Description

[Technical field]

[0001] The present disclosure relates to a biological information measuring device that measures blood pressure, pulse waves, and the like. [Background technology]

[0002] There is known a cuff (hereinafter referred to as a "general-purpose cuff") that is connected to a vital information measuring device such as a blood pressure monitor or a vital information monitor via a relay hose. The vital information measuring device is placed on a desk or the like, and the subject wears the general-purpose cuff on his / her arm, and blood pressure, pulse wave, etc. are measured. The vital information measuring device and the relay hose are connected via a specified connector, and air is sent from the vital information measuring device to inflate the general-purpose cuff, thereby measuring blood pressure, pulse wave, etc.

[0003] The general-purpose cuff is composed of a rubber bag for inserting air, a cover (cuff cover) for covering the rubber bag, a relay hose for sending air to the rubber bag, and a designated connector attached to the end of the relay hose for connecting to a vital sign measuring device.

[0004] Also, a cuff (hereinafter, referred to as a "dedicated cuff") to which a portable vital information measuring device can be directly attached is known (Patent Document 1). As shown in Fig. 10 and Fig. 11, dedicated cuff 110 has cuff portion 112 into which the arm is inserted during measurement, and attachment portion 114 having a generally groove shape that is provided integrally with cuff portion 112 for attaching vital information measuring device 100.

[0005] The dedicated cuff 110 has a connecting part 118 for directly connecting and communicating with the vital information measuring device 100, and by fitting the vital information measuring device 100 into the attachment part 114, the vital information measuring device 100 and the cuff part 112 are communicated without an intermediate hose.

[0006] A plurality of engaging recesses 102 are formed on the side surface of the biological information measuring device 100. A plurality of engaging protrusions 116 are formed on the mounting part 114 corresponding to the engaging recesses 102. When the biological information measuring device 100 is fitted into the mounting part 114, the engaging recesses 102 and the engaging protrusions 116 engage with each other, and the two are integrally joined.

[0007] When measuring blood pressure, etc., the measurement area (upper arm, wrist, ankle, etc.) is inserted into cuff portion 112, and air is supplied and exhausted from the pressure unit built into bio-information measuring device 100 to cuff portion 112 via connecting portion 118, and blood pressure, pulse wave, etc. are measured.

[0008] Since the biological information measuring device 100 is small and lightweight, it can be easily carried around while attached to the dedicated cuff 110, and has the advantage of being able to perform measurements anywhere. In addition, the measured biological information such as blood pressure and pulse waves can be transmitted to an external device by, for example, a wireless device built into the biological information measuring device 100, and further, since air is supplied and exhausted directly to the cuff, a cordless and hoseless configuration can be realized.

[0009] [Patent Document 1] JP 2015-181579 A Summary of the Invention [Problem to be solved by the invention]

[0010] Since the biological information measuring device 100 is designed on the assumption that it will be attached to the dedicated cuff 110 for measurement, it may be a hindrance if it is attached to the arm, for example, when resting or sleeping. Also, from the viewpoint of operability and visibility, it is desirable to be able to measure even when it is separated from the body, like a stationary biological information measuring device.

[0011] An object of the present disclosure is to provide a vital information measuring device that can be attached to a dedicated cuff and that can be connected to a relay hose of a general-purpose cuff, allowing it to be placed at a location away from the arm and used. [Means for solving the problem]

[0012] The bioinformation measuring device disclosed herein has an air intake and exhaust section for connecting a dedicated cuff, and a housing onto which an attachment for connecting the air intake and exhaust section to a general-purpose cuff can be attached, and an identification recess is formed on the surface of the housing that contacts the attachment into which an identification protrusion formed on the attachment can fit.

[0013] In addition, the bioinformation measuring device disclosed herein has an air supply and exhaust unit for connecting a dedicated cuff, a housing onto which an attachment for connecting the air supply and exhaust unit to a general-purpose cuff can be attached, and an identification member for identifying the type of the attached attachment.

[0014] In addition, the attachment disclosed herein is an attachment that is attached to a housing of a bioinformation measuring device that is worn on a human body via a dedicated cuff attached to an air intake and exhaust section formed on the housing, in place of the dedicated cuff, and has a main body that is attached to the housing, a housing side connecting section that is provided on the main body and can be connected to the air intake and exhaust section, and a cuff side connecting section that is provided on the main body and communicates with the housing side connecting section, and to which an air intake and exhaust pipe of a general-purpose cuff can be connected. Effect of the Invention

[0015] According to the bioinformation measuring device disclosed herein, a choice can be made between measurement by attaching the device to a dedicated cuff and measurement by connecting to a general-purpose cuff via an attachment, making it possible to perform measurements according to the condition of the person being measured.

[0017] Hereinafter, a biological information measuring device according to an embodiment of the present disclosure will be specifically described with reference to the drawings. Note that each of the drawings of the embodiments described below is a schematic diagram and is not necessarily a precise illustration. Furthermore, in each drawing, substantially the same components are given the same reference numerals, and duplicated descriptions may be omitted or simplified.

[0018] FIG. 1 shows an attachment 1 attached to a vital information measuring device 50 capable of measuring blood pressure, pulse waves, etc. of both adults and newborns, and FIGS. 2 and 3 show the attachment 1 removed from the vital information measuring device 50.

[0019] The external shape of the biological information measuring device 50 is substantially the same as that of the conventional biological information measuring device 100 so that the biological information measuring device 50 can be attached to a dedicated cuff 110 for measurement. The biological information measuring device 50 has a flat rectangular parallelepiped shape as a whole, with an upper surface 52 of a housing 51 being flat, a side surface 53 being curved and convex outward (left and right in the drawing), and a lower surface 55 being curved and convex inward (upward in the drawing). The radius of curvature of the ridges between the surfaces is made large, giving the device an overall rounded shape.

[0020] On the top surface 52 of the housing 51, there are arranged a display unit 63 for displaying measurement results and the like, and operation switches 65, 67 for turning the power on and off, starting measurement, and various settings. On the side surface 53 of the housing 51, there are formed a plurality of engagement recesses 57 (in the illustrated example, two on each of the left and right side surfaces 53) for attaching the attachment 1 or the dedicated cuff 110. On the bottom surface 55 of the housing 51, there is provided an air supply and exhaust unit 59 for supplying and exhausting air to and from the cuff to measure blood pressure and the like. When the vital information measuring device 50 is attached to the dedicated cuff 110, the air supply and exhaust unit 59 is connected to the dedicated cuff 110, enabling air to be supplied and exhausted to and from the dedicated cuff 110.

[0021] The attachment 1 is formed in a groove shape that covers approximately the lower half of the biological information measuring device 50. The side wall portion 3 of the attachment 1 is curved to be convex outward so as to fit along the side surface portion 53 of the biological information measuring device 50, and the bottom wall portion 5 is curved to be convex inward so as to fit along the lower surface portion 55.

[0022] A plurality of engaging protrusions 7 (two on each of the left and right side walls 3 in the illustrated example) that engage with the engaging recesses 57 are formed on the inside of the side walls 3 of the attachment 1. When the vital information measuring device 50 is fitted into the groove shape of the attachment 1, the engaging recesses 57 engage with the engaging protrusions 7, and the two are integrally joined.

[0023] The bottom wall 5 of the attachment 1 is provided with a housing-side connecting part 21 that is connected to the air supply and exhaust part 59. A connector 23 to which a relay hose of a general-purpose cuff is connected is provided on the opposite side of the bottom wall 5 to the housing-side connecting part 21 (the underside of the bottom wall 5). When the attachment 1 is attached to the vital information measuring device 50, air can be supplied to and exhausted from the general-purpose cuff via the housing-side connecting part 21 and the connector 23.

[0024] 4, a connector stopper 27 is fitted onto the outside of connector 23 and attached to bottom wall portion 5, and connector 23 and housing side connecting portion 21 are connected by a tube 29. The rear half of connector 23, connector stopper 27 and tube 29 are covered from below by cover 25.

[0025] 3 and 5, a leg 11 for stably placing the attachment 1 on a flat surface such as a desk protrudes downward from the rear end (the right end in the figures) of the attachment 1. The cover 25 and the leg 11 allow the biological information measuring device 50 attached to the attachment 1 to be placed on a flat surface in an inclined state.

[0026] With the above configuration, if the vital information measuring device 50 is attached to the dedicated cuff 110, it is easy to carry and can be measured anywhere. Also, if the attachment 1 is attached to the vital information measuring device 50 and a general-purpose cuff is connected to the attachment 1, the vital information measuring device 50 can be placed away from the patient on a bed or a desk for measurement. When the vital information measuring device 50 is placed on a desk for measurement, the vital information measuring device 50 is inclined, making it easier to view the display unit 63.

[0027] In addition, the vital information measuring device 50 and the attachment 1 have a generally rounded, flat shape. This means that, for example, if they are placed on a bed while sleeping and the body touches them when turning over in sleep, the user is unlikely to feel pain. In addition, when the vital information measuring device 50 and the attachment 1 are carried in a pouch or the like, they do not get in the way and are easy to handle.

[0028] Next, a case where a newborn is measured using the biological information measuring device 50 will be described. In general, the size of the cuff and the pressure applied to the cuff are different when measuring an adult and when measuring a newborn. Therefore, the biological information measuring device 50 of the present disclosure is configured to control the pressure pump 80 that supplies and exhausts the cuff so that the pressure applied to the cuff can be changed when measuring an adult and when measuring a newborn.

[0029] In addition, the joint of the relay hose of the general-purpose cuff that is connected to the biological information measuring device is different between the adult measurement cuff and the newborn measurement cuff. Therefore, connectors 23 are prepared to which adult measurement cuffs can be connected and connectors 23 to which newborn measurement cuffs can be connected, and either connector 23 is attached to the attachment 1. In other words, the attachment 1 is classified into an adult measurement type and a newborn measurement type depending on the type of connector 23 attached.

[0030] When measuring a newborn, if the attachment 1 for measuring a newborn is mistakenly attached to a biological information measurement device 100 designed specifically for measuring adults, there is a risk of an accident in which high pressure for adults is applied to the newborn. Therefore, the attachment 1 of the present disclosure is designed to be attachable only to biological information measurement devices 50 capable of measuring newborns, and is provided with a means for preventing the attachment from being mistakenly attached to a biological information measurement device 100 designed specifically for measuring adults.

[0031] As shown in Fig. 6, a plurality of identification protrusions 9 (four in the illustrated example) for preventing erroneous attachment are formed on the bottom wall 5 of the attachment 1. Meanwhile, on the underside 55 of a vital information measuring device 50 capable of measuring a newborn, the same number of identification recesses 61 into which the identification protrusions 9 fit (four in the illustrated example) as the identification protrusions 9 are formed (see Fig. 3).

[0032] Since the conventional biometric information measuring device 100 designed specifically for measuring adults does not have an identification recess, the attachment 1 cannot be attached to the conventional biometric information measuring device 100, which prevents measurement of a newborn baby using pressure intended for an adult.

[0033] A magnet 31 for identifying the type of attachment 1 is embedded in the side wall 3 of the attachment 1 and is covered with a magnet cover 33 (FIG. 4). The magnetic force of the magnet 31 is different between when the attachment 1 is provided with the connector 23 for connecting an adult measurement cuff and when the attachment 1 is provided with the connector 23 for connecting a neonatal measurement cuff by varying the direction, number, strength, etc. of the magnetic poles of the magnet 31.

[0034] On the other hand, the vital information measuring device 50 has a built-in Hall element 78 as a component for detecting the magnetic force of the magnet 31, and it is possible to identify whether the attachment 1 is for measuring an adult or a newborn based on the detected magnetic force.

[0035] 7 shows an example of the functional configuration of the vital information measuring device 50. Upon receiving a detection signal from a Hall element (detection member) 78, a measurement subject determination section 72 of the control device 70 determines whether the attached attachment 1 is for measuring an adult or for measuring a newborn. The determination result is sent to a pressure pump control section 74 that controls the pressure pump. Meanwhile, an input signal instructing the start of measurement is sent from the operation switch 65. The pressure pump control section 74 drives and controls a pressure pump 80 based on the determination result and the input signal.

[0036] 8 shows a hardware configuration of the vital information measuring device 50. A memory 90, a non-volatile memory 84, an operation switch 65, a detection member 78, and a pressure pump 80 are connected to a CPU 82 of the control device 70. The CPU 82 acquires data from each part via a bus line and controls each part. A timer (not shown) is built in the CPU 82. The memory 90 is used as a work area for the CPU 82 to perform control.

[0037] An operating system 86 and a control program 88 are recorded in the non-volatile memory 84. The CPU 82 performs control in accordance with these programs. The control program 88 controls the pressure pump 80 and the like, and performs its functions in cooperation with the operating system 86. The operation switch 65 outputs an input signal when pressed.

[0038] The above hardware configuration is one example, and can be modified as appropriate, for example, by storing the program within the CPU 82 and not providing any memory, or by using no operating system.

[0039] 9 shows a flowchart of the pressurization process of the control device. When the attachment 1 is attached to the vital information measuring device 50 and the CPU 82 receives a detection signal related to the magnetic force of the magnet 31 from the detection member 78 (step S1), the CPU 82 judges whether the detection signal indicates that the attachment is for a newborn (step S2). If the detection signal is Yes, the CPU 82 waits until the operation switch 65 is pressed. When the operation switch 65 is pressed (step S3), the CPU 82 performs pressurization control for measuring the newborn (step S4).

[0040] If step S2 is No, the CPU 82 waits until pressing the operation switch 65. When the operation switch 65 is pressed (step S5), the CPU 82 performs pressurization control for measuring an adult (step S6).

[0041] The pressure pump control unit 74 controls the pressure pump 80 to change the pressure when measuring an adult and when measuring a newborn. Specifically, when measuring a newborn, the pressure is controlled to supply air to the cuff at a lower pressure than when measuring an adult. Therefore, the biological information measurement device 50 can measure with an appropriate pressure when measuring both an adult and a newborn.

[0042] (Modification) In the above example, the control device 70 controls the pressure pump 80 based on the detection signal from the detection member 78, but the device may be configured so that the user can set whether the device is for a newborn or an adult by inputting the setting using an input means such as a switch.

[0043] In the above example, the vital information measuring device 50 is provided with an air supply and exhaust section that serves both air supply and exhaust, but the air supply and exhaust sections may be provided separately in the vital information measuring device 50, and the attachment may be provided with a housing side connection section for air supply and a housing side connection section for exhaust that are connected to the air supply and exhaust sections, respectively, and the housing side connection section for air supply and the housing side connection section for exhaust may be configured to communicate with connector 23 to which the relay hose of the general-purpose cuff is connected.
