An artificial detrusor system driven by shape memory fibers

Abstract

The invention provides an artificial detrusor system driven by a shape memory fiber. The artificial detrusor system comprises an in-vitro high-frequency power source, a transmitter, an implanted in-vivo receiver, a driver, a bracket, a urethra valve and a flow distribution band, wherein the transmitter comprises a magnet exciting coil and a transmitting coil, and is handheld to be adhered to a front wall of the abdomen when in operation; the receiver comprises a receiving coil and a loading coil and is fixed to pubis; the driver is fixed to the bracket which is fixed to the pubis; the urethra valve comprises a valve body and a valve core; the valve core is arranged in the valve body; the valve body is fixed to the bracket; the flow distribution band is connected with the driver and the valve core of the urethra valve. The artificial detrusor system does not cause muscular tissue infection of the wound, the infection and complications of a urinary system, mechanical injury of organs and leakage and backflow of urine, is compact in structure, and has favorable compatibility with biological tissues.

Description

technical field [0001] The invention belongs to the field of medical devices, and relates to an artificial detrusor system driven by shape memory fibers, in particular to an artificial detrusor system for assisting urination in patients with neurogenic bladder dysfunction, which belongs to the innovative technology of the artificial detrusor system . Background technique [0002] 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 infectio...

AI Technical Summary

Problems solved by technology

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, patient pain, and easy to cause infection

At present, no more effective treatment methods and assisted voiding measures have been found, especially the bladder voiding dysfunction of paraplegic patients has not been effectively resolved
