The literature is reviewed to demonstrate the significant amount of contamination on the external surface of the anesthetic cartridge diaphragm. Current methods of cartridge diaphragm decontamination to prevent injection of pathogens are discussed. A series of bacteriologic tests were conducted to determine the probability of transfer of pathogens from the diaphragm surface through the needle lumen of three different sizes to the deposition site. Results of needle purging suggest that a significant reduction in the transfer of microorganisms is possible using this technique.
本文献综述旨在证明麻醉药筒隔膜外表面存在大量污染物。讨论了目前用于药筒隔膜去污以防止病原体注射的方法。进行了一系列细菌学测试，以确定病原体从隔膜表面通过三种不同尺寸的针腔转移到沉积部位的可能性。针冲洗的结果表明，使用该技术可显著减少微生物的转移。
