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.

The membrane is at least partly protected by a shield. At least one vent for allowing gases to be in substantially unhindered contact with the external surface of the membrane is arranged in the catheter.

Abstract: This invention relates to a closed system specimen collection container. The collection container is designed to collect, transport and transfer the liquid specimen into a non-evacuated tube through an integrated valve component. This device has no sharp needles and utilizes a blunt cannula component on a test tube. The operation of the device consists of the steps of collecting a specimen into the container and attaching a cap in permanent locking and leak resistant attachment. The cap may be a snap-on or threaded lock. The specimen may then be immediately transported to a laboratory in the container where the specimen can be transferred into a tube for analysis. Alternatively, the specimen may then be immediately transferred into a non-evacuated tube through the integrated valve by a passive means. This technique is accomplished by inserting the blunt cannula attached to the tube into the bottom of the container and interfacing with the integrated valve component.
