Description

Technical Field

[0001] The utility model belongs to the technical field of reagent kits, and in particular relates to a microfluidic analysis reagent kit. Background Art

[0002] Microfluidic analysis kit is a chemical kit for sample processing, mixing, separation and detection on a microfluidic chip. During the detection process, the reagents to be detected are difficult to mix, resulting in a slow reaction speed, which is inconvenient for the detector to observe and reduces the detection efficiency. In traditional experiments, if comparative experiments or synchronous experiments are required, multiple kits are often required to complete. These kits are usually independent units, and their internal structure and capacity cannot be flexibly adjusted. Therefore, in order to ensure the comparability or synchronization of the experiment, the experimenter has to operate multiple kits at the same time, which not only increases the complexity of the operation, but also easily introduces experimental errors. Since the existing microfluidic analysis kits are usually independent units, there is a lack of connection structure between the kits, so multiple kits cannot be effectively connected during transportation, which increases the complexity and cost of transportation. Especially in large-scale sample analysis and experiments, multiple kits need to be processed simultaneously, but because they cannot be connected, they can only be transported separately, resulting in low transportation efficiency and increased transportation time and cost.

[0003] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.

[0013] Preferably, the inner diameters of several of the placement holes are larger than the outer diameter of the reagent tube, thereby preventing the reagent tube from being stuck or clogged in the holes and reducing resistance and difficulty during operation.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] (1) In the present invention, the first spring, the damper, the second spring and the vibration motor are arranged to cooperate. The vibration motor causes the reagents in the inner shell to be shaken, which helps to evenly mix the reagents, thereby promoting the interaction between the reaction substances. This can improve the reaction efficiency, accelerate the reaction speed, shorten the time required for the experiment, and at the same time weaken the vibration caused by the bumps during transportation, reducing the possibility of damage to the reagents due to vibration.

The experimenter can change the position and quantity of the reagent partition at any time according to the experimental design and requirements to meet different experimental needs. By separating different reagents through the partition plate, the flexibility and practicality of the reagent kit can be effectively improved to ensure the reliability and accuracy of the experiment.

[0017] (3) In the present invention, by arranging the slide bar, the slide groove, the connecting plate, the limit hole and the limit bolt, multiple test kits can be assembled and combined into one whole for transportation. This reduces the time and effort of transporting each test kit separately, improves the transportation efficiency and shortens the transportation time. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In this embodiment, two groups of slide bars 14 are provided at the bottom end of the shell 1, and two groups of slide grooves 15 compatible with the slide bars 14 are opened on the top surface of the shell 1. A connecting plate 16 is provided at one end of the two groups of slide bars 14. Limiting holes 17 are provided on the two groups of connecting plates 16 and on one side of the shell 1 below the slide groove 15.

[0029] In addition, in this embodiment, two groups of placement plates 19 are provided in the inner shell 3, and a plurality of placement holes 20 are opened on the two groups of placement plates 19. The placement plates 19 with a plurality of placement holes 20 can be adjusted and customized according to actual needs. Users can freely choose the position and number of the placement holes 20 according to the size and number of reagent tubes to meet the needs of different experiments, thereby improving the flexibility and customizability of the inner shell 3.

[0030] Secondly, in this embodiment, a through groove 21 is opened on one side of the shell 1, and a slide plate 22 is slidably provided in the through groove 21. The slide plate 22 can be used to close the top of the shell 1, effectively protecting the reagent tubes or other items placed inside from pollution or damage from the external environment, such as dust, debris or accidental collision, etc., to ensure the safety and stability of the internal items.

The arc-shaped limit plate 23 can effectively fix the reagent tube placed in the placement hole 20, and the rubber pad 24 can provide a good buffering effect. The slide bars 14 at both ends of the two groups of outer shells 1 are slidably installed in the slide groove 15, and the limit bolts 18 are screwed into the limit holes 17, which is convenient for assembling multiple test kits, and multiple test kits can be combined into a whole for transportation.
