The detection reagent used in POCT includes a magnetic bead solution, which is a solution containing magnetic particles. In the research of the present application, it is found that, during transportation, due to unavoidable jolt, shaking, etc., magnetic particles in a magnetic bead solution are easy to be separated from the solution and stick to a sealing film of a container for storing the magnetic bead solution or a sidewall close to the sealing film, and sputtering of the magnetic particles in the magnetic bead solution may cause a change in characteristics of the magnetic bead solution (e.g., a decrease in effective amount), thereby affecting accuracy of a detection result. Therefore, the packaging box 10 improves the situation that the magnetic particles are easy to be separated from the solution during transportation by arranging the magnetic fixing member 120 in the box body 110, so that the accuracy of the reagent in the reagent strip 20 during use is improved.

Specifically, the box body 110 includes a box wall and a box bottom connected to the box wall, the box wall and the box bottom enclose a containing cavity for containing the reagent tank 111, and the box body 110 has an opening communicated with the containing cavity. The reagent tank 111 is used for mounting the reagent strip 20. The reagent strip 20 is a container for storing reagents, and a cavity capable of storing the reagents is arranged on the reagent strip 20. Of course, there is at least one chamber on the test strip 20 in which reagents can be stored. In one specific example, the reagent strip 20 is provided with a plurality of cavities which are independent from each other and are arranged side by side and can store reagents. The reagent groove 111 is positioned in the accommodating cavity, and the reagent groove 111 is fixedly connected with the box wall and/or the box bottom. More specifically, the reagent reservoir 111 has a reservoir bottom 111a and a side wall 111b connected to the reservoir bottom 111a, the reservoir bottom 111a being fixedly connected to the cartridge bottom and/or the side wall 111b being fixedly connected to the cartridge wall. The reagent well 111 has a notch, which is away from the well bottom 111a, in the same orientation as the opening. Herein, the fixing connection means between the two elements is not particularly limited, unless otherwise specified. For example, the two elements may be at least one of screwed and clamped, or may be fixed to each other by other means, such as welding.

In some embodiments, reagent reservoir 111 is a separate reservoir from cartridge 110. At this time, the groove bottom 111a is fixedly connected to the box bottom and/or the side wall 111b is fixedly connected to the box wall. In other embodiments, cassette body 110 cooperates with a partition fixed within cassette body 110 to define reagent reservoir 111. In this case, a part of the side wall 111b of the reagent well 111 is a wall of the cartridge case 110, the other part of the side wall 111b of the reagent well 111 is a partition, and the bottom 111a of the reagent well 111 is a part of the cartridge bottom.

Optionally, the magnetic fixture 120 is fixed to the groove bottom 111a and/or the side wall 111b near the groove bottom 111 a. Fixing the magnetic fixing member 120 in the reagent tank 111 can reduce the shaking of the magnetic fixing member 120 during transportation, thereby reducing the shaking of the magnetic particles in the magnetic bead solution in the reagent strip 20. In one embodiment, the magnetic mount 120 is fixed to the groove bottom 111 a. In another embodiment, the magnetic mount 120 is fixed to the side wall 111b near the slot bottom 111 a.

In this case, the magnetic fixing member 120 may be fixed on the groove bottom 111a under the condition that the reagent strip 20 is loaded by cooperation of other components. For example, in use, the bottom of the reagent strip 20 abuts against the magnetic fixture 120 by the fixed connection between the outer wall of the reagent strip 20 and the reagent tank 111, so that the magnetic fixture 120 is fixed on the bottom 111a of the reagent tank. Of course, when the reagent strip 20 is loaded, the magnetic holder 120 may move within a certain range as long as the movement of the magnetic holder 120 does not cause the magnetic fine particles to come off the magnetic bead solution.

Optionally, at least one of the side wall 111b and the slot bottom 111a is fixedly attached to the outer wall of the reagent strip 20.

At this time, the stopper 130 functions to prevent the magnetic fixing member 120 from being easily removed from the reagent tank 111. Of course, in some embodiments, the limiting member 130 may also be used to cooperate with the groove bottom 111a to fix the magnetic fixing member 120 directly on the groove bottom 111 a.

In the illustrated embodiment, there are three limiting members 130, and the three limiting members 130 are disposed on the side walls 111b of two adjacent reagent vessels 111 at intervals. It is understood that, in some other embodiments, the limiting member 130 may be omitted, and in this case, a notch may be formed on the wall of the reagent tank 111 to form a limiting portion capable of holding the magnetic fixing member 120 on the tank bottom 111a, and the magnetic fixing member 120 is fixed on the tank bottom 111a through the limiting portion.

It is understood that in other embodiments, the reagent cuvette 111 is not limited to an elongated shape, as long as it fits into the reagent strip 20. For example, when the reagent strip 20 has only one chamber and the outer wall of the chamber is tapered in the upper and lower directions, the hollow portion of the reagent reservoir 111 may be tapered. Of course, the shape of the magnetic fixing member 120 is not limited to the elongated shape, and may be any other shape. It is understood that the number of the reagent well 111 may be one.
