Abstract

PROBLEM TO BE SOLVED: To provide a method of displaying measurements for an automatic sphygmomanometer which is capable of solving such a problem that measurements must be carried out several times and the stable values must be averaged to judge the severeness of hypertension because blood pressure fluctuates due to various causes despite the convenience of an electronic sphygmomanometer. SOLUTION: Pressurizing/depressurizing a cuff (pressurizing belt) is repeated two or more cycles, preferably three cycles, each average value and measured value of the highest blood pressure (systolic blood pressure), the lowest blood pressure (diastolic blood pressure) which are measured for every cycle and pulse rate per minute, and the vertical maximum deviation between the measured value and the average value are automatically calculated and displayed. Furthermore, the number of cycles to be repeated can be preset.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for measuring and displaying an electronic automatic sphygmomanometer.

[0002]

2. Description of the Related Art An electronic automatic sphygmomanometer widely used at home uses a pressure sensor in a cuff (compression zone) to measure the change in the vibration pattern of the artery wall. Similarly, the point where blood flow is resumed is systolic blood pressure (systolic blood pressure), and the point where the amplitude decreases and the amplitude decreases to a certain amplitude is diastolic blood pressure (diastolic pressure). Blood pressure). Such an automatic sphygmomanometer can measure not only the upper arm but also the wrist as long as it can touch the arterial pulsation, and since it has reproducibility and the error due to the measurement site is relatively small, the blood pressure of the patient is managed on a daily basis. This is a very convenient measuring instrument, and has recently begun to be used not only at home but also in medical institutions.

[0003] On the other hand, as is well known, the blood pressure varies greatly for various reasons, and therefore, even when continuously measured, the systolic blood pressure (systolic blood pressure) is 20 to 30 mmHg, and the diastolic blood pressure (diastolic blood pressure) is 10 to 15 mmHg. It is not unusual for the degree to vary. Therefore, in the case of a person who is usually close to the upper limit of normal blood pressure, blood pressure in either systole or diastole often shows mild to moderate hypertension with only one measurement, which is more than necessary. You have to worry about administering antihypertensive drugs. For this reason, in blood pressure determination, it is desired to measure two or more times (2 to 3 times) after deep breathing and to take an average of stable values. For example, the "United States Hypertension Joint Committee" It is recommended that the patient be examined two or more times, that the blood pressure be measured at least twice at each consultation, and that the severity of hypertension be determined based on the average of all the measured values.

[0004] Therefore, in order to obtain a proper measurement value using an automatic blood pressure monitor, in the conventional method, the measurement values obtained by performing measurement a plurality of times are recorded, and the average value is obtained after observing the dispersion of the measurement values. Complicated work such as calculation was required. Further, in order to check for arrhythmia at the same time as blood pressure measurement, it is necessary to observe the variation in measured values of the pulse several times. On the other hand, since variations in blood pressure and pulse are influenced by individual differences and state differences, it is needless to say that it may be better to increase or decrease the number of repetitions according to the situation.

[0005]

SUMMARY OF THE INVENTION In view of the above, the present invention eliminates the above-mentioned cumbersome labor when measuring blood pressure, and provides an automatic blood pressure monitor capable of automatically and easily obtaining appropriate measurement values with high reproducibility. It provides a measurement display method.

[0006]

According to the first aspect of the present invention, a cuff (pressurizing band) is provided in order to save troublesome operations such as recording a plurality of measured values and calculating an average value. )
Is automatically repeated for 2 or more cycles, preferably 3 cycles, and the mean values of systolic blood pressure (systolic blood pressure), diastolic blood pressure (diastolic blood pressure) and pulse rate / minute measured at each cycle are finally calculated. This is a measurement and display method for an automatic sphygmomanometer, which is automatically calculated and displayed at the end of a cycle.

According to a second aspect of the present invention, the dispersion of the measured values can be easily determined. In the first aspect of the present invention, the upper and lower maximum deviation between the measured value and the average value is automatically determined. This is a measurement display method for an automatic sphygmomanometer, characterized in that the calculated and displayed average value is indicated by adding +-to each of the average values.

According to the third aspect of the present invention, the number of repetitions can be increased or decreased according to the situation such as individual difference or state difference. A measurement and display method for an automatic sphygmomanometer characterized in that it can be set in advance by a method of designating the number of times a provided push button is pressed.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an explanatory view showing a plan view of an embodiment of the automatic sphygmomanometer of the present invention.

As shown in the embodiment of FIG. 1, a normal automatic blood pressure monitor such as a display panel 2, a power button 3 and a pressure button 4 for a cuff (pressure band) is provided on the surface of the main body 1 of the automatic blood pressure monitor. In addition to the above, a repetition number button 5 is provided so that the number of pressurization / decompression cycles of the cuff can be set by the number of times the repetition number button 5 is pressed. Inside the main body 1 (not shown), in addition to the usual electronic automatic sphygmomanometer equipment such as a power supply, an air compressor communicating with a cuff containing a pressure sensor through a rubber tube, and a piezoelectric conversion electronic element, An arithmetic unit for automatically calculating the average value of the blood pressure and the pulse rate and the maximum vertical deviation value is housed therein.

The operation sequence in the above configuration will be described below. First, when the power button 3 is pressed after winding the cuff around the upper arm (or wrist), the display on the display panel 2 disappears and the preparation for measurement is completed. Next, when the press button 4 is pressed after pressing the repetition number button 5 for the number of measurement cycles to be specified,
The pressurization and depressurization of the cuff are repeated, and the following measurement is automatically performed during one cycle, similarly to a normal automatic blood pressure monitor. That is, the artery is compressed by the pressure of the cuff set in advance, and the blood flow is once stopped, and then gradually decompressed. During this time, the point at which the blood flow resumes, ie, the systolic blood pressure (systolic blood pressure),
The point at which the pressure is further reduced to a constant amplitude, that is, the diastolic blood pressure (diastolic blood pressure), and the pulse rate / minute therebetween are measured. When such a measurement is repeated and the designated cycle is completed, the average value and the maximum vertical deviation of each measured value of each cycle are automatically calculated by the arithmetic unit and displayed on the display panel 2.

Next, an operation example of the measurement display and its significance will be described below with reference to FIG. The cuff is wrapped around the upper arm, the power button 3 is pressed, then the repetition button 5 is pressed three times, and then the pressurization button 4 is pressed. The systolic blood pressure (systolic blood pressure) and the diastolic blood pressure (diastolic blood pressure) obtained in each cycle are obtained. The blood pressure) and the pulse rate / minute were the values shown in Table 1, respectively.

[0013]

[Table 1]

The average value and the maximum vertical deviation of the blood pressure and the pulse rate are as shown in Table 2 below.
It is automatically calculated at the end of the last cycle and is displayed as shown in FIG. In the figure, 6 is the average value of systolic blood pressure, 7 is the average value of diastolic blood pressure, 8 is the average value of pulse rate / minute, 9, 10
Denotes upper and lower maximum deviation values of systolic blood pressure, 11 and 12 denote upper and lower maximum deviation values of diastolic blood pressure, and 13 and 14 denote upper and lower maximum deviation values of pulse rate / minute, respectively.

[0015]

[Table 2]

The average value of the blood pressure in Table 2 satisfies, for example, the normal range of systolic blood pressure <130 and diastolic blood pressure <85 in the blood pressure classification of the United States Hypertension Joint Committee Fifth Recommendation (1992). If the judgment is made only by the second measurement value of 1, both the maximum and minimum blood pressures will exceed this limit value. There is a risk of leaving. According to the present method, the average value and the variation of the blood pressure can be automatically checked by one measurement, so that such a problem can be solved. In this example, the number of repetition cycles is set before measurement.
Needless to say, the number of cycles may be fixed to, for example, three, and the repeated button 5 may be omitted.

[0017]

As is well known, blood pressure greatly fluctuates due to various causes, and it is not unusual for a difference of about 20 to 30 mmHg to occur even when continuous measurement is performed. The shot measurement may show a blood pressure value that requires administration of an antihypertensive agent. In the conventional method, complicated measures such as recording multiple measurements and calculating the average value and checking the dispersion of the measured values were required. Just by adding the calculation function of addition, subtraction, multiplication, and division, the blood pressure average value and its variation are displayed multiple times, so that a reasonable blood pressure with high reproducibility can be easily obtained.
Since the variation of the pulse rate / minute is known, there is an effect that the presence or absence of arrhythmia can be checked.

As apparent from the above description, according to the present invention, it is possible to provide a convenient automatic blood pressure monitor measurement and display method that can be used not only at home but also in medical institutions for daily health management. it can.
