Description

The present invention relates to a sphygmomanometer that measures the blood pressure of a living body.

Equipped with a main body equipped with a pump and a cuff to which air is supplied from the pump, it is automatically operated by simply wrapping the cuff around the part to be measured such as the arm or wrist of the person to be measured and pressing the measurement switch. Sphygmomanometers that can measure blood pressure are known.

On the other hand, many studies have been conducted on the relationship between temperature and blood pressure fluctuations, and it is recognized that blood pressure tends to increase when the temperature is low. In particular, it is known that blood pressure may fluctuate when the temperature drops sharply. Therefore, a sphygmomanometer equipped with a temperature sensor for measuring the air temperature has been developed so that the person to be measured can easily know the air temperature in the measurement environment when measuring the blood pressure.

For example, Patent Document 1 describes a sphygmomanometer in which a temperature measuring unit for measuring the temperature of a measuring environment is housed inside a case body of the main body.

Further, in Patent Document 2, a temperature sensor is provided inside the main body case so as to be located on the path of the air flow into which air is introduced by the pump, and when the pump is operated for blood pressure measurement, the pump is concerned. A sphygmomanometer that measures the temperature of the air introduced inside the main body case as the temperature of the measurement environment is described.

However, in the conventional sphygmomanometer described in Patent Document 1, since the case body is sealed to the outside, the temperature inside the case body reaches a temperature that matches the temperature outside the case body. It will take time. Therefore, there is a problem that the temperature of the measurement environment cannot be accurately measured depending on the temperature measuring unit arranged inside the case body, especially when the air temperature changes suddenly.

On the other hand, like the conventional sphygmomanometer described in Patent Document 2, when the pump operates, the temperature of the air introduced into the main body case by the pump is measured as the air temperature of the measurement environment. With the meter, even when the temperature changes suddenly, the temperature of the measurement environment after the change can be measured. However, in this case, since it is necessary to measure the air temperature in a short time when the pump is operating, it is necessary to use an expensive temperature sensor having high responsiveness, which causes a problem that the cost increases.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a sphygmomanometer capable of accurately measuring the air temperature in a measurement environment with an inexpensive configuration.

In the sphygmomanometer of the present invention, in the above configuration, it is preferable that the temperature sensor periodically measures the air temperature regardless of whether or not the pump is operated.

In the above configuration, the sphygmomanometer of the present invention has a storage unit that stores the measured value of the temperature sensor, and the temperature based on the current measured value of the temperature sensor and the past measured value stored in the storage unit. It is preferable to have a temperature change detecting unit for detecting the change in the temperature change.

A power source such as a dry battery is housed inside the protruding case 32 of the case body 30. The power supply supplies electric power necessary for its operation toward the control unit 23, the display unit 25, the pump 26, and the like.

As shown in FIG. 5, the control unit 23 is provided in the accommodation space S of the case body 30 on the side opposite to the portion where the left and right side portions thereof are supported by the counters 34 and the display unit 25 of the display unit support 33 is supported. It is contained. The temperature sensor 28 is mounted on the control board constituting the control unit 23 and is housed in the storage space S inside the case body 30. The temperature sensor 28 can measure the temperature of the air inside the accommodation space S as the air temperature outside the case body 30. The temperature sensor 28 is not limited to the form mounted on the control board constituting the control unit 23, and may be housed in the accommodation space S in another form.

As shown in FIGS. 1 and 3 to 5, the case body 30 is provided with an outside air introduction hole 40 for communicating the storage space S accommodating the temperature sensor 28 to the outside of the case body 30. In the present embodiment, outside air introduction holes 40 are provided on a plurality of surfaces of the case body 30, that is, on the right side surface 31c and the left side surface 31d of the main case 31, respectively.

As shown in FIG. 3, 12 slit-shaped outside air introduction holes 40 are provided on the right side surface 31c of the main case 31. These outside air introduction holes 40 extend in a direction parallel to the top surface 31e between the back surface 31a and the front surface 31b of the main case 31, and are provided side by side at equal intervals between the top surface 31e and the bottom surface 31f. .. Similarly, as shown in FIG. 4, 12 slit-shaped outside air introduction holes 40 are provided on the left side surface 31d of the main case 31. These outside air introduction holes 40 extend in a direction parallel to the top surface 31e between the back surface 31a and the front surface 31b of the main case 31, and are provided side by side at equal intervals between the top surface 31e and the bottom surface 31f. .. As described above, 12 slit-shaped outside air introduction holes 40 are provided symmetrically on the right side surface 31c and the left side surface 31d of the case body 30 facing each other. In FIGS. 1, 3 and 4, for convenience, only one outside air introduction hole 40 is designated by a reference numeral.

In the sphygmomanometer 1 of the present embodiment, since the case body 30 is provided with the outside air introduction hole 40, the outside air introduction hole 40 is not trapped in the accommodation space S of the case body 30. It can always be ventilated by the outside air introduced from 40. In particular, when the temperature of the air in the accommodation space S of the case body 30 is different from the air temperature outside the case body 30, the air in the accommodation space S of the case body 30 is the outside air due to the convection naturally generated by the temperature difference. Is ventilated. That is, by providing the outside air introduction hole 40 in the case body 30, the air inside the accommodation space S is ventilated with the outside air by natural circulation without using a forced circulation means such as a fan.

With such a configuration, in the sphygmomanometer 1 of the present embodiment, the temperature of the air inside the accommodation space S of the case body 30 can be adjusted as compared with the case where the case body 30 is not provided with the outside air introduction hole 40. It is possible to quickly approach the outside temperature of 30. In particular, even if the temperature around the sphygmomanometer 1 changes due to a change in the temperature of the place where the sphygmomanometer 1 is placed or the sphygmomanometer 1 is moved to a place with a different temperature. The temperature of the air inside the accommodation space S of the body 30 can be quickly brought close to the air temperature outside the case body 30. Therefore, the temperature sensor 28 housed in the storage space S of the case body 30 can accurately measure the air temperature around the blood pressure monitor 1 outside the case body 30.

As described above, in the sphygmomanometer 1 of the present embodiment, since the outside air introduction hole 40 is provided in the case body 30, the temperature around the sphygmomanometer 1 is measured by the temperature sensor 28 housed in the storage space S of the case body 30. Can be measured accurately. Therefore, the sphygmomanometer 1 can be made capable of accurately measuring the air temperature in the measurement environment with an inexpensive configuration without using an expensive temperature sensor 28 having high responsiveness.

In particular, since the wrist type or integrated type such as the blood pressure monitor 1 of the present embodiment is easy to carry, the subject carries the blood pressure monitor 1 and the temperature differs greatly before the blood pressure is measured. It is possible to move to another place. On the other hand, according to the sphygmomanometer 1 of the present embodiment, even when the temperature around the sphygmomanometer 1 changes, the sphygmomanometer 28 is accommodated in the accommodation space S of the case body 30. It is possible to accurately measure the temperature after the change in the surroundings of 1.

Then, according to the sphygmomanometer 1 of the present embodiment, based on the above measurement result, whether or not the ambient air temperature when measuring the blood pressure, that is, the temperature of the measurement environment is suitable for the blood pressure measurement by the control unit 23. It is possible to determine whether or not, and notify the person to be measured of the determination result. Therefore, the convenience of the person to be measured who uses the sphygmomanometer 1 can be enhanced.

The sphygmomanometer 1 of the present embodiment has a configuration in which the temperature sensor 28 is housed inside the case body 30, and can accurately measure the changed air temperature around the sphygmomanometer 1. Therefore, according to the sphygmomanometer 1 of the present embodiment, the temperature sensor 28 can be protected by the case body 30 to prevent the temperature sensor 28 from being damaged.

Further, in the sphygmomanometer 1 of the present embodiment, since the outside air introduction holes 40 are provided on the right side surface 31c and the left side surface 31d of the case body 30, the outside air introduction holes provided on the right side surface 31c of the accommodation space S are provided. The region between the 40 and the outside air introduction hole 40 provided on the left side surface 31d can be formed as a flow path through which the outside air flows. As a result, the air inside the accommodation space S is more efficiently ventilated with the outside air, and the temperature sensor 28 accommodated in the accommodation space S of the case body 30 measures the air temperature around the sphygmomanometer 1 more accurately. be able to.

In the present embodiment, the outside air introduction holes 40 are provided on the right side surface 31c and the left side surface 31d of the case body 30, but if the outside air introduction holes 40 are provided on a plurality of surfaces of the case body 30. , The arrangement can be changed in various ways. For example, the outside air introduction holes 40 may be provided on a pair of surfaces of the case body 30 facing each other, that is, on the top surface 31e and the bottom surface 31f, or may be provided on the front surface 31b and the back surface 31a. Further, the outside air introduction hole 40 is formed on a pair of surfaces of the case body 30 adjacent to each other, such as the right side surface 31c and the bottom surface 31f, the right side surface 31c and the top surface 31e, the right side surface 31c and the front surface 31b, and the right side surface 31c and the back surface 31a. It may be provided. Further, the outside air introduction hole 40 may be provided on a pair of surfaces of the case body 30 facing each other and a surface adjacent to the pair of surfaces. Further, the outside air introduction holes 40 may be provided on three or more surfaces of the case body 30. With these configurations as well, similarly to the above, the region between the outside air introduction holes 40 provided on each surface is formed in the flow path through which the outside air flows, and the air inside the accommodation space S is more efficiently combined with the outside air. Can be ventilated.

Further, in the sphygmomanometer 1 of the present embodiment, since a plurality of outside air introduction holes 40 are provided in each of the right side surface 31c and the left side surface 31d of the case body 30, the air inside the accommodation space S can be more efficiently used. It can be ventilated with the outside air. Therefore, the temperature around the sphygmomanometer 1 can be measured more accurately by the temperature sensor 28 housed in the storage space S of the case body 30.

Further, in the sphygmomanometer 1 of the present embodiment, since the plurality of outside air introduction holes 40 provided in each of the right side surface 31c and the left side surface 31d of the case body 30 are slit-shaped, a plurality of outside air introduction holes in each surface are introduced. While ensuring a large total opening area of the holes 40, it is possible to prevent foreign matter from entering the inside of the accommodation space S from the outside air introduction holes 40.

In order to prevent foreign matter from entering the accommodation space S from the outside air introduction hole 40, the partition wall 33a may be provided inside the accommodation space S. As shown in FIG. 5, the partition walls 33a are integrally provided at both ends of the display unit support 33 as a part of the display unit support 33, and a predetermined interval is provided inside the corresponding outside air introduction holes 40. Are arranged facing each other. With such a configuration, it is possible to prevent the invasion of foreign matter from the outside air introduction hole 40 toward the inside of the accommodation space S by the partition wall 33a, and effectively prevent the blood pressure monitor 1 from being damaged by the foreign matter.

Further, it is also possible to more reliably prevent the invasion of foreign matter from the outside air introduction hole 40 toward the inside of the accommodation space S by the counter 34. In the present embodiment, the strut 34 is arranged inside the partition wall 33a so as to be offset from the front surface 31b with respect to the partition wall 33a. With such a configuration, the invasion of foreign matter from the outside air introduction hole 40 toward the inside of the accommodation space S is more reliably prevented by the counter 34, and the blood pressure monitor 1 is more effectively suppressed from being damaged by the foreign matter. be able to.

The temperature sensor 28 can be configured to periodically measure the air temperature regardless of whether the pump 26 is operating or not. In the present embodiment, the temperature sensor 28 is used at predetermined time intervals in the background even when the power of the sphygmomanometer 1 is off before the blood pressure is actually measured by the sphygmomanometer 1. For example, the temperature is periodically measured every minute) and input to the control unit 23.

Since the air in the accommodation space S of the case body 30 is always ventilated with the outside air through the outside air introduction hole 40, the temperature of the air in the accommodation space S of the case body 30 has already reached the temperature outside the case body 30 before measuring the blood pressure. The temperature is close. Therefore, as described above, by performing the measurement by the temperature sensor 28 on a regular basis, the temperature of the accommodation space S, that is, the temperature outside the case body 30 can be accurately measured before the blood pressure is measured. Therefore, the temperature of the measurement environment can be quickly notified to the person to be measured when the blood pressure measurement is started without using an expensive temperature sensor 28 having high responsiveness.

Further, when the temperature sensor 28 is configured to measure the temperature periodically, the measured value of the temperature sensor 28 is stored in the storage unit 24, and the current measured value of the temperature sensor 28 and the storage unit 24 are stored. It is also possible to detect a change in the ambient temperature of the blood pressure monitor 1 based on the past measured values. In this case, the control unit 23 has a function as the temperature change detection unit 50 as an internal function, and the current measurement value of the temperature sensor 28 in the temperature change detection unit 50 and the past measurement value stored in the storage unit 24. It can be configured to calculate the change in the ambient temperature of the sphygmomanometer 1 based on the above. Even if the temperature change detection unit 50 is configured to calculate the change in the ambient temperature of the sphygmomanometer 1 based on the current measurement value of the temperature sensor 28 and the previous measurement value stored in the storage unit 24. Well, or it may be configured to calculate the change in the ambient temperature of the sphygmomanometer 1 based on the current measurement value of the temperature sensor 28 and the past multiple measurement values stored in the storage unit 24. ..

When the amount of change in air temperature detected by the air temperature change detection unit 50 becomes equal to or greater than a predetermined threshold value, the control unit 23 determines that the amount of change in air temperature is abruptly unsuitable for measuring blood pressure. The determination is performed in the background even when the power of the sphygmomanometer 1 is off.

When the control unit 23 determines that the amount of change in temperature obtained by the temperature change detection unit 50 is a sudden amount of change that is not suitable for measuring blood pressure, the control unit 23 warns the display unit 25 that the temperature has changed suddenly. By displaying or generating a warning sound, it is possible to warn the person to be measured that the temperature in the measurement environment has changed suddenly to the extent that it is not suitable for measuring blood pressure. That is, when the temperature change detection unit 50 detects a sudden change in blood pressure, the sphygmomanometer 1 measures the blood pressure and displays a warning that the measurement environment is not suitable for the blood pressure measurement. It can be configured to be displayed on 25 or to generate a warning sound to notify the person to be measured. When the temperature change detection unit 50 detects a sudden change in temperature, the sphygmomanometer 1 does not measure the blood pressure by the subject, and the temperature in the measurement environment is an appropriate temperature or temperature change. It is also possible to configure the temperature measurement to be feasible only when it is in the category.

In particular, since the wrist-type or integrated sphygmomanometer 1 such as the sphygmomanometer 1 of the present embodiment is easy to carry, the sphygmomanometer 1 is carried by the person to be measured and the temperature rises before the blood pressure is measured. It may be moved to a different location. On the other hand, if the sphygmomanometer 1 is configured to include the above-mentioned temperature change detection unit 50, the temperature change detection unit determines whether or not the amount of change in temperature due to movement is a sudden amount of change that is not suitable for measuring blood pressure. It is possible to make an accurate judgment by 50 and promptly notify the person to be measured.

The above determination by the temperature change detection unit 50 is executed in the background even when the power of the sphygmomanometer 1 is off. Therefore, as soon as the person to be measured turns on the power of the sphygmomanometer 1, it is possible to notify the person to be measured that the amount of change in air temperature due to movement is a sudden amount of change that is not suitable for measuring blood pressure.

The sphygmomanometer 1 having the above configuration can measure the blood pressure of the person to be measured by the following procedure.

First, the cuff 10 is wrapped around the wrist of the person to be measured and fixed.

Next, when the operation switches 21 and 22 are operated to turn on the power, the control unit 23 and the air temperature change detection unit 50 determine whether or not the air temperature in the measurement environment and the change in air temperature are suitable for measuring blood pressure. If it is judged and the temperature or change in temperature is not suitable for measuring blood pressure, a warning will be issued.

On the other hand, when the control unit 23 and the air temperature change detection unit 50 determine that the air temperature or the change in air temperature is suitable for measuring blood pressure, the measurement is started by operating the operation switches 21 and 22. Can be done.

When the blood pressure measurement is started, the pump 26 is operated under the control of the control unit 23, air is injected from the pump 26 into the cuff 10, the cuff 10 is pressurized, and the wrist is pressed by the cuff 10. The sphygmomanometer 1 is based on the internal pressure at which the pulse detected by the pressure sensor 27 is generated and extinguished in the process in which the wrist is gradually compressed by the cuff 10, that is, by a pressurized oscillometric method. To measure. When the cuff 10 is pressurized to the extent that the pulse on the wrist disappears, the blood pressure measurement is completed, the operation of the pump 26 is stopped, the valve mechanism is opened, and the pressure on the wrist by the cuff 10 is released.

When the blood pressure measurement is completed, the measurement result is displayed on the display unit 25 and stored in the storage unit 24 as past data.

It goes without saying that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist thereof.

For example, in the above-described embodiment, the sphygmomanometer 1 is a wrist type or an integrated type, but the present invention is not limited to this. For example, the sphygmomanometer 1 may have a separate type configuration in which the main body 20 is connected to the cuff 10 via an air tube. Alternatively, the sphygmomanometer 1 is a stationary type in which the main body 20 is integrally provided with a cylindrical insertion tube through which the upper arm can be inserted into the case body 30, and the cuff 10 is provided along the inner surface of the insertion tube. It may be a thing.

Further, the shape of the case body 30 can be changed in various ways.

Further, the number, shape, and arrangement of the outside air introduction holes 40 provided in the case body 30 can be variously changed.
