Description

Technical Field

[0001] The invention relates to a blood pressure measuring device. Background Art

[0002] In recent years, blood pressure measuring devices for measuring blood pressure have been used as a way to check health status not only in medical facilities but also at home. The blood pressure measuring device measures blood pressure by, for example, inflating and deflating a cuff wrapped around a wrist of a living body, detecting the pressure of the cuff with a pressure sensor, and thereby detecting the vibration of the arterial wall.

[0003] In addition, as disclosed in Japanese Patent Publication No. 2022-116594, as a blood pressure measuring device, a wearable blood pressure monitor worn on a wrist is known. Such a blood pressure measuring device uses a flow path plate unit in order to reduce the size. The flow path plate unit is connected to parts such as a pressure sensor, an opening and closing valve, and a flow path obstruction member.

[0006] Patent Document 1: Japanese Patent Application Publication No. 2022-116594 Summary of the invention

[0007] Problems to be solved by the invention

[0008] In the above-mentioned blood pressure measuring device, in order to inspect each component after connecting each component, it is necessary to block unnecessary flow paths. However, if a mechanism for blocking unnecessary flow paths is provided in the flow path plate unit, the flow path plate unit will become larger, and there is a problem that inspection cannot be performed without changing the size of the flow path plate unit.

[0009] Therefore, an object of the present invention is to provide a blood pressure measurement device that can individually inspect components provided in a flow channel plate unit without increasing the size of the flow channel plate unit.

[0010] Solutions for solving problems

[0011] According to one embodiment, a blood pressure measuring device is provided, comprising: a housing; a plurality of parts, including a pump disposed in the housing, a valve disposed in the housing, and a pressure sensor disposed in the housing; and a flow path plate unit, forming a plurality of internal flow paths, wherein one end of the plurality of internal flow paths is respectively connected to the plurality of parts, and the other end is selectively connected to at least one of a plurality of cuffs and a plurality of inspection machines, wherein the plurality of inspection machines respectively inspect the plurality of parts.

[0012] According to this solution, the multiple internal flow paths of the flow path plate unit can respectively connect any part to one of the cuff and the inspection machine. As a result, the internal flow paths of the flow path plate unit connected to each part are independent. Therefore, when the blood pressure measuring device is in a usable state, the flow path plate unit can connect the parts and the cuff. In addition, when the blood pressure measuring device is in an inspection state during manufacturing and maintenance, the parts and the inspection machine can be connected, and can be sealed when no inspection is performed. Therefore, the blood pressure measuring device can inspect the parts provided in the flow path plate unit one by one without increasing the size of the flow path plate unit.

[0013] In the blood pressure measuring device of one of the above-mentioned schemes, the multiple cuffs include a pressing cuff and a sensing cuff, the flow path plate unit has a first flow path baffle and a second flow path baffle, and the multiple internal flow paths include an internal flow path connecting the pressing cuff and the first flow path baffle, an internal flow path connecting the first flow path baffle and the sensing cuff, an internal flow path connecting the sensing cuff and the second flow path baffle, and an internal flow path connecting the second flow path baffle and the atmosphere.

[0014] According to this scheme, the blood pressure measuring device includes an internal flow path that can respectively connect the compression cuff and the first flow path obstruction member, the first flow path obstruction member and the sensing cuff, the sensing cuff and the second flow path obstruction member, and the second flow path obstruction member and the atmosphere. Therefore, by connecting the inspection machine to the internal flow path connected to the first flow path obstruction member and the second flow path obstruction member, the first flow path obstruction member and the second flow path obstruction member can also be inspected.

[0015] In the blood pressure measuring device of the above-mentioned scheme, the internal flow path connecting the compression cuff and the first flow path baffle is also connected to the pump, and the internal flow path connecting the first flow path baffle and the sensing cuff and the internal flow path connecting the sensing cuff and the second flow path baffle are continuous and formed as one.

[0016] According to this solution, the blood pressure measuring device is connected to the pump, the pressing cuff and the first flow path obstruction member, and the internal flow path connection inspection machine is used to replace the pressing cuff, and the internal flow path connection inspection machine is used to replace the sensing cuff when the first flow path obstruction member, the second flow path obstruction member and the sensing cuff are connected. Therefore, the blood pressure measuring device can inspect the first flow path obstruction member and the second flow path obstruction member.

[0017] In the blood pressure measurement device according to the above aspect, the flow path plate unit has a plurality of ports, the plurality of cuffs and the plurality of inspection machines can be connected to the plurality of ports, respectively, and the plurality of ports are connected to the plurality of internal flow paths, respectively.

[0018] According to this solution, the blood pressure measuring device can selectively connect each cuff and the inspection machine to the flow path plate unit via a plurality of ports. Therefore, the blood pressure measuring device can facilitate the attachment and detachment of the cuff and the inspection machine and the sealing of the ports, and can easily inspect various parts.

[0019] Effects of the Invention

[0020] According to the present invention, it is possible to provide a blood pressure measurement device capable of inspecting components provided in a flow channel plate unit one by one without increasing the size of the flow channel plate unit. BRIEF DESCRIPTION OF THE DRAWINGS

Fig.12 This is a block diagram showing an example of inspection of parts provided in the flow channel plate unit 24 of the blood pressure measurement device 1 .

[0043] like Figures 1 to 3 As shown, the blood pressure measuring device 1 includes, for example, a device body 3, a first cuff structure 4, a second cuff structure 5, and a band 6. The blood pressure measuring device 1 is formed such that the first cuff structure 4 and the second cuff structure 5 extend from the device body 3 in opposite directions to the device body 3, and the band 6 covers the first cuff structure 4 and the second cuff structure 5, and can be fixed to a wrist 300 as a living body through the band 6.

[0044] like Figures 1 to 5 , Figure 8 and Fig. 9 As shown, the device body 3 includes, for example, a housing 11, a display unit 12, an operating unit 13, a pump 14, an acceleration sensor 15, a valve 16, a pressure sensor 17, a battery 18, a communication unit 19, a biosensor 20, a charging circuit unit 21, a memory 22, a processor 23, a fluid circuit 24, and a substrate 25.

[0045] The housing 11 is a housing that accommodates the components of the device body 3. The housing 11 accommodates, for example, a display unit 12, an operation unit 13, a pump 14, an acceleration sensor 15, a valve 16, a pressure sensor 17, a battery 18, a communication unit 19, a biosensor 20, a charging circuit unit 21, a memory 22, a processor 23, a fluid circuit 24, and a substrate 25.

[0046] like Figures 5 to 7 As shown, the housing 11 includes, for example, a shell shell 31 , a windshield 32 covering an upper opening of the shell shell 31 , and a cuff cover 33 provided below the shell shell 31 .

[0047] The outer shell 31 is formed into a bottomed cylindrical shape, for example, a cylindrical shape, a rectangular cylindrical shape, or a polygonal cylindrical shape having a bottom. In the present embodiment, an example in which the outer shell 31 is formed into a bottomed rectangular cylindrical shape is shown. As a specific example, the outer shell 31 has: a rectangular cylindrical peripheral wall portion 31a; a bottom portion 31b provided on the peripheral wall portion 31a; and a pair of ring portions 31c provided on a pair of opposite sides of the outer peripheral surface of the peripheral wall portion 31a.

[0048] The peripheral wall portion 31a is provided with, for example, an opening 31d in which a part of the operation portion 13 is disposed. For example, the opening 31d is formed on a surface of the peripheral wall portion 31a different from the two surfaces on which the pair of ring portions 31c are provided. In addition, for example, two openings 31d are formed on one surface of the peripheral wall portion 31a.

[0049] The bottom 31b constitutes the back side (bottom 31b) of the housing 11 (outline housing 31). The bottom 31b protrudes in a manner that a portion can contact the wrist 300, for example. For example, the bottom 31b has a protrusion 31b1 formed by the central side of the outer surface side protruding in a rectangular shape, and the central side of the inner surface side of the bottom 31b is recessed in a rectangular shape. In addition, the bottom 31b is formed with: a plurality of window portions 31b2, in which the biosensor 20 is arranged; and a plurality of hole portions 31b3, in which the connection portion 73 and the connection portion 83 described later are arranged as components for connecting the first cuff structure 4 and the second cuff structure 5 to the pump 14 fluid.

[0050] The biosensor 20 is arranged on the inner surface side of the protrusion 31b1. The protrusion 31b1 constitutes a sensor unit, which includes at least one of the biosensor 20 and the charging terminal 214 arranged on the back side of the housing 11. Here, the biosensor 20 and the charging terminal 214 arranged on the back side of the housing 11 mean that a part of the parts constituting the biosensor 20 is exposed on the back side of the housing 11 or is arranged on the back side of the housing 11 via a member other than the first cuff structure 4 and the second cuff structure 5 (for example, the cover 31b5 described later).

[0051] The window portion 31b2 is formed in the protruding portion 31b1. Figure 5 As shown, the window portion 31b2 is formed of a plurality of openings 31b4 formed at a plurality of locations of the protruding portion 31b1 and a light-transmitting cover 31b5 made of glass, resin or the like covering the openings 31b4. The cover 31b5 covers the outer surface of the protruding portion 31b1, for example.

[0052] A plurality of holes 31b3 are formed between the protrusion 31b1 and each ring 31c in the bottom 31b. In the present embodiment, a plurality of holes 31b3 are formed between the protrusion 31b1 and one ring 31c, and a plurality of holes 31b3 are formed between the protrusion 31b1 and another ring 31c. The plurality of holes 31b3 disposed adjacent to each ring 31c are arranged in one direction, for example, in a direction orthogonal to the opposing direction of a pair of rings 31c. That is, in the bottom 31b as the back side of the housing 11, at one end in one direction, a plurality of holes 31b3 for fixing a part of the first cuff structure 4 are arranged at a position separated from the protrusion 31b1, and at the other end in the one direction, a plurality of holes 31b3 for fixing another part of the first cuff structure 4 and the second cuff structure 5 are arranged to be separated from the protrusion 31b1 in the other direction. It should be noted that the number and arrangement of the hole portions 31 b 3 are appropriately set according to the number and arrangement of a plurality of ports 24 c , which will be described later, formed in the flow path plate 24 a .

[0053] In addition, a slit-shaped vent 31b6 that is long in one direction is formed in the bottom 31b, and the bottom 31b is provided with a waterproof and breathable sheet 31b7 that covers the vent 31b6. The waterproof and breathable sheet 31b7 is formed to prevent water from entering the housing 11 from the outside through the vent 31b6 of the bottom 31b, and to allow ventilation between the inside and the outside of the housing 11. Here, the vent 31b6 and the waterproof and breathable sheet 31b7 are provided at a position that does not overlap with the first cuff structure 4 and the second cuff structure 5 fixed to the bottom 31b, that is, at a position separated from the first cuff structure 4 and the second cuff structure 5. For example, in a direction orthogonal to the opposing direction of the pair of ring portions 31c, a flow path body 72 of a first pressing cuff 52 described later of the first cuff structure 4 is provided adjacent to one side of the protruding portion 31b1, and the vent 31b6 and the waterproof and breathable sheet 31b7 are provided adjacent to the other side of the protruding portion 31b1.

[0054] The ring portion 31c is formed so that the strap 6 can pass therethrough and the strap 6 can be fixed or folded back. For example, the ring portion 31c is a rectangular ring-shaped member having an opening that is long in one direction and through which the strap 6 can be inserted. The ring portion 31c is integrally formed on the outer side surface of the profile housing 31. One end of the strap 6 is fixed to the ring portion 31c of one of the pair of ring portions 31c, and the strap 6 is folded back to the other ring portion 31c.

[0055] The windshield 32 is a glass plate having the same shape as the outer peripheral edge shape of the outer shell 31, and in this embodiment, is a rectangular shape. It should be noted that the windshield 32 is not limited to a glass plate as long as it is a transparent or light-transmitting material.

[0056] The cuff cover 33 covers the bottom 31b of the outer shell 31. The cuff cover 33 is provided with a protruding portion 31b1 of the bottom 31b, and an opening 33a is formed to expose the protruding portion 31b1 to the outside. For example, the cuff cover 33 is formed with a thickness and shape such that the protruding portion 31b1 protrudes from the main surface of the cuff cover 33 facing the wrist 300 when the cuff cover 33 is fixed to the bottom 31b. In addition, for example, the cuff cover 33 is formed with holes 33b for screw placement at four corners, and is detachably fixed to the bottom 31b of the outer shell 31 of the housing 11 by screws or the like.

[0057] The cuff cover 33 covers the ends of the first cuff structure 4 and the second cuff structure 5 arranged at the bottom 31b, arranges the ends of the first cuff structure 4 and the second cuff structure 5 in the gap generated between the bottom 31b, and fixes the first cuff structure 4 and the second cuff structure 5 to the bottom 31b. As a specific example, the cuff cover 33 covers a part of the flow path body 72 and the connection part 73 of the first pressing cuff 52, the flow path body 82 and the plurality of connection parts 83 of the sensing cuff 54, and the flow path body 92 and the plurality of connection parts 93 of the second pressing cuff 62 described later. In addition, the cuff cover 33 restricts the movement of the covered parts of the part of the first pressing cuff 52, the sensing cuff 54, and the second pressing cuff 62 away from the bottom 31b, thereby fixing the first cuff structure 4 and the second cuff structure 5. It should be noted that the cuff cover 33 can also be configured with a buffer between the first cuff structure 4 and the second cuff structure 5.

[0058] The display unit 12 is arranged directly below the windshield 32. The display unit 12 is electrically connected to the processor 23. The display unit 12 is, for example, a liquid crystal display or an organic electroluminescent display. As a specific example, the display unit 12 is an OLED (Organic Light Emitting Diode). The display unit 12 displays various information including date and time, blood pressure values ​​such as the highest blood pressure and the lowest blood pressure, measurement results such as heart rate, and information such as the charging status and remaining amount of the battery 18. The display unit 12 is formed in the same shape as the windshield 32 or a shape slightly smaller than the windshield 32 when viewed from above.

[0059] The operation unit 13 is configured to be able to input commands from the user. The operation unit 13 includes, for example, a plurality of buttons 41 provided on the housing 11; a sensor that detects the operation of the buttons 41; and a touch panel 43 provided on the display unit 12 or the windshield 32. The operation unit 13 converts the command into an electrical signal by the user's operation. The sensor and the touch panel 43 are electrically connected to the processor 23, and output the electrical signal corresponding to the operation to the processor 23.

[0060] The pump 14 is, for example, a piezoelectric pump. The pump 14 compresses air as a fluid, for example, and supplies the compressed air to the air bag 71 of the first compression cuff 52 described later and the air bag 81 of the sensing cuff 54 of the first cuff structure 4, and the air bag 91 of the second compression cuff 62 described later of the second cuff structure 5, via the fluid circuit 24. The pump 14 is electrically connected to the processor 23. The pump 14 has a valve mechanism inside that opens and closes the flow path connected to the flow path plate 24a.

[0061] The acceleration sensor 15 is, for example, a triaxial acceleration sensor. The acceleration sensor 15 measures acceleration, for example, and outputs an analog signal. The acceleration sensor 15 is connected to the processor 23 via, for example, an A / D conversion circuit.

[0062] The valve 16 is, for example, an on-off valve. The valve 16 opens and closes the fluid circuit connecting the pump 14 and the first cuff structure 4 and / or the second cuff structure 5 in the fluid circuit 24 and / or the fluid circuit connecting the first cuff structure 4 and the outside (atmosphere). In the present embodiment, the valve 16 opens and closes the fluid circuit (the second internal flow path 242 described later) connected to the second pressing cuff 62 described later of the second cuff structure 5. The valve 16 is electrically connected to the processor 23. For example, the valve 16 is opened and closed by the control of the processor 23.

[0063] As a specific example, the valve 16 is a valve that releases the air supplied to the first cuff structure 4 and the second cuff structure 5 to the atmosphere. For example, when blood pressure is measured, when air is supplied to the first pressing cuff 52, the second pressing cuff 62, and the sensing cuff 54, the valve 16 is switched to a closed state by the control of the processor 23. In addition, when the first pressing cuff 52, the second pressing cuff 62, and the sensing cuff 54 are exhausted, the valve 16 is switched from a closed state to an open state by the control of the processor 23. In addition, the valve 16 can also be formed to be able to adjust the opening degree.

[0064] The pressure sensor 17 is provided in the fluid circuit 24, for example. The pressure sensor 17 detects the pressure of the first compression cuff 52 and / or the sensing cuff 54. For example, the pressure sensor 17 detects the pressure of the sensing cuff 54. The pressure sensor 17 is electrically connected to the processor 23, for example, via an A / D conversion circuit, converts the detected pressure into an electrical signal, and outputs it to the processor 23.

[0065] The battery 18 is, for example, a secondary battery such as a lithium-ion battery that can be charged and discharged. The battery 18 is electrically connected to the processor 23. The battery 18 supplies power to the processor 23. The battery 18 supplies driving power to each component of the processor 23, and supplies driving power to the display unit 12, the operation unit 13, the pump 14, the acceleration sensor 15, the valve 16, the pressure sensor 17, the communication unit 19, and the biosensor 20 via the processor 23.

[0066] The communication unit 19 is configured to be able to send and receive information with an external device wirelessly and / or wired. The communication unit 19 is, for example, a wireless communication module in accordance with a wireless communication standard. The communication unit 19, for example, sends information obtained by the processor 23, measured blood pressure values ​​and pulse information to an external device, and also receives a program for software update from an external device and sends it to the control unit. In this embodiment, the external device is, for example, an external terminal such as a smart phone, a tablet terminal, a personal computer, a smart watch, etc.

[0067] In this embodiment, the communication unit 19 and the external terminal can be connected directly or via a network. The communication unit 19 and the external terminal can also be connected via a mobile communication network such as 4G (fourth generation mobile communication technology) and 5G (fifth generation mobile communication technology), Wimax (World Interoperability for Microwave Access), Wi-Fi (registered trademark) and other wireless communication lines. In addition, the communication unit 19 and the external terminal can also be connected through wireless communication units such as BLE (Bluetooth (registered trademark) Low Energy), NFC (Near Field Communication), and infrared communication. In addition, the communication unit 19 can also have a universal connector such as a micro USB (Universal Serial Bus) and a dedicated connector for the blood pressure measurement device 1 in addition to a wireless communication module, and can be directly connected to the external terminal through various cables such as a USB cable or connected to the external terminal via a wired communication line such as a LAN (Local Area Network) connection. Therefore, the communication unit 19 can also be composed of multiple communication units such as a wireless antenna and a micro USB connector. It should be noted that the connector for wired communication may be a dedicated connector for the blood pressure measurement device 1 .

[0068] The biosensor 20 is a sensor that can detect information of a living body by contacting or facing the wrist 300. The biosensor 20 converts the detected information of the living body into an electrical signal and outputs it to the processor 23. The biosensor 20 may be, for example, a sensor that measures physical quantities such as heart rate and body temperature, or a sensor that measures chemical quantities such as blood sugar level and blood oxygen concentration. In this embodiment, the biosensor 20 includes, for example, a PPG sensor 20a, an SpO2 sensor 20b, and an ECG sensor 20c.

[0069] For example, the PPG sensor 20a measures the heart rate by photoplethysmography. For example, the PPG sensor 20a includes a first LED 20d, a second LED 20e, and a first PD (Photodiode) 20f.

[0070] For example, the SpO2 sensor 20b measures saturation (transcutaneous arterial oxygen saturation). The SpO2 sensor 20b includes a second LED 20e and a second PD 20g. Here, for example, the PPG sensor 20a and the SpO2 sensor 20b share the second LED 20e.

[0071] For example, the ECG sensor 20c measures the current in the heart and acquires an electrocardiogram waveform. For example, the ECG sensor 20c includes a pair of electrocardiogram electrodes 20c1.

[0072] The charging circuit unit 21 includes, for example, an antenna unit 211, a power receiving unit 212, a charging unit 213, and a charging terminal 214. The charging circuit unit 21 charges the battery 18 by wired power supply and / or wireless power supply. For example, the charging circuit unit 21 receives the transmission power transmitted from the antenna unit 103 of the power transmission device 100 provided outside by the antenna unit 211 to charge the battery 18. In addition, for example, the charging circuit unit 21 receives the transmission power transmitted from the power transmission terminal 104 of the power transmission device 100 provided outside by the charging terminal 214 to charge the battery 18. That is, the charging circuit unit 21 receives power from the power transmission device 100 by selectively using the antenna unit 211 and the charging terminal 214, thereby charging the battery 18. It should be noted that the charging circuit unit 21 can be formed to be capable of both wired power supply and wireless power supply, and can also be formed to be capable of only one of wired power supply and wireless power supply.

[0073] The antenna unit 211 receives the transmission power from the antenna unit 103 of the power transmission device 100. The antenna unit 211 is, for example, a power receiving coil as a power receiving resonance circuit. The antenna unit 211 supplies the received power to the power receiving unit 212. The power receiving surface of the antenna unit 211 is formed in a planar shape. The antenna unit 211 is, for example, arranged in the housing 11. As a specific example, the antenna unit 211 is arranged in the housing 11 and adjacent to the display unit 12 on the side of the display unit 12 opposite to the windshield 32. The antenna unit 211 includes, for example, a resonant capacitor, and constitutes a power receiving resonance circuit.

[0074] The power receiving unit 212 rectifies the power received through the antenna unit 211 or the charging terminal 214, and supplies it to the charging unit 213. As a specific example, the power receiving unit 212 rectifies the power received from the antenna unit 211 to convert it from AC to DC. For example, the power receiving unit 212 includes a rectifier circuit and a control circuit, and the control circuit controls the operation of the rectifier circuit to output the rectified DC power to the charging unit 213.

[0075] The charging unit 213 supplies the power supplied from the power receiving unit 212 as charging power to the battery 18. For example, the charging unit 213 converts the power supplied from the power receiving unit 212 into a predetermined current value and voltage value and supplies the converted power to the battery 18. In addition, for example, the charging unit 213 may include a circuit that outputs the charging state of the battery 18 to the power receiving unit 212 and / or the processor 23.

In addition, the processor 23 displays the various actions performed and the conditions and results of calculations, analysis, processing, etc. on the display unit 12 through a program or application.

[0079] The fluid circuit 24 fluidically connects at least two of the pump 14, the valve 16, the pressure sensor 17, the first cuff structure 4, and the second cuff structure 5, which are provided in the housing 11. The fluid circuit 24 may include, for example, a pipe or a flow path plate 24a that forms a flow path of the fluid supplied from the pump 14 to the first cuff structure 4, a single or multiple throttles 24b that are flow path obstructions that control the supply amount and pressure of the fluid supplied to the first cuff structure 4 and / or the second cuff structure 5, and a check valve that controls the flow direction of the fluid. In the present embodiment, the fluid circuit 24 is a flow path plate unit having a flow path plate 24a and multiple throttles 24b.

[0080] The flow path plate 24a is formed by joining a plurality of plates formed of a resin material or a metal material to a sheet or a double-sided tape disposed between adjacent plates and having a slit formed therein as a flow path. A plurality of throttle members 24b are provided in the flow path plate 24a. In the present embodiment, the throttle member 24b connected between the first pressing cuff 52 and the sensing cuff 54 described later of the first cuff structure 4 is set as the first flow path blocker 24b1, and the throttle member 24b connected to the secondary side of the sensing cuff 54 is set as the second flow path blocker 24b2 for explanation.

[0081] The substrate 25 includes, for example, a control substrate 25a, a sensor main substrate 25b, and a sensor sub-substrate 25c.

[0082] For example, the acceleration sensor 15 , the valve 16 , the pressure sensor 17 , the communication unit 19 , the circuit configuration of the charging circuit unit 21 , the memory 22 , and the processor 23 are mounted on the control substrate 25 a .

[0084] Various circuits and electronic components constituting the PPG sensor 20a, the SpO2 sensor 20b, and the ECG sensor 20c are mounted on the sensor sub-substrate 25c. For example, the control substrate 25a, the sensor main substrate 25b, and the sensor sub-substrate 25c are electrically connected.

[0085] Below, use Figures 1 to 3 , Figure 5 A specific example of the first cuff structure 4 will be described. Figures 1 to 3 , Figure 5 As shown, the first cuff structure 4 includes a first collar 51, a first pressing cuff 52, a back plate 53 and a sensing cuff 54. The first cuff structure 4 includes, for example, the first collar 51, the first pressing cuff 52, the back plate 53 and the sensing cuff 54. The first cuff structure 4 is formed by sequentially stacking the first collar 51, the first pressing cuff 52, the back plate 53 and the sensing cuff 54 toward the wrist 300. It should be noted that the first cuff structure 4 may also be a structure without the first collar 51 and / or the back plate 53.

[0086] For example, one end side of the first collar 51 is fixed to the bottom 31b provided on the wrist 300 side of the housing 11. The first collar 51 is formed into a band shape that is bent into a shape that follows the circumferential direction of the wrist 300. The first collar 51 is made of a resin material. The first collar 51 is formed of a material with low hardness that has flexibility and shape retention. Here, flexibility means that the shape is deformed in the radial direction when an external force from the strap 6 is applied to the first collar 51. Shape retention means that the first collar 51 can maintain a shape given in advance when no external force is applied. That is, the first collar 51 is formed of a resin material that has a hardness that allows elastic deformation such as bending deformation that changes the shape, especially the curvature of the bent portion, without compression deformation or almost compression deformation. Therefore, the first collar 51 is formed so as to be elastically deformable in the following manner: by bending deformation due to the application of external force, the internal space for the wrist 300 to be arranged is enlarged or reduced in accordance with the shape of the wrist to be worn. For example, the first collar 51 is formed of thermoplastic polyurethane resin (hereinafter referred to as TPU) or polypropylene resin.

[0087] In addition, one end side of the first collar 51 is fixed to the housing 11. In addition, the first collar 51 is formed to have a length that faces at least one of the two arteries 311 and 312 when the blood pressure measurement device 1 is worn on the wrist 300 with the longest circumference among the assumed wearer. Preferably, the first collar 51 is formed to have a length that faces the two arteries 311 and 312 when the blood pressure measurement device 1 is worn on the wrist 300 with the longest circumference among the assumed wearer. In addition, the first collar 51 is set to have a length that does not contact the device body 3 at the other end when the blood pressure measurement device 1 is worn on the wrist 300 with the shortest circumference among the assumed wearer. The first collar 51 is bent, for example, at a predetermined radius of curvature so that the portion of the device body 3 extending from the housing 11 follows the shape of the side of the wrist 300 on one of the left and right sides of the wrist 300 and the palm side of the wrist 300.

[0088] The first pressing cuff 52 is fixed to the inner peripheral surface of the first collar 51 by double-sided tape, adhesive, heat fusion, etc. The first pressing cuff 52 is fluidically connected to the pump 14 via the fluid circuit 24. One main surface of the first pressing cuff 52 is fixed to the inner surface of the first collar 51. The first pressing cuff 52 presses the back of the wrist 300 by inflating, and presses the back plate 53 and the sensing cuff 54 toward the wrist 300 side.

[0089] The first compression cuff 52 includes, for example, a single or multiple air bags 71, a flow path body 72 provided at the end of the air bag 71, and a connection portion 73 such as a pipe joint provided at the flow path body 72 and connected to the fluid circuit 24. Here, the air bag 71 refers to a bag-shaped structure. In this embodiment, the blood pressure measurement device 1 is configured to use air through the pump 14, so an air bag is used for description. However, when a fluid other than air is used, the bag-shaped structure can be any fluid bag that is expanded by the fluid. The air bag 71 is formed in a rectangular bag shape that is long in one direction.

[0090] In the air bag 71, a plurality of sheet members are formed into a bag shape by heat welding or the like. For example, when the first pressing cuff 52 is configured to have a plurality of air bags 71, the plurality of air bags 71 are stacked and integrated by welding or the like, and are fluidically continuous. The sheet member forming the air bag 71 is formed, for example, of a thermoplastic elastomer. Here, the thermoplastic elastomer is, for example, TPU.

[0091] The flow path body 72 is provided integrally with a portion of the edge of one side in the long dimension direction of the air bag 71, for example. The flow path body 72 is formed by a portion of two sheet members among the plurality of sheet members forming the air bag 71. In addition, the flow path body 72 is formed in a shape that is long in one direction with a width smaller than the width in the short dimension direction of the air bag 71. The flow path body 72 is provided integrally with a connection portion 73 at the top end. The flow path body 72 is connected to the fluid circuit 24 via the connection portion 73, and constitutes a flow path between the fluid circuit 24 and the air bag 71. The thickness of the flow path body 72 when inflated is smaller than the thickness of the air bag 71 when inflated.

[0092] For example, one connection portion 73 is provided. One connection portion 73 is connected to the fluid circuit 24 via one hole portion 31 b 3 formed in the bottom portion 31 b .

[0093] It should be noted that, for example, the flow path body 72 extends from one end side of the bottom 31b to the other end side in the opposing directions of the pair of ring portions 31c in order to avoid the protrusion 31b1 formed on the bottom 31b, adjacent to the protrusion 31b1, and the connecting portion 73 is connected to one of the multiple hole portions 31b3 formed at the end of the bottom 31b on the side where the second cuff structure 5 protrudes.

[0094] The back plate 53 is fixed to the surface of the first compression cuff 52 on the wrist 300 side by double-sided tape, adhesive, etc. The back plate 53 is formed of a resin material. The back plate 53 is formed, for example, in the shape of a rectangular plate that is long in one direction. It should be noted that the back plate 53 may be, for example, a divided structure, that is, a plurality of rectangular small pieces are arranged in one direction. The back plate 53 has shape-following properties.

[0095] Here, shape conformability refers to the function of the back plate 53 being able to deform in a manner that imitates the shape of the contacted part of the wrist 300 to be configured. The contacted part of the wrist 300 refers to the area of ​​the wrist 300 that contacts the back plate 53. The contact here includes both direct contact with the back plate 53 and indirect contact with the back plate 53 via the sensing cuff 54.

[0096] The sensing cuff 54 is fixed to the main surface of the wrist side of the back plate 53. The sensing cuff 54 is in direct contact with the area of ​​the wrist 300 where the artery 311 and the artery 312 exist, or is in indirect contact through a cover or the like. The sensing cuff 54 is formed into a rectangular shape that is long in one direction. It should be noted that the sensing cuff 54 can also be a structure that contacts the area of ​​the wrist 300 where one artery 311 and the artery 312 exist. The sensing cuff 54 is the same as or smaller than the first pressing cuff 52 in the long dimension direction. In addition, the sensing cuff 54 is the same as or smaller than the first pressing cuff 52 in the short dimension direction. The sensing cuff 54 is the same shape as the back plate 53 in the long dimension direction and the width direction of the back plate 53, or is smaller or larger than the back plate 53. The sensing cuff 54 compresses the area where the artery exists on the palm side of the wrist by inflating. The sensing cuff 54 is pressed toward the living body via the back plate 53 by the inflated first pressing cuff 52 .

[0097] As a specific example, the sensing cuff 54 includes an air bag 81, a flow path body 82 connected to the air bag 81 by fluid, and a connection portion 83 such as a pipe joint provided on the flow path body 82. In the air bag 81 and the flow path body 82, a plurality of sheet members are formed into a bag shape by heat welding or the like. The sheet members forming the air bag 81 and the flow path body 82 are formed of, for example, a thermoplastic elastomer. Here, as the thermoplastic elastomer, for example, TPU is used.

[0098] Here, the air bag 81 refers to a bag-like structure. In this embodiment, the blood pressure measurement device 1 uses air through the pump 14, so the air bag is used for description. However, when a fluid other than air is used, the bag-like structure may also be a fluid bag inflated by the fluid. The air bag 81 is configured as a rectangle that is long in one direction.

[0099] The flow path body 82 is provided integrally with a portion of an edge portion in the long dimension direction of the air bag 81, for example. The flow path body 82 is formed by a portion of two sheet members among the plurality of sheet members forming the air bag 81. In addition, the flow path body 82 is formed in a shape that is long in one direction with a width smaller than the width in the short dimension direction of the air bag 81. The flow path body 82 is provided integrally with a connection portion 83 at the top end. The flow path body 82 is connected to the fluid circuit 24 via the connection portion 83, and constitutes a flow path between the fluid circuit 24 and the air bag 81. The thickness of the flow path body 82 when inflated is smaller than the thickness of the air bag 81 when inflated.

[0100] A plurality of connection parts 83 are provided. The plurality of connection parts 83 are connected to a plurality of hole parts 31 b 3 formed at the end of the bottom part 31 b on the side where the first cuff structure 4 protrudes. The plurality of connection parts 83 are connected to the fluid circuit 24 .

[0101] Below, use Figures 1 to 3 , Figure 5 A specific example of the second cuff structure 5 will be described. Figures 1 to 3 , Figure 5 As shown, the second cuff structure 5 includes a second collar 61 and a second pressing cuff 62. The second cuff structure 5 is formed by sequentially stacking the second collar 61 and the second pressing cuff 62 toward the wrist 300.

[0102] The second collar 61 is fixed, for example, at one end to the bottom 31b provided on the wrist 300 side of the housing 11. The second collar 61 is formed into a band shape that is bent into a shape that follows the circumferential direction of the wrist 300. The second collar 61 is made of a resin material. The second collar 61 is formed of a material with low hardness that has flexibility and shape retention. Here, flexibility means that the shape is deformed in the radial direction when an external force from the strap 6 is applied to the second collar 61. Shape retention means that the second collar 61 can maintain a pre-given shape when no external force is applied. That is, the second collar 61 is formed of a resin material with a hardness that does not cause compression deformation or hardly causes compression deformation, but can cause elastic deformation such as bending deformation in which the curvature of the shape, especially the curved portion, changes. Therefore, the second collar 61 is formed so as to be elastically deformable in the following manner: by being bent by an external force, the internal space for the wrist 300 to be arranged is enlarged or reduced in accordance with the shape of the wrist to be worn. For example, the second collar 61 is formed of thermoplastic polyurethane resin (hereinafter referred to as TPU) or polypropylene resin.

[0103] Furthermore, one end side of the second collar 61 is fixed to the housing 11. Furthermore, the second collar 61 is formed to have a length such that when the blood pressure measurement device 1 is worn on the wrist 300 of the user with the longest circumference, the second collar 61 faces at least one of the two arteries 311 and 312, and the end side overlaps with the first cuff structure 4. Here, one of the two arteries 311 and 312 is the radial artery 311, and the other is the ulnar artery 312. Preferably, the second collar 61 is formed to have a length such that when the blood pressure measurement device 1 is worn on the wrist 300 of the user with the longest circumference, the second collar 61 is set to have a length such that the other end does not contact the device body 3 when the blood pressure measurement device 1 is worn on the wrist 300 of the user with the shortest circumference. For example, the portion of the second collar 61 extending from the housing 11 of the device body 3 is curved at a predetermined radius of curvature to follow the shape of the side of one of the left and right wrists 300 and the palm side of the wrist 300 .

[0104] The second pressing cuff 62 is fixed to the inner circumferential surface of the second clamp ring 61 by double-sided tape, adhesive, heat fusion, etc. The second pressing cuff 62 is fluidically connected to the pump 14 via the fluid circuit 24. One main surface of the second pressing cuff 62 is fixed to the inner surface of the second clamp ring 61. The second pressing cuff 62 presses the opposing wrist 300 by expanding, and presses the overlapped first cuff structure 4 toward the wrist 300. The thickness of the second pressing cuff 62 when expanded is the same as or greater than the thickness of the first pressing cuff 52 when expanded.

[0105] The second compression cuff 62 includes, for example, a single or multiple air bags 91, a flow path body 92 provided at the end of the air bag 91, and a connection portion 93 such as a pipe joint provided at the flow path body 92 and connected to the fluid circuit 24. Here, the air bag 91 refers to a bag-shaped structure. In this embodiment, the blood pressure measurement device 1 is configured to use air through the pump 14, so an air bag is used for description. However, when a fluid other than air is used, the bag-shaped structure can be any fluid bag that is expanded by the fluid. The air bag 91 is formed in a rectangular bag shape that is long in one direction.

[0106] In the air bag 91, a plurality of sheet members are formed into a bag shape by heat welding or the like. For example, when the second pressing cuff 62 is configured to have a plurality of air bags 91, the plurality of air bags 91 are stacked and integrated by welding or the like, and are fluidically continuous. The sheet member forming the air bag 91 is formed of, for example, a thermoplastic elastomer. Here, the thermoplastic elastomer is, for example, TPU.

[0107] The flow path body 92 is provided integrally with a part of an edge portion in the long dimension direction of the air bag 91, for example. The flow path body 92 is formed by a part of two sheet members among the plurality of sheet members forming the air bag 91. In addition, the flow path body 92 is formed in a shape that is long in one direction with a width smaller than the width in the short dimension direction of the air bag 91. The flow path body 92 is provided integrally with a connection portion 93 at the top end. The flow path body 92 is connected to the fluid circuit 24 via the connection portion 93, and constitutes a flow path between the fluid circuit 24 and the air bag 91. The thickness of the flow path body 92 when inflated is smaller than the thickness of the air bag 91 when inflated.

[0108] For example, a plurality of connection portions 93 are provided. The plurality of connection portions 93 are connected to the fluid circuit 24 via a plurality of holes 31 b 3 formed in the bottom portion 31 b.

[0109] Note that, for example, the connection portion 93 is connected to any one or more of the plurality of holes 31 b 3 formed at the end of the bottom portion 31 b on the side where the second cuff structure 5 protrudes.

[0110] The first pressing cuff 52 and the second pressing cuff 62 of the first cuff structure 4 and the second cuff structure 5 thus constructed are formed to have such lengths that when the blood pressure measurement device 1 is worn on the wrist 300 having the maximum circumference, the inflated portion of the air bag 71 of the first pressing cuff 52 covers at least one of the two arteries 311 and 312, and the air bag 91 of the second pressing cuff 62 can overlap with the air bag 71. Furthermore, the air bag 91 of the second pressing cuff 62 is formed to have such lengths that when the blood pressure measurement device 1 is worn on the wrist 300 having the maximum circumference and the air bag 91 overlaps with the air bag 71 of the first pressing cuff 52, the end edge of the air bag 91 on the side opposite to the flow path body 92 does not overlap with the air bag 71 of the first pressing cuff 52 on the artery covered by the air bag 71 of the first pressing cuff 52. That is, the air bag 91 of the second compression cuff 62 is set to the following length: when the blood pressure measurement device 1 is worn on the wrist 300 with the maximum circumference and the air bag 91 overlaps with the air bag 71 of the first compression cuff 52, the inflated portion of the air bag 91 of the second compression cuff 62 overlaps with the air bag 71 of the first compression cuff 52 on the artery covered by the air bag 71 of the first compression cuff 52.

[0111] The strap 6 is formed in a belt shape on the outer peripheral side of the first cuff structure 4 and the second cuff structure 5 on the opposite side to the wrist 300. The strap 6 is not fixed to the first cuff structure 4 and the second cuff structure 5. One end of the strap 6 is fixed to the ring portion 31c on one side. In addition, the strap 6 has a pair of hook and loop fasteners 6a formed with a hook on one side and a loop on the other side, and the strap 6 with the end side inserted into the ring portion 31c on the other side is fixed by engaging them with each other. In addition, the strap 6 has a handle 6b at the other end to make it easy for the user to grasp.

[0112] For example, the strap 6 is fixed to the loop portion 31c formed on the side extending from the second cuff structure 5, and is inserted into the loop portion 31c formed on the side extending from the first cuff structure 4, and then folded back. The strap 6 has a length that allows it to be inserted into the loop portion 31c provided on the contour housing 31 when the blood pressure measurement device 1 is worn on a wrist 300 with a maximum circumference assumed to be worn. In addition, the hook and loop fastener 6a is provided on the strap 6 with a length and configuration that allows the strap 6 to be folded back and fastened on a wrist 300 with a maximum circumference and a minimum circumference assumed to be worn. By stretching the end of the strap 6 after the loop portion 31c is folded back in a direction away from the loop portion 31c, as shown in FIG. Figure 3As shown, the blood pressure measurement device 1 is mounted on the wrist 300 in a state where the first cuff structure 4 and the second cuff structure 5 are wrapped around the wrist 300. By fixing the band 6 with the hook and loop fastener 6a, the movement of the first pressing cuff 52 and the second pressing cuff 62 to expand outwardly on the side opposite to the wrist is restricted, so that the first pressing cuff 52 and the second pressing cuff 62 can compress the wrist. Thus, the blood pressure measurement device 1 can perform blood pressure measurement based on the well-known oscillometric method.

[0113] Next, use Figures 10 to 12 An example of the fluid structure of the fluid circuit 24 of the blood pressure measurement device 1 thus constructed will be described. It should be noted that, in this example, there is one connection portion 73 of the first pressing cuff 52, three connection portions 83 of the sensing cuff 54, and three connection portions 93 of the second pressing cuff 62.

[0116] The first internal flow path 241 connects the pump 14 with the first pressing cuff 52 and the second pressing cuff 62. The first internal flow path 241 is a flow path that branches into three. The second internal flow path 242 connects the second pressing cuff 62 and the valve 16. The third internal flow path 243 connects the second pressing cuff 62 and the first flow path obstruction 24b1. The fourth internal flow path 244 connects the first flow path obstruction 24b1 and the sensing cuff 54. The fifth internal flow path 245 connects the sensing cuff 54 and the pressure sensor 17. The sixth internal flow path 246 connects the sensing cuff 54 and the second flow path obstruction 24b2. The seventh internal flow path 247 connects the second flow path obstruction 24b2 and the atmosphere, and sets the secondary side of the second flow path obstruction 24b2 to be open to the atmosphere.

[0117] These multiple internal flow paths 241 to 247 are formed in the flow path plate 24 a as independent flow paths.

[0118] The flow path plate 24a has, for example, a first port 24a1 connected to the pump 14, a second port 24a2 connected to the valve 16, a third port 24a3 connected to the pressure sensor 17, and a fourth port 24a4 open to the atmosphere. For example, the first port 24a1 to the fourth port 24a4 are provided on the upper surface of the flow path plate 24a, that is, the main surface of the flow path plate 24a on the windshield 32 side.

[0119] The first port 24a1 is formed at one of the three ends of the first internal flow path 241. The second port 24a2 is formed at one end of the second internal flow path 242. The third port 24a3 is formed at one end of the fifth internal flow path 245. The fourth port 24a4 is formed at one end of the seventh internal flow path 247.

[0120] The flow channel plate 24a has a plurality of ports 24c selectively connected to or sealed with the cuffs of the first cuff structure 4 and the second cuff structure 5 and the inspection machine. The plurality of ports 24c are arranged to face the plurality of holes 31b3 formed in the bottom 31b of the outer shell 31.

[0121] For example, the plurality of ports 24c include: one fifth port 24c1 connectable to the connection portion 73 of the first pressing cuff 52, three sixth ports 24c2 connectable to the three connection portions 93 of the second pressing cuff 62, and three seventh ports 24c3 connectable to the three connection portions 83 of the sensing cuff 54. For example, the fifth port 24c1 to the seventh port 24c3 are provided on the lower surface of the flow path plate 24a, that is, the main surface on the bottom 31b side of the flow path plate 24a.

[0122] The fifth port 24c1 is formed at an end different from the end connected to the first port 24a1 among the three ends of the first internal flow path 241. The three sixth ports 24c2 are respectively formed at an end different from the end connected to the first port 24a1 and the fifth port 24c1 among the three ends of the first internal flow path 241, the other end of the second internal flow path 242, and the other end of the third internal flow path 243. The three seventh ports 24c3 are formed at the other end of the fourth internal flow path 244, the other end of the fifth internal flow path 245, and the other end of the sixth internal flow path 246.

[0123] The plurality of ports 24c are formed so as to be selectively connectable to the connection portions 73, 83, 93 of the cuffs 52, 54, 62 and various inspection machines. The plurality of ports 24c are formed so as to be sealable.

[0124] Next, as the blood pressure measurement device 1, use Fig.11The structure of the fluid circuit 24 connected to the first cuff structure 4 and the second cuff structure 5 will be described. The connection portion 73 of the first pressing cuff 52 is fixed to the fifth port 24c1, and the connection portion 93 of the second pressing cuff 62 is fixed to one sixth port 24c2. Thus, the first pressing cuff 52 and the second pressing cuff 62 are connected to the pump 14 via the first internal flow path 241 of the flow path plate 24a.

[0125] The second pressing cuff 62 is connected to the valve 16 via the second internal flow path 242 of the flow path plate 24a by fixing the connecting portion 93 to one of the sixth ports 24c2. The second pressing cuff 62 is connected to the first flow path blocker 24b1 via the third internal flow path 243 of the flow path plate 24a by fixing the connecting portion 93 to one of the sixth ports 24c2.

[0126] The sensing cuff 54 is connected to the first flow path blocker 24b1 via the fourth internal flow path 244 of the flow path plate 24a by fixing the connection portion 83 to one of the seventh ports 24c3. Thus, the sensing cuff 54 is connected to the second pressing cuff 62 via the first flow path blocker 24b1. In addition, the sensing cuff 54 is connected to the pressure sensor 17 via the fifth internal flow path 245 of the flow path plate 24a by fixing the connection portion 83 to one of the seventh ports 24c3. In addition, the sensing cuff 54 is connected to the second flow path blocker 24b2 via the sixth internal flow path 246 of the flow path plate 24a by fixing the connection portion 83 to one of the seventh ports 24c3, thereby connecting the sensing cuff 54 to the atmosphere via the second flow path blocker 24b2. Here, the first flow path blocker 24b1 between the first pressing cuff 52 and the sensing cuff 54 and the second flow path blocker 24b2 between the sensing cuff 54 and the atmosphere are set to provide a desired pressure difference between the first pressing cuff 52 and the sensing cuff 54 .

[0127] Next, use Fig.12 Next, the configuration of the fluid circuit 24 in which the blood pressure measurement device 1 and the inspection machine are connected when inspecting each component will be described.

[0128] One of the fifth port 24c1 and the sixth port 24c2 connected to the first internal flow path 241 is sealed, and the other is connected to a pump inspection machine 401 for inspecting the performance of the pump 14. Fig.12 In the example shown in FIG. 1 , the fifth port 24c1 is sealed and the pump inspection machine 401 is connected to the sixth port 24c2. Thus, the pump inspection machine 401 is connected only to the pump 14 via the first internal flow path 241, so that the pump 14 can be inspected.

[0129] The sixth port 24c2 connected to the second internal flow path 242 is connected to a valve inspection machine 402 for inspecting the valve 16. Thus, the valve inspection machine 402 is connected only to the valve 16 via the second internal flow path 242, so that the valve 16 can be inspected.

[0130] The sixth port 24c2 connected to the third internal flow path 243 is connected to the first flow path obstruction member inspection machine 403 for inspecting the first flow path obstruction member 24b1, and the seventh port 24c3 connected to the fourth internal flow path 244 is open to the atmosphere. Thus, the first flow path obstruction member inspection machine 403 is connected to the atmosphere via the first flow path obstruction member 24b1 through the third internal flow path 243 and the fourth internal flow path 244, so that the first flow path obstruction member 24b1 can be inspected.

[0131] The seventh port 24c3 connected to the fifth internal flow path 245 is connected to a sensor inspection machine 404 for inspecting the pressure sensor 17. Thus, the sensor inspection machine 404 is connected only to the pressure sensor 17 via the fifth internal flow path 245, and thus the pressure sensor 17 can be inspected.

[0132] The seventh port 24c3 connected to the sixth internal flow path 246 is connected to the second flow path obstruction member inspection machine 405 for inspecting the second flow path obstruction member 24b2, and the fourth port 24a4 connected to the seventh internal flow path 247 is open to the atmosphere. Thus, the second flow path obstruction member inspection machine 405 is connected to the atmosphere via the second flow path obstruction member 24b2 through the sixth internal flow path 246 and the seventh internal flow path 247, and can inspect the second flow path obstruction member 24b2.

[0133] In this way, the various inspection machines 401 to 405 are connected to the inspection object via the internal flow paths 241 to 247, respectively, so that the inspection object can be inspected independently. In addition, the various inspection machines 401 to 405 can be connected to the multiple ports 24c connected to the cuffs 52, 54, and 62, and the connection is easy. That is, the multiple ports 24c can selectively connect the cuffs 52, 54, 62 and the inspection machines 401 to 405, and the disassembly and sealing of the cuffs 52, 54, 62 and the inspection machines 401 to 405 are easy during blood pressure measurement and inspection.

[0134] Next, an example of the power transmission device 100 for transmitting power to the charging circuit unit 21 of the device body 3 will be described.

[0135] like Figure 4As shown, the power transmission device 100 includes a power supply 101, a power transmission unit 102, an antenna unit 103, and a power transmission terminal 104. It should be noted that the power transmission device 100 may also be a structure including one of the antenna unit 103 and the power transmission terminal 104. The power supply 101 is, for example, an AC adapter connected to a commercial power supply. The power supply 101 converts AC power input from the commercial power supply into DC power and supplies the DC power to the power transmission unit 102.

[0136] Transmitter 102 generates AC power as transmission power from DC power supplied from power source 101, and supplies the power to antenna 103. Transmitter 102 generates AC power having the same or substantially the same frequency as the resonance frequency of the transmission resonance circuit of antenna 103, for example.

[0137] The antenna unit 103 is, for example, a power transmission coil as a power transmission resonance circuit. The power transmission surface of the antenna unit 103 is formed in a planar shape. The antenna unit 103 transmits power to the antenna unit 211 of the device body 3. The antenna unit 103 includes, for example, a resonant capacitor, and constitutes a power transmission resonance circuit.

[0138] The power transmission terminal 104 is formed so as to be contactable with a charging terminal 214 provided in the device body 3 and is fixed to the charging terminal 214 .

[0139] In the blood pressure measuring device 1 thus constructed, a plurality of internal flow paths 241 to 247 formed in the flow path plate 24a of the flow path plate unit (fluid circuit) 24 respectively connect the pump 14 with the first pressing cuff 52 and the second pressing cuff 62, the valve 16 with the second pressing cuff 62, the second pressing cuff 62 with the first flow path blocker 24b1, the first flow path blocker 24b1 with the sensing cuff 54, the pressure sensor 17 with the sensing cuff 54, the sensing cuff 54 with the second flow path blocker 24b2, and the second flow path blocker 24b2 with the atmosphere. In addition, the internal flow paths 241 to 247 are respectively independent. Therefore, when the blood pressure measuring device 1 is in a usable state in which the blood pressure can be measured, the flow path plate unit 24 can connect the pump 14, the valve 16, and the pressure sensor 17 as components with the cuffs 52, 54, and 62. Furthermore, during the manufacture and maintenance of the blood pressure measurement device 1, when inspecting the inspection status of each component 14, 16, 17, the components 14, 16, 17 and the inspection devices 401 to 405 can be connected, and when not inspecting, they can be sealed or opened to the atmosphere. Therefore, the blood pressure measurement device 1 can inspect the pump 14, valve 16, and pressure sensor 17 provided in the flow path plate unit 24 individually without increasing the size of the flow path plate 24a as the flow path plate unit 24, which has the flow path blockers 24b1 and 24b2 provided therein.

[0140] In addition, the blood pressure measurement device 1 can respectively connect the second pressing cuff 62 and the first flow path blocker 24b1, the first flow path blocker 24b1 and the sensing cuff 54, the sensing cuff 54 and the second flow path blocker 24b2, and the second flow path blocker 24b2 and the atmosphere through the third internal flow path 243, the fourth internal flow path 244, the sixth internal flow path 246, and the seventh internal flow path 247. Therefore, the blood pressure measurement device 1 connects the first flow path blocker inspection machine 403 and the second flow path blocker inspection machine 405 to the third internal flow path 243 and the sixth internal flow path 246, respectively, and sets the fourth internal flow path 244 to be open to the atmosphere, thereby also being able to inspect the first flow path blocker 24b1 and the second flow path blocker 24b2.

[0141] In addition, the flow path plate 24a is configured to have a plurality of ports 24c that can selectively connect the connection parts 73, 83, 93 of the cuffs 52, 54, 62, and the inspection machines 401 to 405. That is, the flow path plate 24a is not provided with ports for connecting the cuffs 52, 54, 62 and the inspection machines 401 to 405, but the plurality of ports 24c can be used for both blood pressure measurement and inspection, thereby preventing the size from becoming larger, and making it easier to seal and open to the atmosphere. That is, the blood pressure measurement device 1 can selectively connect the cuffs 52, 54, 62, the inspection machines 401 to 405, and the sealing plugs to the ports 24c through the hole 31b3 in a state where the cuff cover 33 is removed, thereby simplifying the internal flow paths 241 to 247 and achieving high operability.

[0142] In addition, the blood pressure measurement device 1 is provided with a first cuff structure 4 and a second cuff structure 5 extending from the device body 3 and connected to each other by fluid on both sides in one direction of the device body 3. In addition, the device body 3 has a protrusion (sensor portion) 31b1 as a space for arranging at least one of the biosensor 20 and the charging terminal 214 at a position separated from the first cuff structure 4 and the second cuff structure 5, for example, at the center of the bottom 31b, on the bottom 31b of the housing 11 as the back side. Thus, the first cuff structure 4 and the second cuff structure 5, and at least one of the biosensor 20 and the charging terminal 214 can be arranged on the back side of the device body 3.

[0143] In addition, the first cuff structure 4 and the second cuff structure 5 are fluidically connected via the fluid circuit 24 including the flow path plate 24a. It should be noted that the first cuff structure 4 and the second cuff structure 5 can also be directly fluidically connected to the first cuff structure 52 and the second cuff structure 62. Through these configurations, even if the first cuff structure 4 and the second cuff structure 5 are provided and fixed to the housing 11 in one direction separately, the first cuff structure 4 and the second cuff structure 5 can be fluidically connected.

[0144] In addition, when the blood pressure measuring device 1 is worn on a wrist 300 having a maximum circumference, the air bag 71 of the first compression cuff 52 covers an area where at least one of the two arteries 311 and 312 exists, and the air bag 91 of the second compression cuff 62 can overlap with at least a portion of the air bag 71 of the first compression cuff 52.

[0145] Therefore, the wrist 300 can be compressed by the first compression cuff 52 and the second compression cuff 62 , so even if the air bag 71 of the first compression cuff 52 and the air bag 91 of the second compression cuff 62 are not arranged on the back side of the device body 3 , sufficient compression force can be ensured to compress the artery.

[0146] Thus, in the blood pressure measurement device 1, when the blood pressure measurement device 1 is worn on the wrist 300 with the maximum circumference assumed to be worn, the air bag 71 of the first pressing cuff 52 and the air bag 91 of the second pressing cuff 62 can overlap by a predetermined length. In addition, when the blood pressure measurement device 1 is worn on the wrist 300 with the minimum circumference, the first cuff structure 4 and the second cuff structure 5 have a length that does not contact the device body 3. In addition, the first cuff structure 4 and the second cuff structure 5 are not directly connected to the strap 6.

[0147] With these configurations, in the blood pressure measurement device 1, the air bag 71 of the first pressing cuff 52 and the air bag 91 of the second pressing cuff 62 overlap and expand, so that the artery can be appropriately pressed by the first pressing cuff 52 and the second pressing cuff 62. Therefore, the blood pressure measurement device 1 can arrange the biosensor 20 on the back side of the device body 3, and even if the air bag 71 of the first pressing cuff 52 and the air bag 91 of the second pressing cuff 62 are not arranged on the back side of the device body 3, it is possible to perform blood pressure measurement with good accuracy.

[0148] In addition, the housing 11 has a vent 31b6 covered by a waterproof and breathable sheet 31b7 at the bottom 31b, so that ventilation can be performed in the housing 11. In addition, by arranging the vent 31b6 at a position separated from the first cuff structure 4 and the second cuff structure 5 at a position other than the protruding portion 31b1 of the bottom 31b, it is possible to prevent the vent 31b6 from being blocked by the first cuff structure 4 and the second cuff structure 5. In addition, by arranging the vent 31b6 at a position covered by the cuff cover 33 arranged with a gap from the bottom 31b, the vent 31b6 is protected by the cuff cover 33. Therefore, the blood pressure measurement device 1 can prevent dirt from adhering to the vent 31b6 and the waterproof and breathable sheet 31b7, and can prevent the ventilation function from being impaired.

[0149] Furthermore, the ends of the first cuff structure 4 and the second cuff structure 5 disposed at the bottom 31b of the housing 11 are covered by the cuff cover 33, so that the movement of the first cuff structure 4 and the second cuff structure 5 in a direction away from the bottom 31b is restricted by the cuff cover 33. Therefore, the first cuff structure 4 and the second cuff structure 5 can be prevented from being easily separated from the device body 3.

[0150] In addition, the blood pressure measurement device 1 is configured such that various sensors 20a to 20c as the biosensor 20 and the charging terminal 214 are provided at the bottom 31b of the device body 3. Therefore, the device body 3 does not need to provide the biosensor 20 and the charging terminal 214 at a position away from the device body according to the substrate 25 provided inside the housing 11, which can simplify wiring and the degree of freedom of configuration is high. In addition, the biosensor 20 is provided in the housing 11 with high rigidity, and when the blood pressure measurement device 1 is worn on the wrist 300, it can stably contact the wrist 300, so that the biosensor 20 can appropriately acquire biological information. In addition, by providing the charging terminal 214 at the bottom 31b, when the blood pressure measurement device 1 is removed from the wrist 300, the charging terminal 214 is exposed to the outside, so that charging using the charging terminal 214 becomes easy.

[0151] Furthermore, in the blood pressure measurement device 1 , the first pressing cuff 52 and the second pressing cuff 62 are fluidically connected via the fluid circuit 24 provided in the device body 3 , thereby simplifying the arrangement of the first pressing cuff 52 and the second pressing cuff 62 at the bottom 31 b .

[0152] In the blood pressure measurement device 1 thus configured, the pump 14 , valve 16 , pressure sensor 17 , first flow path blocker 24 b 1 , and second flow path blocker 24 b 2 , which are components provided in the flow path plate unit 24 , can be individually inspected by the inspection machines 401 to 405 without increasing the size of the flow path plate unit 24 .

[0153] It should be noted that the present invention is not limited to the above-mentioned embodiments. For example, in the above-mentioned example, the following example is described: the flow path plate unit 24 as a fluid circuit sets the first internal flow path 241 connecting the pump 14, the first pressing cuff 52 and the second pressing cuff 62, and the third internal flow path 243 connecting the second pressing cuff 62 and the first flow path blocker 24b1 as independent flow paths, and sets the fourth internal flow path 244 connecting the first flow path blocker 24b1 and the sensing cuff 54, and the sixth internal flow path 246 connecting the sensing cuff 54 and the second flow path blocker 24b2 as independent flow paths.

[0154] However, if Figures 13 to 16 As shown, the flow path plate unit 24 may also be configured to have an eighth internal flow path 241, 243 in which the first internal flow path 241 and the third internal flow path 243 are integrated, and a ninth internal flow path 244, 246 in which the fourth internal flow path 244 and the sixth internal flow path 246 are integrated.

[0155] In the blood pressure measurement device 1 of such a configuration, the first pressing cuff 52 has one connection portion 73, the sensing cuff 54 has two connection portions 83, and the second pressing cuff 62 has two connection portions 93. Fig.14 As shown, the connection parts 83 of the sensing cuff 54 can be set to two, and the connection parts 93 of the second compression cuff 62 can be set to two, and as shown in FIG. Fig.13 and Fig.14 As shown, the sixth port 24c2 and the seventh port 24c3 are provided in two.

[0156] For example, Fig.14 As shown, the eighth internal flow paths 241 and 243 are connected to the pump 14, the first pressing cuff 52, the second pressing cuff 62, and the first flow path blocking member 24b1 via the first port 24a1, the fifth port 24c1, and the sixth port 24c2. Fig.14 As shown, the ninth internal flow paths 244 and 246 are connected to the first flow path blocker 24 b 1 , the second flow path blocker 24 b 2 and the sensing cuff 54 via the seventh port 24 c 3 .

[0157] In addition, when checking the pump 14, if Fig.15 As shown, it is sufficient to connect the pump inspection machine 401 to one of the fifth port 24c1 and the sixth port 24c2 connected to the eighth internal flow path 241, 243, and seal the other of the fifth port 24c1 and the sixth port 24c2, the seventh port 24c3 connected to the ninth internal flow path 244, 246, and the fourth port 24a4 open to the atmosphere. In addition, when inspecting the first flow path obstruction member 24b1 and the second flow path obstruction member 24b2, as shown in FIG. Fig.16As shown, as long as the first flow path obstruction component inspection machine 403 is connected to one of the fifth port 24c1 and the sixth port 24c2 connected to the eighth internal flow path 241, 243, and the other of the fifth port 24c1 and the sixth port 24c2 are sealed, the second flow path obstruction component inspection machine 405 is connected to the seventh port 24c3 connected to the ninth internal flow path 244, 246, pressure is applied from the first port 24a1 by the pump 14, and the fourth port 24a4 is set to be open to the atmosphere.

[0158] According to the blood pressure measurement device 1 having such a configuration, the number of connection points between the flow path plate unit 24 and the cuffs 54 and 62 can be reduced, and the pump 14, valve 16, and pressure sensor 17 can be inspected. In addition, the resistance values ​​of the first flow path obstruction member 24b1 and the second flow path obstruction member 24b2 can be obtained based on the pressure difference measured by the first flow path obstruction member inspection machine 403 and the second flow path obstruction member inspection machine 405.

[0159] In the above example, the pump 14 has a valve mechanism as an on-off valve, but the present invention is not limited thereto, and the pump 14 may also have a valve mechanism without the valve mechanism. Figures 17 to 19 2 shows an example of using the flow channel plate unit 24 in a case where the pump 14 has a configuration without a valve mechanism.

[0160] For example, when the pump 14 is configured not to have a valve mechanism, the blood pressure measurement device 1 includes, for example, two valves 16 and two pressure sensors 17. Fig.17 and Fig.18 As shown, the flow path plate unit 24 has two second ports 24a2 and two third ports 24a3, including two independent second internal flow paths 242 and two independent fifth internal flow paths 245, and has four sixth ports 24c2 and four seventh ports 24c3. In addition, the sensing cuff 54 has four connecting portions 83, and the second pressing cuff 62 has four connecting portions 93.

[0161] Furthermore, during inspection, in the blood pressure measurement device 1, the valve inspection machines 402 are connected to the two second internal flow paths 242, and the sensor inspection machines 404 are connected to the two fifth internal flow paths 245. In this way, the blood pressure measurement device 1 may be used in which the pump 14 has no valve mechanism.

[0162] In the above example, the configuration of the flow path plate 24a having a plurality of ports 24c to which the cuffs 52, 54, 62 and the inspection machines 401 to 405 are selectively connected is described, but the arrangement of the plurality of ports 24c can be set appropriately. However, it is preferable to centrally arrange the plurality of ports 24c for each cuff 52, 54, 62 to be connected, because the shapes of the flow path bodies 72, 82, 92 of the cuffs 52, 54, 62 can be simplified.

[0163] In the above-mentioned example, an example in which the band 6 is not fixed to the first cuff structure 4 and the second cuff structure 5 is described. However, a configuration in which the band 6 is fixed to the second cuff structure 5 that becomes the outer side when the first cuff structure 4 and the second cuff structure 5 are overlapped may be adopted. That is, even if the band 6 is fixed to the second cuff structure 5, if the first cuff structure 4 that is closer to the wrist 300 than the second cuff structure 5 is not fixed to the band 6, when the band 6 is fastened, the first cuff structure 4 and the second cuff structure 5 can be fastened and closely attached to the wrist 300.

[0164] In the above example, the device body 3 adopts a configuration in which the PPG sensor 20a, the SpO2 sensor 20b, and the ECG sensor 20c are provided on the bottom 31b of the outer shell 31 forming the back side of the housing 11 as the biosensor 20. However, the biosensor 20 may be any one of the PPG sensor 20a, the SpO2 sensor 20b, and the ECG sensor 20c, and may also be configured to have a sensor for acquiring other biometric information in addition to or in place of these sensors 20a to 20c.

[0165] That is, the present invention is not limited to the above-mentioned embodiments, and various modifications can be made in the implementation stage without departing from the scope of the main purpose. In addition, the various embodiments can also be implemented in combination as much as possible, in which case, the effect of the combination can be obtained. Moreover, the above-mentioned embodiments include inventions at various stages, and various inventions can be extracted by appropriate combinations of the disclosed multiple constituent elements. It should be noted that the present invention is not limited to the above-mentioned embodiments, and various modifications can be made in the implementation stage without departing from the main purpose. In addition, the various embodiments can also be implemented in combination as much as possible, in which case, the effect of the combination can be obtained. Moreover, the above-mentioned embodiments include various inventions, and various inventions can be extracted by combinations selected from the disclosed multiple constituent elements. For example, in the case where the problem can be solved and the effect can be obtained even if some constituent elements are deleted from all the constituent elements shown in the embodiment, the structure in which the constituent element is deleted can be extracted as an invention.
