## Abstract

Concerted processing of a multiplicity of local apparatus status messages from dialysis apparatuses can be performed to enhance the quality of patient care delivered using the dialysis apparatuses. Typically, the dialysis apparatuses are operated in a group. A control agent, as described herein, performs a central calculation of prioritised warning messages for the group of dialysis apparatuses. The prioritisation is calculated in a concerted calculation according to a preconfigured system of rules.

## Claims

### Claim 1

A networked status message system for a group of dialysis apparatuses, the system comprising:
the group of dialysis apparatuses, wherein each dialysis apparatus comprises a local signal device configured to detect local dialysis apparatus status messages and to transmit the local dialysis apparatus status messages to a control agent; and
the control agent configured to receive the local dialysis apparatus status messages and comprising an evaluation circuit, the evaluation circuit configured for: (i) accessing a system of rules and (ii) prioritizing the local dialysis apparatus status messages based on the system of rules to calculate prioritised warning messages for the group of dialysis apparatuses on the basis of the detected, local apparatus status messages,
wherein the control agent is configured to transmit the calculated, prioritised warning messages to: (i) only the local signal devices of the group of dialysis apparatuses that transmitted one or more of the local dialysis apparatus status messages to the control agent and (ii) none of the local signal devices of the group of dialysis apparatuses that did not transmit one or more of the local dialysis apparatus status messages to the control agent, and
wherein each of the local signal devices is configured to receive and display one or more of the calculated, prioritised warning messages.

### Claim 2 (depends on 1)

The system of claim 1, wherein the local signal devices of respective dialysis apparatuses are configured to be controlled in a modified manner based on the calculated, prioritised warning messages.

### Claim 3

A control agent system for calculating prioritised warning messages for a group of dialysis apparatuses, the control agent system comprising:
an input interface configured to receive local apparatus status messages from the group of dialysis apparatuses; and
an evaluator configured to access a system of rules and for evaluation of the received local apparatus status messages based on the system of rules to calculate prioritised warning messages for the group of dialysis apparatuses,
wherein the evaluator is also configured to transmit the calculated prioritised warning messages via an output interface to: (i) each dialysis apparatus of the group of dialysis apparatuses from which one or more of the local apparatus status messages were received by the control agent and (ii) no dialysis apparatuses of the group of dialysis apparatuses from which none of the local apparatus status messages were received by the control agent, and
wherein the prioritised warning messages are transmitted for display only by each dialysis apparatus from which one or more of the local apparatus status messages were received by the control agent and for control thereof based on the prioritised warning messages.

### Claim 4 (depends on 3)

The control agent system of claim 3, wherein the control agent is implemented on a medical-technical apparatus or on a central server.

### Claim 5 (depends on 3)

The control agent system of claim 3, wherein the input interface is configured to detect all local apparatus status messages from each dialysis apparatus of the group of dialysis apparatuses in a pre-configurable time interval or after an occurrence of a configurable event.

### Claim 6

A method for coordinated control of a group of dialysis apparatuses, the method comprising:
detecting local apparatus status messages from one or more dialysis apparatuses of the group of dialysis apparatuses;
collecting and consolidating all of the detected, local apparatus status messages over a period of time;
evaluating all of the collected and consolidated, detected, local apparatus status messages in order to calculate, in a concerted manner and using a system or rules, prioritised warning messages for the one or more dialysis apparatuses of the group of dialysis apparatuses that detected at least one of the local apparatus status messages; and
transmitting the prioritised warning messages to: (i) the one or more dialysis apparatuses of the group of dialysis apparatuses that detected at least one of the local apparatus status messages and (ii) none of the dialysis apparatuses of the group of dialysis apparatus that did not detect a local apparatus status message,
wherein the prioritised warning messages are transmitted for display only by the one or more dialysis apparatuses of the group of dialysis apparatus that detected at least one of the local apparatus status messages and for coordinated control thereof on the basis of the transmitted, prioritised warning messages.

### Claim 7 (depends on 6)

The method of claim 6, wherein the evaluation is performed in a coordinated manner for all dialysis apparatuses of the group of dialysis apparatuses and the evaluation is performed centrally or locally on each dialysis apparatus of the group of dialysis apparatuses.

### Claim 8 (depends on 6)

The method of claim 6, wherein for each of the prioritised warning messages an output mode is calculated and allocated, wherein the output mode comprises output of a visual warning signal, an acoustic warning signal, or a warning signal in another format, so that the prioritised warning message is output on a local signal device or on an output unit in the output mode.

### Claim 9 (depends on 6)

The method of claim 6, wherein the local apparatus status message is output in addition to the prioritised warning messages in order to represent a change in the local apparatus status message.

### Claim 10 (depends on 6)

The method of claim 6, wherein selected local apparatus status messages can be allocated a lock flag which denotes that the selected apparatus status messages must not be downgraded by the calculated, prioritised warning message.

### Claim 11 (depends on 6)

The method of claim 6, wherein the prioritised warning messages are calculated using a correlative negotiation regarding an urgency of all of the detected, local apparatus status messages using a pre-configurable system of rules.

### Claim 12 (depends on 6)

The method of claim 6, wherein the modified, coordinated control is not performed based on the local apparatus status message, but instead is performed based on the warning message which is prioritised in relation to all of the local apparatus status messages.

### Claim 13 (depends on 6)

The method of claim 6, wherein the modified, coordinated control of the group of dialysis apparatuses can be activated and deactivated or is triggered automatically after an occurrence of a pre-defined event.

### Claim 14 (depends on 6)

The method of claim 6, wherein all of the calculated, prioritised warning messages are output in an itemized addressable manner for each dialysis apparatus of the group of dialysis apparatuses.

### Claim 15 (depends on 6)

The method of claim 6, wherein all of the calculated, prioritised warning messages are stored in an itemized addressable manner for each dialysis apparatus of the group of dialysis apparatuses.

### Claim 16 (depends on 6)

The method of claim 6, further comprising:
detecting a user identity which is in each case specific for a user of a respective dialysis apparatus of the group of dialysis apparatuses; and
detecting a location of the user of the respective dialysis apparatus,
wherein, in order to calculate the prioritised warning message for the respective dialysis apparatus the detected user identity and the detected location are calculated.

### Claim 17 (depends on 6)

The method of claim 6, further comprising: (i) detecting a user identity which is in each case specific for a user of a respective dialysis apparatus of the group of dialysis apparatuses, or (ii) detecting a location of a user of a respective dialysis apparatus, wherein, in order to calculate the prioritised warning message for the respective dialysis apparatus the detected user identity or the detected location are calculated.

### Claim 18 (depends on 6)

The method of claim 6, wherein, when high-priority warning messages have been calculated for a plurality of dialysis apparatuses of the group of dialysis apparatuses, the method further comprises:
generating a request command and transmitting the request command to pre-configured entities via pre-configured data transmission channels.
