Fluid leakage through the glove-protective clothing interface is an area of concern for many health care personnel, including emergency medical service providers, who may wear coveralls to protect themselves from multiple types of hazards. There is currently no established standard test method to specifically evaluate the barrier performance of the glove-protective clothing interface region for any personal protective equipment ensemble.
This study quantifies the fluid leakage at the coverall and glove interface using single and double gloving.
A robotic arm, which can simulate upper extremity movements of health care personnel, was used to test 5 coverall models and an extended examination glove model in single and double glove conditions.
The results show that there was a significant difference in fluid leakage amounts between some of the coverall models and the number of glove layers studied. Findings also highlight that there is a high correlation between basis weight and stiffness of the coverall fabrics and the fluid leakage amounts.
These results underline that coverall constructed from thin and less stiff fabrics can result in lower fluid leakage levels. Also, there was no significant difference in fluid leakage amounts between single and double gloves when tested with each of the coverall models, with the exception of the coveralls with the highest basis weight and stiffness.
液体通过手套-防护服界面的泄漏是许多医护人员关注的一个领域，包括急诊医疗服务提供者，他们可能会穿着防护服以防止多种类型的危害。目前，还没有针对任何个人防护设备组件的手套-防护服界面区域的屏障性能的既定标准测试方法。
本研究使用单层和双层手套来量化防护服和手套接口处的液体泄漏。
一种可以模拟医护人员上肢运动的机械臂被用于在单层和双层手套条件下测试 5 种防护服模型和一种加长检验手套模型。
结果表明，在一些防护服模型和所研究的手套层数之间，液体泄漏量存在显著差异。研究结果还强调，防护服织物的基重和刚性与液体泄漏量之间存在高度相关性。
这些结果表明，由薄而刚性较小的织物制成的防护服可导致较低的液体泄漏水平。而且，在与每种防护服模型一起测试时，单层和双层手套之间的液体泄漏量没有显著差异，除了基重和刚性最高的防护服。
