Technical Field

[0001] The invention belongs to the technical field of vacuum cupping equipment, and in particular relates to a cupping device for traditional Chinese medicine nursing and rehabilitation. Background Art

[0002] Cupping therapy, an essential component of traditional Chinese medicine external treatments, has a history of over 2,000 years. It stimulates acupuncture points through physical negative pressure, achieving the therapeutic effects of "unblocking meridians, promoting qi and blood circulation, reducing swelling and pain, and dispelling wind and cold." With the development of modern rehabilitation medicine, the limitations of traditional cupping devices in terms of safety, precision, and functional integration have become increasingly apparent.

[0003] Existing cupping devices mostly use vacuum cupping. For example, patent application number CN95229903.8, titled "Vacuum Cupping," utilizes a suction cup, a rubber joint, and a vacuum gun. The gun consists of a cylinder, a pull handle, a spring, a pumping piston, a rubber ring, and a handle. This application utilizes the pull handle to repeatedly extract air from the cylinder, effectively allowing the cup to adhere to the body's surface. This requires multiple operations with the vacuum gun, preventing it from being applied immediately. Furthermore, the gun is relatively long, making it difficult to store. Furthermore, vacuum cupping requires the use of electrical power. Summary of the Invention

[0004] In view of the above situation, in order to reduce the number of vacuum cupping operations, shorten the length of the cupping equipment, make the equipment occupy a smaller area when stored, and reduce the dependence of the cupping equipment on electrical equipment, the present invention provides a cupping device for traditional Chinese medicine nursing and rehabilitation, which significantly improves the negative pressure adsorption force generated by a single operation, achieves the design effect of instant adsorption on the body surface in one operation, changes the structure of the vacuum cupping device, and shortens the length of the cupping equipment.

[0021] like Figure 1-Figure 7 As shown, the present invention provides a cupping device for traditional Chinese medicine nursing and rehabilitation, including a suction cup 1 and a vacuum booster gun 2.

The finger pressure groove 8 is arranged in the gun housing 3, the finger pressure plate 7 slides horizontally along the finger pressure groove 8, the driving rack 9 is fixedly mounted on the finger pressure plate 7, the driving rack 9 slides horizontally along the finger pressure groove 8, the reverse ratchet 10 is fixedly arranged on the driving rack 9, the limiting ratchet 11 is in contact with and connected to the reverse ratchet 10, the limiting ratchet 11 slides on the side wall of the finger pressure groove 8, and the ratchet adjustment plate 12 is fixedly connected to the limiting ratchet 11 through a bracket.

[0023] The reverse ratchet 10 and the limit ratchet 11 are both arranged in the shape of an obtuse triangle, with two groups of obtuse sides being parallel to and in contact with each other.

[0024] The finger pressure plate 7 is connected to the gun housing 3 by a spring, and a spring is also provided between the ratchet adjustment plate 12 and the gun housing 3.

[0025] The speed increasing and boosting structure 4 includes a transmission adjustment device 13 and a proportional speed increasing device 14. The proportional speed increasing device 14 is snap-fitted and installed in the gun housing 3. The transmission adjustment device 13 is connected to the finger pressure limit device 5; the transmission adjustment device 13 includes a driving gear 15, a bevel gear 16, a connecting bracket 17, a bevel gear 2 18, and a transmission gear 19. The driving gear 15 is engaged with the driving rack 9, and the bevel gear 16 is fixedly connected to the driving gear 15 through the connecting bracket 17. The bevel gear 2 18 is engaged with the bevel gear 16, and the transmission gear 19 is fixedly connected to the bevel gear 2 18.

[0026] The proportional speed increasing device 14 includes a gear ring 20, a transmission gear 2 21, a three-phase bracket 22, a three-phase gear 23, a center gear 24 and an external transmission gear 25. The gear ring 20 is fixedly arranged in the gun housing 3, the transmission gear 2 21 is engaged with the transmission gear 1 19, the three-phase bracket 22 is fixedly installed on the center of the transmission gear 2 21, the three-phase gear 23 is engaged and rotated along the inner wall of the gear ring 20, and the three-phase gear 23 is engaged and rotated on the three-phase bracket 22, the center gear 24 is engaged with the three-phase gear 23, and the external transmission gear 25 is fixedly connected to the center gear 24 through the bracket.

[0027] The central gear 24 is arranged concentrically with the ring gear 20 .

[0028] A piston 26 is provided in the air cylinder 6 , a bracket is provided on the piston 26 , a rack is provided on the bracket, and the rack is meshed with an external transmission gear 25 .

[0029] The bottom of the air cylinder 6 is set to a conical structure, and a sealing ring made of rubber material is provided at the connection between the air cylinder 6 and the suction can 1.

[0030] The gun housing 3 is provided with a scale, and the gun housing 3 is provided with a slot 27 , which is connected to the finger pressure groove 8 , and a locking and sliding limit column 28 is provided in the slot 27 .

[0031] When in use, place the suction cup 1 on the body surface, estimate the suction force required for the patient based on the patient's age and skin laxity, and insert the limit post 28 on the corresponding scale according to the required suction force. The limit post 28 falls from top to bottom on the moving track of the drive rack 9; To start the cupping operation, the thumb presses the acupressure plate 7, driving the rack 9 to slide deeper into the acupressure groove 8. Each time the reverse ratchet 10 on the driving rack 9 contacts the limiting ratchet 11, the limiting ratchet 11 slides away from the acupressure groove 8. After the driving rack 9 contacts the limiting post 28, the thumb leaves the acupressure plate 7. The spring on the acupressure plate 7 provides an outward pulling force to the driving rack 9, but the driving rack 9 is restricted by the limiting ratchet 11 and cannot move, so that the suction force of the suction cup 1 is stable. When the driving rack 9 moves, it meshes with the driving gear 15. The rotation of the driving gear 15 drives the bevel gear 16 to rotate. The kinetic energy is transmitted through the bevel gear 2 18 and the transmission gear 1 19, causing the transmission gear 2 21 to rotate. The transmission gear 2 21 uses the three-phase bracket 22 to make the three-phase gear 23 rotate with the transmission gear 2 21 as the center. Since the three-phase gear 23 is meshed with the gear ring 20, the three-phase gear 23 rotates. During the rotation of the three-phase gear 23, the center gear 24 rotates at the center position of the gear ring 20, and the external transmission gear 25 rotates under the drive of the center gear 24. Since the rotation speed of the center gear 24 is proportionally amplified by the transmission gear 2 21, the rotation speed of the external transmission gear 25 is faster, and the sliding distance of the rack where the piston 26 is located is longer, achieving the design effect that the suction cup 1 is instantly adsorbed on the body surface under a single press; The vacuum booster gun 2 is pulled out from the suction cup 1. Under the action of external air pressure, the plug on the suction cup 1 is pressed downward by the air pressure, thereby sealing the suction cup 1 and fixing the suction cup 1 on the body surface.

[0032] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
