Application of a high-velocity steam-air micromist jet spray (HVS-AMJS) with disinfectants for cleansing the skin is proposed. Low-pressure steam is mixed with compressed air in a nozzle and then sprayed onto a surface of skin or material located approximately 22 cm from the nozzle. The temperature on the sprayed surface was controlled between 40ºC and 45 ºC. The improved HVS-AMJS installed scattering prevention cover with tap water effectively removed normal bacterial flora (total viable count and coliform bacteria) from contaminated skin pieces and pig skin wounds. Furthermore, the cleansing efficacy increased by advanced-treating with bio-shell calcium oxide (BiSCaO), hypochlorous acid (HClO), sodium hypochlorite (NaClO), povidone iodine, or chlorhexidine gluconate. Especially, the improved HVS-AMJS combined with BiSCaO had higher bactericidal activity than when combined with other disinfectants. This study suggests that application of the HVS-AMJS with disinfectants, especially BiSCaO, may be useful for skin cleansing to prevent infection.
有人提出应用一种带有消毒剂的高速蒸汽-空气微雾喷射器（HVS-AMJS）来清洁皮肤。低压蒸汽在喷嘴中与压缩空气混合，然后喷到距离喷嘴约22厘米处的皮肤表面或材料上。被喷表面的温度控制在40℃至45℃之间。安装了防散射罩并使用自来水的改进型HVS-AMJS能有效去除污染皮肤碎片和猪皮肤伤口上的正常细菌菌群（总活菌数和大肠菌群）。此外，通过用生物壳氧化钙（BiSCaO）、次氯酸（HClO）、次氯酸钠（NaClO）、聚维酮碘或葡萄糖酸氯己定进行预处理，清洁效果得到了提高。特别是，改进型HVS-AMJS与BiSCaO结合时的杀菌活性高于与其他消毒剂结合时的杀菌活性。本研究表明，应用带有消毒剂的HVS-AMJS，尤其是BiSCaO，可能对皮肤清洁以预防感染有用。
