title: [The performance of the microbial barrier of needleless positive pressure closed connectors].
abstract: OBJECTIVE
  Analyzing the performance of microbial barrier of needleless positive pressure closed connectors.
  
  
  METHODS
  Three kinds of brand needleless positive pressure closed connectors were chosen to do the access of microorganisms test.
  
  
  RESULTS
  Positive results were detected in the three experimental groups.
  
  
  CONCLUSIONS
  So far, lots of the connectors are not qualified strictly on the market, some improvement is required in the structure design and process.
