Abstract

The invention concerns a system for monitoring and controlling a patient (1), with a patient sensor (2) for capturing a patient signal, and a user interface (6) for providing a user with information on the captured patient signal, wherein the system comprises an integrated closed loop controller (4) which is fed with the patient signal and which controls a patient treating device (5) for treating the patient (1). Thus, an easy and efficient way of monitoring and controlling a patient is provided.

Claims

1. A system for monitoring and controlling a patient, with

a patient sensor for capturing a patient signal, and

a user interface for providing a user with information on the captured patient signal, wherein

the system comprises an integrated closed loop controller which is fed with the patient signal and which controls a patient treating device for treating the patient.

2. The method according to claim 1, wherein the system comprises a monitoring processer for processing the patient signal and for outputting processed data to the user interface, and further comprises a control processer for processing the patient signal and for outputting processed data to the closed loop controller, wherein the monitoring processer and the control processer are fed with the same patient signal in the same pre-processing state.

3. The method according to claim 1, wherein the system comprises an alarming unit which is fed with the patient signal and which is adapted for providing common alarm conditions for monitoring and controlling.

4. The method according to claim 1, wherein the user interface is adapted for indicating and/or inputting monitoring data and control data.

5. The method according to claim 4, wherein the user interface is adapted for requesting the user to input external data required as input data for the closed loop controller.

6. A method for monitoring and controlling a patient, comprising the following steps:

capturing a patient signal,

providing a user with information on the captured patient signal,

feeding a closed loop controller with the patient signal, and

controlling a treatment of the patient with the closed loop controller

7. The method according to claim 6, wherein the patient signal is processed for a monitoring purpose and output as processed data to the user, and the patient signal is processed for a control purpose and output as processed data to the closed loop controller, wherein processing the patient signal for the monitoring purpose and processing the patient signal for the control purpose are based on the same patient signal in the same pre-processing state.

8. The method according to claim 6, wherein common alarm conditions for monitoring and controlling are determined.

9. The method according to claim 6, wherein for indicating and/or inputting monitoring data and control data a common user interface us used.

10. The method according to claim 9, wherein a user is requested to input external data required as input data for the closed loop controller via the common user interface.

11. The method according to claim 6 wherein controlling the treatment of the patient is based on an input value, the input value is compared to an output value of the captured patient signal, and a further action is generated if the output value deviates from an expected output value by more than a predefined amount.

12. The method according to claim 11, wherein the further action is an alarm and/or fallback to an open loop control.

13. The method according to claim 11, wherein the input value is intentionally varied.
