DESCRIPTION:

BRIEF SUMMARY
BACKGROUND OF THE INVENTION

This invention relates to a urine drainage device permitting training of the bladder and comprising a catheter connectable to the bladder and communicating with a collection bag.
In the treatment of patients suffering from urine incontinence it is of great importance that the normal function of the bladder be re-established if possible, e.g. subsequent to a disease which has interfered with the normal function of the bladder. If the bladder is not allowed to expand by accumulating urine, there is a great risk of the bladder being shrunk, which means tht the normal function of the bladder can never be re-established. This in turn means that the ability of the bladder to accumulate urine is almost completely lost and that the urine has to be continuously drained to a collection bag e.g. by means of a catheter.
Especially in geriatric hospital treatment, incontinence pads are widely used and recently disposable incontinent diapers as well. This treatment of the incontinent patients imposes strain on the nursing staff involved because it is necessary repeatedly to change the incontinence pads or diapers in order to achieve humane treatment of these patients. Even if the normal function of the bladder can never be re-established due to age or other reasons, it is of great importance that the accumulating ability of the bladder be maintained to relieve the strain imposed on the nursing staff, because the discharge of urine then could be fairly well controlled.
Devices of several different types for use in connection with bladder-training of incontinent patients have been suggested. The Swedish patent specification 389,803 discloses one type of such device. This device requires, as most existing devices for bladder-training do, the use of a catheter usually connected to a urine collection bag. Devices are also known which are provided with a pressure sensing system for controlling the clamping of the catheter which is clamped until a predetermined pressure is reached in the bladder/catheter, the catheter then being relieved to allow drainage of the bladder.
None of these prior art devices meets reasonable requirements concerning a simple and reliable function; they are complicated as to construction and handling.


OBJECTS OF THE INVENTION

It is a primary object of this invention to provide a urine drainage device which is extremely simple and reliable and which allows an effective bladder-training on patients confined to bed as well as other patients.
It is a further object of this invention to provide a urine drainage device for permitting automatic drainage of the bladder when a predetermined maximum pressure in the bladder has been reached.
A still further object of this invention is to provide a urine drainage device which simultaneously forms a bacteriological barrier, i.e. prevents urine back flow from the urine drainage device to the bladder.
Yet another object of this invention is to provide a urine drainage device for allowing automatic drainage of the bladder at a pre-set maximum pressure or upon accumulating a predetermined amount of urine in the bladder.
Another object of this invention is to provide a urine drainage device comprising few movable parts, the handling and using of which do not require much attention from the nursing staff and which in many cases can be operated by the patient himself.
A still further object of this invention is to provide a urine drainage device which may well be used also by patients whose normal bladder function will never be regained, the normal function of the bladder being imitated by using or maintaining the maximum capacity of the patient's bladder, i.e. the ability thereof to accumulate urine.


SUMMARY OF THE INVENTION

To achieve the foregoing objects and in accordance with the purpose of the invention, as embodied and broadly described herein, the urine drainage device according to the invention comprises a valve for controlling a connection between a catheter and a collection bag, the valve including an inlet connected to the c
