In the prior art, after the test core is inserted into the detector body, since the liquid needs to be dripped onto the test paper of the test core, the outer shell of the test core may also be dripped with liquid. At this time, the outer shell of the test core is The liquid may flow along the test core casing, and then flow into the interior of the detector body through the gap at the test core insertion port of the detector body, which will undoubtedly contaminate the inside of the detector body, and the inside of the detector body is contaminated by liquid. Affect its service life.

In order to avoid contamination of the inside of the detector body during the detection process, the present invention provides a test strip based detection device.

As shown in FIG. 1, a test strip-based detecting device may include:

a test core 110 carrying a test strip 100, and a detector body 120 provided with a cavity for carrying the test core 110;

Wherein, the first position is that the test core 110 is inserted into the detector body 120 and the test core Insert the opposite position of the port.

It should be noted that the sealing jaw 111 can be directly inserted into the testing core 110 to be fixed, so that the production operation process is relatively simple; and since the shape of the testing core in the prior art is compatible with the shape of the detector body Therefore, in order to ensure good sealing, the shape of the sealing jaw 111 is adapted to the shape of the test core 110 so that the sealing jaw 111 can smoothly pass through the test core 110 and be fixed at the first position. Wherein, the first position is a position opposite to the test core insertion port after the test core 110 is inserted into the detector body 120, so the sealing jaw 111 disposed at the first position can seal the test core 110 The test core is inserted into the gap at the port after insertion into the detector body 120.

It should be noted that, in practical applications, the sealing jaw 111 may be adhered to the first position of the outer casing of the testing core 110; or, the first position of the outer casing of the testing core 110 is provided with a groove, corresponding The sealing jaw 111 is fixed in the groove. Of course, after the sealing jaw 111 is fixed in the groove, it should protrude with respect to the outer casing of the test core 110 to ensure that the gap can be sealed. It will be understood by those skilled in the art that the above-described fixing manner is merely an example and should not be construed as limiting the invention.

The material selected for the sealing jaw 111 may be: rubber or engineering plastic, of course, not limited thereto. For example, the material of the sealing jaw 111 may be other materials that can prevent the flow of liquid.

In the test strip-based detecting device provided by the embodiment of the present invention, the first position on the outer casing of the test core is provided with a slit at the test core insertion port of the tester body after the test core is inserted into the detector body. Therefore, during the detection process, when the liquid on the outer shell of the test core flows along the outer shell of the test core, the liquid will not pass through the test core insertion port of the detector body under the barrier of the sealing jaw. The gap flows into the interior of the detector body, thereby effectively avoiding the problem of liquid contamination inside the detector body during the detection process. Since when the test core is inserted into the detector body, it is usually necessary to drip the liquid onto the test paper in the test core, and the liquid may splash on the outer casing of the detector body, and this will also cause the detector body to be exposed to the liquid. Pollution. Therefore, in order to solve the above problems, the embodiment of the present invention further provides a test apparatus based on a test strip.

Wherein, the first position is a position opposite to the test core insertion port after the test core 210 is inserted into the detector body 220, so the sealing jaw 211 disposed at the first position can seal the test core 210 The test core is inserted into the gap at the port after insertion into the detector body 220. Since the second position is a position between the first position and the test strip insertion port of the test core 210, the protective cover 212 disposed at the second position does not affect the insertion of the test core 210 into the detection. In the cavity of the instrument body 220. It should be noted that the protective cover 212 can also be disposed at the test strip insertion port of the test core 210 or the first position where the sealing jaw 211 is located; meanwhile, the protective cover 212 can be configured to accommodate the detector body.

It will be understood by those skilled in the art that the above-described fixing manner is merely an example and should not be construed as limiting the scope of the invention.

Further, when the liquid is dripped onto the test paper, when the test paper-based detecting device is placed on a test table or the like to wait for the detection result, in order to prevent the liquid from dripping onto the carrying table, the protective cover 212 The cross-sectional area of the two ends may be greater than the cross-sectional area of the first end such that the boot 212 can be flipped to accommodate the test core 210. For example, the protective cover 212 shown in FIG. 2 is funnel-shaped. When the test core 210 is inserted into the detector body 220, the protective cover 212 can accommodate a part of the detector body 220, as shown in FIG. 3; When the test strip-based detecting device is placed on a test table or the like to wait for the detection result, in order to prevent liquid from dripping onto the stage, as shown in FIG. 4, the protective cover 212 may be inverted to accommodate the test core 210, Thereby preventing liquid from dripping onto the stage.

The material selected for the sealing jaw 111 may be: rubber or engineering plastic, of course, not limited thereto. For example, the material of the sealing jaw 111 may be other materials that can prevent the flow of liquid. Correspondingly, the material of the protective cover 212 can be selected from rubber, engineering plastic or polyethylene, and is of course not limited thereto. It can be understood that the protective cover 212 can select a material having a certain degree of softness, so that when the test core 210 is idle, the protective cover 212 can be retracted to avoid occupying space, and in use, the protection is used. The cover 212 is unfolded, and at the same time, it is ensured that the protective cover 212 is easily turned over.

It can be understood by those skilled in the art that in the test strip-based detecting device, the test case 210 of the test core 210 may further be provided with a test window 213 for displaying the test strip test area and for fixing it to the detector body 220. a first locking element in the cavity (not shown in Figure 2); and the detector The body 220 may further include: a judging circuit (not shown in FIG. 2) for deriving the detection result according to the color displayed in the test strip test area of the test window 213, a display window 221 displaying the detection result, and the inner wall of the cavity A second locking element adapted to the first locking element, a release element 222 disposed on the housing for releasing the test core 210 secured within the cavity, and the like.

By using the test strip-based detecting device provided by the present invention, during the detecting process, when the liquid dripping onto the outer shell of the test core flows along the outer shell of the test core, the liquid will not pass the detector under the barrier of the sealing jaw. The gap of the test core insertion port of the body flows into the interior of the detector body, thereby effectively avoiding the problem of liquid contamination inside the detector body during the detection process; and, by protecting the detector body by the protective cover, the liquid can be avoided The liquid splashes onto the detector body when it is dripped onto the test strip in the test core. It can be seen that by using this scheme, the pollution problem of the inside and the outside of the detector body during the liquid detection process can be effectively avoided. In order to effectively avoid contamination of the inside and outside of the detector body during liquid detection, the present invention also provides a test apparatus based on a test paper.
