骶尾区

两种平卧承托位头枕区、肩胛区及骶尾区界面压力比较，均有统计学意义（均P<0.05）。

In terms of interface pressures of occipital , scapular , and sacrococcygeal region of patients , there were statistical significance between the two backlying support ⅰ and ⅱ positions ( P < 0.05 ) .

[结果]测得的压力均集中在头枕区、肩胛区和骶尾区，且自动交替承托时，压力点有明显移动，压力值改变，压力值改变最大达10.87kPa；

Result : The detected pressures of patients were centralized on occipital , scapular , and sacrococcygeal region . Moreover , pressure point of patients moved obviously as the support points changed automatically , and pressure value was also changed which reached 10.87 kPa .
