DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an electronic sphygmomanometer.

[0002]

2. Description of the Related Art Conventionally, an electronic sphygmomanometer of a reduced pressure measurement type has been
In order to block blood at the blood pressure measurement site, pressurized air is supplied from a pressurized pump to a cuff wound around an arm, a wrist, or the like. When the pressure in the cuff reaches a specified pressure, the supply of pressurized air from the pressurizing pump is stopped, the pressurized air is exhausted at a very low speed from the exhaust valve, and the pressure in the cuff is detected by a pressure sensor during this exhaust. At the same time, the pulse wave component is detected from this pressure, and the maximum and minimum blood pressure values are calculated from the pulse wave component and the cuff pressure. That is, as shown in FIG. 13, pressurized air is supplied to a cuff 1 wound around an arm, a wrist, or the like from a pressurizing unit 2, for example, a pressurizing pump, so that the arm, the wrist, or the like is blocked. After the pressure reaches a certain specified pressure, the pressurized air is exhausted at a very low speed from the exhaust means 3, for example, an exhaust valve, and the blood pressure measuring means 4 calculates the maximum and minimum blood pressure values during the exhaust at a low speed.

In the early stage of measurement, the inside of the cuff is pressurized to a predetermined pressure. However, since the blood pressure value varies depending on the user, the pressurization is insufficient at the predetermined pressure value. There are cases. For example, if the pressure has not been increased to the systolic blood pressure value, the blood pressure measurement cannot be performed. Therefore, when it is determined that the pressurization is insufficient, re-pressurization of, for example, 30 mmHg is uniformly performed so that even a user having a high systolic blood pressure value can correctly measure the blood pressure.

[0004]

However, in the above-mentioned conventional electronic blood pressure monitor, if the blood pressure is not increased to the maximum blood pressure even after the re-pressurization, the re-pressurization must be performed again. Measurement requires time, and the subject is to be pained for a long time.

In the case of insufficient pressurization, for example, 30
Since the re-pressurization of mmHg is performed, the pressure may be excessively increased depending on the blood pressure value of the user, and a long time is required for the measurement.

Further, since the pressurization is unconditionally increased to a predetermined value, in the case of a user having a low systolic blood pressure value, the user is overpressurized, and the body is excessively pressurized. There is a problem that stress is applied and measurement takes time.

[0007]

In order to solve the above-mentioned problems, the present invention provides a cuff, and pressurizing means for supplying pressurized air to the cuff up to a pressurized value set by pressurized value setting means. An evacuation unit for evacuating pressurized air in the cuff at a low speed, a blood pressure measurement unit for measuring a blood pressure during the evacuation at a low speed, and a plurality of storage units for storing a measurement result calculated by the blood pressure measurement unit. The setting means determines the pressure value from a plurality of contents of the storage means.

According to the invention, the current pressurization value is determined from the contents of the plurality of storage means storing the past measurement results,
By pressurizing based on this, pressurization can be performed at an optimum pressurization value suitable for the user.

For example, for a user with high blood pressure, unnecessary re-pressurization is suppressed, so that stress on the body and mental distress can be reduced, and the measurement time can be shortened. Accordingly, the battery life of the product can be extended, and the life of components such as the pump can be extended.

Conversely, for a user with low blood pressure, excessive pressurization can be suppressed, so that stress on the body and mental distress due to ischemia can be reduced, and the measurement time can be shortened. Accordingly, the battery life of the product can be extended, and the life of components such as the pump can be extended.

[0011] Further, a cuff and pressurizing means for supplying pressurized air to the cuff up to a pressurized value set by the pressurized value setting means,
Exhaust means for evacuating pressurized air in the cuff at a very low speed; blood pressure measuring means for measuring blood pressure during the very low speed evacuation; a plurality of storage means for storing the measurement results calculated by the blood pressure measuring means; Determining means for determining whether to use the pressure value, wherein the pressure value setting means switches the pressure value calculated from a plurality of contents of the storage means by the determining means.

[0012] According to the above invention, the determining means determines whether or not individual use is performed, and switches the method of determining the pressurization value between individual use and multiple use, so that it is more suited to actual use. Since it is possible to pressurize at an optimum pressurization value, stress on the body and mental distress due to ischemia can be reduced, and the measurement time can be shortened.

Accordingly, the battery life of the product can be extended, and the life of components such as the pump can be extended.

Conversely, for a user with a low blood pressure, excessive pressurization can be suppressed, so that stress on the body and mental distress due to ischemia can be reduced, and the measurement time can be shortened. Accordingly, the battery life of the product can be extended, and the life of components such as the pump can be extended.

Further, the pressurized value setting means has a maximum value calculating means for calculating a maximum value of a plurality of contents of the storage means, and a fixed value determined in advance by the value calculated by the maximum value calculating means. The value obtained by adding the values is used as the current pressure value.

Since the pressurization value is determined based on the maximum value of the plurality of contents of the storage means, even if the blood pressure fluctuates due to breathing or the like, the pressure is increased to the maximum value of the past measurement result + α. Excessive re-pressurization can be suppressed as compared with fixed-value pressurization, and blood pressure can be measured more comfortably.

Further, the pressurized value setting means includes an average value calculating means for calculating an average value of a plurality of contents of the storage means, and a fixed value predetermined by the average value calculating means. The value obtained by adding the values is used as the current pressure value.

Since the pressure value is determined based on the average value of the plurality of contents of the storage means, the influence of the blood pressure fluctuation is less than in the case where the pressure value is determined from the contents of one storage means. Blood pressure can be measured more comfortably.

Further, a cuff, pressurized value setting means, pressurizing means for supplying pressurized air to the cuff up to a pressurized value set by the pressurized value setting means, and pressurized air in the cuff Exhaust means for evacuation of blood at a low speed, blood pressure measurement means for measuring blood pressure during the evacuation at a low speed, a plurality of storage means for storing measurement results calculated by the blood pressure measurement means, and whether to use for personal use or for a plurality of people Determination means, wherein the pressure value setting means,

The determination means determines whether or not the blood pressure is for personal use, and switches the method of determining the pressurization value between personal use and multiple use, so that blood pressure measurement can be performed in accordance with the actual use condition. Since the pressurization can be performed at the optimum pressurization value, stress on the body and mental distress due to ischemia can be reduced, and the measurement time can be shortened.

Further, the determining means has setting means which can be switched by a user, and the setting means determines whether the setting is for personal use or for use by a plurality of persons.

[0024] By determining whether to use the device for personal use or for multiple users by setting means that can be switched by the user, the use of the device can be determined more reliably. Therefore, the blood pressure can be measured in accordance with the actual condition of use. Since the pressurization can be performed at the optimum pressurization value, stress on the body and mental distress due to ischemia can be reduced, and the measurement time can be shortened.

Furthermore, the determining means determines that the personal use is performed when the distribution of the plurality of contents of the storage means is within a certain predetermined range, and determines that the use is performed by a plurality of persons when the distribution is out of the predetermined range. It is.

Then, the determination of the personal use or the use of a plurality of persons is determined as the personal use when the distribution of the plurality of contents of the storage means is within a certain predetermined range, and as the use of plural persons when the distribution is out of the predetermined range. By doing so, it is possible to judge individual use without increasing the number of parts, so that blood pressure measurement can be performed according to the actual use and pressurization can be performed at the optimal pressurized value, resulting in stress and mental The pain can be reduced and the measurement time can be reduced.

Further, the pressurizing value setting means has a maximum value calculating means for calculating a maximum value of a plurality of contents of the storage means. Is a value obtained by adding a predetermined fixed value to the value calculated by the maximum value calculating means.

Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1) FIG. 1 is a configuration block diagram of an electronic sphygmomanometer according to Embodiment 1 of the present invention. Pressurized air is supplied to the wound cuff 1 such as an arm or a wrist from a pressurizing means 2, for example, a pressurizing pump, and the inside of the cuff 1 is pressurized to a predetermined pressure to block the blood of the arm or the wrist. Is exhausted at a very low speed from the exhaust means 3, for example, an exhaust valve, and the blood pressure is calculated by the blood pressure measuring means 4 during the exhaust. The past measurement result, for example, the systolic blood pressure value is stored in the plurality of storage means 5, and the pressure value setting means 6
An optimum pressure value is determined from a plurality of systolic blood pressure values stored in the storage means 5.

In general, an electronic sphygmomanometer is configured to pressurize the inside of the cuff to a predetermined pressure in the initial stage of measurement, and then calculate the blood pressure value by evacuating the pressurized air at a very low speed. Since the pressure varies depending on the measurer, as shown in FIG. 2, when the pressure is insufficient, for example, when the pressure is not increased to the systolic blood pressure value, the blood pressure measurement cannot be performed. Therefore, when it is determined that the pressurization is insufficient, re-pressurization of, for example, 30 mmHg is uniformly performed so that even a user having a high systolic blood pressure value can correctly measure the blood pressure.

However, as shown in FIG. 3, when the blood pressure has not been increased to the systolic blood pressure even after the re-pressurization, the re-pressurization must be performed again, which takes time for the measurement, and This will cause long-term pain to the measurer. In addition, in a wrist-type electronic blood pressure monitor or the like, the measurement time tends to be longer for accurate detection of a pulse.

In the case of insufficient pressurization, for example, 30
Since the re-pressurization of mmHg is performed, the pressure may be excessively increased depending on the blood pressure value of the user. Further, since the pressurization is unconditionally pressurized to a predetermined value, as shown in FIG. 4, in the case of a user having a low systolic blood pressure value, excessive pressurization is performed, Excessive stress was applied to the body, and measurement took time.

That is, as shown in FIG. 5, in the case of the fixed value pressurization, in the case of a user having a high systolic blood pressure value, re-pressurization may be performed several times, and the pressurization is performed more than the ideal pressurization. In some cases, the subject was accompanied by physical stress and mental distress.

For a user with a low systolic blood pressure,
The initial pressurization applied a pressure higher than the ideal pressurization, and was accompanied by physical stress and mental distress for the subject.

Therefore, the past measurement results are stored in the storage means 5, and an optimum pressure value is set by the pressure value setting means 6 from the stored several systolic blood pressure values, and based on the value. By applying pressure by the pressurizing means 2, even a subject whose systolic blood pressure value> (initial pressurization pressure + repressurization pressure) as shown in FIG. Blood pressure can be measured, unnecessary re-pressurization can be suppressed, and stress on the body and mental distress due to ischemia can be reduced. Further, by suppressing re-pressurization, the measurement time can be reduced. Accordingly, the battery life of the product can be extended, and the life of components such as the pump can be extended.

In the case of a subject whose systolic blood pressure value <initial pressurizing pressure as shown in FIG. 4, excessive pressurization can be suppressed by lowering the initial pressurizing pressure. It can reduce stress and mental distress. Further, by suppressing excessive pressurization, the measurement time can be reduced. Accordingly, the battery life of the product can be extended, and the life of components such as the pump can be extended.

Here, the contents stored in the storage means 5 are the systolic blood pressure values calculated by the blood pressure measurement means 4, but the present invention is not limited to this.

(Embodiment 2) FIG. 6 is a block diagram showing the configuration of an electronic sphygmomanometer according to Embodiment 2 of the present invention. The same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.

The pressurization value setting means 6 has a maximum value calculation means 7 for calculating the maximum value of some contents of the storage means, and a predetermined fixed value is set to the value calculated by the maximum value calculation means 7. Is added to the current pressurization value.

Further, since the blood pressure value fluctuates easily due to respiration, etc., the systolic blood pressure value may be high or low. Under these circumstances, when measured with an electronic sphygmomanometer that pressurizes to a predetermined pressurization value, repressurization is performed when the systolic blood pressure value is high, and excessive pressurization is performed when the systolic blood pressure value is low. This gives the subject a feeling of discomfort.

Therefore, the pressurization value setting means 6 is
By setting the maximum value + α of some measurement results stored in the “+” value as the current pressurization value, even if the blood pressure value fluctuates each time the measurement is performed, the maximum value of the calculated maximum blood pressure value can be measured. Since such a pressure value is set, the blood pressure can be measured comfortably without re-pressurization.

It should be noted that the maximum value calculation means 7 uses the storage means 5
May be used, or all may be used.

Although the embodiment in which the maximum value of the contents of the storage means 5 is used has been described here, the same effect can be obtained even if the pressure value is determined using a statistical method such as sigma. Can be

(Embodiment 3) FIG. 7 is a block diagram showing the configuration of an electronic sphygmomanometer according to Embodiment 3 of the present invention. Pressurization value setting means 6
Has an average value calculating means 8 for calculating an average value of some contents of the storage means 5, and adds a predetermined fixed value to the value calculated by the average value calculating means 8 to the current addition. The pressure value is used, and the pressure is applied by the pressurizing means 2 based on the value.

As described in the second embodiment, the blood pressure fluctuates due to various factors. Therefore, if the pressurization value is determined based on only one data stored in the storage unit 5, if the data at the time when a large fluctuation occurs is adopted, the pressurization value far from the original ideal pressurization value is used. Set to a value.

Therefore, the pressurized value setting means 6 uses the average value of the systolic blood pressure values up to the previous measurement + α as the current pressurized value, so that the influence of the fluctuation is minimized even if the blood pressure value fluctuates each time it is measured. As a result, the blood pressure can be measured comfortably even when the blood pressure value is high or low.

(Embodiment 4) FIG. 8 is a block diagram showing the configuration of an electronic sphygmomanometer according to Embodiment 4 of the present invention. The judging means 9 judges whether the use is for personal use or for a plurality of people. Pressurize at

By judging personal use and use by a plurality of persons by the judging means 9 and setting a pressurization value according to the judgment, an optimum pressurization value suitable for actual use can be set.
In addition, excessive pressurization and stress due to ischemia can be suppressed, and more comfortable blood pressure measurement can be performed.

(Embodiment 5) FIG. 9 is a block diagram showing the configuration of an electronic sphygmomanometer according to Embodiment 5 of the present invention. The judging means 9 has a setting means 10 which can be switched by the user, and judges whether the setting means 10 is for personal use or plural use. The current pressurization value is determined based on this value, and pressurization is performed by the pressurizing means 2 based on the value.

The setting means 10 is, for example, a switch, and enables a user to easily switch between personal use and use by a plurality of people.

As a result, it is possible to more reliably judge whether the personal use or the plural use is made by the judging means 9, and it is possible to set the optimum pressurization value in accordance with the actual use condition. Stress and mental distress can be reduced, and measurement time can be reduced.

(Embodiment 6) FIG. 10 is a block diagram showing the configuration of an electronic blood pressure monitor according to Embodiment 6 of the present invention. When the distribution of systolic blood pressure values, which is the content of the storage means 5, is within a certain range, the determination means 9 determines that the use is for personal use, and when the distribution is harmful, the use of multiple persons is determined. The current pressurization value is determined based on the result of the means 9, and the pressurization means 2 pressurizes based on the value.

As a result, it is possible to judge whether the personal use or the plural use is performed by the judging means 9 without increasing the number of parts, and it is possible to set the optimum pressurization value according to the actual use. Can reduce stress and mental distress on the body, and can shorten the measurement time.

(Embodiment 7) FIG. 11 is a block diagram showing the configuration of an electronic sphygmomanometer according to Embodiment 7 of the present invention. Pressurization value setting means 6
Has a maximum value calculating means 7 for calculating a maximum value from several systolic blood pressure values which are the contents of the storage means 5, and a determining means 9
The pressurizing value when it is determined that the personal use is determined as the value + α calculated by the maximum value calculating means 7, and the pressurizing means 2 pressurizes based on this value.

In addition, when used by individuals, the change in blood pressure value is smaller than when used by a plurality. From this, it is possible to set a more optimal pressurized value according to the actual use by judging personal use and pressurizing based on the maximum value of several systolic blood pressure values up to the previous measurement. Even if the blood pressure fluctuates each time it is measured, excessive re-pressurization is suppressed, and the blood pressure can be measured comfortably.

(Eighth Embodiment) FIG. 12 is a block diagram showing the configuration of an electronic sphygmomanometer according to an eighth embodiment of the present invention. Pressurization value setting means 6
Has an average value calculating means 8 for calculating an average value from several systolic blood pressure values which are the contents of the storage means 5, and a determining means 9
The pressurization value when it is determined that the personal use is determined as the value calculated by the average value calculation means 8 + α, and the pressurization means 2 pressurizes based on this value.

By determining personal use and applying pressure based on the average value of several systolic blood pressure values up to the previous measurement, the blood pressure fluctuations are greater than determining the pressure value using one data. It is hardly affected by the pressure and can set a more optimal pressurized value that matches the actual use.Also, even if the blood pressure fluctuates each time it is measured, excessive re-pressurization is suppressed and the blood pressure is comfortably controlled. Can be measured.

(Embodiment 9) The pressurizing value at the time of judging to use personally by the judging means 9 is set as the value previously stored in the storage means 5 and the pressurizing means 2 pressurizes based on this value. ,
It is possible to pressurize at an optimum pressurization value according to the actual use, and comfortable blood pressure measurement is possible.

(Embodiment 10) The pressurizing value when the judging means 9 judges that a plurality of persons are used is set to a predetermined fixed value, and the pressurizing means 2 pressurizes based on this fixed value. .

When a plurality of users, for example, a person having a high systolic blood pressure and a person having a low systolic blood pressure are disturbed and the blood pressure is measured, the calculated systolic blood pressure value is stored, and when the pressurizing value is changed accordingly, the pressurizing pressure is changed. If your value is pulled by people with high systolic blood pressure,
Conversely, the blood pressure may be pulled by a person having a low systolic blood pressure value, and the pressure value may be greatly biased.

Therefore, if pressure is applied at a predetermined pressure value, the blood pressure can be measured comfortably even when a plurality of users use it.
