DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The invention relates to the production of vesical catheters.
Such catheters are commonly used by patients to eliminate, or at least relieve, problems caused by urinary incontinence and retention.
BACKGROUND ART
Valve operated vesical catheters made of plastic material or, more generally, of synthetic resin are known.
These catheters generally consist of flexible ducts produced in various standardized lengths.
A catheter having a certain length must be chosen in accordance with the actual patients' need.
One catheter that is presently used is provided with a valve of elastic material, housed inside the duct close to the outer opening.
The valve can be operated by the patient through a slight pressure exerted from outside on a section of the penis which corresponds with the point of location of the valve.
This point can be located by the patient through a series of protuberances specially formed on the outside surface of the duct, near to the valve.
The distal end of the duct is positioned inside the bladder and has a spiral shape.
There are numerous holes provided along the terminal section of the catheter near the distal end, for urine to enter the catheter.
The principal drawback with the use of the above described catheters, results from the fact that it is difficult for the patient to locate the valve by touch, particularly as poor touch sensibility occurs in many patients who use these catheters.
A further inconvenience that has been found when such a catheter is used, results from the fact that the patient must apply pressure on the penis to operate the valve.
In the long run this, pressure that often is not light, could provoke more or less serious local traumas, with damage to the penis.
DISCLOSURE OF THE INVENTION
The main object of the present invention is to provide a catheter having a system that allows the patient to operate the valve directly and not through the penis, with a simple and safe action.
A further object of the present invention is to provide an easily adaptable catheter that can be used by any patient without causing traumas to any of the urinary system organs.
The above indicated objects are achieved by means of a valve operated catheter for urinary incontinence and retention comprising a flexible duct designed to be inserted into the patient's urethra and having a spiral shaped distal portion 12, that is designed to be housed inside the bladder.
A terminal section of the catheter, near to its distal end, is provided with a plurality of holes for the outflow of urine from the bladder to the inside of the duct.
A seat is made at an end of the catheter that remains outside the penis, the end housing a valve which is elastically deformable, the valve having a slit which is normally elastically closed.
The valve can be operated by the patient by pressing on two winglets fixed at the end of the duct, the winglets resting against the top of the glans.
In this way, deformation of the part of the duct correspondent which corresponds to the seat causes the elastic deformation of the valve until the slit opens.
The main advantage of the present invention is that it provides a catheter with a system for operating the valve that is immediately locatable by the patient, therefore, it is simple and safe to use.
The system that is the subject of this invention allows the patient to operate the valve of the catheter without pressing on the penis.
A further advantage of the present invention is that it provides a catheter of a simple construction and that it can be used by any patient without provoking traumas of any urinary system organs.
It is to be stressed that the patient does not have to press directly on the penis in any way.
The winglets remains located outside of the penis so that they can be quickly and easily located, even if the patient has poor touch sensibility.
Nevertheless the construction of the catheter is rather compact and the duct does not extend from the glans.
