Description

Technical Field

[0001] The present invention relates to the technical field of rehabilitation therapy, and in particular to a low-frequency therapeutic apparatus. Background Art

[0002] Low-frequency therapy device is a rehabilitation and physiotherapy device, which mainly uses low-frequency current to stimulate the nerves, muscles and other tissues of the human body to achieve the purpose of treating diseases or relieving symptoms. Low-frequency therapy devices widely use adsorption bowls for adsorption and electrical stimulation treatment. Its working principle is to fix the electrodes on the treatment part of the human body after vacuuming the adsorption bowl to a negative pressure state, and to contact the electrodes in the adsorption bowl with the wet absorbent sponge, and contact the human body through the absorbent sponge. The paired adsorption bowls form an electrical circuit to perform electrical stimulation rehabilitation treatment and negative pressure cupping treatment on the human body.

[0003] The Chinese patent application number 202222729909.3 discloses an adsorption bowl and rehabilitation equipment, including: an adsorption bowl body, an air circuit output interface and a control module; wherein the air circuit output interface is used to connect a negative pressure exhaust pipeline; the control module is installed at the bottom of the outer bowl of the adsorption bowl body and is connected to the device host for communication, and the control module includes an input module for receiving control commands for the adsorption bowl body and a display module for displaying the working status of the adsorption bowl body. The control commands for controlling the adsorption bowl body and the control module for displaying the working status of the adsorption bowl body are fixed at the bottom of the outer bowl of the adsorption bowl. However, although the invention allows users to adjust and check the working status of the adsorption bowl by themselves without having to get up and go to the device host to adjust and check, which effectively reduces the risk of the adsorption bowl falling off and improves safety. Users can use the adsorption bowl by themselves without the help of others, which enhances the user experience. However, there is still a problem that it can only adsorb on flat parts such as the back, and it is not firmly adsorbed or cannot adsorb on uneven parts such as shoulders, elbows, and knees. There is also the problem that after long-term treatment, part of the moisture in the absorbent sponge is absorbed or dried, resulting in reduced conductivity or poor skin contact, and it is difficult for the current to be effectively conducted from the electrode to the human skin, or when the electrode cannot contact the skin evenly, the current may be concentrated in some small areas with good contact, which can easily cause local skin tingling or burning sensation. There is also a problem that when water enters the negative pressure pipeline, the humid environment in the pipeline will breed bacteria or mold and cause treatment infection.
