Abstract

The invention concerns a method and device for controlling a number of infusion pumps 2-10, whereby each infusion pump (2-10) has an infusate assigned to it which is administered within a pre-determinable period of time assigned to it as an infusion at a pre-determinable infusion rate to a living being, whereby the infusion pumps (2-10) exchange control data for activating and deactivating the various infusions in a chronologically coordinated manner autonomously.

Claims

1. A method for controlling several infusion pumps, each infusion pump having an infusate assigned to it which is administered to a living being for a pre-determinable period of time as an infusion at a pre-determinable infusion rate, the method comprising:

originating control data at a first infusion pump using measured or estimated physiological data of the living being, the control data comprising instructions to activate a second infusion pump, wherein the originating step comprises;

comparing the measured or estimated physiological data of the living being with a pharmacokinetic model at the first infusion pump, and

automatically originating the control data at the first infusion pump based on results of the comparison;

exchanging the control data between the first and second infusion pumps of their own accord for coordinating activating and deactivating the various infusions chronologically;

receiving a first portion of the control data at the second infusion pump from the first infusion pump; and

activating the second infusion pump in response to receipt of the first portion of the control data from the first infusion pump.

2. The method of claim 1, wherein each infusion pump processes the control data via a control unit assigned to it and sends it to at least one of the other infusion pumps.

3. The method of claim 1, wherein each infusion pump is connected to a central control device and processes control data via the central control device and processes control data via the central control device and sends it to at least one of the other infusion points.

4. The method of claim 3, wherein the central control device is composed of a number of individual control units.

5. The method of claim 1, wherein the infusion from at least one of the infusion pumps is always activated.

6. The method of claim 1, wherein the infusion from all infusion pumps is activated and/or deactivated simultaneously.

7. The method of claim 3, wherein controls on the central control device are usable to input at least one control process to control activating and deactivating the different infusions for at least two infusion pumps.

8. The method of claim 7, wherein the central control process activates and/or deactivates and/or interrupts the infusion by the two or more infusion pumps.

9. The method of claim 7, wherein selecting a treatment regime to which a control process is assigned selects the infusion pumps assignable to that treatment regime autonomously or displays them to an operator to select.

10. The method of claim 1, wherein at least one of the infusion pumps administers a dilutant to the living being in addition to a pharmaceutically active agent which is administered via another infusion pump.

11. The method of claim 1, wherein the control data deactivate the infusion of the dilutant while keeping the pharmaceutically active agent activated.

12. The method of claim 1, wherein a display device displays the infusion rates of the infusion pumps and/or measured or estimated physiological data of the living being and/or control data and/or activation and deactivation times of the infusion pumps and/or infusion periods.

13. A system for controlling a number of infusions, comprising:

a plurality of infusion pumps, each infusion pump having an infusate assigned to it which can be administered for a pre-determinable period of time as an infusion at a pre-determinable infusion rate to a living being, wherein control data for activating and deactivating the various infusions in chronologically coordinated fashion can be originated at a first infusion pump and exchanged between the first and a second infusion pump autonomously, the control data comprising instructions to activate the second infusion pump;

a first control unit in the first infusion pump, the first control unit transmitting a first portion of the control data; and

a second control unit in the second infusion pump, the second control unit receiving the first portion of control data from the first control unit and activating the second infusion pump in response to receipt of the first portion of control data from the first infusion pump,

wherein the first infusion pump is programmed to compare measured or estimated physiological data of the living being with a stored pharmacokinetic model, and automatically originate the control data at the first infusion pump based on results of the comparison.

14. The system of claim 13, wherein each infusion pump has one of the control units which processes the control data and sends it directly to control units of other infusion pumps.

15. The system of claim 13, wherein the infusion pumps and the transmission of control data between the infusion pumps are controlled chronologically dependent on one another.

16. The system of claim 13, further comprising controls on the infusion pumps for entering control commands, selecting control processes, selecting infusion pumps involved in those control processes and/or entering physiological data from the living being.

17. The system of claim 13, further comprising a display device on each infusion pump for displaying control data, measured or estimated physiological data of the living being, the times when infusion pumps are activated and deactivated, infusion periods and/or infusion rates.
