Description

Adjustable Knee Brace with Air Cushion

technical field

The utility model relates to the technical field of medical equipment, in particular to an adjustable knee joint brace with an air cushion.

Background technique

The knee joint is one of the most important load-bearing joints in the human body, but the knee joint is relatively superficial, and it is prone to structural damage such as bones, ligaments, and cartilage when it suffers trauma. When carrying out conservative treatment or rehabilitation after surgery, we require patients to keep the knee joint stable to facilitate the recovery of the damaged structure of the patient, but if the knee joint is too fixed, it is easy to cause adhesion of the knee joint, resulting in a decrease in the range of motion of the knee joint in the later stage , seriously affecting the life and work of patients. This requires us to provide a certain range of motion for the knee joint while maintaining the stability of the patient's knee joint to prevent adhesions of the knee joint.

In order to improve the existing technology, people have carried out long-term exploration and proposed various solutions. It generally includes two thigh splints and two calf splints. The two thigh splints are respectively bound on both sides of the thigh, and the two calf splints are respectively bound on both sides of the calf. The upper ends of the upper ends meet each other, and an angle adjustment locking device is arranged between the thigh splint and the calf splint. Although the above solution solves the deficiencies of the prior art to a certain extent, since the legs themselves are large up and down, the two thigh splints and the two calf splints are all fixed on the thigh and the calf by binding Therefore, it will slide down under the action of gravity, resulting in unstable support and affecting the use effect.

Utility model content

The purpose of this utility model is to provide an adjustable knee brace with an air cushion. The technical problem to be solved is that the traditional knee brace can only fix the thigh splint and the calf splint on the thigh and calf respectively. , the joint support angle can be adjusted, however, the thigh splint and the calf splint are tied on both sides of the thigh and calf by bandages or other straps, and it is easy to slide down under the action of gravity, resulting in the joint support formed between the thigh splint and the calf splint The structure and the position of the knee joint form a slight misalignment, which affects the normal use of the knee joint brace.

In order to solve the above technical problems, the utility model provides an adjustable knee brace with an air cushion, which includes a cone-shaped thigh sheath and a calf sheath, both of which are elastic hard Made of high-quality materials, one side of the cone-shaped thigh sheath and calf sheath is provided with an axially penetrating opening, and the thigh sheath and calf sheath can be fixed on the thigh and calf of the human body respectively. On the top, the openings on the thigh sheath and the calf sheath correspond to the front position on the thigh and the calf respectively, the axial ends of the thigh sheath and the calf sheath are provided with straps, and the thigh sheath A number of inflatable and deflated thigh airbags and calf airbags are respectively fixed on the inner side walls of the cover and the calf sheath, each of the thigh airbags and calf airbags has an air nozzle for inflation and deflation, and the air nozzle can Connect an external air pump.

Preferably, both the thigh sheath and the calf sheath are made of elastic hard plastic, both sides of the thigh sheath are fixedly connected with thigh fixing plates, and both sides of the calf sheath are fixedly provided with calf fixing plates. The lower ends of the two thigh fixing plates are fixedly connected with angle adjustment locking devices, and the upper ends of the two lower leg fixing plates are respectively hinged on the two angle adjustment locking devices. The angle between the thigh plates is adjustable and lockable.

Preferably: the inner wall of the thigh sheath and the calf sheath are all provided with a flexible inner lining, and some thigh airbags on the inner wall of the thigh sheath and some calf airbags on the inner wall of the calf sheath are respectively arranged on the In the corresponding flexible inner lining.

Preferably: three elongated thigh airbags are arranged on the inner wall of the thigh sheath, and the two ends of the three elongated thigh airbags correspond to the axial direction of the thigh sheath respectively. At both ends, three strip-shaped thigh airbags are respectively arranged on the inner side wall of the thigh sheath corresponding to the rear side of the thigh and the positions on both sides of the thigh; the inner side wall of the calf sheath is provided with three The elongated calf airbags, the two ends of the three elongated calf airbags respectively correspond to the axial ends of the calf sheath, and the three elongated calf airbags are respectively set The inner side wall of the calf sheath corresponds to the rear side of the calf and the positions on both sides of the calf.

Compared with the prior art, the beneficial effects of the utility model are:

1. By setting a number of thigh airbags and calf airbags on the inside of the thigh sheath and calf sheath respectively, the fluidity of the gas can be used to fill the gap between the thigh sheath and the calf sheath and the thigh and calf, so that the The thigh sheath and the calf sheath can be clamped more stably on the thigh and calf;

2. With the help of the thigh sheath and the calf sheath with openings in the front side of the cone, the elastic opening can be hugged to the thigh and the calf, and the thigh sheath and the calf sheath are made of elastic hard materials Therefore, the thigh sheath and the calf sheath can be radially folded and tightly hugged on the thigh and calf through the straps at both ends, so as to realize tight hugging on the legs of different users and provide rigid support;

3. Adjust the angle adjustment locking device according to the user's situation to adjust the knee joint support angle, and formulate the range of allowable knee joint movement; adjust the thigh airbag and calf airbag, so that the knee joint is in the corresponding varus or valgus position, which is beneficial to the knee joint. Repair of damaged joint structures;

4. For patients with lateral instability of the knee joint, the air pressure of the calf airbags on both sides can be adjusted to fix the calf to the corresponding side, which is convenient to use.

detailed description

The knee joint adjustable brace with air cushion proposed by the utility model will be described in more detail below in conjunction with the accompanying drawings 1-4 and preferred embodiments.

The utility model provides an adjustable knee brace with an air cushion, which includes a cone-shaped thigh sheath 1 and a calf sheath 2, and the thigh sheath 1 and the calf sheath 2 are elastic hard materials One side of said thigh sheath 1 and shank sheath 2 in cone shape is provided with axially penetrating openings (11, 21), said thigh sheath 1 and shank sheath 2 can respectively hold Covered on the thigh and calf of the human body, the openings (11, 21) on the thigh sheath 1 and the calf sheath 2 correspond to the front position on the thigh and the calf respectively, and the thigh sheath 1 and the calf sheath 2 are provided with straps (not shown in the figure) at both ends in the axial direction, and the straps are used to fix and hold the thigh sheath 1 and the calf sheath 2 on the thigh and the calf respectively. A plurality of inflatable and deflated thigh airbags 3 and calf airbags 4 are respectively fixed on the inner side walls of the sheath 1 and the calf sheath 2, and each of the thigh airbags 3 and calf airbags 4 has an air pocket for inflation and deflation.
