Abstract
The invention relates to a rehabilitation therapy and movement protection tool based on a shape memory polymer. The rehabilitation therapy and movement protection tool comprises wrist bands, kneecaps, elbow pads, shoulder pads, a neck guard and the like, wherein the wrist bands, the kneecaps and the elbow pads are used for movement protection, and the shoulder pads, the neck guard and the like are used for rehabilitation therapy. The rehabilitation therapy and movement protection tool includes a tubular body which is opened or closed, and the tubular body is made of a shape memory polymer material which is elastic or rigid at a normal temperature. The pre-deformation temperature of the tubular body is 30-80 DEG C, and the tubular body can be in the deformed shape matched with the shapes of the wearing positions of a human body at the pre-deformation temperature and can keep the pre-deformed shape after being cooled. According to the rehabilitation therapy and movement protection tool based on the shape memory polymer, the body of the therapy and protection tool is made of the shape memory polymer material, and the wearing positions can be limited and removed through the change between the pre-deformation shape and the recovery shape. Due to the fact that there is no need for the pre-deformation shape in the limited state to consider the follow-up disengaging means, the pre-deformed shape can be completely matched with the wearing positions, and therefore the wearing comfort and convenience are improved.
