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.

Claims

1. A catheter assembly and control valve therefor comprising:

a reservoir bas having an inlet end and a single flexible drain tube for draining the contents thereof,

a catheter tube having one end for insertion into a human body orifice and its other end connected to said bag inlet end,

a drain valve connected to said single bag drain tube for controlling flow of the contents from said bag,

said valve being connected with said single bag drain tube such that no part of the bag contents contact said valve,

said valve having a housing with openings through which said single flexible drain tube extends,

a valve plunger slidably positioned in said valve housing and operable to move longitudinally therein,

a spring positioned in said valve housing to urge said valve plunger toward an extended position to pinch closed said single drain tube for filling said reservoir bag,

control means operatively connected to said valve plunger for moving said plunger between a normally extended position pinching said single drain tube closed and a retracted position opening said drain tube and allowing the contents of said reservoir bag to drain therethrough, and

said bag and valve being adapted to be secured adjacent to the catheterized body.

2. A catheter assembly and control valve according to claim 1 in which;

said control means comprises a lever mechanism remote from said valve housing, and

a length flexible cable having one end connected to said plunger and its other end connected to said lever mechanism, whereby

operation of said lever mechanism retracts said plunger for opening said single drain tube.

3. A catheter assembly and control valve according to claim 1 in which;

said drain valve housing comprises a tubular member,

a base cap enclosing one end of said tubular member,

an end cap enclosing the opposite end of said tubular member,

apertures in the side wall of said tubular member axially aligned for receiving said single drain tube therethrough and disposed to position said single drain tube between said base cap and said valve plunger.

4. A catheter assembly and control valve according to claim 3 in which

said end cap has cable connection means at one end for receiving and adjustably securing one end of a flexible cable thereto.

5. A catheter assembly and control valve according to claim 3 in which

said base cap and said valve plunger having opposite facing ends configured to cooperatively engage said single drain tube such that it is maintained pinched closed when said valve plunger is in said extended position.

6. A catheter assembly and control valve according to claim 5 in which;

said base cap and said valve plunger opposite facing ends comprise congruous curved surfaces, whereby

a portion of said single drain tube is received therebetween and is pinched closed when said valve plunger is moved to said extended position.

7. A catheter assembly and control valve according to claim 6 in which

said valve plunger has a convex spherical forward end engageable with said single drain tube.

8. A catheter assembly and control valve according to claim 6 in which

said base cap has a concave spherical end engageable with said single drain tube.

9. A catheter assembly and control valve according to claim 6 in which;

said valve plunger has a convex spherical forward end engageable with said drain tube, and

said base cap has a concave spherical end engageable with said single drain tube.
