technical field

The utility model relates to the technical field of medical equipment, in particular to a disposable pelvic floor biofeedback electrode patch.

Background technique

With the continuous progress and development of medical science and technology, the understanding and understanding of bioelectricity is gradually deepening. Bioelectricity is the most basic physiological phenomenon of living organisms. In the process of collecting and utilizing various biopotential signals, biomedical electrodes are used as A sensor that can effectively convert the ionic potential generated by the electrochemical activities of organisms into the electronic potential of the measurement system is widely used in the electromyography (EMG) measurement of basin biofeedback.

In the diagnosis and treatment of pelvic floor biofeedback, the electrode patch is one of the core components of pelvic biofeedback EMG measurement, which can play the role of excitation, collection and conduction of bioelectrical signals. Existing electrode patches are usually silver/silver chloride electrodes. Silver/silver chloride electrodes are usually formed by electroplating/electrolysis and other processing techniques. Under the condition of small current passing through the electrodes, they can be regarded as non-electric polarization electrodes. In the detection of pelvic floor electromyographic signals, silver/silver chloride electrodes can not only convert ionic current into electronic current under low current conditions, but also have the advantages of stable electrical signal baseline, convenient manufacture and use, and low price.

However, the silver/silver chloride electrode used in the prior art has the following defects or deficiencies: 1. Due to the existence of conductive gel in the existing silver/silver chloride electrode, the silver/silver chloride electrode is prone to occur during use. Dehydration and drying will cause some changes in the electrical properties of the conductive gel, which will easily introduce large noise and errors in high-precision experiments, resulting in inaccurate measurement results; 2. Before using silver/silver chloride electrodes, The skin must be effectively treated, and the cuticle on the surface should be wiped off as much as possible. It takes time to prepare. What's more serious, the conductive gel may cause skin allergic reactions, redness, swelling, etc.; 3. Need for electrode pads It sticks to the surface of the skin for several hours, and it is easy to sweat. However, the existing electrode pads usually have a gasket between the non-woven fabric and the electrode core. The purpose of the gasket is to make the gap between the electrode core and the non-woven fabric The connection is tight and reliable. In the state of use, the gasket covers most of the area of the non-woven fabric, resulting in poor air permeability of the entire electrode sheet.

In summary, there is an urgent need for a disposable pelvic floor biofeedback electrode patch that is accurate in measurement, prevents allergies, has good air permeability, and is not easy to sweat. And there is no report about this pelvic floor biofeedback electrode patch at present.
