Abstract
The invention discloses an intubation-free negative pressure suction urethral catheterization device in the intubation-free urethral catheterization technology. The device is composed of a vacuum pump, a urine storage bottle and a covering cup, which are connected through ducts. The vacuum pump promotes urethral peripheral tissues to generate centrifugal expansion through suction force generated by the covering cup when forming negative pressure, and the covering cup generates urethral passive traction to expand the urethral lacuna to facilitate outflow of urine. An additional vibration massager massages the bladder part and related acupuncture points to induce bladder contraction so as to recover the urinary function. When not in use, no catheter is needed to be inserted to avoid infection, pain and such complications as mucosa damage, etc.
Description
Affiliated technical field:
The present invention 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, can, for hospital as the emergency treatment instrument, be both the urgent urethral catheterization of acute urinary hesitancy patient.Not needing to insert catheter during use, is non-invasive medical apparatus and instruments, can be by patient oneself or family members' operation, 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 the patient of lower urinary tract partial obstruction is arranged, because the 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 section have urethral orifice variation and fold more, external genital is often with inflammation.The elder women patient is oozed urine when urethral catheterization because muscle adesmosis, muscle of perineum and sphincter of urethra are lax.Therefore, misoperation is than 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 the old people.In clinical treatment work, find, intermittent urethral catheterization person's intubate more than 5 times, indwelling catheter person surpass 14 days by urinary catheter in and almost 100% bacteriuria occur in body, easily drive in the wrong direction and cause urinary tract infection to the urinary system breeding.
Along with the arrival of aging society, the chronic urinary hesitancy that the 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.
The present invention has abandoned plug in catheter in the past and has entered the traditional method that bladder flows out urine, but utilize negative pressure to produce suction, the urethra surrounding tissue is expanded outwardly, lateral traction urethra and lacuna of Morgagni is enlarged, 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 the mechanism of action of the present invention and goal of the invention are described below:
1, lacuna of Morgagni narrows down because of the inflammatory congestion edema, and irriate produces spasm and even can make the urethra obturation and stop urine to be discharged.The suction that the present invention utilizes negative pressure to produce, in external genital, makes cavernous body of penis and urethra surrounding tissue outwards be the expansion of centrifugal property, and further lateral traction urethra and cause lacuna of Morgagni to enlarge and resistance reduces, be beneficial to urine and flow out.
2, prostate and bladder neck surrounding tissue are subject to the suction affects produced because of negative pressure, cause the expansion of centrifugal property and alleviate the pressure to urethra, and its narrow lacuna is enlarged, and reduce the resistance of urine stream.
3, the resistance of lacuna of Morgagni and physiology narrow reduces because internal diameter enlarges, 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, the 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 produced 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 the present invention does not need to plug in catheter, be the noninvasive laser therapy measure, can avoid secondary infection.The instrumentation that the present invention develops is easy, and patient or family members all can operate use, can be used as the caring articles for use and uses at home.To the residual urine that causes because of prostate hyperplasia increase, the old man urinates smooth or elderly woman urine water clock, can use the residual urine sucking-off that device of the present invention 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:
Cause urinary hesitancy and the not smooth related factors of urinating according to the above, and the intubate urethral catheterization used of traditional treatment bring painful and inconvenient, even cause the 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 the use catheter, development and design patent of the present invention " 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 the present invention's 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 the expansion of centrifugal property, the latter makes the passive traction of urethra cause lacuna of Morgagni expansion and is beneficial to the urine outflow.Cooperation is induced bladder contraction and is recovered urinary function bladder position and relevant acupoint massage.
