Description

A multi-channel thermal moxibustion instrument

technical field

The invention relates to a thermal moxibustion device using electric energy, which belongs to the field of medical and health care equipment.

Background technique

Hot compress is a commonly used method of treatment and physical therapy in traditional Chinese medicine. Hot compress therapy is to use hot objects such as hot water bags or hot towels to place on the painful area to eliminate or relieve pain. This is an ancient hot compress therapy. It can dilate local capillaries, accelerate blood circulation, and play the role of anti-inflammatory, detumescence, dispelling cold and damp, relieving pain and eliminating fatigue. Because this method is simple and easy to implement and has rapid results, it has not only been used since ancient times, but also has become one of the commonly used treatments for self-prevention and treatment in people's daily life.

Electrothermal moxibustion is a moxibustion method that uses electricity as the heat source. Electric moxibustion instruments are non-moxibustion heat source moxibustion instruments jointly developed by modern acupuncture workers and workers in other disciplines, and have been continuously improved and perfected, so there are many types of such moxibustion instruments. Among them, the application of simulated moxibustion therapeutic apparatus is more common. The so-called simulated moxibustion instrument is based on the spectrum radiated by traditional moxibustion when it burns, using simulation technology to simulate, fully exerting the functions of traditional moxibustion to warm meridians and dispel cold, dredge meridians, promote blood circulation, remove blood stasis, reduce inflammation and relieve pain, and has no Pollution without damage, easy to operate.

At present, this type of instrument is being further improved. For example, matching probes with different diameters are used to apply to different parts of the human body, which is more conducive to the treatment of diseases. In addition, another electrothermal moxibustion method has emerged in recent years: wind moxibustion. Wind moxibustion combines traditional Chinese medicine with the electric heat effect of modern technology. Using the heat generated by electricity, the traditional Chinese medicine formula contained in the wind moxibustion instrument is directly blown to the human skin, meridians, acupoints, orifices or diseased parts in the form of hot medicinal wind. Through skin penetration, meridian conduction, orifice mucous membrane absorption, it integrates heat, medicine, and physical therapy to achieve the purpose of promoting qi and blood circulation, dredging meridians, reducing inflammation and relieving pain, strengthening the body and eliminating pathogens. However, the structure of this instrument is complicated and the cost is too high.

Although electrothermal moxibustion has various benefits, it is still not widely used. The main reasons are as follows:

1. Because the existing electrothermal moxibustion instrument is mainly for thermal stimulation of acupoint skin, if infrared heating is used, infrared lamps are needed, and infrared lamps are difficult to apply to small probes, or the effect is not satisfactory, so The existing heat moxibustion instrument can not achieve the ideal effect of traditional moxibustion;
