Safeguarding Mechanism for the Operation of Medical Apparatuses Using Disposables in a Dialysis Environment

A method for safeguarding an apparatus in the medical environment against an unauthorised operation of the apparatus, wherein the apparatus is connected to other apparatuses via a network, and wherein the authorisation is dependent upon a linking event between at least two linking partners within the framework of an operation of the apparatus, wherein one of the linking partners is an item of use which is used during the operation of the apparatus, the method comprising:

• reading-in a first identifier for identifying a first linking partner in a unique manner and a second identifier for identifying a second linking partner in a unique manner;
• applying at least a first calculation rule to the read-in first identifier and applying a second calculation rule to the second identifier for calculating a documentation value which uniquely represents a linking event between the first and second linking partners;
• causing synchronised storage of the calculated documentation value in memories of apparatuses of the network;
• and
• safeguarding the operation of the apparatus for the first and second linking partners.
