Description

Technical Field

[0001] This invention relates to a flow path plate unit and a blood pressure measuring device. Background Technology

[0002] In recent years, blood pressure measuring devices have been used not only in medical facilities but also in homes as tools for monitoring health status. These devices, for example, measure blood pressure by inflating and contracting a cuff wrapped around the upper arm or wrist, using a pressure sensor to detect the pressure in the cuff, thereby detecting vibrations in the arterial walls.

[0003] As such a blood pressure measuring device, there is a known technique in which a partition is provided between a base plate on one side of which a pump or the like is provided and a plate-shaped member disposed opposite to the other side of the base plate, and a flow path from the pump to the cuff is formed by a pattern formed on the partition plate (see Patent Document 1).

[0005] Patent Document 1: Japanese Patent Application Publication No. 2018-143557 Summary of the Invention

[0006] The problem the invention aims to solve

[0007] Recently, blood pressure measuring devices, as wearable devices worn on the wrist, have required miniaturization. However, in Patent Document 1, the separator is made of synthetic resin such as polyurethane, and in order to maintain the strength used to form the flow path pattern on the separator, the thickness dimension of the separator is increased. In addition, in order to reliably seal the flow path, it is necessary to bond the separator to the substrate and the plate-like member, which increases the size of the adhesive layer in the thickness direction.

[0008] As a result, because the thickness of the integral substrate, plate-like components and partitions increases, the housing used to house them also becomes larger.

[0009] Therefore, the object of the present invention is to provide a flow path plate unit and a blood pressure measuring device that can be miniaturized.

[0010] means for solving problems

[0011] According to one approach, a flow path unit is provided, comprising: a first flow path plate having at least one surface formed as a planar surface; a second flow path plate having a surface opposite to the planar surface of the first flow path plate formed as a planar surface; and an adhesive member having a notch formed in the shape of a flow path for bonding the first flow path plate and the second flow path plate.

[0012] According to this method, the flow path plate unit integrates the first flow path plate and the second flow path plate by means of an adhesive member, and the flow path is formed by the notch in the adhesive member. Therefore, it is not necessary to form a recess constituting the flow path on the first or second flow path plate, which reduces the thickness dimension of the flow path plate unit. As a result, miniaturization of the flow path plate unit can be achieved.

[0013] A flow path board unit according to the above method is provided, wherein the adhesive component is double-sided tape.

[0014] According to this method, by using double-sided tape as the adhesive component, it is easy to form notches, easy to bond the first and second flow path boards, and easy to manage the thickness. Therefore, by using double-sided tape as the adhesive component, the flow path board unit can easily form flow paths.

[0015] A flow path board unit according to the above-described manner is provided, wherein at least one of the first flow path board and the second flow path board is formed of a metallic material.

[0016] According to this method, for example, at least one of the first flow path plate and the second flow path plate can be formed by a metal plate, and the dimension in the thickness direction of the flow path plate unit can be reduced.

[0017] A flow path plate unit according to the above-described manner is provided, comprising: a plurality of nozzles disposed on a second flow path plate and connected to a cuff; and a fluid control unit disposed on at least one of the plurality of nozzles.

[0018] Here, the so-called cuff, which is wrapped around the upper arm or wrist of an organism when measuring blood pressure, includes a bag-like structure that expands by supplying fluid. The fluid includes liquids and air. When the fluid is air, the bag-like structure is, for example, an air bag that expands using air. The fluid control unit is, for example, a flow resistance element such as a throttle orifice or a check valve.

[0019] According to this method, by setting a fluid control unit on the nozzle connected to the sleeve, there is no need to set up a separate fluid control unit, so the flow path plate unit can be miniaturized.

[0021] According to this method, a third flow path plate is provided, which has flow paths. This increases the degree of freedom of the flow paths in the flow path plate unit, and because the third flow path plate does not have recesses, the flow path plate unit can be miniaturized. Furthermore, since a portion of the flow paths of the flow path plate unit is formed on the third flow path plate, the accuracy of the flow path shape can be improved.

[0022] A flow path plate unit according to the above-described manner is provided, wherein the flow path of the third flow path plate includes a fluid control unit in which fluid flows along the thickness direction of the third flow path plate.

Furthermore, by forming the fluid control section on the flow path of the third flow path plate, the fluid control section is formed from a portion of the third flow path plate. Therefore, the shape accuracy of the fluid control section can be improved.

[0024] A flow path board unit according to the above-described manner is provided, wherein the flow path of the third flow path board includes a fluid control unit in which fluid flows along the surface direction of the third flow path board.

Furthermore, by forming the fluid control section on the flow path of the third flow path plate, the fluid control section is formed from a portion of the third flow path plate. Therefore, the shape accuracy of the fluid control section can be improved.

[0026] According to one approach, a blood pressure measuring device is provided, comprising: a flow path unit having a first flow path plate, a second flow path plate, and an adhesive member, wherein at least one surface of the first flow path plate is planar, and a surface of the second flow path plate opposite to the planar surface of the first flow path plate is planar; the adhesive member has a notch formed in the shape of a flow path and adhesively bonds the first flow path plate and the second flow path plate; a pump connected to the flow path unit; a pressure sensor connected to the flow path unit; and a cuff connected to the flow path unit and fluidly connected to the pump and the pressure sensor via the flow path unit.

[0027] According to this method, the flow path plate unit integrates the first flow path plate and the second flow path plate by means of an adhesive member, and the flow path is formed by the notch in the adhesive member. Therefore, it is not necessary to form a recess constituting the flow path on the first or second flow path plate, which reduces the thickness dimension of the flow path plate unit. As a result, miniaturization of the flow path plate unit can be achieved.

[0028] A blood pressure measuring device according to the above method is provided, wherein the adhesive component is double-sided tape.

[0029] According to this method, by using double-sided tape as the adhesive component, it is easy to form notches, easy to bond the first and second flow path boards, and easy to manage the thickness. Therefore, by using the adhesive component as double-sided tape, the flow path board unit can easily form flow paths.

[0030] A blood pressure measuring device according to the above-mentioned method is provided, comprising: a plurality of nozzles disposed on a second flow path plate and connected to a cuff; and a fluid control unit disposed on at least one of the plurality of nozzles.

[0031] According to this method, by providing a fluid control unit on the nozzle connected to the cuff, there is no need to provide additional space for the fluid control unit, thus enabling miniaturization of the flow path plate unit. As a result, miniaturization of the blood pressure measuring device is possible.

[0032] A blood pressure measuring device according to the above-described manner is provided, wherein the adhesive member comprises: a third flow path plate having a flow path; a first adhesive member for bonding one main surface of the first flow path plate and one main surface of the third flow path plate; and a second adhesive member for bonding one main surface of the second flow path plate and another main surface of the third flow path plate.

[0033] According to this method, a third flow path plate is provided, which has flow paths. This increases the degree of freedom of the flow paths in the flow path plate unit, and because the third flow path plate does not have recesses, the flow path plate unit can be miniaturized. Furthermore, since a portion of the flow paths of the flow path plate unit is formed on the third flow path plate, the accuracy of the flow path shape can be improved.

[0051] [First Embodiment]

[0052] Below, using Figures 1-3An example of a blood pressure measuring device 1 according to the first embodiment of the present invention will be described.

[0053] Figure 1 This is a three-dimensional diagram showing the structure of the blood pressure measuring device 1. Figure 2 This is a block diagram showing the structure of the blood pressure measuring device 1. Figure 3 This is an exploded perspective view showing the structure of the pump 14, the on / off valve 16, the pressure sensor 17, and the flow path plate unit 22 of the blood pressure measuring device 1. Figure 4 This is a cross-sectional view showing the structure of the pump 14, pressure sensor 17, and flow path plate unit 22 of the blood pressure measuring device 1.

[0054] Blood pressure measuring device 1 is an electronic blood pressure measuring device worn on a living organism. In the example of this embodiment, blood pressure measuring device 1 is an electronic blood pressure measuring device that measures blood pressure based on arteries in the form of a wearable device worn on the wrist.

[0055] like Figures 1 to 4 As shown, the blood pressure measuring device 1 includes, for example, a device body 3, a belt 4, a collar 5, a cuff structure 7, and a fluid control unit 9.

[0056] The main body 3 of the device includes, for example, a housing 11, a display unit 12, an operation unit 13, a pump 14, an on / off valve 16, a pressure sensor 17, a power supply 18, a communication unit 19, a memory 20, a CPU 21, and a flow path board unit 22.

[0057] The housing 11, for example, houses the display unit 12, the operation unit 13, the pump 14, the on / off valve 16, the pressure sensor 17, the power supply 18, the communication unit 19, the memory 20, the CPU 21, and the flow board unit 22.

[0058] The housing 11 has, for example, an outer housing 31, a windshield 32 covering the upper opening of the outer housing 31, and a rear cover 35 covering the lower part of the outer housing 31.

[0059] The outer shell 31 is, for example, formed in a cylindrical shape. The outer shell 31 includes a pair of lugs 31a respectively disposed symmetrically in the circumferential direction on the outer peripheral surface, and spring rods 31b respectively disposed between the two pairs of lugs 31a. The windshield 32 is a circular glass plate.

[0060] The display unit 12 is located directly below the windshield 32. The display unit 12 is electrically connected to the CPU 21. The display unit 12 is, for example, a liquid crystal display or an organic electroluminescent display. The display unit 12 displays various information including date and time, blood pressure values ​​such as highest and lowest blood pressure, heart rate, and other measurement results.

[0061] The operation unit 13 is capable of receiving commands from the user. The operation unit 13 includes, for example, a plurality of buttons 41 mounted on the housing 11; sensors for detecting the operation of the buttons 41; and a touch panel 43 mounted on the display unit 12 or the windshield 32. When the user operates the operation unit 13, the operation unit 13 converts the commands into electrical signals. The sensors and the touch panel 43 are electrically connected to the CPU 21 and output electrical signals to the CPU 21.

[0062] Pump 14 is, for example, a piezoelectric pump. Pump 14, for example, compresses air and supplies compressed air to the sleeve structure 7 via the flow path unit 22. Pump 14 is electrically connected to CPU 21.

[0063] The on / off valve 16 is a safety valve that releases air supplied to the pressing cuff 71 to the atmosphere. The on / off valve 16 is connected, for example, to a branch flow path 22c1 of the first flow path 22c of the flow path unit 22 (described later), which connects the pump 14 and the on / off valve 16 to the pressing cuff 71. The on / off valve 16 is electrically connected to the CPU 21. For example, the CPU 21 controls the opening and closing of the on / off valve 16.

[0064] The on / off valve 16 is, for example, a quick-release valve that sets the opening degree of the on / off valve 16 or the opening area of ​​the first flow path 22c in a manner that minimizes fluid resistance, and is capable of rapid venting. When measuring blood pressure, air is supplied to the compression cuff 71 and the sensing cuff 73; in this case, the on / off valve 16 is switched to the closed state under the control of the CPU 21. Furthermore, when venting air from the compression cuff 71 and the sensing cuff 73, the on / off valve 16 is switched from the closed state to the open state under the control of the CPU 21. Additionally, the on / off valve 16 can also be configured to have an adjustable opening degree. Furthermore, the on / off valve 16 can also be integrally housed inside the frame of the pump 14.

[0065] Pressure sensor 17 is fluidly connected to flow path 22a. Pressure sensor 17 detects, for example, the pressure of sensing cuff 73 of cuff structure 7 via flow path 22a. Pressure sensor 17 is electrically connected to CPU 21, converts the detected pressure into an electrical signal, and outputs it to CPU 21.

[0066] The power supply 18 is, for example, a secondary battery such as a lithium-ion battery. The power supply 18 is electrically connected to the CPU 21. The power supply 18 supplies power to the CPU 21. The power supply 18 supplies driving power to each structure of the CPU 21, and supplies driving power to the display unit 12, the operation unit 13, the pump 14, the on / off valve 16, the pressure sensor 17, and the communication unit 19 via the CPU 21.

[0067] The communication unit 19 is capable of sending and receiving information with external devices wirelessly or via wired connection. For example, the communication unit 19 can send information controlled by the CPU 21, measured blood pressure values, and pulse information to external devices, or receive software update programs from external devices and send them to the control unit. In this embodiment, the external device is, for example, an external terminal such as a smartphone, tablet, personal computer, or smartwatch.

[0068] In this embodiment, the communication unit 19 can be directly connected to an external device or connected via a network. The communication unit 19 can also be connected to an external device via portable communication networks such as 4G and 5G, or wireless communication lines such as Wi-Fi MAX and Wi-Fi. Furthermore, the communication unit 19 can also be connected to an external device via wireless communication units such as Bluetooth, NFC (Near Field Communication), and infrared communication. Moreover, the communication unit 19 can also be connected to an external device via wired communication lines such as USB (Universal Serial Bus) or cable-based LAN (Local Area Network). Therefore, the communication unit 19 can include various communication units such as a wireless antenna and a micro USB connector.

[0069] The memory 20 includes, for example, RAM (Random Access Memory) and ROM (Read Only Memory). The memory 20 stores various types of data. For example, the memory 20 may be pre-stored program data for controlling the entire blood pressure measuring device 1 and pump 14, setting data for setting various functions of the blood pressure measuring device 1, and calculation data for calculating blood pressure values ​​or pulse based on the pressure measured by the pressure sensor 17.

[0070] The CPU 21 controls all operations of the blood pressure measuring device 1, as well as the pump 14 and the on / off valve 16, according to the program stored in the memory 20, and executes the prescribed actions (functions). In addition, the CPU 21 performs prescribed calculations, analysis, and processing according to the read program.

[0071] The flow path unit 22 is housed within the housing 11. The flow path unit 22 is fluidly connected to the pump 14, the on / off valve 16, the pressure sensor 17, and the cuffs 71 and 73 (described later) of the cuff structure 7. The flow path unit 22 has a flow path section 22a internally. Furthermore, the flow path section 22a is fluidly connected to the cuffs 71 and 73 and the atmosphere via the on / off valve 16.

[0072] The flow path unit 22 includes a first flow path 131, a second flow path 132, and an adhesive member 133 for bonding the first flow path 131 and the second flow path 132. The flow path section 22a is composed of the first flow path 131, the second flow path 132, and the adhesive member 133.

[0073] The surface of the first flow path plate 131 opposite to the second flow path plate 132 is planar. On the surface opposite to the surface of the first flow path plate 131 to the surface opposite to the second flow path plate 132, for example, a pump 14, a switching valve 16, and a pressure sensor 17 are fixed. The first flow path plate 131, for example, has holes fluidly connected to the pump 14, holes fluidly connected to the switching valve 16, and holes fluidly connected to the pressure sensor 17. The first flow path plate 131 is, for example, formed of a metallic material. The first flow path plate 131 is, for example, a metal plate. The thickness of the first flow path plate 131 is, for example, 0.4 mm.

[0074] The surface of the second flow path plate 132 opposite to the first flow path plate 131 is planar. The opposing surfaces of the second flow path plate 132 and the first flow path plate 131 have substantially the same shape. The second flow path plate 132 is, for example, made of a metallic material. The thickness of the second flow path plate 132 is, for example, 0.4 mm.

[0075] The adhesive member 133 adheres to the first flow path plate 131 and the second flow path plate 132. The adhesive member 133 has a notch 133a that, when adhering to the first flow path plate 131 and the second flow path plate 132, forms a flow path portion 22a together with the first flow path plate 131 and the second flow path plate 132. Specifically, the adhesive member 133 is formed such that its shape is approximately the same as the outer shape of the opposing surfaces of each flow path plate 131, 132, and the notch 133a is provided with a partially open shape corresponding to the flow path portion 22a.

[0076] The adhesive component 133 is, for example, double-sided tape. The adhesive component 133 is made of an airtight material. For example, the adhesive component 133 is a double-sided tape with a substrate made of an airtight material such as acrylic foam. Furthermore, the thickness of the adhesive component 133 is, for example, 0.2 mm.

[0077] Such an adhesive component 133 is aligned with the first flow path plate 131 and the second flow path plate 132, for example, by using alignment holes provided on the first flow path plate 131 and the second flow path plate 132. The adhesive component 133 is fixed to the first flow path plate 131 and the second flow path plate 132, for example, by manual operation by an operator.

[0078] Details of the flow path section 22a will be described later.

[0079] like Figure 1As shown, the belt 4 has: a first belt 61 disposed on a pair of lugs 31a and a spring bar 31b; and a second belt 62 disposed on another pair of lugs 31a and a spring bar 31b.

[0080] The first band 61, referred to as the so-called mother band, is band-shaped. The first band 61 has a buckle 61c at one end. The first band 61 is rotatably held on the outer housing 31. The buckle 61c has a rectangular frame-shaped body 61d and a buckle pin 61e rotatably mounted on the frame-shaped body 61d. The second band 62, referred to as the so-called sword tip, is band-shaped with a width that can be inserted into the frame-shaped body 61d. Furthermore, the second band 62 has multiple small holes 62a for inserting the buckle pins 61e.

[0081] With regard to this strap 4, the first strap 61 and the second strap 62 are integrally connected by inserting the second strap 62 into the frame 61d and inserting the buckle 61e into the small hole 62a, forming a ring along the circumference of the wrist together with the outer shell 31.

[0082] The collar 5 is made of resin material and is formed into a band that bends circumferentially along the wrist. For example, one end of the collar 5 is fixed to the wrist side of the device body 3.

[0083] Furthermore, the collar 5 possesses rigidity, which is a rigidity that exhibits flexibility and shape retention. Here, flexibility refers to the radial deformation of the collar 5 when an external force from the band 4 is applied. Shape retention refers to the ability of the collar 5 to maintain its pre-assigned shape when no external force is applied. A cuff structure 7 is disposed on the inner circumferential surface of the collar 5.

[0084] like Figure 1 As shown, the cuff structure 7 includes, for example, a pressing cuff 71, a back plate 72, and a sensing cuff 73. The cuff structure 7 is integrally formed by stacking the pressing cuff 71, the back plate 72, and the sensing cuff 73. The cuff structure 7 is fixed to the inner surface of the collar 5.

[0085] In this embodiment, the pressing cuff 71 of the cuff structure 7 is connected to the sensing cuff 73 via the fluid control unit 9, and the sensing cuff 73 is connected to the atmosphere via the fluid control unit 9.

[0086] The pressing cuff 71 is connected to the flow path plate unit 22. The pressing cuff 71 is fluidly connected to the pump 14 via the flow path plate unit 22. One main surface of the pressing cuff 71 is fixed to the inner surface of the collar 5. For example, the pressing cuff 71 is attached to the inner surface of the collar 5 by double-sided tape or adhesive. The pressing cuff 71 presses the back plate 72 and the sensing cuff 73 toward the organism by expansion.

[0087] Press the cuff 71, for example, with an air bag 81.

[0088] The air bag 81 is a bag-shaped structure. In this embodiment, the blood pressure measuring device 1 uses air via the pump 14, so an air bag is used for explanation. However, when using a fluid other than air, the bag-shaped structure may also be a fluid bag such as a liquid bag.

[0089] The back panel 72 is attached to the wrist side of the compression cuff 71 using double-sided tape or adhesive. The back panel 72 is formed of a resin material and is plate-shaped. For example, the back panel 72 is made of polypropylene and is plate-shaped with a thickness of approximately 1 mm. The back panel 72 has shape-following properties.

[0090] Here, shape following refers to the ability of the back plate 72 to deform in a manner that follows the shape of the contacted portion of the wrist, where the contacted portion of the wrist is the area that contacts the back plate 72, and this contact includes both direct and indirect contact.

[0091] A sensing cuff 73 is fixed to the main surface of the backplate 72 on the wrist side. The sensing cuff 73 directly contacts the area where the wrist artery is located. The sensing cuff 73 is formed in the same shape as or smaller than the backplate 72 in both the length and width directions. The sensing cuff 73 compresses the area where the wrist artery is located on the palm side by inflating. The sensing cuff 73 is pressed towards the body side via the backplate 72 by the inflated compression cuff 71.

[0092] As a specific example, the sensing cuff 73 has: an air bag 91; and a flow path 92.

[0093] Here, the air bag 91 is a bag-shaped structure. In this embodiment, the blood pressure measuring device 1 uses air via the pump 14, so an air bag is used for explanation. If a fluid other than air is used, the bag-shaped structure could be a liquid bag or the like.

[0094] The air bag 91 is a rectangle that extends in one direction. The air bag 91 is formed, for example, by combining two sheet members that extend in one direction, for example by heating the edges together.

[0095] The flow path body 92 is integrally provided on a portion of one edge of the air bag 91 along its length. The flow path body 92 is provided at the end of the proximity device body 3 of the air bag 91. Furthermore, the flow path body 92 is formed with a width smaller than the width dimension of the air bag 91, and is elongated in one direction. The flow path body 92 has, for example, a connecting portion at its top. The flow path body 92 is connected to the flow path portion 22a via the connecting portion, forming a flow path between the flow path portion 22a and the air bag 91.

[0096] The flow path 92 is constructed such that, with connecting portions arranged on two sheet members, a portion of the sheet member adjacent to the area constituting the air bag 91 of the sheet member is welded together in a frame shape that extends in one direction using heat, for example. Furthermore, the air bag 91 is configured such that a portion of the welded portion, which fixes the two sheet members into a rectangular frame shape by welding, is not welded and is continuous with the welded portion constituting the flow path 92, thereby fluidly communicating between the air bag 91 and the flow path 92.

[0097] The fluid control unit 9 controls, for example, the amount of air supplied to the cuffs 71 and 73. The fluid control unit 9 is, for example, a fluid resistance element such as a throttle orifice or a check valve. In this embodiment, the fluid control unit 9 includes, for example, multiple flow resistance elements. As a specific example, the fluid control unit 9 includes a first flow resistance element 121 and a second flow resistance element 122. The fluid control unit 9 controls the pressure ratio of the air in the two cuffs 71 and 73 to be constant by the flow resistance ratio of the first flow resistance element 121 and the second flow resistance element 122.

[0098] The fluid control unit 9 generates a pressure difference between the primary pressure of the first flow resistance member 121, the pressure between the first flow resistance member 121 and the second flow resistance member 122, and the secondary pressure of the second flow resistance member 122. The fluid control unit 9 uses these pressure differences to maintain a constant pressure ratio between the pressing cuff 71 on the primary side of the first flow resistance member 121 and the sensing cuff 73 between the first flow resistance member 121 and the second flow resistance member 122.

[0099] The first flow resistance element 121 connects the pressing cuff 71 to the sensing cuff 73. The flow path cross-sectional area of ​​the first flow resistance element 121 is, for example, smaller than the flow path cross-sectional areas of its primary and secondary sides. The first flow resistance element 121 is, for example, a throttling orifice. By narrowing the flow path from the pressing cuff 71 to the sensing cuff 73, the first flow resistance element 121 reduces the flow rate of air supplied to the secondary side of the first flow resistance element 121 relative to the flow rate of air supplied to the pressing cuff 71.

[0100] The second flow resistance element 122 connects the sensing sleeve 73 to the atmosphere. The flow path cross-sectional area of ​​the second flow resistance element 122 is, for example, smaller than the flow path cross-sectional area of ​​the primary side of the second flow resistance element 122. The second flow resistance element 122 is, for example, a throttling orifice.

[0101] The second flow resistance element 122 reduces the flow path from the first flow resistance element 121 to the atmosphere, thereby reducing the flow rate of air supplied to the secondary side (atmosphere) of the second flow resistance element 122 relative to the flow rate of air supplied to the sensing cuff 73.

[0102] The flow resistance ratio of the first flow resistance element 121 and the second flow resistance element 122 can be adjusted according to the characteristics of the cuffs 71 and 73 of the blood pressure measuring device 1.

[0103] Next, the flow path plate unit 22 will be described. Regarding the flow path plate unit 22, an example of the structure connected to the cuff structure 7 will be described. In the cuff structure 7, the pressing cuff 71 and the sensing cuff 73 are connected via the first flow resistance member 121; the sensing cuff 73 is connected to the atmosphere via the second flow resistance member 122.

[0104] The flow path section 22a of the flow path board unit 22 includes, for example, a first flow path 22c and a second flow path 22d.

[0105] The first flow path 22c fluidly connects the pump 14 and the on / off valve 16 to the press cuff 71. As a specific example, the first flow path 22c has a branch flow path 22c1 that branches off on the secondary side of the pump 14. The branch flow path 22c1 is connected to the on / off valve 16.

[0106] The second flow path 22d is the flow path connected to the pressure sensor 17.

[0107] As a specific example, a first hole 131a, a second hole 131b, and a third hole 131c are formed on the first flow path plate 131. Holes 131a, 131b, and 131c penetrate the first flow path plate 131.

[0108] The first hole 131a communicates with the nozzle of the pump 14. The first hole 131a forms part of the first flow path 22c. The first hole 131a is, for example, located on the central side of the first flow path plate 131. The second hole 131b is connected to the pressure sensor 17. The second hole 131b forms part of the second flow path 22d. The second hole 131b is, for example, located on the outer edge of the first flow path plate 131. The third hole 131c is connected to the on / off valve 16. The third hole 131c forms part of the branch flow path 22c1. The third hole 131c is, for example, located on the outer edge of the first flow path plate 131.

[0109] The second flow path plate 132, for example, has a flow path plate body 132a and a nozzle 132b.

[0110] The surface of the flow path plate body 132a opposite to the first flow path plate 131 is formed as a plane. The opposing surfaces of the flow path plate body 132a and the first flow path plate 131 are formed to have substantially the same shape. The flow path plate body 132a is, for example, a metal plate.

[0111] Nozzle 132b is disposed on the surface of flow path plate body 132a opposite to the adhesive member 133. Nozzle 132b is connected to sleeve structure 7. Nozzle 132b is formed of resin, for example. Nozzle 132b is integrally formed with flow path plate body 132a, for example, by insert molding.

[0112] As a specific example, nozzle 132b has a first nozzle 132b1 and a second nozzle 132b2. The first nozzle 132b1 is in communication with a first flow path 22c. The first nozzle 132b1 is connected to a pressing cuff 71. The second nozzle 132b2 is in communication with a second flow path 22d. The second nozzle 132b2 is connected to a sensing cuff 73. The second nozzle 132b2 is connected, for example, to a flow path body 92.

[0113] According to the blood pressure measuring device 1 configured in this way, the flow path plate unit 22 is integrally bonded to the first flow path plate 131 and the second flow path plate 132 by means of the adhesive member 133, thereby forming the flow path portion 22a by the notch 133a formed in the adhesive member 133.

[0114] Thus, by utilizing the notch 133a of the adhesive member 133 that bonds the first flow path plate 131 and the second flow path plate 132 to form a flow path, the thickness of the flow path plate unit 22 can be reduced. That is, since the flow path portion 22a is formed by utilizing the notch 133a of the adhesive member 133, it is not necessary to form a recess for the flow path portion 22a that extends in the direction along the mutually facing planes of the first flow path plate 131 and the second flow path plate 132. Therefore, for example, the flow path plate body 132a of the first flow path plate 131 and the second flow path plate 132 can be formed using a thin metal plate, and the dimension in the thickness direction of the flow path plate unit 22 can be reduced, thus enabling miniaturization of the blood pressure measuring device 1.

[0115] Furthermore, by making the adhesive member 133 a double-sided tape, the notch 133a can be easily formed by punching. In addition, by simply attaching the adhesive member 133 with the notch 133a to the first flow path plate 131 and the second flow path plate 132, a flow path plate unit 22 having a flow path portion 22a can be easily constructed.

[0116] In addition, since the adhesive members 133 have the same thickness, it is easy to manage the distance between the first flow path plate 131 and the second flow path plate 132, thus making it easy to manage the flow path.

[0117] As described above, according to this embodiment, by utilizing the notch 133a of the adhesive member 133 that bonds the first flow path plate 131 and the second flow path plate 132 to form a flow path, the flow path plate unit 22 and the blood pressure measuring device 1 can be miniaturized.

[0118] Furthermore, although the example of the above embodiment describes a structure in which the flow path plate unit 22 connects the pressing cuff 71 to the sensing cuff 73 and the sensing cuff 73 to the atmosphere, and connects the cuff structure 7 to the pump 14, it is not limited to this. The flow path plate unit 22 can modify the shape of the notch 133a of the adhesive member 133 according to the structure of the cuff structure 7, thereby appropriately modifying the flow path portion 22a. This example will be described using a first modified example and a second modified example.

[0119] use Figure 5 and Figure 6 The first variation will be explained. Figure 5 This is a block diagram showing the structure of a first modified example of the blood pressure measuring device 1. Figure 6 This is a cross-sectional view showing the flow path plate unit 22, pump 14, compression cuff 71 and sensing cuff 73 of the blood pressure measuring device 1 in the first modified example.

[0120] like Figure 5 and Figure 6 As shown, in the first modified example, the cuff structure 7 has the following structure: the pressing cuff 71 is connected to the sensing cuff 73 via the flow path plate unit 22; the sensing cuff 73 is connected to the atmosphere via the flow path plate unit 22.

[0121] The flow path section 22a of the flow path board unit 22 includes a first flow path 22c, a second flow path 22d, a third flow path 22e, and a fourth flow path 22f.

[0122] The third flow path 22e is a flow path that fluidly connects the compression cuff 71 and the sensing cuff 73. In this modified example, the third flow path 22e is connected to the compression cuff 71 and the second flow path 22d, and the compression cuff 71 and the sensing cuff 73 are connected via the second flow path 22d.

[0123] The fourth flow path 22f connects to the sensing cuff 73 and the atmosphere.

[0124] As a specific example, on the surface of the second flow path plate 132 opposite to the adhesive member 133, a third nozzle 132b3 and a fourth nozzle 132b4 are also formed as nozzles 132b connected to the sleeve structure 7.

[0125] The third nozzle 132b3 forms part of the third flow path 22e. The third nozzle 132b3 is connected to the pressing cuff 71. In addition, a first flow resistance element 121 is provided on the third nozzle 132b3.

[0126] The fourth nozzle 132b4 forms part of the fourth flow path 22f. The fourth nozzle 132b4 connects the fourth flow path 22f to the sensing cuff 73. The fourth nozzle 132b4 is connected to the sensing cuff 73. The fourth nozzle 132b4 is connected, for example, to the flow path body 92. A second flow resistance element 122 is provided on the fourth nozzle 132b4.

[0127] The notch 133a of the adhesive component 133 also has an opening corresponding to the third flow path 22e and an opening corresponding to the fourth flow path 22f.

[0128] Below, using Figure 7 and Figure 8 The second variation will be explained. Figure 7 This is a block diagram showing the structure of a second modified example of the blood pressure measuring device 1. Figure 8 This is a cross-sectional view showing the flow path plate unit 22, pump 14, pressure sensor 17, compression cuff 71 and sensing cuff 73 of the blood pressure measuring device 1 in the second modified example.

[0129] like Figure 7 and Figure 8 As shown, the cuff structure 7, apart from the structure of the first modified example, has the following structure: the pressing cuff 71 is connected to the sensing cuff 73 via a valve 123, which is an example of the fluid control unit 9 provided alongside the first flow resistance member 121.

[0130] If the pressure on the primary side is lower than the pressure on the secondary side, valve 123 opens. Specifically, if the pressure on the cuff 71 is greater than or equal to the pressure on the sensing cuff 73 side, valve 123 closes; if the pressure on the cuff 71 is lower than the pressure on the sensing cuff 73, valve 123 opens. This valve 123 is always closed, for example, when air is supplied to the cuff 71 and sensing cuff 73 during blood pressure measurement. Conversely, if the pressure on the cuff 71 is lower than the pressure on the sensing cuff 73, valve 123 opens. Valve 123 is, for example, a check valve.

[0131] For example, the opening pressure of valve 123 can be set to a pressure suitable for venting when pressing the cuff 71 and the sensing cuff 73. As a specific example, the opening pressure of valve 123 can be set to 0 mmHg, so that valve 123 opens when the pressure of pressing the cuff 71 is lower than the pressure of the sensing cuff 73.

[0132] The flow path section 22a also has a fifth flow path 22g. The fifth flow path 22g is a flow path equipped with valve 123 and connected to the pressing cuff 71 and the sensing cuff 73. In this modified example, the fifth flow path 22g is connected to the pressing cuff 71. In addition, the fifth flow path 22g is connected to the second flow path 22d and the third flow path 22e.

[0133] As a specific example, on the surface of the second flow path plate 132 opposite to the adhesive member 133, a fifth nozzle 132b5 is further formed as a nozzle 132b. The fifth nozzle 132b5 constitutes part of the fifth flow path 22g. The fifth nozzle 132b5 is connected to the pressing cuff 71. For example, a valve 123 is provided on the fifth nozzle 132b5.

[0134] The notch 133a of the adhesive component 133 also has a notch corresponding to the fifth flow path 22g.

[0135] [Second Embodiment]

[0136] Below, using Figure 9 and Figure 10 The blood pressure measuring device 1A according to the second embodiment will be described. Furthermore, the blood pressure measuring device 1A of the second embodiment differs from the blood pressure measuring device 1 of the first embodiment in that the adhesive member 133 includes a third flow path plate 135. In the second embodiment, structures that function the same as those in the first embodiment are given the same reference numerals and their descriptions are omitted.

[0137] Figure 9 This is a block diagram showing the structure of the blood pressure measuring device 1A according to the second embodiment. Figure 10 This is a cross-sectional view showing the structure of the pump 14, pressure sensor 17, flow path plate unit 22A, compression cuff 71, and sensing cuff 73 of the blood pressure measuring device 1A.

[0138] like Figure 9 and Figure 10 As shown, the blood pressure measuring device 1A includes, for example, a device body 3A, a belt 4, a collar 5, a cuff structure 7, and a fluid control unit 9. Furthermore, the belt 4, collar 5, cuff structure 7, and fluid control unit 9 are connected to... Figure 1 The first embodiment shown is the same.

[0139] The main body of the device 3A includes, for example, a housing 11, a display unit 12, an operation unit 13, a pump 14, an on / off valve 16, a pressure sensor 17, a power supply 18, a communication unit 19, a memory 20, a CPU 21, and a flow path board unit 22A. Regarding the main body of the device 3A, the flow path board unit 22A differs from that in the first embodiment. The housing 11, display unit 12, operation unit 13, pump 14, on / off valve 16, pressure sensor 17, power supply 18, communication unit 19, memory, and CPU 21 are as follows... Figure 1 and Figure 2 As shown, it is the same as the first embodiment.

[0140] In this embodiment, the fluid control unit 9 is provided on the flow path plate unit 22A for the cuff structure 7. The sensing cuff 73 of this embodiment is connected to the pump 14 in parallel with the pressing cuff 71 via the flow path plate unit 22A. Furthermore, the sensing cuff 73 is connected to the atmosphere via the flow path plate unit 22A.

[0141] The flow path unit 22A has a first flow path 131, a second flow path 132 and an adhesive member 133A.

[0142] In this embodiment, the second flow path plate 132 includes, for example, a flow path plate body 132a, a first nozzle 132b1, a second nozzle 132b2, and a third nozzle 132b3.

[0143] The adhesive member 133A is used to bond the first flow path plate 131 and the second flow path plate 132. The adhesive member 133 has a notch 133a, which, together with the first flow path plate 131 and the second flow path plate 132, forms a flow path portion 22a when the first flow path plate 131 and the second flow path plate 132 are bonded.

[0144] The adhesive member 133A includes: a third flow path plate 135; a first adhesive member 136 disposed on the surface of the third flow path plate 135 opposite to the first flow path plate 131; and a second adhesive member 137 disposed on the surface of the third flow path plate 135 opposite to the second flow path plate 132.

[0145] The third flow path plate 135 has a flow path 135a. The flow path 135a includes a fluid control section 9 for air to flow along the thickness direction of the third flow path plate 135. The flow path 135a is formed, for example, as a plurality of holes extending through the thickness direction of the third flow path plate 135. As an example of the fluid control section 9, a portion of these holes constitutes one or more throttling orifices.

[0146] In this embodiment, the third flow path plate 135 has a throttling orifice serving as a first flow resistance element 121 and a throttling orifice serving as a second flow resistance element 122. The third flow path plate 135 is an orifice plate. These first flow resistance elements 121 and second flow resistance elements 122 constitute a part of the notch 133a.

[0147] The first adhesive member 136 has a notch 133a1 as an opening or cut, which, when the first adhesive member 136 is bonded to the first flow path plate 131, serves to form a flow path 22a1 together with the first flow path plate 131 and the third flow path plate 135. The notch 133a1 is a part of the notch 133a. The first adhesive member 136 is, for example, composed of a plurality of double-sided adhesive tapes.

[0148] The second adhesive member 137 has an opening or cut notch 133a2, which, when the second adhesive member 137 is bonded to the second flow path plate 132, serves to form a flow path 22a2 together with the second flow path plate 132 and the second flow path plate 135. The notch 133a2 is a part of the notch 133a.

[0149] The flow path section 22a includes a first flow path 22c, a second flow path 22d, a fourth flow path 22f, and a sixth flow path 22h. The sixth flow path 22h is connected to the first flow path 22c and the second flow path 22d. In this embodiment, for example, the first flow resistance member 121 constitutes a part of the sixth flow path 22h. Furthermore, in this embodiment, for example, the second flow resistance member 122 constitutes a part of the third flow path 22e.

[0150] Because the blood pressure measuring device 1A is configured in this way, the flow path plate unit 22A does not need to have recesses formed on the first flow path plate 131 and the second flow path plate 132 to form the flow path portion 22a, thus miniaturization is possible. As a result, the blood pressure measuring device 1 can be miniaturized.

[0151] Furthermore, the first flow path plate 131 and the second flow path plate 132 are integrally bonded using the adhesive member 133A, thereby forming a flow path portion 22a in the notch 133a of the adhesive member 133A. Moreover, the adhesive member 133A has a third flow path plate 135, which has a flow path. Therefore, by forming a part of the flow path using the third flow path plate 135, the degree of freedom of the flow path in the flow path plate unit 22A can be increased. Furthermore, since the third flow path plate 135 does not have a recessed shape that forms a flow path, miniaturization of the flow path plate unit 22A is possible. In other words, miniaturization of the flow path plate unit 22A can be achieved while increasing the degree of freedom of the flow path.

[0152] Furthermore, by forming flow resistance elements 121 and 122, which serve as throttling orifices, on the flow path of the third flow path plate 135, a flow path plate unit 22A with internal throttling orifices can be obtained. Moreover, the throttling orifices are formed from a portion of the third flow path plate. Therefore, the shape accuracy of the throttling orifices can be improved.

[0153] Furthermore, by setting the flow path 135a formed on the third flow path plate 135 as one or more straight holes penetrating the third flow path plate 135 along the thickness direction, a flow path can be formed on the third flow path plate 135 even if the thickness of the third flow path plate 135 is reduced. As a result, miniaturization of the flow path plate unit 22A and the blood pressure measuring device 1A can be achieved.

[0154] Furthermore, although the second embodiment described above uses the following structure as an example, namely, the third flow path plate 135 as an example of a fluid control unit having flow resistance elements 121 and 122, which are throttling orifices configured as holes penetrating the thickness direction of the third flow path plate 135, it is not limited to this. In other examples, such as Figure 11 As shown, the flow path 135a of the third flow path plate 135 may also include a fluid control unit for air to flow along the surface direction of the third flow path plate 135. The fluid control unit may, for example, include flow resistance elements 121 and 122.

[0155] In this modified example, the first adhesive member 136 and the second adhesive member 137 may be a structure having a through-thickness hole that connects the flow path 135a in the third flow path plate 135 and the hole formed on the first flow path plate 131, or they may be a shape having an opening that forms a flow path extending in the surface direction.

[0156] Furthermore, the present invention is not limited to the embodiments described above. For example, in the examples of the blood pressure measuring devices of the various embodiments described above, the structure of using a notch 133a on a double-sided tape was described as an example of the adhesive members 133, 136, and 137, but it is not limited thereto. In other examples, the adhesive members 133, 136, and 137 may also have the notch 133a provided by combining multiple double-sided tapes. In addition, as other examples, the adhesive members 133, 136, and 137 may also be adhesives or hot melt adhesives.

[0157] Furthermore, in the above examples, the blood pressure measuring device 1 of the first embodiment was described as an example where the first flow resistance member 121 and the second flow resistance member 122 were respectively configured with the second flow path plate 132, but this is not the only example. In other examples, the first flow resistance member 121 and the second flow resistance member 122 may also be configured by reducing a portion of the flow path portion 22a. As an example, the first flow resistance member 121 and the second flow resistance member 122 may also be configured by reducing the flow path cross-sectional area of ​​the nozzle 132b or by reducing the flow path cross-sectional area formed by the notch 133a.

[0158] Furthermore, although the above examples illustrate that the first flow resistance element 121 and the second flow resistance element 122 are each composed of a single flow resistance element, this is not the only possible scenario. In other examples, such as... Figure 11 As shown, at least one of the first flow resistance element 121 and the second flow resistance element 122 can be provided in multiple ways. Figure 11 The example shown illustrates a structure with two first flow resistance elements 121.

[0159] Furthermore, the resistance of the first flow resistance element 121 and the second flow resistance element 122 can also be adjusted by adjusting the width of the fluid flow direction. As an example, it is shown... Figure 11 The structure shown has a width along the airflow direction of one first flow resistance element 121 that is longer than that of the other first flow resistance element 121 along the airflow direction. Furthermore, the resistance of the first and second flow resistance elements can also be adjusted by adjusting the cross-sectional area of ​​the flow path.

[0160] Furthermore, although the above example illustrates the structure in which flow path plate units 22, 22A are connected to the cuff structure 7 via nozzle 132b, it is not limited to this. In other examples, the structure could be as follows: the second flow path plate 132 has a hole forming part of the flow path section 22a, which is connected to the pressing cuff 71 or sensing cuff 73 of the cuff structure 7.

[0161] That is, as long as the flow path is formed by bonding the first flow path plate and the second flow path plate, the configuration or structure of the flow path or flow resistance component can be appropriately set.

[0162] Furthermore, in the first and second embodiments, as an example, the second flow path plate 132 is described as having a flow path plate body 132a and a nozzle 132b, with the flow path plate body 132a formed of a metallic material, such as a metal plate, and the nozzle 132b formed of resin, but it is not limited to this. In another example, the nozzle 132b may be formed of a metallic material. Moreover, the flow path plate body 132a of the second flow path plate 132 is formed of a metallic material; this is an example of the second flow path plate 132 being formed of a metallic material.

[0163] Furthermore, in the first and second embodiments, as an example, a structure in which the flow path plate bodies 132a of the first flow path plate 131 and the second flow path plate 132 are formed of a metallic material has been described, but it is not limited to this. It is also possible that at least one of the flow path plate bodies 132a of the first flow path plate 131 and the second flow path plate 132 is formed of a metallic material. Alternatively, it is also possible that at least one of the first flow path plate 131 and the second flow path plate 132 is formed of a metallic material. As an example, a structure including the first flow path plate 131 being formed of a metallic material is included. Alternatively, as an example, a structure including the second flow path plate 132, i.e., the flow path plate body 132a and the nozzle 132b, being formed of a metallic material is included.

[0164] That is, the present invention is not limited to the above-described embodiments, and various modifications can be made during the implementation phase without departing from its spirit. Furthermore, the embodiments can be appropriately combined to achieve combined effects. Moreover, the above-described embodiments include inventions at various stages, and various inventions can be extracted by appropriately combining the disclosed structural elements.
