Description

Technical Field

[0001] The present invention relates to the field of in vitro diagnostic test equipment, in particular to an in vitro diagnostic test equipment using a fluorescent marker. Background Art

[0002] In vitro diagnostics refers to products and services that obtain clinical diagnostic information by testing human samples (blood, body fluids, tissues, etc.) outside the human body, and then judge diseases or body functions. Fluorescent markers are one of the technologies for in vitro diagnostic testing. The diagnostic test device usually adds the sample to be tested into the sample addition area. After the sample reacts and mixes with other reagents pre-stored in the sample addition library, it flows through the sample reaction barrier, reaction chamber and time gate, arrives at the diagnostic unit for reaction, and finally flows into the used reagent library.

[0003] According to the patent document with the existing publication number CN117347339A, an in vitro diagnostic test device using fluorescent markers is disclosed, which includes a device body and a seal, wherein the device body is provided with a sample adding part, a diagnostic unit and a reagent reservoir; the sample adding part is connected to the reagent reservoir through the diagnostic unit; the seal is detachably connected to the device body, and the seal is used to be removed from the device body after the substance to be tested reacts with the corresponding biochemical substance and the tracer reagent, so that the external sensor can detect the signal generated by the diagnostic unit, the diagnostic unit includes a fluid channel, and the sample adding part is connected to the reagent reservoir through the fluid channel. When the technical solution is used, the seal can be removed to perform detection, so as to achieve detection without interference, thereby effectively improving the ability and reliability of detecting trace substances. With respect to the above technical solution, although the solution provides the ability of detection through the seal, the seal cannot be effectively supported during use, and tilts and shakes during use, resulting in ineffective sealing, which is inconvenient during use. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide an in vitro diagnostic test device using fluorescent markers to solve the problems raised in the above-mentioned background technology. The present invention has a novel structure. When in use, the sealing plate is fixed by forming three-point support between the limit groove, the limit plate and the arc seat. When in use, the arc seat slides horizontally to lay the sealing plate horizontally on the top of the connecting hole for sealing. Later, the arc seat can complete the support and extrusion limit of the sealing plate at the same time to ensure the sealing of the top of the connecting hole.

[0005] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical scheme: an in vitro diagnostic test device using fluorescent markers, comprising a diagnostic test device body, the diagnostic test device body comprising a box body, the top of the box body is provided with an opening, a cover plate is movably installed inside the opening, one end of the box body is provided with a fixing groove, the cover plate is movably installed inside the fixing groove, a movable seat and a fixed seat are respectively installed at the bottom of the box body, the fixed seat is fixedly installed at the bottom of the box body, a slide groove is provided on the side of the box body, and a slider is movably installed inside the slide groove.

[0006] Furthermore, a movable plate is fixed to one end of the sliding block, and a protrusion is fixed to the side of the movable plate.

[0010] Furthermore, a connecting hole is opened on the inner wall of the box body, a through hole is opened on the inner wall of the connecting hole, and a connecting groove is opened between the connecting holes.

[0011] Furthermore, a limiting plate is welded on the inner wall of the box body, a mounting hole is opened at the bottom of the box body, and a limiting hole is opened at one end of the mounting hole.

[0012] Furthermore, a limiting column is movably installed inside the installation hole and the limiting hole, and an extrusion plate is fixed to one end of the limiting column, and the extrusion plate cooperates with the limiting plate.

[0013] Furthermore, a support mechanism is fixed on the inner wall of the mounting hole, one end of the support mechanism is fixed on the extrusion plate, and the other end of the limiting column is fixed on the movable seat.

[0014] Furthermore, the arc seat is movably matched with the sealing plate, and the fixed block is movably installed inside the slide groove.

[0015] Beneficial effects of the present invention: The present invention is an in vitro diagnostic test device using fluorescent markers, comprising a box body; an opening; a cover plate; a movable seat; a fixed seat; a movable plate; a protrusion; a fixed box; an opening; a sealing plate; a slide groove; a slider; a connecting hole; a through hole; a connecting groove; a fixed block; an arc seat; a fixing groove; a limit groove; a limit plate; a mounting hole; a limit hole; a limit column; a support mechanism; and an extrusion plate.

[0016] 1. This is an in vitro diagnostic test device that uses fluorescent markers. When in use, the sealing plate is fixed by forming three-point support between the limit groove, the limit plate and the arc seat. When in use, the arc seat slides horizontally to lay the sealing plate horizontally on the top of the connecting hole for sealing. Later, the arc seat completes the support while allowing the sealing plate at one place to move back and forth. The back and forth movement of the sealing plate completes the extrusion and limitation of the sealing plate to ensure the sealing of the top of the connecting hole.

[0017] 2. This is an in vitro diagnostic test device that uses fluorescent markers. The cover plate blocks and seals the entire box when the device is not in use. When in use, one end of the sealing plate is limited inside the limiting groove. The limiting groove provides a support limiting point for the sealing plate. The subsequent movement of the cover plate allows the sealing plate to be quickly separated from the limiting groove, which makes it easy to quickly remove the sealing plate from the inside of the box.

[0018] 3. This is an in vitro diagnostic test device using fluorescent markers. One end of the sealing plate is placed between the extrusion plate and the limit plate. When the box is placed on the desktop, the movable seat is squeezed by the pressure of the box itself. The extrusion plate on the movable seat moves upward to complete the extrusion and fixation of one end of the sealing plate. In the later stage, the fixed seat and the movable seat are misaligned up and down. After the misalignment, the box as a whole is tilted to facilitate the flow of internal liquid.

[0027] In this embodiment, a movable plate 6 is fixed to one end of the slider 12, a protrusion 7 is fixed to the side of the movable plate 6, a fixed box 8 is fixedly installed inside the box body 1, an opening 9 is opened on the fixed box 8, a reagent reservoir is installed inside the fixed box 8, a sealing plate 10 is movably installed inside the box body 1, a limiting groove 19 is opened at one end of the cover plate 3, one end of the sealing plate 10 is movably installed inside the limiting groove 19, the through holes 14 are connected in a U-shape, one end of the U-shaped pipe is connected to the reagent reservoir, and when in use, the limiting plate 20 provides an upward limiting force for one end of the sealing plate 10 to avoid loosening caused by the upward tilting of the sealing plate 10.

[0028] In this embodiment, a fixing block 16 is fixed on the inner wall of the movable plate 6, an arc seat 17 is fixedly installed between the fixing blocks 16, a connecting hole 13 is opened on the inner wall of the box body 1, a through hole 14 is opened on the inner wall of the connecting hole 13, a connecting groove 15 is opened between the connecting holes 13, a limiting plate 20 is welded on the inner wall of the box body 1, a mounting hole 21 is opened at the bottom of the box body 1, a limiting hole 22 is opened at one end of the mounting hole 21, and the connecting groove 15 and the connecting hole 13 cooperate with each other to facilitate the flow of liquid inside the connecting holes 13 and the through holes 14 at different positions.

[0029] In this embodiment, a limiting column 23 is movably installed inside the mounting hole 21 and the limiting hole 22, and an extrusion plate 25 is fixed at one end of the limiting column 23, and the extrusion plate 25 cooperates with the limiting plate 20.
