaft to enable said pinion gear to rotate with said shaft in only one direction effective to move said gear rack toward the supply container and said plunger means further into said supply container.

6. Apparatus according to claim 4 characterized further by drive means including an electromagnetic clutch for rotating said shaft, and means for energizing said electromagnetic clutch for a predetermined period of time when one of the medicinal containers is to be filled.

7. Apparatus according to claim 1 characterized further by means for moving said hollow member downwardly into the medicinal container when the medicinal container is held in alignment with said hollow member by said holding means.
