Abstract: A drain valve is disclosed which is adapted to be attached to the frame of a wheelchair, bed, or other object for draining a catheter reservoir bag without any part of the reservoir bag contents coming in contact with the valve. The valve has an integral spring-loaded plunger which pinches closed the drain tubing of the reservoir bag. The plunger is connected through a flexible cable to a control device. The valve is normally closed pinching closed the drain tubing, and the reservoir bag is filled through the inlet tubing attached to the patient. When the reservoir bag is to be drained, the control device is activated by the patient to retract the spring-loaded plunger in the valve opening the drain tubing and allowing the reservoir bag to darin. In one embodiment, the control device is a remotely operated hand lever mechanism connected to the cable. In another embodiment, the control device is a solenoid operator connected to the cable.
