Residual contamination extraction bag and residual contaminants extraction method of medical equipment

摘要

PROBLEM TO BE SOLVED: To provide a residual contaminant extraction bag, suitable for easily and sure determining the presence of residual contaminants on medical instruments, cleaned after use by an extraction method.;SOLUTION: The residual contaminant extracting bag 1A, comprising a thermoplastic resin and having a contact bonding zipper 2 on the side of its opening part 1a, has a constricted part 3 of a bag inner space 10, on the way reaching the bottom part of the bag from the opening part 1a and the bag inner space 10 has a shape contracted to the constricted part 3 from the opening part 1a in its left and right width, and expanded toward the bottom part of the bag from the constricted part 3. When the residual contaminant extracting bag is used, an extraction liquid L is housed in the extraction bag 1A and opens the opening part 1a upward and a hemostatic forceps 20 is inserted in the extraction bag 1A from its clamp parts 22 and 22, while the pivotal part 24 of the hemostatic forceps 20 is positioned in the vicinity of the constricted part 3 and the clamp parts 22 and 22 are subjected to on-off operation by operating the handle parts 23 and 23 of the hemostatic forceps 20 that is out of the extraction bag 1A.;COPYRIGHT: (C)2007,JPO&INPIT
