This is an electrotherapy device, which is often used for physical rehabilitation or pain relief. When low frequency is used in the treatment, weak current begins to act on human body in a low frequency way, and the sensory receptors of muscles and nerve endings in muscles are directly stimulated by electrode sheets, so that muscles contract unconsciously, thus relaxing sore muscles and nerves caused by fatigue or injury, promoting local blood circulation and alleviating or relieving pain.
At present, low-frequency therapeutic apparatus is widely used in rehabilitation treatment in hospitals, orthopedics hospitals and acupuncture hospitals, and it is one of the widely used electrotherapy. The electric shock massager consists of two to several rubber pads attached to the skin, which stimulate muscles and nerves through micro-current.
Extended data:
Low-frequency electrotherapy instrument, the full name of microcomputer low-frequency electrotherapy instrument, is used to treat neurasthenia, irritable bowel syndrome, scapulohumeral periarthritis and so on.
Low-frequency pulse current has three main physiological and therapeutic effects:
1, excites neuromuscular tissue
2. Promote local blood circulation
3. Three important functions of analgesia.
In recent years, many low-frequency therapeutic instruments have appeared on the market. The circuit can output various massage techniques simulating human hands, with adjustable strength and various modes to choose from. All kinds of components are common components in the market, and inductors are common color ring inductors. It is best to use the patch dedicated to the therapeutic instrument for the output.
