A pressure relief valve for positive pressure pump systems in which fluid is displaced from the inlet to the outlet of the pump. The pressure relief valve includes a bypass tubing member interconnecting the outlet and a lower pressure area such as the inlet. Pressure limiting means normally occlude the bypass tubing to restrict flow when the outlet pressure of the pump is below a predetermined level and responds to pressure above a predetermined level to shunt fluid from the outlet to the inlet. In the preferred embodiment, the pressure limiting means consists of bar-like members which engage the exterior of the tubing and are biased to compress the bypass tubing to a flow restricting position by elastic bands extending around the bar-like members.

Abstract:
A peristaltic pump in which fluid is displaced towards the outlet of the pump by a rotating member which engages a section of tubing. The tubing comprises an outer tubing and an inner tubing with an annular airspace maintained therebetween and vented to atmosphere. When a positive hydrostatic head is maintained above the pump head level, the inner tubing will expand and fill. When the fluid level drops below the pump head level, the inner tube collapses, closing off the tube so there is no fluid volume to displace and the pump output stops to prevent entrainment of air into the patient's circulation. An occluding valve having a normlly closed position may also be provided at the inlet to the pumping section.
