| 摘要 |
The present invention discloses a sterilization indicator for a sterile container, having a shape-memory element in the form of an axially acting compression spring, preferably of the helical-spring type, which, when a predetermined sterilization temperature is reached or exceeded, subjects an indicating unit to a defined axial compressive force, said indicating unit, in turn, being prestressed by means of a restoring spring, preferably of the helical-spring type, in the direction counter to the shape-memory element by way of a restoring force which is smaller than the defined axial compressive force, and having a latching mechanism, which can be actuated by a manually actuable closing or locking mechanism of the sterile container and is designed such that, following or during the operation of the sterile container being closed or locked, it retains the indicating unit in a sterile position once said unit has been moved into the sterile position by the shape-memory element and, upon opening or unlocking of the sterile container below the sterilization temperature, it frees the indicating unit, whereupon the restoring spring moves the indicating unit back into an unsterile position. |
