More particularly, the present invention relates to a blood pressure measurement device capable of setting a plurality of measurement patterns.

[Background of the Prior Art and the Invention]

The blood pressure value is the most basic among the vital signs of the circulatory system, and is an indispensable index particularly in the diagnosis of hypertension and circulatory diseases. However, in contrast to the peak and diastolic blood pressure, which is said to be 100,000 nights a day on average, most of the conventional blood pressure measurements are performed at any time, measuring only a few points.
For this reason, physical changes caused by exercise, etc., mental changes due to anxiety, tension, etc., cause fluctuations in blood pressure, and as a result, values higher than the original blood pressure value of the subject are measured,
There is a problem that it is difficult to measure the original blood pressure of the subject. Recently, in the treatment of hypertensive patients, it has been desired to administer drugs according to various blood pressure fluctuation patterns of each patient.

In view of the above-mentioned needs, a device (commonly referred to as a 24-hour sphygmomanometer) for automatically measuring blood pressure periodically for a certain period of time, for example, 24 hours is provided to the subject. Have been. This device comprises a measuring device (recorder) carried by the subject for 24 hours, and an analyzing device for outputting measurement data after the measurement is completed and for inputting a new measurement mode to the measuring device. According to this device, it is possible to measure blood pressure appropriately and to know the change in blood pressure for 24 hours, which is very useful for treatment of high blood pressure and the like, but the portable blood pressure monitor itself is considerably large. Because it is large, it places a heavy burden on the person to be measured and also has some restrictions on behavior. The analyzer that processes the data of the portable sphygmomanometer is a desktop-type large-sized dedicated device, and this processor itself is not portable, and is expensive, and costs several million yen including the portable sphygmomanometer. To the extent that it has prevented widespread use of the device. Further, the conventional device is limited to the use as a 24-hour automatic measurement type sphygmomanometer, and cannot be used as a normal type sphygmomanometer for occasional measurement, and cannot print out data at the time of measurement. Was.

In view of the above problems, the applicants have separately proposed a device for solving the above problems.

Next, the processor 2 divides into an opening connected to the sphygmomanometer main unit 1, an input unit for performing various settings, and a process unit (printout unit) for processing and outputting data output from the sphygmomanometer main unit. be able to.

First, the opening 15 is formed so as to correspond to the shape of the tapered portion 1a when the tapered portion 1a of the sphygmomanometer main body 1 is inserted. Terminals connected to terminals formed on the sphygmomanometer main body side are provided on the innermost wall surface of the opening 15, that is, the wall surface facing the end wall surface of the tapered portion when the sphygmomanometer main body 1 is inserted. Is located. Reference numeral 21 denotes a switch board, and reference numeral 22 denotes a display unit for displaying blood pressure, pulse, and the like. Reference numeral 23 denotes a detachable cover provided in the print paper storage unit.

In the illustrated configuration, the sphygmomanometer main body 1 is connected and integrated by inserting a part of the sphygmomanometer main body 1 into the opening 15. However, the present invention is not limited to this configuration. If the connection is made and the connection state is strong enough to withstand use as an integrated sphygmomanometer in the occasional measurement mode described later, it does not matter what the connection method is.

FIG. 2 shows an example of an arrangement state of switches in a switch board unit of the processor.

Among the switches on the switch board 21, S1 is a measurement interval setting switch, S2 is a condition setting switch, S3 is a print switch, S4 is a blood pressure measurement switch, S5 is a selection switch, S6 is a set switch, S7 is an erase / off switch, and S8. Is registered
The start / stop switch and S9 are paper feed switches. The display unit 22 is, for example, a display (LCD) method using liquid crystal.

In the illustrated configuration, the connection between the sphygmomanometer main body 1 and the processor 2 is strengthened by using a special connecting member (separately applied), and the attachment of the sphygmomanometer main body to the subject can be performed. The locking of the integrated device when the sphygmomanometer main body and the processor are integrated can be facilitated.

Next, the use state and the operation state of the present apparatus will be described first in the case of the automatic measurement mode, and then in the case of the optional measurement mode.

In FIG. 3, (charging) First, the operation of the sphygmomanometer main body 1 and the power supply for operating the processor connected to the main body 1 are all provided by the storage battery mounted on the sphygmomanometer main body 1. The plug is inserted into the charging terminal of the sphygmomanometer main body 1 to perform charging. For example, about 300 blood pressure measurements can be performed with one charge.

(Connection with Processor) The tapered portion 1a of the sphygmomanometer main body 1 is connected to the opening 15 of the processor 2.
And the sphygmomanometer main body 1 and the processor 2 are connected.
At this time, if the terminals of both devices are securely connected, it is desirable to inform that the two devices are properly connected by lighting a lamp or emitting a specific sound. The processor 2 is operated by the power supply of the sphygmomanometer main body 1 by establishing a proper connection state. In this state, various settings are performed by the switches arranged on the switch board 21 of the processor 2.

(Various settings by processor) Various settings will be described later for each setting item.

When the various settings are completed, the old data is deleted and the arm band is worn on the subject. In this state, the sphygmomanometer main body 1
Is removed from the processor 2 and the automatic measurement switch 8c of the sphygmomanometer main body 1 is turned on. As a result, the blood pressure can be measured, and the start / stop switch of the sphygmomanometer main body 1 is pressed to enable the automatic measurement.

Thereafter, the sphygmomanometer main body 1 performs blood pressure measurement based on a preset program, stores each measurement result, and connects the processor 2 again after the blood pressure measurement is completed, so that the processor prints out data. Do.

At the time of automatic measurement, the pump unit in the sphygmomanometer main body 1 operates at the scheduled time based on data set in advance. The air discharged from the pump unit is supplied to a cuff worn on the subject, tightens his / her arm so that blood pressure can be measured, and then exhausts air. During this time, the measurement of the pulse, the systolic blood pressure and the diastolic blood pressure are performed, and when the condition setting is set to display the measured value, the measured value is displayed on the display unit 5. When the display is not set, the time is displayed as in the non-measurement time. All the measurement data are stored in the memory mechanism regardless of whether or not they are displayed on the display unit 5.

If it is necessary to perform measurement in a mode other than this mode during the measurement in the automatic measurement mode, the event switch 8b is turned on. Thereby, for example, at the time of medication, immediately after a meal, at the time of going to bed, at the time of getting up, and the like, it is possible to immediately measure the blood pressure even when the time is difficult to set in advance. The data measured at intervals other than the preset interval is marked at the time of data printout to indicate that the data is measured data other than the set time.

Next, the various settings shown in FIG. 3A will be specifically described. Since various settings are all performed by the processor, it is natural that the blood pressure monitor main body 1 and the processor 2 are connected as shown in FIG.

(Setting of Measurement Interval) In FIG. 4, when the sphygmomanometer main body 1 and the processor 2 are connected and no setting has been made yet, a clock on which the time at that time is displayed on the display unit 22 of the processor 2 is displayed. The display mode is set.

First, the start time is set using the set switch S6 of the processor 2.

Next, the measurement interval is set using the set switch S6. The setting is performed in units of minutes, for example, at intervals of 15 minutes, 30 minutes, and the like. After setting a predetermined value, the selection switch S5 is pressed to confirm the set value.

Next, a section is set. Setting a section means dividing a 24-hour period into several sections and setting a measurement interval for each section. For example, when awake, there is a lot of external stimulus and exercise is taking place, so the blood pressure changes sharply.However, since there is no significant change in blood pressure when going to bed, shorten the interval between blood pressure measurements when awake, and increase the measurement interval when going to bed. And so on.

 The following is an example of the measurement interval setting.

9: 00 ~ 23: 15 interval 23: 00 ~ 7: 30 next morning interval 7: 00 ~ 9: 15 interval After selecting the measurement interval for each section, set the measurement end time and press the registration switch S8 The data is registered and the data is output to the sphygmomanometer main body 1 side.

(Setting of Condition) A method of setting a condition will be described with reference to FIG.

First, the processor 2 is set to the condition setting input mode by pressing the condition setting switch S2. As a result, the display unit 22 enters a mode for displaying setting conditions such as a display of a measured value from a clock display. Here, the display of the measured value means that when the blood pressure monitor main body 1 measures the blood pressure, the measurement result is displayed on the display unit 5 of the blood pressure monitor main body 1. The setting of the condition is performed using the set switch S6 and the selection switch S8. If the user selects whether to display the measured value, the user sets whether to sound the buzzer at the start of measurement. Next, the ID number is set. This setting is for specifying the subject, and for specifying the subject to which the printed out data belongs. For example, when a doctor lends a plurality of sphygmomanometer bodies 1 to a large number of patients and performs automatic measurement, a different ID number is assigned to each sphygmomanometer body 1.
The measurement data printed out and the person to be measured can be easily specified by inputting the information to the user. When these settings are completed, registration is performed, and the set condition data is output to the sphygmomanometer main body 1 side.

When the various settings described above are completed, the sphygmomanometer main body 1 into which the data has been input is mounted on the subject. Thereafter, the sphygmomanometer main body 1 automatically measures the blood pressure based on the setting items output from the processor 2.

(Printing of measurement data) When the automatic measurement is completed, print out the stored measurement data.

 This procedure will be described with reference to FIG.

The contents to be printed are, for example, (a) each measurement data is sequentially printed numerically (hereinafter, "table print").
(B) a mode in which each measurement data is displayed in a graph (hereinafter, referred to as “graphic print”), and (c) a printout based on what condition setting the measurement was made (hereinafter, “setting contents”). Print ")
A print mode such as a print mode is set in advance.

First, the sphygmomanometer main body 1 having completed the measurement and the processor 2 are connected again. Next, the print switch S3 of the processor 2
To ON. As a result, the first sequence content (table print) is displayed on the display unit 22 of the processor 2. If table printing is desired, pressing the start button S8 in this state starts table printing.

FIG. 8 shows an example of a table printout. 1 / 5'88 ID.1 at the top of the print is 198 when measured
On January 5, 2008, it shows that the ID number of the measurer is 1.

From the next stage, the measurement results of the sphygmomanometer main body are shown,
For example, the printout of the 24th measurement data shown below 24 23: 36 132 77 94 * indicates the following items.

That is, the 24th measurement, measurement time 23:36, systolic blood pressure
132, diastolic blood pressure 77, pulse rate 94, and the last item in the EV column * This measurement is not a measurement based on the preset items (time interval). Pressing the event switch 8b of the main body 1 indicates that the measurement is made by one's own will.

In the ERR section, if there is an error during blood pressure measurement, the content of the error is indicated by a code number. For example, errors include (a) microphone disconnection, poor contact, (b) air leak, (c) measurement failure due to reduced voltage, (d) poor recognition of Korotkoff sounds, (d) pulse less than 40 nights or 200 nights Above, (e) minimum blood pressure is 160mmHg or more,
(F) Various cases such as a systolic blood pressure of 60 mmHg or less are possible. Each of these errors is given a specific code number to clarify the content of the error.

At the end of the printout, INTERVAL1 ~ ...
The average value of the systolic blood pressure, the diastolic blood pressure, and the pulse for each set section is displayed. Then, finally, the average value of the systolic blood pressure, the diastolic blood pressure, and the pulse during the automatic measurement period is displayed as TOTAL.

Next, returning to FIG. 6, when the first sequence (table print) is not desired, the selection switch S5 is pressed to display the second sequence content (graphic print). If this print is desired, the print start time is set by pressing the set switch S6, and then the graphic print is performed by pressing the start switch S8. Thus, printing is performed on data after the print start time. FIG. 10 shows an example of a graphic print, in which each measurement data is displayed as a bar graph. The numbers 50 and 100 to 250 on the horizontal axis indicate blood pressure values, and the vertical axes 18, 20, 0, 2,..., 16 indicate measurement times.

Further, when it is desired to print out the setting contents, when the display of the second sequence contents is displayed, the selection switch S8 is further pressed to display the third sequence contents (setting contents print), and start at this time. Press switch S8. As a result, the settings output to the sphygmomanometer main body 1 before the start of the blood pressure measurement are output.

 FIG. 9 shows an example of a setting content printout.

The printout of the illustrated setting example indicates the following.

The top row shows the date and time of measurement and the ID number.
Hours to 23:00 indicate that the measurement interval is 15 minutes, 23 to 6:00 indicate that the measurement interval is 30 minutes, and 6 to 18:00 indicate that the measurement interval is 15 minutes. DISPLAY ON and BEEP O
"N" means that the measurement data was displayed on the display unit 5 at the time of measurement and the buzzer was set to sound.

(Setting of measurement mode at any time) As described above, various settings are premised on automatic measurement by the sphygmomanometer main body 1. One of the major features of the present invention is that the sphygmomanometer main body 1 and the processor 2 are shown in FIG. It can be used as a normal sphygmomanometer of the measurement type at any time when connected as shown.

A case where the blood pressure monitor is used as a measurement-type blood pressure monitor at any time will be described with reference to FIG.

First, the sphygmomanometer main body 1 and the processor 2 are connected. Thereafter, as shown in FIG. 2, the integrated state is used as one blood pressure monitor. All subsequent operations are performed using switches on the processor 2 side. First, by turning on the blood pressure measurement switch S4, the mode is set so that the apparatus operates as a measurement-type blood pressure monitor as a whole as needed. In this state, if a state in which blood pressure can be measured by wearing the arm band on the subject is set, the start switch S8 is turned ON. Thereby, the blood pressure measurement is started. To stop the measurement, turn the stop switch ON. In the configuration shown in FIG. 2, when the start switch S8 is pressed again, it operates as a stop switch. Pressing the stop switch sounds a buzzer and stops the measurement. When the switch S8 is pressed again, the blood pressure measurement is started again.
When the measurement is completed, the measured values (systolic blood pressure, diastolic blood pressure, pulse, etc.) are displayed, and the measured data is printed out.

The method of using the device in the manual measurement mode includes a case in which a doctor or a nurse carries the patient to measure the blood pressure of each patient, or a case in which the patient measures the blood pressure as appropriate while being locked to the bedside of each patient. Can be considered.

In addition, regardless of automatic measurement and occasional measurement, it is also possible to output measurement data to an arithmetic device such as a personal computer to perform various graphic displays and analysis.

〔effect〕

As specifically shown in the configuration, the present invention comprises a small and lightweight portable sphygmomanometer main body, and a processor formed integrally with the sphygmomanometer main body, and an input for performing various settings and the like at the time of measurement. Since all parts are installed on the processor side, the main body of the sphygmomanometer can be reduced in size and weight, and the handleability as a 24-hour automatic sphygmomanometer can be greatly improved.

The measured data can be printed in various modes by a printer built in the processor, and the measured data can be stored without using a special printing device.

Furthermore, by integrating the sphygmomanometer main body and the processor, it can be used as an occasional measurement type sphygmomanometer for manual measurement, and the application range of the device can be expanded compared to the conventional device dedicated to 24-hour measurement. it can.
