With this working room 20
A shutter 24 is provided in the front opening 22 so as to be freely openable and closable so as to prevent contamination of an article handled by the outside air during work.

Further, a sterile storage cabinet 26 is integrally attached to one side of the aseptic workbench 10, and the storage cabinet 26 is also provided with the outside air sucked through the pre-filter 28 and the passage 30 by a blower 32. After being cleaned by the filter 34, the sterile storage 26 is pressure-fed and the storage 26 is kept clean. In this case, as the main filters 18 and 34, it is preferable to use HEPA filters having a high dust collecting ability.

On the other hand, an opening 38 is provided in the partition wall 36 between the aseptic working chamber 20 and the aseptic storage 26, and an internal shutter 40 made of transparent glass or the like is preferably arranged in the opening 38 so as to be openable and closable.

In this case, it goes without saying that an opening / closing door may be used instead of the internal shutter 40.

Further, when the clean air is fed into the aseptic work room 20 and the aseptic storage 26, as in the present embodiment, a part of the clean air,
The workbench 42 and the sterile storage cabinet 26 are formed so as to flow back to the pre-filters 12 and 28 through the punching metals 44 and 46 of the reflux ports respectively provided on the bottoms of the sterile work chamber 20 and the sterile storage cabinet 26. The air volumes of the blowers 16 and 32 and the thicknesses of the main filters 18 and 34 are set so as to maintain the same positive pressure atmosphere.

When using the aseptic workbench 10 according to the present invention configured as described above, the front door 48 is operated to store the items to be handled in the aseptic storage 26 in advance. Since the air cleaned by the filter 34 is circulated, the handled article is kept aseptic.

Then, the worker opens the shutter 24 of the front opening 22 to a required degree, opens the internal shutter 40, and carries in the article to be handled in the aseptic storage 26 onto the workbench 42 for the work. During these series of operations, since the highly purified air is maintained in the same positive pressure atmosphere in the aseptic work chamber 20 and the aseptic storage 26, turbulence due to the clean air is generated even if the internal shutter 40 is opened. It does not occur, and the articles to be handled can be carried into the workbench 42 without exposing them to the outside air.

2a shows an embodiment in which a dryer 50 consisting of a heater is provided in the passage 30 of the aseptic storage 26, and FIG. 2b shows an aseptic lamp 52 such as an ultraviolet lamp provided in the aseptic storage 26.

Further, as shown in FIG.
It is another embodiment of the present invention in which a and 26b are integrally attached, but in this case, one aseptic storage cabinet 26a stores the articles before handling and the other aseptic storage cabinet 26b stores the items after handling. By storing the articles, the required work can be performed in one direction and can be performed efficiently, and confusion of the articles before and after handling can be avoided.

Furthermore, FIG. 4 shows an internal shutter 54 movable up and down on both sides of the aseptic storage boxes 26a, 26b of the aseptic workbench 10 shown in FIG.
This is a further embodiment of the present invention in which washing machines 56a and 56b such as an air shower device and a washing water spraying device which are capable of being isolated from each other are additionally provided. After washing with the washing machine 56a, the washed article is moved to the aseptic storage cabinet 26a by opening the internal shutter 54, and then the work table 42 is operated to wash the articles stored in the aseptic storage cabinet 26b with the washing machine 56b again. Since it can be carried out to the storage room after that, complete and reliable aseptic work can be performed.

[Effect of device]
