Description

Technical Field

[0001] The utility model relates to the field of biological detection, in particular to a reagent mixer for biological sample detection. Background Art

[0002] After searching Chinese patents, the publication number is: CN217614318U, a reagent mixer for biological sample detection, which relates to the field of biological sample processing technology. The reagent mixer for biological sample detection includes a base plate, the lower surface of the base plate is fixedly connected to a support leg, the upper surface of the base plate is detachably connected to a protective shell, the internal rotation of the protective shell is connected to a main rotating shaft, the outer surface of the main rotating shaft is fixedly connected to a main gear, and a secondary rotating shaft is provided inside the protective shell and on the outside of the main rotating shaft. In the present utility model, the mixing seat is driven to rotate by a motor, and the sample mixing tubes can be automatically mixed, which not only ensures a good mixing effect, but also does not require manual holding, and is relatively easy and convenient to use. Through the mutual cooperation of the mixing seat, the insertion slot, and the placement rack, multiple sample mixing tubes can be placed at one time, which is convenient for mixing multiple samples at the same time, improves the mixing efficiency, and is suitable for situations where the sample volume is large.

[0003] To sum up, the mixing efficiency of the reagent mixer is low. The mixer drives the mixing seat to rotate by a motor, and can automatically mix the sample mixing tube. During mixing, the sample can only be rotated. The sample is mixed only by rotation. The mixing time is long and the mixing efficiency is low, which reduces the working efficiency. The mixing seat cannot be replaced. The mixing seat of the mixer is fixedly connected to the top of the secondary rotating shaft, and the size of the mixing seat is fixed, so that it can only be used for one size of placement rack. If you want to use placement racks of different sizes, you need to replace the device, which increases the use cost, reduces practicality and applicability, and is inconvenient to use. In order to solve the above problems, we propose a reagent mixer for biological sample detection. Utility Model Content
