[0002] The mechanism of bloodletting therapy is to adjust Yin and Yang, dredge the meridians, and harmonize Qi and blood, thereby changing the pathological changes of poor Qi and blood circulation in the meridians and thus adjusting the functions of the internal organs. Bloodletting therapy is a unique acupuncture treatment method within the scope of traditional Chinese medicine and is one of the most commonly used treatment methods in clinical practice of traditional Chinese medicine. Bloodletting therapy has the effects of clearing heat, reducing swelling, detoxifying, relieving pain, promoting blood circulation and removing blood stasis, and calming the nerves. It can balance Yin and Yang, unblock the meridians, eliminate pathogenic factors and restore health, and harmonize Qi and blood. Clinically, it can treat a variety of diseases such as gout, cardiovascular and cerebrovascular diseases, hypertension, diabetes, rheumatoid arthritis, limb numbness, spleen and stomach disharmony, dampness, ophthalmological diseases, skin diseases, andrological and gynecological diseases, herpes zoster, acne, urticaria, headache, hemiplegia after stroke, lumbar disc herniation, cervical spondylosis, tennis elbow, bronchial asthma, stye, hiccups, trigeminal neuralgia, erysipelas, etc., and its treatment scope covers multiple disciplines such as internal medicine, surgery, pediatrics, and obstetrics and gynecology.

[0003] However, existing bloodletting therapies mainly pose the problem of cross-infection with infectious diseases (including hepatitis A, hepatitis B, hepatitis C, syphilis, AIDS, etc.), as well as the high-risk invasive procedures involved in bloodletting. In addition, the bloodletting devices used in bloodletting can effectively reduce the risk of infection by using disposable instruments. However, these devices are modular in structure, which has high manufacturing costs, and the purchase cost for users is also relatively high. Summary of the Invention
