[0002] Pressure injury is caused by long-term compression of local tissues in the body, which hinders blood circulation and cannot properly provide the nutrients needed by the skin and subcutaneous tissues, causing the local tissues to lose their normal functions and form ulcers and necrosis. In order to prevent pressure injuries to the affected parts of some critically ill patients, the affected parts need to be suspended in the air to prevent them from contacting other substances, thereby facilitating the healing and recovery of the affected parts. For this reason, it is necessary to provide auxiliary treatment operations for critically ill patients through pressure injury prevention equipment.
