  • Patent number: 5171230
    Abstract: A fast flush catheter valve is disclosed having a valve body with a longitudinal bore therethrough for the flow of fluids through the valve. A tube is mounted substantially transverse to the longitudinal bore to substantially block the longitudinal bore. An actuating member is mounted through the exterior of the valve body so that one end of the actuating member is proximate the tube and the second end extends beyond the exterior of the valve body. A resilient biasing flange connects the second end of the actuating member to the exterior of the valve body. A capillary is mounted through the tube to provide a drip rate flow. Depressing the second end of the actuating member deforms the tube to produce a flush rate around the tube and releasing the second end causes the resilient flange to return the actuating member to a position where the tube can elastically return to the longitudinal bore blocking position. The valve is constructed from a few components and is simply and inexpensively constructed.

  • Patent number: 4743235
    Abstract: A device for controlling the flow of liquid to a catheter. Two end caps support a capillary tube that provides continuous flow of liquid from one end cap to the other. A flexible, resilient sleeve is connected at its ends to said end caps and surrounds said capillary tube. Said sleeve, when pulled away from said capillary tube, provides an alternate high flow volume flow from one end cap to the other outside of the tube.
