Abstract

The invention provides an impedance test method and system and an electronic device with the system. The impedance test method comprises the follow steps of selecting a test pulse in a plurality of output stimulus pulses via a predetermined selection rule to acquire at least one positive phase voltage and at least one negative phase voltage; and calculating an impedance value in an electrode loop via the acquired positive phase voltage the acquired negative phase voltage. The impedance test method and system and the electronic device with the system are advantageous in that, the impedance between electrodes of a sacral nerve implantation stimulator is accurately tested, and a guiding effect is provided for function regulation of a patient.

Description

technical field [0001] The invention belongs to the technical field of sacral nerves, and relates to a testing method and system, in particular to an impedance testing method, system and electronic equipment with the system. 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 sph...
