层流手术室用防静电手术衣面料设计及性能测试

Design and Performance Test of Anti-static Operating Gown Used in Laminar Flow Operating Room

对层流手术室内使用的防静电手术衣特性及结构进行分析,手术衣常采用3层复合结构,表层为经编织物、中间层为亲水性PES(聚醚砜)微孔膜、内层为平纹织物。当采用同一种防静电丝面料时,探讨3层复合防静电手术衣面料与单层防静电面料的防静电性能指标差异,并对手术衣的防静电性能进行测试。结果表明,3层复合面料的电荷面密度和手术衣的防静电性能均符合标准要求,并对层流手术室防静电手术衣的选择提出建议。

The paper analyzes the characteristics and structures of anti-static operating gown used in laminar flow operating room, and designs a three-layer composite structure with warp knitted fabric as the surface, hy- drophilic PES mieroporous membrane as the middle and plain woven as the internal. In addition, it investigates the anti-static performance differences between the three layer composite anti-static operating gown and one layer anti- static fabric by use the same antistatic wire distribution fabric, and tests the anti-static property of operating gown. The results show that the electric charge density of three-layer composite fabric and anti-static property of operating gown can meet the national standards, which give the recommendations to choose anti-static operating gown for laminar flow operating room.
