a mixing device

Abstract

The invention relates to the technical field of medical testing equipment, in particular to a mixing device, which includes a reagent turntable that can rotate itself and a reagent seat that is eccentrically arranged on the reagent turntable, the reagent seat can rotate itself, and a connecting seat that can rotate in the reagent seat The mixing device of the present invention is provided with at least two rotatable reagent seats eccentrically in the rotatable reagent turntable, and at least one rotatable connecting seat is arranged in the reagent seat, and the connecting seat can accommodate reagents. When working, The reagent turntable rotates to select the reagent base that needs to be mixed, so that the reagent base is connected to the power source. When the reagent base rotates, it also drives the connection base to rotate in the reagent base, avoiding the drag pollution problem caused by the traditional stirring type, and improving Working efficiency, the bottom of the loading base is equipped with a refrigeration component, which conducts heat through an external water-cooled pump, reduces the size of the device, and improves the efficiency of heat conversion.

Description

technical field [0001] The invention relates to the technical field of medical testing equipment, in particular to a mixing device. Background technique [0002] At present, the reagent bottles of magnetic beads and magnetic sheets need to be mixed before pipetting, so that the components of the reagent bottles for each pipetting are very close; and the mixing devices on the market mostly use stirring rods Stir well or use a pipette needle to repeatedly suck and vomit, but this method is likely to cause contamination when different reagent bottles are mixed, and the stirring rod needs to be cleaned before the next mixing operation, and its work efficiency is low; moreover, the immune reaction experiment Such reagent bottles usually need to be stored in an environment of 4°C~8°C. Commonly used refrigeration devices on the market usually use a cooling module that combines heat sinks, cooling fins, and heat dissipation fans. The disadvantage is that the noise of the heat dissip...

[0002] At present, the reagent bottles of magnetic beads and magnetic sheets need to be mixed before pipetting, so that the components of the reagent bottles for each pipetting are very close; and the mixing devices on the market mostly use stirring rods Stir well or use a pipette needle to repeatedly suck and vomit, but this method is likely to cause contamination when different reagent bottles are mixed, and the stirring rod needs to be cleaned before the next mixing operation, and its work efficiency is low; moreover, the immune reaction experiment Such reagent bottles usually need to be stored in an environment of 4°C~8°C. Commonly used refrigeration devices on the market usually use a cooling module that combines heat sinks, cooling fins, and heat dissipation fans. The disadvantage is that the noise of the heat dissipation fan during instrument operation In addition, it is necessary to design a cooling space and hot air flow export in the device, which makes the size of the device larger and its heat conversion efficiency is low
