Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a modified postoperative bandage for minimally invasive breast surgery. Background Technology

[0002] In the recovery process after breast surgery, bandages serve as an important auxiliary tool, and their performance directly affects the patient's wound healing and comfort. Currently, most postoperative breast surgery bandages on the market are made of traditional cotton or synthetic fiber materials, which presents many technical problems that urgently need to be solved.

[0003] From a material performance perspective, while ordinary cotton bandages possess some moisture absorption, their breathability significantly decreases after absorbing moisture, leading to a stuffy and damp environment that hinders wound healing. Synthetic fiber bandages, due to their unique composition, are prone to triggering skin allergic reactions; clinical data shows an allergy rate as high as 20%, causing additional suffering for patients. Regarding pressure adjustment, existing bandages rely on manual adjustments by medical staff based on experience, making precise pressure application difficult and often resulting in significant pressure deviations. This imprecise pressure control can lead to hematoma formation or local circulatory disturbances, severely impacting postoperative recovery. Furthermore, traditional bandages generally use Velcro as the sole fixation method, which can shift during clinical use, requiring frequent re-bandaging. This not only increases the workload for medical staff but may also affect wound stability due to repeated manipulations. More importantly, existing bandages lack real-time wound pressure monitoring capabilities, failing to provide accurate data support for medical staff, resulting in a lack of precision in medical interventions and an inability to meet the refined postoperative care needs of modern breast surgery.
