The present invention relates to a blood pressure measurement device.
In recent years, blood pressure measurement devices used for measuring blood pressure are being used as means to check health status at home, as well as in medical facilities. A blood pressure measurement device detects vibration of the artery wall to measure blood pressure by, for example, inflating and contracting a cuff wrapped around the upper arm or the wrist of a living body and detecting the pressure of the cuff by a pressure sensor.
Such a blood pressure measurement device requires a measure against static electricity because electronic components are used. As a measure against static electricity used in existing watches and wearable devices, for example, a technique of connecting a metal housing to GND disclosed in Jpn. Pat. Appln. KOKAI Publication No. 2010 -286260 and a technique of providing a metal member inside and connecting the metal member to GND disclosed in Jpn. Pat. Appln. KOKAI Publication No. 2014 -165046 are known.
In the technique of connecting the metal housing to GND explained above, there is a problem in that the housing cannot be used for GND when the housing is made of resin or when the housing is used as an electrode. In the technique of providing the metal member inside and connecting the metal member to GND, an additional member is required for measures against static electricity, causing problems in terms of size and cost.
Therefore, an object of the present invention is to provide a blood pressure measurement device capable of suppressing an increase in size and cost and taking measures against static electricity.
According to one aspect, there is provided a blood pressure measurement device including: a housing; a flow path plate unit accommodated in the housing and at least partially formed of a conductive material; a pump connected to the flow path plate unit; a pressure sensor connected to the flow path plate unit; a cuff connected to the flow path plate unit and fluidly connected to the pump and the pressure sensor via the flow path plate unit; a printed circuit board accommodated in the housing and including GND; and at least one connection member that connects the GND of the printed circuit board and a part of the flow path plate unit formed of the conductive material.
According to this aspect, in the blood pressure measurement device, the GND of the printed circuit board and the flow path plate unit are connected by the connection member. Therefore, it is possible to take measures against static electricity using the flow path plate unit. In the blood pressure measurement device, the flow path plate unit, which is a component necessary for exerting the function of the blood pressure measurement device, is used for measures against static electricity. Therefore, it is possible to prevent the number of components from increasing for the measures against static electricity and prevent an increase in the size and cost of the blood pressure measurement device.
There is provided the blood pressure measurement device in the aspect described above, wherein the flow path plate unit includes: a first flow path plate formed of a metallic material; a second flow path plate formed of a metallic material; and an attachment member that attaches the first flow path plate and the second flow path plate, and the connection member is connected to at least one of the first flow path plate and the second flow path plate.
According to this aspect, the connection member only has to be connected to at least one of the first flow path plate and the second flow path plate formed of the metallic material. There is high flexibility in designing a connection position and the like.
There is provided the blood pressure measurement device in the aspect described above, wherein the attachment member includes a conductive material.
According to this aspect, since the first flow path plate and the second flow path plate are attached by the attachment member containing the conductive material, the first flow path plate, the second flow path plate, and the attachment member are electrically connected, and the volume of the flow path plate unit connected to GND is increased. Since the first flow path plate and the second flow path plate are conducted by the attachment member, the connection member only has to be connected to one of the first flow path plate and the second flow path plate.
According to the present invention, it is possible to provide a blood pressure measurement device capable of suppressing an increase in size and cost and taking measures against static electricity.

As illustrated in
The first belt 61 is referred to as a so-called a parent and is configured like a band. The first belt 61 includes a buckle 61c provided at one end portion thereof. The first belt 61 is rotatably held on the exterior case 31. The buckle 61c includes a frame-shaped body 61d having a rectangular frame shape and a buckle tongue 61e rotatably attached to the frame-shaped body 61d.

The second belt 62 includes a plurality of small holes 62a into which the buckle tongue 61e is insertable.
In the belt 4, the second belt 62 is inserted into the frame-shaped body 61d and the buckle tongue 61e is inserted into the small hole 62a, whereby the first belt 61 and the second belt 62 are connected as one piece and form, together with the exterior case 31, an annular shape along the circumferential direction of the wrist.
The curler 5 is formed of a resin material and is configured in a band-like shape that curves in such a manner as to follow along the circumferential direction of the wrist. For example, one end of the curler 5 is fixed to the wrist side of the device main body 3.
The curler 5 has hardness appropriate to provide flexibility and shape retainability. Here, the flexibility refers to deformation of the shape of the curler 5 in a radial direction at the time of application of an external force of the belt 4 to the curler 5.

As illustrated in
In the example of the present embodiment, in the cuff structure 7, the pressing cuff 71 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.
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 major surface of the pressing cuff 71 is fixed to the inner surface of the curler 5. For example, the pressing cuff 71 is attached to the inner surface of the curler 5 by a double-sided tape or an adhesive. By inflating, the pressing cuff 71 presses the back plate 72 and the sensing cuff 73 against the living body side.
The pressing cuff 71 includes, for example, an air bag 81.
The air bag 81 is a bag-like structure. In the present embodiment, since the blood pressure measurement device 1 is configured to use air with the pump 14, a description is given of a case of using the air bag. However, in a case of using fluid other than air, the bag-like structure may be a fluid bag such as a liquid bag.
The back plate 72 is stuck to a wrist-side surface of the pressing cuff 71 by a double-sided tape, an adhesive, or the like. The back plate 72 is formed of a resin material and is formed in a plate shape. The back plate 72 is formed of, for example, polypropylene and is formed in a plate shape with thickness of approximately 1 mm. The back plate 72 has a shape follow-up characteristic.
Here, the shape follow-up characteristic means a function by which the back plate 72 is deformable in such a manner as to imitate the shape of a contacted part of the wrist to be placed. The contacted part of the wrist means an area of contact with the back plate 72. The contact in this context means both direct contact and indirect contact.
The sensing cuff 73 is fixed to a wrist-side main surface of the back plate 72. The sensing cuff 73 comes in direct contact with an area where the artery of the wrist is present. The sensing cuff 73 is formed to have an identical shape to the back plate 72 or to have a smaller shape than the back plate 72 in the longitudinal direction and the width direction of the back plate 72. By inflating, the sensing cuff 73 presses an area where a palm-side artery of the wrist is present. By the inflated pressing cuff 71, the sensing cuff 73 is pressed against the living body side via the back plate 72.
In a concrete example, the sensing cuff 73 includes one air bag 91 and a flow path body 92.
Here, the air bag 91 is a bag-like structure. In the present embodiment, since the blood pressure measurement device 1 is configured to use air with the pump 14, a description is given of a case of using the air bag. However, in a case of using fluid other than air, the bag-like structure may be a liquid bag or the like.
The air bag 91 is constituted in a rectangular shape that is long in one direction. The air bag 91 is formed by, for example, combining two sheet members long in one direction and thermally welding edge portions thereof.
The flow path body 92 is, for example, integrally provided at a portion of one edge portion of the air bag 91 in the longitudinal direction. The flow path body 92 is provided at the end portion of the air bag 91 near the device main body 3. The flow path body 92 is formed in a shape that is long in one direction with width smaller than the dimension in the width direction of the air bag 91. The flow path body 92 includes, for example, a connection portion at a distal end thereof. The flow path body 92 is connected to the flow path unit 22a via the connection portion and forms a flow path between the flow path unit 22a and the air bag 91.
The fluid control unit 9 controls, for example, a supply amount of air supplied to the cuffs 71 and 73. The fluid control unit 9 is, for example, a fluid resistor such as an orifice or a check valve. In the example of the present embodiment, the fluid control unit 9 includes, for example, a plurality of flow rate resistors. The fluid control unit 9 controls a pressure ratio of air between the two cuffs 71 and 73 to be constant according to a flow rate resistance ratio between a plurality of flow rate resistors.
The fluid control unit 9 causes a pressure difference between the pressing cuff 71 and the sensing cuff 73 with the plurality of flow path resistors and controls a pressure ratio between the pressing cuff 71 and the sensing cuff 73 to be constant. The fluid control unit 9 sets a flow rate resistance ratio according to characteristics of the cuffs 71 and 73 of the blood pressure measurement device 1.
With the blood pressure measurement device 1 configured as explained above, the flow path plate unit 22 can be used as the GND by connecting the GND of the printed circuit board 231 and the flow path plate unit 22 formed of the metallic material using the connection member 25. The blood pressure measurement device 1 is capable of taking measures against static electricity and noise using the flow path plate unit 22. Since the flow path plate unit 22 is a component necessary for exerting the function of the blood pressure measurement device 1, the blood pressure measurement device 1 does not need to be provided with another component for measures against static electricity besides the connection member 25 by taking measures against static electricity using the flow path plate unit 22. Therefore, the blood pressure measurement device 1 can prevent an increase in the size of the device main body 3 and an increase in manufacturing cost.
The connection member 25 is configured to be connected to at least one of the first flow path plate 131 and the second flow path plate 132 formed of the metallic material. Therefore, the connection member 25 only has to be connected to a part of either the first flow path plate 131 or the second flow path plate 132. Flexibility in designing a connection position and the like is high.
Since it is unnecessary to use the housing 11 for measures against static electricity, flexibility of the housing 11 is also improved by forming the housing 11 using a resin material or using the housing 11 as an electrode. Note that, when the housing 11 is formed of a conductive material and is not used as an electrode, the housing 11 can also be used as measures against static electricity in addition to the flow path plate unit 22.
As explained above, with the blood pressure measurement device 1 according to the present embodiment, by connecting the flow path plate unit 22 to the GND of the mounting substrate 23 using the connection member 25, it is possible to suppress an increase in size and cost and take measures against static electricity.
Note that the present invention is not limited to the example of the embodiment explained above. For example, in the example explained above, an example is explained in which the connection member 25 is connected to the first flow path plate 131 of the flow path plate unit 22. However, the present invention is not limited thereto. For example, the connection member 25 may be connected to the second flow path plate 132 of the flow path plate unit 22.
The connection member 25 may be configured to be connected to both the first flow path plate 131 and the second flow path plate 132. For example, the attachment member 133 may be formed of a material containing a conductive material. The connection member 25 may be connected to one of the first flow path plate 131 and the second flow path plate 132. With the configuration in which both the first flow path plate 131 and the second flow path plate 132 are connected to the connection member 25, since the volume of the flow path plate unit 22 connected to the GND of the mounting substrate 23 (the printed circuit board 231) increases, it is possible to suitably take measures against static electricity.
A plurality of connection members 25 may be provided. For example, the pin 26 illustrated in
In the example explained above, the configuration in which the connection member 25 connects the flow path plate unit 22 and the GND of the printed circuit board 231 is explained. However, the present invention is not limited thereto. The detailed configuration of the connection member 25 can be set as appropriate if the connection member 25 can directly or indirectly connect the flow path plate unit 22 and the GND of the printed circuit board 231. That is, the connection member 25 may be configured to connect the flow path plate unit 22 and GND of another component connected to the GND of the printed circuit board 231.
Note that the present invention is not limited to the embodiment explained above and can be variously modified in an implementation stage without departing from the gist of the present invention. Embodiments may be implemented by being combined as appropriate as much as possible. In that case, a combined effect can be obtained. Further, the embodiment explained above includes inventions at various stages. Various inventions can be extracted by an appropriate combination of a disclosed plurality of constituent elements. For example, even if some constituent elements are deleted from all the constituent elements explained in the embodiment, if the problems can be solved and the effects can be obtained, a configuration from which the constituent elements are deleted can be extracted as an invention.
