DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a biological information processing apparatus and a biological information display control method provided with a display means capable of displaying waveforms of information collected from a living body in a time-series manner. The present invention relates to an apparatus and a biological information display control method.

[0002]

2. Description of the Related Art An electrocardiogram (ECG) is widely used for finding and verifying the symptoms of various heart patients, and the accuracy of the electrocardiogram diagnosis has been greatly increased with the development of electrocardiographs. In conventional clinical medicine, an electrocardiogram measured by an electrocardiograph is printed and recorded on a recording paper to confirm a change in a waveform, and is used for finding and treating a heart disease.

[0003] In addition, with the development of electronic technology, signal processing technology has advanced, and an LCD display device has been provided. The ECG information is input, an ECG waveform is displayed on an LCD display screen, and a living body used for monitoring the condition of a subject. Information monitoring devices have also appeared.

[0004] The display of the electrocardiogram waveform displayed on the display screen of this type of LCD display device, for example, displays the waveform sequentially from the left to the right of the display screen, and displays the electrocardiogram waveform from the left end again when displayed to the right end. It is configured as
At that time, the previously displayed electrocardiogram waveform was updated and updated to a new electrocardiogram waveform while being displayed.

A blank portion is provided between the latest waveform display portion and the past waveform to indicate which waveform is the latest display waveform. The blank portion was moved from left to right so that it was possible to visually recognize which portion of the display was the latest displayed electrocardiogram waveform portion. Then, when an abnormality is confirmed in the displayed waveform, the display state of the waveform can be fixed to confirm the abnormal waveform.

[0006]

However, in the conventional apparatus, if the display state is fixed in order to confirm the electrocardiogram, the leftmost waveform is on the left side of the blank portion and the most recent waveform is on the right side of the blank portion. However, the order of the waveforms is not continuous, and it is difficult to grasp the temporal order, which makes it difficult to make a determination. In particular, in the case of displaying over a plurality of stages, since the temporal context extends up and down, it is even more difficult to grasp the context of the waveform.

[0007]

SUMMARY OF THE INVENTION The present invention has been made for the purpose of solving the above-mentioned problems, and has the following arrangement as one means for solving the above-mentioned problems.

That is, in a biological information processing apparatus having display means for displaying biological information, an input means for inputting information collected from a living body, and at least a part of the information collected from the living body input by the input means are chronologically displayed. Waveform display means for displaying a waveform on the display, the waveform display means, when displaying the input biological information waveform in the waveform display area of the display means, after initializing the display area, the waveform display tip from the initial display position When the position is moved, the waveform is displayed in time series, and when the display is moved to the end of the time series display area, the waveform display is performed while the waveform display tip position is moved from the initial display position after initializing the time series display area again. It is characterized by

In the present embodiment, when an electrocardiogram waveform of one lead selected in advance is displayed in the electrocardiogram display area 200 on the display screen, first in step S1, a memory area corresponding to the electrocardiogram display area of the video memory 6 is set. Clear and initialize the display state of the electrocardiogram display area 200 on the display screen.

Subsequently, in step S2, an ECG waveform is drawn in a corresponding area of the video memory 6 so as to sequentially display the ECG waveform rightward from the left end of the uppermost display area 202 of the video memory 6. Then, in step S3, it is determined whether or not the electrocardiogram waveform has been displayed up to the right end of the uppermost display area 202. If the right end has not yet been displayed, the process proceeds to step S4, and it is determined whether or not an instruction to end the display and shift to another display scene has been issued. If an instruction to shift to another display scene has been issued, the display control ends and the display control shifts to the indicated display control.

Rewrite to an area corresponding to 30. As a result, the display waveform of the uppermost stage 202 is shifted and displayed on the second stage 203.
Then, in step S7, the drawing data in the area corresponding to the uppermost display area 202 of the video memory 6 is cleared, and the process returns to step S2, where the electrocardiogram waveform is sequentially shifted rightward from the left end of the uppermost display area 202 of the video memory 6. Is displayed in the corresponding area of the video memory 6 so as to display.

If an instruction to stop the display state of the display screen is given during the above display control, the video memory 6
Is stopped, and the display state is fixed. In addition,
Also in this case, since the latest electrocardiogram display waveform is always displayed at the top, it is possible to easily recognize before and after the time of the display waveform. Also, since the top display waveform is not overwritten but only the newest display waveform is displayed,
The latest display timing can be easily recognized.

As described above, according to the present embodiment, the latest electrocardiogram waveform is always displayed at the top, and the waveform that is temporally retroactive is displayed as it goes down, so that the displayed electrocardiogram waveform is displayed. Can be clearly recognized before and after the time. For this reason, as in the past, it was not possible to know which of the electrocardiogram waveforms displayed on the display screen was the latest waveform without constantly watching the screen,
The redisplayed waveform portion can be easily specified at a glance of the screen.

As described above, according to the present invention, the most recent electrocardiogram waveform is always displayed at the top, and the waveform that goes back in time is sequentially displayed as it goes down, so that the displayed electrocardiogram waveform is displayed. Time can be clearly recognized before and after.
