PROBLEM TO BE SOLVED: To provide a vacuum disinfecting method and disinfecting device capable of spreading an antiseptic into every corner of a treated object and dehumidifying the object without a risk of gas leakage.SOLUTION: A main conduit whose one end is a gas inlet and whose other end is a treated gas outlet is connected to a disinfecting compartment. On the way of the main conduit, a vacuum pump is connected on the inlet side, and a degrading means is connected on the outlet side from the vacuum pump sequentially. A discharge conduit with a discharge valve is connected to the downstream side of the degrading means in the main conduit, and an outside air intake conduit with an outside air intake valve is connected to the main conduit on the downstream side of the discharge conduit. Air inside the disinfection compartment is discharged from the discharge conduit by the vacuum pump when the discharge valve is opened to bring the interior of the disinfection compartment to a high vacuum, and the discharge valve is closed. After that, the outside air intake valve is opened and outside air and a disinfection gas are introduced into the disinfection compartment. When the interior of the disinfection compartment is brought to a low vacuum approximate to the atmospheric pressure, the outside air intake valve is closed and the closed state is retained for a prescribed period for disinfection. The same step is repeated thereafter. After termination of the disinfection step, a clarification step is executed in the same way. |
