Description

Technical Field

[0001] This utility model relates to the field of elevation pad technology, specifically a patient lower limb elevation pad. Background Technology

[0002] Lower limb elevation pads are commonly used in clinical nursing to prevent deep vein thrombosis, reduce limb swelling, and promote postoperative recovery. They are widely used in departments such as orthopedics, neurology, and intensive care.

[0003] Traditional leg-elevation pads are mostly fixed structures or only support single-angle adjustment. When the lower leg is raised for too long, the thigh remains suspended and does not provide support to the bottom of the thigh. Furthermore, prolonged elevation can easily cause thigh cramps, resulting in patient discomfort and affecting the patient's rehabilitation. Therefore, we propose a lower limb elevation pad for patients. Utility Model Content

[0004] The purpose of this invention is to provide a lower limb elevation pad for patients, in order to solve the problems mentioned in the background art, that traditional elevation pads are mostly fixed structures or only support a single angle adjustment, and that after the lower leg is raised for too long, the thigh remains suspended and does not provide support for the bottom of the thigh. Moreover, if the time is too long, it is easy to cause thigh cramps, causing discomfort to the patient and affecting the patient's rehabilitation effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a patient lower limb elevation pad, comprising an elevation pad body and an elevation plate, the elevation plate being movably installed inside the elevation pad body, a guide rail being fixedly installed on one side of the surface of the elevation pad body, a limit groove being formed on the surface of the guide rail, a sliding rod being slidably connected to the surface of the limit groove, a fixing column being fixedly installed on the top surface of the elevation plate, a buffer spring being provided inside the fixing column, a top cover being fixedly installed on the top of the buffer spring, a connecting rod being fixedly installed on one side of the surface of the elevation plate, a top cover being fixedly installed on one side of the surface of the connecting rod, and a front lifting plate and a side lifting plate being movably installed on the top surface of the elevation pad body.

[0006] The bottom surfaces of the front lifting plate and the side lifting plate are provided with positioning holes.

[0007] The connecting rods are evenly distributed on one side of the raised plate surface and are L-shaped. The raising and lowering of the raised plate drives the connecting rods to rise and fall synchronously.

[0008] One side of the slide bar penetrates the interior of the lifting pad body and is fixedly connected to the surface of the lifting plate. The lifting plate is raised and lowered inside the lifting pad body through the limiting groove.

[0009] The positioning holes are perpendicular to the top cover one and top cover two, and the lifting plate raises and lowers, which drives the front lifting plate and the side lifting plate to rise and fall synchronously on the top surface of the lifting pad body.

[0010] There is a height difference between the front lifting plate and the side lifting plate, and the front lifting plate and the side lifting plate are adjusted up and down in sequence on the top surface of the lifting pad body by the top cover one and the top cover two.

[0011] The guide rails consist of three sets: one set is located on the outer surface of the raised pad body, and the other two sets are located on both sides of the inner wall of the raised pad body, and are parallel and corresponding to both sides of the raised plate surface.

[0012] This utility model has at least the following beneficial effects:

[0013] 1. The two sets of side lifting plates have a height difference with the front lifting plate. The stepped lifting of the top cover one and the top cover two can form an arc-shaped support structure with "high in the middle and low on both sides", which can adapt to the physiological curvature of the lower limbs and avoid excessive stretching of the joints.

[0014] 2. After the positioning holes at the bottom of the front and side lifting boards are engaged with the top cover one and top cover two, a stable "three-point support" structure is formed. The front lifting board supports the front of the lower limb, while the side lifting board fixes the inner and outer sides of the lower limb, preventing the limb from rolling or rotating. This is especially suitable for anti-spasticity positioning of hemiplegic patients. After lifting the front lifting board upwards, the side lifting board is lifted upwards further, so that a certain height difference is always maintained between the side and front lifting boards. This effectively provides support to the bottom of the patient's thigh, preventing the thigh from remaining suspended without proper support when the lower leg is raised for too long. Prolonged elevation of the lower leg can also easily cause thigh cramps, resulting in patient discomfort and affecting the patient's rehabilitation. Attached Figure Description

[0021] 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.

[0022] Please see Figures 1 to 4 This utility model provides a technical solution: a patient lower limb elevation pad, including an elevation pad body 100 and an elevation plate 200. The elevation plate 200 is movably installed inside the elevation pad body 100. A guide rail 101 is fixedly installed on one side of the surface of the elevation pad body 100. There are three sets of guide rails 101: one set is located on the outer surface of the elevation pad body 100, and the other two sets are located on both sides of the inner wall of the elevation pad body 100, parallel and corresponding to the two sides of the surface of the elevation plate 200. A limiting groove 102 is formed on the surface of the guide rail 101. A sliding rod 103 is slidably connected to the surface of the limiting groove 102. One side of the sliding rod 103 penetrates the interior of the elevation pad body 100 and is fixedly connected to the surface of the elevation plate 200. The limiting groove 102 drives the elevation plate 200 to rise and fall within the elevation pad body 100 for adjustment. A fixed column 201 is fixedly installed on the top surface of the raised plate 200. A buffer spring 202 is installed inside the fixed column 201. A top cover 203 is fixedly installed on the top of the buffer spring 202. A connecting rod 204 is fixedly installed on one side of the surface of the raised plate 200. The connecting rod 204 is evenly distributed on one side of the surface of the raised plate 200 and is L-shaped. The raising plate 200 raises and lowers the connecting rod 204 synchronously. A top cover 205 is fixedly installed on one side of the surface of the connecting rod 204. A front lifting plate 104 and a side lifting plate 105 are movably installed on the top surface of the raised pad body 100. There is a height difference between the front lifting plate 104 and the side lifting plate 105. The front lifting plate 104 and the side lifting plate 105 are raised and lowered sequentially on the top surface of the raised pad body 100 through the top cover 203 and the top cover 205.

[0023] The bottom surfaces of the front lifting plate 104 and the side lifting plate 105 are provided with positioning holes 106. The positioning holes 106 are perpendicular to the top cover 203 and the top cover 205. The lifting plate 200 is raised and lowered, which drives the front lifting plate 104 and the side lifting plate 105 to rise and fall synchronously on the top surface of the lifting pad body 100.

[0024] Working principle: The limiting groove 102 of the outer guide rail 101 provides positioning support for the slide rod 103 when it slides upward along the limiting groove 102. This is used to adjust the lifting height of the front lifting plate 104 and the side lifting plate 105. The vertical displacement of the slide rod 103 is converted into the upward force of the lifting plate 200 through the lever principle. The three sets of guide rails 101 form a stable three-dimensional guiding structure.

[0025] When the lifting plate 200 rises, the buffer spring 202 inside the top fixing column 201 lifts the main lifting plate 104 through the top cover 203. The buffer spring 202 reduces the impact force with the top cover 203, providing a certain degree of protection. At the same time, the connecting rod 204 drives the top cover 205 to rise, lifting the side lifting plates 105 on both sides. Due to the height difference between the top cover 203 and the top cover 205, the main lifting plate 104 reaches the target height before the side lifting plates 105, forming an arc surface that is "high in the middle and low on both sides," which fits the natural bending curve of the popliteal fossa of the lower limbs.

[0026] When the buffer spring 202 first lifts the front lifting plate 104 to a certain height, the connecting rod 204 and the top cover 205 also rise synchronously, generating an upward thrust with the bottom of the side lifting plate 105, which in turn lifts the side lifting plate 105, so that a certain height difference is always maintained between the side lifting plate 105 and the front lifting plate 104. This effectively provides some support for the patient's thigh bottom, preventing the thigh from remaining suspended in the air when the lower leg is raised for too long, thus failing to provide support for the thigh bottom. Furthermore, prolonged elevation can easily cause thigh cramps, resulting in patient discomfort and affecting the patient's rehabilitation effect.
