Safeguarding mechanisms for the operation of medical apparatuses using disposables in a dialysis environment

One or more non-transitory computer readable storage media storing instructions that, when executed by at least one programmable processor, cause the at least one programmable processor to perform operations comprising:

• reading-in a first identifier for identifying a first linking partner of the at least two linking partners in a unique manner and a second identifier for identifying a second linking partner of the at least two linking partners 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 that defines a unique signature of each instance of a linking event between the first and second linking partners, wherein calculating the documentation value includes calculating a third identifier as a repetition value which uniquely represents a number of repetitions for a linking event between the first and second linking partners so repetitions of linking events can be documented in a distinguishable manner using a unique signature of the linking partners involved in the linking events;
• 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.

A safeguarding module for an apparatus for the medical environment, the safeguarding module comprising:

• a read-in interface for reading-in a first identifier and a second identifier;
• at least one processor programmed with instructions to perform operations comprising:
• reading-in a first identifier for identifying a first linking partner of the at least two linking partners in a unique manner and a second identifier for identifying a second linking partner of the at least two linking partners 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 that defines a unique signature of each instance of a linking event between the first and second linking partners, wherein calculating the documentation value includes calculating a third identifier as a repetition value which uniquely represents a number of repetitions for a linking event between the first and second linking partners so repetitions of linking events can be documented in a distinguishable manner using a unique signature of the linking partners involved in the linking events;
• 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;
• an interface to a memory or with a memory for storing the calculated documentation value;
• and
• an interface to a network, via which the apparatuses exchange data.

A system for safeguarding an apparatus in the medical environment against an unauthorised operation of the apparatus, the system comprising one or more computers and one or more computer storage media storing instructions that are operable, when executed by the one or more computers, to cause the one or more computers to perform operations comprises:

• reading-in a first identifier for identifying a first linking partner of the at least two linking partners in a unique manner and a second identifier for identifying a second linking partner of the at least two linking partners 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 that defines a unique signature of each instance of a linking event between the first and second linking partners, wherein calculating the documentation value includes calculating a third identifier as a repetition value which uniquely represents a number of repetitions for a linking event between the first and second linking partners so repetitions of linking events can be documented in a distinguishable manner using a unique signature of the linking partners involved in the linking events;
• 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.
