Further, although the example in which the floppy disk device 150 is provided on the front side of the device has been described, it may be provided on a side surface of the device, for example, at a position below the operation panel B250b.

The control of the present embodiment having the above configuration is shown in FIG.
This will be described below with reference to the flowchart (B).

First, in step S1, it is determined whether or not analysis recording of electrocardiogram information or the like is to be performed. If analysis recording is not to be performed, the process proceeds to step S10, and it is determined whether or not recording of electrocardiogram information is to be performed. If the electrocardiogram recording is not to be performed, the process proceeds to step S22, where it is determined whether or not to perform the host transfer process of reading out the electrocardiogram information and the like previously collected and recorded on the floppy disk device and transferring the information to the connected host 350. Judge. If the host transfer process is not to be performed, the process proceeds to step S23,
Check whether to set the processing mode. If the setting of the processing mode is not performed, the corresponding processing is executed in step S24.

When collecting electrocardiogram information and the like in the apparatus according to the present embodiment, first, the processing mode of the apparatus according to the present embodiment is confirmed with reference to an initial display screen of the display unit 200 and the like. That is, it is checked whether the child is in the processing mode for school child screening when a child screening for school children is to be performed, or whether it is in the normal processing mode otherwise. If the schoolchild screening is not in the schoolchild screening processing mode, the processing mode setting key on the operation panel 250 is input to set the processing mode to the schoolchild screening processing mode. When the processing mode setting key is input, the process proceeds from step S23 in FIG. 3 (B) to step S50 to set a processing execution mode according to the mode input. Then, it instructs the external input control unit 30 to set the lead selector 32 to select an electrocardiographic signal to be output from the input electrocardiographic signal according to the processing mode. For example, in the case of the normal processing mode, the standard 12-lead ECG signal is set to be selectively output, and in the case of the schoolchild examination processing mode, the omitted 4-lead ECG signal (for example, I, aV _F , V ₁₎ , V ₆ ) are set to be selected and output. Then, the process returns to step S1. In this embodiment,
It is also possible to select the standard 12-lead electrocardiogram signal in the schoolchild examination processing mode and set the analysis process to the schoolchild analysis mode. In this case, an instruction is input to further perform the schoolchild 12 guidance processing mode.

In addition, since this processing mode is not frequently changed, the setting of the processing mode is not performed by key input from the operation panel 250, but is provided, for example, as a key with a cover on the side of the housing so that it cannot be easily operated. A situation in which the processing mode is incorrect may be prevented.

On the other hand, if an analysis record is to be made, step S1
Proceeding to step S2, the electrocardiogram signal collecting electrode portion of the guiding cord 190a or the guiding cord 190b connected to the guiding cord connector 191 and the microphone for collecting the heart sound signal are attached to the measurement site of the subject. In the present embodiment, there are two induction cord connectors 191. When information collection and inspection by the induction cord connected to one connector is completed, inspection is immediately performed using the induction cord connected to the other connector. Can switch. For this reason, many tests can be digested in a short time, and the efficiency of screening can be improved.
Attachment of an electrode to a subject is an important technique for recording an electrocardiogram. However, since this electrode attachment technique is known, detailed description thereof will be omitted.

Since the measurement preparation is completed, the mode key of the operation panel unit A250a is pressed and input in step S3, the analysis mode is set, and the analysis lamp is turned on. At this time, the connector for performing the analysis process is selected from the two induction code connectors 191 at the same time. Then, the process proceeds to step S4, where the subject information is input.

In the present embodiment, in the case of the processing mode for schoolchild screening, as the subject information, “survey table: 2 digits”, “school number: 6”
Digits "," school year / age: 2 digits "," group: 2 digits "," sex: male /
Woman "," Subject identification number (ID number): 3 digits "," systolic and diastolic blood pressure: 3 digits / 3 digits "," height: 3 digits "," weight: 3 "
Digits "and" obesity degree: 3 digits ".

In the case of the normal processing mode mainly for adults, "personal history: 1 digit", "organization number: 6 digits", "age: 2 digits", "sex: male / female", "test Patient identification number: 6 digits, systolic and diastolic blood pressure: 3 digits / 3 digits, height: 3 digits, weight: 3
Digits "," obesity degree: 3 digits ", etc.

When detecting the subject information input via the operation panel interface 22, the CPU 1 stores the detected subject information in the RAM3.
Save inside. It should be noted that “height”, “weight”, “systolic blood pressure value and diastolic blood pressure value” and the like are input as much as possible.
When these items are input, the reliability of the analysis result of the analysis process described later is further improved.

In a succeeding step S5, the guidance selection key of the operation panel A120a is input, and the biological information collecting process by the CPU 1 is started. CP
U1 proceeds to the process of step S6 when this guidance selection key is input, and the guidance code connector 19 selected in step S3.
The collected data on the 1 side is the guidance selector 32 and the filter processing unit 33
The digital signal is sent to the A / D converter 36 via the, and is converted into a digital signal here and taken into the CPU 1. CPU1 converts this data into RA
The information is sequentially recorded in M3 and sent to the display interface 21 to be displayed on the display unit 200 in real time.
Here, the electrocardiogram waveform or the like being measured is checked, and it is checked whether or not the electrode section and the like are correctly attached to the measurement site.
If there is an abnormality in the electrocardiogram waveform or the like, the processing from step S2 is performed again.

When the confirmation of the ECG waveform is completed, the process proceeds to step S7, and the review key is input. When the review key is input, the CPU 1 proceeds to step S8 and presses the review key.
The electrocardiogram information and the measured heart sound information 10 seconds ago (at the time of the 12th lead) or 8 seconds ago (at the time of the 4th lead) are analyzed in consideration of the subject information previously input. With this review function, an appropriate ECG can be selected and analyzed while monitoring the ECG on the display unit 200.

Then, in step S9, the analysis result is written into a predetermined area of the floppy disk 160 mounted on the floppy disk device 150 together with the electrocardiogram information and heart sound information to be analyzed, following the previous analysis result, and the printer interface. Printing is performed from the thermal printer 300 via the ace 27. Then, the process returns to step S1 to prepare for the next examination.

Output examples of the analysis results are shown in FIGS.

FIG. 4 (A) is an abbreviation 4 in the schoolchild screening processing mode.
FIG. 4 (B) shows the electrocardiogram and the analysis result, and FIG. 4 (C) shows the standard 12-lead electrocardiogram and the analysis result. In addition, in the standard 12 lead or the like, in addition to the above output, a dominant waveform can be displayed.

On the other hand, when the electrocardiogram recording mode is selected, the process proceeds from step S10 to step S21 and subsequent steps, and the electrocardiogram waveform recording process is performed. In this ECG waveform recording process,
Steps S12 to S17 are the same processing as steps S2 to S7 of the analysis processing described above. In the subsequent step S18, the electrocardiogram information and the measured heart sound information 10 seconds before (when lead 12) or 8 seconds before (when lead 4) the review key was pressed are read out from the RAM 3, and the floppy disk device is read.
The data is written in a predetermined area of the floppy disk 160 mounted on the printer 150 following the analysis result and printed out from the thermal printer 300 via the printer interface 27. Then, the process returns to step S1 to prepare for the next examination.

In this case, each of the waveforms shown in FIGS.
Of the analysis result output, only the waveform excluding the analysis result column is output and recorded.

Further, the floppy disk medium 160 on which the examination data is written is set in the floppy disk device 150, and when the host transfer process is selected, the process proceeds from step S22 to step S30, where the examination data is written. A read mode in which the execution processing mode is set to a host transfer mode for reading the examination data from the floppy disk 160 and transferring it to the host 350 by, for example, setting the floppy disk medium 160 in the floppy disk device 150. Enter the setting key. Upon detecting this input key, the CPU 1 reads various kinds of information on the subject stored in the floppy disk medium 160 according to the processing mode in the following step S31. Then, the data read in step S32 is
Transfer to 50. Then, in the following step S33, it is checked whether or not all the examination data has been read from the floppy disk 160 and transferred to the host 350. If there is any remaining examination data, the procedure returns to step S31 to read the next examination data. To the host 350. When all the examination data is transferred in this way, the process is terminated and the process returns to step S1, for example, by setting the floppy disk medium 160 in which the next examination data is written to the floppy disk device 150, or the like. And waits for the host transfer process to be specified.
