Description

A Urinary Assisting System Driven by Ultrasonic Vaporization Steam

technical field

The invention belongs to the field of medical devices, and in particular relates to a urination assist system driven by ultrasonic vaporized steam, in particular to a urination assist system for patients with neurogenic bladder dysfunction.

Background technique

Bladder urination dysfunction caused by damage to the central nervous system or peripheral nerves that control urination in the human body is called neurogenic bladder dysfunction, also known as neurogenic bladder. Neurogenic bladder is a common disease. The etiology is mostly seen in spinal cord trauma, congenital dysplasia, and central nervous system lesions. It often has clinical symptoms such as urinary incontinence, dysuria, and urinary retention, which brings great pain to the patient. Pain and life impairment. Neurogenic bladder can also lead to complications such as urinary system infection and calculus. In severe cases, it can lead to hydronephrosis and even renal failure, which is life-threatening.

The treatment of neurogenic bladder is quite difficult. At present, clinical treatment methods such as drugs, electrical stimulation, surgery, and body nerve reflex are mainly used, or auxiliary voiding measures such as abdominal pressure, urethral catheter drainage, and cystostomy diversion are used. Drug therapy has many side effects and the curative effect is not obvious; electrical stimulation therapy requires surgical implantation of electrodes, and the curative effect is not yet clear; surgical therapy is limited by indications and is prone to complications; body nerve reflex therapy will damage the body motor nerves, and the curative effect remains to be seen; Urine cannot be drained by abdominal pressure, which can lead to stones and urinary tract infection; long-term intubation and drainage, bladder fistula diversion, pain for the patient, and easy to cause infection. At present, no more effective treatment method and assisted voiding measures have been found, especially the problem of bladder voiding dysfunction in paraplegic patients has not been effectively resolved.

Detailed ways

Example:

The structural diagram of the present invention is shown in Figure 1. The urination booster system driven by ultrasonic vaporization steam of the present invention includes an acoustic head 1, a base frame 2, a working medium 3, a driving bag 4, a cap membrane 5, and a urethral valve 8, wherein the acoustic The head 1 is an ultrasonic transducer, which can be held and pressed on the anterior abdominal wall 11 of the human body. The base frame 2 is a disc-shaped mesh structure made of alloy material. The base frame 2 is fixed on the pubic bone 10 of the human body, and the drive The bladder 4 is a pneumatic driver made of flexible elastic material. The upper end of the driving bladder 4 is fixed to the base frame 2. The working medium 3 is a liquid substance with a low boiling point, which is stored in the airtight driving bladder 4. The ureter 7 passes through the bladder wall section. The ureteral orifice a communicates with the bladder 6, and the urethral valve 8 is an elastic element that wraps the urethra 9 and controls the opening and closing of the urethral orifice b . The urethral valve 8 is fixed on the base frame 2, and the cover membrane 5 is made of a flexible non-elastic material. The periphery of the membrane 5 is fixed with the base frame 2 and the urethral valve 8 .

In this embodiment, the amount of elastic deformation of the elastic element of the urethral valve 8 is controlled by the tension of the cover film 5 .

In this embodiment, the above-mentioned driving capsule 4, cap membrane 5, and urethral valve 8 are all made of non-metallic materials.

The working principle of the present invention is as follows: in the urine storage stage, the acoustic head 1 does not receive high-frequency oscillation signals, does not generate ultrasonic waves, the liquid working medium is not vaporized by heat, the driving capsule 4 is not inflated, and the driving capsule 4 and the cover membrane 5 are both in the initial relaxation state, the bladder is not compressed, the ureteral orifice a of the bladder wall section of the ureter 7 remains open, and the elastic element of the urethral valve 8 keeps the urethral orifice b closed. During this period, under the peristalsis of the ureteral sphincter 7, urine enters the bladder 6 through the ureteral orifice a , and the bladder 6 expands gradually with the increase of urine, and drives the cap membrane 5 to float.

In the stage of urination, the acoustic head 1 receives high-frequency oscillation signals to generate ultrasonic waves. The liquid working medium 3 is heated and vaporized into steam, which drives the capsule 4 to expand and undergo elastic deformation, pushes the cover membrane 5 to tighten, and compresses the bladder 6 to make the ureter 7 the wall of the bladder. The ureteral orifice a is closed, and the elastic element of the urethral valve 8 is pulled to loosen the urethral orifice b . At the same time, the driving bladder 4 compresses the bladder 6 to continuously discharge urine.

After urination, the acoustic head 1 stops receiving the high-frequency oscillation signal, drives the steam in the bladder 4 to liquefy as the temperature drops, drives the bladder 4 to shrink, and the bladder 6 resumes the urine storage state, completing a process of urine storage and urination. As long as the patient repeats the above process, he can control urination by himself.
