A bladder automatic urinating system guided by ultrasonic three-dimensional images

Abstract

Provided is a bladder automatic urinating system guided by ultrasonic three-dimensional images. The bladder automatic urinating system comprises a three-dimensional ultrasonic probe used for acquiring bladder three-dimensional data in real time, a power supply module used for supplying power to the system, a first field programmable gate array (FPGA) connected with the three-dimensional ultrasonic probe, a second FPGA connected with the first FPGA and a temperature sensing device arranged on an electrode array module and used for monitoring electrode temperature in real time, pulse amplifying units connected with the output of the second FPGA, an electrode array module connected with the output ends of the pulse amplifying unit, and a treatment information saving module connected with the second FPGA. The bladder automatic urinating system accurately positions the position of a bladder with the ultrasonic three-dimensional images, determines the position of a detrusor and the position of an external urethral sphincter according to physiological structure, and stimulates the detrusor and the external urethral sphincter with pulses in different frequencies and amplitudes so as to stimulate the bladder to complete a urinating process accurately and noninvasively under the ultrasonic three-dimensional guidance.

Description

Technical field [0001] The invention relates to a system for promoting autonomous urination. In particular, it relates to an ultrasonic three-dimensional image guided bladder autonomous urination system for treating urination dysfunction caused by spinal cord injury. Background technique [0002] The spinal cord is the primary urination center that controls the functional activities of the detrusor, urethral muscles, and external sphincter. It is also a common pathway between the sensory impulse of the bladder and urethra and the advanced urination center. Spinal cord injury refers to the damage to the structure and function of the spinal cord caused by external direct or indirect factors, resulting in the impairment of spinal cord nerve function below the injury level. According to the statistics of the Spinal Cord Injury Committee in 2011, there are about 1 million people with spinal cord injury in my country, and it is increasing at a rate of 10,000 per year.

Problems solved by technology

Urinary catheterization can easily cause urinary tract infection and bring inconvenience to patients' lives. Surgical treatment and implantable electrical stimulation treatment bring great pain to patients and are expensive. Magnetic stimulation treatment is difficult to stimulate deep nerves.

The ideal method for treating bladder dysfunction is electrical stimulation, but the existing electrical stimulation treatment equipment has the following disadvantages: 1) The location of electrical stimulation is unscientific, such as the Chinese patent portable non-invasive bladder therapy instrument (200910104124. Acupuncture points around the bladder, but its design cannot obtain bladder position information from the outside, nor can it adjust the electrical stimulation position according to the bladder of different people, and the stimulation position is not scientific

2) The shape and size of the bladder will change during urination, which will lead to the failure of electrical stimulation. At this stage, the equipment cannot adjust the position of the stimulation point according to the change, and at the same time increase the invalid stimulation

3) It is impossible to distinguish between stimulation failure and urine discharge, no real-time monitoring of bladder volume, no feedback mechanism for residual urine volume, and no way to determine whether there is residual urine. You can only stop stimulation when it fails or randomly transpose stimulation, which will cause Electrical overstimulation or urinary retention
