Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a wearable fixation device for preventing lower extremity venous thrombosis. Background Technology

[0002] In the medical field, patients who are bedridden for a long time, recovering from surgery, or suffering from certain diseases have a significantly increased risk of lower extremity deep vein thrombosis. Once a thrombus forms, it can not only cause swelling and pain in the lower extremities, but in severe cases, it can also easily lead to life-threatening complications such as pulmonary embolism. Therefore, effective prevention of lower extremity deep vein thrombosis is crucial for the patient's recovery and health.

[0003] Existing fixation devices for preventing lower extremity deep vein thrombosis are not very effective in maintaining proper leg and foot posture, thus hindering blood circulation. Furthermore, the materials used are often uncomfortable, and prolonged wear can cause skin allergies, itching, and other discomforts, reducing patient compliance. Additionally, they are not easily adjustable for patients with different leg shapes and sizes, limiting their applicability. Therefore, we have developed a wearable fixation device for preventing lower extremity deep vein thrombosis. Utility Model Content

[0004] The main purpose of this invention is to provide a wearable fixation device for preventing lower extremity venous thrombosis, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A wearable fixation device for preventing lower extremity deep vein thrombosis includes mounting plates. Two mounting plates are provided. Bearings are inserted and fixedly installed on the lower inner side of each of the two mounting plates. Movable rods are fixedly installed inside each of the two bearings. Anti-dislodgement blocks are fixedly connected to the outer side of each of the two movable rods. A leg fixation component is fixedly connected to the upper part of the two mounting plates together. A foot fixation component is fixedly connected to the two movable rods together.

[0007] The leg fixing assembly includes a breathable sponge inner layer, an aluminum alloy middle layer fixedly connected to the outer surface of the breathable sponge inner layer, a Lycra outer layer fixedly connected to the outer surface of the aluminum alloy middle layer, a connecting assembly fixedly connected to the outer surface of the Lycra outer layer, and the lower part of the Lycra outer layer fixedly connected between two mounting plates.

[0008] Preferably, the breathable sponge inner layer, the aluminum alloy middle layer, and the Lycra outer layer are all circular and have through openings on the front of their outer surfaces.

[0009] By adopting the above technical solution, the breathable sponge inner layer, the aluminum alloy middle layer, and the Lycra outer layer all have openings on the front surface that allow for both internal and external penetration. When wearing the device, users do not need to laboriously put their entire leg into the fixation device. They can simply put their leg in through the opening and then fix it with the connecting components. This greatly saves time and effort in wearing the device, and significantly improves the convenience of use, especially for patients with mobility impairments.

[0010] Preferably, the connecting component includes a fixing block and a first hook and loop fastener connecting block, and three fixing blocks and three first hook and loop fastener connecting blocks are provided. The right end of each of the three fixing blocks is fixedly connected to a first hook and loop fastener strap, and the rear ends of the three fixing blocks and the rear ends of the three first hook and loop fastener connecting blocks are fixedly connected to the outer surface of the Lycra outer layer.

[0011] By adopting the above technical solution: the connecting component is equipped with three fixing blocks and corresponding first Velcro connecting blocks, and each fixing block is connected with a first Velcro fixing strap. Users can adjust the pasting position of the three Velcro fixing straps according to their own leg circumference, comfort and the force requirements of different parts of the leg, so as to adjust the tightness of the fastener, ensure that the fastener fits tightly to different leg shapes, and improve the comfort and stability of wearing.

[0012] Preferably, the three fixing blocks and the three first hook and loop fasteners are distributed at equal intervals in pairs, and the rear ends of the three first hook and loop fasteners are respectively attached to the front ends of the corresponding three first hook and loop fasteners.

[0013] By adopting the above technical solution, this equidistant distribution design allows the fixation device to better adapt to leg shapes of different thicknesses and sizes. Whether it is a slender calf or a thicker thigh, users can adjust the first Velcro fastening strap at different positions to make the fixation device fit the leg contour tightly, achieving a personalized fixation effect and expanding the range of people to whom the fixation device is applicable.

[0014] Preferably, the foot fixation assembly includes a hard plastic foot support plate, with two second Velcro fastening straps fixedly connected to the left end of the hard plastic foot support plate, and two second Velcro connecting blocks fixedly connected to the right end of the hard plastic foot support plate. The left and right ends of the hard plastic foot support plate are respectively fixedly connected to the inner sides of two corresponding movable rods.

[0015] By adopting the above technical solution, the hard plastic foot support plate can provide solid and stable support for the sole of the foot, maintain the normal shape of the arch of the foot, avoid affecting blood circulation due to prolonged pressure on the plantar veins, and effectively reduce the risk of lower extremity venous thrombosis.

[0016] Preferably, the positions of the two second hook and loop fasteners and the positions of the two second hook and loop connecting blocks correspond to each other and are glued together.

[0017] By adopting the above technical solution, the two second Velcro fastening straps are aligned with and attached to the corresponding second Velcro connecting blocks, providing a strong and uniform fixing force to firmly fix the foot to the hard plastic foot support plate.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In this utility model, the leg fixation component and foot fixation component can stably fix the leg and foot, maintain normal physiological posture, promote blood circulation, and effectively prevent thrombosis. The leg fixation component adopts a three-layer structure of breathable sponge inner layer, aluminum alloy middle layer and Lycra outer layer. The breathable sponge inner layer is close to the skin, soft and comfortable, and can avoid skin allergies and discomfort. The aluminum alloy middle layer provides solid support to ensure the correct leg posture. The Lycra outer layer has good elasticity, so that the fixation device fits tightly without producing an excessively tight feeling of restraint, which greatly improves the patient's wearing comfort and compliance.

[0020] 2. In this utility model, the fixator is provided with two mounting plates, which are connected by bearings and movable rods. Patients can finely adjust the angle between their feet and legs according to their own comfort to meet the needs of different patients in different activity states. At the same time, the first Velcro connecting block and the second Velcro fixing strap in the connecting component and the foot fixation component are provided to facilitate the adjustment of the tightness of the fixator, which can adapt to patients with different leg shapes and sizes, significantly improving the applicability and flexibility of the product.
