SAFETY VALVE FOR PREVENTING AIR EMBOLISM OR HEMORRHAGE |
摘要 |
A safety valve (10) for catheterization procedures is characterized by a piston (20) having an internal flow path, a portion of the piston (20) being surrounded by an elastomeric member (25) which surrounds a portion of the piston (20) and biases it to a closed position. The elastomeric member (25) also severely restricts fluid flow around the piston (20) to eliminate any flow path other than the internal piston (20) flow path. |
