Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a bloodletting and cupping device. Background Art

[0002] Blood-pricking and cupping is a traditional Chinese medical treatment method that combines acupuncture and cupping. It mainly achieves the purpose of treating diseases by acupuncture at specific acupuncture points or parts, and using the negative pressure of cupping to suck out the blood stasis. During treatment, the treatment area is first disinfected, and then a sterile blood-pricking needle is used to prick the affected area. Then, the glass jar is quickly buckled at the puncture position using the flash fire method, and the blood stasis is sucked out using the negative pressure. It can be seen that the traditional blood-pricking and cupping method is difficult to operate, and it is not easy to control the negative pressure, which may cause local tissue damage. At present, some cupping devices have a needle-pricking mechanism installed in the tank body. After the tank body is turned upside down on the affected area, the affected area can be acupunctured by pressing the needle-pricking mechanism to achieve the purpose of bloodletting, which reduces the difficulty of operation, but the negative pressure of cupping is still difficult to control. Therefore, a new cupping device is urgently needed to further reduce the difficulty of operation. Utility Model Content

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] like Figures 1 to 3As shown, the pricking cupping device of this embodiment comprises a tank body 1, a push rod 2, a piston 6 and a pricking needle 7. The lower end of the tank body 1 is open, and the upper end is provided with a through hole 11 coaxial with the tank body 1, the push rod 2 passes through the through hole 11 at the upper end of the tank body 1, the push rod 2 can slide on the through hole 11, the piston 6 can be slidably arranged in the tank body 1 up and down, and the upper end of the piston 6 is connected to the lower end of the push rod 2, the pricking needle 7 is fixedly connected to the lower end of the piston 6, and the needle tip of the pricking needle 7 faces downward, so that when the piston 6 is pushed downward, the needle tip of the pricking needle 7 can be inserted into the acupuncture point.

[0022] Specifically, a cylindrical cavity is provided inside the tank body 1, and the piston 6 is also cylindrical, which can cooperate with the cylindrical cavity of the tank body 1, so that the piston 6 can slide inside the tank body 1, wherein the piston 6 includes an inner slider 61 and a rubber sleeve 62 sleeved outside the inner slider 61, and the puncture needle 7 is fixed on the inner slider 61 and passes through the rubber sleeve 62, and the rubber sleeve 62 cooperates with the inner cavity of the tank body 1 to increase the air tightness, so that the piston 6 can change the internal air pressure of the tank body 1 when sliding, so that the tank body 1 can be adsorbed on the affected area. In addition, in order to facilitate observation of the inner side of the tank body 1, the tank body 1 can be made of transparent materials, such as glass, transparent plastic and other materials.

[0023] In some embodiments, the pricking needle 7 may adopt a single needle head, which is connected to the middle part of the lower end of the piston 6. Specifically, the single needle head is connected to the inner sliding block 61 of the piston 6 as a whole, the inner sliding block 61 is made of metal material, and the tail end of the single needle head is fixedly welded to the inner sliding block 61. The needle body of the single needle head is relatively thin, so that it can be used for acupuncture of relatively small acupoints.

[0024] like Figure 4 As shown, in other embodiments, the pricking needle 7 is a triangular needle, and the tip of the triangular needle is in the shape of a triangular cone. In this way, the tip of the triangular needle is sharper, which has a stronger stimulation to the acupuncture points and is conducive to rapid blood stasis removal.

[0025] like Figure 5 As shown, in some other embodiments, the pricking needle 7 can also be a plum blossom needle, which includes a plurality of needles evenly distributed at the lower end of the piston 6. The plum blossom needle is suitable for use in larger areas, such as the back and legs.

[0026] The piston 6 and the push rod 2 are detachably connected, which makes it easy to select different pricking needles 7 according to treatment needs and connect the corresponding piston 6 to the push rod 2. Specifically, a threaded head 8 is provided at the upper end of the piston 6, and a screw hole 9 is provided at the lower end of the push rod 2. The threaded head 8 is connected to the screw hole 9. The piston 6 can be removed or installed by relatively rotating the piston 6 and the push rod 2.

[0027] In order to facilitate hand-held pushing of the push rod 2 , a push piece 3 is provided on the top of the push rod 2 , and the push piece 3 protrudes from the side of the push rod 2 , so as to facilitate the moving operation of the push rod 2 .

[0028] In order to prevent the piston 6 from resetting downward under the air pressure at the upper end of the tank body 1, a bayonet 5 can be provided at the top of the tank body 1, one end of the bayonet 5 is connected to the tank body 1 by a hinge, and a plurality of slots 4 are provided at intervals on the push rod 2, and the bayonet 5 can be rotated and inserted into the slots 4 to limit the sliding of the push rod 2, wherein the bayonet 5 can include two bayonet pins arranged at an angle, and the slots 4 are annular, and the bayonet pins 5 on both sides can be respectively inserted into the two sides of the slots 4 when fixed, thereby improving the stability of the fixation. By inserting the bayonet pins 5 into different slots 4, the height position of the piston 6 in the tank body 1 can be controlled later, thereby facilitating the control of the size of the adsorption pressure.

[0029] In use, first push the piston 6 down to the outside of the tank body 1, then replace the appropriate piston 6 according to the treatment needs, so as to replace different pricking needles 7, for example, the pricking needle 7 can be replaced with a single needle, a triangular needle or a plum blossom needle, then pull the push rod 2 upwards so that the needle tip of the pricking needle 7 is a certain distance away from the lower end opening of the tank body 1, and the tank body 1 is turned upside down on the affected part, then push the push rod 2 downwards so that the pricking needle 7 is pierced on the acupuncture point, and finally pull the push rod 2 upwards so that the piston 6 slides upwards, so that negative pressure is formed between the lower end of the piston 6 and the skin, so that the tank body 1 is adsorbed on the affected part, and the bayonet 5 is rotated so that the bayonet 5 is stuck in the slot 4, the push rod 2 is fixed, and it is kept for 5 to 10 minutes, and then the tank body 1 is removed. In this way, acupuncture and cupping can be combined into one step, thereby simplifying the cupping operation.
