Description

Technical Field

[0001] This utility model relates to the field of joint brace devices, specifically an inflatable knee brace. Background Technology

[0002] The knee joint is the most complex and largest joint in the body structure, subjected to the strongest leverage force, and plays a crucial role in bearing weight and transmitting loads. The knee joint primarily performs flexion and extension movements, with rotational movements in the flexed position, and a small range of passive inversion and valgus movements. In essence, the knee joint's function is to adjust the distance between the pelvis and the foot to accomplish various activities. In activities such as running, moving in place, and lifting and landing, its main functions are maintaining lower limb length, absorbing shock, and transmitting weight. In forward-moving activities, the knee joint primarily provides forward propulsion. Knee braces are essential assistive fixation medical tools that all knee injury patients must wear after surgery, playing a vital role in postoperative recovery. Currently available knee braces have a basically similar structure, using Velcro straps to secure the brace, which is connected by a rotating plate for angle adjustment according to knee recovery. This type of brace relies solely on the friction of the straps for fixation. However, the human leg tapers downwards, making the brace prone to slipping off due to a lack of vertical support. Overly tight straps can cause discomfort for the patient. Utility Model Content

[0003] The purpose of this invention is to provide an inflatable knee brace to solve the problem that the type of brace mentioned in the background art relies solely on the friction of binding for fixation. Since the shape of the human leg is tapering downwards, the brace is prone to falling off due to the lack of vertical support when worn, and overly tight straps can cause discomfort to the patient.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an inflatable knee brace, comprising an upper brace, a lower brace, an inflation component, and an adjustment component;

[0005] Wherein: the bottom of the upper support is provided with a lower support, and the upper support and the lower support are connected by a fixed plate;

[0006] The inflatable assembly includes an inflatable leg sleeve connected to the inner side of the upper and lower supports. The inflatable leg sleeve is an inflatable long strip sleeve that conforms to the shape of the leg. An inflation nozzle is installed on the top outer wall of the inflatable leg sleeve.

[0007] The adjustment assembly includes a connecting rack connected to the top side of the lower support, a support column connected to the bottom side of the upper support, a movable groove opened on one side of the surface of the fixed plate, the connecting rack and the support column both inserted into the movable groove, and a limiting tooth hinged to the surface of the support column, the limiting tooth being inserted into the connecting rack.

[0008] As a preferred embodiment of this utility model, a torsion spring is also provided at the hinge joint between the support column and the limiting tooth.

[0009] As a preferred embodiment of this utility model, an opening is provided on the front side of the inflatable leg sleeve.

[0010] As a preferred embodiment of this utility model: the inflatable leg sleeve, after being inflated, matches the upper and lower supports.

[0011] As a preferred embodiment of this utility model, the inner wall of the inflatable leg sleeve is made of soft fabric.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) An inflatable leg sleeve is connected to the inside of the upper and lower braces. An inflation nozzle is installed on the top outer wall of the inflatable leg sleeve. When the patient uses it, the leg is inserted into the inflatable leg sleeve so that the upper and lower braces are adjusted to the knee joint. At this time, air is inflated into the inflatable leg sleeve through the inflation nozzle, so that the inflatable leg sleeve expands and is fixed to the leg joint. The inflatable leg sleeve is an inflatable long strip sleeve that fits the shape of the leg, so that it is stably worn at the joint. Compared with the method of fixing with magic straps, the inflatable leg sleeve can fit and fix the leg better and avoid slipping.

[0014] (2) Through the provided adjustment components, a connecting rack is connected to the top side of the lower support and a support column is connected to the bottom side of the upper support. The support column and the connecting rack are both inserted into the movable groove opened on the surface of the fixed plate. The support column is hinged with a limiting tooth, which is inserted into the connecting rack. When the upper and lower supports are adjusted at an angle, the limiting tooth on the surface of the support column is adjusted and inserted into the connecting rack, so as to ensure the adjusted angle position. The torsion spring is activated to push the limiting tooth and the connecting rack to form a stable connection. Attached Figure Description
