Description

Technical Field

[0001] This disclosure relates to terminal devices. Background Technology

[0002] Previously, blood pressure values ​​were repeatedly measured for health management. The measured blood pressure values ​​were used, for example, as a trend graph to confirm their changing trends. Japanese Patent Application Publication No. 10-286241 (Patent Document 1) discloses an automatic blood pressure measuring device configured to output a trend graph representing lifestyle-related information and blood pressure values ​​along a predetermined time axis.

[0005] Patent Document 1: Japanese Patent Application Publication No. 10-286241 Summary of the Invention

[0006] The problem that the invention aims to solve

[0007] Patent Document 1 investigated the correlation between changes in lifestyle-related information such as exercise volume and weight and blood pressure values ​​using the aforementioned configuration. Factors influencing blood pressure fluctuations included, for example, room temperature, external temperature, sleep, stress, and medication, in addition to the aforementioned weight and exercise volume. However, most of these factors affect long-term (e.g., monthly, yearly) blood pressure fluctuations rather than short-term (e.g., daily, weekly) fluctuations. Therefore, for example, displaying factors affecting both short-term and long-term blood pressure fluctuations (e.g., external temperature, weight) together could mislead the understanding of the correlation between blood pressure fluctuations and these factors.

[0008] One aspect of this disclosure is to provide a terminal device that can improve user convenience by presenting the correlation between blood pressure changes during a specified period and the factors that affect the blood pressure changes during that period.

[0009] Solution for solving the problem

[0010] In one example of this disclosure, the terminal device includes: a blood pressure information acquisition unit for acquiring blood pressure information of a subject measured by a blood pressure monitor; a factor information acquisition unit for acquiring multiple factor information that affects the blood pressure changes of the subject; an input unit for accepting input of a specified period unit from multiple period units; a selection unit for selecting a first factor information associated with the specified period unit from multiple factor information; and a display control unit for displaying the blood pressure information and the first factor information along a time axis on a display screen based on the specified period unit.

[0011] Based on the above structure, user convenience can be improved by presenting the correlation between blood pressure changes during a specified period and the factors that affect blood pressure changes during that period.

[0012] In other examples of this disclosure, the selection unit selects second factor information that is not associated with a specified period unit. The display control unit displays blood pressure information, first factor information, and second factor information along a time axis on the display screen based on the specified period unit. Blood pressure information and first factor information are displayed with priority over second factor information.

[0013] Based on the above structure, users can easily identify the primary factor information that should be focused on, and can also identify the secondary factor information as reference information.

[0014] In other examples of this disclosure, the display control unit displays the second factor information in gray, thereby prioritizing the display of blood pressure information and the first factor information over the second factor information.

[0015] Based on the above structure, users can clearly distinguish between the first factor information and the second factor information.

[0016] In other examples of this disclosure, the display control unit controls the display order of blood pressure information, first factor information, and second factor information, such that blood pressure information and first factor information are displayed in priority over second factor information, respectively.

[0017] Based on the above structure, users can clearly distinguish between the first factor information and the second factor information.

[0018] In other examples of this disclosure, multiple factors include room temperature and outside temperature during blood pressure measurement, the subject's weight, exercise information, sleep information, stress information, medication information, smoking information, and salt intake.

[0019] Based on the above structure, users can obtain specific examples of multiple factors that affect the blood pressure fluctuations of the person being measured.

[0020] In other examples of this disclosure, multiple period units include yearly units, monthly units, weekly units, and daily units. When the specified period unit is a yearly unit or a monthly unit, the selection unit selects at least one of external temperature, weight, exercise information, medication information, and salt intake as at least one first factor information.

[0021] Based on the above structure, users can grasp information on factors that are highly correlated with blood pressure changes over long-term periods.

[0022] In other examples of this disclosure, multiple period units include yearly units, monthly units, weekly units, and daily units. When the specified period unit is a weekly unit or a daily unit, the selection department selects at least one of room temperature, sleep information, stress information, medication information, and smoking information as at least one first factor information.

[0023] Based on the above structure, users can grasp information on factors that are highly correlated with blood pressure changes over short-term periods.

[0024] Invention Effects

[0025] According to this disclosure, user convenience can be improved by presenting the correlation between blood pressure changes during a specified period and the factors that affect blood pressure changes during that period. Attached Figure Description

[0037] Hereinafter, this embodiment will be described with reference to the accompanying drawings. In the following description, the same reference numerals are used to refer to the same parts. Their names and functions are also the same. Therefore, they will not be described in detail again.

[0038] [Application Example]

[0039] Application examples of the present invention will be described. Figure 1 This is a diagram illustrating the information processing system 1000 according to this embodiment.

[0040] Reference Figure 1 The information processing system 1000 includes a blood pressure monitor 100 for measuring the blood pressure of a subject and a terminal device 200 configured to communicate with the blood pressure monitor 100. Specifically, the blood pressure monitor 100 is an upper arm blood pressure monitor for measuring the blood pressure of a user, who is the subject of the measurement. The blood pressure monitor 100 has a main body and a cuff (arm cuff) as its main components. The blood pressure monitor 100 may also be a wrist blood pressure monitor in which the main body and the cuff (arm cuff) are integrated. Hereinafter, for ease of explanation, the subject of the blood pressure monitor 100 (user) will be referred to as the user of the terminal device 200.

[0041] exist Figure 1 In this scenario, we assume a user is using a blood pressure monitor 100 to measure their own blood pressure. When a blood pressure measurement instruction is received, the blood pressure monitor 100 begins measuring blood pressure (corresponding to...). Figure 1 (1) For example, the blood pressure monitor 100 extracts a pulse wave signal (variable component) superimposed on the cuff pressure, which represents the internal pressure of the cuff worn on the user's measurement site (e.g., arm), and calculates the blood pressure value based on the pulse wave signal using an oscillometric method. The blood pressure monitor 100 stores blood pressure information, such as the blood pressure value, in its internal memory. The blood pressure information includes the date and time of blood pressure measurement, systolic blood pressure (maximum blood pressure), diastolic blood pressure (minimum blood pressure), etc. The blood pressure information may also be stored in association with the user's identification information (e.g., user ID).

[0042] Terminal device 200 acquires (receives) user blood pressure information sent from blood pressure monitor 100, and stores the blood pressure information in its internal memory (corresponding to...). Figure 1 (2)). The terminal device 200 starts a management application for managing biological information such as blood pressure, obtains information on factors that affect changes in blood pressure, and stores it in the internal memory (corresponding to Figure 1(3)). Factor information includes, for example, the room temperature during blood pressure measurement, the outdoor temperature (external temperature), the user's weight, exercise information, sleep information, stress information, medication information, smoking information, and salt intake. The methods for obtaining each factor information will be described later. Factor information is associated with the date and time information such as the measurement date and time and the acquisition date and time.

[0043] Terminal device 200 receives a specified input (corresponding to) the unit of time (hereinafter also referred to as "period unit") for the period during which the user accepts and displays blood pressure values, etc. Figure 1 (4)). Period units include daily units, weekly units, monthly units, and yearly units. Specifically, a "daily unit" is a period unit based on one day, a "weekly unit" is a period unit based on one week, a "monthly unit" is a period unit based on one month, and a "yearly unit" is a period unit based on one year. Here, the specified period unit (hereinafter also referred to as the "specified period unit") is set to "weekly unit".

[0044] Terminal device 200 selects from multiple factor information stored in internal memory one or more factor information that has been associated with a specified period unit (here, "weekly unit") Figure 1 (5)). For example, “weekly units” were associated with room temperature, stress information, sleep information and medication information.

[0045] Terminal device 200 displays blood pressure information and selected factor information along a time axis on the display screen based on a specified period unit (corresponding to...). Figure 1 (6)). In Figure 1 In the example, weekly blood pressure values ​​and information on multiple factors (room temperature, stress, sleep, and medication) are displayed side-by-side along the timeline.

[0046] Based on the above application example, the terminal device 200 selects factor information suitable for a period unit specified by the user and displays this factor information together with blood pressure information in a time series. Therefore, the user can simultaneously confirm their own blood pressure fluctuations and factor information that is highly likely to affect those fluctuations, thus clearly identifying the correlation between blood pressure fluctuations and factor information.

[0047] Furthermore, by simply specifying the desired period, the system automatically displays information on factors highly correlated with blood pressure changes during that period, allowing users to easily and appropriately manage their blood pressure. Moreover, it does not display information on factors with low correlation to blood pressure changes during that period, thus avoiding user misunderstanding.

[0048] [Example of composition]

[0049] <Hardware Configuration>

[0050] Figure 2 This is a block diagram illustrating an example of the hardware configuration of a blood pressure monitor 100. (See reference...) Figure 2 The blood pressure monitor 100 includes a main body 10 and a cuff 20 as its main components. A fluid bag 22 is enclosed within the cuff 20. The main body 10 includes a processor 110, an air system assembly 30 for blood pressure measurement, an A / D (Analog / Digital) conversion circuit 310, a pump drive circuit 320, a valve drive circuit 330, a display 50, a memory 51, an operation unit 52, a communication interface 53, a temperature sensor 54, and a power supply unit 55.

[0051] The processor 110 is an arithmetic processing unit such as a CPU (Central Processing Unit) or MPU (MultiProcessing Unit). The processor 110 performs the various processes (steps) of the blood pressure monitor 100 described later by reading and executing the program stored in the memory 51. For example, the processor 110 controls the pump 32 and valve 33 to drive according to the operation signal from the operation unit 52. Furthermore, the processor 110 calculates the blood pressure value using an algorithm for blood pressure calculation using oscillometric methods and displays the blood pressure value on the display 50.

[0052] The memory 51 is implemented using RAM (Random Access Memory), ROM (Read-Only Memory), flash memory, etc. The memory 51 stores the program used to control the blood pressure monitor 100, the data used to control the blood pressure monitor 100, the setting data for setting various functions of the blood pressure monitor 100, and the data of blood pressure measurement results, pulse, pulse wave signals, etc. The memory 51 is also used as working memory when executing the program.

[0053] The air system assembly 30 supplies air to or discharges air from the fluid bag 22 enclosed in the cuff 20 via air piping. The air system assembly 30 includes: a pressure sensor 31 for detecting the pressure inside the fluid bag 22; and a pump 32 and a valve 33 as an expansion and contraction mechanism for expanding and contracting the fluid bag 22.

[0054] Pressure sensor 31 detects the pressure inside the fluid bag 22 (cuff pressure) and outputs a signal corresponding to the detected pressure (cuff pressure signal) to A / D conversion circuit 310. Pressure sensor 31 is, for example, a piezoresistive pressure sensor, connected via an air pipe to pump 32, valve 33, and the fluid bag 22 enclosed in the cuff 20. To pressurize the cuff, pump 32 supplies air, which serves as the fluid, to the fluid bag 22 via the air pipe. To control the cuff pressure, valve 33 opens / closes to expel air from the fluid bag 22 or seal air into the fluid bag 22 via the air pipe.

[0055] The A / D conversion circuit 310 converts the output value of the pressure sensor 31 (e.g., a voltage value corresponding to the change in resistance caused by the piezoresistive effect) from an analog signal to a digital signal and outputs it to the processor 110. The processor 110 acquires a signal representing the cuff pressure based on the output value of the A / D conversion circuit 310. The pump drive circuit 320 controls the drive of the pump 32 based on the control signal given by the processor 110. The valve drive circuit 330 controls the opening / closing of the valve 33 based on the control signal given by the processor 110.

[0056] The display 50 displays various information, including blood pressure measurement results, based on control signals from the processor 110. This information includes the current date and time, systolic blood pressure, diastolic blood pressure, pulse, room temperature, etc. The operation unit 52 inputs operation signals corresponding to instructions from the subject to the processor 110. For example, the operation unit 52 includes a measurement switch for receiving blood pressure measurement instructions. The communication interface 53 exchanges various information with external devices (e.g., terminal device 200). Communication methods include wireless communication such as BLE (Bluetooth Low Energy) or LAN (Local Area Network). The temperature sensor 54 measures the ambient temperature (room temperature). The power supply unit 55 supplies power to the processor 110 and all hardware components.

[0057] Figure 3 This is a block diagram illustrating an example of the hardware configuration of the terminal device 200. (See reference...) Figure 3 The terminal device 200 includes a processor 202, a memory 204, an input device 206, a display 208, and a communication interface 210 as its main components.

[0058] The processor 202 implements the various processing steps of the terminal device 200 (described later) by reading and executing the program stored in the memory 204. The memory 204 is implemented using RAM, ROM, flash memory, etc. The input device 206 accepts operation input for the terminal device 200. Typically, the input device 206 is implemented using buttons, a touch panel provided on the display 208, etc. The communication interface 210 is a communication interface used to exchange various data between the terminal device 200 and the blood pressure monitor 100.

[0059] <Functional Composition>

[0060] Figure 4 This is a block diagram illustrating an example of the functional configuration of the terminal device 200. (See reference...) Figure 4 The terminal device 200 includes a blood pressure information acquisition unit 250, a factor information acquisition unit 260, a period input unit 270, a selection unit 280, and a display control unit 290 as its main functional components. These functions are implemented, for example, by having the processor 202 of the terminal device 200 execute a program stored in the memory 204. It should be noted that some or all of these functions can also be implemented in hardware.

[0061] The blood pressure information acquisition unit 250 acquires (receives) the blood pressure information of the subject (user) measured by the blood pressure monitor 100. The blood pressure information acquisition unit 250 requests blood pressure information from the blood pressure monitor 100, thereby receiving the blood pressure information sent from the blood pressure monitor 100. Alternatively, the blood pressure information acquisition unit 250 determines the timing for the blood pressure monitor 100 to send the information, and receives the blood pressure information sent from the blood pressure monitor 100 at the time specified in the timeframe.

[0062] The factor information acquisition unit 260 acquires information on multiple factors that affect the blood pressure fluctuations of the subject. These factors include room temperature and outside temperature at the time of blood pressure measurement, the subject's weight, exercise information, sleep information, stress information, medication information, smoking information, and salt intake. Examples of how each factor's information is acquired are explained.

[0063] The factor information acquisition unit 260 acquires (receives) the room temperature and the date and time of measurement measured by the sphygmomanometer 100. The factor information acquisition unit 260 periodically acquires (receives) the external temperature from a server that provides meteorological information. Typically, the acquired external temperature is the external temperature of the area where the person being measured resides.

[0064] The factor information acquisition unit 260 acquires (receives) the weight of the person being measured from a communication-enabled weighing scale. The weighing scale's measurement data includes the weight (measured value) and the date and time of measurement. The factor information acquisition unit 260 may also acquire (receive) the number of steps measured by a prescribed pedometer as exercise information. The pedometer's measurement data includes the number of steps (measured value) and the date and time of measurement. The factor information acquisition unit 260 may also acquire the number of steps measured by a pedometer application installed on the terminal device 200 as exercise information.

[0065] The factor information acquisition unit 260 acquires (receives) sleep-related information (sleep information) measured by a prescribed sleep measurement device. The sleep measurement device may be a wearable device worn on the user's body, such as a watch, ring, or eye mask. The sleep information includes evaluation results of the user's sleep quality (e.g., "good," "poor," etc.) and the date and time of measurement. It should be noted that the factor information acquisition unit 260 may also acquire sleep information measured by a sleep measurement application installed on the terminal device 200.

[0066] The factor information acquisition unit 260 accepts input from the user regarding stress, medication, and smoking information via the input device 206. Medication information includes whether medication was taken and the date and time of administration. Stress information includes whether stress was present and the date and time the information was received. Smoking information includes whether smoking was present and the date and time of smoking.

[0067] The factor information acquisition unit 260 accepts the input of the salt intake by the user via the input device 206. This salt intake is measured by a prescribed salt meter. Alternatively, the factor information acquisition unit 260 can also acquire the salt intake calculated by a known diet management application installed on the terminal device 200. The diet management application analyzes the dietary information input by the user to calculate the salt intake. Based on the acquired salt intake, the factor information acquisition unit 260 calculates the user's daily salt intake.

[0068] The factor information acquisition unit 260 only needs to acquire the information of each of the above factors, and the acquisition method is not limited to the above acquisition method.

[0069] The period input unit 270 receives input from a specified period unit specified by the user via the input device 206. Specifically, the user uses the input device 206 to specify a desired period unit (e.g., a week) from among multiple period units (e.g., a day unit, a week unit, a month unit, and a year unit).

[0070] The selection unit 280 selects factor information X that is associated with a specified period unit from multiple factor information. When the specified period unit is a year or a month, the selection unit 280 selects external temperature, weight, exercise information, medication information, and salt intake as multiple factor information X. It should be noted that the selection unit 280 may also select at least one factor information X (i.e., at least one of external temperature, weight, exercise information, medication information, and salt intake).

[0071] Furthermore, when the specified period is in weekly or daily units, the selection unit 280 selects room temperature, sleep information, stress information, medication information, and smoking information as multiple factor information X. It should be noted that the selection unit 280 may also select at least one factor information X (i.e., at least one of room temperature, sleep information, stress information, medication information, and smoking information).

[0072] Information on factors believed to influence long-term blood pressure variability is correlated with long-term time units (e.g., years, months), while information on factors believed to influence short-term blood pressure variability is correlated with short-term time units (e.g., weeks, days). The time units correlated with each factor are explained in detail below.

[0073] In cold weather, such as winter, blood vessels constrict and blood pressure tends to rise; conversely, in hot weather, such as summer, blood vessels dilate and blood pressure tends to fall. Generally, blood pressure measurements are taken indoors, so it's difficult to assume that external temperature immediately affects blood pressure. Therefore, it's necessary to establish a correlation between external temperature and long-term time units.

[0074] It is known that weight gain leads to higher blood pressure, and weight loss leads to lower blood pressure. Generally, weight does not change drastically, but rather gradually over a long period. Therefore, weight is correlated with long-term time units.

[0075] It is known that sustained aerobic exercise (e.g., walking) lowers blood pressure. Therefore, exercise information (e.g., step count) is correlated with long-term time units.

[0076] It is known that increased salt intake leads to higher blood pressure, while decreased salt intake leads to lower blood pressure. For example, in the treatment of hypertension, measures such as limiting daily salt intake are implemented. Generally speaking, by consistently restricting salt intake over a long period, a decrease in blood pressure can be expected. Therefore, a relationship is established between salt intake and long-term timeframes.

[0077] Generally, blood pressure measurements are taken in a room, so the temperature of the room (i.e., room temperature) immediately affects blood pressure. Therefore, room temperature is correlated with short-term time units.

[0078] It is known that short sleep duration and poor sleep quality activate the sympathetic nervous system, leading to elevated blood pressure. Therefore, sleep information is associated with short-term time units. Blood pressure can sometimes rise sharply due to physical or mental stress. Therefore, stress information is associated with short-term time units. It is known that smoking causes vasoconstriction, thus raising blood pressure. Therefore, smoking information is associated with short-term time units.

[0079] To treat hypertension, people consider taking antihypertensive medication to lower their blood pressure. Typically, antihypertensive medications are prescribed to gradually lower blood pressure rather than rapidly. Therefore, medication information is correlated with long-term timeframes. On the other hand, as users, we sometimes also want to know how our blood pressure changes on days we take antihypertensive medication versus days we don't. Therefore, medication information is also correlated with short-term timeframes.

[0080] The display control unit 290 displays blood pressure information and factor information X along a time axis on the display screen based on a specified period unit. For example, when the specified period unit is a week, the display control unit 290 displays blood pressure information and factor information X (e.g., room temperature, sleep information, stress information, medication information, and smoking information) selected by the selection unit 280 along the time axis on the display screen.

[0081] In other aspects, the selection unit 280 selects factor information Y that is not associated with the specified period unit. The display control unit 290 displays the blood pressure information, factor information X, and factor information Y along the time axis on the display screen based on the specified period unit. In this case, the blood pressure information and factor information X are displayed with priority over factor information Y.

[0082] Specifically, the display control unit 290 displays factor information Y in grayscale, thereby prioritizing the display of blood pressure information and factor information X over factor information Y. Furthermore, the display control unit 290 controls the display order of blood pressure information, factor information X, and factor information Y, ensuring that blood pressure information and factor information X are displayed before factor information Y. Specific display examples executed by the display control unit 290 will be described later.

[0083] <Example Display>

[0084] Figure 5 This is a diagram showing an example of the display screen of the terminal device 200. (See reference...) Figure 5Display screen 510 is an example of a screen displayed on monitor 208 when the specified period is in daily units. In display screen 510, blood pressure information and factor information X (in this case, room temperature, stress, sleep, and medication information) associated with the daily unit are displayed in a time sequence. Specifically, blood pressure information and factor information X for one day (twenty-four hours) are displayed side-by-side along a time axis (e.g., hourly).

[0085] Display screen 510 includes a bar graph representing blood pressure values, a line graph representing the room temperature at the time of blood pressure measurement, a graph showing whether or not there was pressure, a graph showing sleep quality (good, poor), and a graph showing whether or not medication was taken. The upper and lower ends of the bar graph representing blood pressure values ​​show systolic blood pressure and diastolic blood pressure, respectively.

[0086] According to display screen 510, there was no stress and sleep was good around 8 AM. It suggests a possible rise in blood pressure due to stress around 11 AM. Additionally, it shows that medication was taken around 12 PM.

[0087] Figure 6 These are diagrams illustrating other examples of the display screen of the terminal device 200. (See also...) Figure 6 Display screen 520 is an example of a screen displayed on monitor 208 when the specified period is in weekly units. Display screen 520 displays blood pressure information for one week and factor information X (in this case, room temperature, stress, sleep, and medication information) associated with the weekly unit, arranged in a time sequence. Specifically, the blood pressure information for one week (seven days) and factor information X are displayed side-by-side along a time axis (e.g., by each day).

[0088] The same factor information X is associated with daily and weekly units, therefore the content displayed on display screen 520 is similar to that displayed on display screen 510. The blood pressure value for a specific day (e.g., the 8th) shows the average blood pressure measured on the 8th. The upper and lower ends of the bar chart show the average systolic and diastolic blood pressure for the day, respectively. Room temperature shows the average room temperature at the time of the blood pressure measurement. Stress information indicates whether there was stress throughout the day. Sleep information shows the sleep quality for the day (good, poor). Medication information indicates whether any medication was taken on the day.

[0089] According to display screen 520, the blood pressure was higher on the 9th due to lack of sleep, higher on the 11th due to a decrease in room temperature, and higher on the 13th due to stress.

[0090] Figure 7 This is another example of a display screen on terminal device 200. (See also...) Figure 7Display screen 530 is an example of a screen displayed on monitor 208 when the specified period is in years. Display screen 530 displays blood pressure information for one year and factor information X (in this case, temperature, weight, medication information, and salt intake) linked to the year in a time sequence. Specifically, blood pressure information and factor information X for one year (twelve months) are displayed side-by-side along a time axis (e.g., by each month).

[0091] Display screen 530 includes a bar chart showing the average blood pressure over a month, a line graph showing the average temperature (outdoor temperature) over a month, a line graph showing the average weight over a month, a chart showing whether or not the subject was taking medication over a month, and a chart showing the average salt intake over a month. The upper and lower ends of the bar charts show the average systolic and diastolic blood pressure over a month, respectively. The higher the average salt intake, the more concentrated the salt intake data is displayed.

[0092] According to screen 530, the blood pressure fluctuates with changes in external temperature, and through weight loss, medication, and salt reduction, the blood pressure is trending downward.

[0093] It should be noted that the same applies to the display screen on monitor 208 when the specified period is in monthly units. In this display screen, the blood pressure information for one month and the factor information X associated with the monthly unit are displayed side by side along the time axis (e.g., by each week).

[0094] In the above Figure 5 The display screen 510 and Figure 6 In display screen 520, only factor information X (e.g., room temperature, stress information, sleep information, and medication information) associated with short-term time units is displayed, while factor information Y not associated with that time unit is not displayed. Similarly, in Figure 7 In the display screen 530, only factor information X (e.g., external temperature, weight, medication information, and salt intake) that is associated with the long-term period unit is displayed, and factor information Y that is not associated with the period unit is not displayed.

[0095] However, it is also possible, as described below, that the terminal device 200 adopts a display method in which factor information X is displayed before factor information Y.

[0096] Figure 8 This is a diagram illustrating an example of how factor information is prioritized. (See reference...) Figure 8 Display screen 540 is a screen displayed on monitor 208 during a specified period in weeks. In display screen 540, besides displaying... Figure 6In addition to the blood pressure information and factor information X (in this case, room temperature, pressure, sleep information, and medication information) displayed in the weekly unit display screen 520, factor information Y (in this case, outside temperature, weight, and salt intake) is also displayed.

[0097] Here, blood pressure information and factor information X are displayed at the top of the screen, while factor information Y is displayed at the bottom. Specifically, the processor 202 (display control unit 290) controls the display order so that blood pressure information and factor information X are displayed before factor information Y, respectively.

[0098] Figure 9 This is a diagram illustrating other examples of how factor information is prioritized. (See also...) Figure 9 Display screen 550 is a screen displayed on monitor 208 during a specified period in weeks. Display screen 550 displays [the following information / content]. Figure 8 The same items (i.e., blood pressure information, factor information X, and factor information Y).

[0099] However, factor information Y is displayed in grayscale, making it more difficult to visually confirm than blood pressure information and factor information X. Therefore, processor 202 (display control unit 290) displays factor information Y in grayscale, thereby prioritizing the display of blood pressure information and factor information X over factor information Y.

[0100] Based on display screens 540 and 550, factor information X, which is highly correlated with the specified period unit, is displayed in priority over factor information Y, which is less correlated. Therefore, users can easily identify factor information X that should be of interest and can also use factor information Y as reference information.

[0101] <Processing Procedure>

[0102] Figure 10 This is a flowchart illustrating an example of the processing procedure of the blood pressure monitor 100. Here, it is assumed that a blood pressure measurement based on decompression is performed, but a blood pressure measurement can also be performed using a pressurization method.

[0103] Reference Figure 10 The processor 110 of the blood pressure monitor 100 initializes the pressure sensor 31 (step S10). Specifically, the processor 110 initializes the processing memory area and, with the pump 32 disconnected (stopped) and the valve 33 open, adjusts the pressure sensor 31 to 0 mmHg (sets the atmospheric pressure to 0 mmHg).

[0104] The processor 110 closes the valve 33 via the valve drive circuit 330 (step S12), drives the pump 32 via the pump drive circuit 320, and begins pressurizing the cuff 20 (fluid bag 22) (step S14). At this time, the processor 110 supplies air from the pump 32 to the fluid bag 22 through the air pipe, and controls the pressurization rate of the cuff pressure, which is the pressure inside the fluid bag 22, based on the output of the pressure sensor 31.

[0105] Processor 110 determines whether the cuff pressure has reached or exceeded a threshold P (step S16). Typically, the threshold P is set to a value that is 30 mmHg to 40 mmHg higher than the expected maximum blood pressure (systolic blood pressure).

[0106] If the cuff pressure is less than the threshold P (No in step S16), the processor 110 returns to step S14. If the cuff pressure is greater than the threshold P (Yes in step S16), the processor 110 stops the pump 32 (step S18) and controls the valve 33 to gradually open (step S20). Thus, the pressurization process changes to the depressurization process, and the cuff pressure is gradually reduced.

[0107] During the decompression process, the processor 110 extracts the pulse wave signal from the cuff pressure signal detected by the pressure sensor 31, and attempts to calculate the systolic and diastolic blood pressure based on the pulse wave signal, determining whether the blood pressure calculation is complete (step S22). If the blood pressure calculation is incomplete (no in step S22), the processor 110 repeatedly performs steps S20 and S22. If the blood pressure calculation is complete (yes in step S22), the processor 110 performs the following control: fully opens the valve 33 (step S24), rapidly venting the air from the cuff 20.

[0108] The processor 110 measures the room temperature via the temperature sensor 54 (step S26) and displays the blood pressure value measured by the blood pressure monitor on the display 50 (step S28). The processor 110 sends the blood pressure information and room temperature data to the terminal device 200 via the communication interface 53 (step S30). It should be noted that the blood pressure information and room temperature data are stored in the memory 51 of the blood pressure monitor 100.

[0109] Figure 11 This is a diagram illustrating an example of the processing procedure of the terminal device 200. (Refer to...) Figure 11The processor 202 of the terminal device 200 receives blood pressure information and room temperature data via the communication interface 210 (step S50). The processor 202 stores this data in the memory 204 (step S52). The processor 202 accepts the startup input of the management application via the input device 206 and starts the management application (step S54). The processor 202 acquires various factor information through the acquisition method described above (step S56).

[0110] Processor 202 accepts a specified input period unit via input device 206 (step S58). Based on the specified period unit, processor 202 displays blood pressure and factor information along a timeline on display 208 (step S60). For example, processor 202 displays display screens 510-550 on display 208. Processor 202 determines whether an end instruction for the management application has been accepted via input device 206 (step S62). If the end instruction is not accepted (no in step S62), processor 202 returns to step S58. If the end instruction is accepted (yes in step S62), processor 202 terminates processing. For example, processor 202 switches to background operations, executing steps S50, S52, etc.
