Abstract

A device for calibrating gas electrodes inserted into a gas testing container within sterile environment of an operation room is mounted on a movable frame and has one side to be sterilized and carrying a work table with the gas testing container and another side at which a nonsterile person operates. A gas supply unit is mounted on another side of the frame. Those two sides are separated from each other by a yoke which supports gas hoses extended between the gas testing container and the gas supply unit.
