Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings. The embodiments shown here are examples for embodying the technical idea of the present invention, and do not limit the present invention. In addition, all other feasible forms, examples, operational techniques, etc. that can be considered by those skilled in the art without departing from the gist of the present invention are included in the scope and gist of the present invention, and are described in the claims. It is included in the scope of the invention and its equality.

Further, the drawings attached to the present specification may be represented schematically by changing the scale, aspect ratio, shape, etc. from the actual product for convenience of illustration and comprehension. However, it does not limit the interpretation of the present invention.

In this specification, for convenience of explanation, XYZ coordinates are set as shown in the figure. That is, the "Z direction" is a direction along the vertical direction, the "X direction" is one direction orthogonal to the Z direction and parallel to the horizontal plane, and the "Y direction" is orthogonal to the Z direction and parallel to the horizontal plane. Of the other directions, it is a direction orthogonal to the X direction. Therefore, in the component measuring device 100 according to the present embodiment, the Z direction coincides with the thickness direction (vertical direction) of the housing 10, and the X direction is the longitudinal direction (front-back direction) along the long axis direction of the housing 10. They match, and the Y direction coincides with the lateral direction (width direction) of the housing 10.

Further, in the following explanation, when the explanation is given with ordinal numbers such as "first" and "second", they are used for convenience and do not specify any order unless otherwise specified.

The component measuring device 100 according to the embodiment of the present invention is a predetermined body fluid contained in a body fluid exuded by puncturing a user's biological surface (for example, skin) to be a puncture site by a separate puncture device (not shown). It is a device for measuring the component amount of the component of the above using a disposable inspection medium T. In the following embodiment, the component measuring device 100 is a self-monitoring blood glucose (self-monitoring of blood glucose; SMBG) device that measures the amount (blood glucose level) of the glucose component contained in the body fluid (blood) by the user himself / herself. This will be described as the form adopted in.

The component measuring device 100 is not limited to the SMBG device, but can also be used as a POCT (Point of Care Testing) device mainly operated by a medical worker. Further, since the component measuring device 100 is a device for measuring the specific amount of the component contained in the body fluid, the type of the body fluid and the amount of the component of the component to be measured are not limited to the configuration of the present embodiment.

[Constitution]
First, the configuration of the component measuring device 100 according to the present embodiment will be described with reference to FIGS. 1 to 6 as appropriate.

As shown in any one of FIGS. 1, 2, 4 to 6, the component measuring device 100 includes a housing 10, a cover member 20 provided along the shape of the outer surface of the housing 10, and a housing. A medium mounting portion 30 provided on the front surface 10a of the 10 and on which the inspection medium T is mounted is provided. The component measuring device 100 is used in combination with the inspection medium T.

Further, as shown in FIG. 3, in order to execute various processes related to the measurement of the amount of components in the body fluid, the component measuring device 100 includes a measuring unit 41, a temperature detecting unit 42, and a position detecting unit 43 as control systems. It includes a communication unit 44, a notification unit 45, a display unit 46, a power supply unit 47, a storage unit 48, and a control unit 49.

<Case>
The housing 10 has a substantially rectangular parallelepiped shape, and a part (particularly a corner portion) has an R shape having a predetermined curvature in consideration of portability and design. The display surface 46a of the display unit 46 is arranged on the flat surface (upper surface) 10b of the housing 10. The cover member 20 is rotatably supported between the protection position, which is the first position, and the eject operation position, which is the second position, on the side surfaces 10c facing each other in the width direction (Y direction) of the housing 10. A bearing guide portion 11 is provided for this purpose.

The shape of the housing 10 is not limited, and for example, a circular shape (including an ellipse shape, an oval shape, etc.) or a polygonal shape when viewed in a plan view (shape seen from the thickness direction (Z direction)) is adopted. You can also.

Here, the "protection position" is a position for preventing dust from entering the opening 31 of the medium mounting portion 30 provided on the front surface 10a of the housing 10. Further, the "eject operation position" is a position for removing (ejecting) the inspection medium T after the measurement is completed. Further, the protection position and the eject operation position also function as positions for switching the power ON / OFF of the component measuring device 100. That is, the protection position is a position where the power supply of the power supply unit 47 is turned off when the mobile phone is carried, and the eject operation position is a position where the power supply of the power supply unit 47 is turned on when the measurement is started.

The component measuring device 100 according to the present embodiment takes a protection position and an eject operation position depending on the position of the cover member 20 with respect to the housing 10. In the protected position, the push-in portion 21b of the cover member 20 is in a position to cover the opening 31. The eject operation position is a state in which the cover member 20 is located on the side opposite to the protection position in the front-rear direction of the housing 10, and the push-in portion 21b is in a position facing the rear surface 10d. The user can transition the cover member 20 between the protection position and the eject operation position.

The bearing guide portion 11 is provided on each of the left and right side surfaces 10c of the housing 10, and is provided with a bearing hole 12 that enables the cover member 20 to rotate and slide in the front-rear direction (X direction). The bearing hole 12 is an elongated hole extending along the axial direction (Y direction), and forms, for example, a substantially rounded rectangle. A pair of rotating shafts 22 provided on the inner surface of the base portion 21a of the cover member 20 are inserted into the bearing holes 12, respectively. As a result, the cover member 20 is rotatably held in the circumferential direction of the rotation shaft 22.

Further, the bearing hole 12 guides the sliding movement of the rotating shaft 22 in the front-rear direction (X direction) when the cover member 20 is ejected. The total length of the bearing hole 12 is set based on the stroke amount (movement amount) L1 when the cover member 20 is slid and moved. Here, the stroke amount L1 of the cover member 20 corresponds to the extrusion length of the inspection medium T by the medium holding portion 32. The stroke amount L1 (extrusion length) is the length of the inspection medium T and the opening at the rear end of the inspection medium T used by the user when the inspection medium T moves from the measurement position to the eject position. It is preferable to set it so that it can be removed from 31. At this time, it is more preferable to set it so that it can be removed from the component measuring device 100 without touching it.

Although not shown, a lid portion that is opened and closed when a battery functioning as a power supply portion 47 is attached / detached is provided at a predetermined portion (for example, the bottom surface (bottom surface) 10e) of the housing 10. When the battery is replaced, the lid portion is removed from the housing 10 to open the battery storage portion in which the battery is stored.

<Cover member>
The cover member 20 has a main body 21 having a shape along a part of the outer shape of the housing 10. The main body 21 has a plan view shape (shape seen from the Z direction) so as to cover three surfaces of the front surface 10a provided with the opening portion 31 of the medium mounting portion 30 in the housing 10 and both side surfaces 10c of the housing 10. It is roughly U-shaped. That is, the main body 21 is configured along three continuous surfaces of the substantially rectangular parallelepiped housing 10. The main body 21 has a plate-like shape that is continuous with the pair of bases 21a along the two opposing side surfaces 10c in the housing 10 and the tip side of the pair of bases 21a, and is provided integrally with the pair of bases 21a. It is provided with a push-in portion 21b. The inner surface of the push-in portion 21b faces the front surface 10a at the protection position and faces the rear surface 10d at the eject operation position. More specifically, in the protected position, the inner surface of the push-in portion 21b abuts on the front surface 10a. At the eject operation position, the inner surface of the pushing portion 21b is a position separated by the gap G without abutting on the rear surface 10d. Details of the gap G will be described later.

The cover member 20 functions as a part of the housing 10 when the component measuring device 100 is not used, and constitutes the outer shape of the component measuring device 100. The component measuring device 100 does not have a protruding portion or a convex shape on the outer surface composed of the housing 10 and the cover member 20 in the non-use form. That is, specifically, the housing 10 and the cover member 20 do not have a portion (protrusion) that protrudes outward in the region that is the outer surface of the component measuring device 100. As described above, since the component measuring device 100 does not have a convex shape on the outer surface when not in use, it is prevented from being caught by other parts around it when it is carried, and the portability is improved.

The main body 21 has a rotation shaft 22 of a cover member 20 projecting in the width direction of the housing 10. The rotating shaft 22 has a pair of shaft members (22a, 22b) for mounting on both side surfaces of the housing 10. The cover member 20 is supported by the housing 10 so as to be rotatable around the housing 10 around the rotation shaft 22.

On the inner surface of the base portion 21a of the main body 21,

shaft members

22a and 22b serving as a pair of rotating shafts 22 protruding toward the housing 10 along the width direction are provided. The

shaft members

22a and 22b are inserted and fitted into the bearing holes 12 (12a and 12b) of the bearing guide portion 11 provided in the housing 10, respectively. The rotating shaft 22 functions as a rotation center of the cover member 20 in a state of being fitted into the bearing hole 12 of the bearing guide portion 11, and also functions in the front-rear direction along the guide groove of the bearing hole 12 (the pushing portion 21b is a housing). It also has a function as a support for moving in the direction of approaching and separating from the rear surface 10d of 10.

Further, the tips of the

shaft members

22a and 22b pass through the bearing hole 12 and are inserted into the engagement hole 32a of the medium holding portion 32 described later. The rotating shaft 22 is attached to the bearing hole 12 by fitting a retaining ring (E-ring) (not shown) to the tip portion from the side opposite to the insertion direction into the bearing hole 12. .. As a result, the cover member 20 can rotate around the axis of the rotating shaft 22 and move in the axial direction along the bearing hole 12 with respect to the housing 10, but the movement in the width direction is restricted. It will be in the state of being done.

Further, the rotation shaft 22 is preferably at a position offset from the center in the longitudinal direction of the housing 10. In the present embodiment, the rotation shaft 22 is set from the opening 31 of the housing 10 to the rear side portion in the longitudinal direction. That is, the center of rotation of the main body 21 is larger in the outer size of the component measuring device 100 when the main body 21 is in the eject operation position than in the outer size of the component measuring device 100 when the main body 21 is in the protected position. Set to position.

As shown in FIGS. 4A or 4B, when the cover member 20 moves from the protective position to the eject operation position, between the inner surface and the rear surface 10d of the push-in portion 21b of the cover member 20 facing the rear surface 10d of the housing 10. A gap G is formed. As shown in FIG. 5, the separation dimension L2, which is the distance in the major axis direction in the gap G, is set to be longer than the stroke amount L1 of the cover member 20 by a predetermined length. Therefore, the arrangement position of the bearing guide portion 11 with respect to the side surface 10c is set to a position where the separation dimension L2 is longer than the stroke amount L1. As a result, when the cover member 20 is moved to the eject operation position, the external size of the component measuring device 100 becomes longer in the front-rear direction by the separation dimension L2 than when the main body 21 is in the protected position. The widthwise length of the gap G in the present embodiment is substantially the same as the widthwise length of the housing 10, but here, the widthwise length of the gap G is such that the cover member 20 moves with respect to the housing 10. It is permissible to include a clearance that can rotate without interference when doing so.

Typically, this type of measuring device is becoming smaller in size in order to improve portability. However, although the portability of the device improves as the miniaturization progresses, on the other hand, the operability may decrease due to the miniaturization for a specific user. However, the component measuring device 100 according to the present embodiment has a configuration in which the outer size of the device is increased when the cover member 20 is rotated from the protected position to the eject operation position as compared with the case where the cover member 20 is not used. There is. Therefore, the component measuring device 100 is a device having both portability and operability because the size of the component measuring device 100 is increased in use to facilitate operations such as eject operation, and the size is reduced to be smaller in non-use. ..

The cover member 20 only needs to be able to move the pushing portion 21b between the protection position and the eject operation position by the rotation operation with respect to the housing 10 around the rotation shaft 22 extending in the width direction. The cover member 20 can rotate along the circumferential direction of the rotation shaft 22, and as an example, the push-in portion 21b at the protected position faces the front surface 10a of the housing 10 → the bottom surface 10e → the rear surface 10d in this order. The housing 10 faces the "first rotation direction" that rotates the outer periphery of the housing 10 by approximately 180 ° and the push-in portion 21b at the protected position in the order of the front surface 10a → the flat surface 10b → the rear surface 10d of the housing 10. It may rotate in any of the "second rotation directions" in which the outer circumference is rotated by approximately 180 °. Further, the cover member 20 is configured to be rotatable with respect to the housing 10 in a direction opposite to the first rotation direction or the second rotation direction when returning from the eject operation position to the protection position.

Further, the cover member 20 is provided with a click mechanism (not shown) that gives a click feeling to the user to recognize that the movement is completed when the cover member 20 moves from the protected position to the eject operation position. As an example, the click mechanism is composed of a convex portion provided on the outer edge of the rotating shaft 22 and a concave portion provided on the inner edge of the bearing hole 12 and fitted with the convex portion when the cover member 20 moves to the eject operation position. May be done.

Further, the cover member 20 covers a part of the outer shape (front surface 10a and side surface 10c) of the housing 10 when not in use (when carried after the measurement is completed). Specifically, when the cover member 20 is in the protected position, the push-in portion 21b covers the opening portion 31 of the medium mounting portion 30. This makes it possible to prevent dust and other debris from entering the opening 31 when not in use.

As described above, in the component measuring device 100 according to the present embodiment, the cover member 20 can move between the protection position and the eject operation position in a state of being integrated with the housing 10 by a rotational operation. Further, the cover member 20 functions as a member for preventing dust and the like from entering the opening 31 of the medium mounting portion 30 when it is in the protective position, and when it is in the eject operation position, it is inspected after the measurement is completed. It functions as an operating member that performs an eject operation for removing the medium T. That is, the cover member 20 has both an eject function for removing the inspection medium T from the component measuring device 100 and a protection function for the opening 31 into which the inspection medium T is inserted. Therefore, in the component measuring device 100, the cover member 20 does not interfere with the measurement operation or the like, and is not unexpectedly separated from the housing 10 and lost.

<Medium mounting part>
The medium mounting portion 30 has an opening 31, and the inspection medium T is inserted and mounted. The inspection medium T is, for example, a disposable type test strip having an inspection unit T1 (see FIG. 7E) having a predetermined reagent at the tip thereof, and is discarded after measurement. The inspection unit T1 holds a reagent (coloring reagent) that specifically reacts with the substance to be measured in blood. The reagent may be held on a carrier such as a porous membrane capable of absorbing blood. By reacting with the reagent, blood develops a color with a color concentration corresponding to the amount of glucose contained in the blood.

The opening shape of the opening 31 may be formed according to the shape (cross-sectional shape) of the inspection medium T to be mounted. The opening shape of the opening 31 is set according to the shape of the inspection medium T to be mounted. Therefore, when the inspection medium T is not a plate shape like a test strip but a substantially columnar chip, the opening 31 has a shape to which the chip can be mounted.

Further, the medium mounting unit 30 is provided with a medium holding unit 32 for holding the mounted inspection medium T and for advancing the rear end portion of the inspection medium T from the opening 31 at the time of removal.

The medium holding portion 32 is provided so as to be movable along the axial direction in the housing 10, and is engaged with the cover member 20 via the rotating shaft 22. The medium holding portion 32 holds at least a part (particularly near the tip portion) of the inspection medium T inserted from the opening 31 for measurement (measurement position) and a position where the inspection medium T is removed (measurement position). It is provided so as to be movable along the long axis direction from the eject position). The medium holding unit 32 moves from the measurement position to the eject position as the cover member 20 ejected by the user moves. Since the inspection medium T is extruded from the opening 31 by a predetermined length, the inspection medium T after measurement can be removed from the component measuring device 100 without being touched by the user. The amount of extrusion of the inspection medium T by the medium holding portion 32 (corresponding to the operation amount of the cover member 20) is the size of the housing 10, the length of the inspection medium T in the longitudinal direction, and the amount of protrusion from the opening 31 (exposure). The length) is appropriately determined, but it is preferable that the inspection medium T is at least long enough to be detached from the opening 31. Further, the medium holding portion 32 may be configured to move by the urging force of the built-in elastic member 33 (coil spring or the like) when moving from the eject position to the measurement position.

Here, the operation of removing the inspection medium T by the cover member 20 will be described with reference to FIGS. 6A to 6C. In each figure, the cover member 20 is in a state of being rotationally moved to the eject operation position, and the components are shown by a two-dot chain line in order to make it easy to grasp the movement of the rotating shaft 22.

As shown in FIG. 6A, the inspection medium T is inserted through the opening 31 and mounted on the medium mounting portion 30. The user applies 0.5 to 10 μL of blood obtained by a puncture device (not shown) to the spot T2 at the distal end. After blood is introduced along a capillary channel (not shown) provided inside the test medium T, it is mixed with a reagent and the reaction with glucose proceeds. When the reaction product reaches the position corresponding to the measurement unit 41 in the capillary channel in the test medium T, the measurement unit 41 emits light having a predetermined wavelength from the light emitting element, and the blood obtained from the test unit T1. The reagent reaction amount based on the reagent reaction according to the glucose value in the test unit T1 is calculated from the amount of light obtained from the inspection unit T1. The measuring unit 41 outputs the measured measured value and the measurement end information indicating the measurement end to the control unit 49. The test medium T may have an air vent hole (not shown) for promoting blood introduction, and the air vent hole is provided at the end opposite to the spotting port T2 in the capillary channel. As described above, the component measuring device 100 measures the amount of glucose component in blood by the measuring unit 41 in a state where the test medium T is mounted on the medium mounting unit 30, and displays it as a blood glucose level.

Subsequently, as shown in FIG. 6B, when the cover member 20 is ejected after the measurement is completed, the medium holding unit 32 ejects from the measurement position while holding the inspection medium T as the cover member 20 moves. Start moving towards the position. The inspection medium T gradually increases the amount of protrusion (exposure amount) from the opening 31 as the cover member 20 moves, and when the cover member 20 is completely pushed in the X direction, the rear end portion is opened. It is in a state of protruding from 31 by a predetermined length. FIG. 6B shows a state in which the cover member 20 is completely pushed in and the medium holding portion 32 moves from the measurement position to the eject position. In this state, the inspection medium T is extruded from the opening 31 by a predetermined length, and is therefore removed from the component measuring device 100.

As shown in FIG. 6C, after the inspection medium T is removed, the medium holding portion 32 returns to the position before the eject operation together with the cover member 20 by the urging force of the elastic member 33.

Next, the control system of the component measuring device 100 will be described with reference to FIG.

The measuring unit 41 measures the amount of the component of the body fluid to be measured. In the component measuring device 100 according to the present embodiment, the measuring unit 41 optically measures the amount of the glucose component component in the blood. The measuring unit 41 has a light emitting element and a light receiving element (not shown), and is an optical system measuring device that irradiates the blood spread in the inspection unit T1 with the irradiation light from the light emitting element and detects the transmitted light by the light receiving element. It is configured. The measuring unit 41 is arranged in the housing 10 at a position where the inspection unit T1 of the inspection medium T held at the measurement position by the medium holding unit 32 can be inspected (for example, above the inspection unit T1 at the measurement position). To.

When the inspection medium T is mounted on the medium mounting section 30, the inspection section T1 on the proximal end side reaches the measuring section 41. The measuring unit 41 emits light having a predetermined wavelength from the light emitting element, and the test unit T1 determines the amount of reagent reaction based on the reagent reaction according to the glucose level in blood and the amount of light (transmittance) of the transmitted light from the inspection unit T1. taking measurement. The measuring unit 41 outputs the measured measured value and the measurement end information indicating the measurement end to the control unit 49.

Although the measuring unit 41 is configured to perform measurement by a colorimetric method that optically detects the blood glucose level in blood, other measuring methods can also be applied. Examples of the blood glucose measuring method include an electrode method in which a reagent is applied around an electrode to detect an electrical change associated with blood introduction, that is, a current generated between a detection electrode and a counter electrode. Further, as a matter of course, since the measuring unit 41 only needs to be able to measure the amount of the component in the body fluid to be measured, it is possible to appropriately change the device configuration according to the component to be measured.

The temperature detection unit 42 is composed of a known thermometer that measures the environmental temperature at the time of measurement. The temperature detection unit 42 outputs a temperature value based on the measured environmental temperature to the control unit 49.

The position detection unit 43 detects the position of the cover member 20. As an example, the position detection unit 43 uses a method of mechanically detecting each position of the protection position and the eject operation position based on the presence or absence of contact with the detection piece provided on the rotation shaft 22, an encoder or the like, and the rotation shaft 22. A method of electrically detecting the rotation angle of the above can be applied.

The position detection unit 43 is in a state where the push-in portion 21b of the cover member 20 faces the front surface 10a, the component measuring device 100 is not in use, and the cover member 20 protects the opening portion 31. Detect that. Further, in the position detecting unit 43, when the pushing portion 21b of the cover member 20 faces the rear surface 10d, the component measuring device 100 is in use, and the cover member 20 is in a state where the cover member 20 can be ejected at the end of the measurement. Detect that. The position detection unit 43 outputs the detected position information (protected position information, operation position information) of the cover member 20 to the control unit 49. Thereby, it is possible to control to turn off the power of the component measuring device 100 when the cover member 20 is in the protected position and turn on the power of the component measuring device 100 when the cover member 20 is not in the protected position. .. That is, the cover member 20 can also function as a power switch for the component measuring device 100.

Since the position detection unit 43 only needs to have a configuration capable of detecting that the cover member 20 remains at either the protection position or the eject operation position, the position detection method is limited to the above configuration. Not done.

The communication unit 44 is wired or wireless with another device (for example, an external server of a medical facility, various mobile terminals owned by a doctor in charge, etc.) to be connected via a communication network according to a predetermined protocol. It is a network interface that controls communication (including short-range wireless communication). The communication unit 44 transmits transmission data including a measured value indicating the measured component amount (blood glucose level) to the communication destination.

The notification unit 45 is composed of a notification device such as a speaker that outputs a notification sound such as a voice or a buzzer, a light emitting device that lights or blinks in various colors, a vibrator that generates a predetermined vibration, and the like. (For example, the start or end of a predetermined operation, a warning when an error occurs, a procedure guide, etc.) are notified to the user in an identifiable manner.

Further, when a predetermined time or more has elapsed from the acquisition of the measured value, the notification unit 45 notifies the medium mounting unit 30 to remove the inspection medium T under the control of the control unit 49. This prevents the user from forgetting to remove the inspection medium T. Alternatively, the inspection medium T is attached to the measurement unit 41 by comparing the blank signal acquired by the measurement unit 41 before the measurement value acquisition with the signal acquired by the measurement unit 41 after a predetermined time has elapsed from the measurement value acquisition. You may decide whether or not it is. The test medium T usually has an air vent hole at the distal end of the capillary tract to facilitate the introduction of blood. If the blood is left for a long time with the blood introduced into the capillary channel in the test medium T, the blood may seep out of the test medium T through the air vent holes. Therefore, it is preferable to remove the inspection medium T from the component measuring device 100 within a predetermined time from the measurement.

Further, the notification unit 45, under the control of the control unit 49, issues a notification prompting the cover member 20 to return from the eject operation position to the protection position after the measurement is completed and the inspection medium T is removed. As a result, the user can surely return the cover member 20 to the protected position. Further, the component measuring device 100 ensures portability and suppresses unnecessary power consumption of the power supply unit 47.

The display unit 46 is composed of a display device such as an LCD (Liquid Crystal Display) or an OLED (Organic Light Emitting Diode) display, and outputs the display contents in a format (characters, numbers, figures, etc.) that can be visually recognized by the user. Interface. The display unit 46 displays, for example, the amount of components in the body fluid measured by the measurement unit 41 (specifically, the value calculated by the calculation unit 49b of the control unit 49), and the notification content required for operation. It also displays (guidance display, measurement start / end display, etc.). The display content (display data) displayed on the display surface 46a on the display unit 46 is output from the control unit 49.

The power supply unit 47 is housed in the housing 10 and stores and mounts the battery that is the power source of the component measuring device 100. The battery is preferably a small battery such as a button battery in consideration of the portability of the component measuring device 100. The specifications of the battery used in the power supply unit 47 may be either a primary battery or a secondary battery. Further, the power supply unit 47 can use a physical battery such as a solar cell in combination with a chemical battery such as a button battery. Further, the power supply unit 47 may be provided with a function capable of supplying power or charging by connecting to an external power source (commercial power source or the like) by wire or wirelessly. The power supply unit 47 supplies the amount of electric power supplied to the circuits of each unit (measurement unit 41, temperature detection unit 42, communication unit 44, notification unit 45, display unit 46, storage unit 48, and control unit 49) constituting the component measuring device 100. It can be changed and contributes to power saving.

The storage unit 48 is a component measuring device such as various control programs necessary for driving the component measuring device 100, transmission data to a communication destination including the measured value measured by the measuring unit 41, and past values related to measurement for a predetermined period. It is composed of a known storage medium for storing various data used in 100.

The control unit 49 is composed of various processors including, for example, a CPU (Central Processing Unit), a ROM (Read only memory), a RAM (Random Access Memory), and the like. The control unit 49 controls each unit constituting the component measuring device 100 while activating a predetermined processing program to execute a predetermined processing. The control unit 49 includes, for example, a time measuring unit 49a composed of an RTC (Real-Time Clock), and measures the time according to a reference clock having a predetermined cycle supplied from a clock unit (not shown). The time clock by the time measuring unit 49a is used for generating the date and time when the measurement was performed and for measuring from the start of the measurement to the end of the measurement.

Further, the control unit 49 calculates the component amount (blood glucose level) of the component in the body fluid to be measured based on the detection value (color density) of the transmitted light optically detected by the measurement unit 41. To prepare for.

The calculation unit 49b has a function of appropriately performing correction processing in consideration of measured value fluctuation factors such as the environmental temperature (temperature value by the temperature detection unit 42) at the time of calculation processing. As a result, the calculation unit 49b can obtain a value closer to the true value with less measurement error. The calculation unit 49b outputs the calculated measured value to the display unit 46.

Further, the control unit 49 controls ON / OFF of power supply to each unit by the power supply unit 47 based on the position information from the position detection unit 43. When the protection position information is input from the position detection unit 43, the control unit 49 outputs a control signal for stopping the power supply to the power supply unit 47. As a result, the power of the component measuring device 100 is turned off. Further, when the operation position information is input from the position detection unit 43, the control unit 49 outputs a control signal for starting the power supply to the power supply unit 47. As a result, the component measuring device 100 is turned on and becomes an idle state.

Further, the control unit 49 includes a determination unit 49c that makes a predetermined determination.

When the measurement end information is input from the measurement unit 41, the determination unit 49c determines whether or not the inspection medium T mounted on the medium mounting unit 30 has been removed within a predetermined time (for example, several minutes). When the determination unit 49c determines that the inspection medium T has not been removed within a predetermined time, the determination unit 49c causes the notification unit 45 to execute a notification prompting the user to remove the inspection medium T. As a result, the user can prevent forgetting to remove the inspection medium T after the measurement is completed. The determination unit 49c may determine whether or not the inspection medium T has been removed, for example, depending on whether or not the cover member 20 is ejected, that is, whether or not the cover member 20 is moved in the major axis direction.

Further, the determination unit 49c determines whether or not the cover member 20 has moved from the eject operation position to the protection position within a predetermined time after the inspection medium T is removed. If the determination unit 49c determines that the cover member 20 has not moved from the eject operation position to the protection position within a predetermined time, the determination unit 49c notifies the user to move the cover member 20 to the protection position. Let 45 do it. As a result, the user can prevent the cover member 20 from forgetting to return the cover member 20 after the measurement is completed, and can suppress unnecessary power consumption of the power supply unit 47.

Further, the control unit 49 generates and processes to generate transmission data in which the measurement value calculated by the calculation unit 49b is associated with the measurement condition information (temperature information indicating the environmental temperature, the measurement time required for the measurement, etc.). It is provided with a generation processing unit 49d that performs a process of storing the transmitted data in the storage unit 48 and a process of controlling the transmission of the transmitted data toward the communication destination via the communication unit 44.

Although the timing unit 49a, the calculation unit 49b, and the generation processing unit 49d are all described as being included in the control unit 49, they may be configured separately from the control unit 49, respectively. Some of them may be included in the control unit 49.

Further, the control unit 49 is in a state where measurement by the measurement unit 41 is possible (a state in which the cover member 20 is in the eject operation position), and when the inspection medium T is not attached within a predetermined time, the user is notified. It is also possible to control the notification unit 45 so as to perform a notification prompting the attachment of the inspection medium T. Further, the control unit 49 may be configured to interrupt the measurement process when an unexpected situation such as the cover member 20 being operated during the measurement occurs. At that time, the control unit 49 causes the notification unit 45 to execute notification indicating a measurement error.

Next, an example of using the component measuring device 100 will be described with reference to FIGS. 7A to 7E.

Next, as shown in FIG. 7D, the user ejects the cover member 20 to push the pushing portion 21b toward the front end side (inspection medium T detaching direction) along the long axis direction. By the eject operation, the medium holding portion 32 moves along the axial direction from the measurement position to the eject position. As a result, the inspection medium T is pushed out from the opening 31 and is separated from the component measuring device 100. Thereby, the user can remove the inspection medium T. FIG. 7E shows a state in which the inspection medium T is removed from the component measuring device 100. After the inspection medium T is removed, the medium holding portion 32 moves toward the rear end side along the axial direction by the urging force of the elastic member 33 and returns to the original position (measurement position).

On the other hand, when the control unit 49 determines that the measurement process by the measurement unit 41 is not completed (S5-No), the control unit 49 loops the process of step S5 until the measurement process is completed.

In step S6, if the control unit 49 determines that the inspection medium T has been removed from the medium mounting unit 30 within a predetermined time (S6-Yes), whether or not the cover member 20 has moved from the eject operation position to the protection position. Judgment is made (S7). On the other hand, when the control unit 49 determines that the inspection medium T has not been removed from the medium mounting unit 30 within a predetermined time (S6-No), the control unit 49 transfers the inspection medium T from the medium mounting unit 30 to the user. The notification unit 45 is controlled so as to perform a notification prompting the user to remove the product (S8). After that, the control unit 49 loops the processes of steps S6 and S8 until the inspection medium T is removed.

In step S7, when the control unit 49 determines that the cover member 20 has moved to the protected position within a predetermined time (S7-Yes), the control unit 49 outputs a control signal for stopping the power supply to the power supply unit 47 (S9). End the process. As a result, the power of the component measuring device 100 is turned off, and the process is completed. On the other hand, when the control unit 49 determines that the cover member 20 has not moved to the protected position within a predetermined time (S7-No), the control unit 49 notifies the user to move the cover member 20 to the protected position. The notification unit 45 is controlled so as to perform (S10). After that, the control unit 49 loops the processes of steps S7 and S10 until the cover member 20 moves to the protected position.
