Abstract

The invention discloses a sacral nerve electrical stimulation system, relates to the field of medical apparatus and instruments, and solves the problem that an existing sacral nerve electrical stimulator is liable to harm patients. A control unit comprises a boosting amplitude modulation unit, a pulse signal amplification unit, a master control unit, a human-computer interaction unit and a communication unit, wherein the master control unit is independently connected with the boosting amplitude modulation unit, the pulse signal amplification unit, the human-computer interaction unit and the communication unit; an emitter is connected with a receiver through the communication unit; the mater control unit controls the boosting amplitude modulation unit to output an adjustable voltage pulse signal; the pulse amplitude value of the adjustable voltage pulse signal is amplified to a required numerical value through the pulse signal amplification unit, and then, the required numerical value is transmitted to the emitter; the pulse signal emitted through the emitter is received through the receiver in a body to realize pulse signal stimulus for a corresponding neure; and the human-computerinteraction unit is used for displaying each parameter value of the pulse signal. The system is favorable for improving the bladder urination function of a spinal cord injury patient, and preventingand controlling urinary system infection.

Description

Technical field [0001] The present invention relates to the field of medical equipment, in particular to a sacral nerve electrical stimulation system. Background technique [0002] Traditionally, most patients with spinal cord injury are treated with drugs, intermittent urinary catheterization or surgical treatment. However, in the long-term treatment process, there are disadvantages such as unsatisfactory results and many complications. At present, sacral nerve root stimulators are used for treatment. When intermittent pulse stimulation is used in this method, urination can occur due to the continuous increase in bladder pressure during the two stimulations, but this urination method is still artificial urination, and the stimulation parameters cannot be adjusted properly, which may easily cause kidney damage. In addition, When using the anterior sacral nerve root stimulation system, a posterior sacral nerve root resection is required, which is unacceptable for some patients. [...
