In order to control sterility of a sterilized medical device after high-temperature steam sterilization, the medical device and a sterilization module are wrapped by a wrapper and put into an autoclave to carry out sterilization, during which the sterilization module logs a time history of its own temperature and pressure in its own environment. The sterilization module assesses the efficiency of sterilization by processing the acquired data. The sterilization module shifts from a normal mode to an alarm mode after an inefficient sterilization and/or after a sterility expiration date of the medical device is over. The sterilization module signals its mode upon each jerk. A sterility status of a uniquely identified medical device is unambiguously and simply presented to a user by a lighting-up of a single light source on the sterilization module that is suitable for a routine control of the efficiency of sterilization, and is reusable.
