Description

  The present invention relates to a sphygmomanometer having a function that allows a person to be measured (user) to listen to music before blood pressure measurement so that the person to be measured can perform blood pressure measurement in a relaxed state.

  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 is focused on blood pressure values measured at home where the measurement subject is mentally stable. For this reason, an electronic sphygmomanometer used for blood pressure measurement at home is drawing 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 upper arm is not correctly compressed by the air bag in the armband, and the blood pressure is high. May be. In recent years, in order to solve this, simply by inserting the arm into the cylindrical armband, the air bag for ischemia of the armband is automatically placed at the correct position of the arm, with the correct winding strength. An electronic sphygmomanometer has been developed that integrates a sphygmomanometer body and an armband that can measure blood pressure (see Patent Document 1).

  However, when the person to be measured uses the above sphygmomanometer, the armband part into which the arm is inserted is integrated with the sphygmomanometer body, so that the position of the sphygmomanometer body is separated from the front of the person to be measured The person being measured is likely to perform measurement in a leaning state. For this reason, the abdomen of the person to be measured 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 is pointed out as the occurrence of new pseudohypertension.

  Therefore, it has been proposed that the armband portion is formed separately from the main body of the sphygmomanometer, and the armband portion has a rigid case, and an air bag for ischemia is disposed in this case. ing. This allows the armband part to be separated from the sphygmomanometer main body when the person to be measured measures blood pressure in the sitting position, so that the blood pressure meter does not lose the convenience of being able to measure by simply inserting the upper arm into the armband part. Even if the installation location of the main body is far away from the person to be measured, the blood pressure can be measured in a state where the measurer is correct and the abdominal pressure is not applied when the back is stretched.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.
The embodiments described below are preferred specific examples of the present invention, and thus various technically preferable limitations are given. However, the scope of the present invention is particularly limited in the following description. Unless otherwise stated, the present invention is not limited to these embodiments.
FIG. 1 is a perspective view showing the entire embodiment of the blood pressure monitor of the present invention. FIG. 2A is a perspective view of the sphygmomanometer body of the sphygmomanometer shown in FIG. 1 as viewed from the left rear side. FIG. 2B is a perspective view of the sphygmomanometer body of the sphygmomanometer shown in FIG. 1 as viewed from the right rear side.

  The sphygmomanometer 1 shown in FIGS. 1 and 2 shows a preferred example of a sphygmomanometer and is also called an electronic sphygmomanometer. In this sphygmomanometer 1, the armband part 2 and the sphygmomanometer body 10 are separate, and the armband part 2 shown in FIG. 1 is used separately from the sphygmomanometer body 10 shown in FIGS. 1 and 2. Thus, the blood pressure monitor 1 is different from the integrated blood pressure monitor in which the armband portion and the main body are integrated, and the place where the blood pressure monitor main body 10 is installed from the measured person when the measured person measures in the sitting position. Even if it is away from the front, blood pressure can be measured in a state where the back is stretched and abdominal pressure is not applied by attaching the armband portion 2 to the upper arm T.

The armband part 2 shown in FIG. 1 is also called a cuff, and the armband part 2 has a constant (predetermined) outer peripheral length, and is a soft cylinder body that is made of a foldable and soft material. Yes, it has two openings 11P and 11R.
As shown in FIG. 1, when the armband 2 is attached to the upper arm T of the measurement subject, the opening 11P is positioned on the finger side, and the opening 11R on the opposite side is positioned on the shoulder side. The inner diameter of the opening 11R is larger than the inner diameter of the opening 11P. As a result, the finger of the person to be measured can be easily inserted from the opening 11R side to the opening 11P, and the armband 2 is held on the upper arm T above the elbow of the person to be measured and blood pressure is maintained. It comes to measure.

As shown in FIG. 1, the armband portion 2 includes a hemostasis air bag 14 for isolating the upper arm T, two K sound detection air bags 50 for detecting a K sound (Korotkoff sound) signal, An arm detection sensor 800 as one arm insertion notification unit is incorporated.
This air bag 14 for ischemia pressurizes the artery of the upper arm T by supplying air from the sphygmomanometer main body 10 side to block blood. The air capacity of the air bag 14 for ischemia is larger than the air capacity of the air bag 50 for detecting K sound. As shown in FIG. 1, the two K-sound detection air bags 50 are arranged so as to face each other with the upper arm T sandwiched between them when the armband portion 2 is attached to the upper arm T. These K sound detection air bags 50 are air bags for detecting K sound. The K sound raises the internal pressure of the air bag 14 of the armband portion 2 to the maximum blood pressure or higher to temporarily close the blood vessel. After that, the sound pressure signal is a sound signal that can be detected until the internal pressure falls below the maximum blood pressure, the internal pressure drops below the minimum blood pressure, and the vessel occlusion disappears. The arm detection sensor 800 is disposed, for example, on the inner side of the armband portion 2, for example, on the opening 11R side.

  As shown in FIG. 1, the armband 2 and the sphygmomanometer body 10 are connected via air tubes 4 and 5 and an air plug 6. The air tubes 4 and 5 are preferably flexible elastomer tubes that constitute a multiple cylinder tube (also referred to as a multiple conduit). The air tubes 4 and 5 are integrally formed over the entire length (or substantially over the entire length). The air tube 4 as the first air tube is used for supplying and exhausting air to and from the air bag 14 for the ischemia of the armband portion 2, and the air tube 5 as the second air tube is a two air tube that detects a K sound signal. It is used to supply and exhaust air to / from the K sound detection air bag 50. The air tube 4 is a thicker tube than the air tube 5, and the inner diameter and outer diameter of the air tube 4 are set larger than the inner diameter and outer diameter of the air tube 5. As a result, the air tube 4 can quickly supply and exhaust air to and from the air bag 14 having a large air capacity.

With reference to FIG. 1 and FIG. 3, the structural example of the armband part 2 is demonstrated.
3A is a cross-sectional view showing an example of the internal structure of the armband portion 2, FIG. 3B is a front view showing a state in which the armband portion 2 is folded, and FIG. It is a perspective view which shows the state which folded the armband part 2. FIG.
As shown in FIGS. 1 and 3, the armband portion 2 is a cylindrical member that is not cut along the outer circumferential direction, and has an outer periphery of a predetermined (constant) length. The upper arm T of the person to be measured can be passed through the part 2. As shown in FIG. 3 (B) and FIG. 3 (C), the armband portion 2 has the flexibility that the person to be measured can easily fold, and as shown in FIG. 1 and FIG. 3 (A), For example, an outer cloth 16, an inner cloth 17, a hemostasis air bladder 14 for isolating the upper arm T, two K sound detection air bladders 50 for detecting a K sound signal, and an arm detection sensor 800 are provided. Yes.

  As shown in FIG. 3 (A), the inner surface of the outer cloth 16 and the outer surface of the inner cloth 17 enclose the air bag 14 for ischemia and two air bags 50 for detecting K sound. In order to create a doughnut-shaped space in which the cloth 17 can store the air bag 14 for ischemia and the two air bags 50 for detecting K sound, both ends of the outer cloth 16 and both ends of the inner cloth 17 are, for example, Joined by sewing. As illustrated in FIG. 3A, the two K sound detection air bags 50 are preferably positioned closer to the opening 11P side than the intermediate position in the longitudinal direction (axial direction) of the armband portion 2 (see FIG. 3A). It is better to place it at a position closer to the finger than the shoulder side. In this way, one of the two K-sound detection air bags 50 can be applied to a portion corresponding to the artery of the upper arm T. Thereby, although it is a simple structure, the upper arm T can be reliably pressurized to block the artery, and the K sound can be detected by the K sound detecting air bag 50.

  The outer cloth 16 shown in FIG. 3 (A) is a cylindrical body that covers the outer surface of the air bag 14 for ischemia, and is formed of a non-stretchable material in the circumferential direction and the longitudinal direction. It is a fabric member that has very low or no properties. Thus, when the outer fabric 16 supplies air into the ischemic air bag 14 and the two K sound detecting air bags 50, the ischemic air bag 14 and the two K sound detecting air bags 50 are connected to the armband. It is possible to prevent the air bladder 14 and the two K sound detecting air bags 50 from expanding toward the upper arm T side, which is the inner side in the radial direction. For this reason, the pressure of the air bag 14 for ischemia and the two air bags 50 for detecting K sound can be applied to the upper arm without escaping to the outside of the armband portion 2, and accurate blood pressure measurement can be performed. .

  The outer fabric 16 shown in FIG. 3 (A) can employ, for example, a fabric (201BE) that is difficult to stretch, and the tensile strength is a value measured by the JIS L1096-A method, with a warp of 1430 N / in to 1460 N / in, Is 810 N / in to 850 N / in. Furthermore, it is preferable that the length is 1430 N / in to 1460 N / in and the width is 810 N / in to 850 N / in. If both the length and the width are smaller than this numerical range, the suppression of the outward expansion of the air bag 14 is weakened, and if it is larger than this numerical range, the insertion of the upper arm T may be affected. As the outer cloth 16, for example, when a 100% polyester fabric is used, the length is 1445 N / in and the width is 827 N / in.

  On the other hand, the inner cloth 17 shown in FIG. 3 (A) is a cylindrical body that covers the inner surfaces of the ischemic air bladder 14 and the two K sound detecting air bladders 50, is deformable and has elasticity, and This is a contact cloth portion that contacts the surface to be measured. The inner cloth 17 may be a stretchable cloth member that is elastic and has elasticity, for example, and the tensile strength is 94.9 N / in in length as measured by the JIS L1096-A method. The width is 150.7 N / in. Tensile elongation is 517% in length and 400% in width as measured by JIS L1096-A method. The inner fabric is, for example, a fabric made of 80% nylon and 20% polyurethane. The inner cloth 17 is made of a material that is stretchable so that the ischemic air bladder 14 and the two K sound detecting air bladders 50 can be expanded toward the surface to be measured of the upper arm T, and the armband portion 2. Is inserted from the hand of the person to be measured and is slid to the upper arm T of the upper part of the elbow, so that a smooth material such as a jersey material is used.

  As shown in FIGS. 1 and 3A to 3C, the opening closing member 30 is on the opening 11P side inside the armband portion 2, and the air tube 4 and the air tube 5 are led out. It is provided on the (connected) side. The opening closing member 30 can use, for example, a removable surface fastener, and has a male member 31 and a female member 32 of the surface fastener. The male member 31 and the female member 32 are fixed at positions facing each other inside the armband portion 2, and the male member 31 and the female member 32 are attached and detached as shown in FIGS. 3 (B) and 3 (C). By connecting in a possible manner, only the opening 11P side of the armband portion 2 can be closed, and the opening 11R can be kept open.

  Thereby, by providing the opening closing member 30 for the armband part 2, when the person to be measured tries to measure blood pressure through the hand with respect to the armband part 2, from the closed opening part 11P side. Without passing the hand, it is possible to pass the hand without getting lost from the open opening 11R side. For this reason, it can prevent that a to-be-measured person inserts a hand back into the armband part 2 accidentally from the opening part 11P side. If the person to be measured is reversely inserted into the armband portion 2 from the opening 11P side, the K sound detection air bag 50 does not properly hit the artery of the upper arm T, and blood pressure cannot be measured accurately. . Further, by providing the opening closing member 30 with respect to the armband portion 2, it can be easily folded when the armband portion 2 is not used.

  As shown in FIGS. 1 and 3, the armband portion 2 has a tag 33 that is preferably a direction visual recognition member. The tag 33 is on the opening 11R side, and is fixed to the outer fabric 16 by using, for example, an adhesive or by sewing. The tag 33 is provided so as to protrude along the V direction from the end of the armband portion 2 on the opening 11R side, and can be made of, for example, a cloth member or a plastic member. As shown in FIG. 3A, when the person to be measured inserts his left arm into the armband portion 2 and measures blood pressure, for example, the user grasps the tag 33 with the finger F of the right arm and holds the armband portion 2 in the V direction. Can be moved to. The tag 33 can preferably be labeled with a “shoulder side” display 33S.

  As a result, the measurement subject can easily attach the armband portion 2 to the upper arm T simply by grasping the tag 33 and moving in the V direction, and the attachment direction of the armband portion 2 is clear. Therefore, it is possible to pass the hand without hesitation from the opening 11R side. For this reason, it can prevent that a to-be-measured person inserts a hand back into the armband part 2 accidentally from the opening part 11P side. That is, since only the opening 11P on the side of the air tubes 4 and 5 can be closed, it is possible to easily prevent the person to be measured from wearing in the reverse direction with respect to the upper arm, and the person to be measured is against the upper arm T. Can be installed in the correct direction.

Next, a structural example of the sphygmomanometer body 10 will be described with reference to FIGS. 1 and 2.
As shown in FIGS. 1 and 2, the sphygmomanometer body 10 includes a housing part 60, a display surface part 61, and a holding part 62 for the armband part 2. The housing part 60, the display surface part 61, and the holding part 62 are made of an electrically insulating material such as plastic. The display surface portion 61 is provided on the front surface side of the housing portion 60 and is inclined so that the measurement subject can easily see the display content displayed on the display portion 63. The inclination angle θ of the display surface portion 61 is, for example, 60 degrees. Is set to about.

As shown in FIGS. 2A and 2B, the housing 60 includes side surfaces 68 and 69, a back surface 66, a rectangular front opening 70 indicated by a broken line, and a housing 60. It has an upper surface portion 71 projecting from the bottom portion 72 and a bottom portion 72.
As shown in FIG. 1, the display surface unit 61 includes a display unit 63, a transparent protective plate 64 such as an acrylic plate, and a frame-shaped holding member 65. The display unit 63 is held by a holding member 65, and the protective plate 64 is fixed to the holding member 65 to protect the surface of the display unit 63. The holding member 65 is detachably attached to the front surface side opening 70 indicated by a broken line of the housing portion 60. By removing the holding member 65 from the housing unit 60, the inside of the housing unit 60 can be exposed through the front side opening 70 indicated by a broken line of the housing unit 60. Thereby, repair and replacement | exchange of the circuit board etc. which are arrange | positioned in the housing | casing part 60 can be performed easily.

As shown in FIG. 2, the arm belt holding portion 62 is detachably attached to the back side of the housing portion 60. Thereby, when the holding | maintenance part 62 is unnecessary, it can remove from the housing | casing part 60. FIG. FIG. 4 shows a state where the folded armband portion 2 is detachably housed on the back surface 66 side of the housing portion 60 using the holding portion 62.
As shown in FIG. 2, the holding part 62 of the armband part has a holding surface 62A and a leg part 62B. An insertion port 67 is formed on the lower side of the housing unit 60. The distal end portion 62C of the leg portion 62B is inserted into the insertion port 67, whereby the arm belt portion holding portion 62 can be detachably attached to the back surface 66 side of the housing portion 60. Between the holding surface 62A and the back surface 66 of the housing portion 60, the folded armband portion 2 can be detachably accommodated. Thereby, when the person to be measured does not use the armband portion 2, the folded armband portion 2 can be easily and reliably stored between the holding surface 62 </ b> A and the back surface 66 of the housing portion 60. it can.

Thus, when the person to be measured does not measure blood pressure, the armband part 2 is held on the back side of the housing part 60, so that the person to be measured is not obstructed by the armband part 2, and FIG. The display content of the display unit 63 such as time and room temperature can be visually confirmed. For this reason, the person to be measured can easily confirm whether or not the temperature is suitable for blood pressure measurement (environmental temperature) by visually observing the display temperature of the display unit 63.
When the person to be measured does not measure blood pressure, the armband portion 2 is held on the back side of the housing portion 60, so that the appearance of the sphygmomanometer 1 can be improved. For this reason, the sphygmomanometer body 10 can be displayed in a living room or the like as a clock when not in use.

As shown in FIG. 2A, an air plug difference provided with an O-ring (not shown) is provided at a lower position of a side surface portion 68 (a left side surface portion facing the front surface of the housing portion 60) 68 of the housing portion 60. A slot 73 is formed. The air plug 6 can be detachably attached to the air plug insertion port 73. In the air plug insertion port 73, the width d1 of the linear upper portion 73A is set larger than the width d2 of the semicircular lower portion 73B in accordance with the shape of the air plug 6. Inside the air plug insertion port 73, insertion holes 73G and 73H are provided.
The air plug 6 is made of plastic, for example, and includes a housing 6A, connecting cylinder portions 6B and 6C, and a connecting guide portion 6F as shown in FIG. The connecting cylinder portions 6B and 6C are formed to protrude in parallel from one surface of the housing 6A. These connecting cylinder portions 6B and 6C are detachably inserted into the insertion holes 73G and 73H of the air plug insertion port 73, respectively. The upper part of the connection guide part 6F is guided and inserted into the upper part 73A of the air plug insertion port 73 shown in FIG. 2A, and the lower part of the connection guide part 6F is the air plug difference shown in FIG. It is inserted into the lower portion 73B of the inlet 73 while being guided.

As a result, the air plug 6 is prevented from being installed upside down with respect to the air plug insertion port 73, and the blood pressure monitor main body 10 side is connected to the ischemic air bladder 14 and the two K sound detecting air bags 50. On the other hand, air is not supplied. The armband portion 2 connected to the air plug 6 has a plurality of sizes, for example, three sizes of large, medium and small, so that the most suitable one can be selected according to the size of the upper arm of the user. It has become.
The air plug 6 is provided not on the front side but on the side of the sphygmomanometer body 10, so that even if the drive pump 110 runs away and the armband part 2 is abnormally pressurized, a complicated electronic circuit or an abnormal time is required. Since the air supply can be cut off by the person to be measured withdrawing the air plug 6 without providing the switch, abnormal pressurization of the armband portion 2 can be avoided very easily.

As shown in FIG. 2B, a speaker 85 and an AC adapter are provided on the side surface 69 (the side opposite to the side surface 68 on which the air plug insertion port 73 is formed) 69 of the housing 60 shown in FIG. A connection hole 86 for connecting the two is provided. By connecting a connection jack 87A of an AC adapter 87 to the connection hole 86, the sphygmomanometer body 10 can be supplied with power from a commercial power source. The connection hole 86 shown in FIG. 2B is completely different from the air plug insertion port 73 shown in FIG. Thereby, it is possible to prevent the air plug 6 from being erroneously inserted into the connection hole 86.
As shown in FIG. 2A, an upper surface 71 provided on the upper surface of the housing 60 projects from the right side toward the front of the housing 60, and a start / stop switch 88 and a function selection key. Various operation buttons such as 400 are arranged side by side.

FIG. 5 is a block diagram of the sphygmomanometer 1 shown in FIG.
As shown in FIG. 5, the air bag 14 for the ischemia of the armband portion 2 passes through the air tube 4, an air filter 130 in the sphygmomanometer body 10, a pressure detection unit (pressure sensor) 140, two drive pumps 110, control It is connected to the valve 111 and the exhaust valve 112. The K sound detection air bag 50 for detecting the K sound signal is connected to the condenser microphone 125 in the blood pressure monitor main body 10 through the air tube 5. The pressure detection unit (pressure sensor) 140 detects the pressure in the armband unit 2. As shown in FIG. 5, by providing two K sound detection air bags 50 (when the arm band portion is attached to the upper arm, the opposing positions are provided in the circumferential direction), the K sound can be accurately detected. The number of K sound detection air bags 50 may be one.
As shown in FIGS. 1 and 5, the arm detection sensor 800 arranged in the armband 2 confirms whether the upper arm T is inserted in the armband 2 as shown in FIG. 1. An infrared sensor, a thermistor, or the like that is a confirmation unit and confirms that the upper arm T has been inserted into the arm band 2 by detecting heat generated by the upper arm T, for example. Further, as the arm detection sensor 800, for example, a light detection sensor can be adopted, and the light detection sensor is an optical coupler having a light emitting element and a light receiving element, and light emitted from a light emitting element such as a light emitting diode is emitted. The light irradiated to the upper arm T inserted into the armband portion 2 and reflected by the upper arm T can be received by a light receiving element such as a photosensor.
As shown in FIGS. 1 and 5, the arm detection sensor 800 is electrically connected to the control unit 120 through an electrical wiring 810. The electrical wiring 810 is disposed so as to be integrated with the air tubes 4 and 5 as shown in FIG. When the arm detection sensor 800 detects that the upper arm T has been inserted into the arm band portion 2, an upper arm insertion confirmation signal AS is sent to the control unit 120. Thereby, the control unit 120 can surely know that the upper arm T has been inserted into the armband unit 2.

The two drive pumps 110 shown in FIG. 5 pressurize the upper arm in the armband portion 2 by supplying air to the air bag 14 for ischemia in the armband portion 2 and the two air bags 50 for detecting K sound. Means. As described above, the two drive pumps 110 are used when the size of the armband portion 2 is large, so that the two drive pumps are driven, and when the size of the armband portion 2 is small, one drive pump is used. In order to supply air to the air bag 14 for ischemia and the two air bags 50 for detecting K sound.
On the other hand, the control valve 111 and the exhaust valve 112 are depressurization means for depressurizing the upper arm that is evacuated and pressurized by removing the air in the ischemic air bag 14 and the two K sound detecting air bags 50 in the armband portion 2. 5 drives two drive pumps 110 according to a command from the control unit 120, and the drive unit 151 drives the control valve 111 and the exhaust valve 112 according to a command from the control unit 120.
The control unit 120 shown in FIG. 5 gives a command to the display unit 63 to display necessary display contents such as temperature display, time display, systolic blood pressure, and systolic blood pressure as shown in FIG. A storage unit 153 and a data memory 154 are connected to the control unit 120. As the display unit 63, a liquid crystal display device, an organic EL device, or the like can be adopted. The control unit 120 includes a microcomputer, and includes a ROM that stores a control program for the entire apparatus and various data, and a RAM that temporarily stores measurement data and various data as a work area.

In the sphygmomanometer main body 10 of FIG. 5, before measuring the blood pressure, a pre-measurement music generation mode for generating music to be heard by the measurement subject in order to make the measurement subject relax, and measuring the blood pressure. And a during-measurement music generation mode for generating music to be heard by the subject in order to put the subject in a relaxed state.
The music data generated in the pre-measurement music generation mode and the music data generated in the in-measurement music generation mode are stored in advance in the storage unit 153 that stores the music data. That is, the storage unit 153 stores music data to be relaxed for the person to be measured before measuring the blood pressure, voice guidance contents to be performed for the person to be measured while measuring the blood pressure, and light music, for example. Are stored in advance.

In the pre-measurement music generation mode, the control unit 120 shown in FIG. 5 plays the music to be heard by the measurement subject through the speaker 85 to make the measurement subject relax before the blood pressure is measured. You can ask the measurer to listen to relaxing music for mental relaxation. In addition, the control unit 120, before measuring the blood pressure in the pre-measurement music generation mode, at a stage before listening to music in order to make the measurement subject relax through the speaker 85, For example, a deep breath suggestion message “Please take a deep breath” can be notified.
Similarly, in the in-measuring music generation mode, the control unit 120 causes the speaker 85 to send voice guidance contents to be performed to the measurement subject and music data such as light music through the speaker 85 while measuring the blood pressure. Thus, it is possible to listen to relaxing music for mentally relaxing the subject and voice guidance contents as necessary. Here, as an example of the voice guidance content that is notified during blood pressure measurement, when the measurement of the minimum blood pressure value and the maximum blood pressure value is started, for example, the speaker 85 “measures the minimum blood pressure value and the maximum blood pressure value”. Can be shed.

The data memory 154 shown in FIG. 5 stores a program for performing a series of operations necessary for blood pressure measurement, and the control unit 120 performs a blood pressure measurement operation according to this program.
In FIG. 5, a start / stop switch 88 and a function selection key 400 as a function selection unit are electrically connected to the control unit 120.
When the medical staff (or the person to be measured) presses the function selection key 400 shown in FIG. 2, the function selection signal SS, the function selection signal SS1, and the function selection signal SS2 shown in FIG. The measurement mode can be selected.
As illustrated in FIG. 7, the measurement mode can be selected from a total of three modes: a forced relaxation mode FRM shown in step SR1, a relaxation mode RM shown in step S1, and a normal measurement mode NM shown in step S20. It has become. The forced relax mode FRM is a first relax mode, and the relax mode RM is also referred to as a second relax mode.

The forced relaxation mode FRM shown in step SR1 shown in FIG. 7 is preferably a mode that can be set by a medical worker, and before the blood pressure is measured, that is, as shown in FIG. Before measuring the blood pressure by pressurizing the arm, the control unit 120 confirms whether or not the subject has passed the upper arm T in the armband portion 2 by using the arm detection sensor 800 and notifies the control unit 120 of it. In this mode, when it can be confirmed that the upper arm T passes through the armband part 2, the measured person can relax the measured person by listening to the melody of the music data for a certain period of time. .
The relaxation mode RM shown in step S1 shown in FIG. 7 is a mode that can be set by a medical worker or a person to be measured, and before the blood pressure measurement, that is, as shown in FIG. In this mode, the subject can be in a relaxed state by listening to the melody of the music data for a certain period of time before T is pressurized and blood pressure is measured.
On the other hand, the normal measurement mode NM of step S20 shown in FIG. 7 is a mode that can be set by a medical worker or a person to be measured. Unlike the forced relaxation mode FRM and the relaxation mode RM, the normal measurement mode NM is set. NM is a mode in which a blood pressure measurement operation is immediately started without playing music and not letting the person to be measured in advance before blood pressure measurement. That is, the normal measurement mode NM is a mode in which the blood pressure measurement operation is performed by directly pressurizing the upper arm T by the armband portion 2 as shown in FIG. 1 without reproducing music.

  The speaker 85 in FIG. 5 is an example of a notification unit for reporting relaxation music and voice guidance content, and is electrically connected to the control unit 120 via the filter 164. The power control unit 160 is electrically connected to the battery 93 and the AC adapter 87 and supplies a predetermined DC voltage to the control unit 120. The power control unit 160, the K sound amplifier 161, and the OSC amplifier 162 are electrically connected to the control unit 120.

The K sound amplifier 161 shown in FIG. 5 amplifies the K sound detected by the condenser microphone 125, which is a preferred example of a microphone, and supplies the amplified K sound to the control unit 120. A music noise removal filter 700 is electrically connected between the condenser microphone 125 and the K sound amplifier 161.
This music noise removal filter 700 is a filter for passing the K sound out of the sound entering the condenser microphone 125 and removing music other than the K sound as noise. That is, from the frequency range of the K sound input to the condenser microphone 125 and the frequency range of the music generated by the speaker 85, the frequency range of the music is removed as noise, and only the frequency range of the K sound is reduced to the K sound amplifier 161. It is designed to pass through to the side. Thereby, the music for relaxation generated by the speaker 85 does not become an obstacle to the detection of the K sound, the K sound can be detected accurately, and an accurate blood pressure measurement can be realized.

  6, in the blood pressure operation by the sphygmomanometer 1 in FIG. 5, when the control unit 120 instructs, the control valve 111 and the two drive pumps 110 in FIG. 5 are operated, and the ischemic air shown in FIG. 5. Air is supplied to the bag 14 to pressurize the upper arm until the time point t1 shown in FIG. 6, and then the control valve 111 is operated to reduce the air pressure in the air bag 14 for ischemia so that the inclination is constant. Go. During this decompression, the control unit 120 detects the maximum blood pressure and the minimum blood pressure, and then operates the exhaust valve 112 to release the air in the air bag 14 for the ischemia and the two air bags 50 for detecting the K sound. It has become.

Next, an example of use operation of the sphygmomanometer 1 having the above-described configuration will be described with reference to FIG.
FIG. 7 is a flowchart showing an example of a usage operation of the sphygmomanometer 1.

When the measurement subject presses the start / stop switch 88 shown in FIGS. 1 and 5 and then presses the function selection key 400 shown in FIG. 2 in step SMO of FIG. 7, the measurement mode can be selected. As the measurement mode, there are a relaxation mode RM shown in step S1, a forced relaxation mode FRM shown in step SR1, and a normal measurement mode NM shown in step S20.
When the medical staff (or the person to be measured) presses the function selection key 400 once and sends the function selection signal SS1 to the control section 120, the control section 120 can select the relaxation mode RM, and the medical staff (or the measurement target). When the function selection signal SS2 is sent to the control unit 120 by the operator) pressing the function selection key 400 twice in a short time, the control unit 120 can select the forced relaxation mode FRM. When the medical staff (or the person to be measured) presses the function selection key 400 for a long time and the function selection signal SS is sent to the control unit 120, the control unit 120 may select the normal measurement mode NM. it can.

In step SM0 in FIG. 7, a medical staff such as a doctor preferably confirms blood pressure measurement results (setting values) recorded in the past of the subject to be measured for blood pressure, In the recorded blood pressure measurement result, it is determined whether or not the blood pressure measurement can be performed in a state where the measurement subject is relaxed.
In step SM1, when the medical worker determines that the measured subject cannot measure blood pressure in a relaxed state based on the result of the previous blood pressure measurement, the medical worker fixes the measurement mode to the forced relaxation mode FRM. Then, the process proceeds to the forced relaxation mode FRM in step SR1. On the other hand, in step SM1, when the medical worker determines that the measurement subject can measure the blood pressure in a relaxed state based on the result of the previous blood pressure measurement, the medical worker sets the measurement mode to the forced relaxation mode FRM. In step S0, the measurement mode can be further selected.

First, in FIG. 7, when a medical worker (or a person to be measured) selects the forced relaxation mode FRM in step SR1 by pressing the function selection key 400 shown in FIG. The process proceeds from SR1 to step SRT. In step SRT and step SR2, as shown in FIG. 1, the presence of the upper arm T is detected in order to confirm whether or not the upper arm T is passed through the armband portion 2.
As shown in FIG. 1, when the upper arm T is inserted into the armband portion 2, the finger of the person to be measured is inserted from the opening portion 11R to the opening portion 11P, so that the armband portion 2 is The blood pressure is prepared for measurement by holding it on the upper arm T above the elbow of the measurer. At this time, the two K-sound detection air bags 50 are preferably positioned closer to the opening 11P side than the intermediate position in the longitudinal direction (axial direction) of the armband portion 2 (not closer to the shoulder side but closer to the fingers). Therefore, one of the two K-sound detection air bags 50 can be applied to the portion corresponding to the artery of the upper arm T. Thereby, the K sound detecting air bag 50 can accurately obtain the K sound from the artery.

In step SR2, when the arm detection sensor 800 detects that the upper arm T has been inserted into the armband portion 2 shown in FIG. 5, the upper arm insertion confirmation signal AS shown in FIG. 800 notifies the control unit 120 that the upper arm T has been inserted into the armband unit 2. When the control unit 120 receives a notification that the upper arm T has been inserted, the process proceeds to step SR3.
However, if the arm detection sensor 800 cannot detect that the upper arm T has been inserted into the armband portion 2, the control unit 120 has not yet inserted the upper arm T into the armband portion 2 in step SR5. Judgment is made and the voice guidance content “please pass through the arm” is notified to the subject through the speaker 85. Accordingly, it is possible to reliably urge the upper arm T to pass through the armband portion 2.

Returning to step SR3 in FIG. 7, the control unit 120 in FIG. 5 notifies the measurement subject through the speaker 85 of a deep breath suggestion message “please take a deep breath”.
Thereby, it is possible to prompt the subject to take a deep breath, and the subject advances to a mentally relaxed state by performing a deep breathing operation an arbitrary number of times according to the deep breath suggestion message. be able to. The subject measures blood pressure by encouraging the subject to take a deep breath and by letting the subject hear a piece of music that the subject can take a deep breath to bring the subject into a mentally relaxed state. Before performing, the transition to a relaxed state can be achieved to achieve rest, blood pressure can be lowered, and autonomic nerve stabilization can be achieved.

Then, after notifying the deep breath suggestion message, the control unit 120 plays an arbitrary music for promoting relaxation through the speaker 85 through the speaker 85 in step SR4 for an arbitrary fixed time, for example, 1 minute.
The music melody for promoting relaxation employs music that allows the subject to take a deep breath in order to put the subject in a relaxed state. For example, “Brams Lullaby” can be adopted.
“Brams' lullaby” is a piece of music that makes it easier for the person to take a deep breath. It completes in a total of 16 bars in a certain period of time, for example, 1 minute, and gives a rhythm of 1 breath (intake + exhaust) every 2 bars. As a result, the person to be measured can perform eight deep breaths per minute, and can be relaxed at a low frequency range of 60 to 100 Hz mainly composed of cello.
The fixed time for reproducing the relaxing music is not limited to 1 minute, and may be, for example, 1 minute to 1 minute 30 seconds, and can be arbitrarily selected. The music that the subject can take a deep breath to bring the subject into a relaxed state is not limited to the “Brams Lullaby” described above, and may be, for example, “Schubert's Ave Maria”.

Accordingly, by prompting the subject to “deep breath” in step SR3, and in order to put the subject in a relaxed state in step SR4, the subject can listen to music that the subject can easily take a deep breath, Before performing measurement of blood pressure according to Step S4 to Step S11, the measurement subject can achieve a rest by moving to a relaxed state, realizing a blood pressure reduction and realizing an autonomic nerve stabilization.
As described above, in order to promote “deep breathing” by the person to be measured in step SR3 of FIG. 7 and to make the person to be measured relaxed in step SR4, a music piece that is easy for the person to be deeply breathed is measured. Then, as shown in step S4 to step S13 of FIG. 7 to be described next, the person to be measured actually measures blood pressure using the sphygmomanometer 1 as shown in FIG. The display unit 63 can display the blood pressure measurement result.

  In step S4 in FIG. 7, blood pressure measurement is started by the sphygmomanometer 1 in FIG. 1, and the upper arm T is pressurized by the armband portion 2 to perform normal blood pressure measurement. When pressurization of the upper arm T is started in order to measure the blood pressure in this way, in step S5, the control unit 120 of FIG. As a result, the measurement subject can listen to music during the blood pressure measurement operation from step S4 to step S11, so that the measurement subject can maintain a relaxed state and can perform accurate blood pressure measurement. In other words, even during measurement of blood pressure, the subject can maintain a mental relaxed state while listening to music. To measure blood pressure accurately.

  In step S6 in FIG. 7, the control unit 120 in FIG. 5 operates the control valve 111 and the two drive pumps 110 to supply air to the air bag 14 for ischemia, and adds the upper arm to the time t1 in FIG. Press. When the pulse disappears in step S7 during the pressurization, the pressurization is stopped in step 8, and in step S9, the control unit 120 operates the control valve 111 to adjust the air pressure in the air bag 14 for ischemia. The pressure is reduced so that the inclination becomes constant.

In step S10, during the decompression, the condenser microphone 125 shown in FIG. 5 detects the Korotkoff sound (K sound) to detect the maximum blood pressure value and the minimum blood pressure value. After detecting the systolic blood pressure value and the diastolic blood pressure value, in step S11, the control unit 120 operates the exhaust valve 112 to evacuate the air in the air bag 14 for ischemia and the two air bags 50 for detecting K sound, and quickly exhausts the air. .
In step S12, the control unit 120 stops the music reproduction operation performed in step S5 through the speaker 85. In step S13, the systolic blood pressure value and the diastolic blood pressure value obtained by the measurement subject can be digitally displayed on the display unit 63 as exemplified in FIG. Thereby, the person to be measured can visually confirm numerical values such as the maximum blood pressure value and the minimum blood pressure value which are displayed largely on the display unit 63.

Further, in step SM1 in FIG. 7, when the medical worker determines that the subject is measuring blood pressure in a relaxed state based on the past measurement results, the medical worker (or the subject) measures. Without fixing the mode to the forced relaxation mode FRM, the measurement mode can be further selected in step S0. Therefore, in step S0 in FIG. 7, when the measurement subject presses the function selection key 400 shown in FIG. 2 once to select the relaxation mode RM in step S1, the process proceeds from step S1 to step S2. In step S <b> 2, the control unit 120 in FIG. 5 notifies the measurement subject through the speaker 85 of a deep breath suggestion message “please take a deep breath”.
Then, after notifying the deep breath suggestion message, the control unit 120 plays music for promoting relaxation to the person to be measured through the speaker 85 in any given time, for example, several minutes.
As described above, the music melody for promoting relaxation employs music that allows the subject to take a deep breath in order to put the subject in a relaxed state, for example, “Brams Lullaby”. be able to.

  In step S4 of FIG. 7, the blood pressure measurement operation is started by the sphygmomanometer 1 of FIG. 1, and the armband part 2 attached to the upper arm T is pressurized at a predetermined pressurization speed to perform normal blood pressure measurement. When pressurization of the armband portion 2 is started to measure the blood pressure in this way, in step S5, the control unit 120 in FIG. 5 reproduces music data that can be further relaxed for the measurement subject through the speaker 85. Shed. As a result, the measurement subject can listen to music during the blood pressure measurement operation from step S4 to step S11, so that the measurement subject can maintain a relaxed state and can perform accurate blood pressure measurement. In other words, even during measurement of blood pressure, the subject can maintain a mental relaxed state while listening to music. To measure blood pressure accurately.

In step S6 in FIG. 7, the control unit 120 in FIG. 5 operates the control valve 111 and the two drive pumps 110 to supply air to the air bag 14 for ischemia, and adds the upper arm to the time t1 in FIG. Press. When the pulse disappears in step S7 during the pressurization, the pressurization is stopped in step 8, and in step S9, the control unit 120 operates the control valve 111 to adjust the air pressure in the air bag 14 for ischemia. The pressure is reduced so that the inclination becomes constant.
In step S10, during the decompression, the condenser microphone 125 shown in FIG. 5 detects the Korotkoff sound (K sound) to obtain the highest blood pressure value (systolic blood pressure) and the lowest blood pressure value (diastolic blood pressure). decide. After determining the systolic blood pressure value and the diastolic blood pressure value, in step S11, the control unit 120 operates the exhaust valve 112 to evacuate the air in the air bag 14 and the two K sound detecting air bags 50, and quickly exhausts the air. .
In step S12, the control unit 120 stops the music reproduction operation performed in step S5 through the speaker 85. In step S13, the systolic blood pressure value and the diastolic blood pressure value obtained by the measurement subject can be digitally displayed on the display unit 63 as exemplified in FIG. Thereby, the person to be measured can visually confirm numerical values such as the maximum blood pressure value and the minimum blood pressure value which are displayed largely on the display unit 63.

Furthermore, in step S0 shown in FIG. 7, when the medical worker (or person to be measured) continues to press the function selection key 400 for a certain period of time or longer, the normal measurement mode NM shown in step S20 can be selected. . When the normal measurement mode NM is selected, unlike the automatic relax mode ARM and the fixed relax mode FRM, there is no message reproduction and music reproduction, and the process directly proceeds to step S4 in FIG.
In step S4 in FIG. 7, blood pressure measurement is started by the sphygmomanometer 1 in FIG. 1, and the upper arm T is pressurized by the armband portion 2 to perform normal blood pressure measurement. When pressurization of the upper arm T is started in order to measure the blood pressure in this way, in step S5, the control unit 120 of FIG. As a result, the measurement subject can listen to music during the blood pressure measurement operation from step S4 to step S11, so that the measurement subject can maintain a relaxed state and can perform accurate blood pressure measurement. In other words, even during measurement of blood pressure, the subject can maintain a mental relaxed state while listening to music. To measure blood pressure accurately.

In step S6 in FIG. 7, the control unit 120 in FIG. 5 operates the control valve 111 and the two drive pumps 110 to supply air to the air bag 14 for ischemia, and adds the upper arm to the time t1 in FIG. Press. When the pulse disappears in step S7 during the pressurization, the pressurization is stopped in step 8, and in step S9, the control unit 120 operates the control valve 111 to adjust the air pressure in the air bag 14 for ischemia. The pressure is reduced so that the inclination becomes constant.
In step S10, during the decompression, the condenser microphone 125 detects the Korotkoff sound (K sound) to detect the maximum blood pressure value and the minimum blood pressure value. After detecting the systolic blood pressure value and the diastolic blood pressure value, in step S11, the control unit 120 operates the exhaust valve 112 to evacuate the air in the air bag 14 for ischemia and the two air bags 50 for detecting K sound, and quickly exhausts the air. .
In step S12, the control unit 120 stops the music reproduction operation performed in step S5 through the speaker 85. In step S13, the systolic blood pressure value and the diastolic blood pressure value obtained by the measurement subject can be digitally displayed on the display unit 63 as exemplified in FIG. Thereby, the person to be measured can visually confirm numerical values such as the maximum blood pressure value and the minimum blood pressure value which are displayed largely on the display unit 63.

  By the way, as already explained, after the internal pressure of the air bag 14 of the armband portion 2 is raised to the maximum blood pressure value or higher to temporarily close the blood vessel, the K sound is gradually reduced by decreasing the internal pressure. This sound signal is detected when the blood pressure becomes lower than the hypertension value and starts to open, and the internal pressure becomes lower than the minimum blood pressure value until the blood vessel occlusion disappears. If the condenser microphone 125 shown in FIG. 5 picks up relaxing music from the speaker 85 as noise during the blood pressure measurement in steps S5 to S11 in FIG. 7, the condenser microphone 125 shown in FIG. The detected K sound and the relaxing music from the speaker 85 pass through the music noise removal filter 700.

However, the music noise removal filter 700 can remove the frequency range of music noise other than the K sound from the sound that enters the condenser microphone 125 only through the frequency range of the K sound. That is, the frequency range of the K sound is 40 Hz to 59 Hz in a preferred example, while the frequency range of music noise (music melody noise) to be removed is a higher frequency range, for example, 60 Hz to 100 Hz. The K sound amplifier 161 shown in FIG. 5 can amplify only the frequency range of the K sound detected by the condenser microphone 125 and supply it to the control unit 120.
In this way, the music noise removal filter 700 removes the frequency range of relaxing music noise other than the K sound through only the frequency range of the K sound, so that the speaker during the blood pressure measurement in steps S5 to S11 of FIG. Even under a situation where relaxing music is flowing from 85, the control unit 120 can improve the accuracy of blood pressure measurement by increasing the detection accuracy of the K sound in steps S9 and S10.

  As described above, from step S6 to step S11, the control unit 120 can simultaneously notify the measurement subject of the voice guidance content in the storage unit 153 and the music data prepared in advance through the speaker 85 during blood pressure measurement. . For example, when the speaker 85 starts measuring the minimum blood pressure value and the maximum blood pressure value, the voice guidance “I am measuring the minimum blood pressure value and the maximum blood pressure value” and music such as relaxing light music prepared in advance. It can also be flown with. Note that the type of relaxing music played in step S3 and the type of relaxing music played in step S5 may be the same or different.

In the embodiment of the sphygmomanometer of the present invention, by setting the forced relaxation mode FRM shown in FIG. 7, the measurement subject is in a relaxed state while the measurement subject has passed the upper arm T through the armband portion 2. The blood pressure measurement cannot be started until In other words, if a medical staff such as a doctor checks the past blood pressure measurement results of the patient being measured and determines that the patient is not measuring blood pressure in a relaxed state, It is possible to make settings so that the person to be measured takes a deep breath and listens to music, and in particular, music playback is not skipped.
In the embodiment of the present invention, since the armband portion 2 and the sphygmomanometer body 10 are separate, the sphygmomanometer body 10 is not impaired without the convenience of being able to measure by simply inserting the upper arm T into the armband portion 2. The blood pressure can be measured in a state where the measurer is correctly stretched and is not subjected to abdominal pressure even when the installation location of the device is away from the subject.

The notification unit is, for example, a speaker 85, and the speaker 85 and the display unit 63 that displays the measured blood pressure value are arranged in the sphygmomanometer main body 10. As a result, the person to be measured can accurately measure blood pressure while listening to music from the speaker 85 on the blood pressure monitor body 10 side in a mentally relaxed state, and the blood pressure measurement result obtained is the blood pressure monitor body 10 side. The display unit 63 can be easily confirmed simply by visual inspection.
A speaker is used as an informing unit for informing relaxation music and voice guidance contents. As a type of speaker, a cone signal speaker that vibrates cone paper, a piezoelectric speaker that vibrates a piezoelectric vibrator, and the like. Can be adopted.

Next, another embodiment of the present invention will be described with reference to FIGS.
FIG. 8 is a perspective view showing the whole of another embodiment of the sphygmomanometer of the present invention, and FIG. 9 is a block diagram showing an electrical configuration example of another embodiment of the sphygmomanometer of the present invention. FIG. 10 is a diagram illustrating an example of a blood pressure measurement operation of a sphygmomanometer according to another embodiment of the present invention.
The sphygmomanometer of another embodiment of the present invention shown in FIG. 8 is different from the sphygmomanometer of the embodiment of the present invention shown in FIG. 1 in the sphygmomanometer of another embodiment of the present invention shown in FIG. The arm detection sensor 800 and the electric wiring 810 shown in No. 1 are not used. Thereby, the structure of the armband part 2 can be simplified, and no electrical wiring is required between the armband part 2 and the sphygmomanometer body 10, so that the structure can be simplified and the cost can be reduced.

  In the forced relaxation mode FRM in the blood pressure measurement operation example of the sphygmomanometer of another embodiment of the present invention shown in FIG. 10, the forced relaxation in the blood pressure measurement operation example of the sphygmomanometer of another embodiment of the present invention shown in FIG. The difference is that step SRT of mode FRM is removed. However, the relaxation mode RM and the normal measurement mode NM and steps S4 to S13 in the blood pressure measurement operation example shown in FIG. 10 are the same as the relaxation mode RM and the normal measurement mode NM and steps S4 to S13 in the blood pressure measurement operation example shown in FIG. Therefore, I will use the explanation.

In FIG. 10, in the forced relaxation mode FRM of step SR1, the arm detection sensor 800 is not used, and in step SR5, the control unit 120 determines that the upper arm T has not yet been inserted into the armband portion 2, Since the voice guidance content “please pass through the arm” is notified to the person to be measured through the speaker 85 and the user is prompted to pass the upper arm T, the person to be measured passes the upper arm T through the armband portion 2. Can be surely encouraged.
Therefore, even if the armband portion 2 is not provided with an arm detection sensor, the person to be measured hears the voice guidance content “please pass the arm” through the speaker 85, and the upper arm T is moved to the armband portion as shown in FIG. 2, for example, as shown in FIG. 9, when the measurement subject presses a confirmation operation unit 470 such as a confirmation button, the confirmation operation unit 470 notifies the control unit 120 of the arm insertion confirmation signal SM. To do.
Thereby, the control unit 120 can confirm that the upper arm T has been passed through the armband portion 2. When the person to be measured passes the upper arm T through the armband portion 2, the measurement operation unit 470 shown in FIG. 9 can be pressed to move from step SR2 to step SR3 in FIG. In step SR3, the control unit 120 of FIG. 5 notifies the subject under measurement through the speaker 85 of a deep breath suggestion message “please take a deep breath”.

After notifying the deep breath suggestion message by voice, the control unit 120 in FIG. 9 plays an arbitrary music for promoting relaxation through the speaker 85 through the speaker 85 in step SR4, for example, for a certain period of time. . Then, at an optimal timing when the person to be measured is relaxed, the routine automatically proceeds to a normal blood pressure measurement operation after step S4, and steps S4 to S13 are executed.
In each of the embodiments of the present invention described above, accurate blood pressure measurement can be performed in such a manner that blood pressure measurement cannot be started until the subject is relaxed in a state where the subject is passing the upper arm through the armband. That is, after the person to be measured passes the upper arm through the armband part 2, the controller 120 automatically plays the music and listens to the person to be measured to prompt a relaxed state, and then the control unit 120 automatically performs an appropriate timing. Since the blood pressure measurement operation can be started and the measurement subject does not need to perform an unnecessary operation before measuring the blood pressure, the measurement subject can accurately measure the blood pressure while maintaining a resting state.

By the way, the present invention is not limited to the above-described embodiments, and various modifications and changes can be made to the present invention, and various modifications can be made within the scope described in the claims.
The armband 2 shown in FIGS. 1 to 3 is made of a flexible material that can be folded. However, the present invention is not limited to this, and the sphygmomanometer according to the present invention includes a handle 2V that is covered with a plastic rigid body 2W as shown in FIG. You may employ | adopt the structure in which the laminated body which has the softness | flexibility of the armband part 2 shown in FIGS. 1-3 is incorporated.
In the illustrated example, the armband portion 2 and the sphygmomanometer body 1 are configured separately, but the sphygmomanometer of the present invention has a structure in which the armband portion 2 and the sphygmomanometer body 1 are integrated. It may be a thing.
Further, in the flowcharts of FIGS. 7 and 10, it is not always necessary to play music after the start of pressurizing the armband. In blood pressure measurement by the oscillometric method, the maximum blood pressure and the minimum blood pressure may be determined between the start of pressurization of the armband and the stop of pressurization of the armband.
