Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an adjustable Braun frame. Background Art

[0002] The Brownian frame is a commonly used medical auxiliary device in orthopedics, primarily used for traction. Using the Brownian frame pulleys, bone or skin traction is performed to reduce fractures and dislocations, maintain position after reduction, correct joint deformities, and relieve muscle spasms and pain.

[0003] Chinese utility model CN215192693U discloses a Brownian frame traction bag, comprising a base sleeve for fitting over the Brownian frame. The top surface of the cushioning layer on the base sleeve is detachably connected to a heel pad and a popliteal pad. This reduces the workload of medical staff, avoids the danger of cutting gauze, and improves patient comfort. However, during use, there are two problems:

[0004] 1. The affected limb is prone to side-to-side movement, affecting the traction effect. During traction, the foot should be kept in a neutral position, and the traction axis should be fixed. The affected limb can perform rehabilitation exercises such as toe wiggling along the traction axis, but should not sway side to side, as this will affect the effectiveness of traction. The heel pad of this utility model fails to stabilize the affected limb, allowing it to easily move side to side or even slip off the sheath, making it difficult to ensure effective traction.

[0005] 2. The thigh support has poor support effect. The thigh support of this utility model cannot be adjusted in length, resulting in poor support effect for the thigh. The weight of the thigh needs to be shared by the calf, which can easily lead to calf pressure sores and nerve compression. Summary of the Invention

[0006] The utility model provides an adjustable Braun's frame, aiming to solve the problems of the existing Braun's frame in that the affected limb is easy to move left and right and the supporting effect on the thigh is poor.

[0007] In order to achieve the above-mentioned purpose, the technical ideas adopted by the present invention to solve the technical problems are as follows:

[0008] An adjustable Brown frame is designed, in which ankle fixing parts are set on the upper surface of the frame to prevent the ankles from swinging left and right; the length of the thigh support is designed to be adjustable, and the support effect on the thigh is enhanced by combining it with a sheath.

[0009] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention to solve the technical problem is:

[0010] An adjustable Brown frame comprises a frame body and an ankle fixing piece for preventing the ankle from moving left and right; the ankle fixing piece is connected to the upper surface of the frame body near the rear end and can slide along the length direction of the frame body.

[0011] Furthermore, the ankle fixing member includes a supporting plate, a first fixing plate, a second fixing plate and an ankle pad;

[0012] The ankle pad is located between the first fixing plate and the second fixing plate; the first fixing plate and the second fixing plate are movably connected to the supporting plate.

[0013] Furthermore, a slide groove is provided on the support plate; an L-shaped connecting piece is connected to the outer sides of the first fixing piece and the second fixing piece;

[0014] The L-shaped connecting piece is slidably connected to the supporting plate via a bolt passing through the sliding groove.

[0015] Furthermore, the rear ends of the first fixing plate and the second fixing plate are connected with fixing clips; the fixing clips can adjust the positions of the first fixing plate and the second fixing plate on the supporting plate.

[0016] Furthermore, the upper surface of the support plate is provided with scale lines for assisting the neutral position of the ankle fastener.

[0017] Furthermore, the inner side surfaces of the first fixing plate and the second fixing plate are both arc-shaped structures.

[0018] Furthermore, the first fixing plate and the second fixing plate are both provided with air holes communicating with each other on the left and right sides.

[0019] Furthermore, the frame includes a calf support and a thigh support with adjustable length.

[0020] Furthermore, the thigh bracket includes a movable rod and a fixed rod sleeved on the movable rod.

[0021] The beneficial effects of the present invention are as follows: compared with the prior art, the improvement of the present invention is that:

[0022] 1. An ankle fixator is installed on the upper surface of the frame to prevent the ankle from moving left or right. The ankle fixator can be adjusted along the length of the frame, suitable for fixing patients of different heights. The width between the first and second fixing plates is adjustable, and with the help of scale lines, ankles of different thicknesses can be fixed on the center line of the support plate, keeping the foot in a neutral position and the traction axis fixed, ensuring the effectiveness of traction and promoting the patient's early recovery.

[0023] 2. By designing the length of the thigh support to be adjustable and using it with a sheath, the thigh support can better fit the curve of the patient's thigh, making it suitable for patients of different body shapes, providing better support and improving the patient's comfort. It avoids the pressure of the thigh weight on the affected calf, effectively preventing pressure sores and compression of the calf nerves, and is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS
