Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a cupping device capable of flexibly adjusting the pressure inside a cup. Background Art

[0002] Cupping therapy, an ancient art of Traditional Chinese Medicine, has long transcended China, becoming a global practice and considered a culmination of Chinese medical wisdom. The procedure involves placing specially designed cups on key acupuncture points or areas of discomfort. A negative pressure is created within the cups by either vacuuming or burning air, allowing them to adhere tightly to the skin. This tight adhesion, which causes localized redness or blood spots on the skin, is the mechanism by which cupping exerts its therapeutic effects. By promoting vasodilation and blood circulation, it delivers essential nutrients and oxygen to the affected area, while also assisting in the elimination of waste products and accelerating recovery.

[0003] Air cupping and fire cupping are two different types of cupping therapy. The main difference between them is the different ways of forming negative pressure. Fire cupping is a traditional cupping method that uses a flame (such as an alcohol cotton ball) to burn the air in the cup, thereby forming negative pressure. The adsorption force of the fire cup is strong, but it requires certain skills to operate. In addition, the fire cupping can produce a certain warm stimulation to the skin, which helps to promote blood circulation. Air cupping is a modern cupping method that uses a vacuum pump to extract the air in the cup to form negative pressure. The adsorption force of the air cup can be controlled by adjusting the vacuum pump. However, due to the principle and design limitations of the air cup, the material of the air cup is often plastic, and it is difficult to produce the warm stimulation that the fire cup can produce on the skin by heating. Therefore, there is a need for a cupping device that can not only adjust the adsorption force more accurately, but also heat the cup body with a flame to produce warm stimulation to the skin, so as to achieve better results. Utility Model Content

[0004] In order to solve the above technical problems, the utility model designs a cupping device that can flexibly adjust the pressure inside the cup. The cup body can be heated according to the principle of fire cupping and then placed on the skin to form negative pressure. The air pressure inside the cup can then be adjusted by a pressure regulating device. In addition, there is an exhaust device to facilitate pressure relief and remove the cup body.

[0005] In order to achieve the above technical effects, the utility model is realized by the following technical solutions: a cupping device for flexibly adjusting the pressure inside the cup, comprising: a glass cup body, a sealing gasket, a piston gasket, an upper cover, a pressure relief valve, a spring, and a screw cap;

The upper cover is tightened with the glass jar body through threads, and the screw cap is rotatably fitted on the top of the upper cover through a slot. The spring is sleeved on the outside of the pressure relief valve, and the pressure relief valve is slidably mounted on the inside of the screw cap.

[0007] Furthermore, the piston gasket includes two layers of circular plates, a bolt column, and a fixed shaft. Five cylinders are fixedly connected between the two layers of circular plates. Rubber rings are covered on the outsides of the circular plates on both sides. A bolt column is located in the middle of the top circular plate. The fixed shafts are symmetrically fixed on both sides of the bolt column. The fixed shaft is a cylindrical structure with another large disc fixed on the top of the cylinder.

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Example 1

[0023] The utility model discloses a cupping device which can flexibly adjust the pressure inside the cup, comprising: a glass cup body 1, a sealing gasket, a piston gasket, an upper cover, a pressure relief valve, a spring, and a screw cap. Figure 2 As shown, the sealing gasket is sleeved on the outside of the glass jar body, the piston gasket is slidably fitted on the inside of the upper cover, the upper cover is tightened with the glass jar body through threads, the screw cap is rotatably fitted on the top of the upper cover through a slot, the spring is sleeved on the outside of the pressure relief valve, and the pressure relief valve is slidably installed on the inside of the screw cap.

[0024] Example 2

[0025] In this embodiment, if Figure 5As shown, the glass jar body 1 is a circular structure with openings at both ends. One end is a bottle-mouth-like flat surface that can fit the skin, and the other end has threads. This structure can be fired out of glass material, so that the jar body can be heated with a flame when in use, ensuring the same pressure and warming effect as a cupping jar. In addition, a sealing gasket 2 is provided on the threaded mouth to ensure the sealing of the glass jar body 1 and the upper cover 3 when they are matched. The detachable structure facilitates the cleaning and disinfection of the jar body to ensure medical hygiene.

[0026] Example 3

[0027] In this embodiment, if Figure 5 As shown, the piston gasket 6 includes two layers of circular plates, bolt columns, and fixed shafts. There are five cylinders fixedly connected between the two layers of circular plates. Rubber circles are covered on the outside of the circular plates on both sides. The air tightness of the cavity is ensured by the double sealing of the circular plates on both sides. There is a bolt column in the middle of the top circular plate. The fixed shafts are symmetrically fixed on both sides of the bolt column. The fixed shaft is a cylindrical structure. Another large disc is fixed on the top of the fixed shaft. There is a circular hole running through the middle of the bolt column and the circular plates on both sides.

[0028] Example 4

[0029] In this embodiment, the upper cover 3 is a cylindrical structure with an opening on one side and a thread on the inside, which can be tightened with the threaded opening of the glass jar body 1. The other end of the upper cover 3 is flat, with a circular opening in the middle and a cylindrical step opening on the outside of the circular opening. The step opening can buckle the screw cover 4. There are two small circular holes on both sides of the circular opening. The two fixed shafts on the piston gasket are slidably fitted on the circular holes. Through the fixed shaft, it can be ensured that there is only relative sliding between the upper cover 3 and the piston gasket 6, and no relative rotation.

[0030] Example 5

[0031] The outer periphery of the screw cap 4 is provided with a vertical stripe pattern structure, which can be easily rotated by hand to reduce friction; when the screw cap 4 is rotated clockwise, the piston gasket 6 will move upward, at this time the internal volume of the tank body becomes larger, and the air pressure in the tank body decreases; when the screw cap 4 is rotated counterclockwise, the piston gasket 6 will move downward, at this time the internal volume of the tank body becomes smaller, and the air pressure in the tank body increases. By rotating the screw cap, the pressure in the tank body can be flexibly adjusted.

[0032] Example 6

[0033] Furthermore, the pressure relief valve 5 is a cylindrical structure, with a rubber disc at the bottom of the cylinder, the spring 7 being sleeved on the outside of the middle section of the cylinder, and a small circular hole at the top, in which a hanging rope or an iron ring can be installed to facilitate pulling. Through the cooperation of the elasticity of the spring 7 and the atmospheric pressure, it can be ensured that the rubber disc always blocks the hole at the top of the bolt column of the piston gasket 6, thereby ensuring the sealing of the can body. When the cupping is completed, due to the existence of the air pressure difference, some cans may be adsorbed very tightly. At this time, the pressure relief valve 5 can be pulled upward, and the outside air can enter the can body through the hole in the piston gasket 6, so that the air pressure inside the can body returns to the atmospheric pressure, making it convenient to quickly remove the cupping.

[0034] Example 7

[0035] The utility model discloses a cupping device that can flexibly adjust the pressure inside the cup. The specific working principle and process are as follows:

[0036] Before using the cupping, the glass jar body 1 can be rotated down for cleaning and disinfection to ensure the hygiene of the medical device. After disinfection and reinstalling the glass jar body 1, twist the screw cap 4 clockwise until the piston gasket 6 reaches the top and the screw cap 4 can no longer be rotated. Then, rotate the screw cap 4 counterclockwise for several turns (a specific number of turns can be obtained according to the actual number of thread turns) to ensure that the piston gasket 6 is located in the middle of the upper cover assembly 3, ensuring that the piston gasket 6 can move up and down in subsequent operations. At this time, you can ignite the alcohol cotton ball and quickly put the ignited cotton ball on the glass jar body 1. Rotate the inner cap 4 several times to expel the air in the cup. At the moment the flame goes out, quickly buckle the cupping cup on the pre-selected part, and use the pressure difference between the air in the cup and the atmospheric pressure to adsorb the cup body on the skin. At this time, you can rotate the screw cap 4 as needed. If you need to increase the adsorption force, turn the screw cap 4 clockwise. If you need to reduce the adsorption force, turn the screw cap 4 counterclockwise. When the cupping time is up, hold the cup body with one hand and pull up the pressure relief valve 5 with the other hand. At this time, the air pressure in the cup body is balanced with the outside world, and the cupping cup can be easily removed. After letting go, the pressure relief valve is pushed back to its original position by the elastic force of the spring 7 to block the air hole.

[0037] In summary, the utility model designs a cupping device that can flexibly adjust the pressure inside the cup. The device can use flames to heat the glass cup body, thereby generating negative pressure and bringing a warm stimulation effect. It overcomes the limitation that traditional gas cups cannot be heated, helps to promote local blood circulation, and has the effects of warming meridians, dispelling cold air and unblocking blood vessels. In addition, the device is also equipped with a pressure regulating mechanism. By rotating the screw cap, the user can adjust the volume of the cavity inside the cup according to treatment needs, and then control the pressure level inside the cup, solving the problem that traditional fire cupping cannot adjust the pressure. The device is also specially designed with a quick pressure relief valve. Through this function, the pressure inside the cup can be quickly balanced to atmospheric pressure, making it easy to remove the cup body quickly and safely.
