Description

Biological information measuring device, biological information processing system, biological information measuring device, and control method for information processing terminal

The present invention belongs to the technical field related to healthcare, and relates to a biological information measuring device, a biological information processing system, a biological information measuring device, and a control method for an information processing terminal.

In recent years, it has become possible for individuals to routinely measure information about their bodies and health (hereinafter also referred to as biological information) by themselves using measuring devices, such as blood pressure values and electrocardiogram waveforms, and to utilize the measurement results for health management. It is becoming common practice. For this reason, there is an increasing demand for devices with emphasis on portability, and various portable measuring devices have been proposed (for example, Patent Documents 1 and 2).

Patent Document 1 discloses a portable electrocardiogram waveform measurement device used in conjunction with an information processing terminal such as a smartphone. According to the technology described in this document, it is possible to measure electrocardiographic waveforms with a device and stream the measured data to a smartphone, and it is possible to analyze the data acquired on the smartphone and use it effectively. can. Furthermore, Patent Document 2 discloses that a wristwatch-type wearable device that can be linked with an information processing terminal such as a smartphone measures blood pressure and electrocardiographic waveforms, and that during measurement of electrocardiographic waveforms, the display screen can display an electrocardiogram.

By the way, since the above-mentioned portable wearable device is a small device, there are many restrictions in terms of user interface. In this regard, according to the techniques described in Patent Documents 1 and 2, a device and an information processing terminal can be used in conjunction, and the information processing terminal can be used as a user interface.

Special table 2014-8713 publication US Patent Application Publication No. US2019/0072912

However, according to the technique described in Patent Document 1, there is a problem in that the device cannot measure electrocardiographic waveforms by itself, and must be used as a set with an information processing terminal. Furthermore, even with the technique described in Patent Document 2, there is a problem in that when the information processing terminal is displaying the measurement status and measurement results, the device cannot be operated at the same time.

Additionally, when performing (accurate) measurement of biological information with a device such as the one described above, it is generally necessary to wear the device and take an appropriate posture. However, there is a problem in that it is difficult for users who are not accustomed to using the device to take an appropriate posture for measuring biological information.

In view of the above-mentioned problems, the present invention relates to a biological information measuring device that can measure biological information such as blood pressure and electrocardiogram waveforms by itself, and also provides guidance on operating methods and operating conditions depending on the state of the device. The purpose of the present invention is to provide a technology that allows information to be output by other electronic devices such as information processing terminals.

In order to solve the above problems, the present invention employs the following configuration. That is,
A biological information measuring device that is used by being attached to the wrist of a human body,
Blood pressure measuring means for measuring the blood pressure of the human body;
an input means for accepting an operation to start measuring blood pressure of the human body;
an electrocardiographic waveform measuring means comprising a plurality of electrodes and for measuring an electrocardiographic waveform of the human body;
electrode contact state detection means for detecting a contact state of the human body to the plurality of electrodes;
position detection means for detecting the position of the device;
A control means for controlling the output of predetermined guidance information;
and a communication means for communicating with another electronic device including the first display means,
The control means includes:
When an operation to start blood pressure measurement of the human body is received via the input means, if communication between the device and the other electronic device is established, at least the one display means of the electronic device displays: a first height guide image that guides the wrist of the human body wearing the device to be located at a height within a predetermined range; and a first height guide image that guides the human body to an appropriate posture for contacting the plurality of electrodes. a 1-electrode contact guidance image, a first measurement image that guides that the blood pressure and/or the electrocardiogram waveform is being measured, and a first measurement result that shows the measurement result of the blood pressure and/or the electrocardiogram waveform. Controls the output of images and
This is a biological information measuring device characterized by the following.

Note that in this specification, "measuring electrocardiographic waveforms" refers to recording waveform data of electrocardiographic signals. Furthermore, examples of the above-mentioned blood pressure measuring means include, but are not limited to, cuffs, pressure sensors, pumps, etc. for measuring blood pressure using an oscillometric method. Further, as the position detection means, for example, a 3-axis acceleration sensor can be used, but other means may be used as long as it is possible to detect at least the position on the vertical axis of the device (that is, the height at which the device is located). May be used.

According to such a configuration, various guidance information can be displayed not on the small measuring device itself, but on other electronic devices that are communicatively linked. This allows the user to check the posture the user should take and the measurement results of biological information without having to check the output information of the measuring device in an unreasonable position.

In addition, the control means makes a first validity determination for determining whether the wrist of the human body wearing the device is located at a height within a predetermined range based on the output of the position detection means; carrying out a second validity determination of determining whether or not the human body is in stable contact with the plurality of electrodes based on the output of the electrode contact state detection means;
After receiving an operation to start measuring blood pressure of the human body through the input means, control is performed to output the first height guide image, and when the result of the first validity determination is true, the first height guide image is outputted. Control may be performed to output a one-electrode contact guidance image.

When attempting to measure blood pressure and electrocardiogram waveforms simultaneously using a device worn on the arm, the wrist with the device attached must be placed at a predetermined height for accurate blood pressure measurement, and then It is necessary to make stable contact with the electrode. However, it is difficult for users to grasp whether or not they are in the correct posture. In this regard, with the above configuration, the posture that the user should take is displayed on the display of the linked electronic device, and if the user can take the posture as displayed, the next posture that the user should take will be changed. will be displayed. According to this, users can understand whether or not they are able to take the correct posture and know what to do next in an orderly manner, making it possible to greatly improve usability. become.

Further, the control means is configured to measure the blood pressure of the human body by the blood pressure measuring means and to measure the blood pressure of the human body by the electrocardiogram waveform measuring means when the results of the first validity determination and the second validity determination are both true. The electrocardiographic waveforms may be measured all at once, and the first measuring image may be output during the measurement of the blood pressure and the electrocardiographic waveforms.

It should be noted that the term "all at once" here includes simultaneous and parallel execution. With this configuration, when you are in a position suitable for measuring blood pressure and electrocardiogram waveforms, you can automatically start measurements while maintaining a stable state, which reduces noise. It is possible to obtain highly accurate measurement results with less. In addition, while measuring biometric information, the user must maintain the same posture for a considerable period of time and wait for the measurement to finish, so having a display indicating that the measurement is in progress makes it easier to simply wait. Compared to this, the mental load on the user can be reduced.

Furthermore, the control means may perform control to output the first measurement result image after the measurement of the blood pressure and the electrocardiogram waveform is completed. According to this, the user can understand that the measurement has been completed by being able to display the measurement result, and can also confirm the measurement result using the highly visible display means.

Furthermore, the control means may control to simultaneously output the first height guide display and the first electrode contact guide image. For users who have become accustomed to operating the device, it may be troublesome to wait for the screen to change one by one each time. In this regard, with such a configuration, redundancy can be reduced because the orientation for measurement is guided using only one screen.

Further, the biological information measuring device has an output means including a second display means,
The control means includes a second height guide image for guiding the wrist of the human body wearing the device to be located at a height within a predetermined range, regardless of the presence or absence of communication with the other electronic device; a second electrode contact guidance image for guiding the human body to an appropriate posture for contacting the plurality of electrodes; and a second measurement-in-progress image for guiding that the blood pressure and/or the electrocardiogram waveform is being measured. , and a second measurement result image showing the measurement results of the blood pressure and/or the electrocardiographic waveform, from the second display means.

With such a configuration, various guidance displays can be output even when communication with other electronic devices is not established, that is, even when the biological information measuring device is alone, and the user can check the guidance display while operating the device alone. However, it is possible to measure biological information. The second height guide image, the second electrode contact guide image, the second measurement image, and the second measurement result image are the first height guide image, the first electrode contact guide image, and the first measurement result image, respectively. It may be the same image as the measurement-in-progress image and the first measurement result image, or it may be another image showing the same guidance content.

Furthermore, the operation to start measuring blood pressure of the human body may be performed on the other electronic device, and the input means may accept the operation via the communication means. With such a configuration, while the biometric information measuring device and other electronic devices are communicating with each other, the biometric information measuring device can be operated via the electronic device, increasing convenience. Can be done.

Further, the present invention can be understood as the following biological information processing system. That is,

FIG. 1 is a functional block diagram schematically showing a configuration example of a biological information processing system 1 according to the present embodiment. The biological information processing system 1 includes a wristwatch-type biological information measuring device 10 and a smartphone 20 as an example of an information processing device, and these devices are configured to be communicatively connectable.

(biological information measuring device)
FIG. 2A is a schematic diagram showing the external configuration of the biological information measuring device 10 according to this embodiment. FIG. 2B is an explanatory diagram showing a state when the biological information measuring device 10 according to the present embodiment is attached to the wrist T.

As shown in FIGS. 2A and 2B, the biological information measuring device 10 is roughly a wristwatch-type wearable device having a main body 11 and a belt 15, and measures blood pressure and heart rate when worn on the wrist T of a human body. Radio waveforms can be measured.

134a and 134b functions as a measurement start button for starting blood pressure measurement. Further, the acceleration sensor 131 corresponds to a position detection means according to the present invention, and detects the position and orientation of the biological information measuring device 10.

Further, as shown in FIG. 1, the main body section 11 includes a control section 100, an electrocardiographic signal measurement section 110, a blood pressure measurement section 120, a power supply section 132, a display section 133, an operation section 134, a communication section 135, It includes a storage section 136 and a vibration section 137. Each of these functional configurations will be described later.

The belt portion 15 also includes a cuff 121 for compressing an artery in the wrist T, a curler 152 for supporting the cuff 121, a first electrode 111, and a belt 151 for fixing the biological information measuring device 10 to the wrist T. We are prepared. For example, the belt 151 may be made up of a main band and a tip band, and may have a shape in which the tip band is fixed by a buckle on the parent band. Any configuration is acceptable as long as it can be fixed to . For example, it is also possible to adopt a configuration in which the device is fixed using a hook-and-loop fastener.

Next, the functional configuration of the main body section 11 will be explained. The control unit 100 controls the entire biological information measurement device 10 including the electrocardiographic signal measurement unit 110, the blood pressure measurement unit 120, and the like. The control unit 100 also includes functional units such as an electrode contact state determination unit 101, a blood pressure measurement posture determination unit 102, a batch measurement execution unit 103, and an information output processing unit 104. By reading and executing the information, a functional unit that controls each component of the biological information measuring device 10 and achieves these predetermined purposes is realized. Note that from a hardware perspective, the control unit 100 is configured to include a processor such as a CPU (Central Processing Unit).

The electrocardiographic signal measurement unit 110 includes a first electrode 111, a second electrode 112, and an electrocardiographic signal measurement circuit 113, and is configured to cover the surface of the human body (specifically, the wrist of one hand and the fingers of the other hand). The electrocardiographic signal of the user is measured based on the potential difference between the first electrode 111 and the second electrode 112 that are in contact with each other (so-called lead I). The electrocardiographic signal measurement circuit 113 also detects the contact state of the user's skin surface with the first electrode 111 and the second electrode 112. That is, the electrocardiographic signal measurement circuit 113 in this embodiment also serves as electrode contact state detection means according to the present invention. Note that the electrocardiographic signal measurement unit 110 also includes an AD conversion circuit, an amplifier, a filter, etc. (not shown), but since these are configured using known techniques, their explanation will be omitted.

The blood pressure measurement unit 120 includes a cuff 121, a pressure sensor 122, and a pump 123, and measures the user's blood pressure using a so-called oscillometric method. Blood pressure measurement using the oscillometric method is a well-known technique, so a detailed explanation will be omitted.

The power supply section 132 is configured to include a battery (not shown) that supplies power necessary for operating the device. The battery may be a secondary battery such as a lithium ion battery, or a primary battery.

The communication unit 135 includes an antenna for wireless communication (not shown), and performs information communication with other electronic devices such as the smartphone 20 by, for example, BLE (Bluetooth (registered trademark) Low Energy) communication. Note that a terminal for wired communication may be provided.

Further, in addition to the RAM, a long-term storage medium such as a flash memory may be provided. Also, measurement results such as electrocardiographic waveform data and measured blood pressure values are saved.

The vibrating section 137 includes a vibrator (not shown) made of a small motor or the like, and generates vibrations in a predetermined pattern set for each guidance content. Thereby, it is possible to notify the user of predetermined guidance information corresponding to the pattern.

Next, each functional unit included in the control unit 100 will be explained. The electrode contact state determination unit 101 determines whether the user is in stable contact with the first electrode 111 and the second electrode 112 based on the output of the electrocardiographic signal measurement circuit 113. Whether it is stable or not can be distinguished using any index, but the evaluation may also be performed using information such as baseline fluctuations in the electrocardiogram waveform and posture fluctuations of the device based on the output of the acceleration sensor 131. .

Based on the output of the acceleration sensor 131, the blood pressure measurement posture determination unit 102 determines whether the wrist of the user wearing the device is located at a height within a predetermined range, and more specifically determines the height of the heart. It is determined whether or not it is located at the same height as the grass. Further, it may also be determined whether the height is continuously maintained.

Based on the outputs of the electrode contact state determination unit 101 and the blood pressure measurement posture determination unit 102, the batch measurement execution unit 103 performs blood pressure measurement by the blood pressure measurement unit 120 and cardiac blood pressure measurement if both of these determination results are correct. Performs control to perform measurements of radio waveforms all at once. Note that the measurement of an electrocardiographic waveform here refers to recording the electrocardiographic signal measured by the electrocardiographic signal measurement unit 110 as waveform data. That is, in this embodiment, the electrocardiographic waveform measuring means includes the electrocardiographic signal measuring section 110 and the storage section 136.

The information output processing section 104 performs control to output guide information related to the use of the device by displaying an image on the display section 133 and using a vibration pattern on the vibrating section 137. Specifically, for example, control is executed to output information that guides the user in the posture for measuring biological information, information that guides the user to start and end the measurement, and the like. Examples of guide images displayed on the display unit 133 are shown in FIGS. 3A to 3D. Further, FIGS. 4A to 4D show examples of guide images displayed on the touch panel display 23 of the smartphone 20 while communication with the smartphone 20 is established.

FIGS. 3A and 4A are guide images that guide the user to lift and maintain the wrist on which the device is attached to the level of the heart in preparation for measurement. 3B and 4B are guide images that guide the user in touching the second electrode 112 of the device in preparation for measurement. FIGS. 3C and 4C are guide images showing that blood pressure (electrocardiogram) measurement is in progress. 3D and 4D are guide images showing the measurement results after the measurement is completed. These guide images can be stored in the storage unit 136, for example. Note that each image may be a still image or a moving image.

(information processing terminal)
Next, the smartphone 20, which is an example of an information processing terminal, will be described. As shown in FIG. 1, the smartphone 20 includes a control section 21, a communication section 22, a touch panel display 23, and a storage section 24. The control unit 21 is a means for controlling the smartphone 20, and includes, for example, a CPU, and executes various programs stored in the storage unit 24 to perform functions corresponding to these programs. The communication unit 22 includes an antenna for wireless communication, and has a function of communicating with other devices such as the biological information measuring device 10 and a wireless base station. Additionally, a terminal for wired communication may be provided.

The touch panel display 23 serves both as a display means as one of the output means and as an input means, and as described later, when a communication connection is established with the biological information measuring device 10, the touch panel display 23 serves as a display means as one of the output means and as an input means. Status information such as remaining time, electrocardiogram waveform graph data, etc. can be displayed. In addition, operations from the user are accepted via various input images.

The storage unit 24 includes a main storage device such as a RAM, and a long-term storage medium such as a flash memory, and stores various information such as application programs and measurement data.

(Processing of biological information measurement)
Next, the flow of processing when the biological information measuring device 10 measures biological information will be described based on FIG. 5. FIG. 5 is a flowchart illustrating the processing procedure when performing collective measurement of blood pressure and electrocardiogram waveforms using the biological information measuring device 10 according to the present embodiment.

First, the biological information measuring device 10 receives a blood pressure measurement start operation from the user via the operation unit 134 (S101). Then, the information output processing unit 104 outputs guide information that guides the wrist wearing the device to a height within a predetermined range (S102). Specifically, a guide image as shown in FIG. 3A is displayed on the display unit 133, or a predetermined pattern of vibration is caused to be generated by the vibration unit 137. Next, the blood pressure measurement posture determining unit 102 determines whether the height of the biological information measuring device 10 is within a predetermined range based on the output of the acceleration sensor 131 (S103). If it is determined that the height of the device is not within the predetermined range, the process returns to step S102 and the subsequent processes are repeated.

On the other hand, if it is determined in step S103 that the height of the device is within the predetermined range, the information output processing unit 104 touches the second electrode 112 in a posture suitable for measuring blood pressure and electrocardiographic waveforms. The guide information that guides the user is output (S104). Specifically, a guide image as shown in FIG. 3B is displayed on the display section 133, and a vibration section 137 is caused to oscillate in a predetermined pattern. Then, the electrode contact state determination unit 101 determines whether or not the user is stably touching the first electrode 111 and the second electrode 112 based on the output of the electrocardiographic signal measurement circuit 113 (S105 ). Here, if it is determined that the user is not in stable contact with each electrode, the process returns to step S104 and the subsequent processes are repeated.

On the other hand, if it is determined in step S105 that the user is in stable contact with each electrode, the batch measurement execution unit 103 performs the blood pressure measurement and the electrocardiogram waveform measurement by the blood pressure measurement unit 120 at the same time. Control is performed (S106). During the measurement of blood pressure and electrocardiographic waveforms, the information output processing unit 104 performs control to output guide information indicating that the measurement is being performed (S107). Specifically, a guide image as shown in FIG. 3C is displayed on the display section 133, and a vibration section 137 is caused to oscillate in a predetermined pattern. When the blood pressure measurement is finished, the electrocardiogram waveform measurement (that is, the recording of waveform data) is also finished at the same time, and the measurement results are stored in the storage unit 136 (S108). Then, the information output processing unit 104 displays a guide image (see FIG. 3D) showing the measurement results on the display unit 133, and this routine ends once.

(Cooperation with information processing terminal)
As described above, the biological information measuring device 10 can output guide information, measure blood pressure and electrocardiogram waveforms, and display measurement results by itself, but it can also be used by being communicatively connected to an information processing terminal. This can further improve convenience. Hereinafter, based on FIG. 6, a case will be described in which the biological information measuring device 10 is used in communication connection with the smartphone 20.

FIG. 6 is a diagram showing the flow of each process and the timing of information transmission between the devices when the biological information measuring device 10 and the smartphone 20 are linked via BLE communication to measure blood pressure and electrocardiogram waveforms. be. Note that the establishment of BLE communication is a known technique, so the explanation will be omitted, and here, the explanation will be given on the premise that the biological information measuring device 10 and the smartphone 20 have already been connected via BLE communication. Further, the same reference numerals are given to the above-mentioned processing flow of the biological information measuring device 10, and detailed description thereof will be omitted.

When the biological information measuring device 10 and the smartphone 20 are connected through BLE communication, when the biological information measuring device 10 receives an input of an operation to start blood pressure measurement (S101), the information output processing unit 104 determines whether the biological information measuring device 10 and the smartphone 20 are connected via BLE communication. A request is made to the smartphone 20 to output a guide image that guides the device to position the device at a height within a predetermined range (S201). The smartphone 20 that has received the request displays a guide image as shown in FIG. 4A on the touch panel display 23 (S301). Thereby, the user can prepare for measurement by viewing the guide image displayed on the highly visible touch panel display 23 of the smartphone 20.
