Normally, before operating the start/stop push button 72, the automatic blood pressure monitor 1 is
0 is activated, and biological information such as the blood pressure value, pulse rate, and respiration rate of the subject is automatically measured repeatedly in a fixed cycle. Next, when the start/stop push button 72 is pressed, step S1 is first executed and various initial processes are executed. In this initial processing,
For example, the recording area manual routine shown in FIG. 8 is executed to set the position and vertical and horizontal dimensions of the two-dimensional diagram recording area 20, and the full scale of the vertical axis 76 and horizontal axis 78 of the two-dimensional diagram recording area 20. The value is set.

The recording area input routine shown in FIG.
By positioning the pen 38 at the four corners of the two-dimensional chart recording area 20 and operating the setting key 73 while operating the keys 71d to 71d, the position and size of the two-dimensional chart recording area 20 are input, and the number key 69 and the setting key 73, the vertical axis 76 and the horizontal axis 7
The full scale value of 8 is input. That is, in step SNI, Ben 3 of the X-Y plotter 22
The signal for positioning 8 at the origin is sent to the X-Y plotter 22.
As a result, the ben 38 moves to the lower left corner position (Xo, Yo) in FIG.
At the same time, the contents of registers X and Y, which will be described later, are cleared to zero. In the following step SN2, the position of the upper left point P1 of the two-dimensional chart recording area 20 (X, Y
l) is done manually. This input is performed using the four direction keys 71a to 71d, that is, the right switch 71a, the left switch 71b, the upper switch 71C1 and the lower switch 71d.
is executed when the is operated. That is, in step SN2, the point position input routine shown in FIG. 9 is executed. First, in step ST1, the right switch 71
It is determined whether or not a is on, that is, is being operated,
If it is determined that the pen 38 has been operated, step ST2 is executed, and a signal for moving the pen 38 one step to the right is supplied to the X-Y plotter 22, and the pen 38 is moved one step to the right in FIG. At the same time, 1 is added to the contents of register X indicating the position of the input point in the X direction. Such operations are repeated as long as the right switch 71a is operated. If it is determined in step S'Fl that the right switch 71a is not operated, step ST3 is executed to determine whether or not the left switch 71b is operated. If the input point is being operated, step ST4 is executed, and the pen 38 is moved one step to the left in FIG. 3, and 1 is subtracted from the contents of the register Ru. If it is determined in step ST3 that the left switch 7, lb is not operated, step ST5 is executed to determine whether or not the upper switch 71c is operated. If it is operated, step ST6
is executed, the pen 38 is moved one step upward in FIG. 3, and 1 is added to the contents of register Y indicating the Y-direction position of the input point. If it is determined in step ST5 that the upper switch 71c is not operated, step ST7 is executed and the lower switch 71c is not operated.
It is determined whether or not d is being operated. If the pen 38 is operated, step ST8 is executed and the pen 38 is moved to the third
The point is moved one step downward in the diagram, and 1 is subtracted from the contents of register Y indicating the Y-direction position of the manually operated point. In this way, the right switch 71a, the left switch 71b, the upper switch 7Lc, and the lower switch 71d are operated, and the pen 38 is moved to the upper left point P of the two-dimensional diagram recording area 20.
, the setting key 73 is operated, and the judgment in step ST9 is affirmed, and step 5TIO is executed. In this step 5TIO, registers X and Y are The content is read as the position of the upper left point P1.

Returning to FIG. 8, in step SN3, the position of the lower right point P2 (X2,
Yz) is read.

In this way, the position of the upper left point P1 (XI, Yl
) and the position (Xz, Y2) of the lower right point P2 are manually operated, steps SN4 and SN5 are executed, and the position (XI, Yl) of the upper left point P, and the lower right point P
2 position (X2, Y2), the position of the lower left point P3 (XI, yz) and the position of the upper right point P4 ('
yCZ, Yl) are determined and stored, respectively. In the following step SN6, the full scale value of the horizontal axis 78 is input using the numerical keys 69 and is read by operating the setting key 73. Similarly, in step SN7, the full scale value on the vertical axis 76 is read. For example, if the total length of the horizontal axis 78 is equivalent to 3 hours, 300 is input, and the total length of the vertical axis is 20 hours.
In the case of 0 mmHg, 200 is input.

The data indicating the actual position, size, and full scale value of the two-dimensional diagram recording area 20 manually created as described above is R
1. It is written in the diagram size storage area 82 in AM68. a. In this way, the two-dimensional diagram recording area 20
Since the actual positions and dimensions of CPU that executes the routine
4 and RAM 68 correspond to recording area input means.

Then, in step SN8, each point PI, P2°P3 .
In order to check whether the entry at the position P4 has been performed correctly, in response to the operation of the confirmation key 75, move the pen 38 to the point PI.
, P3+ P2. P4. A signal for sequentially moving to the PI is output to the X-Y plotter 22. This brings Ben 38 to point P+, Pi.

P2. Since it moves while drawing a rectangle with corners P4, the operator can visually confirm the position input.

Returning to FIG. 7, in step S2, it is determined whether a signal representing biological information has been supplied from the automatic blood pressure monitor 10. If the signal is not supplied, step S2 is repeatedly executed to enter a standby state, but if the signal is supplied, step S3 is executed, and the data indicated by the input signal is read and the input time is set in the clock circuit. 70
is read based on the output signal of Next step S4
Now, based on the actual position and vertical and horizontal dimensions of the two-dimensional chart recording area 20 stored in advance in the chart size storage area 82, and the input time and data read in step S3, Determine the entry position and entry symbol. This determination method is based on the horizontal axis 7 indicating the real time.
8, a line parallel to the vertical axis 76 passing through the position corresponding to the input time is determined, and a position indicating the size of the input data is calculated on the vertical axis 76 where the full scale value is set. The position is determined on the parallel lines.

Next, in step S5, it is determined whether the entry position determined in step S4 is outside the two-dimensional chart recording area 200 frame. This determination is solely for determining whether the writing position is out of the full scale of the time axis (horizontal axis 78). Normally, the entry position is within the frame, so step S continues.
6 is executed and the signal indicating the entry position and symbol is x-
The measured values of the biological information supplied from the automatic blood pressure monitor 10 are outputted to the y-plotter 22, and the measured values of the biological information supplied from the automatic blood pressure monitor 10 are written by the X-Y plotter 22 at the positions indicated by the above-mentioned signals with the symbols indicated by the above-mentioned signals. For example, immediately after startup, symbols are written along line a in FIG. 2, and after 10 minutes, symbols are written along line b. In FIG. 2, the symbols 〉- or systolic blood pressure values and diastolic blood pressure values are shown, the symbol ◯ indicates the respiratory rate, and the symbol 〉 indicates the pulse rate. Further, a time is written near the time axis in the two-dimensional chart recording area 20 every time data is written or every predetermined number of times.

When the above steps are repeatedly executed, symbols indicating blood pressure values and other symbols as shown in FIG. 2 are sequentially written on the time axis in the two-dimensional chart recording area 20, and trends in biological information are is displayed.

If the elapsed time after startup exceeds the preset full scale time of the time axis while such a state continues, in step S5, the entry position determined in step S4 is changed to the time axis. (horizontal axis 78) is determined to be outside the full scale. In this state, step S
7 is executed, an alarm output indicating that the anesthesia recording paper 18 should be replaced is outputted, the replacement command lamp 80 is turned on, and an alarm sound is emitted from a sounding device (not shown). Next step S
In step 8, the full scale of the time axis is automatically newly set, and a new entry position is determined based on the new full scale. This new full-scale value will be the time after a period of time corresponding to the length of the time axis has elapsed from the current time.

Then, in step S9, it is determined whether the anesthesia recording paper 18 should be replaced.

This determination is made when the signal from the paper sensor 42 is once turned off and then turned on. If the anesthesia recording paper 18 is not replaced, step S9 is repeatedly executed and a standby state is entered, but if the anesthesia recording paper 18 is replaced, the steps from step 86 onwards are executed.

As described above, according to the present embodiment, the control device 16 determines the measurement time and the measured value of the automatic blood pressure monitor 10 at a predetermined location on the anesthesia record paper 18. 2D chart recording area 20
The entry position within is calculated, and a symbol indicating the measurement value is automatically entered at the entry position by the X-Y plotter 22. Therefore, the complicated and burdensome task of writing the vital information fW on the anesthesia record sheet 18 is completely eliminated, and errors in writing can be prevented.

Further, the actual position and dimensions of the two-dimensional diagram recording area 20 are input by operating the direction keys 71a to 71d, etc., and are stored in the diagram dimension storage area 82, and the biological information is displayed at a position determined based on this. Since the symbols are written, '1/j' may be caused by misprinting, variations in the position of the two-dimensional diagram recording area 20 due to expansion and contraction of the anesthesia recording paper 18, misalignment of the anesthesia recording paper 18 on the mounting table 24, etc.
Even if the two-dimensional chart recording area 20 is shifted on the table 2, the data will be accurately written in the two-dimensional chart recording area 20. Therefore, in this embodiment, the anesthesia recording paper 18 may be appropriately placed on the mark line drawn on the mounting table 24-1, and the positioning plate 40 is not necessarily required.

Moreover, the anesthesia recording paper 18 is
4, even when the biological information is being automatically entered, other record items such as the name of the anesthetic administered and the time of administration can be handwritten in the designated areas on the anesthesia record sheet 18. It has the advantage of being able to be filled out.

Further, according to the present embodiment, when the entry position of the symbol exceeds the full scale of the time axis (horizontal axis 78) in the two-dimensional chart recording area 20, an alarm is automatically output and a new anesthesia recording paper 18 is written. Since the symbol is entered after the change, there is an advantage that the entry on the anesthesia record sheet 18 can be performed accurately.

Next, another embodiment of the present invention will be described. In the following description, parts common to those in the above-described embodiments are designated by the same reference numerals, and the description thereof will be omitted.

First, step SE1 is executed and the low reencoder 8
4, it is determined whether or not a positive pulse in the X direction has been output. If this determination is affirmative, step SE2 is executed and 1 is added to the contents of register X. Steps SEI and SE2 are executed every time a positive pulse is output from the low reencoder 84. Step SE
If the determination in I is negative, step SE3 is executed and it is determined whether or not a negative pulse in the X direction is output from the low reencoder 84. If this judgment is affirmative, step SE4 is executed and the register
1 is subtracted from the contents of . Next, step SE5 is executed and it is determined whether or not the low reencoder 86 outputs a positive pulse in the Y direction. If this determination is affirmative, step SE6 is executed and 1 is added to the contents of register Y. If the determination in step SE5 is negative, step SET is executed and it is determined whether or not a negative pulse in the Y direction has been output from the low reencoder 86. If this judgment is affirmed, Nihasten'7''SE8 is executed and 1 is obtained from the contents of register Y.
is subtracted. By manually operating the pen 38 in this manner, the upper left point P of the two-dimensional diagram recording area 20 is
1 (X+, Y+), the setting key 73 is operated, so the judgment in step SE9 is affirmed and step 5EIO is executed. In step 5EIO, register Y and the contents of register Y are read as the position of left hit point P1.

Therefore, in this embodiment, the rotary encoder 84.
86, the setting key 73, the ROM 66 in which the recording area entry turntable of FIG. 8 is stored, the CPU 64 and RAM 68 that execute the recording area input routine of FIG. 8, etc. correspond to the recording area input means.
