Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 109 words
A venogram injector assembly comprising a frame, holder means fixed to said frame and adapted to receive and retain a plurality of syringes, a manifold for disposition in said holder means and adapted to receive outlet ends of said syringes, a tube adapted for connection at a first end thereof to said manifold, a platen mounted on said assembly and movable to engage simultaneously plunger stems extending from said syringes, and drive means in communication with said platen, said platen being movable in response to operation of said drive means to engage said stems, whereby to force fluid in said syringes into said manifold and thence into said tube.
Claim 2
Dependent Claim 109 words
A venogram injector assembly comprising a frame, holder means fixed to said frame and adapted to receive and retain a plurality of syringes, a manifold for disposition in said holder means and adapted to receive outlet ends of said syringes, a tube adapted for connection at a first end thereof to said manifold, a platen mounted on said assembly and movable to engage simultaneously plunger stems extending from said syringes, and drive means in communication with said platen, said platen being movable in response to operation of said drive means to engage said stems, whereby to force fluid in said syringes into said manifold and thence into said tube.
Claim 3
Dependent Claim 44 words
The invention in accordance with claim 1 in which said manifold comprises an elongated cannister having holes therein along a side thereof for reception of said outlet ends of said syringes and having connector means at one end thereof for connection to said tube.
Claim 4
