Stimulation state adjustment method in sacral nerve stimulator

Abstract

The invention provides a stimulation state adjustment method for a sacral nerve stimulator. The sacral nerve stimulator achieves the state adjustment in an automatic mode, and the method specifically comprises the following steps: 1), obtaining an initial stimulation parameter and an expected stimulation effect value; 2), starting the sacral nerve stimulator to carry out stimulation; 3), obtaining a nerve reaction voltage value V of measuring electrodes and an impedance value r between the measuring electrodes in a stimulation process after the stimulation of each N pulses, calculating a current nerve reaction effect value nr according to the nerve reaction voltage value V and the impedance value r, and comparing the calculated current nerve reaction effect value nr with the expected stimulation effect value: enhancing the stimulation if the calculated current nerve reaction effect value nr is less than the expected stimulation effect value, or weakening the stimulation of the calculated current nerve reaction effect value nr is greater than the expected stimulation effect value. The method achieves the automatic adjustment of the sacral nerve stimulator, so as to achieve a better use effect.

Description

technical field [0001] The invention relates to a sacral nerve stimulator, in particular to a stimulation state adjustment method in the sacral nerve stimulator. Background technique [0002] Bladder diseases such as urinary incontinence and frequent urination are usually caused by damage to the nervous system and spinal cord. Medical research and practice have confirmed that applying electrical stimulation to the relevant nerves is an effective treatment method. Many studies have shown that stimulating the anterior root of sacral nerve S2\S3\S4 can affect the action of bladder detrusor and external urethral sphincter, so that the use of appropriate stimulation signals can inhibit the hyperreflexia of bladder detrusor and achieve the purpose of relieving urinary incontinence; A specific stimulation pulse sequence can be used to stimulate the coordinated action of the bladder detrusor and the external urethral sphincter to achieve controlled voiding. [0003] The existing sa...
