Description

  The present invention relates to a blood pressure measurement device that clamps a subject with an arm.

  With the aging of society, dealing with adult lifestyle-related diseases has become a major social issue. It is recognized that long-term blood pressure data collection is very important, especially for diseases related to high blood pressure. For example, a small blood pressure measuring device that is worn on a part of the outer ear so as not to interfere with the life of the subject has been developed so that it can be always worn (see, for example, Patent Document 1). This device is inserted into the external auditory canal or other parts of the external ear, and the pulsed light, pulse wave, electrocardiogram, body temperature, arterial oxygen saturation, blood pressure, etc. radiated into the subject are infrared light and visible light scattered light. It is calculated from the amount of received light. However, this apparatus does not include a cuff that compresses the subject, and the blood pressure measurement apparatus moves during blood pressure measurement, and the measurement location changes. Therefore, there is a problem in the accuracy of the measured blood pressure.

In the present application, the names of the auricles are based on Non-Patent Documents 1 and 2.

  On the other hand, in the method of measuring blood pressure by compressing a subject using a cuff and blocking blood flow, it is necessary to uniformly compress the portion to be measured and control the pressure.

  However, the subject such as the outer ear has a complicated shape (see, for example, Non-Patent Documents 1 and 2), and the shape varies depending on the individual. In addition, the blood vessel distribution in the subject is different for each subject. Therefore, the mounting position of the blood pressure measurement device that enables good ischemia differs for each subject.

This is a blood pressure measurement device.

  In the blood pressure measurement device according to the invention of the present application, the U-shaped structural arm, the U-shaped structural arm, or the V-shaped structural arm allows a predetermined range of the subject inserted between the two opposing ends to be measured. Can be sandwiched from both sides. Accordingly, the cuff disposed on substantially the entire inner surface of the arm can cover a certain range of the subject in contact with the cuff. Further, the cuff does not expand toward the arm side, but expands toward the subject inserted between the two opposite ends. Therefore, the cuff can press a certain range of the subject widely by the contact surface with the subject. Further, since the cuff is flexible, the contact surface is deformed in conformity with the shape even when the subject is complicated and has individual differences, and pressurizes the subject widely and uniformly. be able to. Therefore, regardless of the relative position between the blood pressure measurement device and the subject and the blood vessel distribution of the subject, the cuff can well block blood vessels in the subject over a wide range.

  Embodiments of the present invention will be described with reference to the accompanying drawings. The embodiment described below is an example of the configuration of the present invention, and the present invention is not limited to the following embodiment.

(Embodiment 1)
A blood pressure measurement device according to an embodiment of the first invention of the present application includes a U-shaped structure arm having two opposite ends, and a bag-like cuff that expands and contracts by supplying and discharging liquid or gas. It is an apparatus, Comprising: From the one edge part to the other edge part of the said two edge part, the said 2nd edge part of the said U-shaped structure arm exists substantially along the side which mutually opposes. The cuff is disposed on the entire surface.

  FIG. 1 is a schematic diagram showing a blood pressure measurement device 111 according to one embodiment of the first invention of the present application. The blood pressure measuring device 111 is attached to a tragus which is a part of the outer ear as a subject. The blood pressure measurement device 111 includes a U-shaped structural arm 10 and a cuff 15 as shown in FIG. In FIG. 1 and the following drawings, a display unit, a power supply unit, and other parts that can be realized by a normal technique related to the blood pressure measurement device 111 are not displayed.

  The U-shaped structural arm 10 is composed of a first end portion 11 and a second end portion 12, and is a U-shaped integrated structure that holds a subject between the first end portion 11 and the second end portion 12. . Further, from the first end 11 to the second end 12, the first end 11 and the second end 12 of the U-shaped structural arm 10 face each other, that is, along the side that holds the tragus. This surface is referred to as an arm inner surface 10a. The U-shaped structure arm 10 is large enough to hold the entire tragus, and the arm inner surface 10a has an area that can hold the tragus within a certain range.

  The U-shaped structural arm 10 is formed of a member that does not deform because it sandwiches the subject and receives pressure from the cuff 15. Moreover, in order to mount | wear with a part of outer ear, it is calculated | required that it is lightweight. For example, it is preferably formed of a metal such as an aluminum alloy or a magnesium alloy, or a plastic such as acrylic or polycarbonate.

  The cuff 15 applies pressure to the outside of the cuff 15. It is formed into a bag shape that expands and contracts when a liquid such as water or a gas such as air is supplied or exhausted, and is flexible enough to be deformed according to the shape of the tragus. The cuff 15 can be made of a stretchable and flexible material, for example, a rubber material such as silicon rubber or natural rubber.

  A pump for supplying liquid or gas is connected to the cuff 15 through a pipe, and a pressure sensor for measuring the pressure of the liquid or gas in the cuff 15 is also connected through the pipe. The pump and the pressure sensor can be installed in the U-shaped structure arm 10 or installed outside. Note that the pump, the pressure sensor, and the pipe are not shown in FIG. 1 and the drawings that will be described below because they are realized by ordinary techniques. The cuff 15 is expanded by supplying liquid or gas by the pump, and pressure can be applied to the outside of the cuff 15. On the other hand, when the liquid or gas supplied to the cuff 15 is discharged by the pump, the cuff 15 contracts and the pressure for compressing the outside can be reduced. The pressure of the liquid or gas in the cuff 15 can be measured by the pressure sensor, and the pressure in the cuff 15 measured by the pressure sensor can be used as a pressure for compressing the outside. Accordingly, the cuff 15 can adjust the pressure for pressing the tragus by adjusting the supply and discharge of the liquid or gas. The supplied liquid or gas may be discharged without using the pump by the elastic force of the rubber material of the cuff 15 and the opening and closing of a valve (not shown).

  The cuff 15 is disposed on substantially the entire surface of the arm inner surface 10 a of the U-shaped structure arm 10. Accordingly, the cuff 15 is folded back into a U shape along the shape of the arm inner surface 10a, and a surface that does not contact the arm inner surface 10a of the cuff 15 (hereinafter referred to as "a surface that does not contact the arm inner surface 10a of the cuff 15"). (Abbreviated as “expanded surface”). In the example of FIG. 1, a tragus is inserted between the cuff 15 and the opposing expansion surface.

  Since the U-shaped structural arm 10 is formed of a material that does not deform, when the cuff 15 is expanded, the cuff 15 does not expand toward the arm side, and the expansion surface expands. That is, when the U-shaped structure arm 10 holds the tragus, the tragus is pressed by the expansion surface on the first end portion 11 side and the expansion surface on the second end portion 12 side.

  FIG. 2 shows an example of wearing the blood pressure measurement device 111. FIG. 2 shows an example in which the blood pressure measuring device 111 is attached to the tragus 1. 2, the same reference numerals as those used in FIG. 1 have the same configuration and the same function. The second end portion 12 is inserted into the external auditory canal 9 and arranged on the external auditory canal 9 side of the tragus 1 (hereinafter, “the external ear canal 9 side of the tragus 1” is described as “inside the tragus 1”). The end 11 is mounted so as to be disposed on the opposite side of the ear canal 9 of the tragus 1 (hereinafter, “the opposite side of the ear canal 9 of the tragus 1” is described as “outside of the tragus 1”). In the blood pressure measurement device 111 in FIG. 2, the second end portion 12 is inside the tragus 1, and is therefore displayed with a broken line. Therefore, the cuff 15 can widely cover the outside of the tragus 1 and the inside of the tragus 1 and pressurize widely. Furthermore, since the cuff 15 is flexible, even if the tragus 1 has a complicated and individual shape, the expansion surface of the cuff 15 is deformed according to the shape of the tragus 1 when it is inflated. Therefore, the cuff 15 can pressurize the tragus 1 widely and uniformly. Therefore, regardless of the relative position of the blood pressure measuring device 111 and the tragus 1, the shape of the tragus 1, and the blood vessel distribution of the tragus 1, the cuff 15 can satisfactorily block blood vessels in the tragus 1 over a wide range.

  The blood pressure measurement device 111 operates as follows. In the following description, the cuff 15 is described as being expanded with air. Air is supplied by the pump until the pressure sensor reaches a predetermined value, and the pressure for pressing the tragus 1 of the cuff 15 is increased. When the cuff 15 is compressed, the blood vessels inside the tragus 1 are in a state of ischemia over a wide range. Thereafter, the air in the cuff 15 is gradually discharged, and the pressure for pressing the tragus 1 is reduced. As the pressure for pressing the tragus 1 decreases, blood that has been blocked in the tragus 1 begins to flow, and pulsation due to blood flow begins. The pulsation of the blood flow can be detected by the pressure sensor via the air in the cuff 15. When the pressure with which the cuff 15 presses the tragus 1 is further weakened, the pulsation of the blood flow becomes small and the pressure sensor cannot detect the pulsation. For example, the pressure of the pressure sensor when the pulsation of the blood flow begins can be a systolic blood pressure value, and the pressure of the pressure sensor when the blood flow pulsation cannot be detected can be a diastolic blood pressure value. . Further, the pulse rate can be calculated from the pulsation frequency detected by the pressure sensor. When the cuff 15 no longer presses the tragus 1, the blood pressure measurement device 111 ends the blood pressure measurement. The systolic blood pressure value and the diastolic blood pressure value are examples of blood pressure value names, and other names may be used.

  Therefore, the blood pressure measurement device 111 does not need to search for the optimal mounting position of the blood pressure measurement device for each subject, and can accurately measure blood pressure.

(Embodiment 2)
FIG. 3 is a schematic diagram showing a blood pressure measurement device 113 according to another embodiment of the first invention of the present application. The blood pressure measurement device 113 is attached to a tragus which is a part of the outer ear as a subject. In FIG. 3, the same reference numerals as those used in FIGS. 1 and 2 perform the same functions and the same operations. The blood pressure measurement device 113 uses a blood flow pulsation detection means as a photoelectric measurement using a light emitting element and a light receiving element from a pressure fluctuation measurement in the cuff 15 using the pressure sensor of the blood pressure measurement apparatus 111 of FIG. . Specifically, the difference from the blood pressure measurement device 111 of FIG. 1 is that the blood pressure measurement device 113 further includes a light emitting element 18 and a light receiving element 19 on the surface of the cuff 15. The cuff 15 may be provided inside the cuff 15 if a material that allows light to pass through is used. The light emitting element 18 irradiates the tragus 1 with irradiation light A having a wavelength that is easily absorbed by hemoglobin in the blood. The light receiving element 19 photoelectrically converts the scattered light B generated by the absorption and scattering of the irradiation light A due to the increase or decrease in the amount of hemoglobin in the blood accompanying the pulsation of the blood flow of the tragus 1 and outputs it as an electrical signal. The blood pressure measurement device 113 can detect the pulse wave corresponding to the pulsation of the blood flow by processing the fluctuation of the electric signal by a signal receiving circuit (not shown).

  The blood pressure measurement device 113 operates as described in the blood pressure measurement device 111 of the first embodiment, and the cuff 15 increases the pressure for pressing the tragus 1 until the pressure sensor reaches a predetermined value. In the process of reducing the pressure with which the cuff 15 compresses the tragus 1, the signal receiving circuit measures blood flow pulsation as the electrical signal. For example, the pressure of the pressure sensor when the signal receiving circuit starts to detect the fluctuation of the electric signal is the systolic blood pressure value, and the pressure sensor when the signal receiving circuit can no longer detect the fluctuation of the electric signal Can be used as the diastolic blood pressure value. Further, the pulse rate can be calculated from the frequency of fluctuation of the electrical signal.

  In the photoelectric measuring means, in order to obtain a pulse wave for blood pressure measurement, it is necessary to irradiate irradiation light A to a good ischemic position and receive scattered light B. However, depending on the shape of the tragus of the subject, the blood vessel distribution, or the relative position of the blood pressure measuring device 113 and the tragus 1, the location on the cuff 15 that can be successfully blocked for each subject or for each blood pressure measurement changes. become. Therefore, it is preferable to provide a plurality of light emitting elements 18 and a plurality of light receiving elements 19 on the surface or inside of the cuff 15.

  When the plurality of light emitting elements 18 irradiate the irradiation light A onto the tragus 1 pressed by the cuff 15, any of the irradiation light A is scattered at a place where the blood is well blocked and becomes scattered light B. The scattered light B is received by one of the light receiving elements 19. For example, it is possible to select a combination of the light emitting element 18 and the light receiving element 19 in which the pulse wave becomes the largest during blood pressure measurement. Therefore, blood pressure can be accurately measured regardless of the relative position of the blood pressure measurement device 113 and the tragus 1, the shape of the tragus 1, and the blood vessel distribution of the tragus 1.

  Therefore, the blood pressure measurement device 113 does not need to search for the optimal mounting position of the blood pressure measurement device for each subject, and can accurately measure blood pressure.

(Embodiment 3)
FIG. 4 is a schematic diagram showing a blood pressure measurement device 114 according to another embodiment of the first invention of the present application. The blood pressure measurement device 114 is attached to a tragus which is a part of the outer ear as a subject. 4, the same reference numerals as those used in FIG. 1 perform the same functions and the same operations. The blood pressure measuring device 114 uses pressure-sensitive conductive rubber from the pressure sensor as pressure measuring means for pressing the tragus. Specifically, the difference between the blood pressure measurement device 114 and the blood pressure measurement device 111 of FIG. 1 is that the blood pressure measurement device 111 does not include the pressure sensor that measures the pressure in the cuff 15, and the tragus 1 of the cuff 15. The pressure-sensitive conductive rubber 44 is provided on the contact surface.

  The pressure-sensitive conductive rubber is formed in a state where conductive particles such as carbon and metal are dispersed almost uniformly in an insulating rubber material. When no pressure is applied, the conductive particles are not in contact with each other. It shows a high electrical resistance value of about 40 MΩ. On the other hand, when a pressure is applied to the pressure-sensitive conductive rubber, the conductive particles begin to contact each other, and a conductive path is formed in the rubber. The conductive path increases according to the pressure, and the electrical resistance value is reduced to about 5Ω. That is, the pressure-sensitive conductive rubber has such a property that when a pressure is applied, the electric resistance value decreases and the pressure electric resistance value increases. The pressure-sensitive conductive rubber 44 is connected to an electric resistance measuring device (not shown) for measuring electric resistance, and the pressure at which the cuff 15 presses the tragus 1 can be measured as electric resistance.

  The blood pressure measuring device 114 operates as described in the blood pressure measuring device 111 of the first embodiment, and the cuff 15 increases the pressure to press the tragus 1 until the electric resistance value of the pressure-sensitive conductive rubber 44 reaches a predetermined value. To do. In the process of reducing the pressure with which the cuff 15 presses the tragus 1, the pressure-sensitive conductive rubber 44 can measure the pulsation of the tragus 1 as a change in the electrical resistance value together with the pressure with which the cuff 15 presses the tragus 1. (Hereinafter, “variation in electrical resistance value due to pulsation of tragus 1” is abbreviated as “pulsation electrical resistance value”). For example, the pressure converted from the electric resistance value of the pressure-sensitive conductive rubber 44 when the electric resistor starts to detect the pulsating electric resistance value can be detected as the systolic blood pressure value, and the electric resistor can detect the pulsating electric resistance value. The pressure converted from the electric resistance value of the pressure-sensitive conductive rubber 44 when it disappears can be used as the diastolic blood pressure value. Further, the pulse rate can be calculated from the frequency of the pulsating electrical resistance value.

  As described with reference to the blood pressure measurement device 113 in FIG. 3, since a good ischemic position changes for each subject and each blood pressure measurement, a plurality of pressure-sensitive conductive rubbers are arranged on the contact surface of the cuff 15 with the tragus 1. It is preferable. The pressure with which the cuff 15 presses the tragus 1 can be measured for each position of the arranged pressure-sensitive conductive rubber. Therefore, regardless of the relative position of the blood pressure measurement device 113 and the tragus 1, the shape of the tragus 1 and the blood distribution of the tragus 1, it is possible to measure the pressure at the place where the blood is well blocked, and measure the blood pressure with high accuracy. Can do.

  Therefore, the blood pressure measurement device 114 does not need to search for the optimum mounting position of the blood pressure measurement device for each subject, and can accurately measure blood pressure.

The difference between the blood pressure measurement device 115 and the blood pressure measurement device 111 of FIG. 1 is that the U-shaped structure arm 10 has a U-shape having an adjustment mechanism 55 that changes the distance between the first end portion 11 and the second end portion 12 as an alternative to the U-shaped structure arm 10. The mold structure arm 50 is provided.

  The U-shaped structure arm 50 includes a first arm 51 having a first end 11, a second arm 52 having a second end 12, and an adjustment mechanism 55. The first arm 51 and the second arm 52 are connected via an adjusting mechanism 55 so that the first end portion 11 and the second end portion 12 are opposed to each other. Similar to the U-shaped structure arm 10 described with reference to the blood pressure measurement device 111 in FIG. 1, the U-shaped structure arm 50 is a U-shaped integrated body that holds the subject between the first end portion 11 and the second end portion 12. It is a structure. Further, from the first end portion 11 to the second end portion 12, the first end portion 11 and the second end portion 12 of the U-shaped structural arm 50 face each other, that is, along the side where the tragus is sandwiched. This surface is referred to as an arm inner surface 50a. The U-shaped structure arm 50 is large enough to hold the entire tragus, and the arm inner surface 50a has an area that can hold the tragus within a certain range.

  The U-shaped structure arm 50 is formed of a lightweight and non-deformable member, similar to the U-shaped structure arm 10 described in the blood pressure measurement device 111 of FIG.

  The adjustment mechanism 55 has a function of adjusting the distance between the first end portion 11 and the second end portion 12 by changing the arm angle α formed by the first arm 51 and the second arm 52. The adjustment mechanism 55 can be, for example, a hinge that connects the first arm 51 and the second arm 52. Further, the first arm 51 and the second arm 52 may be connected by a plastic or elastic material such as metal or rubber.

  The blood pressure measuring device 115 is attached to the tragus in the same manner as the blood pressure measuring device 111 of FIG. Since the blood pressure measuring device 115 can adjust the distance between the first end portion 11 and the second end portion 12 when worn, the blood pressure measuring device 115 can be worn regardless of the thickness of the tragus, and the cuff 15 can be attached to the tragus. Can be adjusted to an appropriate contact state.

  The blood pressure measurement device 115 measures blood pressure as described in the blood pressure measurement device 111 of the first embodiment.

  Therefore, the blood pressure measurement device 115 does not need to search for an optimal position for mounting the blood pressure measurement device for each subject, and can accurately measure blood pressure.

The blood pressure measurement device 116 is attached to a tragus which is a part of the outer ear as a subject. 6, the same reference numerals as those used in FIGS. 1 and 2 have the same configuration and the same function. The difference between the blood pressure measurement device 116 and the blood pressure measurement device 111 of FIG. 1 is that the U-shaped structure arm 10 has a frame 61.

  Since the frame 61 receives pressure from the cuff 15, it is formed of a member that does not deform. Moreover, since the blood pressure measuring device 116 is attached to the tragus, the frame 61 is required to be lightweight. For example, it is preferably formed of a metal such as an aluminum alloy or a magnesium alloy, or a plastic such as acrylic or polycarbonate.

  The frame 61 is disposed so as to surround the cuff 15 along the arm inner surface 10a. That is, the frame 61 is present in the gap generated between the tragus and the arm inner surface 10a when the U-shaped structure arm 10 holds the tragus. Therefore, the frame 61 can prevent the cuff 15 supplied with liquid or gas from expanding in the gap direction. Only the contact surface of the cuff 15 with the tragus will be opened, and the contact surface of the cuff 15 with the open tragus will expand and efficiently transmit the pressure of the supplied liquid or gas to the tragus. be able to.

  The blood pressure measurement device 116 is attached to the tragus as described in the blood pressure measurement device 111 of the first embodiment, and measures blood pressure.

  In the U-shaped structure arm 50, the first arm 51 and the second arm 52 move via the adjustment mechanism 55, so that the frame 71 and the frame 72 are separated from the first arm 51 and the second arm 52 so as not to interfere with the operation. And installed separately. Accordingly, a gap is generated between the frame 71 and the frame 72. A bellows-like bellows frame 73 for preventing the cuff 15 from expanding from the gap may be disposed between the frames 71 and 72. That is, the frame 71, the frame 72, and the bellows frame 73 exist in the gap formed between the tragus and the arm inner surface 50a when the U-shaped structure arm 50 holds the tragus, and the cuff 15 is the tragus.
