Description

Micro Electric Heating Device for Acupuncture and Moxibustion Needles

technical field

The invention relates to a miniature electric heating device for acupuncture needles.

Background technique

The operation method of warm needling moxibustion taught in textbooks and used in clinical practice is as follows: during the period of retaining the needle after getting Qi from acupuncture, pinch pure and soft moxa on the tail of the needle, or put a piece of moxa stick about 2cm long on the tail of the needle handle, Start to ignite moxibustion from the end near the skin. After the moxa or moxa sticks are burnt, remove the ashes and pull out the needles.

Although the heat of traditional warm needling moxibustion is transmitted along the needle body, it can quickly conduct to the deep tissue, and then spread around the needle body, which is an effect that is difficult to achieve in general thermal physical therapy. However, the traditional method of warming needling moxibustion still has the following inconveniences in clinical use:

1. The moxa ash and sparks in the burning or after burning are easy to fall off and scald the patient's skin or burn his clothes and be polluted by moxa smoke;

2. The distance between the moxa velvet or moxa stick and the skin cannot be adjusted. Keeping a fixed distance for fumigation may cause a burning sensation on the patient's local skin, or even scald the skin;

3. The moxa or moxa sticks will burn out quickly, and the burning time is uncontrollable. At the same time, a large part of the moxibustion heat is lost. It is troublesome to replace the moxa sticks when the number of continuous moxibustion is strong, so the heat cannot last and penetrate deeply;

4. The traditional warming acupuncture moxibustion of clinical moxa stick heating still uses the most primitive moxa stick, and the temperature of the needle piercing the human tissue part cannot be controlled, and the temperature range varies greatly during the treatment process. The highest temperature at the skin needle entry point is mostly concentrated in two areas of 36-40°C and 48-50°C, the highest can reach 54°C, while the lowest is only 35°C. Due to the difference in the length, thickness and length of the exposed needle body of the moxa stick, the heating temperature of the filiform needle varies among individual patients, and there may be a large difference in the temperature of the actual treatment of the transmitted tissue. Moreover, the needle retention time after acupuncture is uncontrollable.

Contents of the invention

The purpose of the present invention is to overcome the shortcomings of traditional warming needle moxibustion, make up for the deficiencies in the prior art, and provide a micro electric heating device for acupuncture needles with simple structure, low price and convenient use. The device is not only light and handy, but also has good heating effect , and the assembly with the filiform needle is reliable, and the disassembly is simple, which is beneficial for the doctor to perform warm acupuncture treatment on the patient.

The present invention is realized through the following technical solutions:

The miniature electric heating device for acupuncture and moxibustion needles of the present invention includes an electric heating conductor, which is characterized in that: an electric heating wire is provided inside the electric heating conductor, and a threaded connector for fixing the filiform needle is provided on the positioning surface of the electric heating conductor for installing the filiform needle.

The advantages of the present invention are as follows:

1. The miniature heating device of the present invention has small mass and small length, and is convenient to assemble with the filiform needle, and the load on the filiform needle handle is also small, so it is convenient for needle application;

2. The miniature heating device of the present invention can be used repeatedly, reducing waste of resources and reducing costs;

3. The threaded connector adopted by the micro-heating device of the present invention does not change the structure of the clinical filiform needle body, avoids contamination of the filiform needle body during assembly, and is not only convenient for clinical use. Moreover, it is beneficial to replace disposable needles without cross-infection;

4. It is convenient for doctors to assemble and disassemble the needle;

5. The filiform needle can be in close contact with the heat conductor, the heating efficiency is high, and the patient will not be scalded.
