Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blood pressure display device, and more particularly to a device for displaying a predetermined warning for a measured blood pressure value.

[0002]

2. Description of the Related Art In recent years, awareness of health management has increased in individuals, and in addition to a conventional hyperemic stationary blood pressure monitor that uses an air pump, a wristwatch-type device that detects blood flow at the fingertips to measure blood pressure A sphygmomanometer that is easy to carry is also provided (for example, see Japanese Patent Laid-Open No. 4-200439).

Further, in the above portable blood pressure monitor,
The measured maximum blood pressure and minimum blood pressure values are automatically recorded and displayed in a graph to show their continuous changing trend. When each value exceeds the set value, the corresponding part on the graph blinks to warn. Some display is also known.

[0004]

However, the above-mentioned warning display is merely a display when the measured value exceeds a general standard value, and does not correspond to each physical condition. Not only does it play an important role, but it may even cause an excessive warning display and have a negative psychological effect.

As a result of consideration by the present inventor, in view of such inconvenience, the optimum blood pressure allowable range for each individual exists for both the maximum and minimum blood pressures, and it is determined whether or not there is a measured value within the allowable range. However, it has been found that the above problems can be solved all at once by displaying a predetermined warning for the first time when a value outside the allowable range is measured.

The present invention has been made on the basis of the above-mentioned findings. It is possible to set an allowable range individually for the maximum and minimum blood pressures, and a predetermined warning display is displayed when a blood pressure value outside the allowable range is measured. By doing
It is an object of the present invention to provide a blood pressure display device that can give more accurate information to an operator and reduce unnecessary worries.

The present invention further utilizes that blood pressure is measured by measuring a pulse and a cardiac wave, and a predetermined warning is displayed when the measured pulse deviates from preset upper and lower limit values. An object of the present invention is to provide a blood pressure display device capable of more accurately determining the state of the body together with the blood pressure warning display.

[0008]

In order to achieve the above-mentioned object, a blood pressure display device according to the present invention has a systolic blood pressure A and a diastolic blood pressure A as shown in FIG. Blood pressure measuring unit 1 for individually measuring the value of B
0, a comparison value setting unit 12 capable of manually setting the allowable range C of the measured maximum blood pressure value A and the allowable range D of the measured minimum blood pressure value B, and the blood pressure value measured by the blood pressure measurement unit 10 described above. The data storage unit 14 stores the allowable ranges C and D set by the A and B and the comparison value setting unit 12.

Further, the blood pressure value and the allowable range stored in the above-mentioned data storage unit 14 are individually compared with respect to the systolic blood pressure and the diastolic blood pressure, and when the respective blood pressure values deviate from the allowable range value, a comparison unit 16 is generated. And a display unit 18 for displaying a warning corresponding to the signal output from the comparison unit 16.
It has and.

The blood pressure measuring unit 10 is composed of a pulse detecting unit 48 and an electrocardiographic wave detecting unit 46, and the comparison value setting unit 12 manually sets the upper limit value and the lower limit value of the pulse. It can be set individually, and the above-mentioned data storage unit 14
Is capable of storing the pulse value measured by the pulse detection unit 48 and the upper limit value and the lower limit value of the pulse set by the comparison value setting unit 12, and the pulse value stored in the data storage unit 14 by the comparison unit 16 described above. Is compared with the upper and lower limit values thereof, and a predetermined signal can be generated when the pulse value deviates from the upper and lower limit values thereof, and a predetermined signal corresponding to the signal output from the comparison unit 16 is displayed on the display unit 18 described above. It is preferable to display a warning.

[0011]

Before the blood pressure is measured, the allowable ranges C and D of the systolic blood pressure and the diastolic blood pressure of the subject are individually stored in the data storage unit 14 via the comparison value setting unit 12. When the blood pressure is measured by the blood pressure measuring unit 10 in such a state, the measured maximum blood pressure value A and the measured minimum blood pressure value B are individually stored in the data storage unit 1.
Stored in 4.

Further, the systolic blood pressure value A stored in the data storage unit 14 as described above and the allowable range C thereof are compared by the systolic blood pressure comparing unit 16a, and the systolic blood pressure value A is a value outside the allowable range C. When it is determined, a predetermined signal is sent to the display unit 18 to display a warning. Similarly, the minimum blood pressure value B is compared with the allowable range D in the minimum blood pressure comparison unit 16b, and if a value outside the allowable range D is recognized, the display unit 1
A predetermined warning is displayed at 8.

[0013]

As described above, according to the present invention, it is possible to set the allowable range for the systolic blood pressure and the diastolic blood pressure individually corresponding to the individual measurer, and the warning is displayed only when the measured value is out of the range. Since this is performed, a more accurate display is provided to the person who measures the blood pressure, overlooking of the abnormality can be prevented, and psychological anxiety due to excessive warning can be prevented.

Further, with respect to the pulse measured at the same time as the blood pressure measurement, the upper and lower limit values are set in substantially the same manner as the blood pressure, and a warning is issued when the measured value deviates from the range so that the physical condition can be improved. Combined with the blood pressure display,
It is displayed more clearly.

[0015]

[Embodiments] The following is an example of carrying out the present invention on a portable blood pressure monitor configured in a wristwatch form, but the present invention is not limited to this, and is substantially the same for various types of blood pressure monitors such as a stationary type. Of course you can.

The blood pressure monitor 20 embodying the present invention has a liquid crystal display plate 24 at the center of the front surface of a hollow watch-type main body case 22 having an opening on the back surface side, as shown in FIG.
In addition to the above, a first electrode 26 for detecting an electrocardiographic wave and a blood pulsating flow detector 28 are provided below the display plate 24. Further, while a plurality of push button switches 30 are provided on the side surface of the main body case 22, the control circuit 32 shown in FIG. It is closed by a metal back cover (not shown) provided, and a band 35 is provided at the top and bottom.

As the control circuit 32, a one-chip microcomputer is used, and its operation is controlled by a program stored in the ROM 36 in advance so that at least each function as the blood pressure display device shown in FIG. 1 can be realized. is there. That is, while adjusting the operation timing by the clock signal sent from the clock signal generator 38, the CPU
The control unit 40 having the above-mentioned performs control or arithmetic operation according to the program in the ROM 36, and stores the result in the RAM 42 provided as the data storage unit 14.

The control unit 40 further includes a data input unit 44 and a blood pressure measurement unit 10 on the input side, and a display unit 18 on the output side.

The data input section 44 sends a predetermined signal to the control section 40 when detecting the push operation on the push button switch 30 described above.
The function as the comparison value setting unit 12 described above is realized by changing the operation mode of the control circuit 32 in conjunction with the pushing operation of or by manually storing arbitrary data in the RAM 42.

Furthermore, the first and second for detecting the electrocardiographic wave
The electrocardiographic signal of the human body, which is input through the electrodes 26 and 34, is captured by the electrocardiographic signal detection unit 46, and a signal corresponding to the heartbeat can be detected, while the pulsating flow detector 28 including a light emitting diode and a phototransistor is used. The pulsation of the blood flowing to the fingertip is captured, and the pulse detector 48 can detect the pulse at the fingertip from the pulsation signal. Using the timing of the electrocardiogram and pulse detected in this way, the delay time required for the pulsation to reach the fingertips through the blood vessels after pushing out the blood after the heart beats is measured by the conventional method. Similarly, the systolic blood pressure A and the diastolic blood pressure B of the subject can be individually measured, thereby realizing the function of the blood pressure measurement unit 10 described above.

The display unit 18 includes a sounding device 50 such as a buzzer which sounds and displays a display corresponding to the calculation result in the control unit 40 and a display plate 24 which visually displays by light. Composed of and.

The present invention is characterized by the contents displayed on the display section 18 described above. That is, as illustrated in FIG. 4, in addition to the display similar to the conventional one regarding various measured values such as the systolic blood pressure A, the diastolic blood pressure B, or the pulse rate E, the allowable range or pulse of the systolic blood pressure and the diastolic blood pressure is displayed. Setting values for upper and lower limits C ・ D
And a display F indicating whether or not the measured value is within a predetermined setting range, and the respective display areas are separately arranged on the display plate 24.

On the other hand, the RAM 4 provided in the data storage unit 14
2, the upper limit value C1 and the lower limit value C2 of the systolic blood pressure, the upper limit value D1 and the lower limit value of the diastolic blood pressure corresponding to each display value displayed on the display plate 24 as shown in FIG. A storage area 52 for "D2" and "upper limit value and lower limit value of pulse", and an area 54 for individually storing values of "maximum blood pressure A, minimum blood pressure B and pulse rate E" obtained by measurement or calculation are provided. . Regarding the measured value storage area 54, a storage area 54 of 30 or more groups is provided, and
When the measured values exceeding the set number of sets are input, the oldest ones are sequentially deleted, so that the blood pressure change in the period of the past one month or the like is automatically recorded. It should be noted that it is possible to save only the past highest and lowest values when deleting the past.

Next, the procedure for displaying the blood pressure in the sphygmomanometer 20 will be described in more detail with reference to the flow chart shown in FIG. 6, but it goes without saying that the procedure for displaying the pulse rate is substantially the same.

When the control circuit 32 is reset and started, it is asked in step 71 whether or not a comparison value is set. Immediately after the start, since no special data regarding the blood pressure subject is set in the RAM 42, the process proceeds to steps 72 and 73 to set the allowable ranges C and D for the maximum blood pressure and the minimum blood pressure.

The setting operation is input by using the push button switch 30 of the data input section 44.
After the push button switch 30 is pressed to enter the data input mode, the setting operation is performed by changing the numerical value according to the number of times the push button switch 30 is pressed according to the instruction displayed on the display plate 24.

For example, in the illustrated example, a standard graph prepared in advance corresponding to the age and the physical condition of the individual,
Or, according to the doctor's instructions, set the maximum blood pressure tolerance range to "1.
If the allowable range of the minimum blood pressure is set to "120 to 50" in step 73 in step 72 for "80 to 90", the value is stored in the setting area 52 from a predetermined address on the RAM 42 and displayed on the display board 24. In the upper left and right in the left, set values C1 and C2 for systolic blood pressure on the left
However, the set values D1 and D2 for the diastolic blood pressure are individually displayed as concrete numbers on the right side.

When the comparison value setting is completed as described above, the routine proceeds to step 74, where it is judged whether or not the blood pressure should be measured. When the start of blood pressure measurement is selected by mode switching in the data input unit 44, the blood pressure measurement unit 10 separately captures the cardiac wave and the pulsation wave, and the systolic blood pressure (137 in the illustrated example) is obtained in step 75 from the values of both parties. ,
In step 76, the minimum blood pressure (65 in the illustrated example) is calculated, and the values A and B and the pulse rate E are individually stored in the storage area 54 on the RAM 42.

Further, when it is determined in step 77 that the blood pressure measurement has failed, a predetermined error is displayed on the display plate 24 in step 78, and then the process returns to step 74 to prompt another blood pressure measurement. On the other hand, when it is determined in step 77 that the measurement is successful, the systolic blood pressure A and the diastolic blood pressure B are numerically displayed in the measurement value display area on the display plate 24 in step 79, and then the process proceeds to step 80 and the measurement is performed. Enter the value judgment process.

In this determination process, it is determined in step 80 whether the measured maximum blood pressure A is within the allowable range C, and if it is determined that the maximum blood pressure A is within the allowable range C, then step 81 is performed.
Then, it is determined whether the lowest blood pressure B is also within the allowable range D. If it is determined that both values are within the allowable range, in step 82, for example, "O" is displayed in the warning display area.
The display F with the letter "K" is performed to show that the blood pressure value is acceptable for the subject.

On the other hand, when it is determined that at least one of the maximum blood pressure and the minimum blood pressure is out of the above-mentioned allowable range, the warning display F to that effect is displayed in characters in step 83, and at the same time, the sound generator 50 is activated. After making a sound, the operator is notified of the abnormality in the measured value, and then the process returns to step 74, and a determination is made as to whether or not the blood pressure measurement should be further repeated.

The contents displayed on the display board 24 and the arrangement thereof can be changed as appropriate.
Various functions such as clock function and temperature measurement function can be provided at the same time. Furthermore, it goes without saying that the contents judged at the time of blood pressure measurement can also display various calculation results based on the measured data, including the difference between the systolic blood pressure and the diastolic blood pressure. The display content can be concretely shown by using a voice synthesizing means instead of the buzzer sound.

Also, in the method of setting the allowable range of blood pressure and the upper and lower limit values of pulse, instead of directly inputting specific numerical values as described above, a table in which numerical values are set in advance for each pattern is stored in the ROM. The data may be prepared and necessary data may be selected from the data. Further, the configurations of the data input unit 44 and the blood pressure measurement unit 10 are not limited to those in the above-mentioned embodiments, and it goes without saying that they can be appropriately modified and implemented.
