Description

Technical Field

[0001] This invention specifically relates to a foot wound dressing bracket. Background Technology

[0002] When burns, cuts, or other injuries occur on the feet, the wounds need to be treated promptly. After treatment, the wounds should be bandaged to isolate them from the external environment, prevent infection from bacterial exposure, and effectively stop bleeding. However, manual bandaging is time-consuming and laborious, so specialized bandaging equipment can be used to assist.

[0003] For example, Chinese invention patent No. 202011499580.5 provides a quick bandage device for the lower leg. This device can fix the ankle of the injured person through an ankle clamping mechanism, so that the leg can be better bandaged. It can also quickly bandage the injured lower leg through a bandaging mechanism, thereby improving the efficiency of bandaging.

[0004] However, most existing bandaging devices can only bandage the patient's legs. Since there is a certain angle between the ankle joint and the lower leg, traditional foot bandaging brackets cannot adjust the wrapping angle of the bandage according to the angle of the ankle joint of different patients. This makes it inconvenient to bandage the entire foot and lower leg, thus reducing its applicability. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention proposes a foot wound bandaging bracket to solve the technical problem mentioned in the background art: traditional foot bandaging brackets are mostly unable to adjust the wrapping angle of the bandage according to the angle of different patients' ankle joints, thus making it inconvenient to bandage the foot and lower leg as a whole.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a foot wound dressing bracket, comprising:

[0007] A lifting base, wherein a leg support is provided on the lifting base;

[0008] A first guide rod is disposed at one end of the leg rest and is arranged at an angle. The first guide rod is connected to the leg rest through a telescopic assembly.

[0009] The second guide rod is connected to the first guide rod via a locking assembly, and the angle between the second guide rod and the first guide rod is adjusted by the locking assembly.

[0010] The mounting ring is slidably disposed on the first guide rod and the second guide rod along the trajectory formed by the cooperation of the first guide rod and the second guide rod; and

[0011] A bandaging mechanism, located within the mounting ring, is used to bandage the patient's foot.

[0012] Furthermore, the telescopic assembly includes a telescopic rod, one end of which is fixedly connected to the leg support, and the other end of which is fixedly connected to the first guide rod.

[0013] Furthermore, a positioning cylinder is provided on the first guide rod, and a positioning rod is provided at one end of the leg support, the positioning rod slidingly passing through the positioning cylinder along its axis.

[0014] Furthermore, the locking component includes:

[0015] A first gear plate is disposed at one end of the first guide rod, and a threaded cylinder is disposed on the first gear plate;

[0016] A second gear disc is disposed at one end of the second guide rod and slidably sleeved on the threaded cylinder, and the second gear disc meshes with the first gear disc; and

[0017] A threaded knob is inserted into and screwed into the threaded cylinder to limit the movement of the second gear disc.

[0018] Furthermore, the mounting ring has a through groove, and a guide wheel is provided in the through groove. Both the first guide rod and the second guide rod have guide grooves, and the guide wheel is engaged in the guide groove.

[0019] Furthermore, the bandaging mechanism includes:

[0020] A movable ring is rotatably disposed within the mounting ring along its axis;

[0021] A drive assembly, disposed within the mounting ring and connected to the movable ring, drives the movable ring to rotate within the mounting ring; and

[0022] A spool, rotatably mounted on the movable ring along its axis and connected to the movable ring via a mounting assembly, has bandages wound on it.

[0023] Furthermore, the driving component includes:

[0024] A drive motor is mounted on the mounting ring, and a drive gear is provided on the output shaft of the drive motor.

[0025] A gear ring is disposed on the movable ring, and the drive gear meshes with the gear ring;

[0026] A handle is disposed on the mounting ring, and the handle is provided with a control switch for controlling the start and stop of the drive motor; and

[0027] The grip is hinged to the mounting ring, and the control switch is triggered when the grip rotates along its hinge point with the mounting ring.

[0028] Furthermore, the installation components include:

[0029] The mounting housing is fixedly mounted on the movable ring, and a baffle is provided at one side opening of the mounting housing;

[0030] A crossbar slides through the mounting housing along its axis, with both ends exposed outside the mounting housing. A pressure plate is provided on the crossbar, and a pressing plate is provided at one end of the crossbar.

[0031] Two sets of mounting brackets are arranged opposite each other and are respectively fixedly mounted on the mounting shell and the crossbar. Each set of mounting brackets has a fixing post on its opposite side. Both ends of the drum are rotatably secured to the two sets of fixing posts.

[0032] The elastic element has two ends that abut against the baffle and the pressure plate, respectively.

[0033] Furthermore, the mounting housing is provided with a pressing component that contacts the bandage to tighten the bandage during bandaging.

[0034] Furthermore, the pressing assembly includes:

[0035] The connecting bracket is hinged at one end to the mounting shell;

[0036] A pressing cylinder, rotatably disposed at one end of the connecting frame along its axis, and in contact with the winding portion of the bandage; and

[0037] A torsion spring is provided at the hinge point between the connecting frame and the mounting housing.

[0038] Compared with the prior art, the present invention has the following beneficial effects:

[0039] 1. When using this bracket, the patient places their thigh on the leg rest, with their lower leg and ankle relaxed naturally, so that the lower leg is flush with the first guide rod. The height of the first guide rod is adjusted according to the length of the lower leg via a telescopic component, and the angle of the second guide rod is adjusted according to the angle of the ankle. After adjustment, the angle of the second guide rod is fixed by a locking component. Then, a mounting ring slides along the second and first guide rods. During the sliding process, the mounting ring moves along the axis of the patient's foot and lower leg, and its movement trajectory can be changed according to the angle of the ankle. During the movement, the bandaging mechanism bandages the patient's foot and lower leg as a whole, improving the bandaging efficiency and increasing the applicability of the bracket.

[0040] 2. By operating the handle, the mounting ring in the bracket moves along the patient's foot and lower leg axis. Squeezing the handle triggers the control switch, starting the drive motor and rotating the drive gear. During rotation, the drive gear, in conjunction with the gear ring, causes the movable ring to rotate within the mounting ring along its axis, thus moving the roll and bandaging the patient's leg. This effectively improves bandaging efficiency. The bandage is also tightened by the compression component during movement, enhancing the bandaging effect. Furthermore, the roll is easy to disassemble, further improving bandaging efficiency. Attached Figure Description

[0056] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0057] Example:

[0058] like Figure 1 , 2 As shown, the present invention provides a foot wound dressing support, including a lifting base 101, a leg support 102 disposed on the lifting base 101, a first guide rod 106 obliquely arranged at one end of the leg support 102, the first guide rod 106 and the leg support 102 being connected by a telescopic assembly, the telescopic assembly including a telescopic rod 105, one end of the telescopic rod 105 being fixedly connected to the leg support 102, and the other end being fixedly connected to the first guide rod 106. A positioning cylinder 104 is disposed on the first guide rod 106, and a positioning rod 103 is disposed at one end of the leg support 102, the positioning rod 103 slidingly passing through the positioning cylinder 104 along its axis.

[0059] In use, the height of the leg support 102 can be adjusted via the lifting base 101. The patient's leg is then placed on the leg support 102, causing the lower leg to be tilted and parallel to the first guide rod 106. The height of one end of the first guide rod 106 is adjusted by controlling the extension and retraction of the telescopic rod 105, moving it to the patient's ankle position. During movement, the first guide rod 106 is positioned by the cooperation of the positioning rod 103 and the positioning cylinder 104, improving the stability of the support when supporting the patient's leg. In some embodiments, the telescopic rod 105 can be electrically controlled, hydraulically controlled, or fixed with bolts or set screws, depending on the actual needs.

[0060] like Figure 2 , 3As shown, in this embodiment, a second guide rod 107 is provided at one end of the first guide rod 106. The second guide rod 107 and the first guide rod 106 are connected by a locking assembly. The locking assembly adjusts the angle between the second guide rod 107 and the first guide rod 106. The locking assembly includes a first gear 201 provided at one end of the first guide rod 106 and a second gear 203 provided at one end of the second guide rod 107. A threaded cylinder 202 is provided on the first gear 201. The second gear 203 is slidably sleeved on the threaded cylinder 202 and meshes with the first gear 201. A threaded knob 204 is threaded through the threaded cylinder 202 and screwed to it. The threaded knob 204 limits the position of the second gear 203.

[0061] The second gear 203 can be released by loosening the threaded knob 204. Then, the second gear 203 can be rotated along the threaded cylinder 202 according to the angle of the patient's ankle so that the second guide rod 107 can be parallel to the patient's foot. After adjustment, the threaded knob 204 can be tightened so that the second gear 203 can re-engage with the first gear 201, thereby adjusting and fixing the angle between the second guide rod 107 and the first guide rod 106 for convenient subsequent use.

[0062] like Figure 2 , 3 As shown, in this embodiment, the bracket further includes a mounting ring 301. The mounting ring 301 is slidably disposed on the first guide rod 106 and the second guide rod 107 along the trajectory formed by the cooperation of the first guide rod 106 and the second guide rod 107. A through groove 303 is provided on the mounting ring 301, and a guide wheel 304 is disposed in the through groove 303. A guide groove 108 is provided on both the first guide rod 106 and the second guide rod 107, and the guide wheel 304 is engaged in the guide groove 108.

[0063] After adjusting the angle between the second guide rod 107 and the first guide rod 106, the mounting ring 301 can be moved along the second guide rod 107 and the first guide rod 106. During the movement, the mounting ring 301 is positioned by the guide wheel 304 cooperating with the guide groove 108, making the movement of the mounting ring 301 more stable, preventing deviation during bandaging, and improving the bandaging effect. When the mounting ring 301 passes the connection between the first guide rod 106 and the second guide rod 107, the guide wheel 304 can move between the two sets of guide grooves 108, and cause the mounting ring 301 to deflect at a certain angle to adapt to the angle of the patient's ankle.

[0064] like Figure 4 , 5As shown, in this embodiment, a bandaging mechanism is provided inside the mounting ring 301 to bandage the patient's foot. The bandaging mechanism includes a movable ring 401 rotatably disposed inside the mounting ring 301 along its axis. A drive assembly connected to the movable ring 401 is provided inside the mounting ring 301, driving the movable ring 401 to rotate within the mounting ring 301. The drive assembly includes a drive motor 307 disposed on the mounting ring 301, a drive gear 308 disposed on the output shaft of the drive motor 307, a gear ring 402 disposed on the movable ring 401, the drive gear 308 meshing with the gear ring 402, a handle 302 disposed on the mounting ring 301, a control switch 306 disposed on the handle 302 to control the start and stop of the drive motor 307, and a hinged grip 305 disposed on the mounting ring 301. When the grip 305 rotates along its hinge point with the mounting ring 301, it triggers the control switch 306.

[0065] The mounting ring 301 can be controlled to move along the first guide rod 106 and the second guide rod 107 by operating the handle 302. When operating the handle 302, the grip 305 can be squeezed to trigger the control switch 306, thereby controlling the start and stop of the drive motor 307. During the start-up process of the drive motor 307, the drive gear 308 is controlled to rotate, and then the engagement between the drive gear 308 and the gear ring 402 drives the movable ring 401 to rotate along its axis within the mounting ring 301.

[0066] like Figure 4 , 6 As shown, the bandaging mechanism also includes a roll 601, which is rotatably mounted on a movable ring 401 along its axis and connected to the movable ring 401 via a mounting assembly. A bandage 602 is wound on the roll 601. The mounting assembly includes a mounting shell 403 fixedly mounted on a movable ring 401. A baffle 405 is provided at one opening of the mounting shell 403. A crossbar 501 is slidably mounted inside the mounting shell 403 along its axis. Both ends of the crossbar 501 are exposed outside the mounting shell 403. A pressure plate 503 is provided on the crossbar 501. A pressing plate 504 is provided at one end of the crossbar 501. Mounting brackets 404 are fixedly mounted on both the mounting shell 403 and the crossbar 501. The two sets of mounting brackets 404 are arranged opposite to each other. Fixed posts 502 are provided on opposite sides of the two sets of mounting brackets 404. Both ends of the drum 601 are rotatably locked onto the two sets of fixed posts 502. An elastic member 505 is provided between the baffle 405 and the pressure plate 503 for abutment.

[0067] As the movable ring 401 rotates, it drives the roll 601 to rotate, thereby bandaging the patient's wound with the moving bandage 602. When the bandage 602 on the roll 601 is used up, the crossbar 501 can be slid along its axis within the mounting housing 403 by pressing the button 504. During the movement, the crossbar 501 compresses the elastic element 505 through the cooperation of the pressure plate 503 and the baffle 405, thereby increasing the distance between the two sets of mounting brackets 404. This allows the used roll 601 to be disassembled. After disassembly, a new roll 601 is placed between the two sets of mounting brackets 404. Under the restoring ability of the elastic element 505, the two sets of fixing posts 502 are re-engaged into the roll 601, completing the installation of the roll 601.

[0068] like Figure 4 , 6 As shown, in this embodiment, a pressing assembly is provided on the mounting housing 403. The pressing assembly contacts the bandage 602 to tighten the bandage 602 during bandaging. The pressing assembly includes a connecting frame 701 with one end hinged to the mounting housing 403. One end of the connecting frame 701 is provided with a pressing cylinder 702 that can rotate along its axis. The pressing cylinder 702 contacts the winding portion of the bandage 602. A torsion spring 703 is provided at the hinge point between the connecting frame 701 and the mounting housing 403.

[0069] The torsion spring 703 ensures that the connecting frame 701 always maintains a force close to the drum 601, allowing the pressing cylinder 702 to press against the surface of the bandage 602. This increases the friction required for the drum 601 to rotate, ensuring the bandage 602 remains taut when wrapped around the patient's legs and feet, preventing it from loosening and improving the bandaging effect. Furthermore, during bandaging, the ring 301 can be repeatedly installed along the first guide rod 106 and the second guide rod 107 at the ankle, causing the bandage 602 to be crisscrossed around the ankle. This increases the bandage's firmness, preventing subsequent loosening and further enhancing the bandaging effect.

[0070] Specific usage and beneficial effects of the present invention:

[0071] When using this bracket, the patient places their thigh on the leg rest 102, with their lower leg and ankle relaxed naturally, so that the lower leg is flush with the first guide rod 106. The height of the first guide rod 106 is adjusted according to the length of the lower leg via the telescopic rod 105, and the angle of the second guide rod 107 is adjusted according to the angle of the ankle. After adjustment, the second gear 203 is engaged with the first gear 201 by rotating the threaded knob 204, thus fixing the angle of the second guide rod 107. Then, the mounting ring 301 slides along the second guide rod 107 and the first guide rod 106. During the sliding process, the mounting ring 301 moves along the axis of the patient's foot and lower leg, and can change its movement trajectory according to the angle of the ankle. During the movement, the bandaging mechanism bandages the patient's foot and lower leg as a whole, improving the bandaging efficiency and increasing the applicability of the bracket.

[0072] By operating the mounting ring 301 in the bracket via the handle 302, the movement along the patient's foot and lower leg axis can be controlled by gripping the handle 305 to trigger the control switch 306, thereby starting the drive motor 307 and driving the drive gear 308 to rotate. During the rotation of the drive gear 308, through its cooperation with the gear ring 402, the movable ring 401 rotates within the mounting ring 301 along its axis, thereby driving the roll 601 to move and bandage the patient's leg with the bandage 602, effectively improving the bandaging efficiency. During the movement of the bandage 602, the connecting frame 701 is controlled to rotate via the torsion spring 703, so that the pressing cylinder 702 at one end of the connecting frame 701 presses the bandage 602 tightly to prevent the bandage 602 from loosening, improving the bandaging effect. Furthermore, the disassembly of the roll 601 is relatively convenient, effectively improving the bandaging efficiency.

[0073] The foregoing has shown and described the basic principles and main features of the present invention and its advantages. It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments.
