Reagent bottle with potent shaking well function

Abstract

The invention relates to a reagent bottle with a potent shaking well function. During using, due to the action of gravity, magnetic beads aggregate at the center of the bottom of a bottle body, and the reagent bottle can perform circulation forward and reverse self-rotation along with the rotation of an instrument; when rotation starts, the reagent bottle can rotate immediately, at the time, magnetic bead liquid above bottom fillets can roll over upwardly under the upward action of oblique slopes on the two sides of the bottom fillets, the magnetic beads are driven by water flow and elevates upwardly, but upward action of the bottom fillets is limited, and the magnetic beads cannot roll over quickly to the uppermost layer of the reagent bottle; at the time, two fillets of the side wall areprovided with same oblique slopes, the magnetic bead liquid is subjected to the action of the fillets of the side wall and then aggregates inwardly, due to the fact that the two fillets are symmetrically distributed, and two parts of the magnetic bead liquid aggregate inwardly and impact on each other, so that the magnetic bead liquid further has a stirring action on the rolled-over magnetic beads during rotation; and the two fillets cooperate with each other to realize rapid shaking well of the magnetic beads.

Description

technical field [0001] The application belongs to the technical field of medical devices, and in particular relates to a reagent bottle with a powerful shaking function. Background technique [0002] In medical equipment, reagent bottles are used to store, transport and use reagents required for experiments. After the reagents are stored, due to standing for a long time, the reagents in the reagent bottles are likely to be uneven. If they are directly used in the experiment, the experimental results will be incorrect. [0003] In the field of chemiluminescence immunoassay, a commonly used reagent is magnetic particles. Since the magnetic beads are nano-scale magnetic materials and insoluble in water, this reagent is very easy to precipitate. [0004] The general chemiluminescence immunoassay analyzer uses the method of rotating the reagent bottle to shake well. Since the dead volume of the reagent bottle should be minimized, it is generally designed with a round bottom to r...

AI Technical Summary

Problems solved by technology

This round bottom design causes the magnetic beads to concentrate in the center of the bottom of the bottle. In addition, the inner wall of the reagent bottle is smooth. When the reagent bottle is rotated, the shaking effect on the magnetic beads is extremely poor.
