Hand-powered pumping apparatus for perfusion and other fluid catheterization procedures

摘要

A manually operated pumping apparatus which is particularly useful in catheterization procedures has two pumps supported in a housing in a parallel arrangement. The pumps are engaged by a rack and pinion actuating assembly which provides reciprocating linear movement to the two pumps during operation so that one pump performs a pumping stroke while the other pump simultaneously performs a suction stroke. The actuating assembly is driven by a drive assembly which converts rotation of a handle into linear motion usable by the rack and pinion members to drive the two pumps in their reciprocating pumping movements.
