摘要：

背景：高压总是集中在骨突出部位，坐垫应能均匀分布压力，设计一种有效减压的坐垫对压疮预防有重要的作用。
目的：比较几种不同部位防压疮硅胶复合垫与人体接触的压力分布，研究减小界面压力的坐垫形式。
方法：将设计的海绵轮廓垫分为复合硅胶垫和单纯海绵垫两种，复合硅胶垫又分为整个坐面复合硅胶垫，臀部区域复合硅胶垫，坐骨区域复合硅胶垫。用X-sensor压力系统测量4种坐垫压力参数(最大压力，平均压力，压力标准差，坐骨区域压力，骶骨区域压力，大转子区域压力)和面积参数(总体接触面积，高压接触面积，低压接触面积，中压接触面积及高压百分比，中压百分比和低压百分比)。
结果与结论：与单纯海绵垫比较，复合硅胶垫有较小的压力值和高压接触面积及其占总体接触面积的百分比。与整个坐面复合硅胶垫比较，臀部区域复合硅胶垫有较小的压力值和高压接触面积及其占总体接触面积的百分比。与其他3种坐垫比较，坐骨区域复合硅胶垫有最小的压力参数值和高压接触面积及其占总体接触面积的百分比，坐骨区域压力值显著减小(P < 0.05)。表明在海绵轮廓垫上复合硅胶能起到减小界面压力的作用，硅胶垫的复合位置对界面压力值有显著影响。

Abstract:

BACKGROUND: High pressure is always focused on bony prominence, and cushion can evenly distribute seat pressure. Therefore, it is important for pressure ulcer prevention to design an effective decompression cushion.
OBJECTIVE: To compare the pressure distribution of body-cushion interface contacted with anti-pressure sore composite silicone cushions at different positions, and to study the cushion form which can effectively decrease the interface pressure.
METHODS: The foam contour cushions were divided into the compound silicon cushions and pure foam cushions. According the size of the interface area, the compound silicon cushions were divided into full surface, below buttock and ischial tuberosity compound silicon cushions. Pressure parameters (maximum pressure, mean pressure, pressure standard deviation, ischial tuberosity pressure, sacral pressure, great trochanter pressure) and area parameters (overall contact area, high pressure contact area, middle pressure contact area, low pressure contact area and high pressure percentage, middle pressure percentage and low pressure percentage) of the four kinds of cushions on body-cushion interface were measured by X-sensor pressure system.
RESULTS AND CONCLUSION: Compared with pure foam cushions, composite silicon cushions showed smaller pressure value, high pressure area and high pressure percentage. Besides, compared with the full surface composite silicon cushions, the below buttock composite silicon cushions had smaller pressure value, high pressure area and high pressure percentage. While ischial tuberosity compound silicon cushions exhibited the smallest pressure parameters, high pressure area and high pressure percentage compared with the other three kinds of cushions, in addition, the pressure value of ischial tuberosity area was decreased significantly (P < 0.05). These findings suggest that the composite silicon of foam contour cushions can reduce the interface pressure, and the composite positions of silicon cushions have a significant effect on the interface pressure value.
