ABSTRACT:
The present invention provides a pumping chamber to be constructed as follows:
A collapsible tubing is attached to an inlet fitting and to and outlet fitting to transport a biologic fluid such as blood therethrough. An outer tubing surrounds the collapsible tubing and is secured to the outer surface of the inlet fitting and to the outer surface of the outlet fitting, forming a chamber thereby. At least a duality of ports defining passageways through the wall of the outer tubing permits communication of the chamber with ambient conditions outside the chamber. The ports are designed to accept such devices as pressure gauges, alarm systems and devices to regulate intrachamber pressure, to observe arterial pressure, and to regulate collapse and occlusion of collapsible tubing in response to inadequate blood volumes.
