Description

Technical Field

[0001] This utility model relates to the field of orthotics, specifically to an orthotics for preventing joint deformities of residual limbs. Background Technology

[0002] Orthotics used to prevent joint deformities of the residual limb are generally made of elastic fabric or composite materials containing elastic fibers. Elastic bandages are a simple and common form. They are wrapped around the limb and use their elasticity to generate moderate pressure. This pressure can promote blood circulation in the residual limb and at the same time play a certain role in stabilizing the joint.

[0003] Orthotics for preventing joint deformities in residual limbs are pre-formed sleeve-like structures that conform to the shape of the limb. They primarily control limb swelling by providing uniform pressure and, to some extent, limit the abnormal range of motion of the joints.

[0004] Orthotics used to prevent joint deformities of residual limbs are usually made of materials such as rubber or tightly woven fabrics. The molecular structure of rubber is dense and has almost no pores to allow air to pass through. This restricts the air exchange needed for sweat evaporation. When used in summer, due to the hot weather, sweat accumulates between the skin and the orthotics when the patient wears it, making the skin in a moist environment. This prevents the sweat from evaporating in time, which can easily breed bacteria and fungi and cause skin inflammations such as eczema and rashes.

[0005] Therefore, an orthotic device for preventing joint deformities of the residual limb is proposed to address the above problems. Utility Model Content

[0025] Please see Figure 1-5 This utility model provides a technical solution:

[0026] An orthotic device for preventing joint deformities of residual limbs includes a fixation strap 1 with metal support, a fixing iron piece 2, and a connecting elastic band 3. The fixing iron piece 2 is fixedly connected to the outside of the fixation strap 1. One end of the fixing iron piece 2 passes through one side of the fixation strap 1 and is fixedly connected to one end of the connecting elastic band 3. The connecting elastic band 3 is fixedly connected to a soft orthotic sleeve 4 through the fixing iron piece 2. An adjustment device 5 is fixedly connected to one end of the fixation strap 1, and a ventilation device 6 is installed on the outside of the fixation strap 1. The fixation strap 1 includes a fixation strap body 11, and an installation groove 12 is formed on one side of the fixation strap body 11. 12 is fixedly connected to one side by a hook and loop fastener 13 through sewing. The breathable device 6 includes a moisture-absorbing layer 61. An auxiliary structure 62 is fixedly connected to one side of the moisture-absorbing layer 61 through sewing. A zipper 63 is fixedly connected to the outer side of the moisture-absorbing layer 61. A loop fastener 64 is fixedly connected to the other side of the moisture-absorbing layer 61. A breathable layer 65 is fixedly connected to the inner side of the moisture-absorbing layer 61. A latex layer 66 is fixedly connected to the other side of the breathable layer 65. The breathable layer 65 includes a layer body 651. A first breathable hole 652 and a second breathable hole 653 are opened on the inner side of the layer body 651.

[0027] As a further implementation of the above technical solution: a breathable layer 65 and a latex layer 66 are provided on the inner side of the moisture-absorbing layer 61. The breathable layer 65 and the latex layer 66 are of equal shape and equal thickness. The breathable layer 65 and the latex layer 66 are parallel to each other. The latex layer 66 can cooperate with the breathable layer 65 in the orthodontic appliance to further enhance the overall breathability and play a role in cushioning and shock absorption.

[0028] As a further implementation of the above technical solution: a plurality of second vent holes 653 are provided. The shape of the second vent holes 653 is spiral. The second vent holes 653 are evenly and equidistantly arranged on the inner side of the layer 651. The second vent holes 653 are parallel to each other. The first vent holes 652 and the second vent holes 653 are staggered. The spiral structure of the second vent holes 653 can make the air form a slow spiral flow in the hole, reduce the airflow speed, and reduce skin discomfort caused by the rapid airflow taking away the heat from the skin surface.

[0029] As a further implementation of the above technical solution: two auxiliary structures 62 are provided. The auxiliary structures 62 are symmetrically arranged with the vertical line of one side of the moisture-absorbing layer 61 as the axis. The auxiliary structures 62 are located at both ends of the moisture-absorbing layer 61. The auxiliary structures 62 and the side of the fixing belt body 11 with the installation groove 12 are not on the same horizontal plane, which can effectively assist in the installation and fixing of the moisture-absorbing layer 61.

[0030] As a further implementation of the above technical solution: the installation groove 12 and the moisture-absorbing layer 61 are set with the same shape. The moisture-absorbing layer 61 is installed inside the installation groove 12. The side of the moisture-absorbing layer 61 that is close to the auxiliary structure 62 is on the same horizontal plane as the side of the fixing belt body 11 that has the installation groove 12. This setting can make the overall structure more reasonable, facilitate the installation of the moisture-absorbing layer 61, and quickly absorb the sweat generated on the skin surface.

[0031] As a further implementation of the above technical solution: a number of first vent holes 652 are provided. The vertical cross-section of the first vent holes 652 is trapezoidal. The first vent holes 652 are evenly and equidistantly distributed on the inner side of the layer 651. The first vent holes 652 are parallel to each other. The first vent holes 652 adopt a gradually increasing pore size setting. The pore size of the first vent holes 652 gradually increases, so that the moisture generated when the patient moves can be smoothly discharged through the gradually increasing pore size.

[0032] As a further implementation of the above technical solution: the hook and loop fasteners 13 and the loop fasteners 64 are set to be the same shape as the mounting groove 12, the loop fasteners 64 are installed on one side of the hook and loop fasteners 13, and the hook and loop fasteners 13 and the loop fasteners 64 are parallel to each other, so as to ensure that the ventilation device 6 can be firmly installed on the fixing strap 1 and is easy to disassemble and install.

[0033] Workflow: First, unfold the fixation strap 1 with metal support strips, and place the soft orthotic sleeve 4 onto the residual limb. Then, secure the connecting elastic band 3 to the soft orthotic sleeve 4 using the fixing iron piece 2, ensuring initial fit between the orthosis and the residual limb. Next, tie the fixation strap 1 around the waist using the adjustment device 5, ensuring it fits snugly. Then, adjust the tightness of the fixation strap 1 using the adjustment device 5 at one end. The connecting elastic band 3 can accommodate the movement of the residual limb to a certain extent, while providing a certain elastic tension to help maintain the residual limb. With proper posture, when the patient wears the orthosis, the sweat produced by the residual limb first comes into contact with the moisture-absorbing layer 61. The moisture-absorbing layer 61 absorbs the sweat, storing it through its material properties to prevent sweat buildup between the residual limb and the orthosis, keeping the skin surface relatively dry. Simultaneously, the breathable layer 65 inside the moisture-absorbing layer 61 begins to function. The breathable layer 65 has a first vent 652 and a second vent 653 on its body 651. The first vent 652 allows air exchange between the inside and outside of the orthosis, promoting sweating. The evaporation of liquid, the spiral-shaped second vent 653 and the first vent 652 are staggered, which can increase the air flow path and time in the breathable layer 65, further improving the breathability and helping sweat to evaporate and be discharged faster. The mounting groove 12 is fixedly connected with hook-and-loop fasteners 13 by stitching, and the corresponding side of the breathable device 6 has a loose-sided hook-and-loop fastener 64. The fasteners ensure that the breathable device 6 can be firmly installed on the fixing strap 1, and facilitates disassembly and installation. When it is necessary to clean the breathable device 6 or... When replacing the device, by holding the auxiliary structure 62, the ventilation device 6 is pulled outwards to separate the hook-and-loop fasteners 13 and serrated fasteners 64, allowing the ventilation device 6 to be removed. Then, the ventilation layer 65 and latex layer 66 are taken out through the zipper 63 on the outside of the moisture-absorbing layer 61, and the moisture-absorbing layer 61 is cleaned. This effectively handles sweat produced by the residual limb, keeping the inside of the orthosis dry and breathable, improving the patient's wearing comfort. The latex layer 66 works in conjunction with the ventilation layer 65 in the orthosis to further enhance the overall breathability, while also acting as a cushioning and shock absorber, absorbing the impact of walking on the residual limb and effectively reducing the pressure on the residual limb.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
