By arranging limb fixing structures, when limbs are fixed, rubber strips are extruded to enable arc-shaped frames to drive limb fixing rings to turn over towards the inner side, meanwhile, the limb fixing rings push sliding rods to slide towards the outer side to enable compression springs to extend, and then the distance between the middles of the two limb fixing rings can be adjusted in a self-adaptive mode; after the limb fixing rings are turned over, the magnetic attraction blocks are automatically attracted, then the arm can be rapidly fixed, meanwhile, before the arm is fixed, the hand wheel is rotated to drive the two-way threaded rod to rotate, the relative positions of the limb fixing rings on the two sides can be adjusted, and therefore the suture removing position or a wound can be effectively prevented from being blocked; the limb fixing structure is integrally arranged in the positioning box and the protective box cover and is in a closed state, and the interiors of the positioning box and the protective box cover are in a sterile environment, so that infection of external bacteria to a wound can be effectively avoided.

Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a limb positioning device. Background Art

[0002] Limb positioning for dressing changes refers to the process of immobilizing a patient's limb using specialized medical devices during dressing changes or suture removal procedures in an outpatient operating room. The goal is to ensure the limb is in a stable position, fully exposing the operative area, while preventing the patient from moving due to pain or discomfort, which could compromise the procedure.

[0003] For example, a limb positioning device for dressing change and suture removal in an outpatient operating room disclosed in Chinese patent publication number (CN221490545U) records: "It includes a fixing ring and a threaded rod, a threaded rod is provided inside the fixing ring, the threaded rod and the fixing ring are slidably connected, a threaded sleeve is provided on the top of the fixing ring, the threaded sleeve and the threaded rod are threadedly connected, the threaded sleeve and the fixing ring are slidably connected, an adjusting rod is provided on one side of the threaded sleeve, the adjusting rod and the threaded sleeve are fixedly connected, four adjusting rods are provided, a limiting groove is embedded in the surface of the threaded rod, the inner wall of the fixing ring is fixedly connected to a limiting block, the limiting block is slidably connected to the limiting groove, a positioning frame is provided on the top of the threaded rod, and the positioning frame is fixedly connected to the threaded rod. The height adjustment of the device is achieved by means of the fixing ring, threaded rod, threaded sleeve, adjusting rod, limiting groove and limiting block, so that it can be applied to more complex terrains, thereby improving the use value of the device."

[0004] In summary, the device still has the following technical problems: the above-mentioned device fixes the limbs by setting up an extrusion fixing mechanism, but the treatment of the patient's limb wounds must be carried out in a sterile environment, otherwise it is very likely to cause wound infection. At the same time, since the users, arm sizes and wound positions are different, the above-mentioned device will block part of the arm when treating the wound or removing the stitches. For this reason, it is necessary to propose a limb positioning device to provide a new technical solution to solve the technical problems mentioned in the above patents. Summary of the Invention

[0005] Based on this, it is necessary to provide a limb positioning device to address the above technical problems. By setting a limb fixing structure, when the limb is fixed, the arc frame squeezes the rubber strip to drive the limb fixing ring to flip inward. At the same time, the limb fixing ring pushes the slide bar to slide outward to extend the compression spring, thereby enabling the middle distance between the two limb fixing rings to be adaptively adjusted. After the limb fixing ring is flipped, the magnetic block is automatically adsorbed, thereby achieving rapid fixation of the arm.

[0006] At the same time, before the arm is fixed, the relative positions of the limb fixation rings on both sides can be adjusted by rotating the handwheel to drive the bidirectional threaded rod to rotate, which can effectively avoid obstruction of the suture removal site or the wound. Since the limb fixation structure is arranged as a whole inside the positioning box and the protective box cover in a closed state, and the interior of the positioning box and the protective box cover is in a sterile environment, it can effectively avoid external bacteria from infecting the wound.

[0035] As described in the background, the above device realizes the fixation of the limb by setting the extrusion fixing mechanism, but the patient's limb wound treatment needs to be carried out in a sterile environment, otherwise it is extremely likely to cause infection of the wound, and at the same time, due to the different sizes of the user and the arm and the position of the wound, the above device will block part of the position of the arm when treating the wound or removing the stitches.

[0036] In order to solve this technical problem, the present application provides a limb positioning device.

[0037] Specifically, please refer to Figures 1-3 , the limb positioning device specifically comprises a positioning box 1, the upper end of the positioning box 1 is hingedly provided with a protective box cover 2, the surface of the protective box cover 2 is provided with a dressing change structure 3, the inside of the positioning box 1 is provided with a limb fixing structure 4, and the two ends of the positioning box 1 and the protective box cover 2 are respectively provided with an end closing structure 5;

[0038] The limb fixing structure 4 includes a baffle 13 symmetrically fixedly arranged inside the positioning box 1 . A guide frame 14 is fixedly connected to the inside of the positioning box 1 . A rectangular slot 15 is formed inside the guide frame 14 .

[0039] The limb positioning device provided by the present invention is provided with a limb fixing structure 4. When the limb is fixed, the arc frame 26 squeezes the rubber strip 32 to drive the limb fixing ring 30 to flip inward. At the same time, the limb fixing ring 30 pushes the slide bar 27 to slide outward to extend the compression spring 29, thereby enabling the middle distance between the two limb fixing rings 30 to be adaptively adjusted. After the limb fixing ring 30 is flipped, the magnetic block 31 is automatically attracted, thereby achieving rapid fixation of the arm.

[0040] At the same time, before the arm is fixed, the relative positions of the limb fixing rings 30 on both sides can be adjusted by rotating the hand wheel 17 to drive the bidirectional threaded rod 16 to rotate, which can effectively avoid obstruction of the suture removal site or the wound. Since the limb fixing structure 4 is arranged as a whole inside the positioning box 1 and the protective box cover 2 in a closed state, and the interior of the positioning box 1 and the protective box cover 2 is in a sterile environment, it can effectively avoid external bacteria from infecting the wound.

[0042] Example 1:

[0043] Please refer to Figures 2-6 A limb positioning device includes a positioning box 1, a protective box cover 2 is hingedly provided at the upper end of the positioning box 1, a dressing changing structure 3 is provided on the surface of the protective box cover 2, a limb fixing structure 4 is provided inside the positioning box 1, and end closing structures 5 are provided at both ends of the positioning box 1 and the protective box cover 2;

[0044] The limb fixing structure 4 includes a baffle 13 symmetrically fixedly arranged inside the positioning box 1 . A guide frame 14 is fixedly connected to the inside of the positioning box 1 . A rectangular slot 15 is formed inside the guide frame 14 .

[0045] Specifically, a bidirectional threaded rod 16 is rotatably provided inside the protective box cover 2 , both ends of the bidirectional threaded rod 16 extend to the outside of the protective box cover 2 , and both ends of the bidirectional threaded rod 16 are fixedly connected to a hand wheel 17 .

[0046] Specifically, the surface of the bidirectional threaded rod 16 is threadedly connected to a connecting seat 18, the top surface of the connecting seat 18 is fixedly connected to a guide block 19, the guide block 19 is slidably set on the inner wall of the rectangular groove 15, the top surface of the guide block 19 is fixedly connected to a guide rod 20, and protrusions are set on both sides of the top of the guide rod 20.

[0047] Specifically, a lifting sleeve 21 is sleeved on the surface of the guide rod 20, and avoidance grooves 23 are opened on both sides of the lifting sleeve 21. The protrusion at the top of the guide rod 20 is slidably set on the inner wall of the avoidance groove 23, and a return spring 22 is set inside the lifting sleeve 21.

[0048] Specifically, the top of the lifting sleeve 21 is fixedly connected to the top positioning frame 24, and the two ends of the top positioning frame 24 are respectively fixedly provided with an axis rod 25. The surface of the axis rod 25 is rotatably provided with an arc frame 26, and the end of the arc frame 26 away from the top positioning frame 24 is slidably provided with a slide rod 27. One end of the slide rod 27 is fixedly connected to the limiting block 28, and the end of the slide rod 27 away from the limiting block 28 is fixedly connected to the limb fixing ring 30. The surface of the slide rod 27 is sleeved with a compression spring 29, and the two ends of the compression spring 29 are respectively fixedly connected to the arc frame 26 and the limiting block 28. The end of the limb fixing ring 30 is fixedly connected with a magnetic block 31, and a plurality of rubber strips 32 are provided inside the limb fixing ring 30.

[0049] According to the above structural design, when the device is used, the protective box cover (2) and the positioning box (1) are first opened. After completion, the position of the wound suture removal is penetrated, and the bidirectional threaded rod (16) is driven to rotate by turning the hand wheel (17) so that the connecting seat (18) and the guide block (19) slide on the inner wall of the rectangular groove (15) to adjust the position of the limb fixing ring (30). After completion, the arm is placed inside the limb fixing ring (30) and squeezed. After the limb fixing ring (30) is squeezed by hand, it is turned inward on the surface of the shaft (25) through the arc frame (26). The limb fixing ring (30) rotates, and at the same time, the sliding rod (27) is pushed to extend outward at the end of the arc frame (26) to adjust the space inside the limb fixing ring (30). The sliding rod (27) moves and stretches the compression spring (29) outward. The compression spring (29) pulls the sliding rod (27) to apply a reaction force to the limb fixing ring (30). At this time, the limb fixing ring (30) can squeeze the arm. When the limb fixing ring (30) turns ninety degrees, the magnetic blocks (31) at the rear end attract each other, thereby achieving locking of the arm.

[0050] When the limb is placed, pressure is applied to the lifting sleeve (21) through the top positioning frame (24). The lifting sleeve (21) is squeezed on the surface of the guide rod (20) and slides downward. When the lifting sleeve (21) slides, the protrusions on both sides slide on the inner wall of the avoidance groove (23). When the lifting sleeve (21) slides, the reset spring (22) is compressed, thereby locking the arm. When the arm is removed, a slight force is applied to lift it upward to separate the two magnetic blocks (31). After the magnetic blocks (31) are separated, the limb fixing ring (30) is turned outward, and thus quick disassembly can be completed.

[0051] Example 2:

[0052] The limb positioning device provided in Example 1 is further optimized, specifically, as follows Figure 2 、 Figure 3 、 Figure 7 and Figure 8 As shown, the two ends of the positioning box 1 and the protective box cover 2 are respectively fixedly connected with a protective ring 33, the inside of the protective ring 33 is fixedly connected to the surface of the positioning box 1 with a tripod 34, the inner wall of the tripod 34 is slidably provided with a light rod 35, one end of the light rod 35 is fixedly provided with an extrusion block 36, the surface of the light rod 35 is sleeved with a positioning spring 37, the two ends of the positioning spring 37 are respectively fixedly connected with the tripod 34 and the extrusion block 36, and the surface of the extrusion block 36 is provided with an elastic rubber ring 38.

[0053] Specifically, the dressing changing structure 3 includes a handle 6 symmetrically arranged on the top surface of the protective box cover 2 , an ultraviolet sterilization lamp 10 and an illumination lamp 11 are respectively arranged inside the protective box cover 2 , and a perspective window 12 is arranged in the middle of the protective box cover 2 .

[0054] Specifically, a conical tube 7 is symmetrically fixedly provided on the front of the protective box cover 2 , and an installation cylinder 8 is fixedly connected to one end of the conical tube 7 away from the protective box cover 2 . A rubber sealing ring 9 is provided on the inner wall of the installation cylinder 8 .

[0055] Through the above structural design, when the arm is placed inside the limb fixing structure 4, the elastic rubber ring 38 is squeezed, and the elastic rubber ring 38 is squeezed and adheres to the skin. At the same time, the elastic rubber ring 38 pushes the squeezing block 36 to drive the polished rod 35 to slide inside the tripod 34. The shaft 25 slides and compresses the positioning spring 37. After completion, the upper protective box cover 2 is flipped down and buckled with the positioning box 1. When the protective box cover 2 is flipped down, the elastic rubber ring 38 contacts the skin. The elastic rubber ring 38 is subjected to the reaction force to push the squeezing block 36 to make the polished rod 35 slide inside the tripod 34, squeezing and contracting the positioning spring 37, so that the positioning box 1 and the protective box cover 2 can be closed at both ends.

[0056] When treating a wound or removing stitches, turn on the ultraviolet sterilization lamp 10 and the lighting lamp 11, and the medical staff's hands are inserted into the interior of the protective box cover 2 through the installation tube 8 and the tapered tube 7 to treat the limbs inside the protective box cover 2. When the medical staff's hands enter the interior of the protective box cover 2, they squeeze the rubber sealing ring 9, and the rubber sealing ring 9 is always in close contact with the medical staff's arms, which can effectively prevent the entry of bacteria.
