DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings.

[0011] <1> Embodiment 1 1 and 2 are a side view and a front view, respectively, of the blood pressure measurement device 100 according to embodiment 1. In addition, Fig. 3 is a perspective view of the blood pressure measurement device 100 as seen from the upper right, and Fig. 4 is a perspective view of the blood pressure measurement device 100 as seen from the upper left.

[0012] For convenience, in this specification, the front of the blood pressure measurement device 100 shown in FIG. 2 is used as a reference, and the ±X directions in the drawing are defined as the left-right directions of the blood pressure measurement device 100, the ±Y directions as the front-to-back directions of the blood pressure measurement device 100, and the ±Z directions as the up-down directions of the blood pressure measurement device 100.

[0013] The blood pressure measurement device 100 is a so-called arm-in type fully automatic blood pressure monitor. The blood pressure measurement device 100 is roughly divided into a base unit 110 and an upper arm insertion unit 120. The base unit 110 has a shape that allows it to be placed stably on a desk. The upper arm insertion unit 120 is supported by the base unit 110.

[0014] The upper arm insertion section 120 has a cylindrical outer shell 120a. A cuff 11 is provided on the inner peripheral surface of the outer shell 120a. The upper arm insertion section 120 is sized so that the subject's upper arm can be inserted therein. With the subject's arm inserted into the upper arm insertion section 120, the arm is pressurized by the cuff 11. The blood pressure measurement device 100 measures the systolic and diastolic blood pressures, for example, by detecting the appearance and / or disappearance of a pulse using a pressure sensor (not shown) provided in the cuff 11. Note that the method of blood pressure measurement is not limited to this embodiment, and various conventionally known methods may be used.

[0015] An operation / display unit 123 consisting of an operation unit and a display unit is provided on the upper part of the upper arm insertion section 120. In the figure, the operation / display unit 123 is shown in a simplified form, but it actually consists of an operation unit consisting of, for example, operation buttons and a display unit such as a liquid crystal panel.

[0016] FIG. 5 is a block diagram showing the configuration of the blood pressure measurement device 100, mainly related to blood pressure measurement.

[0017] The blood pressure measurement device 100 includes a cuff 11, a control unit 12, a pressure increasing unit 13, a pressure detection unit 14, a memory unit 15, an operation unit 123a, and a display unit 123b. As described above, the cuff 11 is provided on the inner circumferential surface of the outer shell 120a of the upper arm insertion section 120. The operation unit 123a and the display unit 123b correspond to the operation / display unit 123 and are provided on the upper part of the upper arm insertion section 120. The control unit 12, the pressure increasing unit 13, the pressure detection unit 14, and the memory unit 15 are provided within the base unit 110. Note that the locations where the control unit 12, the pressure increasing unit 13, the pressure detection unit 14, and the memory unit 15 are arranged are not limited to within the base unit 110. For example, at least one of the control unit 12, the pressure boosting unit 13, the pressure detection unit 14, and the memory unit 15 may be provided in the upper arm insertion unit 120, or at least one of the control unit 12, the pressure boosting unit 13, the pressure detection unit 14, and the memory unit 15 may be provided outside the blood pressure measurement device 100.

[0018] The cuff 11 is a belt-shaped cloth bag that houses an inflatable inflation bag made of, for example, synthetic rubber, inside it. The cuff 11 is connected to the pressure increasing unit 13 via a flexible tube (hose).

[0019] The control unit 12 includes an arithmetic processing device such as a CPU (Central Processing Unit) and a memory device such as a RAM (Random Access Memory). The control unit 12 executes overall control of the blood pressure measurement device 100 by expanding a program stored in the storage unit 15 into the memory device and executing it with the arithmetic processing device.

[0020] Pressure increasing unit 13 increases the pressure in cuff 11 during blood pressure measurement. In this embodiment, pressure increasing unit 13 has air supply unit 13a and air exhaust unit 13b.

[0021] Air supply unit 13a is a pump that supplies air to cuff 11, thereby increasing the pressure inside cuff 11. Air exhaust unit 13b is a valve that reduces the pressure inside cuff 11 by exhausting air from cuff 11. For example, blood pressure is measured by controlling air supply and exhaust in the following order: pressurization (air supply by the pump of air supply unit 13a) → blood flow interruption (for example, stopping the pump at an inflation value of 200 mmHg) → exhaust (slowly reducing the pressure by throttling and opening the valve of exhaust unit 13b) → appearance of pulse → disappearance of pulse → exhaust (rapidly reducing the pressure by fully opening the valve of exhaust unit 13b).

[0022] The pressure detection unit 14 is a pressure-electricity conversion sensor using, for example, a piezoelectric element, and detects the pressure inside the cuff 11 and outputs a detection signal (electrical signal) indicating the detected pressure to the control unit 12 via an AD converter (not shown). The control unit 12 detects the appearance and / or disappearance of a pulse based on this detection signal, and measures the systolic blood pressure and diastolic blood pressure based on this.

[0023] After measuring the systolic blood pressure and the diastolic blood pressure, the control unit 12 stores the systolic blood pressure and the diastolic blood pressure values ​​as measurement data in the memory unit 15. When the blood pressure measurement is completed, the control unit 12 discharges all the air from the cuff 11.

[0024] The blood pressure measurement method employed in the blood pressure measurement device 100 is not limited to this, and various known blood pressure measurement methods can be applied.

[0025] In addition to this configuration, as shown in FIGS. 6 to 8, in the blood pressure measuring device 100 of this embodiment, the upper arm insertion section 120 is supported by the base section 110 so that the upper arm insertion direction (L0, L1, L2 in the figures) can be rotated both clockwise (the direction shown in FIG. 8) and counterclockwise (the direction shown in FIG. 7) from the horizontal direction (L0 in the figures).

[0026] As a result, the blood pressure measurement device 100 is capable of measuring blood pressure by inserting the arm from either the left or right direction into the upper arm insertion section 120. Furthermore, the subject can measure blood pressure by inserting their right arm into the upper arm insertion section 120 from the front of the blood pressure measurement device 100, or by inserting their left arm into the upper arm insertion section 120 from the front of the blood pressure measurement device 100.

[0027] Note that θ1 shown in Fig. 7 is the maximum rotation angle in the counterclockwise direction, and θ2 shown in Fig. 8 is the maximum rotation angle in the clockwise direction. In this embodiment, the maximum rotation angle in the counterclockwise direction θ1 is equal to the maximum rotation angle in the clockwise direction θ2. In other words, the upper arm insertion section 120 can rotate at the same angle in the clockwise direction as it can rotate at the same angle in the counterclockwise direction.

[0028] 9 to 12 are cross-sectional views showing examples of the configuration of a support structure that supports upper arm insertion section 120 so that the upper arm insertion direction can be rotated both clockwise and counterclockwise from the horizontal direction as described above.

[0029] 9 and 10 show a first example of the support structure. A rotation shaft 124 is formed at the bottom of the upper arm insertion section 120. The rotation shaft 124 is formed at the center position in the X direction and extends in the Y direction. The rotation shaft 124 is rotatably engaged with a bearing section formed in the base section 110. The base section 110 is provided with two coil springs 111a and 111b.

[0030] As a result, when upper arm insertion section 120 is rotated counterclockwise from the neutral position shown in Fig. 9 as shown in Fig. 10 (in practice, when the right arm of the subject is inserted into upper arm insertion section 120, the state shown in Fig. 10 is reached), coil spring 111a biases the underside of upper arm insertion section 120. As a result, when the right arm is removed from upper arm insertion section 120, upper arm insertion section 120 returns to the neutral position shown in Fig. 9. Although not shown, when the left arm of the subject is inserted into upper arm insertion section 120, upper arm insertion section 120 is rotated clockwise from the neutral position, and when the left arm is removed from upper arm insertion section 120, coil spring 111b returns it to the neutral position.

[0031] 11 and 12 show a second example of the support structure. Two support shafts 125a and 125b are formed at the bottom of the upper arm insertion section 120. The support shafts 125a and 125b extend parallel to each other in the Y direction. The support shafts 125a and 125b are slidably engaged with guide grooves 112a and 112b formed in the base section 110.

[0032] As a result, support shafts 125a, 125b move along guide grooves 112a, 112b, allowing upper arm insertion section 120 to move from the neutral position shown in Fig. 11 to a state rotated counterclockwise as shown in Fig. 12, or to a state rotated clockwise (not shown). Note that in the configuration examples of Figs. 11 and 12, unlike the configuration examples of Figs. 9 and 10, upper arm insertion section 120 cannot automatically return to the neutral position and must be returned manually.

[0033] Next, the relationship between the blood pressure measurement device 100 of this embodiment and the subject 1 will be described with reference to FIGS.

[0034] 13 shows the relationship between the blood pressure measurement device 100 and the subject 1 before blood pressure measurement begins. The blood pressure measurement device 100 is placed on a desk, and the subject 1 sits in a position facing the blood pressure measurement device 100.

[0035] FIG. 14 shows a state in which the right arm is inserted into the upper arm insertion section 120 of the blood pressure measurement device 100. At this time, the upper arm insertion section 120 is rotated counterclockwise from the horizontal. FIG. 15 shows a state in which the left arm is inserted into the upper arm insertion section 120 of the blood pressure measurement device 100. At this time, the upper arm insertion section 120 is rotated clockwise from the horizontal. Here, as can be seen from FIGS. 14 and 15, blood pressure is measured in a positional relationship in which the subject 1 sits in front of the blood pressure measurement device 100 and the blood pressure measurement device 100 is located to the side of the arm to be inserted.

[0036] FIG. 16 shows an insertion state in another usage pattern. This figure shows an example in which the blood pressure measurement device 100 is installed so that the side of the device faces the subject 1. As can be seen from the figure, this causes the subject 1 to lean forward when inserting their arm into the upper arm insertion section 120, making it difficult for them to assume a natural posture suitable for blood pressure measurement. This may adversely affect the results of blood pressure measurement. The blood pressure measurement device 100 of this embodiment is installed so that the subject 1 sits in front of the device, thereby preventing a decrease in the accuracy of blood pressure measurement results caused by the subject 1 leaning forward, as shown in FIG. 16.

[0037] In most conventional blood pressure measurement devices 100, blood pressure is measured in a position where the opening for inserting the arm faces the subject 1, as shown in FIG. 16 , which raises concerns about the adverse effects of posture on blood pressure measurement. In other words, when the opening for inserting the arm faces the subject 1, the subject 1 tends to insert their arm all the way in. As a result, the subject 1 may lean forward, which may result in an error in blood pressure measurement. In particular, conventional arm-in type blood pressure measurement devices often have elbow rests, which increases the possibility that the subject may lean forward, raising concerns about the adverse effects of posture on blood pressure measurement results.

[0038] In contrast, the blood pressure measurement device 100 of the present embodiment allows the subject 1 to measure blood pressure in a natural and comfortable posture, as shown in FIGS. 14 and 15, and therefore blood pressure measurement can be performed with little influence from posture.

[0039] In addition, in the blood pressure measurement device 100 of this embodiment, the subject 1 only needs to change the orientation of his or her body when measuring the right arm or the left arm, and does not need to change his or her sitting position, which makes it possible to save space.

[0040] In other words, with conventional arm-in type blood pressure measurement devices, when there are multiple subjects whose right and left arms are to be measured, it is necessary to move the position of the device or the chair. With blood pressure measurement device 100 of the present embodiment, this is not necessary, and space can be saved.

[0041] Furthermore, with conventional arm-in type blood pressure measuring devices, it is necessary to leave space for a wheelchair to sit on both sides of the device when installing the device. However, with blood pressure measuring device 100 of the present embodiment, it is only necessary to leave space in front of the device, which saves space. Furthermore, in the case of a wheelchair, if the wheelchair is placed next to the front of the device, measurement can be performed with either arm, or more specifically, with either the left or right arm closest to the device, depending on the orientation of the device.

[0042] As described above, according to this embodiment, the blood pressure measuring device 100 has a cylindrical outer shell 120a with the cuff 11 provided on its inner circumferential surface, and is equipped with an upper arm insertion section 120 into which the arm of the subject 1 can be inserted, and a base section 110 that supports the upper arm insertion section 120. The upper arm insertion section 120 is supported by the base section 110 so that the upper arm insertion direction (L0, L1, L2 in FIGS. 6 to 8) can be rotated in both the clockwise direction (the direction shown in FIG. 8) and the counterclockwise direction (the direction shown in FIG. 7) from the horizontal direction (L0 in FIGS. 6 to 8).

[0043] This makes it possible to realize an arm-in type blood pressure measuring device 100 which is advantageous in terms of the posture and position of the subject 1 during measurement and allows the subject 1 to be measured in a comfortable and natural posture.

[0044] <2> Embodiment 2 FIG. 17 is a front view of a blood pressure measurement device 200 according to the second embodiment, and FIG. 18 is a perspective view showing the blood pressure measurement device 200 according to the second embodiment and a subject 1.

[0045] Compared to the blood pressure measurement device 100 of the first embodiment, the blood pressure measurement device 200 of the present embodiment has guide portions 201 and 202. The blood pressure measurement device 200 also has cutout portions 203 and 204. Other configurations of the blood pressure measurement device 200 are the same as those of the blood pressure measurement device 100.

[0046] Guide portion 201 protrudes outward from outer shell 120a at first open end 121 of outer shell 120a to guide the inserted arm. Guide portion 202 protrudes outward from outer shell 120a at second open end 122 of outer shell 120a to guide the inserted arm.

[0047] The guide portions 201 and 202 are formed at approximately the center in the up-down direction of the outer shell 120. As can be seen from Fig. 18, the guide portions 201 and 202 are formed on the far side as seen from the subject 1. The surfaces of the guide portions 201 and 202 that come into contact with the arms, in other words, the front surfaces of the guide portions 201 and 202, are curved in the same manner as the inner peripheral surface of the outer shell 120a.

[0048] This allows the subject 1 to smoothly insert his / her arm into the upper arm insertion section 120 along the guide sections 201 and 202.

[0049] Furthermore, whether the left arm or the right arm should be inserted is displayed on the front of the guide portions 201, 201. This allows the subject 1 to easily visually recognize which arm (left or right) should be inserted and from which direction in the upper arm insertion portion 120.

[0050] The notch 203 is formed in a position on the front side of the first opening end 121 of the outer shell 120a as seen from the subject 1. The notch 204 is formed in a position on the front side of the second opening end 122 of the outer shell 120a as seen from the subject 1. In other words, the notch 203 is formed in a position on the front side of the blood pressure measurement device 100 of the first opening end 121 of the outer shell 120a. The notch 204 is formed in a position on the front side of the blood pressure measurement device 100 of the second opening end 122 of the outer shell 120a. In other words, the notch 203 has a curved shape and is formed in a central region in the up-down direction of the first opening end 121 of the outer shell 120a. Similarly, the notch 204 has a curved shape and is formed in a central region in the up-down direction of the second opening end 122 of the outer shell 120a. By forming the notches 203 and 204, the subject 1 can insert his / her arm into the upper arm insertion portion 120 more smoothly.

[0051] As shown in Fig. 19, the guide units 201 and 202 may be configured to be detachable from the outer shell 120a. With this configuration, by removing the guide units 201 and 202 from the outer shell 120a, it becomes possible to use the blood pressure measurement device 200 by placing the blood pressure measurement device 200 so that its side faces the subject 1, as shown in Fig. 20, for example. However, doing so may cause the subject 1 to lean forward, as described in Fig. 16, which may adversely affect the results of blood pressure measurement. However, making the guide units 201 and 202 detachable from the outer shell 120a is effective in terms of increasing the variety of uses of the blood pressure measurement device 200.

[0052] Furthermore, as shown in FIGS. 21 and 22, movable members 201a and 202b that move when contacted by the body of the subject 1 may be provided at the respective ends of the guide units 201 and 202 in the insertion direction, and the arm insertion state may be detected based on the state of the movable members 201a and 202b. The movable members 201a and 202b are biased by springs (not shown) to a protruding state as shown in FIG. 21, and when pressed toward the upper arm insertion section 120, they are retracted as shown in FIG. 22. FIG. 21 is a front view of the blood pressure measurement device 200 showing the movable members 201a and 202a in an unretracted state, and FIG. 22 is a front view of the blood pressure measurement device 200 showing the movable members 201a and 202a in a retracted state. The upper arm insertion section 120 is provided with a switch (not shown) that is turned on when the movable members 201a and 201b are retracted (FIG. 22).

[0053] FIG. 23 is a perspective view showing a state in which the wrong arm is inserted into blood pressure measurement device 200. Incidentally, the state in which the correct arm is inserted is shown in, for example, FIG. 35, in which guide units 201 and 202 are positioned on the outside of the arm. When the wrong arm is inserted as shown in FIG. 23, guide units 201 and 202 are positioned on the inside of the arm, and either movable member 201a or 202a is pressed by the armpit of subject 1. FIG. 24 is an enlarged perspective view showing a state in which movable member 201a is pressed by the armpit of subject 1.

[0054] If either of movable members 201a, 202a is pressed to the retracted state and a switch (not shown) corresponding to the retracted movable member 201a, 201b is turned on, an error message or an alarm sound can be output, allowing the subject 1 to recognize that he or she has inserted his or her arm in the wrong direction into the blood pressure measurement device 200. As a result, the subject 1 can be prompted to reinsert his or her arm in the correct direction.

[0055] <3> Embodiment 3 FIG. 25 is a perspective view showing the configuration of a blood pressure measurement device 300 according to the third embodiment, and FIG. 26 is a perspective view showing the blood pressure measurement device 300 according to the third embodiment when in use.

[0056] Compared to blood pressure measurement device 100 of embodiment 1, blood pressure measurement device 300 of the present embodiment has an elbow rest 301. Other configurations of blood pressure measurement device 300 are the same as those of blood pressure measurement device 100.

[0057] Armrest 301 has horizontal surface 301a and inclined surface 301b that slopes upward from horizontal surface 301a. Armrest 301 can be attached to base 110 from either the left or right side of base 110. That is, although armrest 301 is attached to the left side of base 110 in Figures 25 and 26, armrest 301 can also be removed from the left side of base 110 and attached to the right side of base 110.

[0058] 26, when the blood pressure measurement device 200 is installed so that the side of the blood pressure measurement device 300 faces the subject 1, the subject 1 can place his / her arm on the elbow rest 301, which reduces the amount of arm insertion. As a result, the amount of forward lean of the subject 1 can be reduced.

[0059] <4> Embodiment 4 27 and 28 are perspective views provided for explaining embodiment 4. This embodiment proposes providing a rotation detection unit that detects whether upper arm insertion section 120 is rotating clockwise or counterclockwise.

[0060] Fig. 27 shows an example in which an acceleration sensor 401 is provided as the rotation detection unit, and Fig. 28 shows an example in which a ball sensor 402 is provided as the rotation detection unit. The ball sensor 402 detects the direction of tilt based on the position where the ball has rolled. Figs. 27 and 28 show a state in which the operation and display unit 123 has been removed. In other words, the acceleration sensor 401 or the ball sensor 402 is provided below the operation and display unit 123.

[0061] In this way, by providing a rotation detection unit that detects whether upper arm insertion section 120 is rotating clockwise or counterclockwise, it becomes possible to detect whether the right arm or left arm is inserted into upper arm insertion section 120 to measure blood pressure. For example, as shown in Figures 27 and 28, if upper arm insertion section 120 is rotating counterclockwise, it can be detected that blood pressure is being measured on the right arm.

[0062] As a result, it is possible to record whether the blood pressure measurement was taken from the left or right arm. For example, by measuring the blood pressure of both the left and right arms and detecting the difference between the measured values, it is possible to determine which arm has a disease.

[0063] <5> Fifth embodiment In this embodiment, as described in embodiment 1 and the like, a suitable configuration example of operation / display unit 123 is presented for the case where upper arm insertion section 120 is supported by base section 110 so as to be rotatable in both clockwise and counterclockwise directions from the horizontal direction.

[0064] 29 to 34 are perspective views showing configuration examples of the operation and display unit 123 in this embodiment.

[0065] The configurations in Figures 29 to 33 have in common that the operation / display unit 123 has a shape that is symmetrical when viewed from the first opening end side of the outer shell 120a and when viewed from the second opening end side of the outer shell 120a.

[0066] Here, when subject 1 inserts his / her left arm into upper arm insertion section 120, he / she will see operation / display section 123 from the left side, and when he / she inserts his / her right arm, he / she will see operation / display section 123 from the right side. In this case, operation / display section 123 has a shape that is symmetrical when viewed from first opening end 121 of outer shell 120a and when viewed from second opening end 122 of outer shell 120a, so subject 1 can operate operation / display section 123 with the same feeling and can see the same displayed image when inserting his / her left arm and when inserting his / her right arm.

[0067] The operation / display unit 123 in FIG. 29 is an example in which a display unit 123b is arranged in the center in the left-right direction, and operation units 123a are arranged on both sides of the display unit 123b.

[0068] The operation / display unit 123 in FIG. 30 is an example in which an operation unit 123a is arranged in the center in the left-right direction, and display units 123b are arranged on both sides of it.

[0069] The operation / display unit 123 in FIG. 31 is an example in which the outer shape is triangular, and similar operation units 123a and display units 123b are arranged on the two sides of the triangle.

[0070] The operation / display unit 123 in FIG. 32 has a trapezoidal outer shape, and is an example in which an operation unit 123a is arranged on the top surface and display units 123b are arranged on the left and right surfaces.

[0071] The operation / display unit 123 in Figure 33, like Figure 31, has a triangular outer shape, and is an example in which similar operation units 123a and display units 123b are arranged on two sides, with the display units 123b on both sides being configured using a single organic EL display or the like.

[0072] FIG. 34 shows an example in which a flexible display unit 123b such as an organic EL display is provided along the outer circumferential surface of the upper arm insertion section 120. In FIG.

[0073] Fig. 35 is a perspective view showing a state in which blood pressure measurement is performed using a blood pressure measurement device having operation and display unit 123 of Fig. 29. Fig. 36 is a perspective view showing a state in which blood pressure measurement is performed using a blood pressure measurement device having operation and display unit 123 of Fig. 31.

[0074] Furthermore, display unit 123b may change the display orientation depending on whether the arm is inserted from first opening end 121 of outer shell 120a or from second opening end 122 of outer shell 120a. In other words, the display on display unit 123b may be switched to a display that is easy to view from the left side when the left arm is inserted, and to a display that is easy to view from the right side when the right arm is inserted.

[0075] <6> Sixth embodiment In this embodiment, as described in embodiment 1 and the like, a suitable configuration example of display unit 123b is presented for the case where upper arm insertion section 120 is supported by base section 110 so as to be rotatable in both clockwise and counterclockwise directions from the horizontal direction.

[0076] 37 and 38 are perspective views showing configuration examples of the display unit 123b in this embodiment.

[0077] A base 501 that supports display unit 123b is provided on the upper part of upper arm insertion section 120. Display unit 123b is rotatably attached to base 501 via rotation shaft 502. Specifically, display unit 123b is attached to base 501 so that it hangs down from base 501 with the display surface facing upward.

[0078] That is, display unit 123b is attached to upper arm insertion section 120 so that the display surface remains horizontal even when upper arm insertion section 120 is rotated both clockwise and counterclockwise from the horizontal direction.

[0079] This allows the subject 1 to easily view the display surface regardless of the rotational position of the upper arm insertion section 120. Specifically, for example, whether before blood pressure measurement as shown in Fig. 39 or during blood pressure measurement as shown in Fig. 40, the display surface of the display unit 123b always faces upward, making it easier for the subject 1 to view the display surface compared to when the display surface tilts in response to rotation.

[0080] <7> Embodiment 7 41 and 42 are perspective views showing the configuration of the seventh embodiment.

[0081] In this embodiment, it is proposed to further provide a rotation support member 601 that supports the base unit 110 so that it can rotate freely in the horizontal plane.

[0082] The rotation support member 601 is placed on a desk. The base 110 is attached to the rotation support member 601 so as to be rotatable in the horizontal plane. This allows the base 110 and the upper arm insertion section 120 to be rotatable in the horizontal plane, so that the upper arm insertion section 120 can be rotated in the horizontal plane depending on the sitting position of the subject 1 and the arm insertion direction. This allows the subject 1 to insert his or her arm into the upper arm insertion section 120 more smoothly.

[0083] <8> summary As described above, the blood pressure measurement device of the present disclosure can provide the following effects.

[0084] -Blood pressure can be measured smoothly on either the left or right arm without moving the blood pressure measuring device or chair.

[0085] -The subject can take a posture that does not lean forward, improving the accuracy of blood pressure measurements.

[0086] The armrest can be eliminated, allowing the subject to measure blood pressure in a natural position without having to turn their palms up. However, turning the palms up would mean twisting the arm, which is not a relaxed position.

[0087] When measuring the right arm or the left arm, the subject only needs to change their body position; there is no need to change their sitting position. This eliminates the need to provide space for the subject on the left and right sides of the blood pressure measurement device. In addition, since the subject's arm extends to the left and right of the blood pressure measurement device, the space required in the front-to-back direction of the blood pressure measurement device is reduced. This means that the back side of the desk on which the blood pressure measurement device is installed can be placed against the wall.

[0088] The above-described embodiments are merely examples of specific embodiments of the present invention, and the technical scope of the present invention should not be construed as being limited by these embodiments. In other words, the present invention can be embodied in various forms without departing from the gist or main characteristics thereof.

[0089] In the above embodiment, the case where operation / display unit 123 is provided in upper arm insertion unit 120 has been described, but this is not limiting. The operation unit and display unit may be provided in a location separate from upper arm insertion unit 120, for example.

[0090] In the above embodiment, the pressure generated by the cuff 11 is described as being generated using a pump and an air bag, but this is not limiting. For example, the pressure generated by the cuff 11 may be generated by wrapping the cuff 11 around the patient using a motor or gears. [Industrial Applicability]

[0091] The blood pressure measurement device of the present disclosure is widely applicable to arm-in type blood pressure measurement devices. [Explanation of symbols]
