Abstract:
1. A peristaltic pump comprising: occluding surfaces rotatably supported about a common axis by a support; a first occlusion having a first occlusion surface, wherein one of the support and the first occlusion is movable towards the other of the support and the first occlusion; and a drive system configured to rotate the occluding surfaces and coupled to said one of the support and the first occlusion so as to move said one of the support and the first occlusion; and at least one bias mechanism coupled to said one of the support and the first occlusion to resiliently bias said one of the support and the first occlusion towards a non-pumping position the at least one bias mechanism being out of contact with the first occlusion surface.
