の検出法と殺菌法とを併せて改善したものである。However, an operation transmission device of a system using a bellows tube, which has been used in the conventional method for isolating the aseptic chamber from the outside,
Alternatively, in the case of an operation transmission device that uses a steam barrier device, it is difficult to find that it has been damaged when it breaks, and bacteria enter from this damaged part and contaminate the inside of the sterile chamber, resulting in defective products. There was an occasion. In particular, the actuation transmission device using the bellows tube has a large problem because it does not have a sterilizing function in the device. And, the breakage of this actuation transmission device is often difficult to find in many cases. As a countermeasure against this, conventionally, the damage is found by a strict regular manual diagnosis, or the operation transmission device is periodically replaced with a new one to prevent contamination by bacteria in the sterile chamber due to the damage. The present invention is an improvement of both the method of detecting a damaged portion and the method of sterilization of an operation transmission device using a bellows tube, which is particularly problematic.
