A biological information display device of the present invention calculates and displays a statistical value of the measurement results for a plurality of times regarding biological information. In the present specification, the “biological information” is used in a treatment policy by a medical specialist (medical staff), checking of a trend, and the like, and includes at least one of blood pressure information and a body composition (body fat percentage, basal metabolism, etc.).

First, the outer appearance and the configuration of the biological information display device according to a first embodiment of the present invention will be described. In the present embodiment, description will be made assuming that the biological information relates to blood pressures (systolic blood pressure and diastolic blood pressure).
With reference to
The operation unit 41 includes, for example, a power switch 41A for receiving an input of an instruction to turn ON or OFF the power, a measurement switch 41B for receiving an instruction to start measurement, a set switch 41C for receiving an instruction for various types of setting processes and readout of stored values, and a cursor switch 41D. The cursor switch 41D includes a leftward switch 411, a rightward switch 412, an upward switch 413, a downward switch 414, and a determination switch 415.
The main body 10 of the biological information display device 1 is mounted on a desk or a dedicated stand in an examination room.
With reference to
In addition to the display unit 40 and the operation unit 41 described above, the main body 10 includes the air system 30, a CPU (Central Processing Unit) 100 for controlling each unit in a concentrated manner and for carrying out various calculation processes, a memory 42 for storing programs causing the CPU 100 to perform predetermined operations and various data, a non-volatile memory (e.g., flash memory) 43 for storing a measured blood pressure, a power supply 44 for supplying power to the CPU 100, a timer unit 45 for performing a timing operation, and a data input/output unit 46 for receiving an input of data from the outside.
The air system 30 includes a pressure sensor 32 for detecting a pressure (cuff pressure) in the air bag 21, a pump 51 for supplying air to the air bag 21 in order to increase the cuff pressure, and a valve 52 that opens and closes to exhaust or enclose the air in the air bag 21.
The main body 10 also includes an oscillation circuit 33, a pump drive circuit 53, and a valve drive circuit 54 in association with the air system 30 described above.
The pressure sensor 32 is a capacitance type pressure sensor, where the capacitance value changes according to the cuff pressure. The oscillation circuit 33 outputs to the CPU 100 a signal of an oscillating frequency corresponding to the capacitance value of the pressure sensor 32. The CPU 100 converts the signal obtained from the oscillation circuit 33 to a pressure and detects the pressure. The pump drive circuit 53 controls the drive of the pump 51 based on a control signal provided from the CPU 100. The valve drive circuit 54 performs the open/close control of the valve 52 based on a control signal provided from the CPU 100.
The pump 51, the valve 52, the pump drive circuit 53, and the valve drive circuit 54 configure an adjustment unit 50 for adjusting the cuff pressure. It should be recognized that the device for adjusting the cuff pressure is not limited thereto.

Although the cuff 20 includes the air bag 21, a fluid supplied to the cuff 20 is not limited to air and may be a liquid or a gel. Alternatively, the fluid is not the sole case, and uniform fine particles such as microbeads may be used.
With reference to
The measurement processing unit 102 is connected to the oscillation circuit 33, the pump drive circuit 53, and the valve drive circuit 54, and performs a process for measuring blood pressure values (systolic blood pressure and diastolic blood pressure) of a person to be measured according to a predetermined algorithm. Suppose that the algorithm for calculating the blood pressure does not include the correction algorithm for smoothening a pulse wave amplitude. In the present embodiment, the measurement processing unit 102 executes continuous measurements for a predetermined number of times, but this is not the sole case. The measurement processing unit 102 stores measurement result data including the measured blood pressure values in the flash memory 43. The data structure of the flash memory 43 will be described later.
The measurement processing unit 102 calculates the blood pressure values according to the oscillometric method. First, the blood pressure calculation method by the oscillometric method will be briefly described with reference to
The blood flow arrests when the inner pressure of the cuff becomes higher than the systolic blood pressure, and the blood flow resumes when the pressure is gradually released. The oscillometric method uses the characteristics that the pulse wave amplitude changes in the process as shown in
With reference to
When the maximum point of the pulse wave amplitude is detected, a value obtained by multiplying a predetermined constant (e.g., 0.5) to the maximum point AMAX is assumed as a threshold value TH_SYS, and a value obtained by multiplying a predetermined constant (e.g., 0.7) to the maximum point AMAX is assumed as a threshold value TH_DIA. The cuff pressure higher than the average blood pressure (MAP) and corresponding to the point where an envelope curve 600 of the pulse wave amplitude and the threshold value TH_SYS intersect is determined as s systolic blood pressure (“SYS” in the figure). The cuff pressure lower than the average blood pressure (MAP) and corresponding to the point where the envelope curve 600 of the pulse wave amplitude and the threshold value TH_DIA intersect is determined as a diastolic blood pressure (“DIA” in the figure).
As apparent from this figure, the shape of the envelope curve of the pulse wave amplitude influences the accuracy of the blood pressure value calculation in the oscillometric method. In
The existence of the abnormal pulse wave amplitude ER as shown in
In the present embodiment, when a plurality of measurement results as targets are displayed before the calculation of the statistical value, determination of a measurement result not suitable for the calculation of the statistical value can be made out of the plurality of displayed measurement results. In the present embodiment, the measurement result specified as an eliminating target by the user is not used for the calculation of the statistical value, but the calculation can be redone as many times as required even in a case where the determination is wrongly made by not deleting from the memory (flash memory 43). As a result, the diagnosis of the person to be measured by the medical staff can be supported since an accurate statistical value can be calculated. The medical staff can safely perform the operation for specification since the measurement result specified as the eliminating target is not deleted from the memory.
Referring again to
The specification control unit 104 includes a specification processing portion 116. When the above result information is displayed, the specification processing portion 116 executes a process for specifying the second measurement result to be used in the calculation of the statistical value based on an instruction signal from the operation unit 41. More specifically, a plurality of blood pressure value data (also referred to as “second blood pressure value data”) to be used in the calculation of the statistical value is specified out of the first blood pressure value data for the predetermined number of times. When a predetermined instruction is input by the operation unit 41, the specification processing portion 116 can reset the specification regarding the second blood pressure value data.
In
The statistical value calculating unit 106 calculates the statistical value of the second measurement result specified by the specification processing portion 116. The calculated statistical value is displayed on the display unit 40.
The operation of each functional block described above may be realized by executing software stored in the memory 42, or at least one may be realized by hardware.
With reference to
Specifically, the measurement processing unit 102 executes an initialization process (step S102). Particularly, a predetermined region of the memory 42 is initialized, the air in the air bag 21 is exhausted, and correction of the pressure sensor 32 is performed. When the measurable state is then realized, the measurement processing unit 102 starts to drive the pump 51 and gradually increases the cuff pressure of the air bag 21 (step S104).
When the cuff pressure reaches a predetermined level for blood pressure measurement in the gradually pressurizing process, the measurement processing unit 102 gradually decreases the cuff pressure (step S106). Specifically, the pump 51 is stopped and the closed valve 52 is gradually opened to gradually exhaust the air in the air bag 21. The measurement processing unit 102 acquires a signal from the oscillation circuit 33 and detects the cuff pressure during the depressurization period. The detected cuff pressure data is then recorded in time-series in an internal memory. In the present embodiment, the pulse wave is measured in the course of decreasing the cuff pressure but may be measured in the course of increasing the cuff pressure.
The measurement processing unit 102 extracts the pulse wave amplitude (pulse wave amplitude value for a plurality of beats) as a vibration component from the measured pulse wave according to the oscillometric method described above, and calculates blood pressure values (systolic blood pressure and diastolic blood pressure) and the number of pulse beats (step S108). Each extracted pulse wave amplitude value is stored in the internal memory in correspondence with the cuff pressure data or the time data. After the blood pressure values are calculated, the measurement result for this time is stored in a corresponding measurement result storage region of the flash memory 43 (step S109).
An example of a data structure in the flash memory 43 in the present embodiment is shown in
In step S109 of
An example of a data structure of the pulse wave related information 83 is shown in
With reference again to
The statistical process will be described with reference to the sub-routine of
With reference to
The specification control unit 104 then displays the calculated average values and the measurement result list on the display unit 40 (step S202). The example of screen display is shown in
With reference to
The medical staff can decide whether or not there is a blood pressure that is abnormal or that is not suitable for the calculation of the statistical values by looking at the six pieces of measurement data configuring the measurement result list 62.
The specification control unit 104 then determines whether or not a data selecting instruction is input through the operation unit 41 (step S203). If the data selecting instruction is not input (NO in step S203), the process is terminated.
When the data selecting instruction is input (YES in step S203), the specification processing portion 116 of the specification control unit 104 receives specification of the measurement data as an eliminating candidate from the medical staff (step S204). The examples of display screens upon receiving the specification of the measurement data as the eliminating candidate are shown in
When the determination switch 415 is pushed, for example, while the measurement data 70 is selected, the specification processing portion 116 preferably reads out the pulse wave related information 83 corresponding to the measurement data 70 from the flash memory 43 and displays the screen as shown in
In
A button 73A for confirming that the selected measurement value is set as the eliminating target and a button 73B for confirming that the selected measurement value is not set as the eliminating target are displayed under the graph 72. For instance, when the button 73A is pushed (YES in step S206), the measurement value without having the eliminating flag, that is, the measurement value specified by the user, is specified as the measurement value to be used in the calculation of the average values by the specification processing portion 116. The statistical value calculating unit 106 then calculates the statistical values for the plurality of measurement values with the selected measurement value being eliminated (step S208). Specifically, calculated are the average values of the respective measurement values (systolic blood pressure, diastolic blood pressure, and the number of pulse beats) without having the eliminating flags. The calculated average values are displayed on the display unit 40 (step S210).
When the button 73B shown in
After step S210, the specification control unit 104 determines whether or not the instruction for termination is input (step S212). When determined that the instruction for termination is input (YES in step S212), the statistical process is terminated. When the instruction for termination is not input (NO in step S212), the process proceeds to step S214.
In step S214, the specification control unit 104 determines whether or not the instruction for reset is input. When determined that the instruction for reset is input (YES in step S214), the eliminating flag is cleared to be reset into a state with no eliminating target (step S216), and the process returns to step S204. When the instruction for reset is not input (NO in step S214), the process returns to step S204 without clearing the eliminating flag.
Thus, in the present embodiment, the eliminating target can be specified as many times as required even if erroneously determined as the eliminating target since the measurement result data itself eliminated from the calculation of the average values is not deleted from the flash memory 43. Furthermore, the medical staff can easily determine whether or not the corresponding blood pressure value is abnormal data since the graph of the pulse wave amplitude used in the calculation of the blood pressure value is also displayed in addition to the blood pressure value when selecting the eliminating target.
In the present embodiment, the measurement result data may be automatically deleted only when the flash memory 43 has a predetermined capacity. In such a case, the oldest data may be deleted, for example.
In the above-described embodiment, the graph of the pulse wave amplitude value is displayed only for the selected blood pressure value, but the graph of the pulse wave amplitudes for N times may be displayed at once in addition to/in place of the blood pressure values for N times in a case where the display region of the display unit 40 is large. Furthermore, the graph of the pulse wave amplitude value is displayed in the present embodiment, but the filtered pulse wave may be alternatively displayed along the time axis.
In the flowchart of
In the present embodiment, the measurement data as the eliminating target is selected by the medical staff, but the measurement data to be used in the calculation of the average value out of the measurement data for N times may be selected by the medical staff.
Furthermore, in the present embodiment, the measurement results for N times are displayed after the termination of the continuous measurements for N times and then the specification of the measurement data as the eliminating target is received. Alternatively, the measurement result may be displayed every time one measurement is terminated so as to select each time whether or not to select the result as the eliminating target.
The number of continuous measurements is set to a predetermined number of times but may be set and changed by the user (medical staff). Further, all measurement values corresponding to the specified person to be measured (patient ID) may be set as the targets regardless of whether or not the continuous measurement function is provided.
It is assumed to be used by a plurality of people to be measured in the present embodiment, but use may be made only by one person to be measured with such as a portable sphygmomanometer. In such a case, the most recent blood pressure values for a specified number of times (e.g., a predetermined number of times) out of the blood pressure values (measurement values) for a plurality of times measured in the past may simply be set as the targets.
Alternatively, the measurement values measured in a specific time band (morning time band, evening time band, etc.) or in a specific period (one day, one week, one month, etc.) may be set as the targets. The specific time band and the specific period may be respectively defined in advance or may be specified by the user. Further alternatively, input of measurement conditions may be received at the time of the measurement, and the information on the measurement conditions may also be included in the measurement result data. In this case, the measurement value in accordance with the measurement conditions specified by the user may be set as the target. The measurement conditions include at least one of the measuring place (e.g., office, home, etc.) and an administration result.
In the present embodiment, the average value is adopted for the statistical value, but may be a most frequent value, a maximum value, a minimum value, a deviation, a weighted average, or the like as long as it is a statistical value. A trend graph or a rate of change of the measurement values for a plurality of times may be calculated in addition to/in place of the statistical value of the measurement values for a plurality of times.
A variant of the first embodiment of the present invention will be described next. The specification control unit 104 further includes a reliability rate calculating portion 112 and an extracting portion 114.
The reliability rate calculating portion 112 calculates a reliability rate of each measurement value based on the measurement result data for N times. The extracting portion 114 extracts a measurement value as an eliminating candidate out of the measurement values for N times based on the reliability rate calculated by the reliability rate calculating portion 112.
With reference to
In step S300, the reliability rate calculating portion 112 calculates a reliability rate of the blood pressure values for N times. A correction rate in a case where a median process or the like is performed on pulse wave amplitude value series (pulse wave amplitude values for a plurality of beats) to smoothen the same may be used for the calculation of the reliability rate. Specifically, the calculation can be made as “reliability rate (%)=100−correction rate”. The calculation of the correction rate is conventionally carried out as described in Japanese Unexamined Patent Publication No. H07-236617. The method of calculating the reliability rate is not particularly limited and any method other than the above may be used.
In step S302, the extracting portion 114 extracts the blood pressure value as the eliminating candidate out of the N blood pressure values based on the reliability rate calculated in step S300. Specifically, for instance, the blood pressure value of which reliability rate is smaller than a specific value is determined as the eliminating candidate. The specific value in this case may be a predetermined value (e.g., 80%) or may be a value set by the user.
In step S202A, the measurement data on the blood pressure value extracted as the eliminating candidate in step S302 is displayed so as to be identifiable from other measurement data. An example of a display screen is shown in
With reference to
The eliminating candidate is extracted and the measurement data set to the eliminating candidate is displayed so as to be identifiable from other measurement data, but in addition to/in place thereof, the reliability rates for respective measurement values calculated in step S300 may be displayed in association with the measurement values.
In the first embodiment and the variant thereof, the biological information display device performs both the measurement of the biological information (e.g., blood pressure) and the statistical process (calculation and display of statistical values). In a second embodiment of the present invention, on the other hand, the respective processes are executed in different devices.
The biological information is assumed to be the blood pressure in the present embodiment as well, and only the portions different from those of the first embodiment will be described below.
