[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Reference Figure 1 - Figure 2 This utility model provides an embodiment of an adjustable limb support frame for burn dressing changes, including a dressing chair 1. Patients with burns of the limbs can sit on the dressing chair 1 during dressing changes. Armrests 2 are fixedly connected to the upper surface of the dressing chair 1. Two sets of armrests 2 are symmetrically distributed about the center line of the dressing chair 1. The armrests 2 are higher than ordinary armrests; when a patient of normal height places their arm flat, it will be level with the armrest 2. Adjustment components are provided inside the armrests 2. In traditional dressing chairs 1, the patient's arm rests directly on the armrest, and a support plate at the bottom can support the patient's legs. During dressing changes, the injured area of the patient easily comes into contact with the surface of the dressing chair 1.
[0032] Reference Figure 1 - Figure 3 The adjustment component includes an extension plate 31. There are two sets of extension plates 31, which are evenly distributed longitudinally on the handrail 2. The upper extension plate 31 corresponds to the patient's hand, and the lower extension plate 31 corresponds to the patient's leg. A positioning plate 32 is slidably connected to the inner wall of the handrail 2. A slider 33 is fixedly connected to the left surface of the positioning plate 32. A pull ring is fixed to the left end of the slider 33 for easy pulling. A locking block 34 is elastically connected to the inner wall of the extension plate 31 through a compression spring 35. The locking block 34 is located at the rear end of the extension plate 31. A slot 301 is opened on the inner wall of the handrail 2. The locking block 34 and the slot 301 fit together. There are multiple sets of slots 301, which are evenly distributed in the front-back direction. A rotating shaft 36 is rotatably connected to the front end of the lower surface of the extension plate 31. A fixing component is provided on the lower surface of the rotating shaft 36.
[0033] Reference Figure 1 , Figure 2 , Figure 4 The fixing component includes a support block 41, which is elongated. A strap 42 is fixedly connected to the right end of the lower surface of the support block 41. When the strap 42 is adjusted to a suitable position, it can bind the wrist or ankle of the burn patient, keeping the burn patient's arm or leg suspended and preventing the burn area from contacting the device. The outer wall of the strap 42 is provided with Velcro 43, which is evenly distributed on the left and right sides of the strap 42. One side is smooth and the other side is hooked. The smooth and hooked sides can be bonded together. A slot 401 is opened in the upper section of the left surface of the strap 42. The bottom end of the strap 42 can pass through the slot 401. Then, through the cooperation of the smooth and hooked sides of the Velcro 43, the strap 42 can be made into an adjustable ring, thereby binding the wrist or ankle of the burn patient.
[0034] Reference Figure 1 - Figure 3 The extension plate 31 is slidably connected to the front surface of the armrest 2 and moves in the front-back direction. The slider 33 is slidably connected to the left surface of the armrest 2 and moves in the front-back direction. One end of the compression spring 35 is fixedly connected to the inner wall of the bottom end of the extension plate 31, and the other end of the compression spring 35 is fixedly connected to the lower surface of the locking block 34. The locking block 34 is slidably connected to the upper surface of the extension plate 31. When the locking block 34 moves downward, it will compress the compression spring 35 to generate a reaction force. The right surface of the positioning plate 32 is opened. There are notches, and multiple sets of notches are provided, which are evenly distributed front and back. The locking block 34 is inserted into the notch. The front end of the upper surface of the locking block 34 is set as an inclined surface. When the inclined surface of the locking block 34 is squeezed, it will move downward to release the obstruction. The locking block 34 is inserted into the inner wall of the locking slot 301, which can limit the extension plate 31 in one direction. The extension plate 31 can only extend forward and cannot retract backward. When the positioning plate 32 squeezes the inclined surface of the locking block 34, the locking block 34 is pressed downward into the extension plate 31, which can release the limit and allow the extension plate 31 to move backward.
[0035] Reference Figure 1 , Figure 2 , Figure 4 The left end of the upper surface of the support block 41 is fixedly connected to the lower surface of the rotating shaft 36. The upper section of the strap 42 is wider than the lower section, and the width of the slot 401 is wider than the lower section of the strap 42.
[0036] Working principle: First, the burn patient sits on the dressing chair 1. Then, the position of the strap 42 is adjusted according to the length of the patient's arm or leg. During adjustment, the extension plate 31 is pulled forward. When the extension plate 31 moves forward, the inclined surface of the locking block 34 is squeezed, and the locking block 34 moves downward and disengages from the locking slot 301 to release the obstruction. It also squeezes the compression spring 35 to generate a reaction force. When the extension plate 31 moves to the appropriate position, the compression spring 35 pushes out the locking block 34, so that the locking block 34 and the locking slot 301 are inserted and limited. Then, the patient's arm or leg is raised, and the strap 42 is used to wrap around the lower part of the patient's wrist or ankle. The lower part of the strap 42 is passed through the slot 401, and then the smooth surface and hook surface of the Velcro 43 are glued together to fix the patient's wrist or ankle.
[0037] Once secured, the dressing can be changed on the patient's arm or leg. After the dressing is changed, peel the smooth side of the Velcro 43 off the hook side, and then pull the Velcro 43 out of the slot 401 so that the patient's wrist and ankle can be lowered. Then the patient can leave the dressing chair 1.
[0038] Subsequently, medical staff can move the slider 33 backward to move the positioning plate 32 backward and press the inclined surface of the locking block 34, so that the locking block 34 moves downward and retracts into the extension plate 31 to release the obstruction. Then, the extension plate 31 is moved backward to the initial position for convenient subsequent use.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
