Description

Technical Field

[0001] The utility model relates to the technical field of medical diagnosis, in particular to a gene sequencing kit structure. Background Art

[0002] Gene sequencing kits are for the medical diagnostic industry. They optimize the structure of genetic reagents and use injection molding and heat sealing to create multi-cavity kits with excellent sealing properties. The common kit structure designs on the market only focus on usability, but have problems with actual manufacturing, cannot produce qualified samples, and lack mass production. The original kit structure design appears to have application functions, but there are problems during actual injection molding and heat sealing.

[0003] The test kit has a poor structure. During injection molding, it is easy to have serious glue shortage or perforation of the side wall of the cavity. After filling with liquid, the liquid in cavity No. 1 and cavity No. 2 are mixed. During laser welding, the local ribs of the box body are not firmly welded to the cover. After the box body is filled with liquid, the liquid is mixed. During injection molding, the mold core is very easy to break, and molding is very difficult. It is almost impossible to deliver qualified samples. When the gene test kit needs to be heat-sealed, the 16th, 17th, and 19th holes are not sealed firmly and are difficult to weld and seal. Even if the downward pressure is increased or the downward pressure is increased, the problem of false sealing cannot be solved. Liquid leakage after filling has brought certain adverse effects on people's use process. For this reason, we propose a gene sequencing test kit structure. Utility Model Content

After the thickness of the hot pressing film box cover is optimized, the surface thickness is increased to enhance the thermal support strength, the height of the heat sealing hole of the box cover is increased to enhance the welding firmness, and solving the problem of liquid leakage during heat sealing of the test kit, etc., which can effectively solve the problems in the background technology.

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-5 As shown, a gene sequencing reagent kit structure includes a reagent kit body 1, a No. 1 cavity 4, a No. 2 cavity 5 and a hot pressing film box cover 6, and the inner wall of the reagent kit body 1 is fixedly connected with a No. 1 positioning rib 2 and a No. 2 positioning rib 3, and the No. 1 positioning rib 2 is located on one side of the No. 2 positioning rib 3.

[0022] Furthermore, the reagent box body 1 is integrally formed with the first positioning rib 2 and the second positioning rib 3 , and the first cavity 4 and the second cavity 5 are both located inside the reagent box body 1 .

[0023] Furthermore, one side of the upper end of the hot-pressed film box cover 6 is evenly provided with box cover heat-sealing holes 8, and the number of the box cover heat-sealing holes 8 is 21 groups.

[0024] Furthermore, a cover hole boss 10 is fixedly connected to one side of the upper end of the heat-pressed film cover 6 , and the interior of the cover hole boss 10 and the interior of the cover heat-sealing hole 8 are interconnected.

[0025] Furthermore, a No. 2 box cover through hole 9 and a No. 1 box cover through hole 7 are provided at the upper end of the hot pressing film box cover 6 .

[0026] Furthermore, the upper inner wall of the reagent box body 1 and the outer wall of the hot-pressed film box cover 6 are fixed and assembled by welding.

[0027] Working principle: This solution analyzes and improves "serious glue shortage or cavity side wall perforation during injection molding" and "weak welding during heat sealing", and can obtain test kits with excellent sealing performance. The problem of weak heat sealing of holes is analyzed and improved. The left side span of the heat sealing hole 8 of the No. 17 and No. 19 box covers is larger than the right side. When the heat seal is stressed, the left side of the hole deforms greatly, and the strength is insufficient during heat sealing, followed by collapse, resulting in weak heat sealing and leakage. The thickness of the hot pressing film box cover 6 can be increased to improve the bending strength, reduce the deformation (slump), and improve the consistency and strength of the heat seal. The degree is increased, and the height of the box cover hole boss 10 connected to the box cover heat sealing hole 8 is increased, the downward pressure heat sealing amount is increased, and the welding strength is improved. When the molten glue passes through the gate and fills the No. 2 positioning rib position 3 or the No. 1 positioning rib position 2, the resistance is large and the DC resistance is relatively small. The thickness of the No. 2 positioning rib position 3 and the No. 1 positioning rib position 2 can be increased to increase the thickness of the flow layer, reduce the flow resistance, increase the flow rate, improve the filling of glue shortage and perforation, and after increasing the thickness of the No. 1 positioning rib position 2 and the No. 2 positioning rib position 3, the filling of glue shortage and perforation is improved, and a leak-proof test kit can be made.
