Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a muscle group electrical stimulation device based on respiratory muscle force feedback. Background Art

[0002] The cardiopulmonary muscle function therapeutic device is a respiratory therapy device that can effectively improve lung ventilation function and promote lung rehabilitation. Through 6 pairs of external electrodes, the inspiratory phase (phrenic nerve-diaphragm) and expiratory phase (abdominal muscle) are stimulated by coordinated feedback electrical stimulation, so that the inspiratory phase (phrenic nerve-diaphragm) and expiratory phase (abdominal muscle) contract regularly, effectively enhancing the diaphragm activity and abdominal muscle thickness, increasing tidal volume, improving exhalation capacity, and enhancing respiratory muscle strength and endurance. It is used for respiratory muscle rehabilitation treatment and can also assist patients with weak cough to expectorate.

[0003] When the electrodes of the cardiopulmonary muscle function therapy device touch the skin, it is usually necessary to apply conductive gel. This gel helps to improve the conductivity between the electrode and the skin, ensuring smooth signal transmission while reducing skin irritation. Make sure to clean the skin before use to improve the effect and comfort.

[0004] When using the existing cardiopulmonary muscle function therapeutic device, it is necessary to manually apply the conductive gel to the patient's skin or electrode sheet. It is not convenient to automatically apply the conductive gel to the electrode sheet, and manual application is difficult to ensure that the ideal uniformity can be achieved every time. This may affect the contact impedance between the electrode and the skin, and then affect the stability and accuracy of signal transmission, affecting the treatment effect.

By setting an easily detachable U-shaped smearing rack and automatic application tube, it is convenient to clean the agglomerated conductive gel, which can maintain long-term use effect and hygiene standards.
