Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a portable bloodletting cupping set. Background Technology

[0002] With the popularization of traditional Chinese medicine physiotherapy and the increasing demand for convenient health care methods, portable bloodletting cupping sets, as a tool combining bloodletting therapy and cupping therapy, are widely used in home health care, outdoor first aid, primary healthcare and other occasions. They use bloodletting needles to prick acupoints or lesions, and then use the negative pressure formed by cupping to promote local blood circulation, so as to achieve the effects of promoting blood circulation, removing blood stasis, clearing meridians and relieving pain.

[0003] Existing portable bloodletting cupping sets lack a reliable automatic pressure relief structure when the internal pressure is too high, and manual pressure relief is also cumbersome. This can easily cause excessive suction damage to the skin due to excessive pressure. Furthermore, the sealing components that come into contact with the skin at the cup opening have an unstable connection, which leads to air leakage during cupping, affecting the effect, and are inconvenient to disassemble and replace. It is also difficult to solve the problem of poor sealing caused by the aging of sealing components after long-term use. Therefore, a portable bloodletting cupping set is proposed to solve the above problems. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a portable bloodletting cupping set, aiming to improve the existing technology's lack of automatic pressure relief, cumbersome manual pressure relief, and inconvenient disassembly and replacement of rubber rings.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a portable bloodletting cupping set, including a cupping body and a rubber ring, a pressure relief mechanism is provided inside the cupping body, a fixing mechanism is provided at the bottom of the cupping body, a pressure supply component is provided at the top of the cupping body, a top cover is threaded to the outside of the cupping body, a cork is fixedly connected inside the top cover, multiple bloodletting needles are inserted into the top of the cork, and a blood-absorbing cotton ring is provided inside the rubber ring. The pressure relief mechanism includes a sleeve, the outside of which is fixedly connected to the inside of the tank. A retaining ring is fixedly connected inside the sleeve. A sliding rod is slidably connected inside the sleeve. A spring is sleeved on the outside of the sliding rod. A piston is fixedly connected to one end of the sliding rod. A limit block is fixedly connected to the outside of the sliding rod.

[0006] Preferably, the fixing mechanism includes two insertion holes and two connecting posts. The insertion holes are opened on the top of the rubber ring, and the insertion holes have grooves inside. The connecting posts are fixedly connected to the bottom of the tank, and the connecting posts have convex rings fixedly connected to the outside.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Reference Figures 1-4 This utility model discloses a portable bloodletting cupping set, which includes a cupping body 1 and a rubber ring 8. The cupping body 1 has a pressure relief mechanism inside, a fixing mechanism at the bottom, and a pressure supply component at the top. A top cover 2 is threaded to the outside of the cupping body 1, and a cork stopper 7 is fixedly connected inside the top cover 2. Multiple bloodletting needles 10 are inserted into the top of the cork stopper 7. A blood-absorbing cotton ring 9 is placed inside the rubber ring 8. The pressure relief mechanism includes a sleeve 3, which is fixedly connected to the outside of the cupping body 1. A fixing ring 13 is fixedly connected inside the sleeve 3, and a sliding rod 14 is slidably connected inside the sleeve 3. A spring 12 is fitted on the outside of the slide rod 14. A piston 11 is fixedly connected to one end of the slide rod 14. A limit block 15 is fixedly connected to the outside of the slide rod 14. The pressure supply assembly includes an air extraction pipe 5, which is fixedly connected to the top of the tank 1. A one-way valve 4 is installed inside the air extraction pipe 5. A negative pressure generator 6 is installed at the top of the air extraction pipe 5. One end of the spring 12 is fixedly connected to one side of the fixing ring 13. The other end of the spring 12 abuts against the piston 11. The outside of the slide rod 14 is slidably connected to the inside of the limit block 15. The piston 11 is slidably connected to the inside of the sleeve 3. The outside of the cork 7 is slidably connected to the inside of the absorbent cotton ring 9.

[0021] The jar body 1, as the main structure of the portable bloodletting cupping set, provides a negative pressure adsorption space, provides a mounting base for various parts, and forms the closed space required for cupping. The top cover 2, through a threaded connection to the outside of the jar body 1, stores and protects the internal cork stopper 7 and bloodletting needle 10. The sleeve 3 provides mounting and sliding tracks for the slide rod 14, piston 11, and limit block 15 of the pressure relief mechanism. The one-way valve 4 controls the unidirectional flow of gas, preventing backflow of gas inside the jar body 1 after suction, and ensuring stable negative pressure. The suction pipe 5 is a channel connecting the jar body 1 and the negative pressure generator 6, used to transmit gas to create a negative pressure environment inside the jar body 1. The negative pressure generator 6 generates negative pressure inside the jar body 1 through suction, meeting the requirements of cupping. The cork stopper 7 is used to fix and protect the bloodletting needle 10 inserted at its top. The rubber ring 8 ensures a tight fit between the jar body 1 and the cupping site, preventing air leakage. The absorbent cotton ring 9 absorbs blood after bloodletting, keeping the jar clean. The lancet 10 is used during treatment to prick the skin and release blood. The piston 11, under the action of the spring 12, can move up and down, working with the slide rod 14 to achieve pressure relief inside the canister 1. The spring 12 provides elasticity to the piston 11, keeping it sealed when there is no external force. During pressure relief, deformation allows the piston 11 to move and allow gas to flow. The retaining ring 13 is used to fix one end of the spring 12 and limit the range of movement of the piston 11. The slide rod 14 drives the piston 11 to slide within the sleeve 3, achieving pressure relief control. The limiting block 15 is used to limit the sliding stroke of the slide rod 14, preventing it from falling out of the sleeve 3.

[0022] Reference Figure 2 and Figure 4 The fixing mechanism includes two insertion holes 16 and two connecting posts 18. The insertion holes 16 are opened on the top of the rubber ring 8, and the groove 17 is opened inside the insertion holes 16. The connecting posts 18 are fixedly connected to the bottom of the tank body 1, and the outer side of the connecting posts 18 is fixedly connected to the protrusion 19. The bottom of the rubber ring 8 abuts against the top of the top cover 2, and the top of the rubber ring 8 abuts against the bottom of the tank body 1. The outer side of the connecting posts 18 is inserted into the insertion holes 16, and the outer side of the protrusion 19 is engaged in the groove 17.

[0023] The insertion hole 16 is used to accommodate the connecting post 18, and cooperates with the connecting post 18 to achieve quick positioning and installation of the rubber ring 8. The groove 17 and the convex ring 19 are interference-fitted to enhance the connection stability between the connecting post 18 and the insertion hole 16, prevent the rubber ring 8 from falling off, and fix the rubber ring 8 to the bottom of the tank body 1. The connecting post 18 fixes the rubber ring 8 to the bottom of the tank body 1 through the cooperation of the convex ring 19 and the groove 17.

[0024] The working principle is as follows: When using, first remove the top cover 2 that is threaded to the can body 1, take out the lancet 10 from the top of the cork 7, use the lancet 10 to prick the treatment area, and then make the bottom of the rubber ring 8 fit tightly against the skin to ensure that the absorbent cotton ring 9 is in contact with the treatment area. Air is drawn from inside the cupping jar 1 via the suction pipe 5 using the negative pressure generator 6. The one-way valve 4 prevents backflow of gas, creating a stable negative pressure environment inside the jar 1. Under this negative pressure, the skin tissue bulges, causing bleeding at the puncture site. The absorbent cotton ring 9 inside the rubber ring 8 absorbs the blood, keeping the jar clean. During cupping, if the pressure inside the jar becomes too high, the pressure relief mechanism automatically activates. The sliding rod 14 slides inside the sleeve 3, moving the piston 11. The spring 12 deforms due to the movement of the piston 11, allowing gas to flow and reducing the pressure inside the jar. The limiting block 15 restricts the sliding of the sliding rod 14, preventing it from falling out of the sleeve 3. After the pressure returns to normal, the spring 12 pushes the piston 11 back to its original position, keeping the jar 1 sealed. In case of emergency pressure relief, the sliding rod 14 can be manually pushed to move the piston 11 for rapid gas release. After treatment, the absorbent cotton ring 9 is removed and a new one installed for future use. After long-term use, when the rubber ring 8 ages or the seal is not good, pull the connecting post 18 out of the insertion hole 16, so that the convex ring 19 is disengaged from the groove 17, remove the old rubber ring 8 and replace it with a new one, and snap the new rubber ring 8 into the groove 17 through the outside of the convex ring 19, so that the outside of the connecting post 18 is inserted into the insertion hole 16, thereby ensuring that the rubber ring 8 is firmly fixed to ensure the sealing and use effect during cupping.
