Description

Medical trough lower extremity anti-rotation brace

technical field

The utility model relates to a medical groove type lower limb anti-rotation support.

Background technique

At present, with the accelerated pace of modern life, the increase of work intensity, and the aging of the population, lower limb fractures are caused, and the number of elderly patients with hip fractures is increasing. The number of users receiving lower extremity surgery to treat diseases is also growing rapidly due to the ever-improving medical technology. Under normal conditions, the lower limbs are in a state of external rotation when a person is in bed. Therefore, it is necessary to prevent the external rotation of the lower limbs from causing damage to the common peroneal nerve and dislocation of the hip joint after surgery. For example, for elderly hip fractures, the preoperative waiting time is 24-48 hours. In the past, the preoperative waiting time was 3-7 days, and bone traction and braking were required. At present, the preoperative waiting time is shortened, and bone traction is not required. However, the waiting time The affected limb is in a state of external rotation, and it is easy to compress the common peroneal nerve, resulting in damage to the nerve. Due to the different degrees of nerve damage in the ankle joint and toes of the affected limb, foot drop occurs, and the toes cannot do back extension. After lower limb fractures, especially anesthesia is Anesthesia, epidural anesthesia or combined spinal-epidural anesthesia is required. There is a 6-hour anesthesia recovery period. During this period, the sensory and motor of the lower extremities are all poor, and the lower extremity is operated again. Nerve damage, but the existing related equipment is relatively simple, only using bedding, pillows and other barriers, which is inconvenient for patients to use, not comfortable, and is not conducive to clinical application, as well as the protection of the affected limb and postoperative recovery.

Utility model content

The utility model aims to provide a medical groove type lower limb anti-rotation support, which is convenient and comfortable to use, can better fix and protect the lower limb, can be used as a temporary brake, and can also prevent the dislocation of the hip joint.

The top surface is flat.

The above structure is beneficial to fix the lower limbs of the user according to the size of the user's legs, and at the same time, the fixing belt is located in the micro-groove to be at the same level as the upper surface of the bottom plate, so as to ensure the comfort of the user during use.

Furthermore, in the medical grooved lower extremity anti-rotation brace of the present invention, preferably, a plurality of the microgrooves are formed on the upper surface of the bottom plate.

Furthermore, in the medical trough type lower limb anti-rotation brace of the present invention, preferably the upper surface of the bottom plate, the one side wall, the other side wall and the inner surface of the back plate are the same/different. of flexible material.

The design of the flexible material makes it more comfortable for the user to use.

Furthermore, in the medical grooved lower limb anti-rotation brace of the present invention, preferably, the bottom plate, the one side wall, the other side wall and the back plate are integrally formed and are all made of sponge.

This can play a supporting role and bring a more comfortable experience to the user.

Furthermore, in the medical grooved lower limb anti-rotation brace of the present invention, the length of the bottom plate, the one side wall and the other side wall is preferably 50 cm, the width of the bottom plate, the length of the back plate, and the The height of the one side wall and the other side wall is 26 cm, the distance between the inner surfaces of the one side wall and the other side wall is 12 cm, and the thickness of the bottom plate is 6 cm.

Detailed ways

Hereinafter, referring to the accompanying drawings, the medical trough type lower limb anti-rotation support M according to the embodiment of the present invention will be described.

Example 1

1 and 2, the medical trough-type lower limb anti-rotation support M includes: a rectangular bottom plate 1, the length of which exceeds the human knee; a side wall 2, which is detachably fixed on one side of the bottom plate 1 in the length direction, 1 extends along the entire length direction; another side wall 3, which is detachably fixed on the other side in the length direction of the bottom plate 1, extends along the entire length direction of the bottom plate 1, and has a height below one side wall 2; and a back plate 4 , which is fixed on one side in the width direction of the base plate 1 .

The figures show the use of the right leg. When the left leg is in use, the other side wall 3 can be exchanged with one side wall 2 to keep the one side wall 2 outside the user's left leg.

One side wall 2 is used to protect the external rotation of the lower limb, and the other side wall 3 plays a protective role for the lower limb. By exchanging the positions of one side wall 2 and the other side 3, the medical trough type lower limb anti-rotation support of the present invention can be applied to both the left and right legs, and there is no need to produce a product suitable for the other leg, which further saves the process. and cost. The back plate 4 is beneficial to better protect the lower limbs, especially the feet, from being touched, so as to avoid further injury, and is also beneficial to move more conveniently when needed.

Although not shown in the figure, one side wall 2 and the other side wall 3 can be detachably connected to the bottom plate 1 by means of plugging or screwing.

Again, with reference to Figures 3 and 4, the upper surface of the bottom plate 1 of the medical grooved lower limb anti-rotation brace M is provided with a micro-groove 11, wherein a fixing band 12 is provided, and one end of the fixing band 12 is connected with the bottom plate 1, and the other end has a The connecting piece 121 can be adjustably combined with the fixing structure 21 on one side wall 2 . As shown in FIG. 4 , the upper surface of the portion of the fixing band 12 located on the base plate 1 is flush with the upper surface of the base plate 1 when the fixing belt 12 is not in use and is laid flat.

The dashed line in FIG. 4 shows the fixing strap 12 in the use state. When the size difference between the user's leg L and the medical grooved lower limb anti-rotation support M is large, or in order to obtain a better fixation effect, the connecting piece 121 on the fixing belt 12 and one side wall 2 can be used. The fixing structure 21 is combined with the fixing structure 21 for more effective fixing.

The adoption of the above structure is beneficial to fix the lower limbs of the user according to the size of the user's legs, so that the medical grooved lower limb anti-rotation support M has better applicability, and at the same time the fixing belt 12 is in the micro-groove 11 and the upper surface of the bottom plate. It is located at the same level to ensure the comfort of the user when using it.

Furthermore, a plurality of micro-grooves 11 may be formed on the upper surface of the bottom plate 1 of the medical grooved lower extremity anti-rotation brace M. The plurality of fixing straps 12 in the plurality of micro-grooves 11 can further enhance the fixing effect.

Furthermore, the upper surface of the bottom plate 1 , one side wall 2 , the other side wall 3 and the inner surface of the back plate 4 of the medical grooved lower limb anti-rotation brace M are made of the same/different flexible materials.

The design of the flexible material makes it more comfortable for the user to use.

Example 2

Referring to Fig. 5, the medical trough type lower limb anti-rotation support M includes a rectangular bottom plate 1, and its length is a; , and extends along the entire length direction of the bottom plate 1, with the same height b; The bottom plate 1, the two side walls 2, 3 and the back plate 4 are integrally formed and are all made of sponge. In this way, it can play a supporting role and bring a more comfortable experience to the user.

According to the ergonomic test, the length of the two side walls and the length a of the bottom plate 1 are preferably 50 cm, the width of the bottom plate 1, the length d of the back plate 4, and the height b of the two side walls are 26 cm, and the inner surfaces of the two side walls are 26 cm. The distance d is 12 cm, and the thickness e of the bottom plate is 6 cm.
