摘要
目的分析现有的无针输注连接方式,特别是对密闭式无针连接方式的构造及微生物侵入对正压密闭式无针接口的影响。方法模拟临床使用方法,设计了相关的微生物侵入验证实验。结果受试组样品均未出现微生物侵入的阳性结果。结论正压密闭输液接头能有效阻止微生物的侵入。
Objective We analyze the comparison of existing needleless connections,Especially the structure of an enclosed needleless connection,and the influences of the ingress of micro-organisms to positive pressure connector.Methods Related test about ingress of micro-organisms is designed under simulated clinical application.Results Positive result was not detectable in experimental group.Conclusion Positive pressure connector can prevent the ingress of micro-organisms.
