Description

  The present invention relates to an electronic sphygmomanometer, and more particularly to an electronic sphygmomanometer having an arm insertion portion in which a cuff is disposed on an inner peripheral surface of a hollow opening portion into which an upper arm of a subject is inserted.

  Conventionally, an electronic sphygmomanometer using the upper arm cuff method is known and widely used. While blood pressure measurement by the upper arm cuff method is a very simple method, there are many factors that affect measurement accuracy. For this reason, various proposals have been made so far in order to improve the measurement accuracy.

  As an example of factors that affect measurement accuracy, for example, when measuring blood pressure, if the subject is leaning forward, the abdominal pressure increases and the abdominal artery is compressed, resulting in an increase in blood pressure. There are problems.

  On the other hand, for example, in Patent Document 1 below, the subject is in the correct posture regardless of the subject's physique (sitting height and arm length), the height of the desk on which the electronic sphygmomanometer is placed, and the like. There has been proposed an electronic sphygmomanometer in which an arm insertion portion for inserting an upper arm of a subject is configured to be rotatable so that blood pressure can be measured in a posture in which the back muscles are extended.

JP 2006-150143 A

  However, in the case of Patent Document 1, it is assumed that the electronic blood pressure monitor is placed at an appropriate distance from the subject. For this reason, when the electronic sphygmomanometer is placed at a position away from the subject, blood pressure cannot be measured in a correct posture. In this case, even if the subject tries to move the electronic sphygmomanometer to an appropriate position, the configuration is not easy to move, which is inconvenient for the subject.

  Further, in the case of Patent Document 1, even if the subject can move the electronic sphygmomanometer to an appropriate position, the forearm placement unit is fixed at a predetermined angle with respect to the desk. Therefore, the inserted arm of the subject is bent into a “<” shape as a whole, and the forearm comes close to the heart height when measuring blood pressure. When the forearm is placed in this manner, blood stasis is likely to occur, the generation timing of blood flow to the cuff peripheral portion may be unclear, and an error is included in the detection of systolic blood pressure.

  That is, in the case of the above-mentioned Patent Document 1, the work load in a series of operations performed by the subject to measure blood pressure in the correct posture is high, and new factors that affect the measurement accuracy are inherent.

  Details of the above problem will be described below with reference to FIG. FIG. 7 is a diagram illustrating the operation of the subject when blood pressure is measured using the electronic sphygmomanometer described in Patent Document 1, and the electronic sphygmomanometer is placed slightly away from the subject. FIG. 6 is a diagram illustrating an example of the operation of the subject for the subject to measure blood pressure in the correct posture.

  As shown in FIG. 7A, the subject 701 sitting in the correct posture, as shown in FIG. 7B, holds the arm insertion portion 711 with the left hand (the hand that does not measure blood pressure) during blood pressure measurement. The right arm is inserted into the arm insertion portion 711 by rotating in the direction of the arrow 721.

  At this time, the subject 701 is leaning forward as shown in FIG. 7C-1 and the abdominal pressure increases. That is, even if the arm insertion portion is configured to be rotatable as in Patent Document 1, if the electronic sphygmomanometer is not placed at an appropriate distance from the subject, the subject has a correct blood pressure. Measurement cannot be performed.

  At this time, as shown in FIG. 7C-2, the subject 701 can return to the correct posture by moving the electronic sphygmomanometer 710 to the subject 701 side. The examiner 701 needs to pull the pivotable (that is, unstable) arm insertion portion 711 upward (with the left hand) toward the front (in the direction of the arrow 722) while the upper arm of the right arm is inserted into the arm insertion portion 711. Yes, the work load for the subject 701 is high.

  Furthermore, as shown in FIG. 7C-2, even if the electronic sphygmomanometer 710 is moved to an appropriate position and returned to the correct posture, the forearm placement unit 712 of the electronic sphygmomanometer 710 On the other hand, since the arm of the subject 701 is bent into a “character shape” as a whole because the arm is arranged at a predetermined angle θ, the hand tip is brought close to the height position of the heart at the time of blood pressure measurement. Become.

  In such a state, although the influence of abdominal pressure can be eliminated, blood stasis is likely to occur, and when blood stasis occurs, the timing of blood flow to the cuff peripheral region is unclear, and systolic blood pressure is measured lower than actual May be.

  Thus, when the conventional electronic sphygmomanometer 710 is used, depending on the mounting position of the electronic sphygmomanometer, it is difficult to maintain a correct posture during blood pressure measurement, and the forearm cannot be mounted at an appropriate position. There is a problem.

  The present invention has been made in view of the above problems, and an electronic sphygmomanometer that allows a subject to easily maintain a correct posture during blood pressure measurement and can place a forearm at an appropriate position. The purpose is to provide.

In order to achieve the above object, an electronic blood pressure monitor according to the present invention has the following configuration. That is,
An electronic sphygmomanometer that measures blood pressure,
A first housing having a hollow opening into which the upper arm of the subject is inserted and having a cuff disposed on the inner peripheral surface;
A second housing that rotatably supports the first housing so that an elevation angle of the hollow opening can be changed;
The forearm of the subject is placed with the upper arm inserted into the hollow opening, and at least the first arm is rotated to a position substantially parallel to the placement surface of the electronic sphygmomanometer. A forearm mounting portion rotatably supported by the housing of
The second housing is characterized in that a sliding member is arranged so as to slide substantially parallel to the insertion direction of the upper arm with respect to the mounting surface of the electronic sphygmomanometer.

  According to the present invention, it is possible to provide an electronic sphygmomanometer in which a subject can easily maintain a correct posture and can place a forearm at an appropriate position during blood pressure measurement. .

It is a figure which shows an example of operation | movement of a subject in the case of measuring blood pressure using the conventional electronic blood pressure monitor.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

1. Configuration of Electronic Sphygmomanometer FIG. 1 is a diagram showing an external configuration of an electronic sphygmomanometer 100 according to the first embodiment of the present invention.

  As shown in FIG. 1, an electronic sphygmomanometer 100 includes an arm insertion portion 110 (first housing) for inserting the upper arm of a subject and a main body portion 120 (second housing) for supporting the arm insertion portion 110. And a forearm placement unit 130 on which the forearm of the subject is placed with the upper arm inserted into the arm insertion unit 110.

  In the arm insertion part 110, 112 is a hollow opening into which the upper arm of the subject is inserted. Reference numeral 111 denotes a cuff, which is disposed on the inner peripheral surface of the hollow opening 112. The cuff 111 compresses the blood vessel of the upper arm of the subject inserted into the hollow opening 112.

  Reference numeral 113 denotes a display unit that displays a blood pressure measurement result and the like. An operation unit 114 includes various switches 114 </ b> A to 114 </ b> C for operating the electronic blood pressure monitor 100. 114A is a start switch for instructing start of blood pressure measurement, and 114B is a stop switch for instructing stop of blood pressure measurement. Reference numeral 114C denotes a memory prohibition switch that prohibits storage of blood pressure measurement results in a storage unit (not shown).

  In the main body 120, reference numeral 121 denotes a rotation support unit that rotatably supports (axially supports) the arm insertion unit 110. Thereby, the elevation angle of the hollow opening 112 of the arm insertion portion 110 can be changed, and the subject can freely adjust the insertion angle of the upper arm.

  Reference numeral 122 denotes an arm insertion portion support portion. When the electronic sphygmomanometer 100 is not used, the arm insertion portion 110 is substantially parallel to the placement surface of the electronic sphygmomanometer 100 (the elevation angle of the hollow opening 112 is substantially zero degrees). The arm insertion part 110 is supported so that

  Note that the arm insertion portion support portion 122 has a contact surface with the arm insertion portion 110 made of a magnetic member, and is coupled to each other with the magnetic member 115 disposed on the contact surface on the arm insertion portion 110 side. . For this reason, when the electronic sphygmomanometer 100 is not used, the arm insertion portion 110 is fixed to the main body portion 120, and the rotation is restricted.

  When the electronic sphygmomanometer 100 is used, the upper arm of the subject is inserted into the arm insertion portion 110, and an upward force is applied to the arm insertion portion 110, so that the arm insertion portion support portion 122 is coupled. As a result, the arm insertion portion 110 rotates around the rotation support portion 121. As a result, the arm insertion part 110 is adjusted to an appropriate angle.

  Reference numeral 123 denotes a guide rib (sliding member) that allows the electronic sphygmomanometer 100 to easily slide in the direction of an arrow 140 (a direction substantially parallel to the insertion direction of the upper arm) with respect to the mounting surface of the electronic sphygmomanometer 100. In addition, two are provided substantially in parallel, and the lower surface thereof is constituted by a member having a low friction coefficient.

  Inside the main body 120, a pressurized air pump that sends pressurized air to the cuff 111, an exhaust valve that exhausts the air in the cuff 111 and adjusts the pressure of the cuff 111, and power to each part of the electronic sphygmomanometer 100 It is assumed that a power supply unit for supplying the power is incorporated.

  The cuff 111 has flexibility and is made of vinyl chloride, synthetic rubber, natural rubber, or the like that can expand and contract with pressure up to about 250 mmHg. In addition, a cuff ring 111a that covers the cuff 111 and is detachable from the hollow opening 112 into which the upper arm is inserted is provided. The cuff ring 111a protects the cuff 111 and at the same time facilitates the insertion and removal of the upper arm into the hollow opening 112. Both ends are formed by O-rings, and both the longitudinal direction W and the circumferential direction R are formed. Made of stretch material with slipperiness such as stretchable nylon and spandex.

  The forearm placement unit 130 is rotatably supported (axially supported) on the arm insertion unit 110, and when the electronic sphygmomanometer 100 is not used, a hollow opening (hollow opening) on the distal side in the insertion direction of the arm insertion unit 110 is used. It is comprised so that the hollow opening part (not shown) on the opposite side to the part 112 may be covered. Further, when the electronic sphygmomanometer 100 is used, the electronic sphygmomanometer 100 is configured to rotate to a position substantially parallel to the mounting surface of the electronic sphygmomanometer 100.

2. Detailed configuration of the electronic sphygmomanometer will be described in detail configuration of the electronic blood pressure monitor 100. FIG. 2 is a side view of the electronic blood pressure monitor 100.

  As shown in FIG. 2, the forearm placement unit 130 is supported (axially supported) by the forearm placement unit support unit 212 so as to rotate in the arrow 240 direction. A magnetic member 231 is disposed at the distal end portion of the forearm placement portion 130, and the forearm placement portion 130 covers the hollow opening at the distal end side in the insertion direction of the arm insertion portion 110 when the electronic sphygmomanometer 100 is not used. By rotating in this manner, the magnetic member 211 arranged in the arm insertion portion 110 is coupled.

  For this reason, when the electronic sphygmomanometer 100 is not used, the forearm placement unit 130 is fixed to the arm insertion unit 110. On the other hand, when the electronic sphygmomanometer 100 is used, the forearm placement unit 130 is disengaged from the arm insertion unit 110 by inserting the arm of the subject into the arm insertion unit 110, and the placement surface of the electronic sphygmomanometer 100. And rotate around the forearm placement portion support portion 212 to a substantially parallel position. The rotation of the forearm placement unit 130 is restricted by the forearm placement unit fixing unit 221.

  The forearm placement portion fixing portion 221 is disposed on the main body portion 120 and supports the forearm placement portion 130 so as to be substantially parallel to the placement surface of the electronic sphygmomanometer 100 when the electronic sphygmomanometer 100 is used. To do.

  As described above, when the electronic sphygmomanometer 100 is not used, the arm insertion portion 110 is fixed to the main body portion 120 and the forearm placement portion 130 is fixed to the arm insertion portion 110.

  In use, when the subject inserts his / her arm into the arm insertion portion 110 and the forearm placement portion 130 is pressed, the forearm placement portion 130 is disconnected from the arm insertion portion 110, and the electronic sphygmomanometer 100. It will rotate to a position substantially parallel to the mounting surface. Further, by pulling the main body part 120 toward the front and extending the spine, an upward force is applied to the arm insertion part 110, so that the arm insertion part 110 is disconnected from the main body part 120, and the hollow opening It will rotate until the part 112 becomes an appropriate elevation angle.

  In other words, in the case of the electronic sphygmomanometer 100 according to the present embodiment, one arm (the arm on the blood pressure measurement side) is inserted, the main body 120 of the electronic sphygmomanometer 100 is attracted to the front (left side in the drawing), and the back is stretched. By simply taking the posture, the arm insertion part 110 pivotally supported by the rotation support part 121 can be rotated to an upper angle of 60 degrees and adjusted to an appropriate elevation angle, and the forearm can be adjusted to an appropriate position. The blood pressure (systolic blood pressure, diastolic blood pressure) can be measured with a correct posture without applying abdominal pressure.

  Here, in the electronic sphygmomanometer 100 according to the present embodiment, as shown in FIG. 2, the guide rib 123 is arranged on the lower surface of the main body 120, and the rotation support 121 is positioned at the center of the main body 120 ( A position where the elbow of the subject is placed with the upper arm inserted in the arm insertion portion 110 in the insertion direction distal end (the center position in the arrow 140 direction). The position indicated by 250) is disposed so as to be located on the distal end side with respect to the central position of the main body 120 (the central position in the direction of the arrow 140).

  For this reason, in a state where the upper arm is inserted into the arm insertion portion 110, the elbow of the subject is positioned on the distal end side (dotted arrow 250) from the center position of the main body portion 120, and the main body portion 120 is placed on the elbow. When pulled to the near side, the electronic sphygmomanometer 100 can be easily pulled to the near side (subject side).

  That is, like a conventional electronic sphygmomanometer, it is necessary to perform a high-load work such as pulling the pivotable arm insertion part upward while pulling it upward with the left hand while the upper arm of the right arm is inserted into the arm insertion part. In addition, the electronic sphygmomanometer 100 can be easily pulled to the near side using only the elbow of the inserted arm. As a result, the subject can easily maintain the correct posture during blood pressure measurement.

  In the case of a conventional electronic sphygmomanometer, an arm cannot be inserted immediately, but the main body 120 of the electronic sphygmomanometer 100 is temporarily placed at a position where the correct posture with the back stretched can be taken, the arm insertion unit 110 is released, and the upper arm If the correct posture cannot be achieved, the blood pressure must be measured by adjusting the chair position. On the other hand, in the electronic sphygmomanometer 100 according to the present embodiment, the upper arm is inserted, the main body 120 of the electronic sphygmomanometer 100 is drawn toward the front, and the posture in which the back is extended is troublesome for taking a correct posture. Blood pressure can be measured very easily without any work. Further, unlike the conventional electronic sphygmomanometer, the forearm mounting part does not have a predetermined angle (θ) with respect to the mounting surface of the electronic sphygmomanometer. I don't get to the position. For this reason, the subject can place the forearm at an appropriate position.

3. System configuration of electronic sphygmomanometer Next, the system configuration of the electronic sphygmomanometer will be described with reference to FIG. FIG. 3 is a diagram showing a system configuration of the electronic sphygmomanometer 100 according to the first embodiment of the present invention.

  In FIG. 3, reference numeral 301 denotes a power supply unit that supplies DC power such as AC or a battery. Reference numeral 302 denotes a storage unit such as a nonvolatile memory that stores blood pressure measurement results, measurement time data, and the like for a plurality of times.

  Reference numeral 303 denotes an operation unit for performing various operations including the start switch 114A / stop switch 114B for starting / stopping blood pressure measurement (corresponding to the operation unit 114 in FIG. 1). A display unit 304 displays the blood pressure measurement result and the like, and corresponds to the display unit 113 in FIG. A control unit 305 controls the operation of the entire electronic blood pressure monitor 100.

  The control unit 305 includes a CPU such as a microcomputer, a ROM that stores programs and various data of the entire electronic blood pressure monitor 100 executed by the CPU, a RAM that temporarily stores measurement data and various data as a work area, and a display. A display control unit for controlling the display of the unit 304.

  A pressurized air pump 306 sends pressurized air to the cuff 111. An exhaust valve 307 has both an exhaust valve function for reducing the pressure of the cuff 111 at a constant speed and an exhaust valve function for forcibly exhausting.

  A pressure detection unit 308 detects the pressure of the cuff 111. Reference numeral 311 denotes an A / D converter that performs A / D conversion on the cuff pressure signal detected by the pressure detector 308 and inputs the signal to the controller 305.

  A microphone unit 309 detects a Korotkoff sound signal. Reference numeral 312 denotes a filter / amplifier unit that performs filtering and amplification processing for removing noise components on the Korotkoff sound signal detected by the microphone unit 309. Reference numeral 313 denotes an A / D conversion unit that performs A / D conversion on the detection signal after filtering and inputs the detection signal to the control unit 305.

  Under such a configuration, in the electronic sphygmomanometer 100, after the cuff 111 is pressurized to the maximum blood pressure value or higher, the pressure is reduced to near atmospheric pressure at a constant speed (for example, 2 to 3 mmHg / second). Then, the Korotkoff sound detected by the microphone unit 309 in the depressurization process is acquired, and the cuff pressure value when the amplitude value (pulse wave amplitude value) of the acquired Korotkoff sound component is equal to or greater than the specified value is expressed as the systolic pressure value. Extract as Thereafter, the cuff pressure value when the Korotkoff sound signal becomes equal to or lower than the specified value is extracted as the diastolic blood pressure value.

4). Flow of Blood Pressure Measurement Processing of Electronic Blood Pressure Monitor Next, the flow of blood pressure measurement processing in the electronic blood pressure monitor 100 will be described. Here, the blood pressure measurement process using the Korotkoff sound method using a microphone will be described, but the present invention is not limited to the blood pressure measurement process using the Korotkoff sound method. For example, the blood pressure measurement process using the oscillometric method may be used. Good.

  FIG. 4 is a flowchart showing the flow of blood pressure measurement processing in the electronic sphygmomanometer 100. When the start switch 114A is pressed, the blood pressure measurement process shown in FIG. 4 is started.

  In step S401, initial setting is executed. In step S402, the display unit 304 is inspected (all segments are lit for about 1 second).

  In step S403, it is confirmed that the internal pressure is not applied to the cuff 111, and the pressure value in this state is set to zero.

  In step S404, the exhaust valve 307 is closed and the pressurized air pump 306 is operated to send pressurized air, thereby starting to pressurize the cuff 111 and the pressure detecting unit 308 starts detecting pressure.

  In step S405, it is determined whether or not the internal pressure of the pressurized cuff 111 has reached an appropriate pressure value. If it is determined that the pressure has been increased to an appropriate pressure value, the process proceeds to step S406, where the pressurized air pump 306 is stopped.

  In step S407, the opening of the exhaust valve 307 is controlled to start constant pressure reduction at a pressure reduction speed of 2 to 3 mmHg / sec.

  In step S408, the detection of the microphone sound signal and the cuff pressure signal is repeated until the pressure is reduced to a predetermined pressure. Here, details of the detection processing in step S408 will be described with reference to FIG.

  As shown in FIG. 5, when the detection process is started, the cuff pressure display timer t1 is reset in step S501. In step S502, the microphone sound signal and cuff pressure signal detection timer (signal detection timer) t2 is reset.

  In step S503, it is determined whether or not the signal detection timer t2 has reached 4 mssec. If it is determined in step S503 that the signal detection timer t2 has reached 4 msec, the filter / amplifier unit 312 discriminates and amplifies the Korotkoff sound in step S504. Further, the digital signal is converted by the A / D converter 313.

  In step S505, the cuff pressure signal is detected and amplified by the pressure detector 308, and then converted into a digital signal by the A / D converter 311.

  In step S506, the Korotkoff sound digital signal and the cuff pressure digital signal are stored in the storage unit 302 as a pair. In step S507, it is determined whether the cuff pressure display timer t1 has reached 100 msec.

  If it is determined in step S507 that the cuff pressure display timer t1 has reached 100 msec, the process proceeds to step S508, and the latest cuff pressure value stored in the storage unit 302 is displayed on the display unit 304. In step S509, the cuff pressure display timer t1 is reset.

  On the other hand, if it is determined in step S507 that the cuff pressure display timer t1 has not reached 100 msec, the process proceeds to step S510. In step S510, it is determined whether or not a predetermined cuff pressure value (for example, 30 mmHg) has been reached.

  If it is determined in step S510 that the predetermined cuff pressure value has not been reached, the process returns to step S502. On the other hand, if it is determined in step S510 that the predetermined cuff pressure value has been reached, the detection process is terminated, and the process returns to step S409 in FIG.

  In step S409, the pressure detection operation and the constant speed pressure reduction control are finished, the exhaust valve 307 is fully opened, and the cuff pressure is reduced to atmospheric pressure.

  In step S410, the microphone sound signal stored in the storage unit 302 is observed from old data in time series. Among these, the signal whose amplitude of the waveform observed periodically becomes the specified value or more is recognized as a Korotkoff sound signal, and the cuff pressure signal stored in a pair with the microphone sound signal that recognizes the Korotkoff sound for the first time is used as the systole. Extracted as blood pressure value.

  Further, when it is determined that the Korotkoff sound is not detected for a certain specified time (for example, three times the pulse interval), it is determined that the Korotkoff sound has disappeared. At this time, the cuff pressure signal stored in a pair with the microphone sound signal that recognized the last Korotkoff sound is extracted as a diastolic blood pressure value.

  In step S411, the extracted systolic blood pressure value and diastolic blood pressure value are displayed on the display unit 304, and the blood pressure measurement process ends.
