Abstract

Provided is a sterile environment maintaining apparatus capable of sterilizing a sterile room in a shorter time than conventional ones.

The sterile environment maintaining apparatus according to the present invention comprises a sterile room 10 having an inlet opening 11 and an outlet opening 12, a HEPA filter 3 placed so as to cover the inlet opening 11 or the inlet opening 11 and the outlet opening 12 of the sterile room 10, and a sterilizing material supplying part supplying a sterilizing material such as hydrogen peroxide to the sterile room 10, and the sterile room 10 is provided with a detoxifying material supplying part spraying a detoxifying material such as ozone toward the HEPA filter 3.

Claims

1. A sterile environment maintaining apparatus comprising a sterile room having an inlet opening and an outlet opening, a fine particle capture filter placed so as to cover the inlet opening or the inlet opening and the outlet opening of the sterile room, and a sterilizing material supplying part supplying a sterilizing material to the sterile room, wherein the sterile environment maintaining apparatus is provided with a detoxifying material supplying part releasing a detoxifying material for detoxifying the sterilizing material toward the fine particle capture filter.

2. The sterile environment maintaining apparatus according to claim 1, wherein the detoxifying material supplying part releases the detoxifying material toward an inlet opening side surface of the fine particle capture filter placed so as to cover the inlet opening.

3. The sterile environment maintaining apparatus according to claim 1, wherein the sterilizing material supplying part supplies gas or liquid fine particle including the sterilizing material to the sterile room, and the detoxifying material supplying part supplies gas or liquid fine particle including the detoxifying material toward the fine particle capture filter.

4. The sterile environment maintaining apparatus according to claim 1, wherein the sterilizing material is a first active oxygen species, and the detoxifying material is a second active oxygen species.

5. The sterile environment maintaining apparatus according to claim 1, wherein the sterilizing material is hydrogen peroxide or ozone, and the detoxifying material is alkaline water.

6. A sterile environment maintaining apparatus comprising a sterile room having an inlet opening and an outlet opening, a fine particle capture filter placed so as to cover the inlet opening or the inlet opening and the outlet opening of the sterile room, and a sterilizing material supplying part supplying a sterilizing material to the sterile room, wherein the sterile environment maintaining apparatus is provided with irradiating means for detoxifying the sterilizing material toward the fine particle capture filter.

7. The sterile environment maintaining apparatus according to claim 6, wherein, the sterilizing material is an active oxygen species, and the irradiating means is either of an ultraviolet irradiation device, an ultrasound irradiation device, a heat irradiation device or an infrared irradiation device, or any combination thereof.

8. A sterile environment maintaining apparatus comprising a sterile room having an inlet opening and an outlet opening, a fine particle capture filter placed so as to cover the inlet opening or the inlet opening and the outlet opening of the sterile room, and a sterilizing material supplying part supplying a sterilizing material to the sterile room, wherein the fine particle capture filter includes a detoxifying material for detoxifying the sterilizing material.

9. The sterile environment maintaining apparatus according to claim 8, wherein the detoxifying material is a material including one or more of oxidant, reducing agent, activated carbon, platinum, ferric oxide, copper oxide, manganese oxide, catalase, fullerene, zinc complex of porphyrine, and compound of chlorophyll class.
