First Claim
Patent Images
1. A disposable patient valve for use in cardiopulmonary test apparatus comprising:
- (a) a unitary, hollow, elastomeric body, said body including at least four tubular sections, one end of each tubular section joined and sealed in a common area to the other three tubular sections to allow fluid flow from any tubular section to any other tubular section without escaping from said body, at least two of said tubular sections including zones in which said body is sufficiently elastic to close when squeezed and reopen when released; and
(b) first and second selectively actuable clamping means operatively positioned relative to said zones on said two sections to permit said elastomeric body to be inserted and removed from said clamping means when said clamping means is unactuated, the actuation of said clamping means pinching said zones to occlude fluid flow across the location being pinched.
