Description

Intubation-free negative pressure suction urethral catheterization device

Art:

The present invention relates to the novel o urethral catheterization device of a kind of Noninvasive, it is desirable to provide be used for treating acute urinary hesitancy or because of The various the most smooth situations of urinating that diseases of urinary system causes, had both been available for hospital as emergency treatment instrument, for acute urinary hesitancy The urgent urethral catheterization of patient.It is not required to during use insert catheter, for non-invasive medical apparatus and instruments, can be operated by patient oneself or family members, make For domestic auxiliary therapeutic apparatus tool and nursing materials.

Background technology:

Traditional urethral catheterization mode of centuries is through per urethram inserting bladder by catheter, drain the process of urine Do urethral catheterization.Urethral catheterization is divided into indwelling urethral catheterization and intermittent urethral catheterization two kinds.Owing to during plug in catheter, patient keenly feels substantially, especially to having The patient of lower urinary tract partial obstruction, may cause difficult intubation even unsuccessfully by induction urethrospasm because catheter stimulates, elderly men Or child patient is easier to occur.Catheter improper use can cause that injury of urethra is hemorrhage, urethral disruption, catheter air bag are broken Bladder, the complication such as difficulty in decannulation.

Female perineum portion has urethral orifice variation and fold more, and external genital is often accompanied by inflammation.Elder women patient is due to flesh Meat adesmosis, muscle of perineum and sphincter of urethra are lax and ooze urine when urethral catheterization.Therefore, misoperation is maleer Property is more easy to secondary coli-infection.

No matter intermittent urethral catheterization and repeatedly intubate, or during indwelling catheter catheter standing time long the most easily cause urinary tract Infect, account for the 42% of nosocomial infection according to statistics, be also that old people occurs uremic one of the main reasons.Clinical treatment works Middle discovery, intermittent urethral catheterization person intubate more than 5 times, indwelling catheter person by urinary catheter in internal more than 14 days almost 100% There is bacteriuria, easily drive in the wrong direction and cause urinary tract infection to urinary system breeding.

Along with the arrival of aging society, old man often because of acute urinary hesitancy or the chronic urinary hesitancy that the most freely causes because urinating and Bring life inconvenient and painful, once cause that urinary system infection even causes uremia, have a strong impact on health and threat to life.

The pathogeny having related disorders is analyzed by we, for the most traditional insertion catheter urethral catheterization The drawback of method, changes the urethral catheterization mode that invasive intubates, defines new urethral catheterization method.Carry for clinical treatment and home care A kind of brand-new Therapeutic Method and instrument are supplied.

The present invention has abandoned and has inserted the traditional method that catheter entrance bladder makes urine flow out in the past, but utilizes negative pressure to produce Suction makes periurethral tissue expand outwardly, lateral traction urethra and make lacuna of Morgagni expand, beneficially urine discharge, negative pressure produce Captivation collaborative bladder contraction made every effort to promote make urine discharge.It is described below about the mechanism of action of the present invention and goal of the invention:

1, lacuna of Morgagni narrows because of inflammatory congestion edema, and irriate produces spasm and urethra even can be made inaccessible and stop urine Liquid is discharged.The present invention utilize suction that negative pressure produces in external genital, make cavernous body of penis and periurethral tissue outwards in Centrifugum expansion, further lateral traction urethra and cause lacuna of Morgagni expand and resistance reduce, beneficially urine flow out.

2, prostate and bladder neck surrounding tissue are affected by the suction produced because of negative pressure, cause centrifugum expansion and Alleviate the pressure to urethra so that it is narrow lacuna expands, reduce the resistance of uroflow.

3, the resistance of lacuna of Morgagni and physiology narrow reduces because internal diameter expands, and prostate and bladder neck smooth muscle loosen Spasm is made to alleviate, so that the suction that negative pressure produces is more easy to urine slowly sucking-off.

4, urine sucking-off can make because urinary hesitancy causes that the bladder of excessively expansion progressively reduces volume, wall of urinary bladder tension force subtracts Little, smooth muscle loosening and recover contractility, the suction produced with negative pressure acts on down jointly, allows urine to discharge smoothly, alleviates The slight illness that urinary hesitancy brings.Use the tremolo that this device is subsidiary simultaneously, to wall of urinary bladder and corresponding diuresis acupoint massage, Promoting bladder contraction and alleviate sphincteral spastic contractions, auxiliary therapeutic action is played in the recovery to urinary function.

5, owing to the present invention need not plug in catheter, for noninvasive laser therapy measure, secondary infection can be avoided.The present invention The instrumentation developed is easy, and sufferers themselves or the most operable use of family members can use at home as caring articles for use. Increase the residual urine caused because of prostate hyperplasia, old man urinates not smooth or elderly woman urine water clock, it is possible to use the present invention Device periodically by intravesical accumulate residual urine sucking-off clear, make bladder periodically empty, it is ensured that bladder mucosa peace Sliding flesh has the blood flow of abundance, reduces recovery and the reconstruction of infection, beneficially bladder urination function.Keep that frequent uroflow is unobstructed makes urine Road system clean, makes infection progressively take a turn for the better, and treatment and the patient of the recovery of urinary function, beneficially underlying diseases get well.

Summary of the invention:

Cause urinary hesitancy in accordance with the above and urinate the most smooth relevant factor, and traditional treatment use intubate urethral catheterization institute The misery brought and inconvenience, even cause secondary urinary tract infection.We analyze cause urinary hesitancy and urinate the most smooth various because of Element and solution, avoid as far as possible or reduce use catheter, and development and design patent of the present invention " is exempted to intubate vacuum suction urethral catheterization Device ", the medical supplies of a kind for the treatment of and nursing are provided for clinical and family.

The mechanism of action of the product " Intubation-free negative pressure suction urethral catheterization device " that the present invention develops is the suction utilizing negative pressure to produce Make every effort to promote and make urethra peripheral tissues (penis of male and relevant connective tissue, the pudendum of women and relevant connective tissue) generation centrifugal Property expansion, the latter make urethra passively draw cause lacuna of Morgagni expand and beneficially urine flow out.Coordinate bladder position and relevant cave Position massage induces bladder contraction to recover urinary function.
