Process challenge device for a high-pressure steam sterilizer and sheet for a challenge device

Abstract

An object of the present invention is to provide a process challenge device for a high-pressure steam sterilizer capable of reuse with little trouble. A process challenge devicefor a high-pressure steam sterilizer, includes a plurality of stacked steam permeable bodies, andformed by a material capable of permeating of steamand an indicator. The steam permeable bodies(except the steam permeable bodiesandarranged at both sides among the stacked steam permeable bodies, and) each have an openingfor accommodating the indicator. The steam permeable bodies, andare stacked, so that the indicatoris surrounded by the inner wall of a cavityformed by the openingsof the intermediate steam permeable bodies communicated with one another and the steam permeable bodiesandarranged at both sides. The indicatoris contained in the cavity, so that a groupof the above-mentioned stacked steam permeable bodies containing the indicatortherein is fitted into and taken out of a casingat will.
