Biosafety cabinetry

摘要

The workability of operation to be performed, while preventing chemical or biological contamination, using a biosafety cabinet and gloves attached to the cabinet is improved. A biosafety cabinet includes a workspace formed in a main body cabinet thereof. Air in the workspace is discharged to outside via filters. A vertically movable front shutter is disposed on a front of the workspace. A front opening is formed below the front shutter to be at a front of the workspace. The front shutter includes plural laterally movable small windows which are overlapped like layered sliding doors. One of the plural small windows is provided, on the workspace side thereof, with a pair of glove ports to which a pair of gloves for use in operation in the workspace can be air-tightly attached.

主权项

1. A biosafety cabinet comprising:
an air exhaust unit for discharging air in a workspace formed in a main body cabinet to outside via a filter; a front shutter vertically movably installed on a front of the workspace; and a front opening formed below the front shutter at the front of the workspace, wherein the front shutter comprises:
a plurality of transparent small windows which are laterally movable,a rectangular small-window frame being provided at a first end of a first transparent small window from among the plurality of the transparent small windows,a projection being provided on at least one of a first end and a second end of a second transparent small window frame of a second transparent small window from among the plurality of the transparent small windows, the second transparent small window being different from the first transparent small window, anda pair of gloves for use in operation in the workplace being provided on the first transparent small window, wherein:
the rectangular small-window frame of the first transparent small window is in contact with the second transparent small window such that the first transparent small window overlaps the second transparent small window to maintain an air-tight seal in the workspace, andthe rectangular small-window frame of the first transparent small window is in contact with the projection of the second transparent small window frame to maintain an air-tight seal in the workplace when the first transparent small window and the second transparent small window move laterally.
