Abstract
A modular infusion pump system utilizes a positive displacement pump for pumping a known quantity of fluid for each stroke. A plurality of longitudinally spaced apart fixed combs cooperate with a resilient tube to define a known pumping volume. A plurality of movable combs are interdigitated with the fixed combs and are periodically linearly directed to cause the pump volume to be compressed, and therefore the fluid expelled. A rotary to linear drive system is connected with the movable combs and a ratchet system prevents counterrotation when the motor is in the off position. Valves are disposed above and below the pumping unit to appropriately seal off the pumping volume. The valves and the movable combs are operated by means of cams carried by a common shaft.
