  • Patent number: 6132407
    Abstract: An improved outlet tube device for a urinary drainage bag is disclosed wherein an outlet valve mechanism is contained with a rigid housing fixed securely to the drainage bag, rather than just being clamped to the outlet tubing, and thus cannot become separated from the bag. The outlet valve can be opened only by positive action on the part of the medical care personnel, thereby assuring that urine will be discharged only in a controlled manner. Further, because the valve mechanism does not require that a substantial length of tubing with a freely movable end be used in conjunction with the outlet port, there is no need to engage the free end of the tubing with a keeper. Thus the possibility of the tubing springing back to its straight configuration and flicking residual urine on the attending medical personnel is eliminated. In one embodiment the outlet tube device comprises a pinchcock-type valve which is fixedly mounted to the bag and which is normally operative to clamp off the outlet tube.

  • Patent number: 5019102
    Abstract: An anti-refluxive internal ureteral stent includes a ureteral catheter which is closed at its renal end and is provided with lateral perforations only in the upper and middle portions thereof. The stent includes a hood-valve at it vesical end to prevent urinary reflux. The hood-valve comprises a hood-shaped plastic foil that partially surrounds the external circumferential surface of the catheter at the oblique vesical end opening. The hood-valve is open in its resting state so as to allow the urine to flow out through the vesical outlet, unimpeded by the hood-valve, and folds over to close the vesical outlet in response to a reflux pressure generated due to a pressure differential between the catheter and the bladder. The valve remains closed until the pressure differential subsides. The urine flows into the catheter via multiple lateral openings in the upper and middle portions thereof.
