  • Patent number: 5674206
    Abstract: A medical intravenous injection site is provided having a single piece elastomeric septum and valve combination element. The septum has a slit therein, through which a blunt cannula or a male luer slip or male luer taper can be inserted. A valve element is suspended below the septum by straps extending between the septum and valve element, and formed integrally with them as a single, one-piece elastomeric septum, valve, and strap structure. When the blunt cannula is inserted through the slit in the septum, the valve portion will be displaced away from the septum portion, and away from a valve seat formed in the interior of a substantially rigid housing in which the septum and valve structure is mounted. Fluid communication, in either direction past the valve seat, may therefore be established. Because the septum is mounted across the end of the rigid housing, it is wipeable.

  • Patent number: 5207641
    Abstract: A dual purpose catheter valve especially for oxygen insufflation and mucous suction from the lungs and trachea system of a patient, is provided. The body has two snap-fitted generally cylindrical parts, mounted for relative rotation, with an oxygen port, suction port and catheter port on the outer body part for connection to the respective valves, and ports formed in the wall of the inner body part. There are two pairs of inner body ports, one pair for alignment with the oxygen port and the catheter port of the outer body part, the other pair for alignment with the suction port and the catheter port of the outer body part. When one of the oxygen or suction ports is aligned for fluid communication to the interior of the body and to the catheter port, the other of the oxygen or suction ports is shut off by a wall portion of the inner body part.
