Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention displays collected signal waveforms as continuous waveforms over time on a recording medium, and displays collected signal values at predetermined timings separately from the continuous waveform display area. The present invention relates to a status display device for displaying information in an area and an alarm display method in the status display device.

[Conventional technology] Automatically measures biological information from a subject such as an electrocardiogram waveform, and converts the measured electrocardiogram waveform and other biological information to C in real time.
Among biological information processing devices that display on RT display devices and record measurement results on recorders, we also employ devices that are placed on the bedside, collect patient information, and transmit it to nurse centers, etc. It has been done.

Some of these systems automatically monitor whether the information collected from the subject falls within a preset range, and if the information is outside the range, an alarm sounds, etc. There is something that is output and calls attention to it.

[Problem to be solved by the invention] However, even in such cases, most of the systems simply notify the occurrence of an alarm, and in order to investigate the state at the time of the alarm occurrence, it is necessary to newly measure the occurrence of the alarm In most cases, values can only be confirmed by reading out the alarm value and displaying the read alarm value, making the operation unavoidable.

In addition, on CRT display devices, etc., it is possible to call attention by displaying the alarm occurrence state and the measured value at the time of occurrence intermittently or by displaying it in reverse video, but in the case of recorders, etc. It is not possible to use such a method.

That is, a threshold setting means for setting an alarm display threshold for the collected information, a determining means for determining whether the collected information is within the threshold range set by the setting means, and a determining means for determining whether the collected information is within the threshold range. The collected value display means displays the value in a normal thickness, and displays the collected information value in a thicker thickness than the normal thickness when the judgment means determines that the value is outside the threshold range.

[Function] With the above configuration, when an alarm occurs, it is possible to understand the cause of the alarm (alarm generation source, etc.), and the specific alarm status value at the time of the alarm occurrence can be easily distinguished from others. You can quickly check the alarm value without any special operations.

In FIG. 2, 250 is seven fixed switches,
In contrast to the touch keys arranged on the display surface of the display unit 200, which are assigned functions depending on the displayed content, fixed functions are assigned regardless of the displayed content.

The alarm notification threshold setting process and the display control process when an alarm occurs will be described below with reference to the flowcharts of FIGS. 3 and 4 in this embodiment having the above configuration.

First, the alarm threshold setting process of this embodiment will be explained with reference to FIG.

The CPU 1 is the operation panel 250 of the device 510 of this embodiment.
When the alarm key 250a is pressed and the alarm threshold setting process is selected, the process shifts to the process shown in FIG. First, in step S1, an alarm setting screen shown in FIG. 5 is displayed on the display section 200. Then, in step S2, it is monitored whether any display key portion of the operation panel 250 is selectively pressed.

When any display part of the operation panel 250 is pressed, the process advances to step S3, and it is checked whether the pressed input is the alarm-on key display part shown at 501 in FIG. If the alarm-on key display portion 501 is touched, the process advances to step S4, where an alarm-on mode is set in which alarm occurrence is monitored and an alarm sound is output when an alarm occurs, and the process returns.

On the other hand, if the alarm on key display area 501 is not touched, the process proceeds from step S3 to step S5, and it is checked whether or not the pressed input is on the alarm off key display area shown at 502 in FIG. Alarm off key display part 50
If 2 is touched, the process advances to step S6, where an alarm off mode is set in which normal control is maintained in which no alarm 1 sound is output when an alarm occurs, and the process returns.

Further, if the alarm off key display area 502 is not touched, the process advances from step S5 to step S10, and it is checked whether the pressed input is the alarm interrupt key display area shown at 503 in FIG. Alarm interrupt key display part 5
If 03 is touched, the process proceeds to step Sll, and a mode is set in which all alarm monitoring processing, alarm warning output processing, etc., including monitoring whether the measured value is within a preset threshold value, are suspended for a certain period of time. This certain period of time is, for example, 3 minutes. The input of this key is used, for example, when there is a first alarm and when the alarm is to be prevented from being output for a certain period of time after this alarm is recognized.

2 If the alarm interrupt key display portion 503 is not touched in step S10, the process proceeds from step S10 to step S15.
The program then proceeds to check whether the pressed input is in the alarm darkness value setting key display area shown at 504 in FIG. If the touch input is not on the alarm threshold setting key display area 504, the touch input is on an invalid area, so the process returns to step S2 and waits for a touch input on the correct display area.

In the case of a touch input on the alarm threshold setting key display section 504, the process advances from step 315 to step S16, where the display interface 21 is controlled and the display section 200 is displayed.
The threshold setting screen shown in FIG. 6 is displayed.

On the threshold setting display screen, a slide volume for alarm setting is displayed for each collected signal, and by pressing the upper and lower limit setting keys with arrows, you can set the upper and lower thresholds and change the alarm on/off value. .

The screen shown in Figure 6 is an example of a display when alarms can be set for electrocardiogram, three blood pressure lines, body temperature, and breathing.
1 is the heart rate alarm upper and lower limit setting, and 622 is the blood pressure value 1 alarm upper and lower limit setting (S.

D, M), 623 is blood pressure value 2 alarm upper and lower limit setting (S,
D, M), 624 is blood pressure value 3 alarm upper and lower limit setting (S,
D, M), 625 is the temperature alarm upper and lower limit setting (Tl, T
2. △T), 626 is the respiratory alarm upper and lower limit setting (RR,
This shows a case where it is possible to set each threshold value of (APN).

However, the alarm threshold value is not limited to each collected signal value as described above, and an alarm threshold value can be set for arbitrary measurement data, and alarm monitoring can be performed.

Alarm (ON), (OFF) key 610 on the left side of the screen
(ON)/(OFF) key display parts 611 to 616
By pressing and inputting, it is possible to specify whether the alarm should be turned on or off for each parameter.

Furthermore, the upper and lower limits of the alarm can be set for each parameter using the slide volume at the center of the screen. Pressing the (+-) (→) keys on the left side increases or decreases the lower limit value, and pressing the (1-) (→) keys on the right side increases or decreases the upper limit value. These upper and lower limits can be confirmed by sliding the slide volume display.

For heart rate, if you press the (auto) key, the upper and lower limits are automatically set based on the current heart rate.

For blood pressure, by displaying (S), (D), (M), etc. in the center and pressing a key, the setting items will change from Sys to 5Dia-IMean, and you can set alarms for each. can.

Similarly, for body temperature, by pressing a key displayed as (T1), etc., the setting items change from T1 to T2 to ΔT, and an alarm can be set for each.

Regarding breathing, by pressing the key displayed as (RR) etc., the setting items will change to RR-APN.
Alarms can be set for breathing rate and apnea time. In addition, the current measured values of each parameter are displayed below each volume, and each alarm threshold value can be determined with reference to this current measured value.

Therefore, in steps S17 to S21, it is monitored whether any of the keys shown in FIG. 6 is pressed manually.

6 Alarm (ON), (OFF) key 610 on the left side of the screen
(ON)/(OFF) key display parts 611 to 616
If the key is pressed, the process advances from step S17 to step S25, and the alarm on/off control for the input parameter is performed. When ON, alarm monitoring processing is performed according to the parameter, and when OFF is input, alarm monitoring according to the parameter is not performed. Then, the process returns to step S17.

This (ON)/(C)FF) key display part 611-6
The key portion where 16 is lit (the shaded portion in FIG. 6) is the currently selected mode.

On the other hand, on the left side of the slide volume display area in the center of the screen (
-) If the (→) key is input, the process proceeds from step S18 to step S27, where the lower limit value of the alarm generation threshold is increased or decreased. This lower limit value can be confirmed by sliding the slide volume display. Then, the process returns to step S17.

On the other hand, on the right side of the slide volume display in the center of the screen (
If the ←) (→) key is input, the process proceeds from step S19 to step S29, where the upper limit value of the alarm generation threshold is increased or decreased. This upper limit value can be confirmed by sliding the slide volume display. Then, the process returns to step S17.

In addition, if the key at the bottom center of the slide volume display section in the center of the screen is pressed manually, the process advances from step S20 to step S31, and the setting items of the corresponding parameters can be changed in sequence, and the setting items selected by this operation can be changed as described above. By repeating the threshold setting, a desired alarm threshold can be set.

Note that, as described above, the alarm threshold and the like are automatically set for the heart rate 621.

Furthermore, if the input is a return key input shown at 630 in FIG. 6, the process is ended and the process returns to the basic process.

In the case of manual power on other parts other than these keys, or when there is no input, the human power on the keys is monitored in steps 817 to S21.

In addition, on the basic screen, the threshold value is displayed in the parameter section where the alarm is on, and the rAL is displayed in the parameter section where the alarm is off.
M 0FFJ is displayed.

The process of printing out biometric information to the thermal printer 511 when the threshold values are set as described above will be described below with reference to the flowchart of FIG. 4.

In this embodiment, when collecting biological information, first the guidance cords 513 to 515 connected to the input box 512 are
The electrode section, etc. of the test subject is attached to the measurement site, and the sound collection microphone is also attached to the sound collection position. Techniques for attaching electrodes to subjects,
Since the method of mounting the sound collecting microphone is well known, detailed explanation will be omitted.

Then, select the measurement subject information input as necessary, and follow the display on the display unit 200 to select "
The patient's age, gender, patient identification number, height, weight j, etc. are set and input.The CPU detects this patient information input via the operation panel interface 22. Then, the human power value is saved in RAMB.
Height (0) and weight (weight) were determined manually to the extent possible. Inputting these items will further improve the reliability of the analysis results of the analysis process.

In this embodiment, an information card 160 for patient data filing can be attached, and by inserting the information card 160 for patient data filing into the information card league/recorder 150, data can be written to the information card. The read patient information is read and the read patient information is read as RA.
It will be written to a predetermined area in Ma.

Since collection preparations have been completed through the above processing, the process moves to the processing shown in FIG. 4, and the CPU
13 to 515, the subject information is collected via the input box 512. Then, the subject information collected in step S52 is sequentially stored in the display buffer area in the RAMB, and the stored data is displayed on the display unit 200. This results in
The display unit 200 sequentially displays measurement signal waveforms from the subject.

Subsequently, in step S53, a comparison is made to see if the detected signal value is within the alarm threshold range set in the process of FIG. If the result of this comparison is within the alarm threshold range in step S54, the process proceeds to step S55, where it is checked whether a predetermined time has elapsed. If the predetermined time has not elapsed, the process returns to step S51 to continue displaying the next detection signal and monitoring whether the signal is within the alarm threshold range.

If a predetermined period of time has elapsed in step S55, that is, if new measurement signals for the display screen of the display section 200 have arrived, the process proceeds to step S60 to print out the previous detection signals from the thermal printer 511.

On the other hand, if the detected signal value is outside the alarm threshold range in step S54, the process advances from step S54 to step S57, and it is checked whether the parameter part outside the alarm threshold range is an alarm-on mode part. If the parameter is not the alarm-on mode but the alarm-off mode, the process returns to step S51 and no special processing is performed in response to the occurrence of the alarm.

Step S for alarm on mode parameters
Proceed to 60. At this time, if necessary, the speaker 12
It is desirable to drive 0 and output an alarm sound. This allows you to immediately know when an alarm has occurred.
Parameter values can be confirmed when an alarm occurs, which will be described later, and prompt and appropriate processing can be performed. In this case, the parameter values outside the alarm threshold range are displayed in reverse video on the display section 200 to call the operator's attention. This display may be a warning by intermittent display, or may be the same as a printout by a thermal printer 511, which will be described later.

In step S60, the display data in the signal waveform display area in the display buffer in RAMB is first transferred to the waveform display area in the print buffer. Subsequently, in step S61, it is determined whether or not there is measured data, parameter values, etc. outside the alarm threshold range among the displayed waveforms and collected data in this range.

If there is data outside the threshold range, the process advances to step S62, and the alarm threshold value is determined from among the measured data and parameter values when a predetermined period of time has elapsed since the start of the process or the previous print process, or when the data falls outside the alarm threshold value. Pattern group 4 is opened in the parameter display area of the print buffer so that the values within the range are displayed in the normal thickness, and each measurement data and parameter value outside the alarm range is displayed thicker so that they can be easily distinguished from the normal display. Develops the pattern in the parameter display area of the print buffer. Then, the process advances to step S65.

If there is no measured data or parameter values outside the alarm threshold range in step S61, the process advances from step S61 to step S64, and a pattern is created in the parameter display area of the print buffer so that each measured data and parameter value is displayed in the normal thickness. It is expanded and the process proceeds to step S65.

Then, in step S65, the print data in the print buffer generated in this way is transferred to the thermal printer 5.
11 and returns to step S51.

The 7th example of the printout printed out as above is shown below.
As shown in the figure.

In FIG. 7, the upper part is the measured signal waveform displayed on the display unit 200, and the uppermost row 701 is the measured electrocardiographic waveform (
ECGI), 702 is the measured blood pressure value 1 (BPI), 70
3 is measured blood pressure value 2 (BF2), 704 is measured blood pressure value 3
(BF3), 705 is the respiratory waveform value (RR).

Below these waveform display sections, there is a display area 710 for displaying measurement parameter values and the like specific to this embodiment.

In the display area 710, 711 is an area for displaying measurement times such as parameter values, and it is possible to know alarm generation times and the like here. 712 is the patient bed number,
Reference numeral 713 indicates an area indicating the occurrence of an alarm, and 714 to 723 indicate numerical value display areas for each parameter.

In this embodiment, since "alarm" is displayed in the area 713, it can be immediately recognized that the printout is for the occurrence of this alarm.

714 is the heart rate, 716 is the pulse series, 717 is the body temperature, and 719 to 721 are the blood pressure values 1 to 3. In the display of blood pressure values, (aa) in aa/bb:cc indicates the systolic blood pressure value, (bb) the diastolic blood pressure value, and (CC) the average blood pressure value.

In the print example of FIG. 7, among the above parameter values, the systolic blood pressure value of blood pressure value 1 displayed with a thick line 719 indicates that it is outside the range of the set alarm threshold value. Then, control may be performed so that the parameter shown in the lower row indicates at which point in the waveform display in the upper row, for example, a mark 750 is displayed.

This makes it possible to recognize the specific transition of the detected waveform when it falls outside the alarm range.

In addition, in this embodiment, all parameters of biological information collected from the subject are monitored to see if they are within the alarm threshold range, and the number of parameters that are outside the alarm threshold range is not limited to only one. . Out-of-range may occur in many parameters at the same time, and when an out-of-range alarm occurs in a parameter in alarm-off mode, a printout as shown in Figure 8 is not immediately made, and the parameter in alarm-on mode The parameter value out of the alarm range is displayed only when the parameter value is out of the alarm range or when a predetermined time period has elapsed. FIG. 8 shows an example of a printout when a plurality of parameters are out of the alarm threshold range at the same time.

In the display example shown in Figure 8, rALAR is also displayed in the alarm area.
An MJ display is displayed, and by checking this display, it can be immediately recognized that the printout is for the generation of this alarm.

In Figure 8, outside the alarm threshold range occurs for the respiratory rate RR1 body temperature, the average blood pressure value of blood pressure 1 (BPI), the systolic blood pressure value of blood pressure value 2 (BF2), and the systolic blood pressure value of blood pressure value 4 (BF2). ing.

As described above, according to the printout example of this embodiment, the user can easily check the "alarm" display 713 and the rALARMJ display 800 displayed on the printed recording paper, and can immediately know that an alarm has occurred.

Further, the value of each parameter at the time of an alarm occurrence is optimal for printing out from a printer without any special operation, and is easy to see, and it is possible to easily call attention to the parameter value and confirm the parameter value. Furthermore, at this time, each measured waveform is also displayed, allowing quick and appropriate response.

As a result, the cause of the alarm can be ascertained without any special operation.

In addition, this display output is transmitted to the thermal printer 511 described above.
The present invention is not limited to outputting a printout to a computer, but may also be applied to displaying on a CRT display 200. Of course, the present invention can be applied to any display device, printer, etc. that can output characters in different thicknesses.

[Effects of the Invention] As explained above, according to the present invention, the specific alarm status value at the time of alarm occurrence is displayed and output in a manner that is easily distinguishable from others, so that the alarm status value can be displayed without any special operation. , it is possible to quickly confirm the cause of the alarm occurrence and the specific numerical value of the alarm occurrence.
