Description

Technical Field

[0001] The present invention relates to the technical field of electrical stimulation devices, in particular to an electrical stimulation system for enhancing respiratory muscle function. Background Art

[0002] Respiratory muscle function is essential for human respiratory health. Certain chronic respiratory diseases may cause patients to have symptoms such as dyspnea and muscle weakness. In severe cases, external instruments may be needed for auxiliary treatment. Respiratory neuromuscular electrical stimulation is a passive method that uses low-frequency current to stimulate nerves and muscles to treat muscle dysfunction. It promotes muscle contraction and nerve conduction by applying current stimulation to specific muscles or nerve areas, thereby enhancing muscle strength and endurance. This treatment method has been widely used in rehabilitation therapy to help restore muscle function, improve muscle coordination and control, and improve muscle movement efficiency.

[0003] In the prior art, electrical stimulation of the abdominal muscles of users through physical therapy devices has achieved certain results. However, these physical therapy devices can usually only provide electrical stimulation according to preset parameters. The electrical stimulation of the physical therapy device cannot be kept consistent with the user's breathing state in real time, resulting in limited treatment effects. There are differences in breathing frequency and depth for different users, but existing physical therapy devices can usually only provide fixed electrical stimulation parameters and cannot meet personalized treatment needs. Summary of the invention

[0004] The purpose of the present invention is to provide an electrical stimulation system for enhancing respiratory muscle function. By providing an elastic belt and an airflow sensor, the electrical stimulation is synchronized with the user's breathing, thereby solving the problem that it is difficult to keep the electrical stimulation of a physiotherapy device consistent with the user's breathing state.

[0005] The present invention is achieved through the following technical solutions: The present invention is an electrical stimulation system for enhancing respiratory muscle function, comprising a physiotherapeutic instrument body and an elastic band. A control module is electrically arranged at the bottom of the physiotherapeutic instrument body. A rubber tube is connected to the physiotherapeutic instrument body. The end of the rubber tube is connected to the middle of the elastic band. Connecting bands are installed at both ends of the elastic band. Male buckles and female buckles are respectively installed on the corresponding outer surfaces of the two connecting bands. The male buckles and female buckles are pasted to each other. A through hole is provided on the elastic band. A silicone tube is provided in the through hole. An airflow sensor is provided inside the silicone tube.

The rubber tube is located in the L-shaped groove. An incorporation groove and a storage groove are provided at the bottom of the storage block. The number of the storage grooves is two. The incorporation groove is connected to the two storage grooves. The elastic band passes through the incorporation groove and is located in the storage groove.

[0006] Furthermore, a connecting wire is arranged inside the rubber tube, and an end of the connecting wire is electrically connected to the control module.

[0007] Furthermore, a winding hole is opened inside the elastic band, and the end of the rubber tube passes through the winding hole and is electrically connected to the airflow sensor.

[0008] Furthermore, the L-shaped groove has a penetration groove and a limiting groove, the penetration groove and the limiting groove are connected, and the rubber tube passes through the penetration groove and is wound in the limiting groove.

[0009] Furthermore, the storage block is provided with four adjustment holes, and bolts are fitted in the four adjustment holes.

[0010] Furthermore, a stimulation electrode part is arranged on the physiotherapy instrument body, and the stimulation electrode part has a connector, an electrode wire and an electrode patch, and two ends of the electrode wire are respectively connected to the electrode patch and the connector.

[0011] Furthermore, an interface is provided on the body of the physiotherapy instrument, and the connector is plugged into the interface.

[0012] Furthermore, an L-shaped block is installed on the outer surface of the physiotherapy instrument body, a slide groove is opened in the L-shaped block, a slider is slidably fitted in the slide groove, a stopper is installed on the top of the slider, and the stopper contacts the outer surface of the joint.
