Description

Technical Field

[0001] The utility model relates to the technical field of medical protection, and more specifically, to a protection device for relieving contracture of burn scars. Background Art

[0002] After burn surgery, the burn scar will contract (shrink) as the burn heals. When people move their limbs, the skin will become varicose. If the burn site is not fixed, the skin will pull the burn scar when it is varicose, causing secondary damage to the patient's burn site. Therefore, a protective device is needed to relieve the contracture of the burn scar. The existing related devices are not convenient for limiting the range of limb movement of the user. When the user's limb movement range is large, the joint skin will continue to be varicose, and the skin in contact with the fixed structure may be separated from the fixed structure, so that the continuously varicose skin will pull the burn scar, causing secondary damage to the patient's burn site. To solve the above problems, we have launched the following device. Utility Model Content
