Description

All-in-one joint inspection card

Technical Field

The utility model relates to the technical field of medical inspection, in particular to an all-in-one joint inspection card.

Background

Colloidal gold detection is a common labeling technology, is a novel immune labeling technology which uses colloidal gold as a tracer marker to be applied to antigen and antibody, and is widely used in various biological researches. When the label is heavily aggregated at the ligand, a red spot is visible to the naked eye and is thus used in a qualitative or semi-quantitative rapid immunoassay method.

The current detection card, for example 201910781484.0 discloses a colloidal gold detection card, a shell and a test strip arranged in the shell, wherein the shell comprises an upper shell and a lower shell, a sample adding hole and an observation window are arranged on the upper shell, and a fixing position for fixing the test strip is arranged on the lower shell. The detection card has only one sample adding hole and one observation window, which means that only one index can be detected at a time by using the existing detection card. To test multiple items, multiple test cards are required. The detection card is arranged, and only one index can be detected at a time. If multiple items are to be detected, the detection card is inconvenient to store, and the cost is high and resources are wasted.

Examples:

the multi-in-one joint inspection card shown in fig. 1-5 comprises a shell and a test strip 3, wherein the shell consists of an upper shell 2 and a lower shell 1, and the upper shell 2 and the lower shell 1 are formed by integrally injection molding plastic. The test strip 3 is disposed in a cavity between the upper case 2 and the lower case 1.

The device aims to provide a multi-in-one joint inspection card capable of inspecting multiple items at one time, so that the number of the test strips 3 is at least two, and the test strips can detect different indexes. The upper housing 2 is provided with a loading hole 5 and an observation window 6, the number of the loading holes 5 is at least one, and the number of the observation windows 6 is the same as that of the test strips 3. In this embodiment, four test strips 3, four observation windows 6 and one sample application hole 5 are used. A plurality of test strips 3 are placed in the housing in sequence, and the number of the sample adding holes 5 can be one as long as the sample can reach the sample pad 301 of each test strip 3 after being dropped from the sample adding holes 5.

In order to ensure that a sample can reach the sample pad 13 of each test strip 3 through one sample adding hole 5, adjacent sample pads 13 are connected through connecting pads, and the materials of the connecting pads are the same as those of the sample pads 13 so as to ensure the diffusion quality. In order to prevent interference from affecting the experimental results, other portions of the adjacent test strips 3 are not in contact.

The lower shell 1 is internally provided with separating strips 11 for forming clamping grooves, the number of the separating strips 11 is one less than that of the pairs of test strips 3, so that the number of the separated clamping grooves is the same as that of the test strips 3, and the positions of the clamping grooves correspond to the positions of the observation windows 6, so that operators can see the color development of the test strips 3 through the observation windows 6. The separation strip 11 divides the lower housing 1 into clamping grooves with the same width, and the width of the clamping grooves is the same as that of the test strip 3, so that the test strip 3 is limited in the housing and the detection results are prevented from being influenced mutually.

The test strips 3 used in this embodiment are colloidal gold test strips. The colloidal gold method is convenient and quick, is specific and sensitive, has strong stability and visual result judgment, and is suitable for vast basic-level inspectors, large-scale detection and large-area general investigation. The colloidal gold test strip 3 comprises a sample pad 13, a gold pad 14, an NC film 15, a water absorbing pad 16 and a back lining, wherein the sample pad 13, the gold pad 14, the NC film 15 and the water absorbing pad 16 are arranged on the back lining. The colloidal gold in the gold pad 14 is a gold-particulate non-radioactive tracer suspended in an aqueous solution in a colloidal state with a particle size of less than the micron order. After one end of the dried NC film 15 (sample pad 13) is immersed in the sample, the sample moves forward along the NC film 15 due to capillary action, and when moving to the area where the antibody is immobilized, the corresponding antigen in the sample specifically binds to the antibody, and the colloidal gold can make the area display a certain color.

The device can change the detection type of the test strip 3 according to different detection items. The upper housing 2 and the lower housing 1 are thus detachably connected, which may be a snap fit. The upper shell 2 and the lower shell 1 are respectively provided with a sliding groove 8 and a sliding block 9 which are matched with each other, a clamping groove 10 and a buckle 4. In this embodiment, the sliding grooves 8 are formed on two side walls of the upper housing 2 along the length direction, the sliding blocks 9 are formed on two side walls of the cavity of the lower housing 1, the sliding blocks 9 on two sides of the lower housing 1 are clamped in the sliding grooves 8 on two sides of the upper housing 2, and the upper housing 2 is pushed to enable the buckle 4 on the upper housing 2 to be clamped in the clamping groove 10 of the lower housing 1.

The shell is also provided with an anti-slip pushing piece, the pushing piece comprises a pushing block 7 and a pushing groove 12, the upper shell 2 is provided with the pushing block 7, and the surface of the pushing block 7 is provided with anti-slip patterns; the lower shell 1 is provided with a pushing groove 12. The push-pull type shell can be opened by inconvenient operating personnel due to surface slipping, and when the device is used, the upper shell and the lower shell can be respectively held by two hands of the operating personnel, thumbs of the two hands respectively prop against the pushing block 7 and the pushing groove 12 and exert force outwards, the upper shell 2 and the lower shell 1 can be separated, and the internal test strip 3 can be replaced.

It should be understood that the foregoing examples of the present utility model are merely illustrative of the present utility model and not limiting of the embodiments of the present utility model, and that various other changes and modifications can be made by those skilled in the art based on the above description, and it is not intended to be exhaustive of all the embodiments of the present utility model, and all obvious changes and modifications that come within the scope of the utility model are defined by the following claims.
