Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, and in particular relates to a pressure relief patch. Background Technology
[0002] Pressure injuries are localized injuries to the skin, muscles, and subcutaneous tissues caused by pressure, shear force, or friction, often occurring at bony prominences. Pressure injuries are a common problem in rehabilitation and nursing care. Therefore, preventing pressure injuries is of paramount importance in the nursing care of patients who are bedridden for extended periods. Pressure-relieving patches are the most basic and commonly used items for preventing pressure injuries in clinical practice. Traditional pressure-relieving patches are disposable consumables; once removed, they are difficult to securely maintain, increasing costs for patients and being time-consuming and labor-intensive.
[0003] Traditional pressure-relieving patches have a tight, secure fit, effectively reducing pressure on the skin. However, once removed, they cannot be re-adheded tightly. Other adhesive-backed patches are less secure and easily fall off for patients who move around in bed, thus failing to protect the skin. Traditional pressure-relieving patches also prevent direct observation of skin conditions over each shift. For patients who maintain a single supine position for extended periods, changes in local skin conditions are not visible, and if pressure ulcers develop, it's impossible to pinpoint the specific shift in which they occurred.
[0004] Therefore, a stress-relieving patch needs to be designed to solve the above problems. Utility Model Content
