Abstract

A vital sign display device and method which allows a vital sign to be checked easily is provided. A vital sign item name is displayed at the center of a circle radar (50). The circle part of the circle radar (50) is colored in gray, for example, at the beginning of the measurement. An indication point moves clockwise in the circle radar (50) as the measurement time proceeds. Green is displayed while VPCs (ventricular premature contractions) do not occur, and red is displayed when VPCs occur.

Claims

1. A vital sign display device for displaying a vital sign, comprising:

means for obtaining a biological signal;

means for determining whether living body condition represented by the biological signal is abnormal or not, which is based on the obtained biological signal; and

means for displaying a vital sign obtained from the biological signal, that allows to discriminate whether the condition is abnormal or not, which is based on the determination results from the determining means, wherein the vital sign is arranged in time series that allows to provide history of the vital sign.

4. The device according to claim 1, wherein the vital sign is displayed so as to follow a circular shape according to time series of the vital sign.

6. The device according to claim 1, further comprising means for selecting display styles, wherein the display style selecting means determines entire display period corresponds to display area for the vital sign by correlating with measurement period of the vital sign.

7. The device according to claim 1, further comprising means for displaying item name of vital sign, wherein the vital sign item name displaying means displays the item name by relating the item name to the displayed vital sign.

8. The device according to claim 1, wherein the display style of vital sign is changed to another style when the abnormal condition occurs.

9. The device according to claim 1, wherein the vital sign comprises at least an item of VPC (ventricular premature contraction), HR (heart rate), QT interval, or SpO₂ value (oxygen saturation in blood).

2. A computer readable medium having stored thereon the computer program for a vital sign display device that displays a vital sign, wherein the program is implemented in a computer and capable of causing the computer to perform:

means for obtaining a biological signal;

means for determining whether living body condition represented by the biological signal is abnormal or not, which is based on the obtained biological signal; and

means for displaying a vital sign obtained from the biological signal, that allows to discriminate whether the condition is abnormal or not, which is based on the determination results from the determining means, wherein the vital sign is arranged in time series that allows to provide history of the vital sign.

3. A vital sign display device for displaying a vital sign, comprising:

means for displaying a vital sign, obtained from the biological signal or signal generated from the biological signal, that allows to discriminate whether living body condition represented by the signal is abnormal or not, wherein the vital sign is arranged in time series that allows to provide history of the vital sign.

5. A vital sign display device for displaying a vital sign, comprising:

means for obtaining a biological signal;

means for determining whether living body condition represented by the biological signal is abnormal or not, which is based on the obtained biological signal; and

means for displaying a vital sign obtained from the biological signal, that allows to discriminate whether the condition is abnormal or not, which is based on the determination results from the determining means, wherein the display is executed by moving a display object in the direction to draw a circular shape according to time series of the vital sign.

10. A vital sign display device for displaying a vital sign, a central processing unit (CPU) of the vital sign display device is to execute the procedures of:

obtaining a biological signal;

determining whether living body condition represented by the biological signal is abnormal or not, which is based on the obtained biological signal; and

instructing to display a vital sign obtained from the biological signal, that allows to discriminate whether the condition is abnormal or not, which is based on the determination results, wherein the vital sign is arranged in time series that allows to provide history of the vital sign.

11. A vital sign display device for displaying a vital sign, a central processing unit (CPU) of the vital sign display device is to execute the procedures of:

instructing to display a vital sign, obtained from a biological signal or a signal generated from the biological signal, that allows to discriminate whether living body condition represented by the signal is abnormal or not, wherein the vital sign is arranged in time series that allows to provide history of the vital sign.

12. A vital sign display device for displaying a vital sign, a central processing unit (CPU) of the vital sign display device is to execute the procedures of:

obtaining a biological signal;

determining whether living body condition represented by the biological signal is abnormal or not, which is based on the obtained biological signal; and

instructing to display a vital sign obtained from the biological signal, that allows to discriminate whether the condition is abnormal or not, which is based on the determination results, wherein the display is executed by moving a display object in the direction of following a circular shape according to time series of the vital sign.

13. A vital sign displayed object representing a vital sign, wherein the vital sign displayed object represents a vital sign obtained from a biological signal, that allows to discriminate whether living body condition represented by the biological signal is abnormal or not, wherein the vital sign is arranged in time series that allows to provide history of the vital sign.

14. A method for displaying a vital sign comprising the steps of:

obtaining a biological signal;

determining whether living body condition represented by the biological signal is abnormal or not, which is based on the obtained biological signal; and

displaying a vital sign obtained from the biological signal, that allows to discriminate whether the condition is abnormal or not, which is based on the determination results, wherein the vital sign is arranged in time series that allows to provide history of the vital sign.

15. A method for displaying a vital sign comprising the steps of:

obtaining a biological signal;

determining whether living body condition represented by the biological signal is abnormal or not, which is based on the obtained biological signal; and

displaying a vital sign obtained from the biological signal, that allows to discriminate whether the condition is abnormal or not, which is based on the determination results from the determining means, wherein the display is executed by moving a display object in the direction of following a circular shape according to time series of the vital sign.
