Description

Technical Field

[0001] The invention relates to the field of limb lymphedema treatment, and in particular to a pressure treatment bandaging auxiliary device for limb lymphedema. Background Art

[0002] Lymphedema is caused by obstruction of lymphatic vessels or incomplete development of lymphatic vessels, which leads to obstruction of lymphatic drainage and retention of lymph in the interstitial space, resulting in local tissue swelling. The subsequent hypoxia can lead to chronic inflammation and tissue fibrosis. There are extensive capillary lymphatic vessels in the skin, and patients with lymphedema are prone to repeated skin infections due to the accumulation of antigens in the surrounding tissues.

[0003] Compression therapy can be used for patients with lymphedema. An elastic bandage is used to wrap around the affected limb in a spiral shape to compress the affected limb, control the circumference of the affected limb, and rely on the massage effect during exercise or use to produce a therapeutic effect.

[0004] When wrapping an affected limb with an elastic bandage, it is necessary to wrap from the end of the limb to the proximal end and gradually reduce the wrapping pressure of each circle to guide the return of lymph fluid. Currently, wrapping is usually done manually, but it is difficult to control the pressure of each wrapping during manual wrapping, and it is even more difficult to control the pressure change trend of each circle of bandage. In view of this, it is urgent to propose a pressure therapy bandage auxiliary device to facilitate the control of the pressure when the bandage is wrapped around the affected limb.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0034] like Figure 1-4 As shown, the pressure treatment bandaging auxiliary device for limb lymphedema provided in this embodiment includes a bottom frame 1, a movable seat 2, a pressure measuring component 3 and a driving component 4.

[0035] See also Figure 1 A threaded rod 11 is axially rotatably connected inside the frame body of the bottom frame 1, and the two ends of the threaded rod 11 are rotatably connected to the inner walls of the two ends of the bottom frame 1. In order to facilitate the rotation of the threaded rod 11, in one embodiment, one end of the threaded rod 11 passes through the outside of the bottom frame 1 and is provided with a rotating handle 14. Preferably, the rotating handle 14 can also be replaced by a motor. Guide rods 12 are respectively provided on both sides of the threaded rod 11 inside the bottom frame 1. Both guide rods 12 are parallel to the threaded rod 11. A rack 121 is provided on one of the guide rods 12, and the rack 121 is arranged along the axial direction of the guide rod 12. In order to facilitate the placement of the bottom frame 1, preferably, a base is also provided at the bottom of the bottom frame 1.

[0036] See also Figure 1-Figure 4The bottom of the moving seat 2 is threadedly connected to the threaded rod 11 and is slidably connected to the two guide rods 12 respectively, wherein the threaded rod 11 is used to drive the moving seat 2 to move along its axial direction, and the two guide rods 12 are used to provide a moving guide for the moving seat 2. A through hole 21 is provided on the moving seat 2 for the patient's affected limb to pass through, and a winding ring 22 is axially connected to the through hole 21. Specifically, the interior of the moving seat 2 has a cavity 24, and the outer ring of the winding ring 22 is located in the cavity 24 and is provided with a bearing 221. The outer ring of the bearing 221 is fixedly connected to the cavity 24 through a bracket 222, and the inner ring of the bearing 221 is fixedly connected to the winding ring 22. A bandage box 23 is provided on the inner wall of the winding ring 22. The rotation of the winding ring 22 can make the bandage in the bandage box 23 wrap around the affected limb, and the bandage can be spirally wrapped around the affected limb in cooperation with the threaded rod 11 to drive the moving seat 2 to move. Furthermore, a helical gear ring 223 is provided on one side of the outer ring of the winding ring 22.

[0037] Since a certain pressure needs to be applied when the bandage is wrapped around the affected limb, further, a coil spring and a bandage are provided in the bandage box 23, one end of the bandage is connected to the coil spring, and the other end of the bandage is wrapped around the coil spring and moves out of the bandage box 23. The specific installation method of the coil spring is common knowledge and will not be described in detail here. When the winding ring 22 rotates to continuously draw the bandage out of the bandage box 23 and wrap around the affected limb, the coil spring applies a winding and converging force to the bandage, so that the bandage can be tightened and close to the affected limb to prevent the bandage from loosening.

[0038] Please continue reading Figure 1-Figure 4 The pressure measuring assembly 3 includes a support 31, a pressure measuring piece 32 and a pressure display 33. The support 31 is installed on one side of the movable seat 2, and the pressure measuring piece 32 is installed on the support 31. One end of the pressure measuring piece 32 extends into the inner circle of the winding ring 22 and a pressure sensor is arranged on the end. The pressure display 33 is installed on one side of the movable seat 2 and is electrically connected to the pressure sensor. Among them, the pressure sensor can be a patch pressure sensor or a film pressure sensor, which is conducive to making the pressure measuring piece 32 thinner. When the bandage is wrapped around the affected limb, it can be wrapped together with the pressure measuring piece 32. The pressure sensor on the pressure measuring piece 32 can display the pressure of the currently wrapped affected limb in real time on the pressure display 33, which is conducive to allowing medical staff to view the pressure condition of the affected limb in real time and adjust it according to the display data of the pressure display 33.

[0039] Since when the bandage is wrapped around the affected limb, it is necessary to wrap from the end of the limb to the proximal end and gradually reduce the wrapping pressure of each circle to guide the lymphatic fluid backflow, it is necessary to individually detect each circle of the bandage wrapped around the affected limb to prevent the affected limb from being unevenly pressurized and causing poor lymphatic fluid backflow. In order to prevent the first circle of bandage from affecting the measurement of the next circle of bandage, in one embodiment, a fixed plate 34 is installed on the support 31, and a sliding block 35 is slidably connected to the side of the fixed plate 34 close to the wrapping ring 22 on the support 31, and the pressure measuring plate 32 is installed on the sliding block 35. A first elastic member 36 is connected between the sliding block 35 and the fixed plate 34, and the first elastic member 36 can provide an elastic force to push the sliding block 35 toward the wrapping ring 22, so that the pressure sensor is located in the inner circle of the wrapping ring 22. The pressure is tested after each bandage is wrapped around the affected limb. After the test and adjustment are completed, the sliding block 35 can be moved to completely move the pressure measuring piece 32 out of the wrapped bandage. The pressure measuring piece 32 will return to its initial position under the elastic force of the first elastic member 36 and be located outside the first circle of bandage, waiting for the pressure of the next circle of bandage to be tested.

[0040] like Figure 4 As shown, preferably, the side of the sliding block 35 facing the winding ring 22 is a conical surface, and the winding ring 22 is provided with a support column 224 extending toward the sliding block 35, and the end of the support column 224 can abut against the conical surface of the sliding block 35. In specific use, each time the winding ring 22 rotates one circle, the support column 224 will push the sliding block 35 once, so that the pressure measuring plate 32 is completely moved out of the wound bandage, and then after the bandage is wrapped around the affected limb once, the position of the pressure sensor can be reset through the support column 224, so as to perform the pressure detection of the next bandage winding, which is conducive to reducing the operation steps of medical staff.

[0041] Preferably, the pressure measuring piece 32 has an arc on one side of the inner circle of the winding ring 22 close to the skin of the affected limb, so that the pressure measuring piece 32 does not scratch the wrapped bandage when returning to the initial position under the action of the first elastic member 36.

[0042] In order to make the pressure measuring piece 32 close to the skin surface of the affected limb, a more accurate pressure detection result can be obtained. Figure 4 As shown, in one embodiment, a telescopic groove 351 is provided on the sliding block 35, and a telescopic column 352 is slidably connected in the telescopic groove 351. A second elastic member 353 is connected between the telescopic column 352 and the bottom of the telescopic groove 351. The second elastic member 353 can provide an elastic force to push the telescopic column 352 out of the telescopic groove 351, and the pressure measuring plate 32 is installed on the outer end of the telescopic column 352.

[0043] It should be noted that both the first elastic member 36 and the second elastic member 353 may be springs.

[0044] See also Figure 3 The driving assembly 4 is used to drive the winding ring 22 to rotate. Specifically, the driving assembly 4 is installed in the cavity 24, and the driving assembly 4 includes an active rod 41 and a driven rod 42. The active rod 41 and the driven rod 42 are respectively rotatably connected in the cavity 24, and the active rod 41 and the driven rod 42 are connected by a belt 43. The active rod 41 is provided with a driving gear 44, one side of the driving gear 44 passes through the cavity 24 and is connected to the rack 121, and the driven rod 42 is provided with a bevel gear 45, which is connected to the bevel gear ring 223. During specific use, the threaded rod 11 rotates to drive the moving seat 2 to move. When the moving seat 2 moves, the driving gear 44 will rotate on the path of the rack 121, and then drive the driven rod 42 to rotate through the belt 43, and then drive the winding ring 22 to rotate through the bevel gear 45 and the bevel gear ring 223, so that the movement of the moving seat 2 and the rotation of the winding ring 22 can be achieved only by rotating the threaded rod 11, thereby realizing the spiral winding of the bandage on the affected limb.

[0045] like Figure 1 As shown, in one embodiment, support seats 13 are slidably connected to both sides of the movable seat 2 on the guide rod 12, and the support seats 13 are used to support the affected limb and provide a placement platform for the affected limb.

[0046] The pressure treatment bandaging auxiliary device for limb lymphedema provided by the present invention is used in practice. The patient first passes the affected limb through the through hole 21, rotates the threaded rod 11 to move the movable seat 2 to the end of the affected limb, and completes the preparation work; the medical staff takes out one end of the bandage in the bandage box 23 and positions it on the affected limb, and rotates the threaded rod 11 again to move the movable seat 2 toward the proximal end of the affected limb. When the movable seat 2 moves, the winding ring 22 is synchronously driven to rotate through the driving component 4, so that the bandage is spirally wound around the affected limb; after each circle of the bandage is wound, the pressure display 33, check the real-time pressure data measured by the pressure sensor on the pressure measuring piece 32, and adjust the pressure value by pulling the bandage in the bandage box 23 according to the principle that the pressure gradually decreases from the end of the affected limb to the proximal end. After the adjustment, continue to rotate the threaded rod 11, and the support column 224 will pass and push the sliding block 35 before the next circle is wrapped, so as to push the pressure measuring piece 32 out of the bandage. The pressure measuring assembly 3 returns to the initial position under the action of the first elastic member 36 and waits for the next measurement; then continue to cycle the above operations until the bandage wraps the affected limb completely.

[0047] The present invention utilizes the pressure measuring component 3 to accurately measure the real-time pressure value of each circle of bandage wrapped around the affected limb, which is helpful for helping medical staff to accurately control the pressure of each wrapping, precisely control the pressure change trend of each circle of bandage, and improve the treatment effect on the patient; the driving component 4 cooperates with the movement of the movable seat 2 to drive the winding ring 22 to rotate, so that the movement of the movable seat 2 and the rotation of the winding ring 22 can be achieved only by rotating the threaded rod 11, thereby realizing the spiral winding of the bandage around the affected limb, which can be started and stopped at any time, and the operation is quick and easy; at the same time, the rotation of the winding ring 22 is utilized to control the resetting of the pressure measuring component 3 through the support column 224, thereby reducing the workload of medical staff.
