Description

Wearable carbon fiber infrared moxibustion device

technical field

The utility model relates to the technical field of medical equipment, in particular to a wearable carbon fiber infrared moxibustion device.

Background technique

In modern society, with the acceleration of the work rhythm, people generally spend more time working in the office, long-term exposure to air-conditioned environment, and prolonged sitting, lack of exercise caused by sub-health conditions are very common, such as neck, shoulder, waist and leg pain, etc. The incidence of chronic diseases has increased significantly, and many researchers are committed to researching medical and health care products that can improve people's sub-health status or prevent and treat chronic common diseases. In traditional Chinese medicine, traditional moxibustion therapy uses burning moxa velvet, moxa sticks or moxa sticks to burn or iron the affected area or meridian acupoints, using its warm stimulation and the effect of drugs to improve blood circulation, dredge the meridians, and achieve warming and dispersing. The effects of cold pathogens, activating blood circulation, rejuvenation of Yang, and disease prevention and health care are simple and effective methods for many diseases.

Traditional moxibustion is to hold moxa sticks, or put moxa sticks and spacers on the acupoints, or put the moxa sticks in a moxibustion box, and then moxibustion on the affected part or body surface acupoints after ignition. Although the method is simple and the curative effect is outstanding, traditional moxibustion is not safe to burn. During treatment, the temperature can only be obtained by helping the patient's perception, which cannot be precisely controlled, and the fire of moxa falls, often causing skin burns; moxibustion burning releases a lot of moxa smoke, It cannot be used in public places such as offices; moxibustion cannot achieve simultaneous multi-site and multi-acupuncture treatment, especially the back of the neck needs to be operated by a special person; The practical application of moxibustion therapy has been greatly limited.

In order to solve many problems in the clinical operation of traditional moxibustion therapy, many targeted improvements have been proposed. For example, the patent publication number CN206183643U proposes an electric heating moxibustion instrument, which simplifies the moxibustion operation and saves manpower. However, the heating component of the traditional moxibustion instrument and the instrument shell are directly connected. The heat will be conducted to the surface of the casing through the heating components, resulting in an excessively high temperature of the casing, affecting the safety of users. In order to improve the defect of moxa smoke released by the burning of moxa sticks, a non-combustion moxibustion therapeutic apparatus is proposed. For example, the invention patent with the publication number of CN204484760U proposes a portable multi-functional photoelectric moxibustion apparatus, but it requires an external power supply as a laser generator. Power supply, cannot be used anytime, anywhere. The invention patent publication number CN205515519U proposes an electronic moxibustion instrument based on PID temperature control, which can precisely control the temperature of moxibustion, but its heat source is a heating resistor, which generates infrared rays by heating the ceramic sheet through resistance heating, and heats the ceramic sheet through resistance heating. The method is difficult to achieve uniform heating. At present, most infrared moxibustion instruments do not consider the problem of burns caused by excessive moxibustion temperature if the temperature measurement and control system fails.

However, none of the above improvements have well met the needs of modern moxibustion technology development and practical application, such as safety, portability, convenient operation, multi-part, anytime, anywhere, independent completion, and no impact on work. This is where this application needs to focus on improving.
