[0001] The present invention relates to a sensor strip, a strip connector, and a measuring device including the sensor strip,

The present invention relates to a sensor strip, a strip connector and a measuring device including the sensor strip, which can correct the measurement error of the sensor strip.

However, the sensor strip may include inherent measurement errors for the respective sensor strips due to the characteristics of the manufacturing process, and different measurement errors may be included in each sensor strip production.

Conventionally, in order to correct a measurement error included in a manufacturing process of a sensor strip, a unique code corresponding to a measurement error is produced at the time of production of the sensor strip, and then a unique code is input to the blood glucose measurement device To compensate for the measurement error.

In the following detailed description of the preferred embodiments of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. In the drawings, like reference numerals are used throughout the drawings.

In addition, in the entire specification, when a part is referred to as being 'connected' to another part, it may be referred to as 'indirectly connected' not only with 'directly connected' .

1 is a block diagram showing a measuring apparatus according to an embodiment of the present invention.

Referring to FIG. 1, a measurement apparatus according to an exemplary embodiment of the present invention may include a measurement unit 100, an operation unit 200, a display unit 300, and a temperature measurement unit 400.

Hereinafter, a measuring apparatus according to an embodiment of the present invention will be described with reference to FIG.

The measuring unit 100 can perform measurement on the supplied specimen and output a specimen signal corresponding to the concentration of the specimen. At this time, the measuring unit 100 may output a correction code signal including information on a measurement error of the measurement unit 100, and may output the sample signal and the correction code signal generated by the measuring unit 100, 200). Specifically, the measuring unit 100 may include a sensor strip 110 and a strip connector 120, as shown in FIG.

The sensor strip 110 is a sensor used for analyzing a sample such as blood or body fluids collected from a human or an animal. The sensor strip 110 is a sensor for detecting various types of living body such as blood glucose, blood cholesterol, blood hemoglobin, blood alcohol concentration, It is possible to output the sample signal corresponding to the information. In the present embodiment, the sensor strip 110 may measure blood glucose of the supplied specimen and output a specimen signal. Here, the sensor strip 110 may be a replacement consumable item for each sample measurement. Because of the manufacturing process of the sensor strip 110, each sensor strip 110 may have a different measurement error at the time of manufacture. That is, since the sensor strips 110 used by the user for blood glucose measurement may have different measurement errors from one sensor strip 110 to another, in order to accurately measure blood glucose, a measurement error corresponding to each sensor strip 110 It is necessary to perform correction in consideration of the above. Here, the sensor strip 110 according to an embodiment of the present invention includes a correction code corresponding to a measurement error of each sensor strip 110, and outputs a correction code signal corresponding to the measurement error at the time of outputting a sample signal Can be output together. Therefore, in the operation unit 200, accurate blood glucose information such as blood glucose level can be provided to the user by analyzing the sample signal in consideration of the measurement errors of the respective sensor strips 110.

2, the sensor strip 110 according to an exemplary embodiment of the present invention includes an insulating substrate 111, a working electrode portion 112, a reaction portion 113, and a code electrode portion 114 ).

The insulating substrate 111 is located on the bottom surface of the sensor strip 110 and can function as a body of the sensor strip 111. The insulating substrate 111 may be a glass or inorganic substrate, a plastic substrate, or a film. In some embodiments, a PET (polyethylene terephthalate) film, a polycarbonate film, or the like may be used.

The operation electrode unit 112 may be formed on the insulating substrate 111 and may apply an input operating voltage to induce an electrochemical reaction in the specimen. The working electrode unit 112 may be formed by applying a conductive material on the insulating substrate 111 and laser-patterning or masking the shape of the working electrode unit 112 with a laser. The working electrode 112 may include a working electrode 112a and a reference electrode 112b and may be spaced apart from the working electrode 112a by a predetermined distance. Here, the working electrode 112a can apply the input operating voltage to the reaction part 113, and the reference electrode 112b can maintain the reference voltage corresponding to the operating voltage. Therefore, an operating voltage may be applied between the working electrode 112a and the reference electrode 112b.

The reaction part 113 may be formed on the operation electrode part 112 and the sample to be measured may be placed on the reaction part 113. In particular, the reaction unit 113 may be formed on a region across the working electrode 112a and the reference electrode 112b of the working electrode unit 112, as shown in FIG. Accordingly, the reaction unit 113 can receive the operation voltage formed between the working electrode 112a and the reference electrode 112b, and the electrochemical reaction of the sample occurs on the reaction unit 113 . For example, a current corresponding to the blood glucose level of the sample may flow between the working electrode 112a and the reference electrode 112b by the applied operating voltage, and the working electrode unit 112 may supply the current as a sample signal Can be output. In other words, the operation electrode unit 112 can output the sample signal according to the electrochemical reaction in the specimen by applying the input operating voltage to the reaction unit 112. Here, the case of measuring the blood glucose level of a specimen is exemplified, but a similar method can be utilized in the case of measuring the amount of cholesterol, lactic acid concentration, blood alcohol concentration, etc. in the blood of the specimen.

Although not shown, the operation electrode unit 112 may further include a sample recognition electrode. That is, it is possible to determine whether the sample is introduced into the reaction part 113 using the sample recognition electrode. Therefore, it is possible to allow the measuring unit 100 to perform measurement such as blood glucose measurement on the specimen only when it is confirmed that the specimen has flowed into the reaction unit 113 after checking whether the specimen is introduced into the sample recognition electrode have.

The code electrode unit 114 can output a correction code signal corresponding to the electrode pattern P formed on the code electrode unit 114 by using the code detection voltage to be inputted. The code electrode portion 114 may be formed on the insulating substrate 111 and may not be overlapped with the working electrode portion 112. The code electrode part 114 may be formed by applying a conductive material on the insulating substrate 111 and laser patterning or masking the shape of the working electrode part 112 with a laser. The electrode pattern P may be formed in such a manner that an insulating tape or insulating ink is further adhered or applied onto the code electrode portion 114 after the cord electrode portion 114 is formed, can do.

3 and 4, the code electrode portion 114 may be connected to the code detection terminal 122 of the strip connector 120 and may be connected to the code detection terminal 122 A contact point connection may be formed. The plurality of code detecting terminals 122 included in the strip connector 200 can be distinguished according to the number or position of the contacts electrically connected to the code electrode portion 114. [ The code electrode portion 114 may form the contact combination in such a manner that the code electrode portion 114 includes an insulating surface in a region forming a contact point with the code detection terminal 122. The contact combination may include a measurement error of the sensor strip 110 .

5, when the sensor strip 110 is inserted into the strip connector 120, any one of the code detection terminals 122 of the strip connector 120 is supplied with the code detection voltage can do. In this case, current flows only through the code detection terminal 122 electrically connected to the code electrode portion 114 among the remaining code detection terminals 122b. Therefore, the code electrode portion 114 can output the correction code signal corresponding to the electrode pattern P by using the code detection voltage to be inputted.

For example, as shown in Fig. 6, the electrode pattern P can be formed on the code electrode portion 114 using insulating ink. Here, there are four code detection terminals 122, and a code detection voltage can be applied at the code detection terminal located at the left end of the four. Therefore, when there is no insulating surface on the code electrode portion 114, the current is output at all three code detection terminals, and this corresponds to the binary number 111. When an insulating surface is formed only in the second area, a current is outputted from the remaining two code detection terminals, and this corresponds to the binary number 011. [ Similarly, when the insulating surface is formed only in the third region, it corresponds to the binary number 101, and when the insulating region is formed only in the fourth region, it corresponds to the binary number 110. [ If an insulating surface is formed in the second and third regions, the binary number is 001, if the insulating surfaces are formed in the second and fourth regions, the binary number is 010, and if the insulating surfaces are formed in the third and fourth regions, Therefore, in the code electrode portion 114, it is possible to output the correction code signal by outputting a current at each code detection terminal connected according to the contact combination. However, in addition to the code detection terminal for applying the code detection voltage, at least one of the remaining three code detection terminals needs to be connected to the code electrode portion 114. That is, the embodiments forming the insulating surfaces for the second, third, and fourth regions may be excluded. On the other hand, as shown in Fig. 7, a correction code signal can also be generated in the same manner when a perforated insulating film is attached on the code electrode portion 114. [ Depending on the embodiment, the number of the code detecting terminals 122 may be four or more or less than four, and the content of the present invention is not limited by the number of the code detecting terminals 122. [

The strip connector 120 may include a connection portion to which the sensor strip 110 is mounted and may apply power such as an operating voltage and a code detection voltage to the sensor strip 110 through the connection portion. In addition, the strip connector 120 may receive the sample signal and the correction code signal corresponding to the operation voltage, the code detection voltage, and the like from the sensor strip 110, and then provide the sample signal and the correction code signal to the operation unit 200. The strip connector 120 may include a sample signal terminal portion 121 and a code detection terminal portion 122 as shown in Fig.

The sample signal terminal unit 121 can apply an operation voltage to the operation electrode unit 112 of the sensor strip 110 and receive a detection signal corresponding to the applied operation voltage from the operation electrode unit 112 . 3 and 4, the sample signal terminal unit 121 may be connected to the working electrode 112a and the reference electrode 112b of the working electrode unit 112, And may not be electrically connected to the electrode 114. As described above, when the sample signal terminal unit 121 applies the operating voltage to the working electrode 112a and the reference electrode 112b, the sample placed in the reaction unit 113 is subjected to electrochemical Reactions can occur. A sample signal as a result of the electrochemical reaction may be input to the sample signal terminal unit 121 through the working electrode 112a and the reference electrode 112b and the sample signal terminal unit 121 may transmit the sample signal (200).

The code detection terminal unit 122 can receive a correction code signal of the sensor strip 110 from the code electrode unit 114 by applying a code detection voltage to the code electrode unit 114 of the sensor strip 110. [ A plurality of code detecting terminals may be connected to the code electrode unit 114 on the code detecting terminal unit 122. The plurality of code detecting terminals may be connected to the code electrode unit 114 on the basis of the electrode pattern P formed on the code electrode unit 114, The set contact set can be formed. Therefore, when the code detection terminal unit 122 applies the code detection voltage, it is possible to receive, as the correction code signal, the current flowing into each of the code detection terminals connected according to the contact combination, Can be provided to the operation unit 200. Here, as shown in FIG. 6, the correction code signal can be distinguished according to the number or position of the contacts into which the current flows.

The operating voltage and the code detection voltage supplied from the power supply unit are supplied to the strip connector 120 from the power supply unit (not shown) included in the measuring apparatus. Lt; / RTI >

The operation unit 200 may perform a function of controlling the overall operation of the measurement apparatus and may receive a sample signal of the blood sugar of the sample and a correction code signal of the sensor strip 110 from the measurement unit 100. The operation unit 200 can derive a measurement error of the measurement unit 100 from the correction code signal and correct the received sample signal using the measurement error. Thereafter, biometric information such as the blood glucose level for the specimen can be calculated using the corrected specimen signal. For example, the operation unit 200 may include a table table in which a measurement error of the measurement unit 100 corresponding to each of the input correction code signals is recorded, A correction value or the like may be set in advance. Accordingly, the operation unit 200 can find the correction value corresponding to the correction code signal using the table, and can apply correction to the sample signal to correct the measurement error of each sensor strip 110 .

Additionally, a measurement error may occur in the sample signal measured by the measurement unit 100 depending on the ambient temperature. Accordingly, the operation unit 200 can receive the temperature signal for the ambient temperature from the temperature measurement unit 400, and can perform correction for the sample signal using the temperature signal. Here, the temperature measuring unit 400 can utilize anything that can measure the ambient temperature.

The calculating unit 200 can correct the sample signal using the correction code signal or the temperature signal, and then use the corrected sample signal to generate biometric information such as the blood sugar amount of the sample. Then, the operation unit 200 can display the generated biometric information to the user through the display unit 300. Therefore, the user can visually recognize the biometric information displayed on the display unit 300. In addition, the measuring apparatus according to an embodiment of the present invention may further include an alarm unit and the like, and may output an alarm sound or the like using the alarm unit when the measured biometric information such as the blood sugar amount is equal to or greater than a preset reference value.

Herein, the blood glucose measuring device is mainly described as an embodiment of the present invention, but the present invention is not limited to this, and can be applied to a measuring device such as a biosensor for measuring various kinds of biometric information. For example, in addition to blood glucose, there may be a measuring device for measuring blood cholesterol, blood hemoglobin, lactic acid concentration and the like. In this case, a sensor strip for outputting a sample signal for each sample may include a correction code signal corresponding to the sensor strip Can be output together. Here, the electrode pattern corresponding to the correction code included in the sensor strip has been described above, and thus a detailed description thereof will be omitted.

8 is a flowchart showing a measurement method according to an embodiment of the present invention.

8, the measurement method according to an embodiment of the present invention includes a correction code receiving step S100, a sample signal generating step S200, a sample signal correcting step S300, and a biometric information generating step S400 can do.

Hereinafter, a measurement method according to an embodiment of the present invention will be described with reference to FIG.

In the correction code receiving step (S100), the correction code signal for the sensor strip can be received from the electrode pattern formed on the sensor strip. When the sensor strip is inserted into the sensor strip, a code detection voltage may be applied to the sensor strip to receive a correction code signal corresponding to a measurement error of the sensor strip. The code electrode portion of the sensor strip may be included in the electrode pattern corresponding to the measurement error. When the code detection voltage is applied, the correction code signal may be input according to the electrode pattern. According to an embodiment, when the sensor strip is inserted and the correction code signal is input, it is also possible that the measurement device determines that the sensor strip is mounted.

In the sample signal generation step (S200), an operation voltage may be applied to the sensor strip to generate a sample signal for the sample supplied to the sensor strip. That is, an operating voltage may be applied to a specimen positioned on a sensor strip to induce an electrochemical reaction in the specimen, and the sensor strip may output a specimen signal corresponding to the electrochemical reaction. Here, the measuring device may apply an operating voltage to the working electrode portion of the sensor strip, and may receive the sample signal from the working electrode portion. Meanwhile, since the specimen signal generation step (S200) needs to be performed when the specimen is located on the sensor strip, the specimen recognition step may be further performed before the specimen signal generation step (S200). That is, it is possible to determine whether the sample is introduced using the sample recognition electrode included in the sensor strip or the like, and perform the sample signal generation step (S200).

In the sample signal correction step (S300), the measurement error of the sensor strip can be derived using the correction code signal, and the sample signal can be corrected by reflecting the measurement error. The correction code signal measured in the correction code receiving step (S100) may correspond to a measurement error reflected on the sensor strip in the manufacturing process of the sensor strip. Therefore, in the specimen signal correction step (S300), after deriving the correction value corresponding to the correction code signal, the specimen signal can be corrected by applying the correction value to the specimen signal. According to the embodiment, there may be a table table in which correction values corresponding to the respective correction code signals are recorded, and correction values corresponding to the respective correction code signals can be derived by referring to the table table. In addition, since the specimen signal may include an error according to the ambient temperature, the specimen signal correction step (S300) may further include a step of performing a temperature-dependent correction after measuring the ambient temperature.

In the biometric information generation step (S400), the biometric information for the specimen can be extracted using the corrected specimen signal. The measuring device can calculate various kinds of biometric information such as the blood glucose level of the test sample using the corrected test sample signal and then displays the calculated biometric information on the user visually or audibly through a display unit included in the measuring device can do.

Here, the blood glucose measurement method is described as an example of the present invention. However, the present invention is not limited to this and can be applied to a measurement method for measuring various kinds of biometric information.
