Description

[0001] The present invention relates to a specimen containing unit, a specimen measuring cassette, a specimen measuring unit, and a specimen measuring apparatus.

The present invention relates to a specimen containing unit, a specimen measurement cassette, a specimen measurement unit and a specimen measurement apparatus, and more particularly to a specimen containing unit which can obtain accurate measurement results in measuring the result of a reaction between a specimen and a reagent, A measurement unit and a sample measurement apparatus.

BACKGROUND OF THE INVENTION [0002] In recent medical diagnostics or treatment areas through drugs, the measurement of concentrations of analytes to anesthetics or harmful chemicals has been usefully used in the medical or environmental field. Among them, the measurement of the biological sample concentration used in medical diagnostic and therapeutic fields continues to increase with the desire of human beings to be liberated from various diseases. Particularly, the glycosylated hemoglobin test, which can measure blood sugar in relation to diabetes, has an increasing interest because it can detect a relatively long-term average blood glucose level by one measurement.

Hemoglobin A1c (HbA1c), also referred to as glycated hemoglobin, is one of the hemoglobins contained in human Red Blood Cells. When blood sugar (glucose) in the blood rises, some of the glucose in the blood binds to the hemoglobin. Thus, the hemoglobin associated with glucose is called glycated hemoglobin. This glycated hemoglobin test can be used to estimate the mean value of blood glucose for the past 2 to 3 months. The glycated hemoglobin test has the advantage of being able to collect blood and examine it regardless of the meal time.

On the other hand, in the case of U.S. Patent No. 6,300,142, in order to measure an analyte present in a sample, a test sample is reacted with a first reactant through a first inlet and sequentially reacted with a second reactant through a second inlet, Is disclosed. In this case, measurements should occur sequentially at time intervals.

It is also necessary to intervene in the measurement step so that the measurer injects the test sample sequentially and reacts. Furthermore, since the beads combined with the glycated hemoglobin must be filtered once, the measurement is complicated and takes a long time.

That is, the rotation of the specimen containing unit 100 by the rotational force applying unit 310 may be applied to the principle of a flat screwdriver or a phillips screwdriver.

However, the rotation of the specimen containing unit 100 by the rotational force application unit 310 is not limited to being implemented by the principle of the driver, and may be variously changed according to the intention of the person skilled in the art.

When the reaction between the first reagent R1 and the specimen is completed after a predetermined time by the rotation of the specimen containing unit 100, the reactant of the first reagent R1 and the specimen can be introduced into the measuring unit S3 .

4, the reactant of the first reagent R1 and the sample is introduced into the measuring unit S3 by the movement of the first foil tab 220 sealing the bottom of the first receiving unit S1 And the movement of the first foil tab 220 may be realized by an external force application unit 320 (indicated by an arrow) provided in the sample measurement body 300.

Fig. 6 is a schematic perspective view showing a specimen containing unit according to the present invention, and Fig. 7 is a rear view for explaining the direction of a specimen containing unit provided in the specimen containing unit according to the present invention.

6 and 7, the specimen containing unit 100 is a kind of structure that can contain a specimen as a blood sample, for example, so that the specimen can be locked to the reagent and react with the reagent.

Here, the reagent may be the first reagent R1 stored in the first receiving portion S1 of the sample measurement cassette 200 as described with reference to Figs.

Specifically, the specimen containing unit 100 includes a body portion 120 rotatable by an external force, an extension portion 130 formed by extending a predetermined length along a longitudinal direction from one surface of the body portion 120, And a sample containing part 140 provided at an end of the sample part 130 and having a containing hole 110 formed to penetrate the specimen by the capillary phenomenon.

The body portion 110 may have a substantially cylindrical shape and may have a groove 122 formed on the other surface thereof so that the rotational force applying portion 310 of the specimen measuring body 300 is inserted. The rotation of the part 120 can be applied to the principle of the driver.

The extension part 130 is a component that is rotatable in conjunction with the rotation of the body part 120 by the rotation force application part 310. The extension part 130 may be disposed on the outer side with respect to the center of one surface of the body part 120 have.

This is for stirring the specimen contained in the containing hole 110 and the first reagent R1 when the specimen containing part 140 is rotated by the rotation of the body part 120. [

In other words, the sample containing section 140 containing the sample is immersed in the first reagent R1 stored in the first storage section S1 of the sample measurement cassette 200, and the sample and the first reagent R1, the rotation of the body 120 is interlocked with the rotation of the body 120 to minimize the reaction time due to rotation.

Here, in order to maximize the efficiency of the reaction in the process of rotating the body-containing part 120 in conjunction with the rotation of the body part 120 while the first reagent Rl is locked, the direction of the containing hole 110 is the length Direction and a predetermined angle can be maintained.

Specifically, the direction of the containing hole 110 is formed by a virtual circle C formed by the end of the extension part 130 when the body part 120 is rotated by the rotation of the extension part 130 And the direction corresponding to the tangential direction (D), whereby the sample contained in the containing hole (110) can be efficiently introduced into the first reagent (R1).

As a result, the blood sample contained in the containing hole 110 of the sample containing section 140 is effectively hemolyzed by the first reagent R1 due to the direction of the containing hole 110 and the forming position of the extending section 130 You can escape.

The lower end of the specimen containing section 140 is inserted through the cover call section 210 covering the upper surface of the first accommodating section S1 of the specimen measuring cassette 200, The first reagent R1 may be sharply formed such that the sample is immersed.

Therefore, the specimen containing unit 100 according to an embodiment of the present invention can stably penetrate the first receiving portion S1 in which the first reagent R1 is stored while containing the specimen in the containing hole 110 .

However, the entire lower end of the specimen-containing portion 140 need not be formed sharply, and at least a part of the specimen-containing portion 140 may be sharply formed.

8 is a schematic perspective view showing a modification of the specimen containing unit according to the embodiment of the present invention.

Referring to FIG. 8, the specimen containing unit 100 'may have a width corresponding to the width of the extension 130' and the specimen containing unit 140 ', or may be integrally formed.

As a result, the extension 130 'and the sample containing portion 140' may be physically identical components, and the lower end of the sample containing portion 140 'may be sharply formed.

Fig. 9 is a schematic cutaway perspective view showing a sample measurement unit according to the present invention. Fig.

9, the sample measurement cassette 200 may constitute a sample measurement unit 400 together with the sample containing unit 100 described with reference to FIGS. 1 to 8, and may include a first storage unit S1, A second accommodating portion S2 and a measuring portion S3.

The first receiving part S1 can accommodate the first reagent R1 and the space in which the sample contained in the containing hole 110 of the sample containing part 140 reacts with the first reagent R1 .

That is, the first accommodating portion S1 penetrates the specimen accommodating portion 140 into the first accommodating portion S1 and rotates the specimen accommodating portion 140 by the rotative force providing portion 310, May mean the space in which the first reagent (R1) reacts.

However, the introduction of the sample into the first accommodating portion S1 is not limited to the one embodied by the sample containing portion 140, and may be implemented by various methods.

The first reagent R1 may be a blood sample for hemolysis of a blood sample that is a specimen, and a glycated hemoglobin binding material-bead that selectively reacts with a glycated hemoglobin.

The blood can be, for example, a buffer solution containing a surfactant such as N-2-Hydroxyethylpiperazine-N'-2-ethanesulfonic Acid HEPES (pH 8.1). Hemolyzed blood samples are accompanied by hemoglobin and glycated hemoglobin.

The glycated hemoglobin-binding substance is a substance capable of specifically binding to glycated hemoglobin. For example, at least one of boronic acid (BA), concanavalin A (Lectin), and antibody.

The bead may be a polymeric polysaccharide support such as agarose, cellulose or sepharose, polystyrene, polymethylmethacrylate, polyvinyltolune, and the like. At least one of latex beads and glass beads.

At this time, the size of the glycated hemoglobin binding material-bead size is preferably selected in consideration of the reaction time with the glycated hemoglobin-binding substance-bead precipitation time and the glycated hemoglobin bound to the glycated hemoglobin after the reaction.

In brief, the first reagent R1 may include blood for hemolysis of a blood sample that is a specimen, and a glycated hemoglobin binding material-bead that selectively reacts with glycated hemoglobin, and the blood, which is a specimen reacted with the first reagent (R1) It is preferable to measure the amount of total hemoglobin from the sample.

The second accommodating portion S2 may be partitioned from the first accommodating portion S1 and accommodate the second reagent R2.

The second reagent (R2) may include a washing solution capable of washing the mixture of the first reagent (R1) and a blood sample as a specimen.

Hemoglobin (Hb) present in the red blood cells of a blood sample as a specimen is mostly non-glycosylated hemoglobin (Ao). Only 4 to 14% of normal hemoglobin reacts with glucose to be present as glycated hemoglobin (HbA1c) .

Therefore, the glycated hemoglobin binding material-beads reacted with the blood sample through the first reagent R1 include glycated hemoglobin as well as general hemoglobin. Therefore, in order to measure the glycated hemoglobin in the blood, it is necessary to remove the normal hemoglobin.

For this, the second reagent (R2) preferably includes a washing solution capable of washing normal hemoglobin to enable measurement of glycated hemoglobin.

The measurement unit S3 may measure the result of the reaction between the first reagent R1 and the blood sample as the specimen and may measure the result of the reaction between the first accommodation unit S1 and the second accommodation unit S2 .

The measuring unit S3 may allow the mixture of the first reagent R1 and the blood sample, which is a specimen that is first introduced from the first containing unit S1, to flow into the blood sample and measure the total amount of hemoglobin in the blood sample , And the amount of hemoglobin can be measured using a light reflection characteristic by a measurement sensor (not shown) of the sample measurement body 300 on which the sample measurement cassette 200 is mounted.

Here, the measuring unit S3 may include an optical window that reflects light through an external optical sensor, which is a measurement sensor, and the cross section in the horizontal direction toward the lower side may be reduced.

Specifically, the measuring unit S3 may include a sloped surface 250 directed downward toward the center. The influx of the mixture of the first reagent R1 and the specimen into the measuring unit S3 may be adjusted by self weight Can be implemented.

As a result, the flow of the first reagent R1 into the measuring section S3 can be realized by the own weight of the first reagent R1.

Here, the outflow of the mixture of the first reagent (R1) and the specimen from the first receiving portion (S2) is performed by changing the position of the first foil tab (220) sealing the bottom of the first receiving portion And the positional change of the first foil tab 220 may be implemented by the external force application unit 320 of the sample measurement body 300.

On the other hand, after the total hemoglobin amount is measured for the mixture of the first reagent (R1) and the specimen introduced into the measurement unit (S3), the remaining solutions except for the binding material-bead bound to the hemoglobin and the glycated hemoglobin, And can be absorbed by the absorption portion 230 disposed below the measurement portion S3.

The absorber 230 may be, for example, an absorbent pad, but is not limited thereto.

After the remaining solution excluding the binding material-bead bound to the hemoglobin and the glycosylated hemoglobin is absorbed by the absorption part 230, the second reagent R2 is supplied from the second accommodation part S2 to the measurement part S3 And the second reagent R2 may be used to measure the amount of glycated hemoglobin by washing the blood sample mixture in the measuring unit S3.

Here, the outflow of the second reagent R2 from the second containing portion S2 to the measuring portion S3 is performed by the position of the second foil tab 240 sealing the bottom of the second containing portion S2 And the change of the position of the second foil tab 240 may be realized by the external force application unit 320 of the sample measurement body 300. [

On the other hand, the amount of the glycated hemoglobin is measured by a measurement sensor (not shown) of the sample measurement body 300, as in the case of measuring the amount of total hemoglobin from the blood sample mixture reacted with the first reagent Rl Can be measured.

Thereafter, the amount of hemoglobin can be divided by the amount of glycated hemoglobin to determine the relative amount of glycated hemoglobin in the blood sample as a sample (ratio of glycated hemoglobin (%) = glycated hemoglobin / total hemoglobin × 100).

Meanwhile, the reaction space between the sample and the first reagent (R1) and the second reagent (R2) may be different as described above. Specifically, the reaction space between the sample and the first reagent (R1) (S1), and the reaction space between the sample and the second reagent (R2) may be the measuring unit (S3).

The measuring unit S3 may be configured to receive the sample reacted with the first reagent R1 in the first receiving unit S1, that is, a mixture of the sample and the first reagent R1 The second reagent R2 may be received after a predetermined time elapses.

The change of the position of the first foil tab 220 and the second foil tab 240 sealing the bottoms of the first accommodating portion S1 and the second accommodating portion S2 may be performed by changing the position of the specimen measuring body 300, The external force application unit 310 may be implemented by an external force applying unit 310. [

In other words, the first reagent R1 and the second reagent R2 can be blocked from flowing out by the first foil tab 220 and the second foil tab 240, The first foil tab 220 and the second foil tab 240 are connected to the first receiving portion S1 and the second receiving portion S2 by the sample measurement main body 300 of the sample measurement apparatus 10 on which the measurement cassette 200 is mounted. The position of the second receptacle S2 from the bottom may be changed so that the first reagent R1 and the second reagent R2 may be introduced into the measurement unit S3.

Here, the external force applying unit 3200 provided in the specimen measuring body 300 may apply an external force to the opposite ends of the first and second foil tabs 220 and 240, Specifically, the external force application unit 320 may apply an external force to one end of the first foil tab 220 and provide an external force to the first end of the second foil tab 240.

However, the external force applying unit 320 may be formed to provide external force to the first foil tab 220 and the second foil tab 240. In this case, the first foil tab 220 And an external force which is pulled to one side of the second foil tab 240. [

Meanwhile, external force application by the external force application unit 320 may be implemented automatically or manually.
