Abstract
A hemostasis valve comprising a body having a central passage, a seal having a central aperature therein, the seal being mounted in the central passage, and a diaphragm having a wall member with a slit therein, the diaphragm being mounted in the central passage, the diaphragm wall member having an inner bottom diaphragm surface, and an outer bottom diaphragm surface, the slit extending from the inner bottom diaphragm surface to the outer bottom diaphragm surface, the wall member having a diaphragm chamber therewithin.
Claims10
A hemostasis valve comprising:
- (a) a body having a central passage therein;
- (b) a seal having a central aperture therein, said seal being mounted in said central passage;
- and
- (c) a resilient, dome shaped diaphragm having a wall member with a single, linear slit therein, said diaphragm being mounted in said central passage, said diaphragm wall member having an inner bottom diaphragm surface, and an outer bottom diaphragm surface, said slit extending through said wall member from said inner bottom diaphragm surface to said outer bottom diaphragm surface, said wall member defining with said seal a diaphragm chamber within the space between said inner bottom diaphragm surface and said seal, whereby the side walls of said dome shaped diaphragm will act in cooperation with the walls of said central passage to resiliently urge said slit closed when no catheter is present therethrough.
In a hemostasis valve comprising a body and a diaphragm having a wall member with a slit therein, said body having a central passage, the improvement wherein said valve comprises fast release connector means.
A diaphragm for a self-sealing valve comprising a piece of resilient material having a dome shaped wall member, said wall member having an inner bottom surface, and an outer bottom surface, there being a single, linear slit extending through said wall member from said inner bottom surface to said outer bottom surface, said diaphragm further comprising a pair of elongated ribs on said outer bottom surface, said ribs being perpendicular to said elongated slit, whereby the resilience of said ribs acts to close said slit.
