Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The present invention provides an adjustable lymphedema auxiliary treatment device for breast cancer surgery, comprising a base 1, one end of the base 1 is fixedly connected to a motor 2, an output end of the motor 2 is connected to a reciprocating screw 3, a slider 4 is arranged on the outside of the reciprocating screw 3, a support plate 5 is connected to the upper end of the slider 4, an air bag 6 is arranged inside the support plate 5, a connecting pipe 7 is connected to the outside of the air bag 6, an end of the connecting pipe 7 away from the air bag 6 is connected to an air pressure chamber 8, a push rod 9 is arranged inside the air pressure chamber 8, a drug guide tube 10 is fixedly connected to the upper end of the slider 4, and the drug guide tube 10 is fixedly connected to the upper end of the slider 4. 0 is provided with a ball 11 at one end, a groove 12 is provided on the outer side of the ball 11, a rack 13 is connected to one side of the slider 4, a gear 14 is provided inside the base 1, a threaded shaft 15 is connected to the axis of the gear 14, a threaded rod 16 is provided inside the threaded shaft 15, a movable plate 17 is connected to one end of the threaded rod 16, a medicine storage tank 20 is provided on the outer side of the movable plate 17, a spring rod 21 is provided inside the rack 13, a movable block 22 is fixedly connected to one end of the spring rod 21, and a limited position block 23 is fixedly connected to one side of the movable block 22.

[0032] In an optional embodiment, a hollow groove is opened at the center of the upper end of the base 1, and the reciprocating screw 3 is located inside the hollow groove. The reciprocating screw 3 passes through the base 1 and extends to the outer end to be connected with the motor 2. Two groups of sliders 4 are arranged at both ends of the outer side of the reciprocating screw 3, and the sliders 4 are connected to the ball nut pair of the reciprocating screw 3. When in use, the reciprocating screw 3 is driven to rotate by the motor 2, so that when the reciprocating screw 3 rotates, it will drive the two groups of sliders 4 to move back and forth synchronously toward the center.

[0033] In an optional embodiment, the upper ends of the two groups of sliders 4 are connected to a support plate 5, and a guide block is provided at the lower end of the support plate 5. The slider 4 is connected to the guide block. When in use, the patient places his arm on the upper end of the support plate 5. As described above, when the two groups of sliders 4 move, they will slide along the guide block at the lower end of the support plate 5, so that the guide block provides a guiding function for the slider 4, and at the same time detects whether the movement of the slider 4 is offset during use.

[0034] In an optional embodiment, the airbag 6 is fixedly connected to the inside of the support plate 5, and the air pressure chamber 8 is fixedly connected to the inside of the slider 4 away from the end of the motor 2. There are two groups of them. One end of the air pressure chamber 8 is connected to the connecting tube 7, and the end of the connecting tube 7 away from the air pressure chamber 8 passes through the support plate 5 and is connected to the airbag 6. The push rod 9 is located inside the air pressure chamber 8, and the outer diameter of the push rod 9 matches the inner diameter of the air pressure chamber 8. As mentioned above, when the two groups of sliders 4 move toward the center, one group of sliders 4 will contact the push rod 9, thereby squeezing the push rod 9 to shrink into the air pressure chamber 8, so that the air pressure chamber 8 squeezes the air pressure inside the air pressure chamber 8 and transmits it to the rear end, thereby entering the airbag 6 through the connecting tube 7, causing the airbag 6 to expand and squeeze the patient's arm, thereby forming a uniform and orderly squeezing of the limbs from the distal end to the proximal end, simulating professional massage techniques, promoting the flow of blood and lymphatic tissue and improving microcirculation, accelerating the reflux of limb tissue fluid, effectively reducing edema, and preventing muscle atrophy and fibrosis.

[0035] In an optional embodiment, the drug guiding tube 10 is fixedly connected to the upper end of the slider 4, and there are two groups of drug guiding tubes 10. The drug guiding tube 10 extends through the slider 4 to the lower end. The lower end of the drug guiding tube 10 is movably connected with a ball 11. The ball 11 is set at the lower end of the two groups of drug guiding tubes 10. The groove 12 is opened on the outside of the ball 11. When the two groups of sliders 4 move back and forth, the drug guiding tube 10 will be driven to move synchronously. When the drug guiding tube 10 moves, the ball 11 at the lower end will contact the patient's arm, so that the ball 11 will rotate due to friction with the surface of the arm during movement. When the ball 11 rotates, part of the medicine will be brought out through the groove 12 on the surface, so that the patient can be medicated during massage, thereby forming a synergistic effect and improving the treatment effect.

[0036] In an optional embodiment, the rack 13 is fixedly connected to the slider 4 on the side close to the motor 2, and the gear 14 is movably connected inside the base 1. The gear 14 and the rack 13 are in the same plane, and the groove 12 is meshed with the gear 14. The threaded shaft 15 passes through the center of the gear 14, and the threaded shaft 15 is fixedly connected to the gear 14. When the slider 4 moves back and forth, it will drive the rack 13 to move synchronously, so that the rack 13 will drive the gear 14 to rotate when it moves. Because the gear 14 is fixedly connected to the threaded shaft 15, it will drive the threaded shaft 15 to rotate synchronously when the gear 14 rotates.

[0037] In an optional embodiment, a threaded rod 16 is disposed inside the threaded shaft 15, and the threaded rod 16 is threadedly connected to the threaded shaft 15. The threaded rod 16 extends to the upper end into the medicine storage tank 20, and one end of the threaded rod 16 extending into the medicine storage tank 20 is fixedly connected to a movable plate 17, and the outer diameter of the movable plate 17 matches the inner diameter of the medicine storage tank 20. As described above, when the threaded shaft 15 rotates, the threaded rod 16 will be driven to rise synchronously, and when the threaded rod 16 rises, the movable plate 17 will be driven to rise synchronously, thereby squeezing the medicine inside the medicine storage tank 20 to gradually rise. When squeezing the medicine inside the medicine storage tank 20, the movable plate 17 will squeeze the medicine into the drug delivery tube at the upper end of the medicine storage tank 20, and at the same time, the drug delivery tube is connected to the drug guide tube 10, thereby preventing the medicine from being cut off when applying the medicine.

[0038] In an optional embodiment, two groups of protrusions 18 are fixedly connected on both sides of the movable plate 17, and two groups of slide grooves 19 are opened on the inner wall of the medicine storage tank 20. The size of the slide groove 19 matches the size of the protrusion 18. When the threaded rod 16 rises, it moves and rises inside the slide groove 19 through the protrusions 18 on both sides, thereby preventing the threaded rod 16 from deflecting when it rises.

[0039] In an optional embodiment, the medicine storage tank 20 is fixedly connected to the upper end of the base 1. The medicine storage tank 20 is made of transparent material and has a scale on the outside. Medical staff can add an appropriate amount of medicine through the scale. At the same time, the scale matches the movement time of the slider 4, so as to adjust the usage time according to patients with different conditions.

[0040] In an optional embodiment, one end of the spring rod 21 is fixedly connected to the inside of the rack 13, and the other end thereof is connected to the movable block 22. The spring rod 21 is arranged on both sides of the movable block 22, and there are two groups of spring rods 21. The limit block 23 is located on one side of the movable block 22, and the limit block 23 is fixedly connected to the rack 13, and there are multiple groups of limit blocks 23. When the slider 4 drives the rack 13 to move and contact the gear 14, the movable block 22 inside the rack 13 cannot be flipped due to the limit of the limit block 23, so that the movable block 22 drives the gear 14 to rotate. When the slider 4 is reset, because the movable block 22 is movably connected through the spring rod 21, it will flip to one side when the movable block 22 contacts the gear 14, so that it cannot drive the gear 14 to rotate when the slider 4 is reset.

[0041] Working principle: when in use, the patient places his arm on the upper end of the support plate 5, and then drives the reciprocating screw 3 to rotate through the motor 2, so that when the reciprocating screw 3 rotates, it will drive the two groups of sliders 4 to move back and forth synchronously toward the center. When the two groups of sliders 4 move toward the center, one group of sliders 4 will contact the push rod 9, thereby squeezing the push rod 9 to contract inside the air pressure chamber 8, so that the air pressure chamber 8 squeezes the air pressure inside the air pressure chamber 8 and transmits it to the rear end, thereby entering the air bag 6 through the connecting tube 7, so that the air bag 6 expands to squeeze the patient's arm;

[0042] When the two sets of sliders 4 move back and forth, the drug guiding tube 10 will be driven to move synchronously. When the drug guiding tube 10 moves, the ball 11 at the lower end will contact the patient's arm, so that the ball 11 will rotate by friction with the surface of the arm during movement. When the ball 11 rotates, it will take out part of the medicine through the groove 12 on the surface, so as to apply medicine to the patient during massage.

[0043] When the slider 4 moves back and forth, it will drive the rack 13 to move synchronously, so that the rack 13 will drive the gear 14 to rotate when it moves, and when the gear 14 rotates, it will drive the threaded shaft 15 to rotate synchronously, and when the threaded shaft 15 rotates, it will drive the threaded rod 16 to rise synchronously, and when the threaded rod 16 rises, it will drive the movable plate 17 to rise synchronously, so that the medicine inside the medicine storage tank 20 will gradually rise, and when the threaded rod 16 squeezes the medicine inside the medicine storage tank 20, it will squeeze the medicine into the drug delivery tube at the upper end of the medicine storage tank 20.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
