Description

TECHNICAL FIELD The present invention relates to an apparatus for automatically writing biometric information on a recording paper.

2. Description of the Related Art A two-dimensional diagram in which biological information such as blood pressure, pulse rate, and respiration rate is provided at a predetermined location on a recording paper in order to record changes in the condition of the living body during operation of the living body or during monitoring in the intensive care unit. It is recorded over time with a predetermined symbol in the recording area. Such recording work is usually performed manually by a doctor or a nurse.

Problems to be Solved by the Invention However, in such a conventional case, the work of filling the value displayed on the measuring device for measuring biological information in the recording area of the recording paper is relatively complicated, Due to the difficulty of securing the number of specialists, the burden is relatively heavy in a busy hospital, and there is a possibility that the filling of biometric information may not be executed accurately.

Therefore, a biometric information automatic device including a biometric information measuring device that repeatedly measures biometric information such as blood pressure, pulse rate, and respiration rate, and a recording device that automatically writes a symbol representing the measured biometric information on a recording sheet An entry device has been proposed. For example, the anesthesia process recording device described in Japanese Patent Laid-Open No. 59-62030. According to such a device, the biometric information measured by the biometric information measuring device is automatically written on the recording paper. Therefore, the complicated and burdensome work of writing the biometric information on the recording sheet is completely eliminated, and an error in the entry is prevented.

However, if a recording paper in which a two-dimensional diagram recording area is preliminarily printed at a predetermined location (recording paper conventionally used in a hospital) is used as a recording paper used in such a biometric information automatic filling device, medical-related Although the person feels little resistance and is convenient in management, in such a case, when the value measured by the biological information measuring device is entered by the recording device in the two-dimensional diagram recording area, There is a drawback that the two-dimensional diagram recording area cannot be accurately written due to variations in the position of the two-dimensional diagram recording area due to print misalignment and expansion / contraction of the recording sheet, and placement deviation of the recording sheet on the mounting table.

Means for Solving Problems The present invention has been made in the background of the above circumstances, and its gist is to provide at least one of biological information such as blood pressure, pulse rate, and respiratory rate of a living body. A two-dimensional diagram recording area that is repeatedly measured and a symbol that represents the measured biological information is represented by a printed line printed on a grid surrounded by a vertical axis and a horizontal axis at regular intervals at predetermined locations on the recording paper. A biometric information automatic filling device that automatically fills in
(A) a biological information measuring device for measuring the biological information,
(B) A mounting table provided with a mounting table for mounting the recording paper, and a carriage for mounting a pen for recording biometric information on the recording paper and moving the pen relative to the recording paper. A recording device for writing the biometric information on the upper recording paper, (c) a printed line detection device provided on the carriage for detecting a printed line representing the two-dimensional diagram recording area, and (d) preset By moving the carriage relative to the recording paper in the direction described above, the position of the two-dimensional diagram recording area provided at a predetermined position on the recording paper placed on the mounting table is Recording area detection means for calculating from a position of a print line printed on a grid surrounded by a vertical axis and a horizontal axis at regular intervals detected by the print line detecting device and storing the print area, (e) the biological information measurement Measured by the device From the measurement time and the value of the biometric information measured by the biometric information measuring device, the entry position in the two-dimensional diagram recording area stored by the recording area detecting means is calculated, and a symbol representing the biometric information is added to the entry position. And a control device for making the recording device fill in.

By doing so, the position of the two-dimensional diagram recording area in which the symbol representing the biological information is automatically entered by the recording device is
The recording area detection means moves the carriage relative to the recording paper in a preset direction, so that the grid surrounded by the vertical axis and the horizontal axis at constant intervals detected by the printed line detection device. Since it is calculated from the position of the print line printed on, the position of the two-dimensional diagram recording area varies due to printing misalignment or expansion / contraction of the recording paper, and the placement of the recording paper on the mounting table is misaligned. Even in this case, the information is accurately written at a predetermined position in the two-dimensional diagram recording area.

Moreover, since the recording paper is designed to be placed on the placing table of the recording apparatus, the name and time of administration of the medicine administered, or the medical treatment applied to the living body, even during the automatic filling of the biological information.

Supply.

Hereinafter, the operation of the control device 16 will be described. The flow chart shown in FIG. 8 shows a control routine executed by pressing the start / stop push button 72. This control routine is stopped by the start / stop push button 72 being pressed next. To be done.

Normally, the automatic sphygmomanometer 10 is operated before the start / stop pushbutton 72 is operated.
Is activated, and biological information such as the blood pressure value, pulse rate, and respiration rate of the measurement subject is automatically and repeatedly measured in a fixed cycle. Next, when the start / stop push button 72 is pressed, various initial processes are executed by first executing step S1. In this initial processing, for example, a recording area detecting routine shown in FIG. 9 is executed to automatically set the position of the two-dimensional chart recording area 20 and its vertical and horizontal dimensions.

The recording area detection routine shown in FIG. 9 is for automatically detecting the position and size of the two-dimensional diagram recording area 20 by scanning the anesthesia recording paper 18 with the optical sensor 82 provided in the carriage 34. It is a thing. First, step SK1
A signal for positioning the pen 38 of the XY plotter 22 at the origin is supplied to the XY plotter 22 so that the carriage 34 moves to the position (X ₀ , Y ₀ ) in the lower left corner of FIG. It is moved and the contents of register X and register Y are cleared to zero. The register X or the register Y is incremented by one each time the carriage 34 moves in one step in the X direction or the Y direction in the positive direction, and is subtracted each time the carriage 34 moves in the negative direction. In the following step SK2, the carriage 34 is moved to the predetermined position (X ₀ , Y _c ) so as to be located at the center of the two-dimensional chart recording area 20 in the Y direction, and the carriage 34 is moved to the X position by executing the following step SK3. Can be moved in the direction. In this process the optical sensor
82 outputs a pulse signal corresponding to the line printed on the anesthesia recording paper 18, but since the grid at a constant interval (for example, 3 mm) is printed in the two-dimensional diagram recording area 20, the two-dimensional diagram While passing through the recording area 20, pulse signals are output at regular intervals. In step SK4 above, this phenomenon is used, and the position (X ₁ , Y _c ) when the earliest one of the pulse signals at the above-mentioned constant intervals occurs and the position (X _1
2 , Y _c ) are stored.

In step SK4, for example, the frontmost final pulse detection routine shown in FIG. 10 is executed. In step SP1, it is determined whether the pulse signal from the optical sensor 82 is generated. When the pulse signal is not generated, step SP1 is repeatedly executed to enter the standby state. When it is determined that the pulse signal is generated, step SP2 is executed and the position of carriage 34 at the time of generation is stored. The position of this carriage 34 is such that the contents of the registers X and Y are in the X direction and Y.
Read as directional position. In the following step SP3, an algorithm for detecting the first equidistant pulse and the last equidistant pulse is executed. This algorithm detects the earliest and final ones of a series of groups in which the pulse generation positions stored in step SP2 are equidistant. In step SP4, it is determined whether or not the final equidistant pulses have been detected. If it is determined that it is not detected, step SP1 and subsequent steps are executed again, but if it is determined that it is detected, step SP5 is executed and the position (X ₁ ,
Y _c ) and the position (X ₂ , Y _c ) of the carriage 34 at the time of generation of the last equally-spaced pulse are stored.

Returning to FIG. 9, the following step SK5 is executed, so that the carriage 34 is located at a predetermined position (X _c , Y ₀ ) so as to be located at the center of the two-dimensional chart recording area 20 in the X direction.
Then, the carriage 34 is moved in the Y direction by executing step SK6. Then, in step SK7, like step SK4, the position (X _c , Y ₁ ) when the earliest pulse signal from the optical sensor 82 is generated and the position (X _c , Y ₁ ) when the last pulse signal is generated ( X _c , Y ₂ )
And are remembered.

Then, in step SK8, from the respective positions (X ₁ , Y _c ), (X ₂ , Y _c ), (X _c , Y ₁ ), (X _c , Y ₂ ) stored as described above, two-dimensional Based on the assumption that the vertical axis 76 and the horizontal axis 78 of the chart recording area 20 are parallel to the Y direction and the X direction, respectively, the position of the upper left point P ₁ of the two-dimensional chart recording area 20 (X ₁ , Y ₁ ), The position of the upper right point P ₂ (X ₂ , Y ₂ ), the position of the lower left point P ₃ (X ₁ , Y ₂ ), and the position of the upper right point P ₄ (X ₂ , Y ₁ ) are respectively determined and these are determined by the RAM 68. It is stored in the diagram size storage area 81 provided therein. The position and size of the two-dimensional diagram recording area 20 are represented by these points P ₁ , P ₂ , P ₃ , P ₄ .
Therefore, in the present embodiment, the optical sensor 82 corresponds to the printed line detection device, the ROM 66 in which the recording area detection program of FIG. 9 is stored, and the C for executing the recording area detection routine of FIG.
The PU 64 and the RAM 68 correspond to the recording area detecting means.

Returning to FIG. 8, in step S2, it is determined whether or not the signal indicating the biological information from the automatic blood pressure monitor 10 is supplied. When the signal is not supplied, step S2 is repeatedly executed to enter the standby state.When the signal is supplied, step S3 is executed, the data indicated by the input signal is read, and the input time is set to the clock circuit. Read based on 70 output signals. In a succeeding step S4, a two-dimensional chart recording area previously stored in the chart dimension storing area 81.
The entry position and entry symbol are determined in the two-dimensional diagram recording area 20 based on the actual position of 20 and the vertical and horizontal dimensions thereof, and the input time and data read in step S3.
This determination method determines the line parallel to the vertical axis 76 that passes through the position corresponding to the input time on the horizontal axis 78 indicating the real time, and the input data on the vertical axis 76 where the full scale value is set. Is calculated, and this position is determined on the parallel lines. In addition,
The full-scale values on the vertical axis 76 and the horizontal axis 78 are stored in advance, and when the writing position is determined, if there is a displacement between the detection position of the optical sensor 82 and the writing position of the pen 38, This deviation is taken into consideration.

Next, in step S5, it is determined whether or not the entry position determined in step S4 is outside the frame of the two-dimensional diagram recording area 20. For this judgment, the entry position is exclusively on the time axis (horizontal axis 7
It is to judge whether it is out of the full scale of 8). Since the entry position is usually within the frame, the subsequent step S6 is executed, a signal indicating the entry position and the symbol is output to the XY plotter 22, and the measurement of the biological information supplied from the automatic sphygmomanometer 10 by this XY plotter 22. The value is written in the position indicated by the signal with the symbol indicated by the signal. For example, immediately after starting, a signal is written along the line a in FIG. 2, and after 10 minutes, a symbol is written along the line b. The second
In the figure, the symbol>-<indicates the systolic blood pressure value and the diastolic blood pressure value, the symbol ◯ indicates the respiratory rate, and the mark indicates the pulse.
Further, the time is written in the vicinity of the time axis in the two-dimensional diagram recording area 20 every time data is entered or every predetermined number of times.

When the above steps are repeatedly executed, a symbol indicating a blood pressure value or another symbol as shown in FIG. 2, for example, is sequentially written on the time axis in the two-dimensional chart recording area 20, and the trend of the biological information is displayed. Is displayed. Then, when the elapsed time after activation exceeds the preset full-scale time of the time axis while such a state is maintained, in step S5, the entry position determined in step S4 is the time axis. It is judged to be out of the full scale of (horizontal axis 78). In this state, step S7 is executed, an alarm output indicating replacement of the anesthesia recording paper 18 is output, the replacement command lamp 80 is turned on, and an alarm sound is output from a sounding device (not shown).
In the following step S8, a full scale on the time axis is automatically set and a new entry position is determined based on the new full scale. This new full-scale value is the time after the time corresponding to the length of the time axis has elapsed from the present. Then, in step S9, the anesthesia recording paper 18
Will be determined. This judgment 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 to enter the standby state, but if the anesthesia recording paper 18 is replaced, the steps S6 and thereafter are executed.

As described above, according to the present embodiment, the position of the two-dimensional diagram recording area 20 in which the symbol indicating the biological information is automatically written by the XY plotter 22 is set so that the carriage 34 is anesthetized along the preset direction. By being moved relative to the recording paper 18, since it is calculated from the position of the print line printed on the grid surrounded by the vertical axis 76 and the horizontal axis 78 at a constant interval detected by the optical sensor 82, Print misalignment and anesthesia record paper 18
Even if the position of the two-dimensional diagram recording area 20 varies due to expansion and contraction of the anesthesia recording sheet 18 or the placement of the anesthesia recording paper 18 on the mounting table 24 is deviated, the two-dimensional diagram recording area 20 is accurately positioned at a predetermined position. Will be filled in.

Moreover, since the anesthesia recording paper 18 is mounted on the XY plotter 22 mounting table 24, other recording items such as the name of the anesthesia agent dispensed and the dispensing time are automatically recorded even when the biometric information is automatically filled. Has the advantage that it can be handwritten in a predetermined place on the anesthesia recording paper 18.

Further, according to the present embodiment, when the entry position of the symbol exceeds the full scale of the time axis in the two-dimensional diagram recording area 20, an alarm is automatically output and the symbol is changed to a new anesthesia recording paper 18. Is performed, there is an advantage that the anesthesia recording paper 18 is accurately filled.

Although one embodiment of the present invention has been described above with reference to the drawings, the present invention can be applied to other aspects.

For example, although the two-dimensional diagram recording area 20 is configured to be detected by the optical sensor 82 in the printed line detection device of the above-described embodiment, the grid of the two-dimensional diagram recording area 20 is printed with magnetic ink, The recording area detecting means may be configured by providing the carriage 34 with a magnetic head for detecting the lines forming the grid.

Further, in the above-described embodiment, when detecting the position and size of the two-dimensional diagram recording area 20, the optical sensor 82 crosses the central portion of the two-dimensional diagram recording area 20 in the X direction and the Y direction.
The optical sensor 82 is scanned twice in the X direction so as to intersect the two-dimensional diagram recording area 20 at a position separated by a certain distance in the Y direction.
Is a two-dimensional diagram recording area 20 at a position separated by a certain distance in the X direction
The scanning may be performed twice in the Y direction so as to intersect with. By doing so, there is an advantage that the inclination and distortion of the two-dimensional chart recording area 20 are also detected, and the symbol can be more accurately entered.

Further, in the above-mentioned embodiment, the blood pressure value, the pulse rate, the automatic blood pressure monitor 10 that can measure the respiratory rate, etc. were used, but instead of or in addition to it, the biological information necessary for biological monitoring such as body temperature is displayed. A measuring device may be provided.
