ABSTRACT:
A miniature valve for use with a catheter or the like in which a cylindrical valve body is made up of a male member and female member telescoped together so as to define opposed annular seats surrounding a through-opening. A disc of rubber having a central domed portion containing an axial slit is mounted between the seats, the male and female members being detented so that the periphery of the disc is pinched thereby displacing rubber radially inwardly to keep the slit normally sealed against flow in either direction. The valve body has a female leur type connection adjacent the underside of the dome and a male leur type connection adjacent the top of the dome. The female connection is so spaced with respect to the disc that when a cooperating leur type male connector is inserted into the female connection the tip of the male connector engages the underside of the domed portion of the disc to open the slit to permit straight axial flow through the through-opening in either direction.
