Description

Technical Field

[0001] The invention relates to medical equipment, in particular to a headrest device used for ear scraping massage in traditional Chinese medicine. Background Art

[0002] Gua Sha is guided by the theory of meridians and acupoints in traditional Chinese medicine. Through the use of special scraping instruments and corresponding techniques, a certain medium is dipped in the body surface to repeatedly scrape and rub, causing local skin changes such as red millet-like or dark red bleeding spots, thereby achieving the effect of activating blood circulation and removing sha.

[0003] Ear scraping is a scraping therapy developed on the basis of holographic biology and holographic scraping therapy. It is based on the biological holographic law - the corresponding relationship between the holographic acupoints of local organs and the internal organs, that is, if they flourish, they all flourish, and if they wither, they all wither. It is a method of diagnosis and treatment based on syndrome differentiation, and through Xu Erhe's technique, a copper plate dipped in a medium is used to scrape the holographic acupoints of the ear, making the skin appear rosy and withering spots. The effect is transmitted through the meridians, thereby regulating the yin and yang balance of the internal organs, and achieving the purpose of preventing and treating diseases.

[0004] The operation steps of ear scraping are as follows: ① Ear massage: To promote the circulation of qi and blood throughout the body, the patient lies flat first, and the operator applies lubricating oil to massage both ears. ② Basic ear scraping: including various parts in front of and behind the ear, the specific scraping direction is from bottom to top, from inside to outside, from earlobe → helix → scaphoid → antihelix → concha cavity → cylindrica auricularis → concha → triangular fossa → front of the ear; the back of the ear is from inside to outside, from bottom to top, from the back of the earlobe → the back of the tail of the helix → the back of the helix → the back of the antihelix → the back of the antitragus → the posterior bulge of the concha cavity → the posterior groove of the helix crus → the posterior bulge of the cylindrica auricularis → the posterior groove of the lower crus of the antihelix → the posterior bulge of the triangular fossa → behind the ear to the sternocleidomastoid muscle. ③ Scrape key parts. According to the selected syndrome type, the brain stem, triple burner, front, occipital, heart, liver, spleen and other acupoints are scraped. For those who have many dreams, the dreaming area is scraped in addition to the key areas. For those who wake up early, the deep sleep point is scraped in addition to the key areas. ④ Alternate scraping of the left and right ears.

[0005] Ear scraping uses brass as a scraping medium, which has the advantages of strong thermal conductivity, sterilization, penetration, and strong energy. The auricle is a miniature of an inverted fetus in the human body. The ear is closely connected with the meridians, internal organs, and limbs. Therefore, by scraping the ear, it can mobilize the body's qi and blood circulation, dredge the meridians of the limbs, and improve the effects of the five internal organs, thereby achieving the effects of awakening the brain, nourishing the marrow, benefiting the heart and calming the nerves, and relieving patients' symptoms of insomnia, tinnitus, dizziness, etc.

[0006] Doctors have found in actual practice that during ear scraping treatment, the height of the headrest will have a great impact on the patient's feeling and the doctor's operation due to the different shoulder widths of the patients. However, the height of the traditional scraping massage headrest cannot be adjusted, which is inconvenient for the doctor's operation.

[0063] The headrest device for ear scraping massage according to the traditional Chinese medicine of the above embodiment of the present invention has the following beneficial effects:

[0064] 1. The headrest can be adjusted up and down, and can also be adjusted left and right. It not only ensures that the doctor can adjust the height of the headrest according to the patient's shoulder width during the operation, but also adjusts the posture of the patient's head according to the operation position and technique, which not only facilitates the doctor's operation, but also improves the patient's comfort.

[0065] 2. The hinge between the hinge rod and the headrest is connected by a ball head, which not only ensures the structural support but also takes into account the smooth tilting of the headrest.

[0066] 3. The scissor lift is driven by a worm gear, which ensures that a relatively small power can drive a high-power work, and also ensures that the worm gear can stop retreating, ensuring the stable and reliable position of the headrest.

[0067] 4. The installation structure of the swing bearing seat of the rotating power shaft and the power shaft not only ensures the rotation of the power shaft, but also allows the power shaft to have room for movement according to the up and down fluctuation of the double-rotation screw rod, and also has an anchoring function for the support arm of the articulated rod, avoiding the left and right swing of the support arm of the articulated rod and achieving the stability of the headrest.

[0068] 5. The sliding spline connection between the driven gear and the power shaft ensures power output and facilitates power blocking. The reset function of the compression spring can make the driven gear and the driving gear reliably meshed, and also ensure that the driven gear automatically resets after power blocking.

[0069] 6. The ball head connection structure of the shift fork rod can make the shift rod swing left and right, and can also achieve fine adjustment of the shift fork up and down along with the end face gear seat.

[0070] 7. The balance gear can make the motor's driving gear and end gear have a better meshing angle.

[0071] 8. The headrest pad adopts the interconnection of rack and gear. When one side moves, the other side moves with it, which is convenient for adjustment.

[0072] 9. The rack stop structure adopts a trip tooth structure, which can be adjusted as desired.

[0073] 10. The ear avoidance holes can provide better space for the ears that have just been scraped to promote blood circulation, thereby ensuring the treatment effect.

[0074] 11. The power is in the form of a battery pack, which avoids the risk of power outages during use, and the device can be moved at will, which is more convenient and safer.

[0075] 12. The use of external elastic stretch fabric can not only make the product more beautiful, but also ensure the free adjustment of the headrest.

[0076] 13. The backrest and pillow on the headrest are made of soft cotton pad material, which effectively reduces the hardness of the rigid structure of the product and makes the patient's head more comfortable when leaning on the pillow during treatment.

[0077] 14. Use disposable disinfected pads during operation to ensure personal hygiene and avoid cross infection.

[0078] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
