In times of collective concern about pandemics, body-shield resuscitation barrier devices are more and more considered to protect against transmission of different pathogens between rescuers and patients. The objective of this experimental study was to investigate the characteristics of blood drops dispersed on the surface of four different foils suitable for blanketing patients during resuscitation. We analyzed run-off characteristics of blood stains depending on surface properties of polyvinyl chloride, polyethylene, polyethylene terephthalate and aluminum-coated polyethylene terephthalate. Confocal fluorescence microscopy revealed less cellular density and lack of fibrin networks in blood stains on the four foil surfaces than on paper towel. Delayed clotting went along with larger areas of contamination indicating a greater likelihood of coming into contact with potential germs but a smaller chance of contracting an infection. Space blankets as obligatory components of first aid kits are readily available for rescuers and serve as a mechanical barrier between rescuers and patients during resuscitation.
在人们普遍关注大流行病的时候，身体盾牌复苏屏障设备越来越多地被认为可以防止救援人员和患者之间不同病原体的传播。本实验研究的目的是研究四种不同箔片表面上血液滴的分散特征，这些箔片适用于在复苏期间覆盖患者。我们根据聚氯乙烯、聚乙烯、聚对苯二甲酸乙二醇酯和镀铝聚对苯二甲酸乙二醇酯的表面特性分析了血斑的流淌特性。共焦荧光显微镜显示，与纸巾相比，在四种箔片表面上的血斑中细胞密度更低，缺乏纤维蛋白网络。凝血延迟伴随着更大的污染面积，这表明与潜在细菌接触的可能性更大，但感染的机会更小。太空毯是急救箱的必备组件，对救援人员来说很容易获得，并且在复苏期间作为救援人员和患者之间的机械屏障。
