Independent urination assistant device and method

Abstract

The invention discloses an independent urination assistant device and method. By adopting a mode of combining 16-channel electrodes and a plurality of lead electrodes, the device is used for performing target stimulation on T12-L2 of the spinal cord and S2-S3 of spinal sacral nerves, working an electric stimulation signal on corresponding areas of the spinal cord and related sacral nerves to adjust synergistic effect of detrusor-sphincter, so that the intravesical pressure is increased to promote urination when the urine in the urinary bladder reaches a certain amount, and an assisted treatment function on frequent micturition and urinary incontinence can be achieved, and the uplink conduction function of the stimulation signal can be improved to a certain extent; and the device can be used for metering the urine amount in the urinary bladder through an implanted flowmeter and reminding patients to urinate at a proper time according to analysis on the urination amount and preset different thresholds, and discards a monitor mode of directly setting external parameters, thus being humanized and smart.

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
