Abstract
A peristaltic pump 30 includes a 360° backing plate 14 and 35 and an orbiter 36 for eccentrically orbiting within the backing plate. A loop of tubing 16 surrounds the orbiter 36 and is placed between the orbiter 36 and the backing plate.
Claims10
A peristaltic pump comprising:
- a 360° backing plate;
- an orbiter for eccentrically orbiting within the backing plate;
- a loop of tubing surrounding the orbiter and placed between the orbiter and the backing plate, the tubing having an inlet and an outlet;
- wherein upon activation of the orbiter, one region of the loop of tubing will be pinched between the orbiter and the backing plate such that the loop of tubing remains pinched at all times during the eccentric orbit of the orbiter within the backing plate;
- and
- thereby causing fluid to be pumped from the inlet to the outlet.
3 more elements
A pump cartridge comprising;
- a cartridge housing wherein a portion of the housing forms at least a portion of a backing plate for a pump and is structured to be attached to the pump;
- at least a 360° loop of tubing;
- and
- wherein the backing plate portion retains and surrounds at least a portion of the loop of tubing.
1 more element
A peristaltic pump comprising:
- a housing;
- a 360° backing plate formed in the housing;
- an orbiter for eccentrically orbiting within the backing plate;
- and
- wherein upon activation of the orbiter, one region of a loop of tubing surrounding the orbiter will be pinched between the orbiter and the backing plate at all times during the orbit of the orbiter.
2 more elements
A pump cartridge comprising:
- a cartridge housing including structure forming a backing plate for a pump;
- attachment means for attaching the cartridge to the pump;
- and
- at least a 360° loop of tubing surrounded by and adjacent to the backing place.
