Technical field

The present invention relates to an electronic blood pressure monitor, and more particularly, to an electronic blood pressure monitor having a guide function for an operation switch.

Conventional technology

At present, devices for measuring blood pressure at home are rapidly spreading. Blood pressure is one of the indicators of interpreting circulatory disease. Performing a risk analysis based on blood pressure is effective for preventing cardiovascular diseases such as stroke, heart failure and myocardial infarction.

Such a risk analysis needs to be performed based on the result of blood pressure measurement on the same conditions for at least 1 week or longer period. Thus, an electronic blood pressure monitor having a function of recording a plurality of measurement results has been provided. Some conventional electronic blood pressure monitors have a function of storing a plurality of measurement results and a function of storing a measurement result for each measured condition such as morning or night.

The electronic blood pressure monitor disclosed in Japanese Patent Laid-Open No. 2002-272686 is also used for a plurality of users. Specifically, when the button for switching the user is operated, the electronic blood pressure monitor stores the measured blood pressure value of the user in the memory area for the user designated by the switching.

In a conventional blood pressure monitor, for example, a blood pressure monitor capable of storing the measurement results of a plurality of people, a method of designating a person to be measured is adopted by a user operating a switch before or after the measurement. Similarly, in the blood pressure monitor which stores the measurement result for each measured condition, the measurement condition is specified by the user operating a switch before or after the measurement. In these methods, the operation result of the operation switch, for example, the selected user or the selected measurement condition is displayed on the liquid crystal display. However, since the display unit and the operation switch are independent and separated from each other, the user operates the display contents and the switch operated. It becomes difficult to intuitively associate Therefore, for example, in a sphygmomanometer in which a plurality of users can be set, the risk analysis of the user's disease will be effective for each user who is selectively designated by the switch operation based on the blood pressure value stored for a long time. In the case where the measurement is performed without noticing the wrong user selection, the measured data stored for a long time becomes invalid data for risk analysis.

For example, in Japanese Patent Laid-Open No. 2002-272686, when a button for instructing a user to switch is operated, an identification symbol of the new user who is switched is displayed. However, since the positional relationship between the aspect of the identification mark and the switch button is not considered, the identification symbol is displayed at a position away from or unrelated to the switch button. Therefore, the user may easily overlook the displayed identification symbol and may measure blood pressure without realizing that the user selection operation is wrong.

An object of the present invention is to provide an electronic blood pressure monitor that can prevent misoperation.

In order to achieve the above object, an electronic sphygmomanometer according to an aspect of the present invention includes a cuff attached to a blood pressure measurement site, a pressure adjusting unit for adjusting a pressure applied to the cuff, a pressure detector for detecting a pressure in the cuff, and a pressure; And a blood pressure calculator for calculating the blood pressure value based on the detection signal output from the detection unit, a storage unit for storing the calculated blood pressure value, a display unit for displaying at least the blood pressure value, and a plurality of operation units. The display unit has an operation display unit for displaying information corresponding to the operation of the operation unit with respect to each of the operation units. An operation display section relating to each operation section and the corresponding operation section in the display section is disposed to be adjacent.

Therefore, since the user can confirm the information in response to the operation at a position close to the operation portion, it is possible to know quickly and reliably that it is an incorrect operation, thereby making it possible to reliably and easily prevent the wrong operation. Therefore, the reliability of the measurement record of blood pressure measured over a long period of time is improved, and the data is effective for analyzing the risk of disease.

An electronic sphygmomanometer according to another aspect of the present invention is based on a cuff mounted on a blood pressure measurement site, a pressure adjusting unit for adjusting a pressure applied to the cuff, a pressure detector for detecting pressure in the cuff, and a detection signal output from the pressure detector. And a blood pressure calculator for calculating the blood pressure value, a storage unit for storing the calculated blood pressure value, a display unit for displaying at least the blood pressure value, and a plurality of operation units. The display unit has an operation display unit for displaying information corresponding to the operation of the operation unit with respect to each of the operation units. An operation display section corresponding to each operation section is arranged in accordance with the arrangement of the plurality of operation sections.

Therefore, since the user can confirm the information according to the operation unit to be operated at the position according to the arrangement of the operation unit, the user can know quickly and reliably that it is a misoperation. As a result, it is surely and easily prevented from erroneous operation.

An electronic sphygmomanometer according to another aspect of the present invention includes a cuff attached to a blood pressure measurement site, a pressure adjuster for adjusting a pressure applied to the cuff, a pressure detector for detecting pressure in the cuff, and a detection signal output from the pressure detector. A blood pressure calculator that calculates a blood pressure value based on the memory, a storage unit that stores the calculated blood pressure value, a display unit that displays at least the blood pressure value, and a plurality of operation units. The display unit has an operation display unit for displaying information corresponding to the operation of the operation unit with respect to each of the operation units. For each type of operation, an operation unit for the operation and an operation display unit relating to the operation unit are arranged separately.

Therefore, since the user can confirm the information according to the operation unit to be operated at the position according to the same division as the operation unit for each type of operation, it is possible to know quickly and reliably that it is an incorrect operation. As a result, it is surely and easily prevented from erroneous operation.

In any of the above-described electronic blood pressure monitors, the operation display unit is provided on the display unit. Therefore, since the operation display portion can be configured using the portion of the display of the blood pressure value, the structure of the electronic blood pressure monitor is not complicated and inexpensive rather than providing a separate display area for the operation display portion. In addition, the failure can be reduced.

Preferably, the electronic blood pressure monitor is shared by a plurality of subjects. The plurality of operation units includes an operation unit operated to instruct the discrimination of the subject. Therefore, it is possible to know quickly and surely after the operation whether or not the distinction of the subject is incorrectly indicated by the operation.

Preferably, the electronic blood pressure monitor has a measurement mode of blood pressure and a call mode for reading the blood pressure value in the storage unit and displaying the read blood pressure value as an operation mode. The plurality of operation units include an operation unit operated to designate either the measurement mode or the call mode as the operation mode. Therefore, it is possible to know quickly and surely after the operation whether the operation of designating the operation mode of the electronic blood pressure monitor is wrong by the operation.

Preferably, the storage unit stores the blood pressure value calculated by the blood pressure measurement in association with the condition of the blood pressure measurement. The plurality of operation units include an operation unit operated to instruct to call the blood pressure value associated with the desired condition from the storage unit. Therefore, it is possible to know quickly and reliably after the operation whether or not the instruction operation of the measurement condition of the blood pressure value to be called is wrong.

The control unit 16 has a central processing unit (CPU) 161 and input ports 71, 72A, 72B, 73, and 74 that control respective parts of the main body 61. The control unit 16 further includes an operation detection unit 162, a blood pressure calculator 163, a display control unit 164, and a memory control unit 165 that operate under the control of the CPU 161. The operation detection unit 162 detects (discriminates) the type of the switch operated by the operation unit 4 or the presence or absence of the operated switch. The blood pressure calculator 163 calculates the blood pressure and the pulse. The display control unit 164 controls the display operation of the display unit 2. The memory control unit 165 has a function of accessing the memory 13. The functions of the operation detection unit 162, the blood pressure calculating unit 163, the display control unit 164, and the memory control unit 165 allow the CPU 161 to read a predetermined program stored in the memory 13 in advance, It is realized by executing the program. Here, the functions of these parts are realized by a program, but all or part of the functions may be realized by hardware such as a circuit.

Although illustration of the clock setting switch 47 is abbreviate | omitted to the operation part 4 of FIG. 4, when the clock setting switch 47 is operated, the CPU 161 will store the time data of the timer 14, and the clock setting switch ( The setting is made in accordance with the operation of 47).

The power supply unit 15 has a battery which is not shown, which can be charged. The power supply unit 15 supplies power to the control unit 16 including the CPU 161 from the battery while the power supply cable 18 is not connected to the connector unit 20. When the power cable 18 is connected to the connector portion 20, the power supplied from an external alternating current (AC) power supply via the power cable 18 is supplied to each part of the main body 61 by the power supply portion 15. In addition to being supplied, it is also used to charge the battery. In addition, the power supply unit 15 may be made of an alkaline battery instead of a rechargeable battery. In that case, while the power cable 18 is not connected to the connector unit 20, electric power is supplied from the battery to the control unit 16 including the CPU 161. When the power cable 18 is connected to the connector portion 20, the power supplied from the external AC power supply through the power supply cable 18 is supplied to each part of the main body 61 by the power supply unit 15, The battery is electrically separated from each part of the main body 61.

Since a plurality of people share the electronic blood pressure monitor 1, the memory 13 has a storage area of the measurement result for each user individually. Since it is assumed here that the electronic blood pressure monitor 1 is shared by two people, it has areas 13A and 13B for storing the measurement result for each user (the subject). As shown in Fig. 5, each of the storage areas 13A and 13B includes blood pressure measurement result data DAi (i = 1, 2, 3 ..., i, ..., m) and measurement condition data DBi (i). = 1, 2, 3 ..., i, ..., m) are stored in association. Blood pressure measurement result data (DAi) are the highest blood pressure (Systolic Blood Pressure (mmHg): abbreviated as SYS in the drawing), the lowest blood pressure (Diastolic Blood Pressure (mmHg): abbreviated as DIA in the drawing), pulse rate per minute (Pulse Rate: abbreviated as PULSE in the drawing) and measurement time (abbreviated as TIME in the drawing). For example, the measurement condition data DBi indicates either "morning" or "night" when blood pressure measurement is performed. Or it shows either after a weather or before going to bed. Or either before or after dosing. Or it shows either before exercise or after exercise. Or it represents either weekend or weekday. As an example, the distinction of morning or night is assumed as a measurement condition.

The measurement condition of "morning / night distinction" is temporarily stored in the memory 13 as the condition data 13C. When the CPU 161 determines that the measurement time data input from the timer 14 corresponds to a predetermined period indicating morning, the condition data 13C is set to indicate 'morning' and corresponds to a predetermined period of night. If so, it is set to indicate 'night'. It is also assumed that the data of the predetermined time indicating the morning and the data of the predetermined time indicating the night are stored in the memory 13 in advance. Therefore, the CPU 161 determines the measurement condition by comparing the data of the predetermined time read from the memory 13 with the measurement time data input from the timer 14.

Referring to FIGS. 3 and 4, the operation unit 4 includes a power switch 41, user select switches 42A and 42B operated to distinguish the subject, start of pressurization (start of measurement) or stop (measurement). Recalling the measurement switch 43, the clock setting switch 47, and the stored measurement result data (reading the measurement result data from the memory 13, and reading the display unit 2) operated to instruct A recording call switch 44, and a morning switch 45 and a night switch 46, which are operated to display one measurement result data.

The morning switch 45 and the night switch 46 are operated to designate the data to be called when the stored measurement result data is called. That is, the measurement result data of the call target is manipulated to specify whether the morning / night distinction is data indicating 'morning' or data indicating 'night'.

When the user selection switch 42A or 42B is operated, either of the storage areas 13A and 13B is designated as the storage area to store the measurement result data according to the operated switch, or the storage area to be retrieved for the call. . The storage area 13A is designated when the user selection switch 42A is operated, and the storage area 13B is designated when the user selection switch 42B is operated.

The power switch 41 is operated to turn on / off the power supply for the operation from the power supply unit 15 to be described later to each part (except the control unit 16). Therefore, if the power switch 41 is operated during the operation, the operation is stopped (ended).

In the operation unit 4 of FIG. 4, for explanation, a user select switch group 42 consisting of a power switch 41, user select switches 42A and 42B, a measurement switch 43, and a recording call switch 44 are provided. Shown.

The control unit 16 has the input ports 71 to 74 as described above. The input port 71 is connected to the power switch 41 to input a signal that the power switch 41 is operated to output. The input ports 72A and 72B are connected to each of the user selection switches 42A and 42B to input signals outputted by operating the connected switches. The input port 73 is connected to the measurement switch 43, and inputs the signal which the measurement switch 43 operates and outputs. The input port 74 is connected to the write call switch 44 so that the write call switch 44 is operated to input an output language signal. The signal given to each input port is detected by the CPU 161.

The signal given to each of the input ports 71 to 74 is a pulse signal having a predetermined time width. Specifically, the pulse signal changes from " 0 " to " 1 " when the corresponding switch is operated, and then extremely short. The signal is maintained at the predetermined period level " 1 " and changed to " 0 " after the end of the period. When the CPU 161 detects that one of the input ports is given a pulse signal, it determines (detects) that the switch connected to the corresponding input port has been operated.

FIG. 6 is a flowchart illustrating the operation (blood pressure measurement operation, measurement data call operation) of the electronic blood pressure monitor 1 according to the present embodiment. The flowchart shown in FIG. 6 is stored in a predetermined area of the memory 13 as a program in advance, and is read and executed by the CPU 161.

In the order of FIG. 6, the operation will be described with reference to FIGS. 7 to 11. In addition, beforehand, a person under test assumes that at the time of blood pressure measurement, the air tube 3 is connected to the air connector 31, and the cuff 5 is wound around a measurement site | part. In addition, the person to be measured inserts the plug 17 into the connector part 20 previously, and assumes that the power supply cable 18 is connected to an AC power supply, and electric power is supplied to each part of the main body 61. FIG. When the blood pressure measurement data is called, the person to be measured inserts the plug 17 into the connector portion 20 and connects the power cable 18 to the AC power supply. However, since the cuff 5 is not required to be attached, In some cases, the air tube 3 is connected to the air connector 31 and the cuff 5 is not wound.

In FIG. 7 to FIG. 11, as shown in FIG. 3, the cuff 5 is connected to the main body 61 and the power cord 18 is connected. However, these connections are omitted for simplicity. Doing.

In this state, the subject prepares the electronic blood pressure monitor 1 and opens the body cover 60 as shown in FIG. 7. At this time, nothing is displayed on the display unit 2. Then, the subject operates the power switch 41 to supply power to each part of the electronic blood pressure monitor 1 to start the operation (step S (hereinafter, simply abbreviated as S) 1). The operation detection unit 162 detects that the power switch 41 has been operated based on the signal level input to the input port 71. According to the detection result, the CPU 161 initializes the working memory (not shown), controls each part, exhausts the air in the air bag of the cuff 5, and Correction is performed so that the output is 0 mmHg (S2).

Thereafter, the display control unit 164 informs the area 2A of the display unit 2 in order to inform that the power is turned on and the power is supplied to each part to enable the operation (blood pressure measurement or call of the measurement data). In FIG. 8, data as shown in FIG. 8 is displayed. The measurement subject who saw the said indication can confirm that electric power was supplied to each part by operating the power switch 41 (S3).

Thereafter, the CPU 161 moves to the switch input wait state until any switch operation is detected by the operation detection unit 162 (S8) (S7). In the switch input standby state, the operation detection unit 162 detects that one switch has been operated by the subject to measure based on whether the signal level of any one of the input ports 71 to 74 changes. (S8). While the operation detection unit 162 determines that the operation has been performed on the basis of the input port discrimination in which the signal level has changed, it is a switch other than the user selection switches 42A and 42B and the power switch 41 ( Switch '), the switch input standby state (S7).

When the operation detection unit 162 determines that a pulse signal is given to the input port 71 corresponding to the power switch 41 ('power switch' in S8), the CPU 161 determines a series of values based on the determination. The process ends. As a result, this operation is forcibly terminated.

On the other hand, when it is determined by the operation detection unit 162 that the pulse signal is input to the input port 72A or 72B ('user selection switch' in S8), the following operation is performed. That is, when it is determined that the pulse signal is given to the input port 72A, the memory control unit 165 sets the user to "A", that is, the recording destination and the calling destination of the measurement result, according to the determination. ) When it is determined that a pulse signal is given to the input port 72B, the memory control unit 165, based on the determination, sends the user "B", that is, the recording destination and the calling destination of the measurement result to the storage area 13B. Specify. The display control part 164 displays the result of the determination of the operation detection part 162, ie, the designation of the storage area which should be used as a recording destination and a call destination of the measurement result, to the display part 2, for example, as shown in FIG. It is also displayed (S9).

In FIG. 9, the display control unit 164 displays " 0 " in the display area 2A of the display unit 2 to indicate that the state in which the measurement operation or the call of the measurement result data can be performed is summarized. In addition, in the display area 2B, by the display control unit 164, an icon (pattern, figure, character, etc.) instructing the user 'A' is displayed, indicating that "A" is selected as the user. Thereby, the subject can know that the correct user selection is set in the electronic blood pressure monitor 1, and it can also know that it became the state which can be operated.

Thereafter, the CPU 161 moves to the switch input wait state (S10). The switch input wait state is continued until the operation determination part 162 detects that a pulse signal is given to any one input port. When a pulse signal is given to any one of the input ports, the operation determining unit 162 determines what switch corresponding to the pulse signal is based on the input port discrimination (S11). If it is determined that the pulse signal is given is the input port 71 ('power switch' in S11), on the basis of the result of the determination, the CPU 161 causes the power supply unit 15 to stop supplying power to each part. In order to instruct, the power supply to each part by the power supply part 15 stops. Therefore, the display disappears as shown in FIG. Then, the series of processing ends.

On the other hand, if it is determined that the pulse signal is given to the input port 73 ('measurement switch' in S11), the CPU 161 will follow the data display as shown in FIG. 10 based on the result of the determination. The process of blood pressure measurement (described later) is started.

When a pulse signal is given to input ports other than the input ports 71 and 73, the operation determining unit 162 determines that the switches other than the measurement switch 43 and the power switch 41 have been operated ( 'Other switches' in S11). Then, the type of the operated other switches is determined (S18). That is, if the input port given the pulse signal is the input port 72A or 72B, it is determined that the user (the subject) is already switched by the switch operation of S8 ('user selection switch' in S18). Based on the result of the determination, the display control unit 164 switches the display of the user's distinction in the display area 2B so that the pulse signal indicates the user's distinction corresponding to the given input port (S19).

Then, the memory control unit 165 switches the user's setting on the basis of the determination result of the operation determination unit 162 (S20). For example, when a pulse signal is given to the input port 72A, the user sets " A ", that is, the recording destination and the calling destination of the measurement result to the storage area 13A. When a pulse signal is given to the input port 72B, the user is switched to "B", that is, the recording destination and the calling destination of the measurement result are set in the storage area 13B. After that, the process returns to S10 and the CPU 161 shifts to the switch input standby state.

On the other hand, if it is determined that the pulse signal is given to the input port 74 ('record call switch' in S18), the display control unit 164, according to the result of the determination, write call mode for calling the recorded measurement result data. In order to specify that is set, the character of 'record' is displayed in the display area 2C (S21). Thereafter, the subject operates one of the morning switch 45 and the night switch 46 to designate the measurement result data of morning or night as the data to be called (S22). The operation detection unit 162 determines which switch is operated at this time. Based on the result of the determination, the display control unit 164 determines whether the measurement result data called in the display area 2A is 'morning' or 'night', and displays the determination result in the display area 2C. Add and display (S23).

Next, the memory control unit 165 reads the blood pressure measurement result from the memory 13, and the read measurement result is displayed on the display area 2A by the display control unit 164 (S24). That is, the memory control unit 165 indicates 'morning' or 'night' designated in S22 from any one of the storage areas 13A and 13B corresponding to the user 'A' or user 'B' set in S8 or S20. The measurement result data DAi corresponding to the measurement condition data DBi to be read are read out, and the display control unit 164 displays the read measurement result data in the display area 2A. An example of the display aspect in this case is shown in FIG. Thereafter, the processing returns to the processing of staff S10.

Next, the operation of blood pressure measurement after S12 will be described.

Since the person to be measured operates the measurement switch 43 ('measurement switch' in S11), the CPU 16 shifts to the blood pressure measurement mode. In accordance with the transition to the measurement mode, the display control unit 164 displays the character of 'measurement' in the display area 2C (S12). In this way, the person to be measured can know that the apparatus has moved to a state in which blood pressure can be measured as instructed.

Next, the CPU 161 controls each part to gradually pressurize the pressure in the air bag to the maximum blood pressure of the subject to about +40 mmHg (S13), and then gradually reduces the pressure in the air bag (S14). ). Since the pressure in the air bag is detected by the pressure sensor 7 and the amplifying circuit 8 in this depressurization process, the blood pressure calculating section 163 uses the blood pressure (highest blood pressure and The minimum blood pressure) value and the pulse rate are calculated and stored temporarily in an internal memory (not shown) of the CPU 161 (S15). The display control unit 164 displays the calculated blood pressure value and pulse rate on the display area 2A of the display unit 2 (S16). Pressurization / decompression processing for blood pressure measurement is the same as that of the conventional electronic blood pressure monitor. In addition, although blood pressure measurement is made here in a decompression process, you may make it perform in a pressurization process. During measurement, the blood pressure values detected (calculated) in order are displayed while being updated in the display area 2A as shown in FIG. 10.

When the calculation and display of the blood pressure and the pulse are completed, the CPU 161 acquires the measurement time data based on the time data given from the timer 14. The condition data 13C is set to 'morning' if the acquired time data corresponds to a predetermined time zone of 'morning', and is set to 'night' if it corresponds to a predetermined time slot of 'night'. Then, the acquired measurement time data is correlated with the condition data 13C read out from the memory 13 and the data indicating the blood pressure (highest blood pressure and lowest blood pressure) value and pulse rate read out from the internal memory of the CPU 161. The memory control unit 165 stores these associated data as the measurement result data DAi and the measurement condition data DBi in the storage area 13A or 13B set as a recording destination (storage destination) in S8 or S20. (S17). This completes the series of blood pressure measurement and returns to S10.

In this way, data in response to the operation of the various switches in S3, S9, S12, S19, S21, and S23 is displayed in the areas 2A, 2B, and 2C provided in proximity to the various switches to be operated. By operating, the instruction given to the electronic blood pressure monitor 1 or the operation of the electronic blood pressure monitor 1 set by the instruction becomes easy. Therefore, since the operation myth can be known quickly, it becomes easy to prevent a wrong operation.

(Another example of display area)

Another arrangement example of the display area of the display unit 2 will be described with reference to FIG. 12. Here, an area for displaying information corresponding to the operation of each operation switch is arranged in accordance with the arrangement of the operation switches.

In FIG. 12, the areas 2A, 2B, 21C, 22C, and 23C displaying data in response to the operation of various switches are arranged (arranged) to be the same as the corresponding arrangement according to the arrangement (arrangement) of the various switches to be operated. . In the area 2B, data in response to the operation is displayed in the same arrangement as the adjacent user selection switches 42A and 42B. In Fig. 12, since the user-selected switch 42A on the left side has been operated, the letter 'A' is displayed on the left side in the display area 2B.

The area 21C also displays data corresponding to the operation in the same arrangement as the adjacent morning switch 45 and night switch 46. In FIG. 12, since the night switch 46 on the right side is operated, the letter 'night' is displayed on the right side in the display area 21C.

Further, in the area 22C, data corresponding to the operation of the adjacent write call switch 44 is displayed. When the recording switch 44 is operated, the character of 'recording' is displayed on the right side of the area 22C.

In the region 23C, when the adjacent measuring switch 43 is operated, a letter of 'measurement' is displayed.

(Another example of display area)

Another arrangement example of the display area of the display unit 2 will be described with reference to FIG. 13.

In FIG. 13, the display area 2B is provided closer to the user selection switches 42A and 42B. Regions 21B and 22B of the display region 2B are provided according to the same arrangement as the switches 42A and 42B. In the areas 21B and 22B, data in response to the operation is displayed. In Fig. 13, since the user selection switch 42A on the left side has been operated, the letter 'A' is displayed on the display area 21B on the left side.

Although this embodiment assumed the case where a plurality of people can share the electronic blood pressure monitor 1, even if it cannot share, ie, even when the memory area of a measurement result is not provided in the memory 13 for every individual, It is possible to apply likewise. In that case, the user selection switch group 42 of the operation part 4 and the display area 2B of the display part 2 are not provided.

In addition, in the display area 2C or 22C, the recording call mode or the measurement mode of the blood pressure can be displayed to notify the subject of the current operation mode of the electronic blood pressure monitor 1.

Here, the area 2C is displayed when the blood pressure measurement result data is stored in the memory 13 or when the measurement result data is called from the memory 13, that is, when the processing of S17 or S24 in FIG. 6 is executed. The display mode of the data is changed (change of color, change from lit to flash, change from flash to lit, or erase). In this way, the subject can be notified that the switch operation is prohibited. In this way, an external factor such as switch operation can be prevented from occurring while data in the memory 13 is being accessed. Therefore, the external factor prevents normal access to the memory 13, and as a result, it is possible to prevent a failure such as data destruction.

While the present invention has been described and illustrated in detail, it is to be understood that this is for illustration only and should not be taken as limiting, the spirit and scope of the invention being limited only by the appended claims.

According to the present invention, an electronic blood pressure monitor that can prevent misoperation can be provided.
