Bladder voiding dysfunction caused by damage to the central nerve or peripheral nerve that controls 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 more 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.

Detailed ways:

Example:

The principle block diagram of the present invention is as shown in accompanying drawing 1, comprises magnetic mover 1, stator 2 and the magnetic control device 3 that produces magnetic field in energized state, makes magnetic mover 1 be subjected to magnetic force, and wherein magnetic mover 1 includes by flexible A number of permanent magnet sheets 13 wrapped in the sheet 1, the flexible sheet 12 wrapped with the permanent magnet sheet 13 and the stator 2 are surrounded by a gourd shape and contained outside the bladder 10 to form a variable working cavity 11, and the flexible sheet 12 is wrapped with permanent magnet sheets. The upper end of the magnetic sheet 13 is in contact with the stator 2 and bonded, and the lower end of the flexible sheet 12 that is not wrapped with the permanent magnetic sheet 13 is respectively provided with the ureteral opening 9 that opens the ureter 8 to the ureteral opening a in the bladder wall and the urethra that is stuck in the urethra 6 The urethral bayonet 7 on the mouth b, and the lower end of the flexible sheet 12 that is not wrapped with the permanent magnet sheet is in contact with the stator 2 and bonded.

In this embodiment, the above-mentioned permanent magnet pieces 13 are permanent magnet pieces with the same polarity, and their arrays are fixed on the flexible piece 12 .

In order to ensure that the present invention has good compatibility with physiological tissues, the above-mentioned stator 2 is made of non-magnetic material. In this embodiment, the stator is made of non-metallic material into a mesh disk shape, and its lower end is fixed on the pubic bone of the human body. The above-mentioned flexible sheet 12 is a rubber sheet or a plastic sheet.

For the convenience of installation and use, in this embodiment, the above-mentioned magnetizer 3 is installed on the front abdominal wall 4 of the human body.

When the present invention is in use, when the bladder power pump is in the urine storage stage shown in Figure 1, the magnetic controller 3 is in a power-off state and does not generate a magnetic field, the magnetic mover 1 is in a relaxed state without being affected by magnetic force, and the bladder 10 is not compressed. The ureteral orifice a in the bladder wall remains open, while the rubber membrane wrapping the urethra 6 shrinks and compresses the urethra all the time, and the urethral orifice b remains closed. During this period, under the peristalsis of the ureteral sphincter, the urine enters the bladder 10 through the a port, and the bladder expands gradually with the increase of urine, and drives the magnetic mover 1 to float.

When the bladder power pump is in the urination stage shown in Figure 2, the magnet controller 3 is in the energized state, and the external magnetic field will adsorb the permanent magnet sheet 13 on the upper end of the magnet mover 1 to the stator 2, forcing the magnet mover 1 to tension and compressing the bladder 10 The ureteral orifice a in the bladder wall is closed, and the rubber membrane wrapping the urethra is pulled to loosen the urethral orifice b. Under the compression of the magnetic mover 1, the bladder 10 contracts to discharge urine. With the contraction of the bladder 10, the magnetic mover permanent magnet pieces 13 are adsorbed to the stator 2 column by column from top to bottom, the working volume 11 gradually decreases, and the magnetic mover 1 compresses the bladder 10 and gradually shrinks, thereby continuously transferring urine discharge.

When urinating, the patient can adjust the magnetic force through the magnetic controller 3 to control the urine flow rate. After urination, the magnetic control device 3 is powered off, and the bladder returns to the urine storage state, completing a process of storing urine and urinating. As long as the patient repeats the above process, he can control urination by himself.
