摘要

本實驗以豬為實驗對象，以外施壓力方式，分別以空氣壓縮機輸出500-800mmHg傳送至豬隻股骨外轉子，持續施歷3-6.5小時，後隔4至7天，取下受壓部位標本行顯微觀察。發現受壓600 mmHg5小時以上，允肉層均有明顯病理變化，但皮膚均未發生病變。同時並測量介面壓力，以確知傳送至豬隻體表的壓力，發現約為輸出壓力之60-70%。受壓下方之內部組織壓力則為介面壓力，以確知傳送至豬隻體表的壓力，發現約輸出壓力之60-70%。受壓下方之內部組織壓力則為面壓力之35-50%，即傳入組織之壓力可達100 mmHg以上。

An experimental model was designed to produce pressure sores over the greater femoral trochanter of mormal swines. The pressure was applied under continuous monitor throughout the experiment and kept be-tween 500 to 800 mmHg for 3 to 6.5 hours. Examination of the pressure site at 5 to 7 interval revealed severe muscle damage and intact overlying skin post 600mmHg for more than 5 hours. The interface and underlying tissue pressures were detected at the same time to reveal the pressure transmission. Only 60-70% of output pressure was preserved over interface, and 35-50% was transferred into the underlying tissue, which still was larger than 100 mmHg.
