Description

Technical Field

[0001] This utility model belongs to the field of cupping technology, and in particular relates to a cupping method with controllable pressure. Background Technology

[0002] Cupping is a traditional Chinese medicine therapy with a long history and is widely used in clinical practice. Cupping uses cups as medical instruments, where the gas inside the cup is burned or extracted to create negative pressure, causing the cup to adhere to specific areas of the body surface, resulting in local subcutaneous congestion to achieve health maintenance or therapeutic effects. The cups are the main tools used in the cupping process.

[0003] A search revealed a negative pressure bloodletting cupping jar with publication number CN220424275U, comprising a jar body, a movable rod, and a stopper. The top of the jar body is equipped with an installation tube. Although the above product can prevent the turbulent flow of blood stasis during use, the negative pressure is uncontrollable. When the pressure is too high, it can easily cause injury to the human body. Therefore, a cupping jar with controllable pressure is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a pressure-controllable cupping device. When the pressure inside the cupping device is too high, air can enter the device through a safety tube to maintain stable pressure and improve safety. Simultaneously, rotating the threaded rod changes the pressure of the second spring, thereby adjusting the pressure inside the device. This device is easy to use. Furthermore, moving the threaded rod moves the sealing gasket, allowing air to quickly enter the device, facilitating the quick and safe removal of the device. This invention solves the existing technical problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] A pressure-controllable cupping device includes: a cupping body, a safety tube fixedly connected to one side of the cupping body, a positioning ring fixedly connected to one end of the safety tube, a fixing frame fixedly connected to the inner circumference of the safety tube, a threaded rod movably connected to one side of the fixing frame, a sealing gasket for cooperating with the positioning ring fixedly connected to the circumference of the threaded rod, a sliding plate slidably connected to the inner circumference of the safety tube, the threaded rod threaded through the sliding plate, and a second spring installed between the sliding plate and the fixing frame. When the pressure inside the cupping body is too high, air can enter the cupping body through the safety tube to maintain the pressure stability inside the cupping body and improve the safety of use.

[0007] A gas outlet mechanism is provided at the top of the tank for venting gas from inside the tank.

[0008] As a further embodiment of this utility model, the air outlet mechanism includes an air extraction pipe, which is fixedly connected to the top of the tank. A limit ring is fixedly connected to the inner circumference of the air extraction pipe. A through guide rod is movably connected to the top of the air extraction pipe. A plug is fixedly connected to the bottom of the guide rod. A third spring is fixedly connected between the inner wall of the top of the air extraction pipe and the plug. Multiple air outlet holes are provided at the top of the air extraction pipe.

[0009] As a further embodiment of this utility model, a limiting groove is provided at the end of the positioning ring away from the safety tube, and an end cap is fixedly connected to one end of the threaded rod. The end cap is located in the limiting groove, and multiple air inlet holes are provided on one side of the end cap for air intake. Pressing the end cap causes the end cap to move the threaded rod and the sealing gasket, thereby allowing air to quickly enter the tank and making it easy to remove the tank.

[0010] As a further embodiment of this utility model, a pointer is fixedly connected to the outer circumference of the end cap, and one end of the positioning ring is provided with a scale line for use with the pointer. The scale line and the pointer work together to facilitate people's observation of the rotation angle of the end cap.

[0011] As a further improvement of this invention, a rubber ring is installed around the circumference of the air extraction pipe.

An absorbent cotton ring is provided on the outer circumference of the sliding sleeve.

[0013] In this application, during use, the canister is placed at the desired cupping location. Then, an air extraction device is used to draw air into the canister through the extraction pipe. During extraction, the plug moves upward under the negative pressure above, drawing out the gas and creating negative pressure inside the canister for cupping. When the pressure inside the canister exceeds the set value, the sealing gasket moves away from the positioning ring, allowing air to enter the canister through the safety tube, maintaining stable pressure and improving safety. To adjust the pressure inside the canister, the end cap is rotated before use. The end cap rotates the threaded rod, which in turn moves the sliding plate, changing the pressure of the second spring. This is convenient and quick. After cupping, pressing the end cap moves the threaded rod and sealing gasket, allowing air to quickly enter the canister for easy removal. When blood or other liquids are present inside the canister, the sliding sleeve and absorbent cotton ring are moved downwards, bringing the absorbent cotton ring into contact with the body. A gap is then created in the canister, allowing the liquid to flow out and be absorbed by the absorbent cotton ring. After absorption, the cotton ring is removed and replaced. This method is convenient to use.

[0014] The embodiments of this utility model have the following beneficial effects:

[0015] In this invention, by installing a safety tube on one side of the tank, air can enter the tank through the safety tube when the pressure inside the tank is too high, thus maintaining the stability of the pressure inside the tank and improving the safety of use. At the same time, rotating the threaded rod can change the pressure of the second spring, thereby adjusting the pressure inside the tank, making it convenient to use.

[0016] In this invention, the threaded rod is designed to slide, so that after the cupping operation is completed, the threaded rod can be moved to move the sealing gasket, thereby allowing air to quickly enter the cupping jar, making it easy to remove the jar quickly and safely.

[0017] In this invention, when the pressure inside the tank is too high, air can enter the tank through the safety tube to maintain the pressure inside the tank and improve the safety of use.
