Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a lower limb protection device. Background Technology

[0002] Lower limb positioning pads are devices used in medical care to help patients maintain the correct position of their lower limbs. They come in various shapes to suit different needs. Common shapes include rectangular pads, which can be placed under the lower limbs to elevate them; U-shaped pads, which can wrap around and stabilize areas such as the knee joint; and trapezoidal pads, which have a slope and are often used to elevate the lower limbs to promote blood return, reduce venous pressure in the lower limbs, help relieve lower limb swelling, and reduce the risk of deep vein thrombosis. This is especially important for patients who are bedridden for extended periods, have undergone lower limb fracture surgery, or have lower limb vascular disease.

[0003] Lower limb positioning pads are typically made of soft yet supportive materials, such as high-density foam, which provides stable support and is not easily deformed. Memory foam can mold to the contours of the lower limbs, distributing pressure and providing a comfortable support experience for patients. The outer cover is usually made of cotton fabric, which is soft, skin-friendly, and breathable, ensuring patient comfort and facilitating cleaning and disinfection. Some positioning pads requiring waterproofing have an additional waterproof coating inside the cotton cover or use waterproof synthetic materials.

[0004] In actual use, after placing the lower limbs on the lower limb positioning pad, the patient will feel tired if they maintain one position. When the patient adjusts their position, the lower limbs cannot be finely adjusted according to the body posture, or the lower limbs do not match the body posture after adjustment, which causes the limitations of the existing lower limb positioning pads.

[0005] Therefore, there is an urgent need to improve the existing lower limb positioning pads. Summary of the Invention

[0006] This invention addresses the technical problem in the prior art where, after the lower limbs are placed in a lower limb positioning pad, it is impossible to make minor adjustments to the lower limbs according to the body. The purpose is to provide a lower limb protection device.

[0042] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0043] like Figures 1-4 As shown, a lower limb protection device mainly consists of a base 1 and lower limb protection components 2. The base 1 serves as the basic support structure for the entire device, and is provided with a first groove 101 and multiple blind holes 102. The blind holes 102 are arranged along the length of the first groove 101 for installing multiple lower limb protection components 2. The lower limb protection components 2 are rotatably connected to the blind holes 102 on the base 1 via a rotating shaft 201, enabling rotational adjustment at a certain angle to adapt to different usage requirements.

[0044] The base 1 is made of high-strength engineering plastic or metal to ensure sufficient stability and durability. The first groove 101 on the base 1 is precision machined according to the bottom contour of the lower limb protection component 2 to ensure a tight fit and stable installation of the lower limb protection component 2 on the base 1. The surface of the first groove 101 is smoothed to avoid wear on the lower limb protection component 2.

[0045] A blind hole 102 is located at a specific position in the first groove 101. Its depth and diameter are designed according to the dimensions of the rotating shaft 201. A bearing is installed inside the blind hole 102. The blind hole 102 is machined with high precision to ensure that the bearing is precisely installed inside the blind hole 102. The rotating shaft 201 is installed inside the bearing, so that the rotating shaft 201 can rotate and is firmly installed on the base 1, while ensuring the smoothness of the lower limb protection component 2 when rotating around the rotating shaft 201.

[0046] (Not shown in the diagram) In another embodiment, a locking element, such as a bolt or clip, is provided inside the bearing to lock the bearing in place. The locking element is inserted into the bearing and does not rotate. After the lower limb protection assembly 2 is rotated to a certain angle (within 30 degrees), the locking element is inserted into the bearing and does not rotate, fixing the lower limb protection assembly 2 within that angle. The locking element is then removed, and the lower limb protection assembly 2 is manually rotated around the base 1 to a suitable angle. After adjustment, the locking element is reinserted to fix the angle of the lower limb protection assembly 2.

[0047] like Figures 4-9As shown, the lower limb protection component 2 comprises: a first sliding member 202, a second sliding member 203, an adjustable airbag 204, an airbag valve 205, a third sliding member 206, a second groove 207, and a third groove 208. The first sliding member 202 and the second sliding member 203 have a semi-circular structure. The first sliding member 202, the second sliding member 203, and the third sliding member 206 are made of lightweight, high-strength materials, such as aluminum alloy or reinforced plastic. The third sliding member 206 is a ball bearing. The third groove 208 is located inside the second sliding member 203 and is circumferentially arranged along the second sliding member 203. The second groove 207 is located outside the first sliding member 202 and is circumferentially arranged along the first sliding member 202.

[0048] One end of the rotating shaft 201 is welded to the lower part of the second sliding member 203, so that the second sliding member 203 rotates in the blind hole 102 on the base 1 through the rotating shaft 201. Both ends of the second sliding member 203 are respectively provided with caps. The third sliding member 206 is installed in the third groove 208, and the caps prevent the third sliding member 206 from detaching from the third groove 208. The first sliding member 202 is installed on the second sliding member 203. The third groove 208 on the second sliding member 203 corresponds to the second groove 207 on the first sliding member 202. Part of the third sliding member 206 is placed in the third groove 208, and part is placed in the second groove 207. Thus, the first sliding member 202 rotates on the second sliding member 203 through the third sliding member 206, that is, it rotates along the circumference of the second sliding member 203.

[0049] An adjusting airbag 204 is bonded to the first sliding member 202. The adjusting airbag 204 has a semi-circular structure and is a small built-in sponge airbag. An airbag valve 205 is provided on the air inlet of the adjusting airbag 204. The airbag valve 205 is a tire valve used to adjust the inflation or deflation of gas or liquid in the airbag 204 and to maintain and detect the internal pressure.

[0050] In usage state 1, during medical rehabilitation, this device can be used to immobilize and protect the lower limbs for patients with lower limb injuries or postoperative recovery. The lower limb protection components 2 on the base 1 consist of multiple sets. First, the position of the lower limb protection components 2 is adjusted according to the size of the patient's lower limb, ensuring the internal space of the components matches the patient's lower limb. Multiple lower limb protection components 2 are then placed inside the components, with the heel suspended. Inflation is achieved by adjusting the airbag valve 205, causing the adjustable airbag 204 to fit tightly against the lower limb, providing a stable immobilization effect. Simultaneously, the angle of the lower limb protection components 2 can be adjusted according to the needs of rehabilitation training, assisting the patient in performing appropriate exercise training.

[0051] Angle Adjustment: When the angle of the lower limb protective component 2 needs to be adjusted, the user can remove the locking piece on the bearing and then manually rotate the lower limb protective component 2 to make it rotate around the pivot 201 to a suitable angle. To facilitate simultaneous angle adjustment and fixation of multiple lower limb protective components 2, multiple lower limb protective components 2 are in contact with each other. When rotating the outermost lower limb protective component 2, the other lower limb protective components 2 can be pushed to rotate synchronously. After adjustment, the locking piece is used to restrict the bearings corresponding to the two outermost lower limb protective components 2. Size Adjustment: Airbag adjustment is achieved by inflating or deflating the adjustment airbag 204 through the airbag valve 205. When inflating, an air pump or manual inflation device is used to inflate the airbag 204 through the airbag valve 205, causing the airbag 204 to expand and fit tightly against the lower limb, providing fixation and cushioning. When deflating, the deflation switch of the airbag valve 205 is opened to release the gas in the adjustment airbag 204, causing the adjustment airbag 204 to contract, making it convenient for the user to put on or take off the device.

[0052] Usage State 2: In medical rehabilitation, this device can be used to immobilize and protect the lower limbs for patients with lower limb injuries or postoperative recovery. First, the airbag is adjusted according to the patient's lower limb size by inflating the adjustable airbag 204 through the airbag valve 205. During inflation, an air pump or manual inflation device is used to inflate the airbag 204 through the airbag valve 205, causing the airbag 204 to expand and fit snugly against the lower limb, providing immobilization and cushioning, with the heel suspended in the air.

[0053] like Figures 1-4 As shown, when the patient moves their upper body, their lower limbs move slightly to the left or right (within 30 degrees). The angle of the lower limb protection component 2 rotates left and right (within 30 degrees) with the amplitude of the lower limb movement. At the same time, the airbag 204 and the first sliding member 202 are adjusted to cooperate with the lower limb to rotate within the second sliding member 203 (within 30 degrees) to avoid injury to the lower limb. The base 1 remains stationary.

[0054] When not in use, open the deflation switch of the airbag valve 205 to release the gas in the regulating airbag 204, causing the regulating airbag 204 to contract and move away from the lower limbs, making it convenient for the user to put on or take off the device.

[0055] Maintenance and upkeep of the device: Regularly inspect the connection points between the base 1 and the lower limb protection assembly 2 to ensure that components such as the rotating shaft 201 are not loose or damaged. When cleaning the device, use a soft cloth to wipe it, avoiding the use of corrosive cleaning agents. For the adjusting airbag 204, gently wipe it with clean water to ensure that its surface is clean and free of dirt. Regularly check the sliding performance of the sliding parts; if there is any jamming, apply a small amount of lubricant for lubrication. Check the sealing performance of the airbag valve 205 to ensure that the adjusting airbag 204 does not leak after inflation. If the airbag valve 205 is found to be damaged, replace it promptly.
