Description

Technical Field

[0001] The present invention relates to the technical field of orthopedic nursing, and in particular to an orthopedic nursing joint limiting device. Background Art

[0002] In the field of ankle orthopedic care, it is very necessary to properly limit the ankle joint during injury or postoperative recovery. Limiting the ankle not only helps stabilize the joint and reduce the risk of further injury, but also promotes tissue healing and provides a good recovery environment.

[0003] At present, the external part of the ankle joint is mainly limited by a specific strap or bracket structure. This brace is mainly composed of hard plastic and flexible fabric materials. Although it has good support and breathability, its thermal insulation performance is relatively poor. In a cold environment, the patient's ankle joint is easily invaded by cold air, resulting in poor local blood circulation, affecting the speed of wound healing, and may even cause complications such as joint stiffness and pain. There are also braces with a fully wrapped design, but this brace is relatively closed. Although it improves the thermal insulation effect to a certain extent, it has poor breathability, poor internal air circulation, and sweat cannot evaporate in time, which makes it easy to get stuffy feet.
