DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a urinary incontinence device.
Urinary incontinence in the aged population is an enormous problem. Approximately 50% of the patients residing in nursing homes were placed there because of problems with urinary incontinence. It is estimated that there are 20 million incontinent patients in the United States alone, and that only 10% of these people ever seek medical assistance. Sufferers from this condition can become social hermits because of the fear of accidents due to sudden loss of urine and the embarrassment associated with urine odours. Most patients have been convinced that incontinence is a natural aging phenomenon and many wear protective padding. This arrangement is extremely primitive and demeaning for the patients.
The majority of urinary incontinence occurs in the female. Recently there has been an increase in post prostatectomy incontinence, since radical prostate surgery has increased dramatically in the last five years.
A distinction must be made as to whether the problem occurs in an active healthy person or in someone who is institutionalized in either a chronic care facility or in a nursing home. The treatment approaches will necessarily be different. In the case of the institutionalized person suffering from urinary incontinence, they are often unable to have any surgical procedure to correct their condition so that non-invasive (non-surgical) approaches are required. The common practice in most nursing homes at present is to have the patients fitted with an absorbent diaper-like material. These antiquated arrangements account for the malodorous environment found in nursing homes as well as the high incidence of local skin problems due to the constant exposure to urine. For various reasons, most nursing homes will not accept patients with catheters.
Many devices have been designed to deal with the problem of urinary leakage and the various difficulties associated with the use of these devices are well known. The basic problem found in many of the females with urinary incontinence is that there is a descent of the bladder neck and an associated wide open bladder neck and upper third of urethra, the so-called funnel-shaped urethra. To correct the incontinence without surgery, one must have a device which either occludes the urethra or elevates the bladder neck and occludes the upper 1/2 of the urethra. Many of the proposed devices are designed to be placed in the vagina but retaining the device has been one of the main problems associated with their use. In an effort to increase the obstruction to the flow of urine, various other techniques have been used. More recently periurethral injections with various compounds have been used. The purpose of these injections is to obliterate the lumen of the urethra and thus reduce the urinary incontinence. Some of the substances injected include periurethral Teflon, injections of collagen and more recently periurethral injections of autogous fat. In some instances, urethral catheterization has been used to control incontinence. This carries a risk of significant infection. More recently, there have been various urethral plugs designed for inserting in the urethra to occlude the lumen. These plugs are disposable and have to be re-inserted after each voiding. Some of the plugs are retained by means of a balloon arrangements and these all carry the risk of urethral irritation and infection.
In summary, females are incontinent of urine for several reasons and there are various classifications of the problem. As a general observation, the condition can be controlled by several non-surgical approaches. One can insert a urethral plug to retain the urine or a device can be used to elevate the bladder neck and occlude the upper half of the urethra. This will restore continence in most instances.
In German Patent Application No. 3139811, there is described a device in which a magnetic plate is surgically attached to the pubic bone. A tampon containing a magnet is inserted into the vagina and it is intended that the magnetic for
