Abstract
Description
Technical Field
[0001] This utility model relates to the field of rehabilitation and physiotherapy technology, specifically a negative pressure cupping device. Background Technology
[0002] Cupping, a traditional Chinese therapy, stands out in the field of rehabilitation therapy due to its unique negative pressure effect. Cupping has unique effects in promoting blood circulation, relieving muscle tension, and enhancing immunity. Through negative pressure, cupping can draw out dampness and cold from the body, while simultaneously promoting local blood circulation and accelerating the resolution of inflammation.
[0003] Negative pressure cupping usually has magnetic needles installed inside to stimulate acupoints. Existing magnetic needles are slidably installed inside the negative pressure cupping jar, and the pressure of the telescopic spring is used to avoid discomfort caused by excessive pressure from the magnetic needles. However, the skin laxity of the users varies, especially for obese people. Under the negative pressure of the cupping jar, the height of the skin tissue bulges is different, and the pressure will increase with the contraction length of the telescopic spring, which will also produce a needle-like sensation.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0022] This utility model embodiment provides a negative pressure cupping device, such as... Figure 1-2 As shown, the device includes a transparent tank 1, a vent valve stem 2, and a sealing plug 3. An installation tube 4 is integrally formed on the top of the transparent tank 1. An inner concave ring is provided along the inner wall of the installation tube 4. The installation tube 4 extends to both the inner and outer sides of the transparent tank 1, allowing communication between the inside and outside of the transparent tank 1. The vent valve stem 2 slides through the installation tube 4. A sealing valve block 5 is provided at the lower end of the vent valve stem 2. The inner diameter of the sealing valve block 5 is smaller than the inner diameter of the installation tube 4, and the inner diameter of the inner concave ring is smaller than the outer diameter of the sealing valve block 5. The positioning of the vent valve rod 2 can be used to prevent negative pressure suction from causing the vent valve rod 2 to slide out from the upper side of the mounting tube 4. The lower end of the sealing valve block 5 is provided with an abutting cone. The lower end of the mounting tube 4 is integrally formed with a threaded sleeve 6. The threaded sleeve 6 is set inside the transparent tank 1. The sealing plug 3 is inserted into the bottom of the threaded sleeve 6. The middle part of the sealing plug 3 is provided with a connecting hole. The top of the sealing plug 3 is provided with a sealing cone groove that matches the abutting cone. The sealing valve block 5 abuts in the sealing cone groove to form a sealing effect.
[0023] The threaded sleeve 6 is fitted with a magnetic needle sleeve 7, which is made of transparent material. The sliding part of the magnetic needle sleeve 7 has scale lines on its side wall, which can be observed through the transparent can and the transparent magnetic needle sleeve 7.
[0024] The magnetic needle sleeve 7 includes an integrally formed helical ring portion 71, a spline portion 72, and a sliding portion 73 from top to bottom. The helical ring portion 71 is threadedly sleeved on the threaded sleeve 6. The height of the magnetic needle sleeve 7 can be adjusted by rotating the magnetic needle sleeve 7 through the threaded engagement.
[0025] An inner beam ring 8 is provided between the spline part 72 and the sliding part 73. The lower end of the sliding part 73 is slidably connected to a sliding magnetic seat 9. A magnetic needle block 10 is fixed to the lower end of the sliding magnetic seat 9. A telescopic spring 11 is connected between the sliding magnetic seat 9 and the inner beam ring 8. The telescopic spring 11 can buffer the magnetic needle block 10 against the raised skin tissue, avoiding direct pricking of the skin during cupping. A venting groove is provided on the side wall of the sliding part 73. The venting hole, the inner ring of the inner beam ring 8, the connecting hole and the mounting tube 4 are connected to the outside, which can draw out the air inside the transparent canister 1 to form a negative pressure.
[0026] The inner wall of the splined part 72 is provided with several spline grooves 12. An extension beam 13 is provided at the lower end of the sealing valve block 5. The diameter of the extension beam 13 is smaller than the inner diameter of the connecting hole, forming an airflow channel between the extension beam 13 and the connecting hole to facilitate airflow during intake. A spline wheel 14 is provided at the lower end of the extension beam 13. Several spline sliders are provided on the outer wall of the spline wheel 14. The spline sliders are slidably installed in the spline grooves 12 with a convex-concave fit. The length of the spline groove 12 is greater than... The thickness of the spline wheel 14, the spline slider and the spline groove 12 form a mutual locking limit, the rotation of the spline wheel 14 can drive the magnetic needle sleeve 7 to rotate together, so that the screw ring part 71 can move up and down in the threaded sleeve 6, the spline slider can slide up and down in the spline groove 12, and the spline wheel 14 can be kept at the original height during the rotation and upward movement of the magnetic needle sleeve 7, so as to avoid the magnetic needle sleeve 7 pushing the vent valve rod 2 upward during the upward movement, causing a gap between the sealing valve block 5 and the sealing plug block 3 and causing pressure leakage.
[0027] The inner wall of the spline wheel 14 is provided with a positioning ring 15. The outer diameter of the positioning ring 15 is smaller than the inner diameter of the connecting hole. The positioning ring 15 is fixed to the lower end of the extension beam 13. The spline wheel 14 is provided with several ventilation openings 16 to prevent air extraction from causing the spline wheel 14 to move upward and collide with the sealing plug 3 to block the connecting hole.
[0028] Working principle:
[0029] In this invention, during the cupping process, air is drawn out of the transparent canister 1 through the suction from the upper mounting tube 4. The airflow pushes the sealing valve block 5 upward and separates it from the sealing plug 3, allowing the interior of the transparent canister 1 to connect with the outside through the venting slot, the inner ring of the inner beam ring 8, the venting opening 16, the gap between the connecting hole and the extension beam 13, and the mounting tube 4. This draws out air, creating a negative pressure inside the transparent canister 1. The negative pressure presses the sealing valve block 5 tightly against the upper side of the sealing plug 3, sealing the connecting hole and sealing the interior of the transparent canister 1, thus performing negative pressure cupping.
[0030] Under negative pressure, the skin tissue will bulge upwards on the lower side of the transparent jar 1 and press against the lower side of the magnetic needle block 10, which will compress the telescopic spring 11 and provide a buffer between the magnetic needle block 10 and the bulging skin tissue. When the pressure of the magnetic needle block 10 on the skin tissue is too great and causes stinging, the vent valve rod 2 can be rotated to rotate the magnetic needle sleeve 7 through the spline wheel 14. Through the threaded engagement between the screw ring part 71 and the threaded sleeve 6, the height of the magnetic needle sleeve 7 in the transparent jar 1 can be adjusted, and the relative position of the sliding magnetic seat 9 and the scale line can be directly observed through the transparent jar 1 and the transparent magnetic needle sleeve 7 to control the pressure of the magnetic needle block 10 on the skin tissue.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
