Isolator system
An isolator system includes an isolator, passbox, clean booth, and decontamination gas supply. The isolator includes a sterile operation area and a wearing entity for an operator. The passbox enables introducing an object into the sterile operation area. The clean booth, encloses an insertion port of the wearing entity and an inlet port for introducing the object into the passbox. A clean gas supply supplies clean gas to the sterile operation area and to the clean booth. The decontamination gas supply supplies decontamination gas into the sterile operation area and the clean booth. After an interior of the sterile operation area and the clean booth are decontaminated, pressures of the sterile operation area and the clean booth are maintained at least equal to a building pressure and the pressure of the clean booth is maintained lower than a pressure of the sterile operation area.
1. An isolator system, comprising:
an isolator in which a sterile operation area is provided and which includes a wearing entity for an operator to operate externally;
a pass box for transferring an object into the sterile operation area;
a clean booth into which an operator can enter, which encloses at least an external insertion port of the wearing entity of the isolator and an object inlet port for inserting the object into the pass box,
a clean gas supply that supplies clean air to an interior of the clean booth and, from the clean booth to the sterile operation area; and
a decontamination gas supply that includes a plurality of switches that selectively supply decontamination gas into the sterile operation area, the clean booth and the pass box,
the isolator, the pass box, and the clean booth being arranged in a building, and
after an interior of the sterile operation area and the clean booth are decontaminated with the decontamination gas to achieve a decontaminated condition, by the decontamination gas supply, interior pressures of the sterile operation area and of the clean booth are maintained equal to or higher than an environmental pressure in the building, by the clean gas supply to maintain the decontaminated condition and the interior pressure of the clean booth is maintained lower than the interior pressure of the sterile operation area.
2. The isolator system according to claim 1 , further comprising an air lock room between the clean booth and an ambient environment, wherein an interior air pressure of the air lock room is maintained higher than an ambient pressure in the building.
3. The isolator system according to claim 1 , wherein the pass box is divided into a plurality of sections.
4. The isolator system according to claim 1 , the pass box comprising a first pass box, the system further comprising a second pass box having an outlet port for transferring an object out of the sterile operation area, the second pass box being provided opposite the first pass box with respect to the sterile operation area, the clean booth enclosing the outlet port.
5. The isolation system according to claim 1 , further comprising a dust removal pass box and a sterilization pass box that are configured to receive an object and to convey the object to the sterile operation area.
