[0004] The blood pressure measuring device of Patent Document 1 has room for improvement in accurately measuring both blood pressure values and electrocardiogram waveforms.

[0005] An object of the present disclosure is to provide a blood pressure monitor main body that can more accurately measure blood pressure values and electrocardiogram waveforms.

[0006] The blood pressure monitor main body according to one aspect of the present disclosure includes a housing and a first measurement electrode and a second measurement electrode provided on the housing respectively. The housing includes a bottom surface, a front surface, a rear surface, a first side surface, and a second side surface that extend in a first direction intersecting the bottom surface.

[0009] An example of this disclosure is described below with reference to the accompanying drawings. The following description is essentially illustrative and does not limit this disclosure, its applications, or its uses. The accompanying drawings are schematic, and the proportions of dimensions, etc., may differ between the illustrated configuration and the actual product. In the following description, terms such as "approximately" or "about" mean that the values ​​or shapes that follow these terms include an acceptable margin of error as determined by a person skilled in the art.

[0010] In one aspect of this disclosure, the blood pressure monitor body 10, together with a cuff 20 for compressing the area of ​​the person to be measured, constitutes part of the blood pressure monitor 1. The blood pressure monitor 1 has the function of measuring the blood pressure value and electrocardiogram waveform of the person to be measured.

[0011] As shown in Figure 1, the blood pressure monitor body 10 comprises a housing 30 and a first measuring electrode 41 and a second measuring electrode 42 provided in the housing 30, respectively. In this embodiment, the blood pressure monitor body 10 comprises a processor 11, a storage unit 12, a communication unit 13, a display unit 14, an electrocardiogram waveform detection circuit 15, a regulator 16, a pressure sensor 61, a control valve 62, a rotary pump 63, a communication switch 17, a start / stop switch 18, a power supply unit 19, a first reference electrode 51, and a second reference electrode 52. The processor 11, storage unit 12, communication unit 13, electrocardiogram waveform detection circuit 15, regulator 16, pressure sensor 61, control valve 62, and rotary pump 63 are each provided inside the housing 30. The display unit 14 is provided in the housing 30 in a state where it can display information to the person being measured (see Figures 2 to 4). The communication switch 17 and the start / stop switch 18 are each provided in the housing 30 in a state where they can be operated by the person being measured (see Figures 2 to 4).

[0012] The processor 11 includes, for example, a CPU, MPU, GPU, DSP, FPGA, or ASIC. The processor 11 controls the blood pressure monitor body 10 based on a program stored in the memory unit 12. For example, the processor 11 displays necessary information in the display unit 14, initiates communication between the blood pressure monitor body 10 and a portable information terminal such as a smartphone in response to the operation of the communication switch 17 or the start / stop switch 18, and starts measuring the blood pressure value and electrocardiogram waveform of the person being measured.

[0013] The storage unit 12 includes, for example, an internal recording medium or an external recording medium, and is configured to store, for example, a program for controlling the blood pressure monitor body 10, and the measured blood pressure values ​​and electrocardiogram waveforms of the person being measured. The internal recording medium includes non-volatile memory, etc. The external recording medium includes a hard disk drive (HDD), a solid-state drive (SSD), or an optical disc drive, etc. The communication unit 13 consists of, for example, a communication circuit or communication module for sending and receiving data with an external device, including a personal information terminal.

[0014] The display unit 14 includes, for example, a display and is configured to display data relating to the measured blood pressure values ​​and electrocardiogram waveforms of the subject.

[0015] The electrocardiogram waveform detection circuit 15 is configured to measure the electrocardiogram waveform of a person being measured when they are in contact with the first measuring electrode 41 and the second measuring electrode 42. The first measuring electrode 41 is configured to contact the person being measured via their left hand, and the second measuring electrode 42 is configured to contact the person being measured via their right hand. In this embodiment, when the person being measured contacts the first measuring electrode 41, the first reference electrode 51 also contacts the person being measured at the same time, and when the person being measured contacts the second measuring electrode 42, the second reference electrode 52 also contacts the person being measured at the same time. When both hands of the person being measured are in contact with the first measuring electrode 41 and the second measuring electrode 42, the electrical signals flowing through the person's heart are extracted, and the electrocardiogram waveform is measured. When both hands of the person being measured are in contact with the first reference electrode 51 and the second reference electrode 52, the potential of the person being measured becomes the same potential as ground, and noise that may be included in the electrocardiogram waveform is canceled out.

[0016] The regulator 16 is configured to boost the DC voltage supplied from the power supply unit 19 (for example, a battery) and output it to the rotary pump 63.

[0017] The pressure sensor 61 is configured to detect the pressure inside the cuff 20. The control valve 62 is configured to exhaust the air inside the cuff 20. The rotary pump 63 is configured to supply air to the inside of the cuff 20.

[0018] The cuff 20 is configured to be attachable to, for example, the upper arm of the person being measured (an example of a measurement site) and is connected to the blood pressure monitor body 10 via a tube 70 (see Figures 6 and 7).

[0019] When the start / stop switch 18 is operated with the cuff 20 attached to the subject's upper arm, the rotary pump 63 is driven to supply air to the cuff 20, compressing the subject's upper arm with the cuff 20. While the rotary pump 63 is supplying air to the cuff 20, the internal pressure of the cuff 20 is detected and output by the pressure sensor 61. The processor 11 calculates the systolic blood pressure, diastolic blood pressure, and pulse rate from the output of the pressure sensor 61 based on a blood pressure calculation algorithm (e.g., oscillometric method).

[0020] As shown in Figures 2 to 6, the housing 30 includes a bottom surface 31 and a front surface 32, a rear surface 33, a first side surface 34, and a second side surface 35, which extend in a first direction (for example, the Z direction) intersecting the bottom surface 31. In this embodiment, the housing 30 has a substantially elliptical cylindrical shape with the first direction Z as its major axis and includes a top surface 36 that is spaced apart from the bottom surface 31 in the first direction Z.

[0021] The bottom surface 31 is the surface that faces the table 300 (see Figure 7) on which the blood pressure monitor body 10 is placed, and as shown in Figures 3 and 5, it is provided with a plurality of protrusions 311.

[0022] The front surface 32 and the rear surface 33 are spaced apart in a second direction (e.g., the Y direction) that intersects the first direction Z. In this embodiment, each of the front surface 32 and the rear surface 33 extends substantially parallel to a third direction (e.g., the X direction) that intersects the first direction Z and the second direction Y.

[0023] In this embodiment, as shown in Figure 5, when viewed along the third direction X, the front surface 32 and the rear surface 33 are inclined such that they move away from the bottom surface 31 in the first direction Z and approach each other in the second direction Y. As shown in Figure 6, the rear surface 33 includes a connecting portion 71 to which the tube 70 is connected. Of the two ends of the tube 70 in the direction in which the tube 70 extends, one end is connected to the cuff 20, and the other end of the tube 70 is connected to the connecting portion 71. For example, the connecting portion 71 is located approximately in the center of the rear surface 33 in the third direction X and is located closer to the bottom surface 31 than to the top surface 36 in the second direction Y.

[0024] The first side surface 34 and the second side surface 35 are spaced apart in the third direction X. As shown in Figure 4, the first side surface 34 and the second side surface 35 are symmetrically positioned with respect to a center line CL that passes through the center of the housing 30 in the third direction X and extends along the second direction Y when viewed along the first direction Z. Each of the first side surface 34 and the second side surface 35 is curved to project in the second direction Y and away from the center line CL.

[0025] In this embodiment, as shown in Figure 3, the first side surface 34 and the second side surface 35 are inclined such that they move away from the bottom surface 31 in the first direction Z and approach each other in the third direction X. The angle θ1 of the front surface 32 and the rear surface 33 with respect to the bottom surface 31 is, for example, about 4 degrees. As shown in Figure 4, each of the first side surface 34 and the second side surface 35 has a substantially semi-circular shape when viewed along the first direction Z, and both ends are connected to the front surface 32 and the rear surface 33, respectively. The distance between the first side surface 34 and the second side surface 35 in the third direction X is longer than the distance between the front surface 32 and the rear surface 33 in the second direction Y.

[0026] As shown in Figures 2 to 5, the first measuring electrode 41 is provided on the first side surface 34, and the second measuring electrode 42 is provided on the second side surface 35. Each of the first measuring electrode 41 and the second measuring electrode 42 is located closer to the front surface 32 than to the rear surface 33 when viewed along the first direction Z (see Figures 4 and 5). With the front surface 32 facing the person being measured, the first measuring electrode 41 is configured to be able to contact the carpal area of ​​the person's left hand, and the second measuring electrode 42 is configured to be able to contact the carpal area of ​​the person's right hand. The carpal area is the base of the person's hand, including the palm. The carpal area of ​​the person's hand is usually less dry and thicker than the fingers, so the contact resistance when the first measuring electrode 41 and the second measuring electrode 42 come into contact is suppressed, and a stable electrocardiogram waveform can be obtained.

[0027] The first measuring electrode 41 and the second measuring electrode 42 are configured such that when various subjects with different hand sizes hold the blood pressure monitor body 10 with both hands, the carpal portion of the subject's hands naturally comes into contact with the first measuring electrode 41 and the second measuring electrode 42. For example, the first measuring electrode 41 is positioned in a visible location when viewed from the front 32 along the second direction Y on the first side surface 34, and the second measuring electrode 42 is positioned in a visible location when viewed from the front 32 along the second direction Y on the second side surface 35 (see Figures 3 and 6). The first measuring electrode 41 protrudes from the first side surface 34, and the second measuring electrode 42 protrudes from the second side surface 35 (see Figures 3 to 5). The amount of protrusion from each side surface of the first measuring electrode 41 and the second measuring electrode 42 is set in the range of 1.5 mm to 3.5 mm, for example. For example, the first measuring electrode 41 and the second measuring electrode 42 are positioned symmetrically with respect to the center line CL when viewed along the first direction Z (see Figure 4), but are not limited to this.

[0028] In this embodiment, a first reference electrode 51 is provided on the first side surface 34, and a second reference electrode 52 is provided on the second side surface 35. When the front surface 32 is facing the person being measured, the first reference electrode 51 is configured to be able to contact the wrist of the person's left hand together with the first measuring electrode 41, and the second reference electrode 52 is configured to be able to contact the wrist of the person's right hand together with the second measuring electrode 42. For example, as shown in Figure 5, the first reference electrode 51 is smaller than the first measuring electrode 41 and is positioned adjacent to the first measuring electrode 41 with a gap in the first direction Z. As an example, when viewed along the third direction X, the dimension of the first measuring electrode 41 in the first direction Z is larger than that of the first reference electrode 51, but this is not limited to this. The second reference electrode 52 has the same configuration as the first reference electrode 51. That is, the second reference electrode 52 is smaller than the second measuring electrode 42 and is positioned adjacent to the second measuring electrode 42 with a gap in the first direction Z. As an example, when viewed along the third direction X, the second measuring electrode 42 has a larger dimension in the first direction Z than the second reference electrode 52, but this is not limited to this. The first measuring electrode 41 is located further from the bottom surface 31 than the first reference electrode 51 in the first direction Z, and the second measuring electrode 42 is located further from the bottom surface 31 than the second reference electrode 52 in the first direction Z.

[0029] Similar to the first measuring electrode 41 and the second measuring electrode 42, the first reference electrode 51 protrudes from the first side surface 34, and the second reference electrode 52 protrudes from the second side surface 35 (see Figures 3 to 5). The amount of protrusion from each side surface of the first reference electrode 51 and the second reference electrode 52 is set, for example, in the range of 1.5 mm to 3.5 mm. As an example, the first reference electrode 51 and the second reference electrode 52 are positioned symmetrically with respect to the center line CL when viewed along the first direction Z (see Figure 4), but are not limited to this.

[0030] As shown in Figure 7, blood pressure values ​​and electrocardiogram waveforms are measured by, for example, placing the blood pressure monitor body 10 on a table 300, attaching the cuff 20 to the upper arm of the person being measured (in Figure 7, as an example, the upper arm of the left arm of the person being measured), and assuming a measurement posture in which both of the person being measured's elbows rest on the table 300. The measurement posture is such that the person being measured wraps both hands around the blood pressure monitor body 10 so that the wrist of the person's left hand 110 is in contact with the first measuring electrode 41 and the first reference electrode 51, and the wrist of the person being measured's right hand 120 is in contact with the second measuring electrode 42 and the second reference electrode 52. In the measurement posture, the person being measured holds the housing 30 by applying force in the third direction X, bringing both hands closer together, with the left hand 110 in contact with the first side surface 34 and the right hand 120 in contact with the second side surface 35. In other words, the direction of the force required by the person being measured to maintain the measurement posture is only one axis (in this embodiment, only the third direction X). Therefore, even elderly people can stably make contact with the measuring electrodes and reference electrodes of the blood pressure monitor body 10 when it is placed on a flat surface, making it easier to maintain an accurate measurement posture.

[0031] As an example, as shown in Figure 5, the top surface 36 is inclined such that it moves away from the bottom surface 31 in the first direction Z as it moves from the front surface 32 to the rear surface 33 in the second direction Y. The angle θ2 of the top surface 36 with respect to the bottom surface 31 is, for example, about 15 degrees. As shown in Figures 2 to 4, the top surface 36 is provided with a display unit 14, a communication switch 17, and a start / stop switch 18. The display unit 14, the communication switch 17, and the start / stop switch 18 are located near the center line CL, away from the first side surface 34 and the second side surface 35 (see Figure 4).

[0032] The blood pressure monitor unit 10 can provide the following effects.

[0033] The blood pressure monitor body 10 comprises a housing 30 and a first measuring electrode 41 and a second measuring electrode 42 provided on the housing 30, respectively. The housing 30 includes a bottom surface 31 and a front surface 32, a rear surface 33, a first side surface 34, and a second side surface 35, each extending in a first direction Z. The front surface 32 and the rear surface 33 are spaced apart in a second direction Y. The first side surface 34 and the second side surface 35 are spaced apart in a third direction X and are symmetrically positioned with respect to a center line CL that passes through the center of the housing 30 in the third direction X and extends along the second direction Y when viewed along the first direction Z. Each of the first side surface 34 and the second side surface 35 is curved to protrude in the second direction Y and away from the center line CL. The first measuring electrode 41 is provided on the first side surface 34, and the second measuring electrode 42 is provided on the second side surface 35. Each of the first measuring electrode 41 and the second measuring electrode 42 is positioned closer to the front surface 32 than to the rear surface 33 when viewed along the first direction Z, and the first measuring electrode 41 is configured to be able to contact the wrist of the left hand of the person being measured when the front surface 32 is facing the person being measured, and the second measuring electrode 42 is configured to be able to contact the wrist of the right hand of the person being measured. With this configuration, a stable electrocardiogram signal can be obtained at the wrist of the person being measured, so that a blood pressure monitor body 10 can be realized that can measure blood pressure values ​​and electrocardiogram waveforms more accurately.

[0034] The blood pressure monitor unit 10 allows for simultaneous measurement of electrocardiogram and blood pressure, with the force direction being unified and maintaining a stable posture. This enables electrocardiogram measurement without being affected by hand tremors, and allows for maintaining a measurement posture that enables accurate blood pressure measurement.

[0035] The blood pressure monitor body 10 includes a first reference electrode 51 provided on a first side surface 34 and a second reference electrode 52 provided on a second side surface 35. The first reference electrode 51 is positioned adjacent to the first measuring electrode 41 with a gap in the first direction Z, and the second reference electrode 52 is positioned adjacent to the second measuring electrode 42 with a gap in the first direction Z. When the front surface 32 is facing the person being measured, the first reference electrode 51 is configured to be able to contact the wrist of the person's left hand together with the first measuring electrode 41, and the second reference electrode 52 is configured to be able to contact the wrist of the person's right hand together with the second measuring electrode 42. This configuration makes it possible to remove noise that may be included in the electrocardiogram waveform. As a result, a blood pressure monitor body 10 that can measure blood pressure values ​​and electrocardiogram waveforms more accurately can be realized.

[0036] The first measuring electrode 41 is positioned further from the bottom surface 31 than the first reference electrode 51 in the first direction Z, and the second measuring electrode 42 is positioned further from the bottom surface 31 than the second reference electrode 52 in the first direction Z. With this configuration, the first measuring electrode 41 and the second measuring electrode 42 are more likely to come into contact with the subject's hand compared to the case where each measuring electrode is positioned closer to the bottom surface than each reference electrode. As a result, a blood pressure monitor body 10 that can measure blood pressure values ​​and electrocardiogram waveforms more accurately can be realized.

[0037] The first measuring electrode 41 is larger than the first reference electrode 51, and the second measuring electrode 42 is larger than the second reference electrode 52. This configuration makes it easier for the first measuring electrode 41 and the second measuring electrode 42 to come into contact with the subject's hand compared to the case where each measuring electrode is smaller than each reference electrode. As a result, a blood pressure monitor body 10 that can measure blood pressure values ​​and electrocardiogram waveforms more accurately can be realized.

[0038] The first measuring electrode 41 protrudes from the first side surface 34, and the second measuring electrode 42 protrudes from the second side surface 35. This configuration makes it easier for the first measuring electrode 41 and the second measuring electrode 42 to come into contact with the subject's hand compared to a case where the measuring electrodes do not protrude from their respective sides. As a result, a blood pressure monitor body 10 that can measure blood pressure values ​​and electrocardiogram waveforms more accurately can be realized.

[0039] When viewed along the second direction Y, the first side surface 34 and the second side surface 35 are inclined so as to approach each other in the third direction X as they move away from the bottom surface 31 in the first direction Z. With such a configuration, the person being measured can stably hold the sphygmomanometer main body 10, so that even an elderly person can easily maintain the measurement posture.

[0040] When viewed along the third direction X, the front surface 32 and the rear surface 33 are inclined so as to approach each other in the second direction Y as they move away from the bottom surface 31 in the first direction Z. With such a configuration, the person being measured can stably hold the sphygmomanometer main body 10, so that even an elderly person can easily maintain the measurement posture.

[0041] The rear surface 33 includes a connection portion 71 to which a tube 70 connected to the cuff 20 for pressing the measurement site of the person being measured is connected. For example, assume that the sphygmomanometer main body 10 is configured to measure blood pressure values and electrocardiogram waveforms using an application installed in the smartphone 200. In this case, by configuring as described above, a smartphone can be placed between the person being measured and the sphygmomanometer main body 10 (see FIG. 7), so that the convenience of the person being measured can be improved.

[0042] The first measurement electrode 41 and the second measurement electrode 42 are symmetrically positioned with respect to the center line CL when viewed along the first direction Z. With such a configuration, a sphygmomanometer main body 10 capable of more accurately measuring blood pressure values and electrocardiogram waveforms can be realized.

[0043] The top surface 36 is inclined so as to move away from the bottom surface 31 in the first direction Z as it goes from the front surface 32 to the rear surface 33 in the second direction Y. With such a configuration, the visibility of the top surface 36 in the state where the measurement posture is maintained is enhanced, and for example, the information displayed on the display unit 14 can be easily confirmed.

[0044] The sphygmomanometer main body 10 can be configured as follows.

[0045] The first reference electrode 51 and the second reference electrode 52 can be omitted.

[0046] The first side surface 34 and the second side surface 35 are not limited to being inclined so as to approach each other in the third direction X as they move away from the bottom surface 31 in the first direction Z when viewed along the second direction Y. For example, the first side surface 34 and the second side surface 35 may be configured to be orthogonal to the bottom surface 31.

[0047] The front surface 32 and the rear surface 33 are not limited to being inclined so as to approach each other in the second direction Y as they move away from the bottom surface 31 in the first direction Z when viewed along the third direction X. For example, as shown in FIG. 8, the front surface 32 and the rear surface 33 may be configured to be substantially parallel to each other and inclined with respect to the bottom surface 31, or may be configured to be orthogonal to the bottom surface 31. The sphygmomanometer main body 10 in FIG. 8 includes a display unit 14, a communication switch 17, and a start / stop switch 18 provided on the front surface 32, and does not include a first reference electrode 51 and a second reference electrode 52.

[0048] The rear surface 33 may include a protrusion that can catch the finger of the person to be measured. By configuring it in this way, it is possible to prevent the person to be measured from placing their hand at the wrong position of the housing 30.

[0049] As described above, various embodiments in the present disclosure have been described in detail with reference to the drawings. Finally, various aspects of the present disclosure will be described. In the following description, for example, reference numerals will be added for description.
