Title: DECONTAMINATION ARRANGEMENT, SYSTEM AND DECONTAMINATION METHOD
Abstract:
The invention relates to a decontamination arrangement, in particular for pharmaceutical uses, comprising at least one space (4) to be decontaminated, in particular an isolator space, preferably a manipulator space and/or a plenum space separated from the manipulator space by a membrane, with a decontamination liquid reservoir (36) from which several atomizers (A, B, C, D), arranged in the space (4) to be decontaminated and preferably configured as two-substance nozzles, and serving to generate a decontamination aerosol, can be supplied with decontamination liquid, preferably hydrogen peroxide, via valve means (27) controllable by electronic control means, wherein the atomizers (A, B, C, D) are connected fluidically via the valve means (27) to a ring line (32) which has an inlet (33) and, separate therefrom, an outlet (34), into the inlet of which decontamination liquid from the decontamination liquid reservoir (36) can be delivered by means of a pump (35), and from the outlet of which decontamination liquid can flow back into the decontamination liquid reservoir (36), and wherein the ring line (32) is assigned pressure-adjusting means (37) for keeping the liquid pressure in the ring line (32) in a predefined liquid pressure range. According to the invention, measuring means (40) are provided for determining a total quantity of decontamination liquid delivered to the atomizers (A, B, C, D) during a decontamination cycle, in particular comprising weighing means (41) for determining a quantity of decontamination liquid in the decontamination liquid reservoir (36).
