The superimposing circuit 26 superimposes the biometric information image signal on the endoscopic image signal supplied from the video amplifier 24 to the color CRT 28, so that the color CRT 2 is obtained.
At 8, the biometric image is displayed together with the endoscopic image. The superimposing circuit 26 is a well-known circuit used when, for example, a numerical value indicating a channel selected on a TV screen and a numerical value indicating time are displayed in a superimposed manner on a TV image. Is marketed as.

The voice storage ROM 62 stores a series of code signals corresponding to a plurality of voices. When the voice output switch 70 is switched to the voice output side, the voice synthesis circuit 60 is used. Designates any one of the plurality of types of voices according to a signal from the electronic control unit 56, extracts a series of code signals SC corresponding to the designated voices, and sequentially supplies them to the D / A converter 64. At the same time, a clock signal SK having a predetermined clock frequency is generated from a plurality of preset clock frequencies according to a command from the electronic control unit 56, and is supplied to the D / A converter 64. In the D / A converter 64, the code signal SC is converted into an analog signal having a size corresponding to the code signal SC for each cycle of the clock signal SK, so that a voice signal having a pitch corresponding to the frequency of the clock signal SK (an analog signal). ) Is generated and output to the speaker 68 functioning as an audio output unit via the audio amplifier 66. The voice synthesis is based on so-called pulse code modulation. In this embodiment, the voice synthesizing circuit 60, the ROM 62, and the D / A converter 64 function as a voice signal converting means for converting into a voice signal which is an analog signal waveform representing biological information.

The portable vibration generator 61 is composed of, for example, an eccentric rotating body in which the center of gravity is unevenly distributed, and a motor for rotationally driving the eccentric rotating body, and informs the wearer of abnormal biological information. Therefore, a vibration of a relatively low frequency of several Hz to several tens of Hz is generated according to a signal from the electronic control unit 56. In this embodiment, the portable vibration generator 61 functions as a portable vibration generator.

FIG. 2 is a flow chart for explaining the main part of the control operation of the electronic control unit 56. In the figure,
At step (hereinafter, step is omitted) SA1, input signals from the blood pressure measurement device 50, the blood oxygen saturation measurement device 52, and the heart rate detection device 54 are read. Continued SA
In 2, it is determined whether or not it is within the preset display period of the biometric information. The display period of the biometric information is a time ratio that does not hinder the observation of the endoscopic image displayed on the color CRT 28, and is a preset period so that a change in the condition of the biological body can be quickly known. For example, it is a period set for each cycle of about ten and several seconds to a fraction of the cycle.

If the determination at SA2 is negative, then SA
4 or less is executed, but if the result is affirmative, in SA3, the blood pressure value BP, the blood oxygen saturation level OX, and the numerical values indicating the heart rate HR are output from the electronic control device 56, and the biometric information image indicating these numerical values is displayed. The biometric information image generation circuit 58 generates the biometric information image signal representing the biometric information image in the superimposing circuit 26, and the biometric information image signal representing the endoscopic image is superimposed on the biometric information image signal.
For example, as shown in FIG. 3, the biometric information image G _S is displayed so as to overlap the right end portion of the endoscopic image G _N. The upper part of the biological information image G _S of FIG. 3 is a number indicating the systolic blood pressure value BP _SYS and the minimum blood pressure value BP _DIA , the middle part is a number indicating the blood oxygen saturation level OX, and the lower part is a number indicating the heart rate HR. When the biometric information has a normal value, the endoscopic image G _N is displayed in a relatively small character size or in a relatively light inconspicuous color so as not to interfere with the display of the endoscopic image G _N.

Further, when the voice output switch 70 is operated to the voice output side, at the same time as the above, the blood pressure value BP, the blood oxygen saturation level OX, and the heart rate HR are displayed from the electronic control unit 56. Are output to the voice synthesizing circuit 60, and the numerical values of the biometric information are output only once by voice. If those numerical values are normal values, the speech synthesis circuit 60 outputs D

Then, it is determined whether or not the blood pressure value BP, the blood oxygen saturation level OX, and the heart rate HR are abnormal values. This determination is made based on whether or not the preset normal range of each biometric information is exceeded. If this determination in SA4 is denied, this routine is ended, but if the determination is affirmative, in SA5 corresponding to the abnormal value display means, the abnormal display of the biological information for which abnormality has been judged is preferentially executed by the image. To be done. As the abnormal display of the image, compared to the case where it is within the normal range, the enlarged display of the biometric information display character, the blinking display of a relatively short period, or the display in a dark color is performed. Or, it is displayed in an abnormal color having a high contrast with respect to the background such as red, orange and yellow. At the same time, the portable vibration generator 61 generates vibration according to the drive signal from the electronic control unit 56.

When the voice output switch 70 is switched to the voice output side, the voice abnormality display is simultaneously performed. That is, from the voice synthesis circuit 60 to D
The frequency of the clock signal SK supplied to the / A converter 64 is changed to a high value, and the blood pressure value BP and the blood oxygen saturation O
X, the pitch of the voice notifying the biometric information value, which is a numerical value indicating the heart rate HR, is increased, such as a female voice. Therefore, in this embodiment, the SA5 corresponds to the pitch changing means.

As described above, according to this embodiment, the blood pressure value BP and the blood oxygen level are measured by the blood pressure measuring device 50, the blood oxygen saturation measuring device 52 and the heart rate detecting device 54 which function as the biological information detecting means. When the biometric information such as the saturation OX and the heart rate HR is detected, it is determined whether or not the biometric information is an abnormal value exceeding a preset normal range by SA4 corresponding to the abnormal value determination means, and the abnormality is detected. If it is determined to be a value, SA5 corresponding to the pitch changing means
Voice synthesis circuit 6 functioning as the voice signal conversion means
0, the pitch of the voice signal converted by the D / A converter 64 is changed, and thus the pitch of the voice display of the biological information output from the speaker 68 is changed. Therefore, even a medical worker who focuses his or her attention on medical work can clearly recognize an abnormality in biometric information, while the patient does not feel any anxiety even if the pitch of the voice output of biometric information is changed. .

Further, according to the present embodiment, when it is judged by SA4 corresponding to the abnormal value judging means whether or not the biometric information is an abnormal value exceeding the preset normal range, the portable vibration generating apparatus. Since 61 generates vibration in accordance with the drive signal from the electronic control device 56, even if a medical worker focuses his or her attention on medical work by carrying the portable vibration generator 61, even if the medical worker carries out biological information While the abnormality can be more clearly recognized, the patient does not feel that the portable vibration generator 61 is vibrating, and therefore does not feel any anxiety.

Portable vibration generator 61
Although both and are provided, the object of the present invention can be achieved even if only one of them is provided.

Further, in the above-mentioned embodiment, the speaker 68 for outputting the voice indicating the numerical value of the biological information is provided, but instead of this, the head or ear of the worker such as a headphone or an earphone. There is no problem even if a portable type that can be mounted on is used. When a portable voice output means such as a headphone or an earphone is provided, an operator, that is, a medical staff can be made to more clearly recognize the abnormality of the biological information, while Since the voice output is hard to reach, the patient's anxiety is further alleviated.

The biometric information in the above embodiment is
