Description
Technical Field
[0001] This utility model relates to the technical field of medical assistive devices, and in particular to a height-adjustable lower limb brace. Background Technology
[0002] After treating patients with leg or foot injuries, doctors typically use tools such as a lower limb elevation pad disclosed in utility model patent CN219207812U and a multifunctional lower limb elevation pad disclosed in utility model patent CN209596098U to elevate and support the patient's legs.
[0003] However, during use, it was found that the existing elevation pad has a relatively simple structure, which is not convenient for adjusting the height of the patient's legs. In addition, some patients experience leg swelling after treatment. The existing elevation pad is not convenient for adjusting the depth and width of the groove according to the thickness of the patient's legs, resulting in poor practicality. Therefore, there is an urgent need for a height-adjustable lower limb brace to improve the above problems. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a height-adjustable lower limb brace that clamps the clamping mechanism to the edge of the hospital bed, adjusts the height of the adjustment mechanism through the support mechanism, and then adjusts the adjustment mechanism according to the thickness of the patient's legs, so that the adjustment mechanism supports and limits the patient's legs, thereby improving the practicality of the device.
[0005] This utility model discloses a height-adjustable lower limb brace, including a clamping mechanism; it also includes a support mechanism and an adjustment mechanism, wherein the support mechanism is mounted on the clamping mechanism and the adjustment mechanism is mounted on the support mechanism;
[0006] The clamping mechanism limits the support mechanism, the support mechanism adjusts the height of the adjusting mechanism, and the adjusting mechanism supports and limits the patient's legs.
[0007] The clamping mechanism is clamped to the edge of the hospital bed, and the height of the adjustment mechanism is adjusted by the support mechanism. Then, the adjustment mechanism is adjusted according to the thickness of the patient's legs, so that the adjustment mechanism can support and limit the patient's legs, thereby improving the practicality of the equipment.
[0008] Preferably, the support mechanism includes a base, a first clamping plate, a slide rail, a second clamping plate, a first lead screw, and a first rotating handle. The first clamping plate and the slide rail are both installed at the bottom of the base. The second clamping plate is slidably installed on the slide rail. One end of the first lead screw is rotatably installed on the first clamping plate, and the other end of the first lead screw passes through the second clamping plate. The surface of the first lead screw is threadedly connected to the second clamping plate. The first rotating handle is installed on the other end of the first lead screw. By rotating the first rotating handle, the second clamping plate slides on the slide rail toward the first clamping plate via the first lead screw. The first and second clamping plates clamp the edge of the hospital bed, thereby improving the stability of the equipment.
[0009] Preferably, the support mechanism includes a support rod, a flange, a tray, and a lifting mechanism. One end of the support rod is mounted on the base, the flange is mounted on the other end of the support rod, the lifting mechanism is mounted on the flange, and the tray is mounted on the lifting mechanism. According to the treatment requirements, the angle of the tray is adjusted, and then the lifting mechanism is mounted on the flange by threads. After that, the height of the tray is adjusted by the lifting mechanism, thereby improving the practicality of the equipment.
[0010] Preferably, the lifting mechanism includes a support base, multiple sets of telescopic rods, a second lead screw, a second rotary handle, and a limiting mechanism. The support base is bolted to the flange. The bottom ends of the multiple sets of telescopic rods are all mounted on the top of the support base, and the top ends of the multiple sets of telescopic rods are all mounted on the bottom of the pallet. The top end of the second lead screw is rotatably mounted on the bottom of the pallet, and the bottom end of the second lead screw passes through the support base, with its surface threaded to the center of the support base. The second rotary handle is mounted on the bottom of the second lead screw, and the limiting mechanism is mounted on the top of the second lead screw. By rotating the second rotary handle, the height of the pallet is adjusted via the second lead screw drive and the multiple sets of telescopic rods. The limiting mechanism then limits the second lead screw to maintain the height of the pallet, thereby improving the practicality of the equipment.
[0011] Preferably, the limiting mechanism includes a support plate, a pin, and a buffer pad. The bottom end of the support plate is provided with multiple sets of grooves, and each set of grooves contains an iron sheet. The support plate is mounted on the top of the second lead screw, the pin is slidably mounted on the support plate, and a permanent magnet is provided at the top of the pin. The buffer pad is mounted on the top of the permanent magnet. After adjusting the height of the support plate, the permanent magnet is inserted into a set of grooves by sliding the pin upwards, and the permanent magnet is attracted to the iron sheet. At the same time, the buffer pad reduces the impact force between the permanent magnet and the iron sheet, thereby improving the practicality of the equipment.
[0012] Preferably, the adjustment mechanism includes a first support pad, an airbag, two sets of limiting plates, a bidirectional electric cylinder, two sets of fixing frames, multiple sets of limiting posts, and two sets of second support pads. The first support pad and the airbag are both installed on the top of the support plate, and the top of the airbag is connected to the bottom of the first support pad. The two sets of limiting plates are slidably installed on the support plate, and are located at the left and right ends of the first support pad, respectively. Each set of limiting plates has a through hole at its top. The bidirectional electric cylinder is installed at the bottom of the limiting plates, and its left and right ends are connected to the two sets of limiting plates, respectively. Multiple sets of limiting posts are installed at the bottom of the two sets of fixing frames, and each set of fixing frames is provided with a first Velcro fastener. Each set of second support pads is provided with a second Velcro fastener. The first Velcro straps are attached to the two sets of fixing frames respectively. When the patient's legs are thick or swollen, the bidirectional electric cylinder extends, moving the two sets of limiting plates away from the first support pad. Then, multiple sets of limiting posts are inserted into the perforations of the two sets of limiting plates. Next, the second Velcro straps on the two sets of second support pads are attached to the first Velcro straps of the two sets of fixing frames respectively. The first support pad and the two sets of second support pads work together to support the patient's legs. When the patient's legs are thin or the swelling subsides, the air in the airbag is expelled, causing the airbag to pull down to the middle of the first support pad. Then, the bidirectional electric cylinder contracts, causing the two sets of limiting plates to squeeze the left and right ends of the first support pad, so that the first support pad supports the patient's legs, thereby improving the support and limiting effect of the device on the patient's legs.
[0013] Preferably, an exhaust valve is provided at the bottom of the airbag; connecting the exhaust valve to an exhaust device facilitates the intake of air into the airbag or the exhaust of air from the airbag, thereby improving the practicality of the device.
