Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of medical equipment, especially relates to a heat dissipation assembly of fire needle device. BACKGROUND

[0002] Fire needle, also known as "burning needle", "burning acupuncture" and "burning needle", is a kind of acupuncture method that the needle is heated and inserted into certain parts or acupoints of the human body and then quickly withdrawn to treat diseases. Fire needle therapy has a history of thousands of years in China. With the clinical application and research of physicians in different dynasties, fire needle therapy has been continuously developed and improved, and has become a unique medical system in acupuncture therapy. Fire needle has excellent effects in treating various cold symptoms, pain, meridian diseases, skin diseases and gynecological diseases. In the actual operation process of fire needle in clinical practice, "red, accurate and fast" are emphasized, and the high-temperature fire needle can be accurately and quickly inserted into acupoints and withdrawn. According to the operation requirements in the national standard of fire needle, the needle body should reach "red burning", so the burning temperature of the needle body of the fire needle device should be at least 600 DEG C or above.

[0003] At present, alcohol lamps or cotton balls are commonly used to heat fire needles in clinical practice. These burning needle methods are all open flame combustion, and the safety is relatively poor. If there is any carelessness, fire or burns may occur. At the same time, the patient directly sees the red-hot needle, which causes fear and nervousness, and even muscle spasm, which greatly disturbs the treatment of fire needle.

[0004] There are also fire needle products using heating pipes on the market. In order to facilitate heat dissipation, some directly expose the red-hot heating pipe to the air. The surface of the red-hot heating pipe has a high temperature of at least 650 DEG C. If the hand accidentally touches it, it is easy to cause medical accidents. Some increase a plastic or metal protective shell outside the heating pipe, and adopt a passive natural heat dissipation method. However, according to the use scene of the fire needle product, it is often moved for treatment in different parts of the human body, which determines that it belongs to a small portable product and cannot be made too large. If the accumulated heat in the cavity outside the heating pipe cannot be dissipated in time, it will cause the aging of the plastic shell for a long time, shorten the service life of the product, and also form a high-temperature impact on the internal components of the product, causing the product to fail. The use of metal shell will cause the shell temperature to be higher than 150 DEG C. Such high temperature poses a safety hazard to doctors and patients, and also fails to meet the high-temperature safety requirements of medical devices. UTILITY MODEL CONTENTS
