Description

[Technical field]

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

[0002] In recent years, blood pressure measuring devices used for measuring blood pressure are used as a means for checking health conditions not only in medical facilities but also at home. For example, blood pressure measuring devices measure blood pressure by inflating and deflating a cuff wrapped around the upper arm or wrist of a living body and detecting the pressure of the cuff with a pressure sensor, thereby detecting the vibration of the arterial wall.

[0003] Also, as a blood pressure measuring device, a wearable blood pressure monitor that is worn on the wrist is known (see, for example, Patent Document 1). In such a wearable blood pressure monitor, the air bag and curler are joined, but the curler and band are not joined. This means that there is a risk of misalignment between the curler and the band. If misalignment occurs, there will be areas where the air bag and curler cannot be held down by the band, which may lead to reduced measurement accuracy and deterioration of the air bag. Also, insert material is sometimes used to reinforce the band, but this increases the manufacturing costs of the band.

[0004] Also known is a general wrist-type blood pressure measuring device in which an air bag, curler, and air bag are placed in a cloth bag made up of an inner cloth and an outer cloth to prevent positional shifting (see, for example, Patent Document 2). [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2006-174860 A [Patent Document 2] JP 2020-65651 A Summary of the Invention [Problem to be solved by the invention]

[0006] In a blood pressure measuring device in which the curler and the air bag are disposed inside a cloth bag, the inner cloth needs to be made of a material that is easy to stretch so as not to hinder the inflation of the air bag. For this reason, if the blood pressure measuring device is to be worn on the wrist, the radius of curvature becomes small when worn, and large sagging and wrinkles occur in the inner cloth, which leads to a poor appearance.

[0007] SUMMARY OF THE PRESENT DISCLOSURE An object of the present invention is to provide a blood pressure measuring device that can prevent misalignment between the band, curler, and fluid bag, has a good appearance, and is highly accurate. [Means for solving the problem]

[0008] According to one aspect, there is provided a blood pressure measuring device comprising: a device body; a curler fixed to the device body; a fluid bag fixed to an inner surface of the curler and inflated with a fluid; and a band having a hook-and-loop fastener on its outer surface, the band being integral with an outer surface of the curler or with an outer surface of the curler and an outer surface of the fluid bag.

[0009] According to this embodiment, since the band is formed integrally with the outer surface of the curler or the band is formed integrally with the outer surfaces of the curler and the fluid bag, it is possible to prevent misalignment between the band that tightens the fluid bag against the living body and the curler and / or the fluid bag. Therefore, the blood pressure measurement device can stably press the fluid bag against the living body, which stabilizes the accuracy of blood pressure measurement and prevents deterioration of the fluid bag. Furthermore, since the band is configured to be provided on the outer peripheral surface of curler 51, it is possible to prevent sagging and wrinkles, and therefore the blood pressure measurement device can obtain a high appearance.

[0010] In the cuff structure according to the above aspect, the curler is formed to be longer than a longitudinal length of the fluid bag and is formed to be elastically deformable following a circumferential shape of a part of a living body to which the curler is attached, A blood pressure measuring device is provided, wherein the band is provided on an outer circumferential surface of the curler and extends from one end of the curler.

[0011] According to this aspect, the curler elastically deforms to follow the shape of the living body, and the band can fix the curler by the pair of hook-and-loop fasteners, so that the fluid bag can be pressed against the living body.

[0012] A blood pressure measuring device is provided in the above-mentioned one aspect of the cuff structure, wherein the curler is formed from a low hardness material and has a fixed portion into which a high hardness material having a hardness higher than that of the low hardness material is inserted and fixed to the device body, and the band is formed from a material which is less stretchable than the curler.

[0013] According to this aspect, even if the curler is made of a material with a relatively low hardness, when the fluid bag is pressed toward the living body by the band and then fastened by the hook-and-loop fastener, the curler can be bent and deformed in accordance with the living body. In addition, the curler is configured such that the outer circumferential surface is covered by a band made of a material that is less stretchable than the curler. This makes it possible to suppress the curler from deforming radially outward when the fluid bag expands. Therefore, the curler easily elastically deforms in accordance with the shape of the living body, and the curler is suppressed from deforming radially outward during blood pressure measurement, making it possible to efficiently press the fluid bag toward the living body.

[0014] In addition, since the curler is formed by inserting a high-hardness material that is harder than the material forming the curler into the fixed portion that is fixed to the device body, the strength of the fixed portion that is attached to the device body can be improved.

[0015] There is provided a blood pressure measuring device according to the above-mentioned one aspect of the cuff structure, wherein the device body has a loop portion for folding back the band.

[0016] According to this aspect, the curler of the band can be easily fastened, and the fluid bag can be stably attached to the living body.

[0017] There is provided a blood pressure measuring device in the above-mentioned one aspect of the cuff structure, wherein both ends of the curler are such that one of the curlers overlaps the other when the cuff structure is attached to a living body having at least the smallest circumferential length of the living body to which the cuff is intended to be attached.

[0018] According to this aspect, one of the ends of the curler overlaps the other, so that the fluid bag can be in contact with the living body regardless of whether the blood pressure measuring device is attached to a living body having a different circumferential length. That is, in the blood pressure measuring device, both ends of the curler abut in the circumferential direction, preventing a gap from occurring between the living body and the fluid bag, and enabling the fluid bag to be in close contact with the living body.

[0019] In the blood pressure measurement device of the above aspect of the cuff structure, one end of the curler has a smaller radius of curvature than the other end of the curler that overlaps the one end.

[0020] According to this aspect, since the other end of the curler is located radially outward from the one end before fastening with the band, the other end of the curler can be located outside the one end when fastening with the band. Therefore, when the curler is fastened with the band, the ends of the blood pressure measurement device tend to overlap each other and the curler can be easily wrapped around the living wrist.

[0021] There is provided a blood pressure measuring device according to the above aspect of the cuff structure, further comprising a guide portion that guides the other end of the curler, overlapping the one end, to the outside of the one end.

[0022] According to this aspect, the guide portion can guide one end of the curler to the other end of the curler, making it easy to overlap the ends of the curler.

[0023] There is provided a blood pressure measuring device of the cuff structure of the above aspect, wherein the guide portion is a protrusion provided at the one end or the other end of the curler and moves the other end outward.

[0024] According to this aspect, by forming the guide portion by the protrusion, it becomes easier to guide the curler from one end to the other end.

[0025] There is provided a blood pressure measuring device in the cuff structure of the above aspect, wherein the guide portion is a sheet member that covers an end of the fluid bag and is provided on an inner surface of the band extending from the curler.

[0026] According to this aspect, by covering the fluid bag and the other end of the curler with the sheet member, it is possible to prevent one end of the curler from interfering with the fluid bag and the curler in the circumferential direction.

[0027] A blood pressure measuring device is provided in which the cuff structure of one embodiment described above is formed by a fixed part that is fixed to the device main body, which is formed of a low hardness material and a high hardness material inserted into the low hardness material and has a higher hardness than the low hardness material, and the outer surface of the fluid bag is fixed integrally to the fixed part and the band.

[0028] According to this aspect, even if the curler is made of a material with a relatively low hardness, when the fluid bag is pressed toward the living body by the band and then fastened by the hook-and-loop fastener, the curler can be bent and deformed to conform to the shape of the living body. In addition, the fluid bag is configured such that the outer peripheral surface is covered by the band. This makes it possible to suppress the fluid bag from deforming radially outward when the fluid bag expands. Therefore, the fluid bag easily deforms to conform to the shape of the living body, and the fluid bag can be efficiently pressed toward the living body by suppressing the fluid bag from deforming radially outward during blood pressure measurement.

[0029] In addition, since the curler is formed by inserting a high-hardness material that is harder than the material forming the curler into the fixed portion that is fixed to the device body, the strength of the fixed portion that is attached to the device body can be improved.

[0030] There is provided a blood pressure measuring device according to the above-mentioned one aspect of the cuff structure, comprising a sensor provided on an inner surface of one end of the curler and spaced apart from the fluid bag in the longitudinal direction of the curler, the sensor detecting information of a living body.

[0031] According to this aspect, by providing the sensor for detecting information about the living body on the curler, it becomes possible to bring the sensor into contact with the living body, and to detect information about the living body other than blood pressure. Effect of the Invention

[0032] According to the present invention, it is possible to provide a blood pressure measuring device that can prevent displacement of the curler and the fluid bag, has a good appearance, and is highly accurate. [Brief description of the drawings]

The housing 11 also houses, for example, a fluid circuit 24 and a board 25. Here, the fluid circuit 24 may include, for example, a tube or a flow path plate that forms a flow path of the fluid supplied from the pump 14 to the cuff structure 4, components such as a fluid resistor that controls the supply amount and pressure of the fluid supplied to the cuff structure 4, and a check valve that controls the flow direction of the fluid. In addition, the board 25 is mounted with, for example, the acceleration sensor 15, the communication unit 19, the circuit configuration of the charging circuit unit 21, the memory 22, and the processor 23.

[0040] The housing 11 includes, for example, an outer case 31 , a windshield 32 that covers an upper opening of the outer case 31 , and a back cover 33 that covers the lower part of the outer case 31 .

[0041] The outer case 31 is formed, for example, in a cylindrical shape, a rectangular tube shape, a polygonal tube shape, or the like. In this embodiment, an example in which the outer case 31 is formed in a rectangular tube shape is shown. The outer case 31 has a loop portion 31a provided on one surface of the outer circumferential surface. The loop portion 31a is a rectangular annular member having an opening that is long in one direction through which the band 5 can be inserted in order to pass the band 5 through and fold the band 5 back. The loop portion 31a is formed integrally with the outer surface of the outer case 31. The windshield 32 is a glass plate having a shape similar to the outer peripheral edge shape of the outer case 31, which is rectangular in this embodiment. Note that the windshield 32 is not limited to a glass plate as long as it is a transparent or translucent material. The back cover 33 closes the bottom of the outer case 31. Note that the housing 11 may be configured not to have the back cover 33, and the bottom of the outer case 31 may be closed by a curler 51 (described later) of the cuff structure 4 fixed to the housing 11.

[0042] The display unit 12 is disposed 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 electroluminescence display. The display unit 12 displays various information including date and time, blood pressure values ​​such as systolic blood pressure and diastolic 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, for example, in the same shape as the windshield 32 in a planar view.

[0043] 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 commands operated by the user into electrical signals. The sensor and the touch panel 43 are electrically connected to the processor 23 and output the electrical signals to the processor 23.

[0044] The pump 14 is, for example, a piezoelectric pump. The pump 14 compresses, for example, air as a fluid, and supplies the compressed air to a pressure cuff 52 and a sensing cuff 54 (described later) of the cuff structure 4 through a fluid circuit. The pump 14 is electrically connected to the processor 23.

[0045] The acceleration sensor 15 is, for example, a three-axis acceleration sensor. The acceleration sensor 15 measures, for example, acceleration and outputs an analog signal. The acceleration sensor 15 is connected to the processor 23 via, for example, an A / D conversion circuit.

[0046] The valve 16 is, for example, an on-off valve. The valve 16 opens and closes a fluid circuit connecting the pump 14 and the cuff structure 4 and / or a fluid circuit connecting the cuff structure 4 and a standby. The valve 16 is electrically connected to the processor 23. For example, the valve 16 is opened and closed under the control of the processor 23.

[0047] As a specific example, the valve 16 is a safety valve that releases air supplied to a pressure cuff 52 and a sensing cuff 54 (described later) of the cuff structure 4 to the atmosphere. The valve 16 is switched to a closed state by being controlled by the processor 23 when supplying air to the pressure cuff 52 and the sensing cuff 54 during blood pressure measurement, for example. The valve 16 is also switched from a closed state to an open state by being controlled by the processor 23 when exhausting the pressure cuff 52 and the sensing cuff 54. The valve 16 may be formed so that the opening degree can be adjusted. The valve 16 may be provided on the fluid circuit 24, or may be provided integrally inside the housing of the pump 14.

[0048] The pressure sensor 17 is provided in, for example, the fluid circuit 24. The pressure sensor 17 detects the pressure of the pressure 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 via, for example, an A / D conversion circuit, converts the detected pressure into an electrical signal, and outputs it to the processor 23.

[0049] The battery 18 is, for example, a secondary battery such as a rechargeable lithium ion battery. 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, as well as to the display unit 12, the operation unit 13, the pump 14, the acceleration sensor 15, the valve 16, the pressure sensor 17, and the communication unit 19 via the processor 23.

[0050] The communication unit 19 is configured to be capable of transmitting and receiving information wirelessly and / or wired to and from an external device. The communication unit 19 is, for example, a wireless communication module that complies with a wireless communication standard. The communication unit 19 transmits, for example, information controlled by the processor 23 and information such as measured blood pressure values ​​and pulse rates to the external device, and also receives a program for software update from the external device and sends it to the control unit. In this embodiment, the external device is, for example, an external terminal such as a smartphone, a tablet terminal, a personal computer, or a smart watch.

[0051] In this embodiment, the communication unit 19 and the external terminal may be directly connected or may be connected via a network. The communication unit 19 and the external terminal may be connected via a mobile communication network such as 4G or 5G, or a wireless communication line such as Wimax or Wi-Fi (registered trademark). The communication unit 19 and the external device may be connected by a wireless communication means such as BLE (Bluetooth (registered trademark) Low Energy), NFC (Near Field Communication), or infrared communication. The communication unit 19 may have, in addition to a wireless communication module, a general-purpose connector such as a micro USB (Universal Serial Bus) or a dedicated connector for the blood pressure measurement device 1, and may be connected to the external terminal directly or via a wired communication line such as a LAN (Local Area Network) connection by various cables such as a USB cable. For this reason, the communication unit 19 may be configured to include a plurality of communication means such as a wireless antenna and a micro USB connector. The connector for wired communication may be a dedicated connector for the blood pressure measurement device 1.

[0052] The biosensor 20 is a sensor formed to be able to detect bioinformation by contacting or facing the wrist 300. The biosensor 20 converts the detected bioinformation into an electric signal and outputs it to the processor 23. The biosensor 20 may be, for example, a sensor that measures a physical quantity such as a heart rate or a body temperature, or may be a sensor that measures a chemical value such as a blood glucose level or a blood oxygen concentration. For example, the biosensor 20 is provided on the back cover 33 of the housing 11 and / or on a curler 51 (to be described later) of the cuff structure 4. In the present embodiment, the biosensor 20 is provided on the curler 51. Note that the blood pressure measurement device 1 may not include the biosensor 20. The biosensor 20 is connected to the substrate 25 via, for example, a pogo pin 26 and an FPC (Flexible Printed Circuits) 27. Here, the pogo pin is, for example, a spring probe or a contact probe.

[0053] The charging circuit unit 21 includes, for example, an antenna unit 211, a power receiving unit 212, and a charging unit 213. The charging circuit unit 21 charges the battery 18 by wireless power supply. For example, the charging circuit unit 21 receives transmission power transmitted from the antenna unit 103 of the power transmitting device 100 provided externally, and charges the battery 18.

[0054] The antenna unit 211 receives the transmitted power from the antenna unit of the power transmitting device. The antenna unit 211 is, for example, a power receiving coil serving as a power receiving resonant 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 flat shape. The antenna unit 211 is disposed, for example, within the housing 11. As a specific example, the antenna unit 211 is disposed adjacent to the display unit 12 on the opposite side of the windshield 32 of the display unit 12 within the housing 11. The antenna unit 211 includes, for example, a resonant capacitor, and constitutes a power receiving resonant circuit.

[0055] Power receiving unit 212 rectifies the power received by antenna unit 211 and supplies it to charging unit 213. As a specific example, power receiving unit 212 rectifies the received power supplied from antenna unit 211 and converts it from AC to DC. For example, power receiving unit 212 includes a rectifier circuit and a control circuit, controls the operation of the rectifier circuit by the control circuit, and outputs the rectified DC power to charging unit 213.

[0056] The charging unit 213 supplies the power supplied from the power receiving unit 212 to the battery 18 as charging power. 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 power to the battery 18. In addition, for example, the charging unit 213 may have a circuit that outputs the charging state of the battery 18 to the power receiving unit 212 and / or the processor 23.

[0057] The memory 22 includes, for example, a RAM (Random Access Memory) and a ROM (Read Only Memory). The memory 22 stores various data. For example, the memory 22 pre-stores, in a changeable manner, various program data such as programs and applications for controlling the entire blood pressure measuring device 1 and the pump 14, setting data for setting various functions of the blood pressure measuring device 1, calculation data for calculating a blood pressure value and a pulse rate from the pressure measured by the pressure sensor 17, and the like.

[0058] The processor 23 controls the operation of the entire blood pressure measuring device 1 and the operation of the pump 14 and the valve 16 based on the programs stored in the memory 22, and executes predetermined operations (functions). The processor 23 also executes predetermined calculations, analyses, processing, etc. according to the loaded programs. The processor 23 is a calculation device such as a CPU. The processor 23 may include, for example, a main CPU and a sub-CPU. The processor 23 also displays the status and results of the various executed operations and the calculations, analyses, processing, etc. on the display unit 12 by a program or an application.

[0059] The cuff structure 4 includes, for example, a curler 51, a pressure cuff 52, a back plate 53, and a sensing cuff 54. The cuff structure 4 is configured by laminating the curler 51, the pressure cuff 52, the back plate 53, and the sensing cuff 54.

[0060] Specific examples of cuff structure 4 will be described below with reference to Figures 1 to 3 and 5. As shown in Figures 1 to 3 and 5, cuff structure 4 includes curler 51, pressure cuff 52, back plate 53, and sensing cuff 54.

[0061] One end of curler 51 is fixed to the wrist side of housing 11, for example. Curler 51 is formed in a band shape that curves to follow the circumferential direction of wrist 300. Curler 51 is made of a resin material. Curler 51 is formed of a low-hardness material that is flexible and has shape retention. Here, flexibility means that curler 51 deforms in the radial direction when an external force of band 5 is applied to curler 51. Shape retention means that curler 51 can maintain a preformed shape when no external force is applied. That is, curler 51 is formed of a resin material that does not undergo compressive deformation or does not omit compressive deformation, but has a hardness that allows elastic deformation such as bending deformation that changes the shape, particularly the curvature of the curved portion. Thus, curler 51 is formed to be elastically deformable so that it bends and deforms when an external force is applied to it, and the internal space in which wrist 300 is placed becomes larger or smaller according to the shape of the wrist on which it is worn. For example, curler 51 is formed from a thermoplastic polyurethane resin (hereinafter, abbreviated as TPU).

[0062] For example, curler 51 has groove 51a formed on its outer circumferential surface in which band 5 is disposed and fixed. In other words, curler 51 has a pair of walls 51b along the longitudinal direction at a pair of edges along the longitudinal direction of the outer circumferential surface, and groove 51a in which band 5 is disposed and fixed is formed between this pair of walls 51b. For example, groove 51a is formed along the outer circumferential surface of curler 51 from one end to the other end of curler 51.

[0063] Moreover, curler 51 is formed such that one side from the portion fixed to housing 11 is longer than the other side. Both ends of curler 51 are formed to a length and shape that are located on one side of wrist 300 between the palm side and the back side of wrist 300 when curler 51 is worn on either wrist 300 with the longest circumference or wrist 300 with the shortest circumference among the users who are expected to wear curler 51. Curler 51 is formed, for example, in a shape in which one end overlaps the other end. Curler 51 is inclined such that, for example, the end face of the end located radially inward when both ends overlap faces the overlapping end side. Curler 51 may be formed in a shape that is curved so that the entire longitudinal direction follows the shape of wrist 300, or a part of it may be formed in a flat plate shape.

[0064] As a specific example, curler 51 is fixed to, for example, outer case 31 or back cover 33 of housing 11. Curler 51 also includes fixed part 61 formed in a flat plate shape and fixed to back cover 33, a first curved part 62 provided at one end of fixed part 61 and curved with a predetermined radius of curvature, and a second curved part 63 provided at the other end of fixed part 61 and curved with a predetermined radius of curvature.

[0065] A reinforcing material made of a high-strength material such as PC (polycarbonate) is inserted into fixed portion 61 by, for example, insert molding. The inserted reinforcing material is a material that forms curler 51, which in this embodiment is a material with a higher hardness than TPU. Fixed portion 61 also has holes formed therein in which, for example, fastening members such as screws for fixing curler 51 to housing 11, connection portions 73, 83, valves provided in fluid circuit 24, etc. are disposed.

[0066] The first curved portion 62 is formed to have a length from the fixed portion 61 to one side of the wrist 300. In addition, for example, a biosensor 20 is provided on the inner surface on the end side of the first curved portion 62. The second curved portion 63 is formed to have a length from the fixed portion 61 to the other side of the wrist 300, beyond the palm side of the wrist 300, to one side of the wrist 300 where the end of the first curved portion 62 is located.

[0067] 2, in a state before an external force is applied to curler 51, the end of second curved portion 63 may be located radially outward from the end of first curved portion 62 and spaced apart in the circumferential direction, so that the ends of first curved portion 62 and second curved portion 63 are spaced apart. As a specific example, second curved portion 63 may be formed in a straight shape in the entire region or in part from the palm side to the end side of second curved portion 63, or may be formed in a curved shape with a single radius of curvature larger than the radius of curvature of the end side of first curved portion 62 or a curved shape with multiple different radii of curvature, or may be formed in a combination of these straight shapes and curved shapes.

[0068] Furthermore, when curler 51 is fastened to wrist 300 by band 5, for example, one of the end of first curved portion 62 and the end of second curved portion 63 is formed to be able to overlap and be positioned radially outward from the other. As a specific example, as shown in Figs. 2 and 3, the end of second curved portion 63 is positioned radially outward from the end of first curved portion 62, and is formed to be able to overlap the outer surface side of first curved portion 62 when curler 51 is fastened to wrist 300 by band 5. In other words, the end of second curved portion 63 is formed to be able to overlap the end of first curved portion 62. For example, first curved portion 62 is formed such that the inner circumferential surface side is longer than the outer circumferential surface side, so that the end face is inclined with respect to the longitudinal direction of first curved portion 62.

[0069] For example, the lengths of the first curved portion 62 and the second curved portion 63 may be configured so that the first curved portion 62 and the second curved portion 63 overlap on all wrists 300 on which the blood pressure measuring device 1 is expected to be worn. Also, for example, the first curved portion 62 and the second curved portion 63 may be configured so that the first curved portion 62 and the second curved portion 63 overlap when the blood pressure measuring device 1 is worn on a wrist 300 having a specific circumference, for example, on a wrist 300 having a circumference ranging from the median circumference to the shortest circumference among the wrists 300 on which the blood pressure measuring device 1 is expected to be worn.

[0070] Furthermore, a sensor attachment portion on which the biosensor 20 is provided is formed on the inner surface of the first curved portion 62 or the second curved portion 63 which is located radially inward when they overlap. In this embodiment, the sensor attachment portion is formed in the first curved portion 62, and the biosensor 20 is attached to the inner surface on the tip side of the first curved portion 62. The sensor attachment portion is provided spaced apart in the circumferential direction of the curler 51 from the air bags 71, 81 of the pressing cuff 52 and the sensing cuff 54 which are fixed to the inner circumferential surface of the curler 51.

[0071] Furthermore, the lengths of the first curved portion 62 and the second curved portion 63 are such that, regardless of the circumference of the wrist 300, the second curved portion 63 faces the area of ​​the wrist 300 where the two arteries 311, 312 are located, the second curved portion 63 is disposed on a part of the side of the wrist 300, and the end of the first curved portion 62 and the end of the second curved portion 63 are spaced apart. Here, the two arteries 311, 312 are the radial artery 311 and the ulnar artery 312.

[0072] Curled elastic member 51 has the greatest curvature at the boundary (ridge) between fixed portion 61 and first curved portion 62 and at the boundary (ridge) between fixed portion 61 and second curved portion 63, for example.

[0073] Such curler 51 is formed, for example, by insert molding into a rectangular flat plate, and then band 5 is bonded to groove 51a, and then the curler is formed into a predetermined curved shape using a molding die.

[0074] The pressure cuff 52 is fixed to the inner circumferential surface of the curler 51 by double-sided tape, adhesive, heat welding, or the like. The pressure cuff 52 is provided at least in the region of the second curved portion 63 where the artery of the wrist 300 is present. As a specific example, the pressure cuff 52 is provided in a longitudinal region of the curler 51 from the fixed portion 61 side of the first curved portion 62, including the ridges of the fixed portion 61 and the first curved portion 62, to the end side of the second curved portion 63. The pressure cuff 52 fits along the inner surface of the curler 51.

[0075] The pressure cuff 52 is fluidly connected to the pump 14 via the fluid circuit 24. One main surface of the pressure cuff 52 is fixed to the inner surface of the curler 51. When the pressure cuff 52 inflates, it presses against the back side of the wrist 300 and presses the back plate 53 and the sensing cuff 54 towards the wrist 300.

[0076] The pressure cuff 52 includes, for example, one or more air bags 71, and a connection part 73 such as a nipple that is provided on the air bag 71 and connected to the fluid circuit 24. Here, the air bag 71 is a bag-like structure, and in this embodiment, the blood pressure measuring device 1 is configured to use air by the pump 14, so an air bag will be used for the description, but when a fluid other than air is used, the bag-like structure may be a fluid bag that is inflated by the fluid. The air bag 71 is formed into a rectangular bag shape that is long in one direction.

[0077] Air bag 71 is formed into a bag shape by heat welding a plurality of sheet members. For example, when compression cuff 52 has a configuration including a plurality of air bags 71, the plurality of air bags 71 are stacked and integrally formed by welding or the like, and are fluidly continuous. The sheet member forming air bag 71 is formed of, for example, a thermoplastic elastomer. Here, the thermoplastic elastomer is, for example, TPU.

[0078] The back plate 53 is fixed to the surface of the pressure cuff 52 on the wrist 300 side by double-sided tape, adhesive, or the like. The back plate 53 is made 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. Note that the back plate 53 may be configured to be divided, that is, formed by arranging a plurality of rectangular pieces in one direction. The back plate 53 has shape-following properties.

[0079] Here, shape conformability refers to the ability of the back plate 53 to deform so as to follow the shape of the contacted portion of the wrist 300 on which it is placed, the contacted portion of the wrist 300 refers to the area of ​​the wrist 300 that comes into contact with the back plate 53, and contact here includes both direct contact with the back plate 53 and indirect contact via the sensing cuff 54 of the back plate 53.

[0080] The sensing cuff 54 is fixed to the main surface of the back plate 53 on the wrist side. The sensing cuff 54 comes into direct contact with the area of ​​the wrist 300 where the arteries 311, 312 are present, or indirectly through a cover or the like. The sensing cuff 54 is formed in a rectangular shape that is long in one direction. The sensing cuff 54 may be configured to come into contact with the area of ​​the wrist 300 where one of the arteries 311, 312 is present. The sensing cuff 54 is smaller than the pressing cuff 52 in the longitudinal direction. The sensing cuff 54 is the same as or smaller than the pressing cuff 52 in the transverse direction. The sensing cuff 54 has the same shape as the back plate 53 or is smaller than the back plate 53 in the longitudinal direction and width direction of the back plate 53. The sensing cuff 54 inflates to compress the area of ​​the wrist where the arteries are present on the palm side. The sensing cuff 54 is pressed against the living body side via the back plate 53 by the inflated pressure cuff 52 .

[0081] As a specific example, the sensing cuff 54 includes an air bag 81, a flow path body 82 fluidly connected to the air bag 81, and a connection portion 83 provided on the flow path body 82. The air bag 81 and the flow path body 82 are formed into a bag shape by thermal welding or the like of a plurality of sheet members. The sheet members forming the air bag 81 and the flow path body 82 are formed of, for example, a thermoplastic elastomer. Here, the thermoplastic elastomer is, for example, TPU.

[0082] Here, air bag 81 is a bag-like structure, and in this embodiment, an air bag will be used for explanation since blood pressure measuring device 1 is configured to use air by pump 14, but when a fluid other than air is used, the bag-like structure may be a fluid bag that expands with the fluid, etc. Air bag 81 is configured in a rectangular shape that is long in one direction.

[0083] The flow path body 82 is provided, for example, integrally with a part of one edge in the longitudinal direction of the air bag 81. The flow path body 82 is provided at an end of the air bag 81 close to the device body 3. The flow path body 82 is formed in a shape that is elongated in one direction with a width smaller than the width of the air bag 81 in the short direction. A connection part 83 is provided integrally with the tip of the flow path body 82. The flow path body 82 is connected to the fluid circuit 24 via the connection part 83, and forms a flow path between the fluid circuit 24 and the air bag 81. The connection part 83 is, for example, a nipple.

[0084] The band 5 is formed in a belt shape. The band 5 has, for example, a pair of hook-and-loop fasteners 5a, one of which has a hook and the other of which has a loop, and these fasteners engage with each other to fix the band 5, the end of which is inserted into the loop portion 31a.

[0085] Band 5 is formed integrally with curler 51 or pressure cuff 52, and curler 51 or pressure cuff 52 is fastened to wrist 300 to bring pressure cuff 52 and sensing cuff 54 into close contact with wrist 300. In other words, band 5 is formed so that curler 51 can be tightened to deform it toward wrist 300, thereby pressing pressure cuff 52 and sensing cuff 54 toward wrist 300.

[0086] In this embodiment, band 5 is welded or attached to groove 51a of curler 51 and is formed integrally with curler 51. Band 5 extends from one end of first curved portion 62 or second curved portion 63 of curler 51, which is located on the outside when they overlap. In this embodiment, band 5 extends from the end of second curved portion 63, and loop portion 31a is provided on the outer surface of outer case 31 on the side where first curved portion 62 is provided. Band 5 is inserted into loop portion 31a provided on outer case 31 when wrist 300 having the maximum circumference expected to be worn is fastened, and a foldable length extends from second curved portion 63.

[0087] Band 5 has, for example, a pair of hook-and-loop fasteners 5a provided on one main surface of a fabric material, and grooves 51a of curler 51 attached to the other main surface. The fabric material of band 5 is made of a material that is less stretchable than curler 51. Band 5 reinforces curler 51 by attaching the fabric material to curler 51. In other words, band 5 is made of a material that is less stretchable than curler 51, and by attaching the fabric material to curler 51, it suppresses deformation of curler 51 outward in the radial direction.

[0088] Next, an example of the power transmitting device 100 that transmits power to the charging circuit section 21 of the device main body 3 will be described. 4, the power transmitting device 100 includes a power source 101, a power transmitting unit 102, and an antenna unit 103. The power source 101 is, for example, an AC adapter connected to a commercial power source, etc. The power source 101 converts AC power input from the commercial power source into DC power, and supplies the DC power to the power transmitting unit 102.

[0089] The power transmitting unit 102 generates AC power as transmission power from the DC power supplied from the power source 101, and supplies the AC power to the antenna unit 103. The power transmitting unit 102 generates AC power having a frequency that is the same as or approximately the same as the resonant frequency of a power transmitting resonant circuit formed by the antenna unit 103, for example.

[0090] The antenna unit 103 is, for example, a power transmitting coil serving as a power transmitting resonant circuit. The power transmitting 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 resonance capacitor, and constitutes a power transmitting resonant circuit.

[0091] In blood pressure measuring device 1 configured in this manner, band 5 is provided integrally with the outer peripheral surface of curler 51, and as a result, there is no misalignment between band 5 and curler 51, i.e., no misalignment between band 5 and pressure cuff 52 provided on the inner peripheral surface of curler 51. This allows pressure cuff 52 and sensing cuff 54 to be stably pressed against the wrist, making it possible to stabilize the accuracy of blood pressure measurement and prevent deterioration of air bladders 71, 81.

[0092] Moreover, since band 5 is provided on the outer peripheral surface of curler 51, sagging or wrinkles do not occur in band 5, and high appearance can be achieved.

[0093] Furthermore, curler 51 is formed to be longer than the longitudinal length of pressure cuff 52, and band 5 is attached integrally to the outer circumferential surface of curler 51 and extends from an end of second curved portion 63 of curler 51. Therefore, curler 51 is elastically deformed to conform to the shape of wrist 300, and band 5 can be fixed by fastening curler 51 to wrist 300 with a pair of hook-and-loop fasteners 5a.

[0094] Moreover, curler 51 is formed of a low hardness material such as TPU, and band 5 is formed of a material less stretchable than curler 51. As a result, when band 5 presses pressure cuff 52 and sensing cuff 54 toward wrist 300 and fastens with hook-and-loop fastener 5a, curler 51 can be bent and deformed to conform to wrist 300. In addition, curler 51 is configured such that the outer circumferential surface is covered by band 5, the cloth material of which is less stretchable than curler 51. As a result, curler 51 can be prevented from deforming radially outward when pressure cuff 52 and sensing cuff 54 are inflated. Therefore, curler 51 easily elastically deforms to conform to the shape of wrist 300, and can efficiently press sensing cuff 54 toward wrist 300 during blood pressure measurement.

[0095] Moreover, curler 51 is formed by inserting fixed portion 61, which is fixed to device body 3, with a high hardness material having a higher hardness than the low hardness material, TPU, that forms curler 51. This improves the strength of fixed portion 61 attached to device body 3, and therefore curler 51 can be prevented from being damaged even if device body 3 is fixed with screws or the like.

[0096] Furthermore, device main body 3 has loop portion 31a on housing 11, and band 5 is configured to be folded back at loop portion 31a and then fixed with a pair of hook-and-loop fasteners 5a. Therefore, band 5 can easily fasten curler 51, and pressure cuff 52 and sensing cuff 54 can be stably attached to wrist 300.

[0097] Furthermore, when curler 51 is attached to a living body having at least the smallest circumferential length of wrist 300 on which it is intended to be attached, one end of curler 51 overlaps the other, so that sensing cuff 54 can be brought into contact with the area in which arteries 311, 312 are located regardless of whether curler 51 is attached to wrist 300 having a different circumferential length. That is, in blood pressure measuring device 1, both ends of curler 51 abut in the circumferential direction, preventing a gap from occurring between wrist 300 and sensing cuff 54, and allowing pressure cuff 52 and sensing cuff 54 to fit closely to wrist 300.

[0098] Moreover, the first curved portion 62, which is one end of the curler 51, has a smaller radius of curvature than the second curved portion 63 that overlaps the first curved portion 62. As a result, before fastening the band 5, the second curved portion 63 of the curler 51 is located radially outward of the first curved portion 62, and therefore, when fastened by the band 5, the second curved portion 63 can be disposed outside the first curved portion 62. Furthermore, when curler 51 is fastened by the band 5, the trajectory of movement of the second curved portion 63 can be wound up along a trajectory that covers the first curved portion 62, and the second curved portion 63 can be easily overlapped with the first curved portion 62. In this way, in the blood pressure measurement device 1, when curler 51 is fastened by the band 5, the ends are easily overlapped and curler 51 is easily wrapped around the wrist 300.

[0099] Furthermore, blood pressure measuring device 1 is configured such that band 5 is attached integrally to the outer peripheral surface of groove 51a of curler 51, so that the edge portion in the width direction of band 5 faces a pair of walls 51b of curler 51. As a result, the edge portion in the width direction of band 5 is covered by the pair of walls 51b, and therefore band 5 can be prevented from peeling off from the outer peripheral surface of curler 51 due to an external force.

[0100] In the blood pressure measuring device 1 configured in this manner, the band 5 and curler 51 are integrally formed, so that the device has a good appearance, and since misalignment between the band 5 and curler 51 and the air bags 71, 81 can be prevented, highly accurate blood pressure measurement is possible.

[0101] The present invention is not limited to the above-mentioned embodiment. For example, in the above-mentioned example, the band 5 is fixed to the outer circumferential surface of the curler 51. However, the band 5 may have a portion of the curler 51, for example, a portion not exposed to the outside, for example, a portion located at the fixed portion 61, that is not fixed, or may have a notch in a direction perpendicular to the longitudinal direction. The curler 51 is formed in a strip shape extending in one direction, to which the band 5 is fixed, and is then shaped into a curved shape to follow the shape of the wrist 300. At this time, the curler 51 has an inner and outer periphery difference due to its thickness, and at this time, there is a risk that the band 5 fixed to the curler 51 may bend. However, if a portion of the band 5 is not fixed to the curler 51 or has a notch, even if wrinkles or the like occur in that portion due to the inner and outer periphery difference of the band 5, the wrinkles will not be exposed to the outside, and the appearance can be prevented from being impaired.

[0102] In addition, for example, the blood pressure measuring device 1 described above has a configuration in which one of the first curved portion 62 at one end side of curler 51 and the second curved portion 63 at the other end side overlaps the other. Here, curler 51 may have a configuration including guide portion 55 that guides first curved portion 62 and second curved portion 63 to move outward when one of them overlaps the other.

[0103] For example, when the second curved portion 63 moves outward from the first curved portion 62, if the pressing cuff 52 and the sensing cuff 64 come into contact with the end of the first curved portion 62, there is a risk that the movement of the second curved portion 63 will be restricted. For this reason, the curler 51 has a guide portion 55 that guides the second curved portion 63 from moving outward from the first curved portion 62, so that the second curved portion 63 rides up the end of the first curved portion 62 and becomes more likely to overlap with the first curved portion 62.

[0104] 6, such a guide portion 55 is a protrusion that protrudes radially inward from the end of the second curved portion 63. For example, the guide portion 55 is formed in a curved surface shape that is inclined with respect to the direction of abutment with the end of the first curved portion 62, or has an inclined tangent. When such a guide portion 55 abuts against the first curved portion 62, the inclined surface comes into contact with the tip of the first curved portion 62, and the second curved portion 63 moves in a direction intersecting the direction of abutment with the first curved portion 62, i.e., radially outward.

[0105] Moreover, such a guide portion 55 is preferably formed to be higher than the sum of the thicknesses of the pressure cuff 52, the back plate 53, and the sensing cuff 54, for example. That is, the tip of the guide portion 55 is preferably located radially inward from the inner circumferential surface of the curler 51 relative to the sensing cuff 54. As a result, the second curved portion 63 is located outward from the first curved portion 62, and the second curved portion 63 can overlap the first curved portion 62. Furthermore, the guide portion 55 can prevent the first curved portion 62 from contacting the pressure cuff 52, the back plate 53, and the sensing cuff 54. In this way, by providing the guide portion 55, the blood pressure measurement device 1 can more reliably cause the second curved portion 63 to overlap the first curved portion 62.

[0106] The guide portion 55 is not limited to the example shown in Fig. 6. For example, as shown in Fig. 7, the guide portion 55 may be a protrusion formed at the tip of the first curved portion 62 and having an inclined surface that is inclined with respect to the direction in which the first curved portion 62 and the second curved portion 63 come into contact with each other.

[0107] 8, guide portion 55 may be configured to cover ends of back plate 53, pressure cuff 52, and curler 51 using a sheet member that is continuous with air bag 81 of outermost sensing cuff 54 and band 5. For example, guide portion 55 is formed by forming a part of the sheet member that forms air bag 81 into a shape longer than the shape of air bag 81 and attaching it integrally to band 5. Alternatively, guide portion 55 is formed by attaching a rectangular sheet member separate from air bag 81 integrally to the outer surface of air bag 81 and band 5. With this configuration, guide portion 55 forms an inclined surface that is inclined with respect to the direction in which first curved portion 62 and second curved portion 63 come into contact with each other, and guides the movement of second curved portion 63.

[0108] In the above example, the blood pressure measuring device 1 has been described as having a loop portion 31a provided on the housing 11, and the band 5 is looped at the loop portion 31a, but is not limited thereto. For example, as shown in Fig. 9, the blood pressure measuring device 1 may have a configuration in which the hook-and-loop fastener 5a of the band 5 provided on the first curved portion 62 and the hook-and-loop fastener 5a of the band 5 extending from the second curved portion 63 are joined together without having the loop portion 31a.

[0109] In the above-described example, the blood pressure measurement device 1 has been described as an example in which the second curved portion 63 overlaps the outside of the first curved portion 62, but is not limited thereto. For example, as shown in Fig. 10, the first curved portion 62 may overlap the outside of the second curved portion 63. In such a configuration, the band 5 may extend from the end of the first curved portion 62, and the loop portion 31a may be provided on the outer surface of the outer case 31 of the housing 11 on the side from which the second curved portion 63 extends.

[0110] In the above example, curler 51 is longer than pressure cuff 52, and pressure cuff 52 is provided integrally with the inner circumferential surface of curler 51; however, the present invention is not limited to this. For example, curler 51 may have only fixed portion 61 attached to housing 11, as shown in Fig. 11, and pressure cuff 52 may be fixed to the inner circumferential surface of band 5 attached integrally to fixed portion 61. In such a configuration, band 5 may have a layer formed of, for example, TPU as a thermoplastic elastomer on the inner surface of the fabric material, and band 5 and pressure cuff 52 may be fixed integrally by heat welding.

[0111] That is, the present invention is not limited to the above embodiment, and can be modified in various ways in the implementation stage without departing from the gist of the invention. In addition, each embodiment may be implemented in appropriate combination as much as possible, and in that case, the combined effect can be obtained. Furthermore, the above embodiment includes inventions at various stages, and various inventions can be extracted by appropriate combinations of the multiple constituent elements disclosed. Note that the present invention is not limited to the above embodiment, and can be modified in various ways in the implementation stage without departing from the gist of the invention. In addition, each embodiment may be implemented in appropriate combination, and in that case, the combined effect can be obtained. Furthermore, the above embodiment includes various inventions, and various inventions can be extracted by combinations selected from the multiple constituent elements disclosed. For example, if some constituent elements are deleted from all the constituent elements shown in the embodiment, and the problem can be solved and an effect can be obtained, the configuration from which the constituent elements are deleted can be extracted as an invention.
