Title: Self-sealing check valve
Inventor: BELL CRAIG JAMES
IPC: A61F2/958
Filed: 1985-06-12
Abstract: A self-sealing check valve 20, for use in the inflation of a catheter cuff, includes a valve housing 22 and a valve element 28 sealingly positioned within the housing. The valve housing has a transversely located fitting 32 for receiving a Luer tip device. The valve element is cylindrical and preferably hollow. A circumferential rim 30 at each end of the element is maintained in a state of compression so that it presses against the inner wall of the housing to form a seal. The element also includes a circumferential channel 34 which is aligned with the Luer fitting. Insertion of the Luer tip device into the fitting depresses the valve element and breaks the seal between the rims and the valve housing wall. This allows fluid flow in either direction through the valve. Resiliency of the valve element causes resealment at the rims when the Luer tip device is removed. <IMAGE>

Engagement of cam follower (36) with cam (37 or 38) on the feed path causes the grippers (17, 17) to open to grip or release the stringers (13, 14). Grippers (17, 17) are normally urged by spring (39) to clamp stringers (13, 14). Pinion (43) is angularly movably supported on slide block (42) in the housing (26) and held in mesh with racks (40, 41) of the sliders (23, 28). A spring (39) acts between the housing (26) and the slide block (42) for normally urging the slide block (42) in a direction to move the gripper holders (15, 16) into abutment against the housing (26). The gripper holders (15, 16) can be moved relatively to each other toward and away from the housing (26). <IMAGE>
