Description

terminal device

[0001] The present disclosure relates to a terminal device.

[0002] Conventionally, repeated measurement of blood pressure values ​​has been desirable for health management. Measured blood pressure values ​​are used, for example, as a blood pressure trend graph to confirm the trend of changes. The automatic blood pressure measuring device disclosed in Japanese Patent Laid-Open Publication No. 10-286241 (Patent Document 1) is configured to output a trend graph that represents lifestyle-related information and blood pressure values ​​along a predetermined time axis.

[0003] Japanese Patent Application Publication No. 10-286241

[0004] Patent Document 1 considers using the above configuration to recognize the relationship between changes in lifestyle-related information, such as the amount of exercise and body weight, and blood pressure values. Factors that affect blood pressure fluctuations include, for example, body weight, the amount of exercise, and various other factors, such as room temperature, outdoor temperature, sleep, stress, and medication. However, not all of these factors affect short-term (e.g., one day, one week) blood pressure fluctuations; many factors affect long-term (e.g., one month, one year) blood pressure fluctuations. Therefore, for example, if short-term blood pressure fluctuations and factors that affect long-term blood pressure fluctuations (e.g., outdoor temperature, body weight) are displayed together, the relationship between blood pressure fluctuations and these factors may be misunderstood.

[0005] An object of one aspect of the present disclosure is to provide a terminal device that can improve user convenience by presenting the relationship between blood pressure fluctuations over a specified period and factors that affect blood pressure fluctuations over that period.

[0006] In one example of the present disclosure, a terminal device includes a blood pressure information acquisition unit that acquires blood pressure information of a subject measured by a sphygmomanometer, an element information acquisition unit that acquires multiple pieces of element information that affect blood pressure fluctuations of the subject, an input unit that accepts input of a specified period unit that is designated from multiple period units, a selection unit that selects first element information associated with the specified period unit from the multiple piece of element information, and a display control unit that displays the blood pressure information and the first element information on a display screen along a time axis based on the designated period unit.

[0007] According to the above configuration, the user's convenience can be improved by presenting the correlation between blood pressure fluctuations during a specified period and factors that affect blood pressure fluctuations during that period.

[0008] In another example of the present disclosure, the selection unit selects second element information that is not associated with the specified time unit. The display control unit displays the blood pressure information, the first element information, and the second element information on the display screen along a time axis based on the specified time unit. The blood pressure information and the first element information are each displayed with priority over the second element information.

[0009] According to the above configuration, the user can easily check the first element information that requires attention, and can also check the second element information as reference information.

[0010] In another example of the present disclosure, the display control unit displays the second element information in a grayed-out state, thereby displaying each of the blood pressure information and the first element information in priority over the second element information.

[0011] According to the above configuration, the user can clearly distinguish between the first element information and the second element information.

[0012] In another example of the present disclosure, the display control unit controls the display order of the blood pressure information, the first element information, and the second element information so that each of the blood pressure information and the first element information is displayed with priority over the second element information.

[0013] According to the above configuration, the user can clearly distinguish between the first element information and the second element information.

[0014] In another example of the present disclosure, the plurality of element information includes the 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.

[0015] According to the above configuration, the user can grasp specific examples of a plurality of pieces of element information that affect the blood pressure fluctuation of the measurement subject.

[0016] In another example of the present disclosure, the plurality of time periods include years, months, weeks, and days. When the specified time period is years or months, the selection unit selects at least one of an outside temperature, a weight, exercise information, medication information, and a salt intake amount as the at least one first element information.

[0017] According to the above configuration, the user can grasp element information that is highly relevant to blood pressure fluctuations over a long period of time.

[0018] In another example of the present disclosure, the plurality of time periods include a year, a month, a week, and a day. When the specified time period is a week or a day, the selection unit selects at least one of room temperature, sleep information, stress information, medication information, and smoking information as the at least one first element information.

[0019] According to the above configuration, the user can grasp element information that is highly relevant to blood pressure fluctuations over short-term periods.

[0020] According to the present disclosure, convenience for users can be improved by presenting the correlation between blood pressure fluctuations during a specified period and factors that affect blood pressure fluctuations during that period.

[0022] Hereinafter, the present embodiment will be described with reference to the drawings. In the following description, the same components are denoted by the same reference numerals. The names and functions of these components are also the same. Therefore, detailed description thereof will not be repeated.

[0023] [Application Example] An application example of the present invention will be described below. Fig. 1 is a diagram showing an information processing system 1000 according to the present embodiment.

[0024] Referring to FIG. 1 , the information processing system 1000 includes a sphygmomanometer 100 that measures the blood pressure of a person being measured and a terminal device 200 that is configured to be able to communicate with the sphygmomanometer 100. Specifically, the sphygmomanometer 100 is an upper arm sphygmomanometer that measures the blood pressure of a user being measured. The sphygmomanometer 100 has a main body and a cuff (arm band) as its main components. The sphygmomanometer 100 may also be a wrist-type sphygmomanometer in which the main body and the cuff (arm band) are integrated. Hereinafter, for ease of explanation, the person being measured (user) of the sphygmomanometer 100 is assumed to be the user of the terminal device 200.

[0025] FIG. 1 illustrates a scenario in which a user measures their own blood pressure using a blood pressure monitor 100. Upon receiving a blood pressure measurement instruction, the blood pressure monitor 100 starts blood pressure measurement (corresponding to (1) in FIG. 1). For example, the blood pressure monitor 100 extracts a pulse wave signal (fluctuation component) superimposed on a cuff pressure indicating the internal pressure of a cuff attached to the user's measurement site (e.g., arm), and calculates a blood pressure value using an oscillometric method based on the pulse wave signal. The blood pressure monitor 100 stores blood pressure information such as blood pressure values ​​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 be stored in association with the user's identification information (e.g., user ID).

[0026] The terminal device 200 acquires (receives) the user's blood pressure information transmitted from the sphygmomanometer 100 and stores the blood pressure information in its internal memory (corresponding to (2) in FIG. 1). The terminal device 200 launches a management application that manages biological information such as blood pressure, acquires element information that affects blood pressure fluctuations, and stores the information in its internal memory (corresponding to (3) in FIG. 1). The element information includes, for example, the room temperature at the time of blood pressure measurement, the outdoor temperature (outdoor temperature), the user's weight, exercise information, sleep information, stress information, medication information, smoking information, and salt intake. The method for acquiring each element information will be described later. The element information is associated with date and time information such as the measurement date and time and acquisition date and time of the element information.

[0027] The terminal device 200 accepts from the user a designated input of the unit of time (hereinafter also referred to as "unit of time") for displaying blood pressure values, etc. (corresponding to (4) in Figure 1). The unit of time includes daily, weekly, monthly, and yearly. Specifically, "daily" refers to a unit of one day, "weekly" refers to a unit of one week, "monthly" refers to a unit of one month, and "yearly" refers to a unit of one year. Here, the designated unit of time (hereinafter also referred to as "designated unit of time") is assumed to be "weekly."

[0028] The terminal device 200 selects one or more pieces of element information associated with a specified time period (here, "weekly") from among the pieces of element information stored in the internal memory (corresponding to (5) in FIG. 1). For example, room temperature, stress information, sleep information, and medication information are associated with the "weekly" period.

[0029] The terminal device 200 displays the blood pressure information and the selected element information on the display screen along the time axis based on the specified time unit (corresponding to (6) in Fig. 1). In the example of Fig. 1, blood pressure values ​​for one week and multiple element information (room temperature, stress information, sleep information, medication information) are displayed in parallel along the time axis.

[0030] According to the above application example, the terminal device 200 selects element information appropriate for the time period specified by the user and displays the element information together with the blood pressure information in chronological order. This allows the user to simultaneously check their own blood pressure fluctuations and element information that is likely to affect the blood pressure fluctuations, thereby clearly recognizing the relationship between blood pressure fluctuations and element information.

[0031] In addition, the user can easily and appropriately manage their own blood pressure by simply specifying the desired time period, and the element information highly relevant to blood pressure fluctuations during that period is automatically displayed.Furthermore, the element information less relevant to blood pressure fluctuations during that period is not displayed, so the user will not be misled.

[0032] [Configuration Example] <Hardware Configuration> Fig. 2 is a block diagram showing an example of the hardware configuration of sphygmomanometer 100. Referring to Fig. 2, sphygmomanometer 100 includes, as main components, a main body 10 and a cuff 20. Cuff 20 contains a fluid bag 22. Main body 10 includes a processor 110, an air system component 30 for blood pressure measurement, an A / D 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.

[0033] The processor 110 is an arithmetic processing unit such as a CPU (Central Processing Unit) or an MPU (Multi Processing Unit). The processor 110 reads and executes programs stored in the memory 51 to realize each of the processes (steps) of the sphygmomanometer 100, which will be described later. For example, the processor 110 controls the driving of the pump 32 and the valve 33 in response to an operation signal from the operation unit 52. The processor 110 also calculates blood pressure values ​​using an algorithm for calculating blood pressure using the oscillometric method, and displays the calculated values ​​on the display 50.

[0034] The memory 51 is realized by a RAM (Random Access Memory), a ROM (Read-Only Memory), a flash memory, etc. The memory 51 stores a program for controlling the sphygmomanometer 100, data used to control the sphygmomanometer 100, setting data for setting various functions of the sphygmomanometer 100, data on blood pressure measurement results, pulse and pulse wave signals, etc. The memory 51 is also used as a work memory, etc. when the program is executed.

[0035] The air system component 30 supplies or exhausts air through an air pipe to or from the fluid bag 22 contained in the cuff 20. The air system component 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 inflation / deflation mechanism for inflating and deflating the fluid bag 22.

[0036] The pressure sensor 31 detects the pressure (cuff pressure) inside the fluid bag 22 and outputs a signal (cuff pressure signal) corresponding to the detected pressure to the A / D conversion circuit 310. The pressure sensor 31 is, for example, a piezo-resistive pressure sensor, and is connected to the pump 32, the valve 33, and the fluid bag 22 contained in the cuff 20 via air piping. The pump 32 supplies air as a fluid to the fluid bag 22 through the air piping to increase the cuff pressure. The valve 33 opens and closes to control the cuff pressure by discharging air from the fluid bag 22 through the air piping or by sealing air in the fluid bag 22.

[0037] The A / D conversion circuit 310 converts the output value of the pressure sensor 31 (e.g., a voltage value corresponding to a change in electrical resistance due to the piezo-resistance effect) from an analog signal to a digital signal and outputs the digital signal to the processor 110. The processor 110 acquires a signal representing the cuff pressure according to the output value of the A / D conversion circuit 310. The pump drive circuit 320 controls the drive of the pump 32 based on a control signal provided by the processor 110. The valve drive circuit 330 controls the opening and closing of the valve 33 based on a control signal provided by the processor 110.

[0038] The display 50 displays various information, including blood pressure measurement results, based on control signals from the processor 110. The various information includes the current date and time, systolic blood pressure, diastolic blood pressure, pulse, room temperature, etc. The operation unit 52 inputs operation signals to the processor 110 in response to instructions from the subject. For example, the operation unit 52 includes a measurement switch for accepting a blood pressure measurement instruction. The communication interface 53 exchanges various information with an external device (e.g., the terminal device 200). Examples of communication methods include wireless communication methods such as BLE (Bluetooth (registered trademark) low energy) and wireless 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 each piece of hardware.

[0039] Fig. 3 is a block diagram showing an example of a hardware configuration of the terminal device 200. Referring to Fig. 3, the terminal device 200 includes, as main components, a processor 202, a memory 204, an input device 206, a display 208, and a communication interface 210.

[0040] The processor 202 reads and executes programs stored in the memory 204 to implement each of the processes (steps) of the terminal device 200, which will be described later. The memory 204 is implemented by a RAM, a ROM, a flash memory, etc. The input device 206 accepts operational inputs to the terminal device 200. Typically, the input device 206 is implemented by buttons, a touch panel provided on the display 208, etc. The communication interface 210 is a communication interface for exchanging various data between the terminal device 200 and the sphygmomanometer 100.

[0041] <Functional Configuration> Fig. 4 is a block diagram showing an example of the functional configuration of the terminal device 200. Referring to Fig. 4, the terminal device 200 includes, as main functional components, a blood pressure information acquisition unit 250, an element information acquisition unit 260, a period input unit 270, a selection unit 280, and a display control unit 290. Each of these functions is realized, for example, by the processor 202 of the terminal device 200 executing a program stored in the memory 204. Note that some or all of these functions may be configured to be realized by hardware.

[0042] The blood pressure information acquiring unit 250 acquires (receives) blood pressure information of the person being measured (user) measured by the sphygmomanometer 100. The blood pressure information acquiring unit 250 receives blood pressure information transmitted from the sphygmomanometer 100 by requesting the blood pressure information from the sphygmomanometer 100. Alternatively, the blood pressure information acquiring unit 250 determines the timing for transmission by the sphygmomanometer 100 and receives the blood pressure information transmitted from the sphygmomanometer 100 when the timing is reached.

[0043] The element information acquisition unit 260 acquires a plurality of element information that affect the subject's blood pressure fluctuations. The plurality of element information includes the 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. An example of a method for acquiring each element information will be described below.

[0044] The element information acquisition unit 260 acquires (receives) the room temperature measured by the sphygmomanometer 100 and the date and time of measurement from the sphygmomanometer 100. The element information acquisition unit 260 periodically acquires (receives) the outside air temperature from a server that provides meteorological information. The acquired outside air temperature is typically the outside air temperature in the area where the person being measured resides.

[0045] The element information acquisition unit 260 acquires (receives) the weight of the person being measured from a weighing scale with a communication function that measured the weight. The measurement data from the weighing scale includes the weight (measured value) and the date and time of measurement. The element information acquisition unit 260 acquires (receives), for example, the number of steps measured by a specified pedometer as exercise information. The measurement data from the pedometer includes the number of steps (measured value) and the date and time of measurement. The element information acquisition unit 260 may also acquire, as exercise information, the number of steps measured by a step counting application installed on the terminal device 200.

[0046] The element information acquisition unit 260 acquires (receives) information related to sleep (sleep information) measured by a predetermined sleep measurement device. The sleep measurement device is a wearable device attached to the user's body, such as a wristwatch, a ring, or an eye mask. The sleep information includes an evaluation result of the user's sleep quality (e.g., "good," "poor," etc.) and the date and time of measurement. Note that the element information acquisition unit 260 may acquire sleep information measured by a sleep measurement application installed on the terminal device 200.

[0047] The element information acquisition unit 260 accepts input of the user's stress information, medication information, and smoking information via the input device 206. The medication information includes whether or not the user has taken medication and the date and time the medication was taken. The stress information includes whether or not the user has experienced stress and the date and time the input of the information was accepted. The smoking information includes whether or not the user smokes and the date and time the user smoked.

[0048] The element information acquisition unit 260 accepts input of the amount of salt ingested by the user via the input device 206. The amount of salt is the amount of salt in the user's diet measured using a predetermined salt meter. The element information acquisition unit 260 may also acquire the amount of salt calculated by a known dietary management application installed on the terminal device 200. The dietary management application calculates the amount of salt by analyzing the dietary details input by the user. The element information acquisition unit 260 calculates the user's daily salt intake based on the acquired amount of salt.

[0049] The element information acquisition unit 260 is only required to be able to acquire the above-mentioned element information, and the acquisition method is not limited to the above-mentioned acquisition method.

[0050] The period input unit 270 accepts an input of a specified period unit designated by the user via the input device 206. Specifically, the user uses the input device 206 to designate a desired period unit (e.g., week unit) from among a plurality of period units (e.g., day unit, week unit, month unit, year unit).

[0051] The selection unit 280 selects, from the plurality of pieces of element information, element information X associated with the designated unit of time. When the designated unit of time is yearly or monthly, the selection unit 280 selects outside temperature, weight, exercise information, medication information, and salt intake as the plurality of pieces of element information X. Note that the selection unit 280 may select at least one piece of element information X (i.e., at least one of outside temperature, weight, exercise information, medication information, and salt intake).

[0052] Furthermore, when the specified period unit is a week or a day, the selection unit 280 selects room temperature, sleep information, stress information, medication information, and smoking information as the plurality of element information X. Note that the selection unit 280 may select at least one element information X (i.e., at least one of room temperature, exercise information, sleep information, stress information, medication information, and smoking information).

[0053] Element information that is thought to affect long-term blood pressure fluctuations is associated with long-term time units (e.g., years or months), and element information that is thought to affect short-term blood pressure fluctuations is associated with short-term time units (e.g., weeks or days). The time units associated with each element information will be specifically described below.

[0054] When the outside temperature is low, such as in winter, blood vessels constrict and blood pressure tends to rise, while when the outside temperature is high, such as in summer, blood vessels expand and blood pressure tends to fall. Generally, blood pressure is measured indoors, so it is unlikely that the outside temperature will have an immediate effect on blood pressure. Therefore, the outside temperature is associated with a long-term time period.

[0055] It is known that weight gain leads to higher blood pressure, and weight loss leads to lower blood pressure. Generally, weight does not fluctuate suddenly, but rather gradually over the long term. Therefore, weight is associated with a long-term time period.

[0056] Continuous aerobic exercise (e.g., walking) is known to lower blood pressure, so exercise information (e.g., step count) is associated with long-term time units.

[0057] It is known that an increase in salt intake increases blood pressure, while a decrease in salt intake decreases blood pressure. For example, in the treatment of hypertension, measures such as limiting daily salt intake are taken. In general, blood pressure is expected to decrease by continuing to limit salt intake over the long term. Therefore, salt intake is related to a long-term unit of time.

[0058] Generally, blood pressure measurements are taken in a room, and the temperature of the room where blood pressure is measured (i.e., room temperature) immediately affects blood pressure, so room temperature is related to short-term time units.

[0059] It is known that when sleep time is short and sleep quality is poor, the sympathetic nervous system becomes activated and blood pressure rises. Therefore, sleep information is associated with short-term time units. Blood pressure can rise suddenly due to physical or mental stress. Therefore, stress information is associated with short-term time units. It is known that blood pressure rises after smoking because smoking has the effect of constricting blood vessels. Therefore, smoking information is associated with short-term time units.

[0060] To treat hypertension, antihypertensive drugs may be taken to lower blood pressure. Typically, antihypertensive drugs are prescribed to gradually lower blood pressure, rather than suddenly. Therefore, medication information is associated with a long-term time period. On the other hand, a user may want to know how blood pressure changed between days when the antihypertensive drug was taken and days when the antihypertensive drug was not taken. Therefore, medication information is also associated with a short-term time period.

[0061] The display control unit 290 displays the blood pressure information and the element information X on the display screen along the time axis based on the specified unit of time. For example, if the specified unit of time is a week, the display control unit 290 displays the blood pressure information and the element information X selected by the selection unit 280 (e.g., room temperature, sleep information, stress information, medication information, and smoking information) on the display screen along the time axis.

[0062] In another aspect, the selection unit 280 selects element information Y that is not associated with the specified unit period. The display control unit 290 displays the blood pressure information, element information X, and element information Y on the display screen along the time axis based on the specified unit period. In this case, the blood pressure information and element information X are each displayed with priority over the element information Y.

[0063] Specifically, the display control unit 290 displays the blood pressure information and the element information X in preference to the element information Y by graying out the element information Y. Furthermore, the display control unit 290 controls the display order of the blood pressure information, the element information X, and the element information Y so that the blood pressure information and the element information X are displayed in preference to the element information Y. Specific examples of display by the display control unit 290 will be described later.

[0064] <Display Example> Fig. 5 is a diagram showing an example of a display screen of the terminal device 200. Referring to Fig. 5, a display screen 510 is an example of a screen displayed on the display 208 when the specified time period is set to one day. The display screen 510 displays blood pressure information and element information X (here, room temperature, stress information, sleep information, and medication information) associated with each day in chronological order. Specifically, the blood pressure information and element information X for one day (24 hours) are displayed in parallel along the time axis (for example, every hour).

[0065] The display screen 510 includes a bar graph showing blood pressure values, a line graph showing the room temperature at the time of blood pressure measurement, an object showing the presence or absence of stress, an object showing the quality of sleep (good or poor), and an object showing the presence or absence of medication. The top and bottom of the bar graph showing blood pressure values ​​indicate the systolic blood pressure and the diastolic blood pressure, respectively.

[0066] The display screen 510 shows that the patient was stress-free and had good sleep at around 8:00 a.m. It suggests that the patient's blood pressure may have risen due to stress at around 11:00 a.m. It also shows that the patient took medicine at around 12:00 p.m.

[0067] Fig. 6 is a diagram showing another example of the display screen of the terminal device 200. Referring to Fig. 6, a display screen 520 is an example of a screen displayed on the display 208 when the specified time period is a week. The display screen 520 displays one week's worth of blood pressure information and element information X (here, room temperature, stress information, sleep information, and medication information) associated with the week in chronological order. Specifically, the blood pressure information and element information X for one week (7 days) are displayed in parallel along the time axis (e.g., by day).

[0068] Since the same element information X is associated with the daily and weekly units, the display content of the display screen 520 is similar to that of the display screen 510. The blood pressure value for a certain day (e.g., the 8th) indicates the average blood pressure measured on the 8th day. The top and bottom of the bar graph indicate the average systolic blood pressure and average diastolic blood pressure for that day, respectively. Room temperature indicates the average room temperature at the time of blood pressure measurement for that day. Stress information indicates the presence or absence of stress for the entire day. Sleep information indicates the quality of sleep (good or poor) for that day. Medication information indicates whether or not medication was taken on that day.

[0069] The display screen 520 suggests that the blood pressure is relatively high on the 9th due to lack of sleep, on the 11th due to a drop in room temperature, and on the 13th due to stress.

[0070] Fig. 7 is a diagram showing yet another example of the display screen of the terminal device 200. Referring to Fig. 7, a display screen 530 is an example of a screen displayed on the display 208 when the specified time period is set to one year. The display screen 530 displays one year's worth of blood pressure information and element information X (here, temperature, weight, medication information, and salt intake) associated with the year in chronological order. Specifically, the blood pressure information and element information X for one year (12 months) are displayed in parallel along the time axis (e.g., monthly).

[0071] The display screen 530 includes a bar graph showing the average blood pressure value for one month, a line graph showing the average temperature (outdoor temperature) for one month, a line graph showing the average weight for one month, an object showing whether or not the user took medication for one month, and an object showing the average salt intake for one month. The top and bottom of the bar graph show the average systolic blood pressure and average diastolic blood pressure for one month, respectively. The object for salt intake is displayed darker the higher the average salt intake.

[0072] The display screen 530 suggests that blood pressure is on a downward trend due to weight loss, medication, and reduced salt intake, in line with fluctuations in blood pressure caused by changes in outside temperature.

[0073] The same applies to the display screen displayed on the display 208 when the specified time unit is monthly. On the display screen, blood pressure information for one month and element information X associated with the monthly unit are displayed in parallel along the time axis (for example, weekly).

[0074] 5 and 6, only the element information X associated with a short-term unit of time (e.g., room temperature, stress information, sleep information, and medication information) is displayed, and element information Y not associated with the unit of time is not displayed. Similarly, the display screen 530 of Fig. 7, only the element information X associated with a long-term unit of time (e.g., outside temperature, weight, medication information, and salt intake) is displayed, and element information Y not associated with the unit of time is not displayed.

[0075] However, as will be described below, the terminal device 200 may adopt a display method in which element information X is displayed with priority over element information Y.

[0076] Fig. 8 is a diagram illustrating an example of a method for prioritizing display of element information. Referring to Fig. 8, display screen 540 is a screen displayed on display 208 when the specified time period is a week. Display screen 540 displays element information Y (here, outside temperature, weight, and salt intake) in addition to the blood pressure information and element information X (here, room temperature, stress information, sleep information, and medication information) displayed on weekly display screen 520 shown in Fig. 6.

[0077] Here, the blood pressure information and element information X are displayed at the top of the screen, while the element information Y is displayed at the bottom of the screen. Specifically, the processor 202 (display control unit 290) controls the display order so that the blood pressure information and element information X are displayed with priority over the element information Y.

[0078] 9 is a diagram illustrating another example of the element information priority display method. Referring to FIG. 9, a display screen 550 is a screen displayed on the display 208 when the specified time period is set to one week. The same items as those in FIG. 8 (i.e., blood pressure information, element information X, and element information Y) are displayed on the display screen 550.

[0079] However, the element information Y is displayed in gray, making it more difficult to view than the blood pressure information and the element information X. In this way, the processor 202 (display control unit 290) displays the blood pressure information and the element information X in priority over the element information Y by displaying the element information Y in gray.

[0080] According to the display screens 540 and 550, element information X that is highly relevant to the specified time period is displayed with priority over element information Y that is less relevant to the specified time period. This allows the user to easily check element information X that should be noted, and also allows the user to check element information Y as reference information.

[0081] 10 is a flowchart showing an example of a processing procedure of the sphygmomanometer 100. Here, it is assumed that blood pressure measurement is performed by a reduced pressure measurement method, but blood pressure measurement may also be performed by a pressurized measurement method.

[0082] 10 , processor 110 of sphygmomanometer 100 initializes pressure sensor 31 (step S10). Specifically, processor 110 initializes the processing memory area, turns off (stops) pump 32, and adjusts pressure sensor 31 to 0 mmHg (sets atmospheric pressure to 0 mmHg) with valve 33 open.

[0083] The processor 110 closes the valve 33 via the valve drive circuit 330 (step S12), and drives the pump 32 via the pump drive circuit 320 to start pressurizing the cuff 20 (fluid bag 22) (step S14). At this time, the processor 110 controls the inflation speed of the cuff pressure, which is the pressure inside the fluid bag 22, based on the output of the pressure sensor 31, while supplying air from the pump 32 to the fluid bag 22 through the air piping.

[0084] The processor 110 determines whether the cuff pressure has reached or exceeded the threshold value P (step S16). Typically, the threshold value P is set to a value 30 mmHg to 40 mmHg higher than the expected maximum blood pressure (systolic blood pressure).

[0085] 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 equal to or 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). This causes a transition from the pressurization process to the depressurization process, and the cuff pressure is gradually reduced.

[0086] During this decompression process, processor 110 extracts a pulse wave signal from the cuff pressure signal detected by pressure sensor 31, attempts to calculate systolic blood pressure and diastolic blood pressure based on the pulse wave signal, and determines whether blood pressure calculation is complete (step S22). If blood pressure calculation is not complete (NO in step S22), processor 110 repeats the processes of steps S20 and S22. If blood pressure calculation is complete (YES in step S22), processor 110 fully opens valve 33 (step S24) and performs control to rapidly exhaust air from cuff 20.

[0087] The processor 110 measures the room temperature via the temperature sensor 54 (step S26) and displays the blood pressure values ​​and other data measured in the blood pressure measurement on the display 50 (step S28). The processor 110 transmits the blood pressure information and data such as the room temperature to the terminal device 200 via the communication interface 53 (step S30). The blood pressure information and data such as the room temperature are stored in the memory 51 of the sphygmomanometer 100.

[0088] 11 is a diagram showing an example of a processing procedure of the terminal device 200. Referring to FIG. 11, the processor 202 of the terminal device 200 receives data such as blood pressure information and room temperature via the communication interface 210 (step S50). The processor 202 stores the data in the memory 204 (step S52). The processor 202 accepts an input to start a management application via the input device 206 and starts the management application (step S54). The processor 202 acquires various element information using the acquisition method described above (step S56).

[0089] The processor 202 accepts input specifying a period unit via the input device 206 (step S58). The processor 202 displays the blood pressure information and element information along the time axis on the display 208 based on the specified period unit (step S60). For example, the processor 202 displays display screens 510 to 550 on the display 208. The processor 202 determines whether an instruction to terminate the management application has been received via the input device 206 (step S62). If the instruction to terminate has not been received (NO in step S62), the processor 202 returns to step S58. If the instruction to terminate has been received (YES in step S62), the processor 202 terminates the processing. For example, the processor 202 transitions to background operation and executes steps S50, S52, etc.
