Description

Detection reagent storage box and detection reagents

The present invention relates to a detection reagent, and in particular to a storage box for detection reagents that can accommodate multiple test strips.

According to today's epidemic of various infectious diseases, in order to effectively prevent the spread of diseases, in addition to various anti-epidemic measures in daily life, immediate testing and isolation of those at risk of disease are also very important. Among them, the ability to quickly and roughly screen Rapid screening test reagents for detecting whether you are infected or not are not only highly relied upon by medical institutions, but even ordinary people purchase them for self-screening on a daily basis.

Common structures of rapid screening reagents, such as those disclosed in patents CN105548494A, TWM537659U, etc., include a hollow shell and a test paper placed inside the shell.

The test paper 200b is guided by the slope part to tilt downward toward the first end 101, which can ensure the accurate position of the test paper.

In addition, in order to further position the test strip, a first ring 16a and a second ring 16b are respectively protruded around the first observation window 12a and the second observation window 12 on the side of the top wall 10 facing the bottom wall 20 , the side of the bottom wall 20 facing the top wall 10 is provided with at least a first resisting convex portion 26a and a second resisting convex portion 26b, the first resisting convex portion 26a and the second resisting convex portion 26b The positions correspond to the first observation window 12a and the second observation window 12b respectively. The first ring edge 16a and the second ring edge 16b respectively abut the top surfaces of the first test paper 200a and the second test paper 200b. An abutting protrusion 26a and the second abutting protrusion 26b respectively abut the bottom surfaces of the first test paper 200a and the second test paper 200b.

Not only that, in this embodiment, at least a third pressing protrusion 17a and a fourth pressing protrusion 17b are protruding from the side of the top wall 10 facing the bottom wall 20, and the bottom wall 20 faces the top wall. There is at least a third supporting convex part 27a and a fourth supporting convex part 27b protruding from one side of the 10. The third pressing convex part 17a corresponds to the position of the third supporting convex part 27a for keeping the first test paper 200a farther away. One end of the first end 101 is sandwiched therebetween, and the fourth pressing protrusion 17b is positioned correspondingly with the fourth supporting protrusion 27b for sandwiching the end of the second test paper 200b farther away from the first end 101 therebetween.

In addition to the above positioning measures, other positioning structures can be added at appropriate locations. For example, the top wall is provided with transversely extending transverse ribs between the drip port and the observation windows, and the position of the transverse ribs corresponds to the first supporting protrusion. and the second support protrusion, so that the first test paper and the second test paper are sandwiched between the transverse ribs and the first support protrusion and the second support protrusion; the bottom wall may also have a plurality of positioning ribs near the second end, The test paper is limited from the left and right sides of each test paper, and is blocked by one end of the test paper close to the second end, so that the test paper is accurately positioned on the bottom wall.

It should be noted in particular that, in order to facilitate manufacturing and insert test strips, the detection reagent container is preferably composed of upper and lower shell halves, with the top wall and the bottom wall respectively located on the two half shells. The two half shells can be assembled and fixed by matching each other through the insertion structure of the protruding pillars and the receiving grooves in this embodiment, but it is not limited to this.

In practice, placing the two suction tanks on the left and right sides of the drip tank to make them symmetrical can ensure that the speed and liquid volume of the test solution flowing to the two suction tanks are roughly equal. However, the position of the suction tank and the position of the test paper still need to be arranged. It can be adjusted according to actual needs and differences.

With the detection reagent provided by the present invention, multiple test strips can be installed in a single container to perform multiple tests of the same detection, or different types of detection. The important thing is that only a single sampling and dripping is required. Multiple test strips are supplied at the same time, which not only saves time and effort, but also makes full use of the sampling test solution, which is very convenient.

In this way, the detection reagent storage box and detection reagent provided by the present invention can simplify the procedures required for multiple detections under the premise of maintaining detection conditions, which is indeed expected by the relevant industry.
