Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cupping auxiliary tools, in particular to a cupping device. Background Art
[0002] Cupping is a traditional Chinese medical method, which uses cups as the main tool. In the old days, negative pressure was generated in the cup by burning fire, so that the cup was adsorbed on the body surface, causing local blood stasis, so as to achieve the effects of dredging meridians, promoting qi and blood circulation, reducing swelling and relieving pain, and dispelling wind and cold. With the development of modern manufacturing technology, most of the current cupping jars are equipped with a one-way valve in the jar to complete the generation of negative pressure by means of air extraction. The device used for air extraction is called a cupping device, which is usually a separate device that can be separated from the jar body so that multiple cups can be separately air-extracted. Because the cupping device is easy to operate, cupping, a treatment method that previously required the operation of a doctor, has now become a means for patients to treat themselves according to the location of the pain. However, because the pain treatment location is sometimes in the back and other parts, these parts are difficult for the patient to reach, and it is difficult to operate the treatment by the existing cupping device by themselves, and it must be helped by others, which causes inconvenience in use. Utility Model Content
[0003] Therefore, the technical problem to be solved by the utility model is to overcome the defect that the cupping device in the prior art is difficult to treat the back and other parts by itself.
[0004] In order to solve the above technical problems, the present application provides a cupping device, including a rubber air-evacuation bag, a main rod and a pressure rod. A handle is provided at one end of the main rod, and a four-bar linkage is provided at the other end of the main rod. The main rod constitutes a connecting rod in the four-bar linkage. The four-bar linkage forms a parallelogram structure. The bag body of the rubber air-evacuation bag is clamped in the frame of the four-bar linkage. The pressure rod is rotatably connected to the handle. One end of the pressure rod is rotatably connected to a linkage rod, and the linkage rod is rotatably connected to the swinging part of the four-bar linkage. When the pressure rod rotates toward the handle, the pressure rod pulls the linkage rod to transform the four-bar linkage into a flattened structure.
[0005] Furthermore, the cross section of the capsule is circular and abuts against each link of the four-bar linkage.
[0006] Furthermore, a pressure plate for increasing the contact area is provided at the contact point between each link of the four-bar linkage and the capsule.
[0007] Furthermore, a slot is provided on the capsule body, and the pressure plate is embedded in the slot.
[0008] Furthermore, the slot is an annular groove arranged around the capsule body, each pressing plate has the same height, and both ends of the top and bottom of each pressing plate are embedded in the slot.
[0009] Furthermore, two flanges are arranged in parallel on the capsule body; the two flanges protrude from the outer surface of the capsule body, thereby forming a clamping groove.
[0010] Furthermore, the four-bar linkage, the pressure rod and the linkage rod are all located on the same side of the main rod.
[0011] Furthermore, the rubber air pumping bag is detachably connected to the four-bar linkage, and the rubber air pumping bag can be connected to the four-bar linkage after being reversed.
[0012] By adopting the above technical solution, the utility model has the following technical effects:
[0013] The cupping device provided by the utility model is provided with a main rod, thereby extending the user's arm, so that the cupping cup can be delivered to an area that is usually out of reach. And by providing a pressure rod and a linked four-bar linkage, the user does not need to cooperate with both hands, but can complete the air pumping action of the rubber air bag by holding it tightly with one hand, which is simple and quick to operate. Moreover, when the four-bar linkage forming a parallelogram structure is in a flattening movement, the connecting rods on each opposite side can always maintain a parallel posture, so that when squeezing the rubber air bag, the rubber air bag will not be tilted due to the non-parallel pushing of the bag body by the rods on both sides, so that during the air pumping and squeezing process, the cupping cup is guaranteed not to be misaligned or tilted and leaking, and the plugging of the cupping cup and the rubber air bag is always maintained in a stable and leak-proof reliable state.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0023] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0024] This embodiment provides a cupping device. In one embodiment, Figures 1 to 3 As shown, it includes a rubber air bag 2, a main rod 4 and a pressure rod 6. A handle 5 is provided at one end of the main rod 4, and a four-bar linkage is provided at the other end of the main rod 4. The main rod 4 constitutes one of the connecting rods in the four-bar linkage, and the other three are Figure 1The first connecting rod 1, the second connecting rod 8 and the third connecting rod 9 in the four-bar linkage form a parallelogram structure. The rubber air-extraction bag 2 is a prior art device, which is the most widely used cupping device at present. It includes a bag body 11 and an air-extraction port 14 and an air-exhaust port 10 located at both ends of the bag body 11. A one-way valve is arranged in the air-extraction port 14. The air-extraction port 14 is plugged into the fire cup and cooperates with the one-way valve in the cup, so that the gas in the cup can flow out in one direction when the bag body 11 is repeatedly squeezed. After the air is exhausted, the air-extraction port 14 is separated from the fire cup. The bag body 11 of the rubber air-extraction bag 2 is clamped in the frame of the four-bar linkage, and the pressure rod 6 is rotatably connected to the handle 5. One end of the pressure rod 6 is rotatably connected to the linkage rod 7. The linkage rod 7 is rotatably connected to the swinging part of the four-bar linkage, and the swinging part of the four-bar linkage is the first connecting rod 1, the second connecting rod 8 or the third connecting rod 9, which can swing relative to the main rod 4. When the pressure rod 6 rotates toward the handle 5 , the pressure rod 6 pulls the linkage rod 7 to transform the four-bar linkage into a flat structure.
[0025] When in use, the device first inserts a cupping jar into the air extraction port 14 of the rubber air extraction bag 2, and then the patient controls the main rod 4 to deliver the cupping jar to the back and other parts of the body that are usually difficult to reach. After the cupping jar is attached to the skin, the pressing rod 6 near the gripping handle 5 is made to close and rotate, and then the linkage rod 7 is pulled to transform the four-bar linkage into a flattened structure, and the rubber air extraction bag 2 clamped in the four-bar linkage frame is squeezed by the flattened four-bar linkage, thereby realizing the air extraction action. If one air extraction is not enough to complete the adsorption of the cupping jar, then the pressing rod 6 is released again, and the pressing rod 6 and the four-bar linkage are reset by the elasticity of the rubber air extraction bag 2 itself, or a torsion spring is set at the rotating shaft of the pressing rod 6, and the pressing rod 6 is gripped again to extract air until the cupping jar completes adsorption. After the adsorption is completed, the main rod 4 can be twisted circumferentially so that the rubber air extraction bag 2 can be broken off from the interface of the cupping jar. In order to firmly clamp the rubber air-pumping bag 2, it is best not to release the pressure rod 6 after the last air-pumping, so that the four-bar linkage always clamps the rubber air-pumping bag 2.
[0026] The device is provided with a main rod 4, thereby extending the user's arm, so that the cupping jar can be delivered to an area that is usually out of reach. And by providing a pressure rod 6 and a linked four-bar linkage, the user does not need to cooperate with both hands, and can complete the air-pumping action of the rubber air-pumping bag 2 by holding it tightly with one hand, which is simple and quick to operate. Moreover, when the four-bar linkage forming a parallelogram structure is in a flattening motion, the connecting rods on each opposite side can always maintain a parallel posture, so that when squeezing the rubber air-pumping bag 2, the rubber air-pumping bag 2 will not be tilted or skewed due to the non-parallel pushing of the bag body 11 by the rods on both sides, so that during the air-pumping and squeezing process, the cupping jar is guaranteed not to be misplaced or tilted and leaked, and the plugging of the cupping jar and the rubber air-pumping bag 2 is always maintained in a stable and leak-proof reliable state.
[0027] Based on the above implementation, in a preferred implementation, Figure 1 As shown, the cross section of the capsule 11 is circular and abuts against each connecting rod of the four-bar linkage. In this way, the capsule 11 is stuck in the four-bar linkage, and under the limitation of the four connecting rods in different directions, the axis of the capsule 11 is actually always located at the intersection of the diagonal lines of the parallelogram, ensuring that the cupping jar is accurately positioned. If the capsule 11 is only clamped by two side edges, the capsule 11 lacks limitation in the length direction of the clamping rod, and when the user delivers the cupping jar to the treatment site, it is not easy to accurately fix the cupping jar on the skin of the area to be treated.
[0028] Based on the above implementation, in a preferred implementation, Figure 1 and 2 As shown, a pressure plate 3 for increasing the contact area is provided at the contact point between each link of the four-bar linkage and the capsule 11. Because the rod is thin, long-term compression and friction with the capsule 11 will cause greater wear on the rubber material, so the pressure plate 3 for increasing the contact area can reduce the wear. And the pressure plate 3 can more easily abut against the flat section of the capsule 11, while if it is a rod, it is easier to press and contact the arc section of the capsule 11, which is not conducive to the axial positioning of the capsule 11.
[0029] Based on the above implementation, in a preferred implementation, Figure 2 and 3 As shown, a slot 13 is provided on the capsule 11, and the pressure plate 3 is embedded in the slot 13. This arrangement mainly provides a better axial positioning capability for the capsule 11. The four-bar linkage has a better radial positioning capability for the capsule 11, but the axial positioning of the capsule 11 can only be achieved through friction. After the slot 13 is provided, the pressure plate 3 is embedded in the slot 13, so that a step structure abuts and limits on the axis of the capsule 11, ensuring the stable positioning of the capsule 11 in the axial direction, especially helping to pull out the rubber air pumping bag 2 after pumping.
[0030] Based on the above implementation, in a preferred implementation, Figure 2 and 3As shown, the slot 13 is an annular groove arranged around the capsule 11, and each pressing plate 3 has the same height, and the top and bottom ends of each pressing plate 3 are inserted into the slot 13. If a single-body slot 13 completely corresponding to each pressing plate 3 is arranged on the capsule 11, on the one hand, a higher mold precision is required, and on the other hand, the slot 13 is difficult to always keep accurate engagement with the pressing plate 3 due to the asynchronism of the four-bar linkage and the capsule 11 during the deformation process. Therefore, the slot 13 is set as an annular groove, which not only reduces the mold precision requirements for the capsule 11, but also ensures the tight limitation of the top and bottom sides between the pressing plate 3 and the slot 13 during the deformation process of the four-bar linkage and the capsule 11, and can also produce a left-right direction shift, so as to coordinate and adapt to the different deformation rates of the two.
[0031] Based on the above implementation, in a preferred implementation, Figure 2 and 3 As shown, two flanges 12 are arranged in parallel on the capsule 11; the two flanges 12 protrude from the outer surface of the capsule 11, thereby forming a slot 13. Excavating the slot 13 on the capsule 11 will cause a large difference in the wall thickness of the capsule 11, thereby affecting its performance such as resilience. However, the provision of two flanges 12 is equivalent to raising the slot 13, thereby avoiding the damage of the slot 13 to the wall thickness of the capsule 11.
[0032] Based on the above implementation, in a preferred implementation, Figure 1 As shown, the four-bar linkage, the pressure rod 6 and the linkage rod 7 are all located on the same side of the main rod 4. This arrangement can avoid the linkage rod 7 from crossing the main rod 4 for connection, shorten the length of the linkage rod 7, simplify the overall structure, and avoid the appearance of more complex structures such as holes or bends.
[0033] Based on the above implementation, in a preferred implementation, Figure 1 and 2 As shown, the rubber air bag 2 is detachably connected to the four-bar linkage, and the rubber air bag 2 can be connected to the four-bar linkage after being reversed. Although the rubber deformable bag 11 and the clamping structure between it and the connecting rod usually mean that the rubber air bag 2 is detachably connected to the four-bar linkage, this point is particularly emphasized here because the structure of the handle 5 and the pressure rod 6 must be located at the palm and the pressure rod 6 at the fingertips when in use, which makes a difference for left-handed and right-handed people. Figure 1For example, if the air suction port 14 of the rubber air suction bag 2 is facing the reader, then this type of cupping device is convenient for right-handed people to use, and the fire cup can be easily close to the back skin under the correct grip. However, this is very inconvenient for left-handed people, because the fire cup will be facing away from the skin when the left hand is gripped. Therefore, the rubber air suction bag 2 can be removed and then installed in reverse direction to solve this problem.
[0034] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
