Abstract
Description
Technical Field
[0001] The utility model mainly relates to the technical field of detection kits, in particular to a limit detection kit. Background Art
[0002] The Plasmodium Universal Fluorescent PCR Detection Kit is a molecular biology detection tool used to quickly and accurately detect and identify Plasmodium, the pathogen of malaria. This kit is based on polymerase chain reaction technology and combines fluorescent labeling technology. The use of the Plasmodium Universal Fluorescent PCR Detection Kit is of great significance for the early diagnosis, timely treatment and epidemic control of malaria. Under the premise of complying with relevant regulations and standards, this kit is widely used in disease prevention and control centers, hospitals, research institutions and inspection and quarantine departments.
[0003] Before the fluorescent PCR detection kit is transported from the manufacturer to the laboratory, the reagent tube needs to be placed on the porous bracket inside the kit, that is, the reagent tube is located in the circular hole of the porous bracket. The current design of the porous bracket takes into account the convenience of removing and placing the reagent tube. These circular holes are generally larger than the cross-sectional diameter of the reagent tube. Therefore, during transportation, the reagent tube will oscillate on the porous bracket. During the oscillation process, if the seal of the reagent tube is poor or the sealing tape is not firm, sometimes liquid may leak out of the tube, resulting in the loss of reagent or contamination of other components in the kit, and sometimes it may cause the reagent tube to rupture or damage.

[0019] It should be noted that when an element is referred to as being "fixed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.
[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly associated with those skilled in the art in the technical field to which the present invention pertains. The terminology used herein in the specification of the present invention is for the purpose of describing specific embodiments and is not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0021] Please refer to the attached Figure 1-3 , a limit detection kit comprises a kit body 1, the kit body 1 comprises a box body 11, a porous bracket 12 is arranged in the box body 11, a reagent tube body 13 is arranged in the circular hole on the porous bracket 12, a box cover assembly 2 is arranged on the box body 11, the box cover assembly 2 comprises a cover body 21 and a pressing plate 22, a threaded hole 211 is provided on the cover body 21, a knob 23 is connected to the threaded hole 211, the lower end of the knob 23 is rotatably connected to the pressing plate 22, a plurality of mounting holes 221 are linearly arranged at equal intervals on the pressing plate 22, and an elastic limiting ring 24 is provided in each mounting hole 221, and the elastic limiting ring 24 is pressed on the upper edge of the reagent tube body 13.
[0022] Through the above structure, the reagent tubes can be effectively limited and constrained during transportation to prevent them from vibrating during transportation, and to avoid liquid leakage, reagent loss or contamination of the reagent kit due to poor sealing of the reagent tubes or loose sealing tape. At the same time, the reagent tube body itself is protected to prevent vibration and breakage, and the structure for limiting the reagent tube is designed on the cover body 21, so that after the cover is opened, the limitation of the reagent tube is cancelled without affecting the normal taking of the reagent tube. It is very convenient to use and has certain practical value.
[0023] The specific operation is as follows: first, place the reagent tube body 13 to be boxed into the porous bracket 12, and then cover the cover 21. At the same time, the pad 26 on the top block 25 just contacts the upper end of the reagent tube body 13. Then twist the knob 23, and the pressure plate 22 moves down, so that the elastic limiting ring 24 is pressed one by one on the upper edge position of the corresponding reagent tube body 13 to prevent the reagent tube body 13 from oscillating horizontally. After transporting to the destination, twist the knob 23 in the opposite direction, and the pressure plate 22 moves up, so that the elastic limiting ring 24 is separated from the upper end of the reagent tube body 13. At the same time, under the constraint of the pad 26, the reagent tube body 13 will not move up with the elastic limiting ring 24. Then the cover 21 can be opened and the reagent tube body 13 can be taken out.
[0024] Please refer to the attached Figure 1 and attached Figure 2 The force-applying part on the upper side of the knob 23 is located on the upper surface of the cover body 21. By turning the knob 23, the pressure plate 22 is driven to move up and down. The four top corners of the lower surface of the porous bracket 12 are provided with columns 14, and the lower end of each of the columns 14 is connected to the bottom of the inner wall of the box body 11. The porous bracket 12 is supported by the columns 14, so that the reagent tube body 13 will not collide with the bottom of the box body 11 after being placed on the porous bracket 12.
[0025] Please refer to the attached Figure 1 and attached Figure 3 A plurality of top blocks 25 are linearly arranged at equal intervals on the inner wall of the cover body 21, and a pad 26 is provided on each of the top blocks 25, and each pad 26 corresponds to the reagent tube body 13 one by one and abuts against the upper end of the reagent tube body 13. Through the mutual cooperation between the top blocks 25 and the pads 26, the upper end of the reagent tube body 13 is limited when the cover is closed. When the cover is opened, the auxiliary elastic limiting ring 24 is separated from the reagent tube body 13. Guide rods 27 are provided at the four top corners of the inner wall of the cover body 21, and the four guide rods 27 are slidably connected to the pressure plate 22. The guide rods 27 limit the pressure plate 22, so that the pressure plate 22 can move up and down stably.
[0026] The above description of the present invention is illustrative in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
