Description
Technical Field
The utility model relates to a BD tests technical field, concretely relates to pressure steam sterilization lumen BD testing arrangement.
Background
Pressure steam sterilization is a sterilization mode aiming at high temperature and high humidity resistant instruments in hospitals. It is a diagnostic test of a sterilizer vacuum system. This test allows assessment of inadequate vacuum conditions, meaning that air remains in the sterilizer cabinet as a result of incomplete air removal from the sterilizer cabinet or air leakage from the door's sealing gasket. This residual air prevents steam penetration of the items within the sterilizer cabinet during the steam exposure phase of the sterilization process.
This diagnostic test uses an sterilization indicator tape (autoclave tape) attached to a piece of paper to form a cross pattern (st. These sterilization indicator tapes are coated with chemical test paper. The paper is placed between linen interwoven fabrics with 29 to 36 plies. The wrapped test pack was placed above the sterilizer vent of an empty cabinet for sterilization at 134 ℃ for 3.5 minutes.
The paper containing the sterilization indicator tape (hereinafter referred to simply as test paper) was removed from the test pack and observed for a uniform color change of the test paper in the tape. The presence of a non-uniform or relatively shallow test strip in the center of the paper (where the tapes cross each other) indicates that vapor penetration into the center of the package is impeded. This non-uniform indicator indicates that steam cannot reach the center of the test pack due to the presence of residual air within the sterilizer cabinet.
