An autonomous urination assist device and method

Abstract

The invention discloses an autonomous urination assisting device and method. The device uses a combination of 16-channel electrode sheets and multiple wire electrodes to target and stimulate T12-L2 of the spinal cord and S2-S3 of the spinal cord sacral nerves, and transmit electrical stimulation signals to Acting on the corresponding areas of the spinal cord and related sacral nerves, it can adjust the detrusor-sphincter synergy, so that when the urine in the bladder reaches a certain amount, the bladder pressure will be increased to promote urination. It has an auxiliary therapeutic function for urinary frequency and urinary incontinence. To a certain extent, the upward conduction function of the stimulation signal is improved; at the same time, the device measures the urine volume in the bladder in real time through the implanted flowmeter, and reminds the patient to urinate at the right time according to the analysis of the urine volume and preset different thresholds, eliminating the need to directly set the external The monitoring method of parameters is more humanized and intelligent.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, and more specifically relates to an autonomous urination auxiliary device and method. Background technique [0002] At present, urinary retention is a common complication after spinal cord injury. Clinically, it is often necessary to indwell a urinary catheter to solve the problem that patients cannot urinate spontaneously. Mentally, depression is easy to occur. On the other hand, long-term catheterization and drainage will cause the bladder capacity to be too small, and long-term catheterization in the body is also prone to infection, which directly endangers health. [0003] In order to overcome the various inconveniences caused by the indwelling urinary catheter, an electric stimulator of the anterior root of the sacral nerve with an embedded method was developed. Shortcomings such as poor coordination lead to insufficient urine storage in the bladder, which causes increas...

Problems solved by technology

[0005] In view of this, the present invention provides an autonomous urination assisting device and method, which measures the amount of urine in the bladder in real time by adding an implanted flowmeter and transmits the data to an external control device. When the volume reaches a certain threshold, the external controller will control the action electrode to stimulate the nerves in contact with it to urinate, so that when the urine in the bladder reaches a certain amount, the bladder internal pressure will be increased to promote urination, which solves the problem that the sacral nerve stimulator cannot be controlled by the patient's bladder. The real-time urine storage status sends stimulation signals, which leads to unsatisfactory results
