Abstract

At least an electroencephalogram (EEG) detected by a sensor is input from a signal input section as a vital sign signal. The vital sign signal is stored in a storage as vital sign data. A display includes a first display area, a second display area and a third display area. A controller reads out the vital sign data from the storage to display the vital sign signal on the display. The controller includes a first display processor, which displays the EEG in a real time manner, on the first display area, a second display processor, which displays the EEG at a time point in past, on the second display area, and a third display processor, which displays a time-varying trend of a parameter of the EEG, on the third display area. A designator designates a time point in past in the trend displayed in the third display area, so that the EEG at the designated time point is displayed on the second display area.

Claims

1. A vital sign display monitor, comprising:

a signal input section, from which at least an electroencephalogram (EEG) detected by a sensor is input as a vital sign signal;

a storage, in which the vital sign signal is stored as vital sign data;

a display, simultaneously displaying a first display area, a second display area and a third display area;

a controller, which reads out the vital sign data from the storage to display the vital sign signal on the display, the controller including;

a first display processor, which displays the EEG in a real time manner, on the first display area;

a second display processor, which displays the EEG at a time point in the past, on the second display area; and

a third display processor, which displays a time-varying trend of a parameter of the EEG, on the third display area; and

a designator, which designates a time point in the past in the trend displayed in the third display area, so that the EEG at the designated time point is displayed on the second display area.

2. The vital sign display monitor as set forth in claim 1, wherein the controller includes a filter which eliminates noise from the electroencephalogram to be displayed on at least one of the first display area and the second display area.

3. The vital sign display monitor as set forth in claim 1, wherein the controller includes a filter which eliminates noise from the trend to be displayed on the third display area.

4. The vital sign display monitor as set forth in claim 3, wherein the noise is stemmed from a cardiac potential.

5. A vital sign display monitor, comprising:

a signal input section, from which at least an electroencephalogram (EEG) detected by a sensor is input as a vital sign signal;

a storage, in which the vital sign signal is stored as vital sign data;

a display, simultaneously displaying a first display area, a second display area and a third display area;

a controller, which reads out the vital sign data from the storage to display the vital sign signal on the display, the controller including;

a first display processor, which displays the EEG in a real time manner, on the first display area;

a second display processor, which displays the EEG at a time point in the past, on the second display area; and

a third display processor, which displays a time-varying trend of an amplitude of the EEG, on the third display area; and

a designator, which designates a time point in the past in the trend displayed in the third display area, so that the EEG at the designated time point is displayed on the second display area.

6. The vital sign display monitor as set forth in claim 5, wherein the controller includes a filter which eliminates noise from the trend to be displayed on the third display area.

7. The vital sign display monitor as set forth in claim 5, wherein the controller includes a filter which eliminates noise from the electroencephalogram to be displayed on at least one of the first display area and the second display area.

8. The vital sign display monitor as set forth in claim 7, wherein the noise is stemmed from a cardiac potential.

9. The vital sign display monitor as set forth in claim 6, wherein the noise is stemmed from a cardiac potential.

10. A vital sign display monitor, comprising:

a signal input section, from which at least an electroencephalogram (EEG) detected by a sensor is input as a vital sign signal;

a storage, in which the vital sign signal is stored as vital sign data;

a display, simultaneously displaying a first display area and a second display area;

a controller, which reads out the vital sign data from the storage to display the vital sign signal on the display, the controller including;

a first display processor, which displays the EEG in a real time manner, on the first display area; and

a second display processor, which displays the EEG at a time point in the past, on the second display area; and

a designator, which designates a certain time point in the past, so that the EEG at the designated time point is displayed on the second display area,

wherein the first display area displays the EEG having a length corresponding to a first time period, and the second display area displays the EEG in the past having a length corresponding to the first time period.

11. The vital sign display monitor as set forth in claim 10, wherein the controller includes a filter which eliminates noise from the electroencephalogram to be displayed on at least one of the first display area and the second display area.

12. The vital sign display monitor as set forth in claim 11, wherein the noise is stemmed from a cardiac potential.
