Abstract

The utility model discloses a vacuum aspiration urinary catheterization device free from intubation, and belongs to the non-invasive catheterization technology. The vacuum aspiration urinary catheterization device is formed by connecting a vacuum pump, a urine storage bottle and a cup through a catheter. The vacuum pump pumps to enable the cup to form suction generated by negative pressure, so centrifugal expansion on urethra peripheral tissues can be generated, and the centrifugal expansion drives the urethra to enable urethra lacuna to be expanded, and then urine can flow out beneficially. An attached tremolo is used for massaging bladders or relevant acupoints to enable the bladders to retract, and therefore the urination function can be recovered. In the using process, a urethral catheter does not need to be inserted, and therefore complications like infection, pains and mucosa damage are avoided.

Description

Exempt from intubate vacuum suction o urethral catheterization device

Affiliated technical field:

This utility model relates to a kind of novel o urethral catheterization device of Noninvasive, aim to provide the various not smooth situations of urinating that are used for the treatment of acute urinary hesitancy or cause because of diseases of urinary system, Ji Kegong hospital, as emergency treatment instrument, is the urgent urethral catheterization of acute urinary hesitancy patient.During use, not needing to insert catheter, is non-invasive medical apparatus and instruments, can be operated by patient oneself or family members, as domestic auxiliary treatment apparatus and nursing materials.

Background technology:

Traditional urethral catheterization mode of centuries be by catheter through per urethram inserting bladder, the process that drains urine is called urethral catheterization.Urethral catheterization is divided into two kinds of the urethral catheterization of indwelling property and intermittent urethral catheterization.Patient keenly feels obviously owing to plugging in catheter, and especially to there being the patient of lower urinary tract partial obstruction, because catheter stimulation may be brought out urethrospasm, to cause difficult intubation even failed, and elderly men or child patient more easily occur.Catheter improper use meeting causes that injury of urethra is hemorrhage, urethral disruption, catheter air bag are broken bladder, the complication such as difficulty in decannulation.

Female perineum portion have urethral orifice variation and fold more, external genital is often with inflammation.Elder women patient is oozed urine when urethral catheterization because muscle adesmosis, muscle of perineum and sphincter of urethra are lax.Therefore, misoperation is compared with the easier secondary coli-infection of male.

No matter intermittent urethral catheterization and intubate repeatedly, or the catheter long urinary tract infection that all easily causes standing time during indwelling catheter, account for 42% of nosocomial infection according to statistics, is also that uremic one of the main reasons occurs old people.In clinical treatment work, find, intermittent urethral catheterization person's intubate 5 times is above, indwelling catheter person surpasses 14 days by urinary catheter in and almost 100% bacteriuria occurs in body, easily drives in the wrong direction and causes urinary tract infection to urinary system breeding.

Along with the arrival of aging society, the chronic urinary hesitancy that old man does not often freely cause because of acute urinary hesitancy or because urinating brings life inconvenience and painful, once cause that urinary system infection even causes uremia, has a strong impact on health and threat to life.

We are analyzed the pathogeny of diseases related, for the drawback of traditional insertion catheter urethral catheterization method for hundreds of years in the past, change the urethral catheterization mode of invasive intubate, have formed new urethral catheterization method.For clinical treatment and home care provide a kind of brand-new Therapeutic Method and instrument.

This utility model has been abandoned plug in catheter in the past and has been entered the traditional method that bladder flows out urine, but utilize negative pressure to produce suction, urethra surrounding tissue is expanded outwardly, lateral traction urethra and lacuna of Morgagni is expanded, be beneficial to urine and discharge, the captivation that negative pressure produces will be worked in coordination with bladder contraction and be made every effort to promote urine is discharged.About this utility model mechanism of action and goal of the invention are described below:

1, lacuna of Morgagni narrows down because of inflammatory congestion edema, and irriate produces spasm even can make urethra inaccessible and stop urine to be discharged.The present invention utilizes suction that negative pressure produces in external genital, makes cavernous body of penis and urethra surrounding tissue outwards be centrifugal property expansion, and further lateral traction urethra and cause lacuna of Morgagni to expand and resistance reduces, is beneficial to urine and flows out.

2, prostate and bladder neck surrounding tissue are subject to the suction affects producing because of negative pressure, cause the expansion of centrifugal property and alleviate the pressure to urethra, and its narrow lacuna is expanded, and reduce the resistance of urine stream.

3, the resistance of lacuna of Morgagni and physiology narrow reduces because internal diameter expands, and prostate and neck of bladder smooth muscle loosen alleviates spasm, so that the suction that negative pressure produces is more easily by slowly sucking-off of urine.

4, urine sucking-off can make progressively to dwindle because urinary hesitancy causes the bladder of excessive expansion that volume, wall of urinary bladder tension force reduce, smooth muscle loosening recovers contractility, under the suction combined effect producing with negative pressure, urine can be discharged smoothly, alleviate the slight illness that urinary hesitancy brings.Use this to install subsidiary tremolo simultaneously, to wall of urinary bladder and corresponding diuresis acupoint massage, impel bladder contraction and alleviate sphincteral spasm and shrink, the recovery of urinary function is played to auxiliary therapeutic action.

5, because this utility model does not need to plug in catheter, be noninvasive laser therapy measure, can avoid secondary infection.The instrumentation that this utility model is developed is easy, and patient or family members all can operate use, can be used as caring articles for use and uses at home.To the residual urine that causes because of prostate hyperplasia increase, old man urinates smooth or elderly woman urine water clock, can use the residual urine sucking-off that device of the present utility model regularly accumulates intravesical to clear, make bladder periodically emptying, can guarantee that bladder mucosa and smooth muscle have sufficient blood flow, reduce and infect, be beneficial to recovery and the reconstruction of bladder urination function.Keep often urine circulation freely to make urinary tract system clean, make to infect progressively and take a turn for the better, the recovery of urinary function, the treatment and the patient that are conducive to underlying diseases get well.

Summary of the invention:

According to the above, cause urinary hesitancy and the not smooth related factors of urinating, and the intubate urethral catheterization used of traditional treatment bring painful and inconvenient, even cause secondary urinary tract infection.We have analyzed and have caused urinary hesitancy and urinate not smooth various factors and solution, avoid as far as possible or reduce use catheter, development and design this utility model patent " exempt from intubate vacuum suction o urethral catheterization device ", for clinical and family provides a kind of medical supplies for the treatment of nursing.

The mechanism of action that the product of this utility model development " is exempted from intubate vacuum suction o urethral catheterization device " is that the suction that utilizes negative pressure to produce impels urethra peripheral tissues (male's penis and relevant connective tissue, women's pudendum and relevant connective tissue) produce centrifugal property expansion, the latter makes the passive traction of urethra cause lacuna of Morgagni expansion and is beneficial to urine outflow.Cooperation is induced bladder contraction and is recovered urinary function bladder position and relevant acupoint massage.
