Description

Technical Field

[0001] This utility model relates to the field of orthopedic nursing technology, and in particular to a leg fixation support device. Background Technology

[0002] Orthopedics is one of the most common departments in major hospitals. It mainly studies the anatomy, physiology and pathology of the musculoskeletal system and uses methods such as drugs, surgery and physical therapy to maintain and develop the normal shape and function of this system. In orthopedic nursing, it is crucial to keep the leg stable and in the proper position for patients with fractures, joint dislocations and postoperative recovery.

[0003] Traditional leg immobilization support devices, while having some adjustment capabilities, are always adjusted by medical staff before use. However, patients cannot adjust the height or angle according to their own needs during use, resulting in poor comfort. Therefore, we have proposed a leg immobilization support device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing leg fixation support devices, which cannot adjust the height or angle according to the patient's actual situation during use, resulting in poor comfort. Therefore, this invention proposes a new leg fixation support device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A leg support device includes a U-shaped block. A support tube is fixedly connected to the top of the U-shaped block. A connecting tube is slidably connected inside the support tube. The top of the connecting tube extends above the support tube and is fixedly mounted on a first rotating seat. A support rod is rotatably connected to one side of the first rotating seat. A second rotating seat is fixedly connected to one end of the support rod. A first connecting rod is rotatably connected to the bottom of the second rotating seat. A second connecting rod is rotatably mounted at the bottom end of the first connecting rod. An arc-shaped block is fixedly mounted at the bottom of the second connecting rod. Two connecting rings are symmetrically arranged at the bottom of the arc-shaped block, and a strap is fixedly connected to one of the connecting rings. The device also includes:

[0007] The fixing component is mounted on the U-shaped block and is used to fix the device to the hospital bed;

[0008] An adjustment component, which is installed on the connecting pipe, is used to adjust the angle between the support rod and the connecting pipe;

[0009] The lifting assembly, mounted on the U-shaped block, is used to adjust the height of the device.

[0010] In one possible design, the fixing component includes an extrusion plate, a groove is provided on the inner wall of a recess on one side of the U-shaped block, the extrusion plate is located in the recess and slidably connected to the groove, a threaded hole is provided at the bottom of the U-shaped block, a first threaded rod is threadedly connected to the threaded hole, and the top of the first threaded rod is rotatably connected to the bottom of the extrusion plate.

[0011] In one possible design, anti-slip pads are provided on the top inner wall of the U-shaped block and the top of the extrusion plate.

[0012] In one possible design, the adjusting assembly includes a second fixing block, which is fixedly sleeved on the outer wall of the connecting pipe. An electric cylinder is rotatably connected to the outer wall of the second fixing block. A first fixing block is fixedly sleeved on the outer wall of the support rod. The output end of the electric cylinder is rotatably connected to the first fixing block.

[0013] In one possible design, the lifting assembly includes a second threaded rod, a groove is provided on the top of the U-shaped block, the second threaded rod rotates with the bottom inner wall of the groove, the bottom of the connecting pipe extends into the interior of the groove, the bottom of the connecting pipe is rotatably connected to an internally threaded pipe, the second threaded rod is threaded through the internally threaded pipe and extends into the interior of the connecting pipe, a motor is fixedly installed at the bottom of the U-shaped block, and the output end of the motor extends into the interior of the U-shaped block and is fixedly connected to the second threaded rod.

[0014] In one possible design, both the inner wall of the support tube and the inner wall of the groove are provided with limiting grooves, and the outer wall of the connecting tube is fixedly provided with a limiting block, which extends into the interior of the limiting groove and is slidably connected to the limiting groove.

[0015] In one possible design, one side of the strap is provided with a sponge pad to increase comfort, and the other side of the strap is provided with a Velcro fastener, which is divided into a female side and a male side. One end of the strap passes through another connecting loop and is folded in half, and the female side and male side of the Velcro fastener are bonded together.

[0016] In one possible design, a PLC controller is fixedly mounted on one side of the U-shaped block, and a control panel for easy operation by a bedridden patient is connected to the bottom of the U-shaped block via an extension line. The control panel is electrically connected to the PLC controller, and the PLC controller is electrically connected to the electric cylinder and motor.

[0017] In this application, firstly, the device is fixed to the hospital bed by a fixing component, which includes a compression plate and a first threaded rod. When it is necessary to fix the device to the hospital bed, medical staff can slide the compression plate to a suitable position and tighten the first threaded rod to make the compression plate in close contact with the hospital bed. The anti-slip pad increases the friction of the contact surface and further improves the stability of the fixation.

[0018] Next, the appropriate angle is adjusted by adjusting the components, which include a second fixing block, an electric cylinder, and a first fixing block. When it is necessary to adjust the angle between the support rod and the connecting tube, medical staff can activate the electric cylinder. The output end of the electric cylinder pushes or pulls the first fixing block, thereby driving the support rod to rotate around the first rotating seat, thus adjusting the angle between the support rod and the connecting tube. This design allows the device to be personalized according to the leg shape and support needs of different patients.

[0019] Meanwhile, the lifting assembly can adjust the height of the device. The lifting assembly includes a second threaded rod, an internal threaded tube, and a motor. When the height of the device needs to be adjusted, medical staff can start the motor so that its output end drives the second threaded rod to rotate. Since the second threaded rod is threaded through the internal threaded tube, the rotation of the second threaded rod will be converted into the lifting and lowering movement of the connecting tube in the support tube. The setting of the limiting groove and the limiting block ensures the stability of the connecting tube during the lifting and lowering process.

[0020] Then, the strap is passed through the connecting loop and folded in half. The female and male sides of the Velcro are then attached together to suspend the patient's leg. The sponge padding increases the comfort between the strap and the skin and reduces the pressure during fixation.

[0021] Finally, during use, patients can fine-tune the adjustment and lifting components through the control panel of the extended line connection according to their own actual situation and needs, so that the device can achieve the best fixation effect and comfort.

[0022] Beneficial effects: In this utility model, the leg fixation support device can meet the needs of different patients for leg fixation angle by adjusting the components, thereby improving the flexibility and applicability of the device;

[0023] In this utility model, the leg fixation support device can precisely adjust the height of the device through the lifting component, allowing the patient to make fine adjustments according to their own comfort, further improving the convenience and comfort of use.

[0024] In this utility model, the leg fixation support device, through the integration of the control panel and PLC controller, not only makes the operation more convenient, but also makes it easier for bedridden patients to operate on their own, thus improving the convenience of use and the patient's self-care ability.

[0025] In this invention, the adjustable components meet the different needs of patients for leg fixation angle.
