Abstract

A network for monitoring bodily functions of a patient is disclosed. The network comprises at least two distinct network nodes that can be connected to a body of the patient. At least two of the network nodes can have at least one medical function, such as, for example, a diagnostic function and/or a medication function. The network nodes can communicate directly with one another via the body of the patient and can interchange data and/or commands.

Claims

1. A network for monitoring bodily functions of a patient, the network comprising:

at least two network nodes connected to a body of the patient, wherein each of the at least two network nodes have at least one medical function, wherein the at least two network nodes communicate directly with one another via the body of the patient and interchange data and/or commands and wherein the at least two network nodes control the network.

2. The network according to claim 1, wherein at least one of the at least two network nodes comprises at least one of the following sensors:

a sensor for registering at least one analyte in a bodily fluid;

a sensor for registering at least one bodily function;

a blood-pressure sensor;

an oximeter;

a heart-rate monitor;

a motion detector;

a temperature sensor;

or combinations thereof.

3. The network according to claim 2, wherein the at least one analyte in a bodily fluid is glucose, lactate, CO₂, Hb, Hb-O₂ or combinations thereof.

4. The network according to claim 2, wherein the at least one bodily function is kidney function.

5. The network according to claim 1, wherein at least one of the at least two network nodes comprises at least one sensor that is wholly or partly be implanted into the body of the patient, wherein the implantable sensor registers at least one measurement variable in a body tissue and/or a bodily fluid.

6. The network according to claim 5, wherein the at least one measurement variable is a concentration of at least one analyte.

7. The network according to claim 1, wherein at least one of the at least two network nodes comprises at least one actuator, wherein the at least one actuator comprises an actuator for influencing at least one bodily function.

8. The network according to claim 7, wherein the actuator comprises an electrical actuator, a mechanical actuator, a valve, a medication actuator, or combinations thereof.

9. The network according to claim 8, wherein the valve is a valve for urinary control.

10. The network according to claim 8, wherein the medication actuator is a medication pump.

11. The network according to claim 1, wherein at least one of the at least two network nodes comprises at least one sensor for registering at least one measurement variable and wherein at least one of the other network nodes comprises at least one therapeutic device, wherein the network controls and/or regulates the therapeutic device according to the at least one measurement variable via the body of the patient.

12. The network according to claim 11, wherein the at least one therapeutic device is a medication device.

13. The network according to claim 1, wherein all network nodes control the network.

14. The network according to claim 1, wherein the network nodes communicate over asynchronous data transmission.

15. The network according to claim 1, wherein at least one of the at least two network nodes comprises an indication device.

16. The network according to claim 15, wherein the indication device can be worn on a wrist of a patient.

17. The network according to claim 15, wherein the indication device is integrated into a wrist watch.

18. The network according to claim 1, wherein at least one of the at least two network nodes carries out a failsafe function and carries out at least one error routine if an error state is identified.

19. The network according to claim 1, wherein at least one of the at least two network nodes emits an alarm to the patient if there is a malfunction of the network and/or if abnormal bodily functions occur.

20. The network according to claim 1, wherein at least one of the at least two network nodes communicates outside of the body.

21. The network according to claim 20, wherein the communication is far-field communication.

22. The network according to claim 20, wherein the communication is for uploading and/or downloading data.

23. The network according to claim 1, wherein at least one of the at least two network nodes extracts energy from the body and/or from surroundings of the body and uses this energy to supply the network node and/or other network nodes with energy.

24. The network according to claim 23, wherein the least one network node comprises at least one electrochemical sensor, wherein the electrochemical sensor registers at least one measurement variable in a sensor mode and wherein the electrochemical sensor extracts energy by electrochemical means in an energy-extraction mode.

25. The network according to claim 1, further comprising, at least one portable hand-held instrument, wherein the portable hand-held instrument has at least one indication function and is integrated into the network and is decoupled from the network, wherein the network automatically links the portable hand-held instrument into the network when the hand-held instrument makes contact with the body of the patient.

26. The network according to claim 25, wherein the at least one portable hand-held instrument comprises a medical measurement instrument, a cellular telephone or combinations thereof.

27. The network according to claim 25, wherein the network automatically links the portable hand-held instrument into the network when the hand-held instrument makes contact with a hand of the patient.

28. A network node having at least one medical function for use in a network as claimed in claim 1, the network node comprising:

at least one communication unit connected to the body of the patient which communicates directly with other network nodes of the network via the body of the patient and interchanges data and/or commands, wherein at least two of the network nodes control network.

29. The network node according to claim 28, wherein the at least one medical function comprises a diagnostic function, a medication function or combinations thereof.

30. A medical system, the medical system comprising:

at least one communication device, wherein the communication device detects the presence of the network as claimed in claim 1 and communicates with the network, wherein the medical system interchanges data and/or commands with the network.

31. The medical system according to claim 30, wherein the medical system comprises a surgical system, an intensive care medical system or combinations thereof.

32. The medical system according to claim 30, wherein the communication device automatically detects the presence of the network.

33. The medical system according to claim 30, wherein the communication device communicates with the network over far-field communication.
