In this embodiment, the deformation layer is preferably an air bag, which is moderately soft and hard, has a good fit and fixation effect after binding, and allows a certain degree of mobility in the waist and abdomen to avoid thrombosis or numbness caused by long-term binding. Preferably, the deformation layer gradually thickens from the end close to the first hard plate to the end away from the first hard plate, so that it can better fit the waist and abdomen of the lying patient. In some embodiments, the deformation layer 6 can be a silicone pad or a rubber pad, etc., not limited to this embodiment.
