    摘要: A peristaltic pump (10), comprises a rotatable shaft (24) and a roller head (14) carrying a plurality of rollers (16) mounted to the shaft, adapted in use to displace fluid along a segment of a flexible fluid channel (26), wherein the speed of rotation of the rollers may be varied. An adaptive variable speed control is provided which may be configured to accelerate rotation of the pump through known minimum flow points, and to decelerate rotation of the pump through known maximum flow points responsive to a pressure sensor (126), and/or a position encoder (25), or based on a variable or pre-set pump pulsation profile.

    摘要: A surgical system having a cassette latching mechanism (10) having two pivoting latching rails (14). The rails are connected to a rotating latching wheel (16) by spring-loaded latching arms (18). The latching wheel is connected to a motor (12) by a latching pushbar (20). The cassette is pressed into the rails which initiates the rotation of the rails, which close onto the cassette. The motor next rotates the latching wheel, producing cam-like movement of the latching arms and thereby further pivoting the latching rails to the fully closed and locked position.
