Device and method for generating and displaying graphic codes specific for medical devices and medical treatment

The method for extracting information based on a medical fluid management machine and/or a treatment performed or to be performed therewith, comprising the steps:

• entering a graphic code which graphically encodes encrypted information which is based on the medical fluid management machine and/or a treatment already performed or to be performed therewith by using a key which is specific for a given person or is specific for a group of people, said information being based on the medical fluid management machine and/or a treatment performed or to be performed therewith,
• decoding the graphic code to recover the encrypted information, decryption of the decoded information to recover the information based on the medical fluid management machine and/or the treatment already performed or to be performed therewith, using the key of the at least one graphic code, this code being specific for a given person or for a group of people, can be recovered, and the information thereby retrieved can be processed further, in particular by display of the decrypted information.

A fluid management machine having a display device and a control unit wherein the control unit is equipped to encrypt a graphic code containing information based on the medical fluid management machine or a treatment performed or to be performed with it using a key which is specific for a given person or for a group of people and wherein the control unit is additionally equipped to generate a graphic code based on the encrypted information and to display the graphic code on the display device.

A mobile computer for obtaining information based on a medical fluid management machine and/or a treatment that has been performed or is to be performed therewith by using a control unit, and a reader for reading a graphic code wherein the control unit is equipped to decode information based on a medical fluid management machine and/or a treatment that has been performed or is to be performed therewith, which is encoded and encrypted using the key specific for a given person or a group of people and to decrypt the code using the key that is specific for a given person or a group of people.

A method for display of graphic codes wherein the graphic codes encode information and wherein different graphic codes are displayed one after the other over a display period and wherein the display period defines the period of time in which the graphic codes are displayed without repetition.
