Disposable male catheter system

Abstract

A disposable male catheter system includes a catheter to be inserted into the urethra of the penis. The catheter has a proximal end to discharge urine into a bag, a distal end to be inserted into the bladder and holes formed in the distal end to receive urine. A sleeve is disposed on and is harder than the catheter. The sleeve is slid along with the catheter within the urethra to a clamping region. A clamp is clamped over the penis at the clamping region to prevent urine from leaking around the catheter.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The invention relates to a disposable male catheter system which is commonly used to control male urinary incontinence that may be caused by different urinary problems, such as prostate cancer or stroke.[0003]2. Description of the Related Art[0004]Several prior art devices have been developed to control leakage or dribbling and its accompanying odor and wetness. Some of those devices include a catheter inserted into the urethra. Other catheter systems have been developed to supply medicine to the prostate and / or to withdraw fluids.[0005]U.S. Patent Application Publication No. 2005 / 0241651 discloses a clamp having clamping members lined with pads and connected by a hinge and a connection pin. U.S. Pat. No. 5,571,125 similarly relates a clamp with a cushion, a hinge and quick-release screw connection. The company Bard also produces a Cunningham Clamp having a hinged steel frame with foam rubber pads and a locking device. ...

AI Technical Summary

Benefits of technology

[0007]It is accordingly an object of the invention to provide a disposable male catheter system, which overcomes the hereinafore-mentioned disadvantages of the heretofore-known devices of this general type and which prevents leakage of urine around a catheter.

[0008]With the foregoing and other objects in view there is provided, in accordance with the invention, a disposable male catheter system, comprising a catheter configured to be inserted into the urethra of the penis, the catheter having a proximal end configured to discharged urine into a bag, a distal, possibly tapered, end configured to be inserted into the bladder and holes formed in the distal end and configured to receive urine. A sleeve, preferably having beveled ends, is disposed on and is harder than the catheter and is configured to be slid along with the catheter within the urethra to a clamping region. A clamp is configured to be clamped over the penis at the clamping region to prevent urine from leaking around the catheter. The combination of the catheter, the clamp and the hard plastic sleeve on the catheter within the penis in alignment with the clamping region, prevents any leakage of urine around the catheter.

[0009]In accordance with another feature of the invention, a stopper may be slid along the catheter up to the head of the penis when the sleeve is in the clamping region. The stopper, which is used for comfort, has ridges on an outer surface thereof aiding in manual movement and fixation of the stopper in place.

[0012]In accordance with a concomitant feature of the invention, the clamp has a living hinge, a latch to close the clamp with adjustable pressure, a rigid frame and a liner to be disposed between the rigid frame and the penis. The liner is formed of foam rubber or sponge rubber. Such features make the clamp easy to apply, adjust pressure and be quickly removable.

Problems solved by technology

However, it has been found that in actual use, such clamps may not adequately prevent leakage of urine all of the time.

Such catheter systems are either not intended to prevent urine from leaking around the catheter or do not adequately provide such prevention.
