Stretchable high-density pelvic floor rehabilitation electrode

Abstract

The invention discloses a stretchable high-density pelvic floor rehabilitation electrode which an elastic cavity, electrode arrays, a handle and a pipeline. The elastic cavity is provided with a cylindrical or oval cavity body with expansion and shrinkage capacities, an input port is formed in one long axis end, the electrode arrays serve as a part of the surface of the elastic cavity and are exposed on the outer surface of the cavity body, electrode connecting wires are arranged on the thin wall buried layer of the elastic cavity, insulated from the outer surface and led out from an input endof the cavity body after being aggregated, the handle is fixed onto the input port, a spacer is arranged between the handle and the input port, the pipeline penetrates the handle and the spacer and is led into the elastic cavity, both the elastic cavity and the electrode arrays have extensibility, the elastic cavity can be changed into the cylindrical or oval cavity body with the expansion and shrinkage capacities after gas or liquid is led into the cavity through the pipeline, and the electrode arrays of the surface of the cavity body are closely fitted with inner pelvic floor cavity tract wall with a complex shape. The electrode can be electrically stimulated and can acquire multi-channel data and transmit electrophysiology 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
