Method for temporarily interrupting an extracorporeal blood treatment, control device and blood treatment apparatus

A method for temporarily interrupting an extracorporeal blood treatment of a patient who is connected to a blood treatment apparatus for the extracorporeal blood treatment, the method comprising:

• connecting an extracorporeal blood circuit to the patient, the extracorporeal blood circuit connected to the blood treatment apparatus and comprising:
• a blood withdrawal line connected to the patient;
• and
• a blood return line connected to the patient;
• activating or controlling a control device of the blood treatment apparatus to start the extracorporeal blood treatment, the extracorporeal blood treatment comprising running a blood pump to:
• (i) withdraw blood from the patient;
• (ii) convey the blood through the extracorporeal blood circuit;
• and (iii) return the blood to the patient, the control device configured to bring the blood treatment apparatus into a temporary interruption state in which a session of the extracorporeal blood treatment can be interrupted temporarily to, at a later time, continue the session of the extracorporeal blood treatment;
• during the extracorporeal blood treatment, activating or controlling the control device to bring the blood treatment apparatus into the temporary interruption state, wherein, during the temporary interruption state, blood from the blood withdrawal line is conveyed by the blood pump to perform a reinfusion of the blood from the blood withdrawal line to the patient;
• after stopping the blood pump, disconnecting the patient from the extracorporeal blood circuit, and then circulating at least one substituate liquid through at least one section of the extracorporeal blood circuit while the patient is disconnected from the extracorporeal blood circuit during the temporary interruption state;
• after the stopping of the blood pump, receiving a notification generated by the control device in response to the stopping of the blood pump, the notification comprising a request to the patient or a user of the control device to confirm if the patient has been disconnected from the extracorporeal blood circuit;
• confirming that the patient has been disconnected from the extracorporeal blood circuit;
• in response to confirming, receiving one or more messages, generated by the control device at respective steps of the temporary interruption of the session of the extracorporeal blood treatment, to inform the patient or the user of the control device about a next operation step of the temporary interruption;
• reconnecting the patient to the extracorporeal blood circuit;
• and
• after the reconnecting, activating or controlling the control device to continue the session of the extracorporeal blood treatment using the blood treatment apparatus.
