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.

A miniature valve for use with a catheter or the like comprising a cylindrical valve body made up of a cylindrical male member and a cylindrical female member telescoped together, the members having respective internal annular seats opposed to one another and surrounding a central through-opening, the valve body having leur-type tapered male and female connections at the respective ends communicating with the through-opening, a disc of soft rubber having a diameter which snugly fills the space between the seats, the disc having a central domed portion of shallow dome shape and with a central axial slit, the axial dimension of the peripheral portion of the disc in the relaxed state being substantially greater than the average thickness of the domed portion, the male and female members having axially interengaging detent elements so positioned that when the members are detented together the peripheral portion of the rubber disc is tightly pinched between the seats accompanied by a radially inward displacement of rubber to stress the domed portion of the disc in radial compression thereby to keep the slit normally sealed against flow of fluid in either direction, the leur-type female connection being axially aligned with the disc and adjacent the concave side of the domed portion thereof and so spaced with respect thereto that when a cooperating leur-type male connector is inserted into the female connection and pressed into tight seated condition, the tip of the male connection sealingly engages the domed portion of the disc to bow the same outwardly accompanied by spreading of the slit but short of axial penetration thereby to permit axial flow of fluid through the through-opening.
