PERISTALTIC PUMP WITH AIR VENTING

摘要

A peristaltic pump 10 for use in ophthalmic surgery includes a housing 12 , a pump head 14 having plurality of rollers 16 , a backing plate 18 attached to the housing 12 , and a length of surgical tubing 50 . The rollers 16 and backing plate 18 cooperate to pinch the length of surgical tubing 50 to peristaltically pump fluids from a surgical site to a collection bag 64 . At least one of the pump head 14 and the backing plate 18 is moveable, during operation of the pump 10 , from a tubing pinched position to a tubing vent position. This movement allows the tubing 50 to be vented by removing the pinched closure of the tubing 50.
