A scalable high-density pelvic floor rehabilitation electrode

Abstract

The invention discloses an extensible high-density pelvic floor rehabilitation electrode, which includes an elastic cavity, a cylindrical or elliptical cavity with expansion and contraction capabilities, and an input port on one end in the long axis direction; an electrode sheet array, which As part of the surface of the elastic cavity, the electrode array is exposed on the outer surface of the cavity, and the electrode wires are wired in the thin-walled buried layer of the elastic cavity and insulated from the outer surface. After the electrode wires are gathered, they are drawn out from the input end of the cavity; the handle, its The input port is fixed, and a gasket is provided between the handle and the input port; the pipeline passes through the handle and the gasket, and leads into the elastic cavity; the elastic cavity and the electrode array are both malleable, through After the pipeline is filled with gas or liquid, the elastic cavity will form a cylindrical or elliptical cavity with the ability to expand and contract. The electrode array on the surface of the cavity closely fits the inner wall of the pelvic floor cavity with complex shapes. The electrodes can be electrically stimulated, collected Multi-channel data and transmit electrophysiological signals.

Description

technical field [0001] The invention belongs to the field of biomedicine, and in particular relates to an extensible high-density pelvic floor rehabilitation electrode. Background technique [0002] The pelvic floor, also known as the pelvic diaphragm, is made up of layers of muscle and fascia that seal off the pelvic outlet, through which the urethra, vagina, and rectum emerge. Pelvic floor dysfunction is a common disease and high incidence for women, and it has become one of the chronic diseases that threaten women's health and quality of life. It is a series of diseases caused by the displacement or dysfunction of the patient's pelvic organs due to weak bottom support or decreased muscle function. In order to check the state of the pelvic floor muscles, assist in the diagnosis or differential diagnosis of pelvic floor dysfunction diseases, understand the progress of the patient's pelvic floor function recovery and evaluate the treatment effect, the most commonly used and...

AI Technical Summary

Problems solved by technology

[0004] Traditional surface pelvic floor electrodes are roughly divided into two types. One is a single-channel large-area electrode, which is easier to collect EMG signals. However, due to the large electrode area, it is impossible to accurately locate the pelvic floor muscle position, which is likely to bring many irrelevant findings. Muscle crosstalk affects the accuracy of the signal and subsequent diagnosis; the other is a multi-channel electrode. Compared with the first electrode, this electrode can accurately locate the muscle position, but because its material is hard, it cannot be guaranteed. The close fit with the human body makes it impossible to accurately collect myoelectric signals, and when the electrodes and the human body move with each other, motion artifact interference signals that are several times larger than the myoelectric signals will be generated, affecting the accuracy of the signals and subsequent diagnosis
