The pressing unit 140 may be configured such that the measuring cassette 200 mounted on the defining unit 120 and inserted into the inner space S1 is stably positioned in the inner space S1, It is possible to provide a pressing force such that the measuring cassette 200 inserted into the internal space S1 is pressed toward the one surface B1 of the inner surface of the defining portion 120. [

The pressing unit 140 may press the measuring cassette 200 facing the one surface B1 of the inner surface of the defining part 120 when the measuring cassette 200 is inserted into the inner space S1. The first pressing portion 142 and the second pressing portion 144 may be provided with the first pressing portion 142 and the second pressing portion 144 that elastically deform in contact with the other surface B3, A third pressing portion 146 (not shown) which provides an additional pressing force to the other surface B3 of the measuring cassette 200 after the pressing force is applied to the other surface B3 of the measuring cassette 200 by the second pressing portion 144, ).

The first pressing portion 142 and the second pressing portion 144 may be positioned at positions corresponding to both ends of the measurement cassette 200, respectively, and as shown in FIGS. 5 and 6, And is inserted into the internal space S1 of the cassette 200 to be elastically deformed to apply the restoring force due to the elastic deformation to the measurement cassette 200. [

When a pressing force of a predetermined magnitude is provided on the other surface B3 of the measuring cassette 200 by the first pressing portion 142 and the second pressing portion 144, The one surface B2 of the measuring cassette 200 is brought into contact with the abutting portion 125 of the prescribed portion 120. In this case,

The contact portion 125 may be a kind of hook that protrudes from the upper end of one surface B1 of the inner surface of the defining portion 120 in the other surface direction of the inner surface.

When the measuring cassette 200 is inserted into the internal space S1 while a pressing force by the first pressing portion 142 and the second pressing portion 144 is provided to the measuring cassette 200, The contact portion 125 may contact one surface B2 of the measurement cassette 200 opposed to one surface B1 of the inner surface of the defining portion 120 so that the insertion direction of the measurement cassette 200 is And may be an inclined direction D1 in the internal space S1.

[

The measuring cassette 200 can be guided to be stably positioned at an optimal position in relation to the light source of the measuring apparatus 100 by the third pressing unit 146, When insertion into the space S1 is completed, departure in the internal space S1 can be prevented as shown in FIG.

In other words, when the insertion of the measurement cassette 200 into the internal space S1 is completed, the measurement cassette 200 can be prevented from departing from the internal space S1 by the contact portion 125, This is because the upper end of one surface B2 of the measuring cassette 200 is caught by the abutting portion 125.

When the insertion of the measuring cassette 200 into the internal space S1 is completed, the pressing unit 140 provides the pressing force to the other surface B3 of the measuring cassette 200 by a restoring force by elastic deformation The upper end of the one surface B2 of the measurement cassette 200 can be kept in the state of being caught by the abutting portion 125. This allows the measurement cassette 200 inserted in the internal space S1 to be used to hold the biological sample It is possible to prevent the measurement cassette 200 from being separated from the internal space S1 during measurement of the analyte in the measurement cassette 200. [

8, when the measurement cassette 200 in which the biological sample and the at least one reagent are located is completely inserted into the internal space S1 of the measurement apparatus 100, the measurement cassette 200 is constantly The sample can be rotated clockwise or counterclockwise according to the pattern, whereby the biological sample and the reagent can be stirred or moved together to measure the amount of glycated hemoglobin in the biological sample.

In addition, the measurement apparatus 100 can also extract the ratio of the glycated hemoglobin to the total hemoglobin due to the measurement of the amount of the glycated hemoglobin.

After the amount of glycated hemoglobin in the biological sample is measured by the measuring device 100, the measuring cassette 200 must be separated from the internal space S1, And the external force of the user applied to one surface B2 of the substrate 200. [

An upper end of one face B2 of the measurement cassette 200 may be spaced apart from the contact portion 125 when an external force F of a user is applied to one face B2 of the measurement cassette 200, When the user pulls the measuring cassette 200 upward, it is separated naturally.

Here, it is a matter of course that the external force F of the user must be larger than the pressing force provided on the other surface B3 of the measurement cassette 200 by the pressing portion 140. [

As described above, the measurement apparatus 100 according to the present invention can easily and conveniently measure the measurement cassette 100 from the internal space S1 by the external force F of the user when the measurement of the analyte in the biological sample is completed Can be separated.

The measuring apparatus 100 according to the present invention is an apparatus for measuring an analyte of a biological sample based on a reaction characteristic of light emitted from a light source and essentially includes a light source and includes a light emitting element such as a photodiode And a light receiving element.

In other words, the measuring apparatus 100 measures the amount of glycated hemoglobin in the blood by the amount of light that is not specifically absorbed by the glycated hemoglobin in the blood and arrives at the light receiving element among the light amount of light of the specific frequency irradiated from the light emitting element You can do it.

Here, in order to measure the amount of HbA1c from the light amount of light emitted by the light emitting element and the light amount of light reaching the light receiving element, the relationship between the light amount of light emitted from the light emitting element and the light amount reaching the light receiving element depends on the amount of HbA1c .

However, due to the characteristics of the light source, that is, the characteristics of the light emitting device, the amount of light irradiated according to the use of the measuring apparatus 100 is reduced or increased by the inflow of disturbance light, The relationship between the light amount of the light emitted from the light emitting element and the light amount of the light reaching the light receiving element according to the amount needs to be corrected and correct measurement can be made despite the repetitive use of the measuring apparatus 100 only by the correction.

For this reason, the present invention provides a system and method for correcting a light amount change of a light source according to use of the measuring apparatus 100, a check cassette and a measuring apparatus provided in the system, and the like.

The check cassette 300 may be a cassette for correcting a change in light quantity of a light source of the measuring apparatus 100, unlike the measuring cassette 200 described with reference to FIGS. 1 to 9, And a second surface 320 disposed opposite the first surface 310.

The first surface 310 may have a first reaction surface 315 having a first specific reaction characteristic for a specific light and the second surface 320 may have a second specific reaction And a second reaction surface 325 that retains the properties of the second reaction surface 325.

Here, the first specific reaction characteristic may be a characteristic that defines the relationship between the light amount of the specific light emitted by the specific light emitting device and the light amount of light reaching the light receiving element after being reacted by the first reaction surface 315, The second specific reaction characteristic may be a characteristic that specifies the relationship between the light amount of the specific light emitted by the specific light emitting element and the light amount of light reaching the light receiving element after being reacted by the second reaction surface.

Hereinafter, a method of correcting the light amount of the light source using the light amount correction system 10 of the light source for the measuring apparatus will be described in detail.

12, a method of correcting a light amount of a light source using a light amount correcting system for a light source for a measuring apparatus according to the present invention includes inserting a check cassette 300 in a first state into an internal space S1 A second step S200 of extracting first reaction characteristic information of light emitted from the light source by the first reaction surface 310, a step S200 of inserting the check cassette 300 into the inner space (S400) of inserting the check cassette (300) into the internal space (S1) in a second state, separating the check cassette (300) from the first reaction surface (S1) A fifth step S500 of extracting second reaction characteristic information of light emitted from the light source, and a sixth step S600 of correcting a light amount change of the light source.

Here, the first state may be a state in which the check cassette 300 is rotated 180 degrees in the second state based on a direction in which the check cassette 300 is inserted into the internal space S1, and the second state may be a state in which the check cassette 300 May be rotated 180 degrees in the first state with respect to the direction in which they are inserted into the internal space S1.

Hereinafter, each step will be described in more detail with reference to FIGS. 13 to 18. FIG.

14 and 15, there is shown a light emitting device 300 having a first surface 310 having a first reaction surface 315 that retains a first specific reaction characteristic for a specific light, and a second surface 310 facing the first surface 310 Inserting the check cassette (300) including the second surface (320) having the second reaction surface (325) holding the second specific reaction characteristic for the specific light into the internal space (S1) in the first state The first step S100 may be performed.

13, the first step S100 is to select the mode of the measuring apparatus 100 to insert the check cassette 300 into the internal space S1 in the first state, And the insertion time of the check cassette 300 may be displayed, and the mode may include a measurement mode and a check mode.

In the case of the measurement mode, the analyte in the biological sample is measured using a measurement cassette (see FIGS. 1 to 9) in which the biological sample and the at least one reagent react with each other. In the check mode, the check cassette 300 May be a mode for correcting a change in the amount of light of the light source of the measuring apparatus 100.

After the check mode is selected, the measurement apparatus 100 can inform the user that the current time is the time at which the check cassette 300 should be inserted into the internal space S1.

In the above description, the mode selection step and the inserting time point of the check cassette 300 are included in the first step S100, but this is not essential.

In inserting the check cassette 300 into the internal space S1 in the first state, the second step S200 may proceed only when the check cassette 300 satisfies a predetermined first condition, The predetermined first condition may be various conditions.

For example, the predetermined first condition may be a condition for whether the check cassette 300 is fully inserted into the internal space S1 into the first state, a time condition for fully inserted, Time conditions, and the like.

First, when the predetermined first condition is a condition for whether the check cassette 300 is completely inserted into the internal space S1 into the first state, in order to satisfy the predetermined first condition, State.

Secondly, in the case where the predetermined first condition is a time condition required for the check cassette 300 to be completely inserted into the internal space S1, the state shown in FIG. 15 is satisfied in order to satisfy the first predetermined condition And the time that has elapsed is within the first predetermined time.

For example, if the predetermined first time is 5 seconds, the check cassette 300 is inserted into the internal space S1 until 5 seconds have elapsed after the check mode is selected and the check cassette 300 is inserted into the internal space S1. If it is not completely inserted into the space S1, the predetermined first condition is not satisfied.

In this case, the measuring apparatus 100 can output a signal enabling the control section to visually or auditorily identify it.

Third, in order to satisfy the first predetermined condition, when the predetermined first condition is a time condition in which the check cassette 300 is completely inserted into the internal space S1 and remains inserted, Lt; / RTI > for a second predetermined period of time.

For example, if the predetermined second time is 5 seconds, if the check cassette 300 is not completely inserted into the inner space S1 for at least 5 seconds, the predetermined first condition is not satisfied .

In this case, the measuring apparatus 100 can output a signal enabling the control section to visually or auditorily identify it.

In order to determine the first predetermined condition, the measuring apparatus 100 according to the present invention detects a sensor or the like capable of detecting whether or not the check cassette 300 is completely inserted into the internal space S1 Means and timers, and the like.

16, when the check cassette 300 is inserted into the internal space S1 in the first state, a first reaction (light) G of light emitted from the light source by the first reaction surface 315 A second step S200 of extracting characteristic information may be performed.

The second step S200 may be such that the first surface 310 is a surface located closer to the light source than the second surface so that a first reaction of the light emitted from the light source by the first reaction surface 315 So that the characteristic information can be extracted by the measuring apparatus 100.

In detail, the control unit may cause light to be emitted from the light emitting device toward the first reaction surface 315 when the check cassette 300 satisfies the predetermined first condition, And then the first reaction characteristic information can be extracted through the light amount of the light reaching the light receiving element.

Here, the first reaction surface 315 has the first specific reaction characteristic with respect to the specific light as described above. When the light emitted from the light emitting element is the same light intensity at the same frequency as the specific light, 1 < / RTI > specific reaction characteristics and the first reaction characteristics should be the same.

In other words, when the specific light is light of the light source, if the first reaction characteristic is different from the first specific reaction characteristic, it means that the light amount of the light source is changed.

On the other hand, the second reaction surface 325 of the second surface 320 may be formed by the light G emitted from the light source when the check cassette 300 is inserted into the internal space S1 in the first state, May not exhibit the reaction characteristics.

18, after the first reaction characteristic information of the light emitted from the light source by the first reaction surface 315 is extracted, a third step of separating the check cassette 300 from the internal space S1 (S300) may proceed.

Here, as shown in FIG. 17, the third step S300 may include a step of indicating a time when the check cassette 300 should be separated from the internal space S1, but it is not necessarily included .

In separating the check cassette 300 from the internal space S1, the fourth step S400 may be performed only if the check cassette 300 satisfies a predetermined second condition, 2 The condition can be various conditions.

For example, the predetermined second condition may be at least one of a condition for whether the check cassette 300 is completely separated from the internal space S1, a time condition for completely separating the check cassette 300, and the like.

First, when the predetermined second condition is a condition for whether or not the check cassette 300 is completely separated from the internal space S1, the condition shown in Fig. 18 must be satisfied in order to satisfy the predetermined second condition .

Secondly, if the predetermined second condition is a time condition required for the check cassette 300 to completely separate from the internal space S1, in order to satisfy the second predetermined condition, the state shown in Fig. 18 Time must be within a predetermined third time.

For example, if the predetermined third time is 5 seconds, the check cassette 300 is moved from the internal space (for example, 5 seconds) until 5 seconds have elapsed from the point in time at which the present time is notified to the user that the check cassette 300 should be separated. S1), the predetermined third condition is not satisfied.

In this case, the measuring apparatus 100 can output a signal enabling the control section to visually or auditorily identify it.

Meanwhile, the measuring apparatus 100 according to the present invention may include a sensor or the like capable of detecting whether or not the check cassette 300 is completely separated from the internal space S1 in order to determine the third predetermined condition Sensing means and a timer.

(S400) of inserting the check cassette (300) into the internal space (S1) into a second state different from the first state when the third step is performed while satisfying a predetermined second condition Can proceed.

As described above, the second state may be rotated 180 degrees with respect to the first state, and the fourth step (S400) may include displaying the insertion time of the check cassette 300 , It is not necessary.

In inserting the check cassette 300 into the internal space S1 in the second state, the check cassette 300 may proceed to the fourth step S400 only when the predetermined third condition is satisfied, The predetermined third condition may be various conditions.

For example, the predetermined third condition may be a condition for whether the check cassette 300 is fully inserted into the internal space S1 into the second state, a time condition for fully inserted, Time conditions, and the like.

First, when the predetermined third condition is a condition for whether the check cassette 300 is completely inserted into the internal space S1 into the second state, in order to satisfy the third predetermined condition, State (at this time, the check cassette 300 is inserted into the second state).

Secondly, if the predetermined third condition is a time condition required for the check cassette 300 to be completely inserted into the internal space S1, in order to satisfy the third predetermined condition, Check cassette 300 is inserted into the second state) should be within a predetermined fourth time.

For example, if the predetermined fourth time is 5 seconds, if the check cassette 300 is not completely inserted into the internal space S1 until 5 seconds have elapsed from the time point at which the check cassette 300 is inserted, The specified third condition is not satisfied.

In this case, the measuring apparatus 100 can output a signal enabling the control section to visually or auditorily identify it.

Thirdly, in order to satisfy the predetermined third condition, when the predetermined third condition is a time condition in which the check cassette 300 is completely inserted into the internal space S1 and remains inserted, State (at this time, the check cassette 300 is inserted into the second state) for a predetermined fifth time.

For example, if the predetermined fifth time is 5 seconds, if the check cassette 300 is not completely inserted into the internal space S1 for at least 5 seconds, the predetermined third condition is not satisfied .

In this case, the measuring apparatus 100 can output a signal enabling the control section to visually or auditorily identify it.

Meanwhile, the measuring apparatus 100 according to the present invention detects a sensor or the like that can detect whether or not the check cassette 300 is completely inserted into the internal space S1 to determine the third predetermined condition Means and timers, and the like.

When the check cassette 300 is inserted into the internal space S1 in the second state while satisfying the predetermined third condition, the second reaction characteristic of the light emitted from the light source by the second reaction surface 320 A fifth step S500 of extracting information may be performed.

In the fifth step S500, the second surface 320 is a surface located closer to the light source than the first surface 310, and the second surface 320 is irradiated with light from the light source by the second reaction surface 325 So that the second reaction characteristic information of the light to be emitted is extracted by the measurement apparatus 100.

In detail, the control unit may cause light to be emitted from the light emitting element toward the second reaction surface 325 when the check cassette 300 satisfies the predetermined third condition, The second reaction characteristic information can be extracted through the light amount of the light reaching the light receiving element.

Here, the second reaction surface 325 has the second specific reaction characteristic with respect to the specific light as described above. When the light emitted from the light emitting element is the same light intensity at the same frequency as the specific light, 2 < / RTI > specific reaction characteristics and the second reaction characteristics should be the same.

In other words, when the specific light is light of the light source, if the second reaction characteristic is different from the second specific reaction characteristic, it means that the light amount of the light source is changed.

On the other hand, when the check cassette 300 is inserted into the internal space S 1 in the second state, the first reaction surface 315 of the first surface 310 is in contact with the light emitted from the light source Characteristics may not appear.

After the fifth step S500, a sixth step S600 of correcting a light amount change of the light source according to the use is performed based on the extracted first reaction characteristic information and the second reaction characteristic information .

The control unit calculates the amount of light emitted from the light emitting device and the amount of light received from the light emitting device based on the first reaction characteristic information and the second reaction characteristic information extracted through the second step S200 and the fifth step S500 The relationship between the amount of light reaching the element and the amount of light reaching the element can be corrected.

In this case, the controller may correct the light amount change of the light source by using the average of the first reaction characteristic information and the second reaction characteristic information, but the present invention is not limited thereto, It is also possible to correct a change in the amount of light.

The sixth step S600 may include a step of indicating a time when the check cassette 300 should be separated from the internal space S1, but it is not necessarily included.

The position of the first reaction surface 315 in the case where the check cassette 300 is inserted into the internal space S1 in the first state in the first step S100 and the position of the first reaction surface 315 in the fourth step S400, The position of the second reaction surface 325 when the check cassette 300 is inserted into the internal space S1 into the second state may be the same as each other.

The position of the first reaction surface 315 with respect to the first surface 310 and the position of the second reaction surface 325 with respect to the second surface 320 may be identical to each other.

The position of the first reaction surface 315 with respect to the first surface 310 may be determined based on the direction in which the check cassette 300 is inserted into the internal space S1 in the first state, And the position of the second reaction surface 325 with respect to the second surface 320 is a direction in which the check cassette 300 is inserted into the internal space S1 in the second state As shown in FIG.

When the check cassette 300 is inserted into the internal space S1 in the first state, the first reaction surface 315 is positioned at a predetermined position, When the check cassette 300 is inserted into the inner space S1 in the second state, similarly, the second reaction surface 325 is located at an optimal position with respect to the light source Because they must be placed in an optimal position in a stable relationship.

On the other hand, when the first reaction characteristic information is extracted through the second step S200, the second reaction surface 325 of the second surface 320 may have a positional relationship between the light source and the second reaction surface 325 The reaction characteristic of the light emitted from the light source may not be displayed. Similarly, when the second reaction characteristic information is extracted through the fifth step S500, the first reaction surface of the first surface 310, The light source 315 may not exhibit the reaction characteristics with respect to the light emitted from the light source.

The measurement apparatus 100 includes a measurement cassette guide 130 for allowing the measurement cassette 300 to be inserted into the internal space S1 only in a specific state, as described with reference to Figs.

However, the measurement cassette guiding unit 130 may be configured such that the check cassettes 300 are moved in the first state and the second state, respectively, through the first space S100 and the fourth space S400, S1, it may not interfere with the check cassette 300.

This is because the check cassette 300 must be inserted into the internal space S1 in both the first state and the second state unlike the measurement cassette 200. [

When the light emitted from the light emitting element is the same light intensity at the same frequency as the specific light, 1 < / RTI > specific reaction characteristics and the first reaction characteristics should be the same.

In other words, when the specific light is light of the light source, if the first reaction characteristic is different from the first specific reaction characteristic, it means that the light amount of the light source is changed.

Referring to FIG. 26, after extracting the first reaction characteristic information of light emitted from the light source by the first reaction surface 415, the first reaction characteristic information of the first check cassette 400 is separated from the internal space S1 Step S30 may be performed.

The fourth step S40 of inserting the second check cassette 500 into the inner space S1 may be performed while the third step is performed while satisfying the predetermined second condition.

The fourth step may include indicating the insertion time of the second check cassette 500, but is not essential.

In inserting the second check cassette 500 into the internal space S1, the second check cassette 500 may proceed to the fourth step S40 only if it satisfies a predetermined third condition, The predetermined third condition may be various conditions.

When the light emitted from the light emitting element is the same light intensity at the same frequency as the specific light, 2 < / RTI > specific reactant characteristics and the second reactant characteristics should be the same.

In other words, when the specific light is light of the light source, if the second reaction characteristic is different from the second specific reaction characteristic, it means that the light amount of the light source is changed.

After the fifth step (S50), a sixth step (S60) of correcting a light amount change of the light source according to use is performed based on the extracted first reaction characteristic information and the second reaction characteristic information .

The control unit controls the amount of light emitted from the light emitting device and the amount of light received from the light emitting device according to the amount of glycated hemoglobin based on the first reaction characteristic information and the second reaction characteristic information extracted through the second step S20 and the fifth step S50 The relationship between the amount of light reaching the element and the amount of light reaching the element can be corrected.
