Description

[0001] The present invention relates to a strip for inspecting reaction,

Disclosure of the Invention The present disclosure relates to a reaction test strip and a reaction test apparatus using the same.

The term "reaction strip" refers to a kind of test paper used to determine the result of a predetermined chemical reaction. As an example, when a urine test is performed to detect a target antigen in the urine, the test strip may include a reagent comprising an antibody that reacts with the antigen. In addition, the reaction test strip can also easily identify whether the test person has a predetermined target antigen in the urine by expressing the result of the antigen-antibody reaction as a color change.

Brief Description of the Drawings Fig. 1 is a view schematically showing a conventional reaction test strip. Fig. 1 (a), the reaction test strip 10 includes a plurality of reaction sites 110, 120, 130, 140, and 150 having different antibody reagents on the body 105 . Thus, as shown in FIG. 1 (b), the color change observation of the plurality of reaction sites 110, 120, 130, 140, and 150 is performed only once by immersing in the container 170 containing the urine 160 The results of multiple antigen-antibody reactions can be confirmed.

In the case of the above-described conventional test strips, the test results can be easily confirmed even by the general public who does not have expert knowledge, by confirming the result of the antigen-antibody reaction through the color change of the reaction site. However, in the inspection industry, in which a large number of test strips are used to check the test results, the above-described method may be subject to various limitations. First, depending on the case, the color indicating the result of the antigen-antibody reaction may vary with time. That is, the antigen-antibody reaction may be contaminated or influenced by the surrounding environment over time and may exhibit undesirable color changes. Secondly, it is therefore necessary to observe the hue of the result of the antigen-antibody reaction within a limited time, which may be difficult to ascertain through manual inspection by the inspector.

The embodiment of the present disclosure provides a reaction inspection strip and an inspection apparatus therefor that can efficiently confirm a predetermined reaction inspection result within a limited time.

Disclosed is a reaction test strip according to one aspect of the present disclosure. The reaction test strip includes a body portion having a predetermined width, height, and length, a plurality of reaction portions arranged along a longitudinal direction of the body portion on one surface of the body portion, And a positional information marker disposed on a surface or inside of the body corresponding to the position of the reaction inspection part and providing position information of the reaction inspection part to the position reading device. The position information markers include at least one of an optical signal pattern, a physical structure pattern, an electric circuit pattern, and an image pattern.

A reaction test apparatus according to another aspect of the present disclosure is disclosed. Wherein the reaction test apparatus comprises a reaction test strip having a reaction test section and a positional information marker disposed at a position corresponding to a position of the reaction test section, a reaction test strip disposed adjacent to the reaction test strip, A position reading device for detecting the position information markers of the reaction test strip when moving in one direction, and a photographing device for photographing the reaction inspection part in synchronization with the timing at which the position reading device detects the position information markers . The position information markers include at least one of an optical signal pattern, a physical structure pattern, an electric circuit pattern, and an image pattern.

According to the present disclosure, the reaction test strip may include a positional information marker that provides positional information of a reaction inspection unit that provides the reaction result with the target material as color information. The image of the reaction inspection part can be easily photographed while moving the reaction inspection strip using the information of the position information markers.

Particularly, in the case of moving the reaction test strip through manual operation, the reaction test strip can be passed through the inspection apparatus with constant velocity or acceleration. In this way, even when the reaction inspection strip moves at a constant speed or acceleration, the image of the reaction inspection part can be acquired quickly by driving the photographing device in synchronization with the position information of the position information markers. The obtained image can be effectively provided to read whether or not the reaction result is within a limited time.

In some other embodiments, as the reaction test strip, the reaction test strips described above with reference to Figs. 3A, 4, 5, 6A, 7, 8, 9A, 10, (30, 32, 34, 40, 42, 44, 50, 60, 70) may be applied. Correspondingly, as the position reading apparatus, the position reading apparatuses 250, 350, 360, 440 and 550 described above with reference to Figs. 2B, 3B, 3C, 6B and 9D can be applied.

Referring again to FIG. 12, the photographing apparatus 260 may be disposed adjacent to the strip converging apparatus 240. The photographing apparatus 260 is configured to detect the positions of the reaction inspection units 220a, 220b, ..., 234l in synchronization with the timing at which the position reading apparatus 250 detects the position information markers 232a, 232b, ..., 232l, 234a, 234b, 220l.

The photographing apparatus 260 may include a light source 262 and a photodetector 264. The light source 262 may provide visible light or ultraviolet light to the strip converging device 240 to enable color discrimination of the reaction testing strip 20 moving on the strip converging device 242. [

The photodetector 264 may be disposed adjacent to the light source 262 and may include a color sensor. The photodetector 264 can acquire information necessary for implementing the images of the reaction inspection units 220a, 220b, ..., and 220l.

In some embodiments, the light source 262 may comprise a first polarizing filter polarized in a first direction and the photodetector 264 may comprise a second polarizing filter polarized in a direction perpendicular to the first direction . Thus, the light source 262 provides the light polarized in the first direction to the reaction inspecting units 220a, 220b, ..., and 220l, and the light detector 264 emits the light beams emitted from the reaction inspecting units 220a, 220b, ..., It is possible to collect the light polarized in the second direction out of the light.

The light polarized in the first direction may be scattered on the surfaces of the reaction inspectors 220a, 220b, ..., 220l after entering the reaction inspectors 220a, 220b, ..., 220l. At this time, the scattered light can be the light polarized in the first direction and can generate the gloss of the reaction inspection units 220a, 220b, ..., 220l. Generally, the gloss can act as an element that hinders the clear color determination of the reaction inspection sections 220a, 220b, ..., 220l. Therefore, the photodetector 264 can capture the clear color by suppressing the light that is polarized in the first direction, which is the incident light, and collecting the light polarized in the second direction.

In some embodiments, the polarization states of the light incident on the reaction inspectors 220a, 220b, ..., and 220l and the polarization states of the light emitted from the reaction detectors 220a, 220b, ..., and 220l and collected by the photodetector 264, To operate differently, a known beam splitter can be applied. At this time, the beam splitter can be disposed on the optical path between the light source 262 and the reaction inspection strip 20 and on the optical path between the reaction inspection strip 20 and the photodetector 264. The beam splitter may reflect only the light polarized in the first direction among the light incident from the light source 262 to the beam splitter and provide the reflected light to the reaction inspection units 220a, 220b, ..., and 220l. The beam splitter transmits the light polarized in the second direction out of the light again emitted from the reaction inspection units 220a, 220b, ..., 220l by the polarized light in the first direction, .

Figure 13 is a schematic representation of a reaction test apparatus using a reaction test strip according to another embodiment of the present disclosure; Referring to FIG. 13, the reaction testing apparatus 1300 may not include a separate position reading apparatus 250.

When the reaction inspection strip 80 moves in the direction M1 on the strip converging device 240, the photographing apparatus 260 uses the light source 262 and the photodetector 264 to control the reaction inspection section (not shown) on the body section 210 220a, 220b, ..., 220l can be read. Specifically, the photographing apparatus 260 can distinguish the images of the boundary regions of the reaction inspection sections 220a, 220b, ..., and 220l from the surface on the background image of the one surface of the body section 210. [ Therefore, the photographing apparatus 260 captures the moment when the reaction inspection strip 80 enters the boundary of the reaction inspecting sections 220a, 220b, ..., 220l from the background image of the one surface of the body section 210 during movement can do. At the same time, the photographing apparatus 260 can photograph images of the reaction inspecting sections 220a, 220b, ..., and 220l.

As described above, the image pattern formed by the interface between the body 210 and the reaction inspectors 220a, 220b, ..., 220l on one side of the body 210 can function as a positional information marker. In this manner, the photographing apparatus 260 can simultaneously perform the role of the position reading apparatus for reading the image pattern, and simultaneously transmit the photographing signal to the photodetector 264.

As described above, the inspection method using the reaction inspection apparatus can be diluted through the following steps. A reaction test strip and a positional information marker disposed at a position corresponding to the position of the reaction test strip. Next, a position reading device is disposed adjacent to the reaction inspection strip, and the reaction inspection strip is moved at a constant speed or acceleration in one direction, and the reaction inspection strip is allowed to move through the position reading device. Next, in synchronism with the timing at which the position information marker is detected by the position reading device, the reaction inspection part is photographed using the photographing device.
