Description

Technical Field

[0001] The invention relates to a simulation training device for acupuncture needle techniques. Background Art

[0002] Acupuncture is the general term for acupuncture and moxibustion. Acupuncture refers to inserting needles (usually filiform needles) into the patient's body at a certain angle under the guidance of traditional Chinese medicine theory, and using acupuncture techniques such as twisting and lifting to stimulate specific parts of the human body to achieve the purpose of treating diseases. The insertion point is called acupoints of the human body, or acupoints for short. According to the latest acupuncture textbook statistics, there are 361 regular acupoints on the human body. Moxibustion is to burn and fumigate certain acupoints on the body surface with pre-made moxibustion sticks or moxibustion grass, and use heat stimulation to prevent and treat diseases. Usually, moxa is the most commonly used, so it is called moxibustion. There are also methods such as herbal moxibustion, willow moxibustion, wick moxibustion, and mulberry branch moxibustion. Nowadays, moxa stick moxibustion is often used in people's lives. Acupuncture consists of needles and moxibustion, and is one of the important components of oriental medicine. Its content includes acupuncture theory, acupoints, acupuncture techniques and related instruments. In the process of formation, application and development, it has distinct Chinese cultural and regional characteristics, and is a valuable heritage based on Chinese cultural and scientific traditions.

[0003] Due to the complex distribution of meridian points in the human body and the ever-changing situation, acupuncture occupies a very important part in the development of traditional Chinese medicine that is being vigorously promoted in my country. At present, the teaching of acupuncture in Chinese medicine colleges and universities requires a lot of theoretical foundation and sufficient practice. In daily acupuncture learning, students not only need to master the various acupoints of the human body, but also need to practice a lot of acupuncture techniques. The commonly used teaching tools for practice are dummy models, but because the cost of dummy models is high, and the surface material of the dummy is considered for long-term use, the texture is hard, and the feel of students when acupuncture is different from the feeling of real skin piercing. Often, an acupuncture student needs to go to the clinic and do a lot of practice before slowly touching the "threshold", which is also an important reason why Chinese medicine acupuncture is difficult to master. Moreover, because the dummy models are large in size, they are basically provided by the school, so students can only practice during class time, resulting in far less practice time, affecting the quality of acupuncture teaching in Chinese medicine colleges and universities, and it is difficult to train students to a certain level quickly and in large numbers, hindering the development of acupuncture teaching. Summary of the invention

[0004] The present invention provides a simulation training device for acupuncture needle techniques, which has an ingenious and reasonable structural design. It transforms traditional acupuncture practice from a single dummy model into a miniaturized and portable technique training device. Students can memorize the acupuncture point identification of the human body through existing methods, and the present device can train students' acupuncture techniques in a very targeted manner. Students can each have a set of acupuncture techniques without geographical restrictions. They can set the angle and position of acupuncture by themselves according to the system, so as to conduct repeated intensive practice. The present invention is equipped with a qualified acupuncture detection function, so that students can know whether the acupuncture action is completed correctly according to prompts, so that various acupuncture techniques can be simulated, and students can continuously conduct intensive practice. Compared with the existing dummy training, they can quickly master and improve the acupuncture techniques. The cost of the entire device is controllable and the size is small. Students can strengthen their training by themselves in their spare time, simulate different acupuncture techniques, effectively improve the quality of acupuncture teaching, and solve the problems existing in the prior art.
