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. In a second embodiment the outlet tube device comprises a syringe-type fitting which is fixedly mounted to the bag. Depressing the syringe plunger closes the valve, and retracting the plunger opens the valve to permit fluid to be discharged through the outlet tube. In a third embodiment, a hose clamp is contained within a rigid housing and is selectively operative to clamp a hose to prevent fluid flow therethrough.
