Definitions
- the present invention relates to a blood pressure measuring device.
- blood pressure measuring devices used to measure blood pressure are used not only in medical facilities but also at home as a means of checking health conditions.
- blood pressure measuring devices measure blood pressure by inflating and deflating a cuff wrapped around the wrist of a living subject and detecting the pressure of the cuff using a pressure sensor, thereby detecting the vibration of the arterial wall.
- a technology is known for blood pressure measurement devices in which a hook-and-loop fastener is provided on the surface of a cuff to prevent the ends from shifting when both ends of the cuff are overlapped.
- a technology is known for blood pressure devices in which the cuff is placed on a band by inserting a pin provided on the cuff into a long hole in the band after sliding the band to adjust the band position (see, for example, Patent Document 2).
- the present invention aims to provide a blood pressure measuring device that can easily adjust the relative positions of the cuff and band and prevent the cuff from shifting in the width direction.
- a blood pressure measuring device includes a device body, a first cuff that is provided on the device body and presses against a living body, a band that is provided on the outer surface side of the first cuff and is wrapped around the living body, and a restricting member that restricts relative movement of the first cuff and the band in the width direction and allows relative movement of the first cuff and the band in the longitudinal direction.
- the restricting member restricts the relative movement of the band and the first cuff in the width direction, while allowing the first cuff and the band to move relative to each other in the longitudinal direction.
- the restricting member includes a sheet fixed to the device body side of the first cuff and separable from the tip side of the first cuff, a fixing member provided on opposing parts of the sheet and the first cuff and fixing the sheet and the first cuff, and a first restricting portion provided on the band, into which the sheet can be inserted and which restricts movement of the sheet in the width direction.
- the blood pressure measuring device can restrict movement of the first cuff away from the band by fixing the sheet inserted into the first restricting portion and the first cuff with a fixing member.
- the sheet, the fixing member, and the first restricting portion are formed to a length and/or position that allows the sheet to be inserted into the first restricting portion and the sheet and the first cuff to be fixed by the fixing member when the band is wrapped around the living body having the minimum and maximum circumferences for which the band is intended to be worn.
- the sheet inserted into the first restriction portion can be fixed to the first cuff, making it possible to measure blood pressure with high measurement accuracy in the living body that is expected to wear the device.
- the blood pressure measuring device of the above embodiment includes a second cuff that can overlap the first cuff on the outside of the first cuff, and the restricting member restricts the relative movement of the second cuff and at least one of the first cuff and the band in the width direction.
- the blood pressure measuring device when the blood pressure measuring device is attached to a living body and when the first cuff and the second cuff are inflated, the first cuff, the second cuff and the band do not shift in the width direction, and the relative positions of the first cuff, the second cuff and the band in the longitudinal direction can be easily adjusted. Therefore, the blood pressure measuring device can preferably compress the living body by inflating the first cuff and the second cuff, resulting in good measurement accuracy. Furthermore, by overlapping the first cuff and the second cuff, when inflated, the overlapping first cuff and the second cuff can more preferably compress the living body.
- the regulating member includes a sheet fixed to the device body side of the first cuff and separable from the tip side of the first cuff, a fixing member provided on a part of the sheet and the first cuff that face each other, a first regulating part provided on the inner surface of the band, into which the sheet can be inserted and which regulates the movement of the sheet in the width direction, and a second regulating part provided on the inner surface of the second cuff, into which the sheet can be inserted and which regulates the movement of the sheet in the width direction.
- the sheet inserted into the first and second restricting parts can be fixed to the first cuff, making it possible to measure blood pressure with high measurement accuracy in the living body to which it is intended to be attached.
- the sheet, the fixing member, the first restricting portion, and the second restricting portion are formed to a length and/or position that allows the sheet to be inserted into the first restricting portion and the second restricting portion and the sheet and the first cuff to be fixed by the fixing member when the band is wrapped around the living body having the minimum and maximum circumferences for which the band is intended to be worn.
- the sheet inserted into the first and second restricting parts can be fixed to the first cuff, making it possible to measure blood pressure with high measurement accuracy in the living body to which it is intended to be attached.
- the present invention provides a blood pressure measuring device that can easily adjust the relative positions of the cuff and band and prevent the cuff from shifting in the width direction.

Also, for example, the first restricting portion 7d restricts the relative movement of the first cuff structure 4 and the band 6 in the direction perpendicular to the width direction and longitudinal direction of the first cuff structure 4 and the band 6, that is, in the direction along the opposing direction of the first cuff structure 4 and the band 6, in the direction in which the first cuff structure 4 and the band 6 move apart. The first restricting portion 7d restricts the relative movement of the first cuff structure 4 and the band 6 in the width direction and the direction in which they move apart by engaging with the sheet 7a fixed to the first cuff structure 4.
- the first restricting portion 7d is formed in an annular shape and is formed so that the sheet 7a can be inserted therein.
- the first restricting portion 7d is provided on the inner surface of the band 6.
- the first restricting portion 7d is formed by fixing a sheet-like member in an annular shape to the inner surface of the band 6.
- the second regulating portion 7e regulates the relative movement of the first cuff structure 4 and the second cuff structure 5 in the width direction, and allows the relative movement of the first cuff structure 4 and the band 6 in the longitudinal direction without regulating it. Also, for example, the second regulating portion 7e regulates the relative movement of the first cuff structure 4 and the second cuff structure 5 in the direction perpendicular to the width direction and longitudinal direction of the first cuff structure 4 and the second cuff structure 5, i.e., in the direction along the opposing direction of the first cuff structure 4 and the second cuff structure 5.
- the second regulating portion 7e regulates the relative movement of the first cuff structure 4 and the second cuff structure 5 in the width direction and the direction in which they separate by engaging with the sheet 7a fixed to the first cuff structure 4. Therefore, the second restricting portion 7e, together with the sheet 7a and the first restricting portion 7d, restricts movement of the first cuff structure 4, the second cuff structure 5, and the band 6 in the width direction, and in the direction in which the first cuff structure 4 and the second cuff structure 5 face the band 6 and move away from each other.
- the second restricting portion 7e is formed in an annular shape and is formed so that the sheet 7a can be inserted therein.
- the second restricting portion 7e is provided on the inner surface of the band 6.
- the second restricting portion 7e is formed by fixing a sheet-like member in an annular shape to the inner surface of the band 6.
- the length of the first restricting portion 7d and the second restricting portion 7e in the longitudinal direction of the band 6 and the second cuff structure 5 can be appropriately set based on the ease of relative movement in the width direction of the first cuff structure 4, the second cuff structure 5, and the band 6, and the stability of the posture of the first cuff structure 4, the second cuff structure 5, and the band 6. That is, by increasing the length of the first restricting portion 7d and the second restricting portion 7e in the longitudinal direction of the band 6 and the second cuff structure 5, the length of contact with the sheet 7a in the width direction can be secured, so that the sheet 7a can be stably held in the width direction.
- the sheet 7a can be easily inserted and the frictional force in the sliding movement with the sheet 7a can be reduced, so that the first cuff structure 4, the second cuff structure 5, and the band 6 can easily move relatively in the longitudinal direction in a stable manner.
- the width of the opening into which the sheet 7a of the first restricting portion 7d and the second restricting portion 7e is inserted is larger than the width of the sheet 7a.
- the width of the opening into which the sheet 7a of the first restricting portion 7d and the second restricting portion 7e is inserted can be set appropriately based on the ease of inserting the sheet 7a, the ease of relative movement in the width direction of the first cuff structure 4, the second cuff structure 5, and the band 6, the stability of the posture of the first cuff structure 4, the second cuff structure 5, and the band 6, etc.
- the length and width of the first restricting portion 7d and the second restricting portion 7e can be set according to the desired function, etc.
- the first restricting portion 7d and the second restricting portion 7e may have the same shape, or the first restricting portion 7d and the second restricting portion 7e may have different shapes, such as by making one of the first restricting portion 7d and the second restricting portion 7e longer and/or wider than the other restricting portion.
- the length of the sheet 7a, the position of the pair of hook-and-loop fasteners 7b, 7c, the position of the first restricting portion 7d, and the position of the second restricting portion 7e are set to a length and/or position such that when the blood pressure measuring device 1 is attached to the wrist 300 having the minimum and maximum circumferences expected to be attached, and when the band 6 is wrapped around the wrist 300 having the minimum and maximum circumferences expected to be attached, the sheet 7a can be inserted into the first restricting portion 7d and the second restricting portion 7e, and the sheet 7a and the first cuff structure 4 can be fixed with the hook-and-loop fasteners 7b, 7c.
- the length of the sheet 7a, the position of the pair of hook-and-loop fasteners 7b, 7c, the position of the first restricting portion 7d, and the position of the second restricting portion 7e are set to a length and/or position such that when the blood pressure measuring device 1 is attached to the wrist 300 having the minimum and maximum circumferences expected to be attached, the first cuff structure 4 and the sheet 7a joined by the pair of hook-and-loop fasteners 7b, 7c do not interfere with the second restricting portion 7e and the first cuff structure 4 in the longitudinal direction.
- the first restriction portion 7d is positioned so as not to come into contact with the end of the second cuff structure 5 when the blood pressure measurement device 1 is worn on the wrist 300 having the minimum and maximum circumferences expected for wearing.
- the restricting member 7 can move the first cuff structure 4 and the second cuff structure 5 to a position suitable for attachment to the wrist 300. Furthermore, the restricting member 7 does not interfere with the second restricting portion 7e provided on the band 6 and the second cuff structure 5, and does not restrict the relative movement of the second cuff structure 5 and the band 6 in the wrapping direction around the wrist 300.
- such a restricting member 7 releases the connection of the hook-and-loop fasteners 7b and 7c provided on the first cuff structure 4 and the sheet 7a, and inserts the sheet 7a into the first restricting portion 7d and the second restricting portion 7e while separating the first cuff structure 4 from the sheet 7a. Then, the hook-and-loop fasteners 7c of the sheet 7a inserted into the first restricting portion 7d and the second restricting portion 7e are joined to the hook-and-loop fasteners 7b of the first cuff structure 4. In this way, the restricting member 7 restricts the relative movement in the width direction while allowing the relative movement in the longitudinal direction of the first cuff structure 4, the second cuff structure 5, and the band 6.

- the sensing cuff 54 is connected to the atmosphere, for example, via the flow path plate 24a and an orifice 24b provided in the flow path plate 24a.
- the orifice 24b between the first pressure cuff 52 and the sensing cuff 54, and the orifice 24b between the sensing cuff 54 and the atmosphere are set to a flow resistance that results in a desired pressure difference between the first pressure cuff 52 and the sensing cuff 54.
- the power transmitting device 100 includes a power source 101, a power transmitting unit 102, an antenna unit 103, and a power transmitting terminal 104.
- the power transmitting device 100 may include either the antenna unit 103 or the power transmitting terminal 104.
- the power source 101 is, for example, an AC adapter connected to a commercial power source or the like. 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.
- the power transmission unit 102 generates AC power as transmission power from the DC power supplied from the power source 101, and supplies it to the antenna unit 103.
- the power transmission unit 102 generates AC power with a frequency that is the same or approximately the same as the resonant frequency of the power transmission resonant circuit of the antenna unit 103, for example.

- the blood pressure measuring device 1 configured in this manner can restrict the widthwise movement of the first cuff structure 4 and the band 6 by the restricting member 7, and can also restrict the widthwise movement of the first cuff structure 4 and the second cuff structure 5. Therefore, the blood pressure measuring device 1 can prevent the first cuff structure 4, the second cuff structure 5, and the band 6 from shifting in the widthwise position when the device is attached to the wrist 300 and when the first cuff structure 4 and the second cuff structure 5 are inflated. Therefore, the band 6 can stably press the first cuff structure 4 and the second cuff structure 5 toward the wrist 300, so that the first cuff structure 4 and the second cuff structure 5 can suitably compress the wrist 300. Therefore, the blood pressure measuring device 1 has good blood pressure measurement accuracy.
- the restricting member 7 does not restrict the longitudinal movement of the first cuff structure 4, the second cuff structure 5, and the band 6, by wrapping the band 6 around the wrist 300, the first cuff structure 4 and the second cuff structure 5 also move in the longitudinal direction, and the first cuff structure 4 and the second cuff structure 5 can be wrapped around the wrist 300 in an appropriate manner.
- the restricting member 7 is arranged so that the first restricting portion 7d provided on the band 6 does not interfere with the second cuff structure 5, and does not hinder the relative longitudinal movement of the first cuff structure 4, the second cuff structure 5, and the band 6. Therefore, the blood pressure measuring device 1 can easily adjust the relative positions of the first cuff structure 4, the second cuff structure 5, and the band 6.
- the blood pressure measuring device 1 also has a first cuff structure 4 and a second cuff structure 5 that are fluidly connected and extend from the device body 3 on both sides in one direction of the device body 3.
- the device body 3 also has a protrusion (sensor portion) 31b1 on the bottom 31b of the housing 11, which is the back side, at a position away from the first cuff structure 4 and the second cuff structure 5, for example, at the center of the bottom 31b, as a space for arranging at least one of the biosensor 20 and the charging terminal 214. This allows the first cuff structure 4 and the second cuff structure 5, and at least one of the biosensor 20 and the charging terminal 214 to be arranged on the back side of the device body 3.
- the first cuff structure 4 and the second cuff structure 5 are fluidly connected via a fluid circuit 24 including a flow path plate 24a.
- the first cuff structure 4 and the second cuff structure 5 may also be fluidly connected directly to the first pressure cuff 52 and the second pressure cuff 62. With this configuration, the first cuff structure 4 and the second cuff structure 5 can be fluidly continuous even if they are provided and fixed to the housing 11 apart in one direction.
- the air bag 71 of the first pressure cuff 52 covers the area in which at least one of the two arteries 311, 312 is present, and the air bag 91 of the second pressure cuff 62 can overlap at least a portion of the air bag 71 of the first pressure cuff 52.
- the wrist 300 can be pressed by the first pressure cuff 52 and the second pressure cuff 62, so that sufficient pressure force can be secured to compress the artery even if the air bag 71 of the first pressure cuff 52 and the air bag 91 of the second pressure cuff 62 are not disposed on the back surface of the device main body 3.
- the air bag 71 of the first pressure cuff 52 and the air bag 91 of the second pressure cuff 62 can overlap by a predetermined length. Furthermore, when the blood pressure measuring device 1 is worn on the wrist 300 with the minimum circumference, the first cuff structure 4 and the second cuff structure 5 are long enough not to come into contact with the device body 3. Furthermore, the first cuff structure 4 and the second cuff structure 5 are not directly joined to the band 6.
- the blood pressure measuring device 1 can suitably press the artery with the first pressure cuff 52 and the second pressure cuff 62 because the air bags 71, 91 of the first pressure cuff 52 and the second pressure cuff 62 overlap and inflate. Therefore, the blood pressure measuring device 1 can place the biosensor 20 on the back side of the device body 3, and can perform accurate blood pressure measurement even if the air bags 71, 91 of the first pressure cuff 52 and the second pressure cuff 62 are not placed on the back side of the device body 3.
- the housing 11 has an air vent 31b6 on the bottom 31b, covered with a waterproof/breathable sheet 31b7, which allows ventilation inside the housing 11.
- the air vent 31b6 is located away from the first cuff structure 4 and the second cuff structure 5 at a location other than the protruding portion 31b1 of the bottom 31b, which prevents the air vent 31b6 from being blocked by the first cuff structure 4 and the second cuff structure 5.
- the air vent 31b6 is protected by the cuff cover 33 by providing the air vent 31b6 at a location covered by the cuff cover 33, which is located with a gap from the bottom 31b. Therefore, the blood pressure measuring device 1 can prevent dirt from adhering to the air vent 31b6 and the waterproof/breathable sheet 31b7, which prevents the ventilation function from being impaired.
- the ends of the first cuff structure 4 and the second cuff structure 5 that are located on the bottom 31b of the housing 11 are covered by the cuff cover 33, so that the movement of the first cuff structure 4 and the second cuff structure 5 in a direction away from the bottom 31b is restricted by the cuff cover 33. This makes it possible to prevent the first cuff structure 4 and the second cuff structure 5 from easily coming off the device main body 3.
- the blood pressure measuring device 1 is configured such that the various sensors 20a to 20c as the biosensor 20 and the charging terminal 214 are provided on the bottom 31b of the device body 3. Therefore, the device body 3 does not need to provide the biosensor 20 and the charging terminal 214 far from the device body from the substrate 25 provided inside the housing 11, making it possible to simplify wiring and provide a high degree of freedom in placement.
- the biosensor 20 is provided in the housing 11 with high rigidity, and can stably contact the wrist 300 when the blood pressure measuring device 1 is attached to the wrist 300, so that the biosensor 20 can suitably acquire bioinformation.
- the charging terminal 214 is exposed to the outside when the blood pressure measuring device 1 is removed from the wrist 300, making it easy to charge using the charging terminal 214.
- the blood pressure measuring device 1 simplifies the arrangement of the first pressure cuff 52 and the second pressure cuff 62 at the bottom 31b by fluidly connecting the first pressure cuff 52 and the second pressure cuff 62 via the fluid circuit 24 provided in the device body 3.
- the blood pressure measuring device 1 configured in this manner allows the first cuff structure 4, the second cuff structure 5, and the band 6 to move in the longitudinal direction by the restricting member 7, and restricts movement in the width direction, making it possible to easily adjust the relative positions of the first cuff structure 4, the second cuff structure 5, and the band 6 and to prevent the first cuff structure 4, the second cuff structure 5, and the band 6 from shifting in the width direction.

- the first pressure cuff 52 and the second pressure cuff 62 are connected while avoiding the protruding part 31b1, which is the sensor part, and therefore it is possible to prevent the first pressure cuff 52 and the second pressure cuff 62 from interfering with the protruding part 31b1 and inhibiting the function of the biosensor 20 and the charging terminal 214 provided on the protruding part 31b1.
