Description

  The present invention relates to a blood pressure information measuring device having a cuff structure for accurately detecting information obtained from an artery.

  Conventionally, as a device for determining the degree of arteriosclerosis, there is a method of examining a pulse wave velocity (PWV: Pulse Wave Velocity) propelled from the heart.

  For example, Japanese Patent Application Laid-Open No. 2000-316821 (Patent Document 1) measures the lower limb upper limb blood pressure index (the ratio of the blood pressure value in the upper arm to the blood pressure value in the ankle or the ratio of the blood pressure value in the ankle to the blood pressure value in the upper arm). For the lower limb upper limb blood pressure index measuring device (paragraph 0001).

  Japanese Patent Laid-Open No. 2007-44362 (Patent Document 2) relates to “a blood pressure pulse wave inspection cuff used for measuring blood pressure and the like, and in particular, propagation of blood pressure and a pulse wave serving as an index of blood vessel wall hardness. A technique related to a “cuff capable of measuring both speeds” is disclosed (paragraph 0001).

  Japanese Patent Laid-Open No. 2000-79101 (Patent Document 3) discloses a technique relating to “a blood pressure meter that measures blood pressure based on a change in arterial wall vibration accompanying a change in cuff pressure, and particularly a cuff band structure of the blood pressure meter”. Disclosed (paragraph 0001).

  Japanese Patent Application Laid-Open No. 2004-254717 (Patent Document 4) discloses a technique relating to “a cuff band provided with an air bag for artery compression in a sphygmomanometer that measures biological information such as blood pressure and pulse wave, and a sphygmomanometer using the cuff band”. Disclosed (paragraph 0001).

  Japanese Patent Laying-Open No. 2006-334153 (Patent Document 5) discloses a technique relating to “blood pressure measuring device, more specifically, improvement of an oscillometric blood pressure measuring device” (paragraph 0001).

Further, it is generally known that among the arteries passing through the human arm, the brachial artery and the brachial deep artery are dissociated from the base of the arm toward the elbow (see, for example, Non-Patent Document 1).

  PWV wears cuffs that measure pulse waves in at least two places, such as the upper arm and lower limbs, and simultaneously measures the pulse waves, thereby wearing cuffs that measure the difference in the appearance time of each pulse wave and pulse waves. It is calculated from the length of the artery between the two points. For this reason, it is necessary to attach cuffs or the like to at least two places, and it is difficult to easily measure PWV at home.

  Further, according to the technique disclosed in Japanese Patent Application Laid-Open No. 2007-44362, when the pulse rate and blood pressure are measured with the above-mentioned cuff, in the upper arm part, the upper part (heart side) and the lower part (peripheral (wrist) side) Arterial location is different. For this reason, when used on subjects with different arm circumferences, there is a possibility that the compression force and compression range necessary for measuring the pulse wave and blood pressure cannot be secured. For example, a range of “insufficient compression force” may occur for a measurer who has an arm corresponding to the upper limit of the setting target arm circumference. Furthermore, since the reflection from the periphery is superimposed only on the pulse wave measurement cuff, there is a possibility that the reflected wave cannot be correctly separated.

  According to the technique disclosed in Japanese Patent Application Laid-Open No. 2000-79101, the pressure on the artery is not uniformly performed, and therefore the measurement air bag must be arranged at the center of the cuff. Moreover, the air bag for compression is also an integral structure. For this reason, when measuring pulse waves, it is impossible to achieve both pulse measurement and blood pumping (cannot completely occlude the artery), and it is structurally impossible to suppress superposition of reflection from the periphery completely. There's a problem.

  According to the technique disclosed in Japanese Patent Application Laid-Open No. 2004-254717, since the pressure cuff and the measurement cuff communicate with each other, there is a problem that pulsation is transmitted to the measurement cuff via the pressure cuff. In addition, since the pressure cuff and the measurement cuff communicate with each other, the above-described structure in which the capacity of the cuff is increased absorbs the pulse wave vibration. As a result, accurate measurement of information such as pulse wave amplitude has been difficult.

  In addition, since the arterial position is different between the upper part and the lower part of the upper arm, it is difficult for a measurer to ensure the compression force. Further, since a cuff capable of driving blood is not provided only on the peripheral side, there is a problem that superposition of reflection from the periphery cannot be suppressed.

  According to the technique disclosed in Japanese Patent Application Laid-Open No. 2006-334153, as described above, since the arterial position in the upper arm is different, it is difficult to ensure the compression force for the measurers having different arm circumferences. there were.

  In addition, considering the positional relationship between the brachial artery and the brachial deep artery of the human body, the existing cuff band does not accurately apply the compression force to each artery, and as a result, the accuracy of the measurement result may be reduced.

  The present invention has been made to solve the above-described problems, and its purpose is to ensure a compression force and a compression range necessary for measurement, and to provide a wide measurement range and an accurate pulse wave. It is to provide a cuff band that can be detected.

  Another object is to provide a blood pressure information measuring device capable of reliably ensuring a compression force and a compression range necessary for measurement and detecting a wide measurement range and an accurate pulse wave.

  A cuff band of a blood pressure information measuring device according to an aspect of the present invention includes a blood cuff for crushing and a pulse cuff for measuring a pulse wave. The tourniquet cuff and the pulse wave cuff are arranged along the central axis direction of the cuff belt winding. The partial region of the blood cuff and the partial region of the pulse wave cuff are arranged in parallel along the winding direction of the cuff band.

  Preferably, the cuff band further includes a cuff configured to wrap the pulse wave cuff and the tourniquet cuff.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same parts are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed description thereof will not be repeated.

  Further, in the case where different embodiments are described, the description of the configuration according to the embodiment will not be repeated except for the configuration unique to the embodiment.

<First Embodiment>
First, the blood pressure information measuring device according to the first embodiment of the present invention will be described.

[Hardware configuration]
With reference to FIG. 1, the structure of the blood-pressure information measuring apparatus 1 which concerns on embodiment of this invention is demonstrated. FIG. 1 is a block diagram illustrating a hardware configuration of the blood pressure information measurement device 1. The blood pressure information measuring device 1 includes a cuff belt 11, an electromagnetic valve drive circuit 21, an exhaust valve drive circuit 23, an air pump drive circuit 25, an air pump 27, electromagnetic valves 31, 33, an exhaust valve 35, and a pressure sensor. 41, an amplifier 43, an A / D (Analog to Digital) converter 45, a CPU (Central Processing Unit) 100, an operation switch 110, a monitor 120, and a memory 130.

  The cuff band 11 includes a tourniquet cuff 13 and a pulse wave cuff 15. The position where the pulse cuff 15 is arranged is preferably a position rotated from the center of the blood cuff 13 by about 60 ° in the arm circumferential direction with respect to the target arm circumference. The distance 100 between the center line of the blood cuff 13 and the center line of the pulse wave cuff 15 is preferably larger than, for example, the distance between two arteries of the living body. Considering individual differences between living bodies, the interval 100 is preferably larger than the interval between the arteries of a large living body. When a plurality of cuff bands 11 are prepared according to the classification of the size of the living body, the interval 100 may be defined according to the upper limit value of each size.

  In addition, each length of the winding direction of the blood cuff 13 and the pulse wave cuff 15 may be shorter than a standard arm circumference of a living body assumed as a usage target of the blood pressure information measurement device 1. When the blood cuff 13 and the pulse wave cuff 15 are wound around the living body, both ends of each cuff are difficult to overlap each other, so that each cuff is not sufficiently wound around the overlapping portion, or due to insufficient compression force. Measurement deficiencies can be prevented. As a result, the compression efficiency to the blood vessels and the accuracy of detecting the pulse are increased.

  The cuff belt 11 is prepared in advance in a plurality of sizes assuming a plurality of physiques of the user. For example, “S size” is defined on the assumption that the corresponding arm circumference is 17 to 22 cm. In this case, the size of the blood cuff 13 is, for example, 90 mm (arm length direction) × 160 mm (arm circumferential direction).

  “M size” is defined assuming a corresponding arm circumference of 22 to 32 cm. In this case, the size of the blood cuff 13 is, for example, 125 mm (arm length direction) × 220 mm (arm circumferential direction).

  “L size” is defined assuming a corresponding arm circumference of 32 to 42 cm. In this case, the size of the blood cuff 13 is, for example, 150 mm (arm length direction) × 300 mm (arm circumferential direction).

  The size of the blood cuff 13 is based on the provisions of JIS (Japan Industrial Standard) T1115, Section 5.4, “cuff and bladder”. JIST1155 stipulates as follows: The optimum size of the cuff bladder (airbag) wrapped around the upper arm is the center of the cuff's applicable arm circumference and the width of the bladder is 40% of the arm circumference. Is 80%, preferably 100% of the arm circumference. The use of cuffs that are inappropriately sized for the arm circumference of the subject may affect the accuracy of the measurement.

  The definition of the length of the blood cuff 13 is based on the following known idea. If the cuff length (arm length direction) is too narrow relative to the upper arm, the blood pressure value is overestimated. That is, a “small cuff effect” in which the maximum blood pressure value is calculated to be high occurs. When the ratio (W / D) of the length W (arm length direction) of the tourniquet cuff and the upper arm diameter D (diameter) is 1.2 or less, the cuff pressure is not effectively transmitted to the blood vessel.

  In one aspect, the blood cuff 13 and the pulse wave cuff 15 are arranged along the central axis direction of the cuff belt winding. The partial region of the blood cuff 13 and the partial region of the pulse wave cuff 15 are arranged in parallel along the winding direction (arm circumferential direction) of the cuff band 11.

  Preferably, the length of the partial region of the blood cuff 13 in the winding direction is half or more than the length of the entire region of the blood cuff 13 in the winding direction. Preferably, the length in the winding direction of a part of the region of the pulse wave cuff 15 is half or more than the length of the entire region of the pulse wave cuff 15 in the winding direction.

  Preferably, one of both ends of the pulse wave cuff 15 along the central axis direction is located between both ends of the blood cuff 13 along the central axis direction. Preferably, one of both ends of the blood cuff 13 along the central axis direction is located between both ends of the pulse wave cuff 15 along the central axis direction.

  Referring back to FIG. 1, the operation switch 110 receives an instruction input to the blood pressure information measurement device 1. The monitor 120 displays the state of the blood pressure information measurement device 1. For example, the monitor 120 displays the current state of the blood pressure information measurement device 1, the measured blood pressure information, the user identification name registered in the past, the measurement time, the winding state of the cuff belt 11, and the like.

  The CPU 100 controls the operation of the blood pressure information measurement device 1. Specifically, the CPU 100 sends a command for switching opening and closing of the electromagnetic valves 31 and 33 to the electromagnetic valve drive circuit 21. In response to a command from the CPU 100, the solenoid valve drive circuit 21 causes the solenoid valve 31 to perform an opening operation or a closing operation.

  The CPU 100 sends a command for switching the opening and closing of the exhaust valve 35 to the exhaust valve drive circuit 23. The CPU 100 sends an instruction to drive or stop the air pump 27 to the air pump drive circuit 25. When the air pump 27 is driven, the compressed air is supplied to the blood cuff 13 and the pulse wave cuff 15 via the electromagnetic valves 31 and 35.

  The pressure sensor 41 detects the pressure of the air supplied to the blood cuff 13 and the pulse wave cuff 15 and outputs a detection signal. The detection signal is input to the amplifier 43.

  The amplifier 43 amplifies the signal and outputs the amplified signal. The output signal is input to the A / D converter 45 as an analog signal. The A / D converter 45 converts the input analog signal into digital data, and sends the digital data to the CPU 100. The CPU 100 detects the internal pressure in the blood cuff 13 and the pulse wave cuff 15 based on the digital data, and controls the operation of the air pump 27 according to the detection result. The signal for control is supplied to the air pump drive circuit 25 as described above.

  The memory 130 stores data and software prepared in advance when the blood pressure information measuring device 1 is manufactured, data generated by the CPU 100 when the blood pressure information measuring device 1 is operated, or data given by the user of the blood pressure information measuring device 1. Storing. The memory 130 is realized as at least a nonvolatile memory. A random access memory capable of high-speed access may be further used for temporary data storage. In still another aspect, the blood pressure information measurement device 1 may include a card reader for driving a memory card or other removable recording medium, or a USB or other data communication interface.

  The blood cuff 13 and the pulse wave cuff 15 are configured as air bags. The blood cuff 13 and the pulse wave cuff 15 have a shape close to a rectangle, for example. As is clear from FIG. 1, both end portions of the blood cuff 13 and the both end portions of the pulse wave cuff 15 do not have to coincide with each other. One end portion in the longitudinal direction of the blood cuff 13 (on the right side in FIG. 1) is attached to the cuff band 11 so as to be positioned outside one end portion in the longitudinal direction of the pulse wave cuff 15. Further, the other end portion (left side in FIG. 1) of the blood cuff 13 in the longitudinal direction is attached to the cuff band 11 so as to be located on the right side of the other end portion of the pulse wave cuff 15. Specifically, it is preferable that the length of the overlapping region of the pulse wave cuff 15 and the blood cuff 13 is about half of the circumference of the standard upper arm of an adult. In general, one of two arteries for measuring blood pressure information using the upper arm is formed in the upper arm so as to gradually move away from other blood vessels in a spiral manner with the humerus as an axis. According to the configuration of the cuff band 11 according to the present embodiment, the tourniquet cuff 13 and the pulse wave cuff 15 are arranged so as to compress the two arteries as long as it is at least about half the length around the upper arm. Because.

  With reference to FIG. 2, the usage mode of the cuff belt 11 according to the embodiment of the present invention will be described. FIG. 2 is a diagram illustrating a state in which the cuff belt 11 is attached to the left arm 200 of the user who is the measurement subject.

  When measuring blood pressure information, the cuff band 11 is wound around the left arm 200 so that the pulse wave cuff 15 is positioned close to the shoulder. At this time, both the pulse wave cuff 15 and the blood cuff 13 are wound around the left arm 200 so as to apply a compression force to each blood vessel.

  With reference to FIG. 3, the state in which the blood cuff 13 is wound around the arm will be further described. FIG. 3 is a cross-sectional view of the blood cuff 13 from the direction AA shown in FIG. The blood cuff 13 is disposed between the armband outer cloth 310 and the armband inner cloth 320. The tourniquet cuff 13 is not necessarily required to have a length enough to cover the entire circumference of the arm, as long as it can transmit the compression force necessary to drive the artery. Conversely, it is preferable that both ends of the blood cuff 13 do not overlap when wound around the arm. This is because the overlapping portion of the blood cuff 13 may prevent the blood vessel waveform sound from being accurately measured.

  With reference to FIG. 4, the state in which the blood cuff 13 is wound around the arm will be further described. 4 is a cross-sectional view showing the pulse wave cuff 15 from the direction BB shown in FIG. The pulse wave cuff 15 is disposed between the armband outer cloth 310 and the armband inner cloth 320. The pulse wave cuff 15 is not necessarily required to be long enough to cover the entire circumference of the arm, as long as the artery crushed by the blood cuff 13 can be compressed. Conversely, it is preferable that both ends of the pulse wave cuff 15 do not overlap when wrapped around the arm. This is because the waveform of the blood vessel cannot be accurately measured due to the overlapping portion of the pulse wave cuff 15.

  With reference to FIGS. 3 and 4, the positions of both ends of the blood cuff 13 and the positions of both ends of the pulse wave cuff 15 when the cuff band 11 is wound around the arm of the measurer are not necessarily limited. It does not have to match. Since both the blood cuff 13 and the pulse wave cuff 15 need only compress the same artery necessary for pulse wave and blood pressure measurement, the blood cuff 13 and the pulse wave cuff 15 are surely compressed. For example, the overlapping portion may be about 50 to 80% of the standard adult arm circumference. With such a configuration of overlapping portions, when the tourniquet cuff 13 is placed at a position that correctly presses the blood vessel, the pulse wave cuff 15 is also located at a location that correctly presses another blood vessel.

[Function configuration]
With reference to FIG. 5, CPU 100 that realizes blood pressure information measurement apparatus 1 according to the embodiment of the present invention will be described. FIG. 5 is a block diagram showing a configuration of functions executed by CPU 100. The CPU 100 includes a pump drive control unit 510, an electromagnetic valve opening / closing control unit 520, an exhaust valve opening / closing control unit 530, a calculation unit 540, a display control unit 550, and a data management unit 560. These functions are realized by the CPU 100 executing software configured to execute the functions.

  The pump drive control unit 510 sends a signal for controlling operation, stop, and other operations of the air pump 27 to the air pump drive circuit 25. The electromagnetic valve opening / closing control unit 520 sends a signal for controlling the opening / closing of the electromagnetic valves 31 and 33 to the electromagnetic valve drive circuit 21. The exhaust valve drive circuit 530 sends a signal for controlling the opening and closing of the exhaust valve 35 to the exhaust valve drive circuit 23. The calculation unit 540 calculates blood pressure information (blood pressure value, pulse rate, etc.) based on the signal from the A / D converter 45. The display control unit 550 displays the blood pressure information on the monitor 120. The data management unit 560 writes the data calculated by the calculation unit 540 into the memory 130. In addition, the data management unit 560 reads data stored in the memory 130 in response to a read command for the blood pressure information measurement device 1. The display control unit 550 causes the monitor 120 to display the read data.

[Control structure]
With reference to FIG. 6, the control structure of the blood pressure information measurement device 1 according to the embodiment of the present invention will be described. FIG. 6 is a flowchart showing a part of a series of operations executed by CPU 100 to pressurize the cuff and measure the pulse wave. In the following flowcharts, the same process is denoted by the same step number. Therefore, description of these processes will not be repeated.

  In step S610, the CPU 100 causes the exhaust valve drive circuit 23 to close the exhaust valve 35. The CPU 100 sends a command to open the electromagnetic valve 33 that controls the supply of air to the blood cuff 13 for measuring blood pressure to the electromagnetic valve drive circuit 21. The solenoid valve drive circuit 21 opens the solenoid valve 33 in response to the command. The CPU 100 sends a command to close the control valve 31 that controls the supply of air to the pulse wave cuff 15 to the electromagnetic valve drive circuit 21. The solenoid valve drive circuit 21 closes the solenoid valve 31 in response to the command.

  In step S615, the CPU 100 sends a command to operate the air pump 27 to the air pump drive circuit 25. The air pump 25 starts the operation of the air pump 27 in response to the command. The compressed air is output from the air pump 25. Since the electromagnetic valve 31 is closed and the electromagnetic valve 33 is opened, the compressed air is supplied to the inside of the blood cuff 13.

In step S620, CPU 100 starts blood pressure measurement (pressure measurement).
In step S625, CPU 100 determines whether blood pressure measurement is completed based on the output from A / D converter 45. When CPU 100 determines that blood pressure measurement has been completed (YES in step S625), CPU 100 switches the process to step S630. If not (NO in step S625), CPU 100 returns the process to step S615. The air pump 27 continues to pressurize.

  In step S630, CPU 100 stops the operation of air pump 27. In step S635, the CPU 10 closes the electromagnetic valve 33. The compressed air supplied to the blood cuff 13 is maintained. In step S640, CPU 100 gives a command to solenoid valve drive circuit 21 to open solenoid valve 31. A compressed air supply path from the air pump 27 to the pulse wave cuff 15 is formed.

  In step S645, CPU 100 operates air pump 27. Compressed air is supplied from the air pump 27 to the pulse wave cuff 15 via the electromagnetic valve 31. In step S650, CPU 100 determines whether the internal pressure value of pulse wave cuff 15 has reached a preset pressure value based on the output from A / D converter 45 or not. The preset pressure value is about 100 mmHg, for example. When CPU 100 determines that the internal pressure value has reached a preset pressure value (YES in step S650), CPU 100 switches control to step S655. If not (NO in step S650), CPU 100 returns control to step S645 and continues the operation of air pump 27.

  In step S <b> 655, CPU 100 measures the pulse wave based on the measurement value from pulse wave cuff 15. In step S660, CPU 100 performs correlation comparison of pulse waves. Specifically, the CPU 100 determines whether the pulse wave cuff 15 needs to be pressurized / depressurized. When CPU 100 determines that adjustment of pulse wave cuff 15 is not necessary, CPU 100 switches control to step S685. When CPU 100 determines that pressurization of pulse wave cuff 15 is necessary, CPU 100 switches control to step S665. When CPU 100 determines that pressure reduction of pulse wave cuff 15 is necessary, CPU 100 switches control to step S670. When the blood pressure information measurement apparatus 1 performs pressurization measurement, since the pulse wave cuff 15 is in a blood-feeding state, it is not necessary to determine whether the blood-feeding is sufficient or insufficient.

  In step S665, the CPU 100 operates the air pump 27. Since the compressed air is supplied from the air pump to the pulse wave cuff 15 via the electromagnetic valve 31, the internal pressure of the pulse wave cuff 15 increases. Thereafter, the CPU 100 returns the control to step S655.

  In step S670, CPU 100 sends an instruction to open exhaust valve 23 to exhaust valve drive circuit 23. When the exhaust valve drive circuit 23 opens the exhaust valve 23 in response to the command, the compressed air flows out from the pulse wave cuff 15. As a result, the internal pressure of the pulse wave cuff 15 decreases.

  In step S675, CPU 100 determines whether or not the internal pressure of pulse wave cuff 15 has reached a preset pressure value based on the signal from A / D converter 45. When CPU 100 determines that the internal pressure has reached a preset pressure value (YES in step S675), CPU 100 switches control to step S680. If not (NO in step S675), CPU 100 returns control to step S670.

  In step S680, CPU 100 sends a command to close exhaust valve 35 to exhaust valve drive circuit 23. The exhaust valve drive circuit 23 closes the exhaust valve 35 in response to the command. Thereby, the internal pressure of the pulse wave cuff 15 is kept constant. Thereafter, the CPU 100 returns the control to step S655.

  In step S685, the CPU 100 opens all the solenoid valves 31, 33 and the exhaust valve 35. The compressed air inside the pulse wave cuff 15 and the blood cuff 13 is released to the outside.

  In step S690, CPU 100 displays the measurement result (blood pressure value, pulse rate, measurement date and time) on monitor 120.

[effect]
As described above, the blood pressure information measuring device 1 according to the present embodiment has a blood pressure obtained by rotating and arranging the pulse cuff 15 provided on the upstream side (heart side) in the arm circumferential direction with respect to the blood cuff 13. / Has a cuff structure (cuff belt 11) for pulse group measurement. After the pulse wave cuff 15 and the blood cuff 13 are wound around the living body, the blood pressure information measurement device 1 applies pressure to the blood cuff 13 and inflates the air bag of the blood cuff 13. The blood pressure information measuring device 1 measures the blood pressure by applying pressure (expanding) to the pulse cuff 15 in a state where the blood cuffing state by the blood cuff 13 is maintained after measuring the blood pressure by pressurization measurement. .

  The blood pressure information measuring apparatus 1 can shift to pulse wave measurement in a blood-pulsation state by applying pressure only to the pulse wave cuff 15 for reduced pressure measurement by performing pulse wave measurement after measuring blood pressure by pressurization. Thereby, the whole measurement time can be shortened.

  Further, as shown in the configuration of the cuff band 11, the pulse wave cuff 15 is rotated inward of the body (arm circumferential direction) with respect to the blood cuff 13 in accordance with the blood vessel (artery) position on the upper arm of the living body. By arranging them, the pulsation cuff 15 can secure the compression force and the compression range. Thereby, accurate pulse group information can be acquired.

  In addition, when the pressure on the artery is insufficient, the amplitude of the waveform becomes small and it is difficult to accurately detect the pulse wave. However, the blood pressure information measurement device 1 according to the present embodiment is Since the configuration is such that the pulse wave is measured after the blood pressure measurement by the pressure measurement, the pulse group measurement can be surely performed in the state of blood driving.

<Modification>
Hereinafter, modifications of the first embodiment will be described. Note that the hardware of the blood pressure information measurement device according to the present modification is the same as the hardware configuration of the blood pressure information measurement device 1 according to the first embodiment. Therefore, the description of hardware will not be repeated. Hereinafter, the blood pressure information measuring device according to the present modification will be described using the configuration of the blood pressure information measuring device 1 according to the first embodiment.

  In the blood pressure information measurement device 1 according to the present modification, in the configuration according to the first embodiment, after the cuff band 11 is wound around the living body, the pulse cuff 15 and the blood cuff 13 are driven (about 200 mmHg). Apply pressure up to. Thereafter, the blood pressure information measurement device 1 measures the pulse group after reducing the pulse wave cuff 15 to a pressure (about 100 mmHg) necessary for measuring the pulse wave. Thereafter, the blood pressure information measuring device 1 releases the pressure of the pulse wave cuff 15 and then gradually reduces the internal pressure of the blood cuff 13 in the state of blood pumping to measure the blood pressure (decompression measurement).

[When measuring pulse wave]
With reference to FIG. 7, a control structure of blood pressure information measurement device 1 according to a modification of the present embodiment will be described. FIG. 7 is a flowchart showing a part of a series of operations executed by CPU 100 of blood pressure information measurement device 1 according to this modification. The same steps as those described above are given the same step numbers. Therefore, the description of the same process will not be repeated.

  In step S705, the CPU 100 closes the exhaust valve 35 and opens the electromagnetic valve 33 of the blood pressure cuff (the blood cuff 13) and the electromagnetic valve 31 of the pulse wave cuff 15.

  In step S710, CPU 100 pressurizes blood cuff 13 by driving air pump 27 until the internal pressure of blood pressure cuff reaches a preset pressure value (for example, about 200 mmHg).

  In step S715, the CPU 100 opens the exhaust valve 35. In step S720, CPU 100 closes exhaust valve 35.

  In step S725, CPU 100 performs correlation comparison of pulse waves. Specifically, the CPU 100 determines whether or not it is necessary to pressurize / depressurize the pulse wave cuff 15 or pressurize the blood cuff 13. This determination is made based on, for example, whether or not the internal pressures of the pulse wave cuff 15 and the blood cuff 13 have reached a preset pressure range. If CPU 100 determines that adjustment of pulse wave cuff 15 and blood cuff 13 is not required, control is switched to step S730. When CPU 100 determines that pressurization of tourniquet cuff 13 is necessary, CPU 100 switches control to step S730. When CPU 100 determines that pressure reduction of pulse wave cuff 15 is necessary, CPU 100 switches control to step S670.

  In step S730, the CPU 100 closes the electromagnetic valve 31 of the pulse wave cuff 15, opens the electromagnetic valve 33 of the blood cuff 13, and operates the air pump 27. In this case, the CPU 100 gives a command to the air pump drive circuit 25 so that, for example, the pressure of about 30 mmHg is increased in order to eliminate the lack of blood drive in the blood drive cuff 13.

  In step S735, the CPU 100 closes the electromagnetic valve 33 of the blood cuff 13 and opens the electromagnetic valve 31 of the pulse wave cuff 15.

  In step S740, CPU 100 opens exhaust valve 35. In this case, the CPU 100 opens the exhaust valve 35 until the internal pressure of the pulse wave cuff 15 becomes 0 mmHg.

  In step S745, CPU 100 closes electromagnetic valve 31 and exhaust valve 35 of pulse wave cuff 15.

  In step S 750, CPU 100 opens electromagnetic valve 33 of blood cuff 13. In step S755, the CPU 100 controls the opening and closing of the exhaust valve 35 to reduce the internal pressure of the blood cuff 13 at a constant speed.

  In step S760, CPU 100 measures the blood pressure based on the output from A / D converter 45 (decompression measurement).

  In step S765, CPU 100 determines whether measurement of blood pressure has been completed. This determination is made based on, for example, whether or not the time elapsed since the start of blood pressure measurement has exceeded a predetermined time. When CPU 100 determines that the measurement of blood pressure has been completed (YES in step S765), CPU 100 switches control to step S770. If not (NO in step S765), CPU 100 returns the control to step S760.

  In step S770, the CPU 100 opens the electromagnetic valve 33 of the blood cuff 13 and quickly exhausts it.

[effect]
The blood pressure information measurement device 1 according to this modification performs blood pressure measurement after performing pulse group measurement. By measuring in this order, the blood pressure information measuring device 1 can shift to blood pressure measurement while maintaining the blood-feeding state at the time of pulse group measurement, and therefore the overall measurement time can be shortened.

[Waveform]
Here, waveforms that can be detected by the blood pressure information measurement device 1 according to the present embodiment will be described with reference to FIGS. 8 and 9. FIG. 8A shows a waveform detected in a state where adjustment is not necessary. FIG. 8B is a diagram illustrating a waveform detected in a state where decompression is necessary. FIG. 8C is a diagram illustrating a waveform detected in a state where pressurization is necessary.

  Referring to FIG. 8A, since the waveform 810 has almost no deformation in its shape, feature points can be easily extracted. Referring to FIG. 8B, the waveform 820 is crushed at the bottom. For this reason, the characteristic points of the waveform 820 have disappeared. Referring to FIG. 8C, the amplitude of waveform 830 is smaller than the amplitudes of waveforms 810 and 820. Therefore, it becomes difficult to extract feature points of the waveform 830.

  FIG. 9 is a diagram for explaining a criterion for determining whether or not the blood cuffing by the blood cuff 13 is sufficient or insufficient.

  A waveform 910 shows a waveform in the case where sufficient blood driving is performed. A waveform 920 shows a waveform in the case where the tourniquet is insufficient. That is, the peak portions of the portions 930 and 940 of the waveform 920 are unclear due to the influence of reflection from the peripheral side. Therefore, when the feature points cannot be extracted, the feature points of the waveform are clarified and extracted by pressurizing the blood cuff 13 to drive the blood flow and remove the influence of reflection from the peripheral side. Can do.

  The determination of whether or not the blood drive is sufficient is performed, for example, as follows. First, the CPU 100 performs correlation comparison of the waveforms 910 and 920 shown in FIG. Specifically, the CPU 100 compares feature points. As described above, when the blood drive is insufficient, the peak portion becomes unclear due to the influence of reflection. Therefore, the CPU 100 determines such a case as a case where the blood drive is insufficient. In this case, the CPU 100 pressurizes the tourniquet cuff 13 by about 30 mmHg, compares the pulse wave waveforms before and after the pressurization, and determines that the tourniquet is sufficient when there is no change in the waveform.

[Configuration of cuff belt]
The configuration of the cuff strip 1000 will be described with reference to FIG. FIG. 11 is a diagram showing a cross section of a cuff strip 1000 according to the second embodiment of the present invention. The cuff strip 1000 is configured such that when it is wound around the arm 200 of the measurer, the winding cuff 16 is positioned outside.

  The cuff band 1100 includes a curler 1120 between the winding cuff 16 and the pulse wave cuff 15. The curler 1120 assists in winding the pulse wave cuff 15. The cuff belt 1100 includes a curler 1130 between the winding cuff 16 and the blood cuff 13. The curler 1130 assists in winding the blood cuff 13.

  By the winding cuff 16 and the curlers 1120 and 1130, the pulse wave cuff 15 and the blood cuff 13 are securely wound around the upper arm of the measurer. Thus, the pulse wave cuff 15 and the blood cuff 13 are sufficiently compressed, and the measurement result is hardly affected by the reflected wave.

  With reference to FIGS. 12 and 13, the cross-sectional structure of cuff strip 1100 according to the present embodiment will be further described. FIG. 12 is a diagram illustrating a state in which the cuff band 1100 is cut along a line XX. The cuff belt 1100 includes a tourniquet cuff 13, a winding cuff 16, a housing 1110, a curler 1130, and a cushioning material 1140. The blood cuff 13 is disposed between the curler 1130 and the cushioning material 1140. The cushioning material 1140 blocks vibration from the upper arm of the measurer. The buffer material 1140 is made of resin, for example.

  FIG. 13 is a diagram illustrating a state in which the cuff strip 1100 is cut along a line YY.

[Control structure]
With reference to FIG. 14, the control structure of the blood pressure information measurement device 2 according to the second embodiment of the present invention will be described. FIG. 14 is a flowchart showing a part of a series of operations executed by CPU 100 that implements blood pressure information measurement device 2.

When CPU 100 determines that the internal pressure of winding cuff 16 has reached a preset value (YES in step S1420), CPU 100 switches control to step S1425. If not (NO in step S), CPU 100 returns control to step S1415.

  In step S 1430, CPU 100 closes exhaust valve 36, opens electromagnetic valve 33 of blood cuff 13, and closes electromagnetic valve 31 of pulse wave cuff 15.

  In step S1440, CPU 100 determines whether or not the capacity (internal pressure) of pulse wave cuff 15 needs to be adjusted based on a preset pressure value and an output value from A / D converter 46. When CPU 100 determines that adjustment is necessary (YES in step S1440), CPU 100 switches control to step S1445. If not (NO in step S1440), CPU 100 switches control to step S1480.

  In step S1445, CPU 100 sends a command for operating air pump 28 to air pump drive circuit 26. The air pump drive circuit 26 operates the air pump 28 in response to the command. The air pump 28 supplies compressed air to the winding cuff 16 again.

  In step S1450, CPU 100 determines whether or not the internal pressure of pulse wave cuff 15 has increased by ΔP (for example, about 10 mmHg) based on the output from A / D converter 46. When CPU 100 determines that the internal pressure has increased by ΔP (YES in step S1450), CPU 100 switches control to step S1455. If not (NO in step S1450), CPU 100 switches control to step S1445.

  In step S 1455, CPU 100 sends a command to stop operation of air pump 28 to air pump drive circuit 26. The air pump drive circuit 26 stops the air pump 28 in response to the command. The supply of compressed air to the winding cuff 16 ends.

[effect]
As described above, the blood pressure information measuring device 2 according to the second embodiment of the present invention includes the cuff band 1000 having a so-called spot arm type structure. In such a structure, for example, when the blood cuff 13 is compatible with both arms, the wrapping cuff 16 is used in common and the inner cuff structure is used for pulse wave measurement and blood pressure measurement (drive (For blood) to be placed independently. Similarly to the first embodiment, the blood pressure information measuring device 2 is arranged at a position where the pulse wave cuff 15 provided on the upstream side (heart side) is rotated about 180 ° with respect to the blood cuff 13. By doing this, the pulse wave can be measured to the same extent as the circumference of the target arm as in blood pressure measurement. Thereby, the measurement using both the left and right arms of the living body becomes possible.

  At that time, the cuff width (length in the arm direction) of the pulse cuff 15 is set to about 30% of the cuff width of the blood cuff 13 so that the waveform becomes dull due to an increase in the air capacity of the pulse cuff 15 (pulse accuracy) Can be avoided. If the waveform of the pulse wave cuff 15 is blunted (pulse wave cuff air volume: adjustment is required) (YES in step S1440), the blood pressure information measurement device 2 applies pressure to the winding cuff 16 to provide a blood cuff cuff. Press 13 from the outside. Thereby, the blood pressure information measuring device 2 increases the pressure of the blood cuff 13 by ΔP (mmHg) without increasing the air capacity of the blood cuff 13. In this state, the blood pressure information measurement device 2 reduces the internal pressure of the blood cuff 13 by ΔP (mmHg) while reducing the air amount of the blood cuff 13 by opening the exhaust valve 35 (internal pressure change amount = ΔP−ΔP). = 0 mmHg). As a result, the waveform dullness can be eliminated while the compression force is secured.

  Further, by inflating the blood cuff 13 simultaneously with the pressure application (expansion) of the pulse wave cuff 15, the influence of the reflection of the pulse wave from the peripheral side can be removed.

  Further, since the width of the winding cuff 16 in the arm direction is about the sum of the length of the pulse cuff 15 and the length of the blood cuff 13, when only the pulse cuff 15 is compressed, the inclination of the curlers 1120 and 1130 ( The one-pressed state of the winding cuff 16) may occur, and this may cause noise / non-uniform pressure.

  However, according to the blood pressure information measuring device 2 according to the present embodiment, the pressure force by the winding cuff 16 acts uniformly on the pulse cuff 15 and the blood cuff 16 so that the pressure balance is not lost and stable measurement is possible. It becomes.

  Further, the cuff band 1000 of the blood pressure information measuring device 2 adopts a spot arm type structure. Therefore, by controlling the operation of the winding cuff 16 and the operations of the pulse wave cuff 15 and the blood cuff 13 in a coordinated manner, each cuff included in the cuff band 1000 is lengthened (the air capacity is increased). On the other hand, the waveform dullness can be eliminated. As a result, both accurate measurement and enlargement of the target arm circumference can be achieved.

  In the pulse wave measurement, a configuration corresponding to both arms can be adopted as in the blood pressure measurement. Therefore, since the measurement flexibility is improved, the convenience for the user is enhanced.

<Modification>

The blood pressure information measurement device 2 according to this modification performs blood pressure measurement after applying pressure to the winding cuff 16, and in the case of “decompression measurement”, the blood pressure and pulse group are operated by the same operation as in the second embodiment. Is measured continuously.

Therefore, the description of the hardware configuration will not be repeated.

When the change amount of the internal pressure of the pulse wave cuff 15 is (ΔP−ΔP), the CPU 100 returns the target value of the internal pressure of the pulse wave cuff 15 to the pressure value stored in the memory 130.

  Referring to FIG. 16, in step S1530, CPU 100 opens exhaust valve 35 until the internal pressure of pulse wave cuff 15 reaches about 0 mmHg. In step S 1540, CPU 100 closes electromagnetic valve 31 and exhaust valve 35 of pulse wave cuff 15.

  In step S 1550, CPU 100 opens electromagnetic valve 33 of blood cuff 13. In step S1560, the CPU 100 controls the opening and closing of the exhaust valve 35 using the exhaust valve drive circuit 23, thereby reducing the internal pressure of the blood cuff 13 at a constant speed. In step S1570, CPU 100 measures blood pressure (decompression measurement).

  In step S1580, CPU 100 determines whether blood pressure measurement is completed. If CPU 100 determines that the measurement of blood pressure has been completed (YES in step S1580), CPU 100 switches control to step S1590. If not (NO in step S1580), CPU 100 switches control to step S1570.

  In step S 1590, CPU 100 opens electromagnetic valve 33 of blood cuff 13 and rapidly exhausts the compressed air filled in blood cuff 13.

In this case, the configuration is realized by, for example, Velcro (registered trademark) or other surface fastener. With such a configuration, the positional relationship between the blood cuff 13 and the pulse wave cuff 15 can be adjusted. Alternatively, as an alternative example of the configuration, the casing including the blood cuff 13 and the casing including the pulse wave cuff 15 may be separated. By configuring each housing to be rotatable, the positional relationship between the blood cuff 13 and the pulse wave cuff 15 can be easily set according to the user of the blood pressure information measurement device 1.
