Description

  The present invention relates to an electronic sphygmomanometer, and in particular, a sphygmomanometer body and an arm band part are formed separately via a tube, the arm band part can be separated from the sphygmomanometer body, and the place where the sphygmomanometer body is installed is measured. The present invention relates to an electronic sphygmomanometer of a type in which measurement can be performed in a state where the back is stretched in a sitting position and no abdominal pressure is applied even if the person is away from the person.

  In recent years, pseudohypertension due to white coat hypertension has been a problem in blood pressure measurement for hypertension treatment performed in medical institutions. As a cause of this pseudohypertension, mental instability such as tension and anxiety in front of a doctor in a hospital is considered. On the other hand, attention has been focused on blood pressure values measured alone in a mentally stable home. For this reason, an electronic sphygmomanometer of the type that is used for home blood pressure measurement and is measured by one person is attracting attention.

  The problem with this type of sphygmomanometer is how to wear the armband on the arm. When the position of the air bag in the armband is not appropriate for the upper arm or when the wrapping strength is not appropriate for the upper arm, the pressure of the air bag in the armband is not correctly applied to the upper arm, and the blood pressure is high. May be. In recent years, to solve this, simply by inserting the arm into the cylindrical armband, the air bag in the armband is automatically placed at the correct position of the arm, and blood pressure is measured with the correct wrapping strength. An electronic sphygmomanometer that integrates a sphygmomanometer body and an arm band that can be used has been developed (see Patent Document 1).

  However, when the user uses a sphygmomanometer of the type in which the sphygmomanometer body and the armband part are integrated, the armband part into which the arm is inserted is integrated with the sphygmomanometer body. When away from the measurer, the measurer is likely to make a measurement in a leaning state. For this reason, the abdomen of the measurer is compressed and the abdominal pressure increases, and as a result, a phenomenon in which the blood pressure increases may be seen. This increase in blood pressure has been pointed out as the occurrence of new pseudohypertension. In addition, an electronic sphygmomanometer of the type that mounts the sphygmomanometer body on the armband part has been developed, but since the drive pump and central control part etc. are also mounted on the armband part, it is heavy and the armband part on the upper arm It is pointed out that it is difficult to measure accurately even if it is worn because of poor balance.

  Therefore, in order to deal with the inconvenience of the occurrence of such pseudo-hypertension, the armband can be separated from the sphygmomanometer body, and even if the place where the sphygmomanometer body is installed is away from the measurer, the measurer is in the sitting position. A type of electronic sphygmomanometer has been developed that can perform measurements without applying abdominal pressure when the back is stretched.

The start / stop button 37 </ b> H, the display unit 31 </ b> H, and the light emitting unit 400 are electrically connected to the sphygmomanometer body 10 side via the wire 3.

First, the structure of the sphygmomanometer body 10 will be described with reference to FIGS.
As shown in FIG. 1, the sphygmomanometer body 10 includes a casing 30 and a display unit 31. The casing 30 is a member having a thin internal space made of plastic, for example, and has an inclined upper surface portion 32, a front end surface portion 33, a rear end surface portion 34, side surface portions 35 and 36, and a bottom surface portion 42. .

  As shown in FIG. 1, an inclined display portion 31 is disposed on the upper surface portion 32 of the casing 30 so that the measurer can easily confirm the display content of the display portion 31. The casing 30 is provided with a start / stop button 37 as an example of a measurement start operation unit, a memory call / time / alarm setting button 38, a mode selection button 39, and a hollow portion 40. This button is used to start or stop the blood pressure measurement operation when the measurer presses the start / stop button 37.

  In FIG. 1, when setting the time, for example, by simultaneously pressing and holding the memory call / time / alarm setting button 38 and the mode selection button 39, the display unit can be operated as an operation / setting / input function. A time setting screen is displayed at 31, and the time displayed on the time setting screen can be set while being selected by the memory call / time / alarm setting button 38.

  In FIG. 1, for example, by pressing the memory call / time / alarm setting button 38, for example, 100 blood pressure measurement records in the past can be displayed on the display unit 31. The maximum blood pressure value, the minimum blood pressure value, the pulse rate, and the date and time displayed on the display unit 31 can be displayed in order each time the memory call / time / alarm setting button 38 is pressed. The mode selection button 39 is a button that is pressed only when the measurer does not store the maximum blood pressure value, the minimum blood pressure value, the pulse value, and the pulse pressure in the memory unit 69, for example.

  As shown in FIG. 3, a recessed portion 40 is formed in the central portion of the upper surface portion 32 of the casing 30 along the Y direction. The recessed portion 40 is formed from the center portion of the casing 30 to the rear end surface portion 34, and the recessed portion 40 has a semicircular portion 40P and a rectangular portion 40R. The recessed portion 40 has a semicircular portion 40P. A circular start / stop button 37 is arranged at the center. A groove portion 41 is formed in the rectangular portion 40 </ b> R of the recessed portion 40.

As shown in FIG. 3, a magnet 40 </ b> M is disposed in the casing 30 in the vicinity of the start / stop button 37 and the groove portion 41 of the recessed portion 40. The magnet 40M is, for example, a rectangular plate-shaped permanent magnet, but is not particularly limited to a shape, and may be a circular shape or an elliptical shape. Further, the magnet 40M may be exposed to the outside of the casing 30.
The display unit 31 is disposed along the X direction between the recessed portion 40 and the front end surface portion 33 in FIG. For example, a liquid crystal display device can be used as the display unit 31. As shown in FIG. 1, for example, the display unit 31 includes a maximum blood pressure value, a minimum blood pressure value, a pulse rate, a pulse pressure, and a display mark during measurement operation. Various measurement values such as battery replacement display marks can be displayed.

  As shown in FIGS. 1 and 2, the side portions 35 and 36 are formed in a curved surface so that the measurer can easily hold the blood pressure monitor main body 10. The memory call / time / alarm setting button 38, the mode selection button 39, the volume button 39V, and the guidance repeat button 39S are arranged in the vicinity of the display unit 31 on the upper surface 32. As shown in FIG. 1, a speaker 43, two pumps 44 and 45, an exhaust valve 46, a control valve 47, a circuit board 48 including a control system, and a memory unit 69 are arranged inside the casing 30. Has been. The speaker 43 is provided to output a voice guide or a music guide.

  Next, the structure of the armband portion 2 will be described with reference to FIGS. 1 to 3 and FIGS. 4 and 5.

  FIG. 4 is a perspective view showing a structural example of the armband portion 2. FIG. 5 is a cross-sectional view showing an example of the internal structure of the armband portion 2.

  As shown in FIG. 3B, the armband portion 2 can be inserted into the upper arm T as shown in FIGS. 1 and 2 in order to insert and compress the upper arm T of the measurer during blood pressure measurement. It has a substantially cylindrical structure (tubular body) with both ends cut off. Thus, unlike the normal armband portion, the armband portion 2 does not need to be wound around the upper arm T of the measurer and can be inserted into either the left or right upper arm T, and the measurer can easily measure blood pressure. Can do.

  As shown in FIGS. 4 and 5, the armband portion 2 includes a hard main body case 11, an air bag (also referred to as a cuff) 14, an outer cloth 16, and an inner cloth cover 17 </ b> C. The total weight of the armband portion 2 is preferably 330 g to 410 g, and the weight is reduced so that an elderly person can easily operate with one hand.

  The body case 11 shown in FIGS. 4 and 5 is formed of, for example, plastic and has a substantially cylindrical structure, and has an opening 11P and an opening 11R. As shown in FIG. 1, the main body case 11 is formed so as to taper in the direction D1, and the diameter L1 of the opening 11P is larger than the diameter L2 of the opening 11R. For example, L1 is preferably 138 to 142 mm, L2 is preferably 126 to 130 mm, and the thickness of the main body case 11 is preferably 2 to 3 mm. This dimension is a dimension suitable for inserting the upper arm of the measurer, and the main body case 11 has a shape suitable for blood pressure measurement of a general measurer of approximately 90% or more. The main body case 11 has, for example, a substantially fan-shaped gripping portion 11H on the opening 11R side.

  For example, the operation of inserting the upper arm T of the left arm shown in FIG. 5 into the insertion hole 77 in the D1 direction or removing the upper arm T in the opposite direction can be performed with the gripping part 11H with the right hand. Further, the operation of inserting the upper arm T of the right arm into the insertion hole 77 in the direction D1 or removing the upper arm T in the opposite direction can be performed by holding the holding portion 11H with the left hand. Thereby, the measurer can easily perform the attaching operation or the detaching operation of the armband portion 2 with respect to either the left or right upper arm T.

As shown in FIGS. 1 and 2, the above-described start / stop button 37H is provided on the upper portion of the cylindrical main body case 11, and a display portion 31H is provided in the vicinity thereof. The position of the start / stop button 37H is opposite to the position of the plate member 210 described later.
In addition, the start / stop button 37H is arranged such that when the grip portion 11H is gripped, the thumb is placed on the start / stop button 37H, and the grip portion 11H is located closer to the opening portion 11R. The arrangement of the start / stop button 37H is not limited to this embodiment. For example, the main body case 11 is gripped with the right hand using the upper arm of the left arm as a measurement site (at this time, the main body case 11 also serves as a gripping portion). ) When the armband part 2 is inserted into the arm, it is arranged at a position where the index finger or the thumb can be applied. May be. Thereby, when the upper arm T is inserted into the armband part 2, the start / stop button 37H starts the measurement after the action (operation) to be inserted into the arm is completed because the armband part 2 has a measurement start switch. The switch can be pushed and measurement can be started easily. For example, even if a person who needs measurement immediately after getting up wants to perform measurement while lying down, only one action to be inserted into his / her arm is sufficient, so that measurement can be performed without getting up.

  At the time of blood pressure measurement, measurement information such as the highest blood pressure value and the lowest blood pressure value can be reliably recognized at a position closer to the measurer from the display unit 31H arranged in the armband portion 2. The display unit 31H is not limited to the present embodiment. For example, a plurality of display units 31H may be provided so that the display unit 31H can be confirmed regardless of whether the left or right upper arm is inserted into the armband unit 2. Further, similarly to the display unit 31 of the sphygmomanometer main body 10, a memory call / time / alarm setting button, a mode selection button, a volume button, and a guidance repeat button may be arranged near the display unit 31H. Thereby, when the blood pressure is measured, the measurer does not need to check the display unit 31 of the sphygmomanometer body 10 located at a distant place, but from the display unit 31H arranged in the armband unit 2, Measurement information such as minimum blood pressure and pulse rate can be obtained. Furthermore, since the various buttons described above including the start / stop button 37H are arranged in the vicinity, blood pressure measurement can be easily performed without reaching the sphygmomanometer body 10.

  As shown in FIGS. 1 and 2, the light emitting means 400 is located on the upper portion of the main body case 11 and near the opening 11 </ b> P. The light emitting means 400 is an LED lamp, and emits light when blood pressure measurement is completed, thereby visually informing the measurer. Thereby, not only the notification of the measurement completion from the speaker 43 or the notification of displaying the measurement completion on the display unit 31 but also the notification of the light emitting means 400 located closer to the measurer is surely notified to the measurer. Can do. The notification color of the light emitting means 400 may vary depending on various colors. For example, it may mean a measurement error in the case of red, a measurable state in the case of blue, a measurement completion in the case of green, etc. good. In addition, in the case of blinking or lighting, for example, in the case of blinking blue, the content of notification may be classified as being during blood pressure measurement or the like.

  In addition, the light emitting means 400 has an effect of not only informing the measurement status and the like, but also making it possible to know the position of the armband portion even in measurement at night or early morning darkness. In this case, as described above, since the light emitting unit 400 is electrically connected to the blood pressure monitor main body 10 side via the wire 3, a motion sensor (not shown) such as a tilt sensor, an acceleration sensor, or a gyroscope is electronically connected. By providing the sphygmomanometer 1 at an appropriate place, for example, the armband part 2, the shock or vibration that has moved by touching the armband part 2 can be detected, and the position of the armband part 2 can be confirmed for a predetermined time, for example. The light may be emitted from 30 seconds to 30 seconds for checking the measured value after the measurement is completed after confirming the position of the armband portion 2. At this time, the light emission time may be adjusted according to the preference of the measurer. Since the above-described motion sensor is electrically connected, the blood pressure monitor main body 10 may be provided to detect an impact or vibration that has moved by touching the blood pressure monitor main body 10. Furthermore, the light emitting means 400 has been described as an electrically connected LED lamp as the present embodiment, but as the light emitting means 400 that makes it possible to know the position of the armband portion even in measurement in the dark at night or early morning. Alternatively, light may be emitted without driving the power supply battery by using a hemispherical raised portion using a phosphorescent material such as zinc sulfide or strontium aluminate, or by applying a phosphorescent paint to the grip portion 11H. This makes it difficult to visually confirm the position of the electronic sphygmomanometer 1 even in the dark at night or in the early morning, and the light emitting means 400 emits light without having to find the start / stop button 37H of the armband 2 by groping. Blood pressure measurement can be easily performed.

  As shown in FIGS. 1 and 3, a magnetic adsorption plate member 210 as an example of a magnetic adsorption member is provided on the lower portion of the main body case 11. The plate member 210 is, for example, a metal plate, is formed so as to be long along the axial direction of the main body case 11, and is magnetically attracted by the magnet 40 </ b> M of the sphygmomanometer main body 10. The plate member 210 and the magnet 40M constitute a fixing means 250 for fixing (or coupling) the armband portion 2 to the blood pressure monitor main body 10.

The fixing means 250 has such a force that the binding force between the sphygmomanometer body 10 and the armband part 2 is released when the armband part 2 is lifted from the sphygmomanometer body 10. Thereby, when the measurer does not measure blood pressure, the armband portion 2 does not easily roll off the blood pressure monitor main body 10, and when the measurer wants to measure blood pressure, the armband portion 2 is difficult to remove from the sphygmomanometer body 10. Thereby, even if the armband part 2 is a separate body from the sphygmomanometer main body 10, it is easy to use.

  More preferably, the force with which the magnet 40M magnetically attracts the plate member 210 can be set so as to exceed the weight of the sphygmomanometer body 10, for example. Thereby, when the measurer carries the electronic sphygmomanometer 1, when the measurer lifts only the armband part 2 without holding the sphygmomanometer body 10, only the sphygmomanometer body 10 from the armband part 2. Inadvertent falling can be prevented.

  Further, as already described, since the plate member 210 is formed to be elongated along the axial direction of the main body case 11, the armband portion 2 is magnetically attracting the blood pressure monitor main body 10. The sphygmomanometer body 11 can be moved in the Y direction along the recessed portion 40 of the sphygmomanometer body 11. As a result, the measurer can move the armband portion 2 with respect to the sphygmomanometer body 10 in the Y direction while maintaining the magnetic attraction force. 2 is retracted, and the inconvenience that the display unit 31 becomes invisible by the armband unit 2 can be solved. For this reason, the measurer can easily confirm the display content of the display unit 31 and the usability is improved.

  Furthermore, as shown in FIG. 1, the start / stop button 37 is located at the lower part of the armband portion 2 when the armband portion 2 is disposed in the recessed portion 40 of the sphygmomanometer body 10. In other words, the measurer cannot press the start / stop button 37 when the armband portion 2 is fixed. When the measurer removes the armband portion 2 from the depression 40 of the sphygmomanometer body 10 against the magnetic attractive force, the start / stop button 37 is exposed, and the measurer presses the start / stop button 37. Can be pressed.

  The air bag 14 shown in FIGS. 4 and 5 is formed of a stretchable material such as vinyl chloride, urethane, synthetic rubber, or natural rubber. The upper arm T is compressed into the air bag 14 by being inflated by being supplied with air through the tube 4 by the operation of the pumps 44 and 45 indicated by broken lines in the blood pressure monitor main body 10 shown in FIG. Since the internal pressure of the air bag 14 is reduced at a constant speed, the air can be gradually exhausted from the air bag 14 by the control valve 47, and when the measurement is completed, the air is removed from the air bag 14 by the exhaust valve 46. Can be exhausted quickly. The detailed structure of the air bag 14 will be described later.

  The outer cloth 16 shown in FIGS. 4 and 5 is disposed between the outer side of the air bag 14 and the inner side of the main body case 11 and corresponds to an outer member that is a deformable and non-stretchable cloth member. The inner cloth cover 17C shown in FIGS. 4 and 5 is also referred to as cuffing and can cover the inside of the air bag 14. By arranging the inner cloth cover 17C, the measurer can smoothly insert and remove the upper arm. You can. The inner cloth cover 17C can be detachably disposed inside the air bag 14 described above, and includes a stretchable cloth portion 17D and two O-ring-shaped ring members 17F and 17G. The cloth portion 17D is formed of a slip stretch material such as nylon or spandex that can expand and contract in both the length direction and the circumferential direction.

  6A is a perspective view showing the unit UT of the outer cloth 16 and the air bag 14, and FIG. 6B is a perspective view of the unit UT seen from another direction. ) Is a perspective view showing a state in which the unit UT is folded.

  As shown in FIGS. 6A and 6B, the unit UT can be bent into four to form an opening G having a substantially square cross section. Since the unit UT has the four bent portions 200, the unit UT can be easily folded as shown in FIG.

  7A is a perspective view showing the air bag 14 and the microphone M, and FIG. 7B is a view showing the air bag 14, the outer cloth 16, the inner cloth cover 17C, and the microphone M. As shown in FIG. 7, two microphones M are attached to the air bag 14, and the two microphones M face each other.

  Here, a structural example of the air bag 14 will be described.

  FIG. 8 shows an example of a sheet for forming the air bag 14.

  The sheet SW shown in FIG. 8 is, for example, a transparent plastic sheet having a substantially rectangular shape, and is formed of, for example, a substantially rectangular plastic sheet having no stretchability, for example, a polyurethane sheet. The sheet SW includes a connecting pipe with filter 220, a cord hook 221, four broken line portions 222, joint portions 223 and 224, and two microphone holding portions 225.

  The connection pipe 220 connects the ends of the tube 4 shown in FIG. The cord hook 221 hangs the wire 3 and the tube 4 shown in FIG. The joining portions 223 and 224 form the air bag 14 by thermocompression bonding. Each of the microphone holding units 225 can hold the microphone M. The sheet SW can be bent at the four broken line portions 222 to form the air bag 14 having the shape shown in FIG.

  FIG. 9 shows an example of a process for forming the air bag 14. FIG. 10 is a diagram illustrating a state in which the inner surface of the air bag 14 is in contact with the measurement target surface HM of the measurer.

  Next, an example of performing blood pressure measurement according to the procedure of the blood pressure measurement program using the electronic blood pressure monitor 1 described above will be described.

The blood pressure measurement program has, for example, a normal mode M1, a systolic blood pressure mode M2, and a diastolic blood pressure mode M3. Below, these modes are demonstrated in order.

(Normal mode M1)
The plate member 210 of the main body case 11 of the armband portion 2 shown in FIG. 1 is formed so as to be elongated along the axial direction of the main body case 11 as already described, and the armband portion 2 is formed of this plate member. 210, the magnet 40M of the sphygmomanometer main body 10 is magnetically attracted and coupled to the recessed portion 40 of the sphygmomanometer main body 10. As shown in FIG. 3, the measurer lifts the armband portion 2 from the hollow portion 40 of the sphygmomanometer body 10 against the magnetic attractive force of the magnet 40 </ b> M, thereby lifting the armband portion 2 to the sphygmomanometer body. It can be easily removed from the ten recessed portions 40. Thus, when the measurer measures the blood pressure, the armband portion 2 can be easily detached from the blood pressure monitor main body 10. Thereby, even if the place where the sphygmomanometer main body 10 is installed is away from the measurer, the measurer can easily measure blood pressure in a state where his / her back is stretched and no abdominal pressure is applied.

Preferably, the force with which the magnet 40M magnetically attracts the plate member 210 can be set so as to exceed the weight of the sphygmomanometer body 10, for example. Thereby, when the measurer carries the electronic sphygmomanometer 1 and only the arm band part 2 is lifted without holding the sphygmomanometer body 10, only the sphygmomanometer body 10 falls carelessly from the arm band part 2. Can be prevented.

  As shown in FIG. 1, when the armband portion 2 is placed in the recessed portion 40 of the sphygmomanometer main body 10, the start / stop button 37 is positioned below the armband portion 2, The start / stop button 37 is not exposed to the outside unless the armband portion 2 is lifted and removed from the recessed portion 40 of the sphygmomanometer body 10. As a result, the measurer can press the start / stop button 37 after the armband portion 2 is lifted and is ready to measure through the upper arm T, so the start / stop button 37 is inadvertently not measured. There is no such thing as pushing.

  The start / stop button 37H is electrically connected to the sphygmomanometer main body 10 side via the wired 3 as described above, but the middle of the wired 3 connecting the start / stop button 37H and the sphygmomanometer main body 10. 11, the reed switch 410 shown in FIG. 11 is provided on the armband portion 2 side so as to be positioned above the magnet 40M when the armband portion and the sphygmomanometer body are fixed. When the armband 2 and the sphygmomanometer body 10 are fixed, the reed switch 410 is turned off because a magnetic field is applied from the outside by the magnet 40M, and measurement is performed even if the start / stop button 37H is pressed. It has a structure that does not start. That is, when the armband portion 2 and the sphygmomanometer body 10 are fixed, the start / stop button 37H is inactive. When the armband 2 and the sphygmomanometer main body 10 are separated from each other, that is, when not affected by the magnet 40M, the reed switch 410 is ON, and measurement is performed by pressing the start / stop button 37H. Start. Accordingly, it is possible to prevent the measurer from erroneously inserting and measuring the arm while the armband portion 2 and the sphygmomanometer body 10 are fixed (mounted state).

Next, the measurer inserts, for example, the right upper arm from the opening 11P to the opening 11R while holding the holding part 11H.

  When the measurer presses the mode selection button 39 shown in FIG. 1 to select the normal mode M1, the speaker 43 notifies the measurer by sound that the selected mode is the normal mode M1. The measurer presses the start / stop button 37 or 37H in FIG. 1 to start blood pressure measurement. The pumps 44 and 45 in FIG. 1 pressurize the air bag 14 at full speed, and the two microphones M detect the blood flow sound (blood vessel information) of the measurer and the arm band part 2 is at full speed until the pulse disappears. The air bag 14 is pressurized. When the control system 56 determines the disappearance of the pulse, the pressure increase in the armband 2 is stopped.

  Then, the inside of the armband 2 is gradually reduced in pressure (for example, 2 to 5 mmHg / second), and the maximum blood pressure value and the minimum blood pressure value are detected. The maximum blood pressure value, the minimum blood pressure value, the pulse rate, and the like are displayed on the display unit 31 in FIG. 1, and the pumps 44 and 45 and the exhaust valve 46 are operated to rapidly exhaust the air bag 14 in the armband 2. Thus, when the maximum blood pressure value and the minimum blood pressure value can be displayed on the display unit 31, the pressure on the upper arm of the measurer can be immediately eliminated by quickly exhausting the air bag 14 in the armband portion 2. , The burden on the measurer can be reduced. Further, the maximum blood pressure value, the minimum blood pressure value, the pulse rate and the like are displayed on the display unit 31 and the display unit 31H of FIG. 1, and the maximum blood pressure value, the minimum blood pressure value, and the pulse rate by voice from the speaker 43 of the sphygmomanometer body 10 are displayed. Measurement information such as voice announcements and audio guidance announcements can be generated. Accordingly, measurement information such as the maximum blood pressure value and the minimum blood pressure value, other guidance information, and the like can be recognized by the measurer by voice or screen display from the speaker 43 disposed in the blood pressure monitor main body 10.

(High blood pressure mode M2)
Further, the measurer inserts the right upper arm, for example, from the opening 11P to the opening 11R while holding the holding part 11H. When the measurer presses the mode selection button 39 shown in FIG. 1 and selects the systolic blood pressure mode M2, the speaker 43 notifies the measurer by sound that the selected mode is the systolic blood pressure mode M2. The measurer presses the start / stop button 37 or 37H in FIG. 1 to start blood pressure measurement. The pumps 44 and 45 of FIG. 1 pressurize the air bag 14 at full speed, and the two microphones M detect the blood flow sound of the measurer and the air bag 14 in the armband portion 2 at full speed until the pulse disappears. Boost. When the control system 56 determines the disappearance of the pulse, the pressurization of the air bag 14 in the armband 2 is stopped.

Then, the pressure is gradually reduced (for example, 2 to 5 mmHg / second), and the speaker 43 in FIG. 1 audibly changes the pressure value of the air bag 14 in the armband portion 2 for each cuff value at the time of pressure reduction, for example, every 10 mmHg. Announce and detect only systolic blood pressure. Thereafter, the loudspeaker 43 in FIG. 1 announces the maximum blood pressure value and the pulse rate with a voice guide, and operates the pumps 44 and 45 and the exhaust valve 46 to rapidly exhaust the air bag 14 in the armband portion 2. As a result, the pressure on the upper arm of the measurer can be immediately eliminated by quickly exhausting the inside of the armband part 2 while announcing the maximum blood pressure value and the pulse rate with a voice guide, thereby reducing the burden on the measurer. .
Further, the maximum blood pressure value and the pulse rate are displayed on the display unit 31 and the display unit 31H of FIG. 1, and the measurement information such as the maximum blood pressure value and the pulse rate by voice from the speaker 43 of the sphygmomanometer main body 10, and the voice. Operation guide announcements and music guide announcements can be generated.
As a result, when measuring blood pressure, the measurer can reliably recognize measurement information such as the maximum blood pressure value and pulse rate, and other guidance information such as voice guidance data or music data by voice or screen display. .

(Minimum blood pressure mode M3)
Further, the measurer inserts the right upper arm, for example, from the opening 11P to the opening 11R while holding the holding part 11H. Thereafter, when the measurer presses the mode selection button 39 shown in FIG. 1 and selects the diastolic blood pressure mode M3, the speaker 43 notifies the measurer by sound that the selected mode is the diastolic blood pressure mode M3. . The measurer presses the start / stop button 37 or 37H in FIG. 1 to start blood pressure measurement. The pressure is gradually increased (for example, 2 to 5 mmHg / second), and the speaker 43 in FIG. 1 announces the pressure value of the air bag 14 in the armband portion 2 for each cuff value at the time of pressure increase, for example, every 10 mmHg, Detect minimum blood pressure. Thereafter, when the pulse disappears, the pressurization is stopped, and the speaker 43 in FIG. 3 announces the minimum blood pressure value by voice guide, and the pumps 44 and 45 and the exhaust valve 46 are operated to air in the armband 2. The bag 14 is quickly exhausted.

Further, the minimum blood pressure value and the pulse rate are displayed on the display unit 31 and the display unit 31H of FIG. Operation guide announcements and music guide announcements can be generated.
Accordingly, measurement information such as the maximum blood pressure value and the minimum blood pressure value, other guidance information, and the like can be recognized by the measurer from the speaker 43 disposed in the sphygmomanometer body 10 by voice or screen display.

  In any mode, the volume of the speaker 43 can be adjusted by operating the volume button 39V shown in FIG. If the guidance repeat button 39S is pressed, the voice guidance of the operation guide can be repeatedly notified.
