Description

A lower limb leg raising device

technical field

The utility model relates to a leg raising device for lower limbs, which belongs to the field of leg raising devices.

Background technique

When the human foot or leg is injured or sick, in order to relieve the swelling of the affected limb and facilitate recovery, it is often necessary to raise the affected limb.

The existing nursing method is to apply quilts, clothes or ordinary pillows under the affected limbs. This method has the following disadvantages: (1) The affected limbs are easy to slip and cannot guarantee continuous elevation; (2) The abduction angle of the affected limbs cannot be adjusted. (3) The height of the affected limb is not fixed, the support surface is uneven, and the comfort is poor; (4) The correct guidance and fixation of the feet cannot be formed, and the feet or legs are injured or The recovery period of the disease is relatively long, which can easily lead to foot drop complications and foot pressure sores.

Contents of the invention

In order to solve the above-mentioned defects in the prior art, the utility model provides a lower limb leg raising device.

In order to solve the problems of the technologies described above, the technical scheme adopted in the present invention is as follows:

A leg raising device for lower limbs, comprising a triangular pillow and a leg support device;

The leg support device comprises a leg support block, a foot support device and a connecting device;

The leg support block includes a starting section and a supporting section; the starting section is a slope structure with an inclination angle of 20-30°; the supporting section is a plane structure with a height of 7-15cm; the highest point of the starting section is seamlessly connected with the supporting section ; The side of the leg support block is a right-angled trapezoidal structure; the upper surface of the initial section is provided with a first groove, and the upper surface of the support section is provided with a second groove, and the first groove and the second groove are in the length direction docking and smooth transition, the length directions of the first groove and the second groove are consistent with the direction from the starting section to the supporting section;

The foot support device includes a long plank and a shoe sole, left and right vamps are arranged on both sides of the working surface of the sole in the length direction, and straps are arranged on the left and right vamps; the long plank is fixed on the sole. At the bottom of the working surface, the length direction of the long board and the length direction of the sole are perpendicular to each other;

The long plank of the foot support device is movably connected to the upper surface of the support section of the leg support block through the connecting device, the sole is located directly above the second groove, the working surface of the sole points to the initial section of the leg support block, and the sole The working surface is perpendicular to the length direction of the leg support block, and the length direction of the sole is perpendicular to the upper surface of the leg support block;

One corner of the triangular pillow is defined as the abduction angle, and the two sides forming the abduction angle are respectively defined as the fit side and the connection side, wherein the connection side is movably connected to the side of the leg support block.

The length direction of the support segment is consistent with the length of the leg support block.

Preferably, the connecting ring includes a soft belt, one end of the soft belt is provided with a belt buckle, and the other end is detachably connected to the belt buckle. Similar to the structure of a belt, the structure is simple and easy to operate, and the cost is low.

As another solution of the present application, the connecting device is a connecting block, the bottom of the connecting block is provided with inserting strips, the upper surface of the supporting section is provided with slots that match the inserting strips, and the inserting strips of the connecting block are inserted into the supporting section. inside the slot.

Preferably, the upper surface of the support section is provided with more than two mutually parallel slots along the length direction of the support section, which are matched with the inserts, so that it can be suitable for people with different leg lengths.

In order to improve the comfort in use, a fabric layer is wrapped around the leg support block; an elastic layer is arranged between the fabric layer and the leg support block.

The elastic layer can be a sponge layer or a memory foam layer, etc.

For the convenience of use, the connecting edge of the triangular pillow is connected to the side of the leg support block through Velcro or a snap button. More preferably, it is connected by snap buttons.

Preferably, the abduction angle of the triangular pillow is 20°; the cross section of the leg support block is rectangular. This helps the patient's affected limb to form a neutral position of 20° abduction.

In order to further ensure the accuracy of the abduction angle of the affected limb, the triangular pillow is in the shape of a right triangle, the fitting side of the triangular pillow is a right angle side, and the connecting side is a hypotenuse.

When in use, the abduction angle of the triangular pillow points to the human body. Preferably, the bottom of the hypotenuse of the triangular pillow is movably connected to the side of the leg and foot support device. The bottom of the hypotenuse is the end of the hypotenuse away from the abduction angle.

Preferably, the first groove and the second groove have the same shape and the same depth, and both are circular arc grooves. This further ensures the convenience of use and the simplicity of manufacture.

The technology not mentioned in the utility model all refers to prior art.
