Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a blood pressure monitor that measures and records blood pressure values every time a certain period of time elapses, a so-called ambulatory blood pressure monitor (blood pressure monitoring device). Regarding.

<Prior art> In general, an ambulatory blood pressure monitor measures blood pressure values every hour, for example, and records them on a floppy disk, etc., every time a certain period of time elapses. This makes it possible to understand changes in direct pressure values.

<Problems to be Solved by the Invention> However, in the conventional ambulatory blood pressure monitor, the blood pressure value is measured every time a certain period of time elapses.
Therefore, when the subject moves his or her arm during measurement, it may be affected by noise.
There was a drawback that the measured blood pressure value may differ from the original blood pressure value.

The present invention has been made in view of the above points, and provides a blood pressure monitor that can more accurately grasp changes in blood pressure values by reducing the influence of erroneous measurement values as much as possible. The purpose is to

<Means for Solving the Problems> In order to achieve the above-mentioned object, the present invention measures blood pressure values multiple times every time a certain period of time elapses, and processes the multiple measured values as data. The blood pressure monitor records measurement data obtained by measuring the blood pressure, the blood pressure monitor comprising: a measuring means for measuring a blood pressure value; and a measuring means configured to measure the blood pressure value a plurality of times each time the predetermined period of time elapses. a control means for controlling the plurality of measured values from the measuring means, a data processing means for processing the plurality of measured values from the measuring means in a preset method and outputting the measured data as the measured data, and recording the measured data from the data processing means. It is equipped with a recording means for recording.

According to the above configuration, blood pressure values are measured multiple times every time a certain period of time elapses, and the multiple measured values are data processed, for example, averaged, using a preset method. Since the measurement data is recorded as measurement data, the reliability of the measurement is improved compared to the conventional method, which takes - measurements every time a certain period of time elapses and records the measured values as they are. become.

<Examples> Examples of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a schematic diagram of an ambulatory blood pressure monitor according to an embodiment of the present invention. In the figure, ■ is a measuring means for measuring a blood pressure value, and this measuring means 1 is equipped with a cuff 2 and a sensor 3 that converts the pressure from the cuff 2 into an electrical signal. 4 is a display means for displaying measured data, etc.;
5 is a recording means such as a printer for recording measurement data, which will be described later; 6 is a human power means having operation keys for setting power on/off and measurement time intervals; and 7 is a data storage means which controls each part and which will be described later. A microcomputer that performs processing.

In the ambulatory blood pressure monitor of this embodiment, when it is affected by noise etc., in order to reduce the influence as much as possible so that changes in blood pressure values can be grasped more accurately, Each time the blood pressure value elapses, the blood pressure value is continuously measured a plurality of times, and the measurement data obtained by data processing the plurality of measured values is recorded.

For this reason, the microcomputer 7 includes a control means that controls the measuring means I so that the blood pressure value is measured several times in succession every time a certain period of time passes, and a control means that controls the measuring means I so that the blood pressure value is measured several times in succession. It has a function as a data processing means for data processing measured values in a preset method and outputting them as measured data to the recording means 5.

A certain fixed time and a plurality of times are set in advance by the input means 6. In this embodiment, one hour is set as a certain fixed time, and three times are set as a plurality of times.

Furthermore, in this embodiment, as data processing according to a preset method, a plurality of measured values are averaged to obtain measured data.

FIG. 2 is a flowchart for explaining the measurement operation of the ambulatory blood pressure monitor having the above configuration.

First, in step n1, it is determined whether the power switch is turned on and the measurement mode is entered. When it is determined that the measurement mode is entered, the process moves to step port 2, and after a certain period of time has elapsed, the measurement time is reached. When it is determined that the measurement time has come, the process moves to step n3. In step n3, the blood pressure value is measured a plurality of times, three times in a row in this embodiment, and the process moves to step n4.

In step n4, the three measured values are data processed using a preset method. In this embodiment, the three measured values are averaged as measured data, and the process moves to step n5. In step n5, the obtained measurement data is recorded by the printer of the recording means 5, and the process moves to step n6. In step n6, it is determined whether the measurement mode has ended, that is, whether the blood pressure monitoring time has elapsed, and when it is determined that the measurement mode has ended, it is determined that the measurement mode has not ended. When this happens, the process returns to step n2.

In this way, each time a certain period of time elapses, measurements are taken three times in a row and the average value is recorded as measurement data, so each time a certain period of time elapses,
Compared to the conventional example in which measurements are taken twice and the measured values are recorded as they are, the influence of erroneous measurements due to noise, for example, is reduced and the reliability of measurements is improved.

In the above-mentioned embodiment, data processing is performed by taking an average, but in another embodiment of the present invention, among the measured values obtained by multiple measurements, very distant measured values are ignored and other values are calculated. Alternatively, the average of the measured values may be taken.

<Effects of the Invention> As described above, according to the present invention, the blood pressure value is measured multiple times each time a certain period of time elapses, and the multiple measured values obtained are measured using a preset method. Since the data is processed as measured data and recorded, this method is faster than the conventional method, in which measurements are taken - times every time a certain period of time elapses, and the measured values are recorded as they are. This reduces the influence of erroneous measurement values due to noise, etc., and improves the reliability of measurements.
