Abstract

The invention provides a bacterium counting device. The device comprises a sampling assembly which comprises a three-dimensional motion mechanical arm and a sampling needle, the three-dimensional motion mechanical arm is used for driving the sampling needle to suck to-be-counted bacterium samples from a reagent plate, and the sampling needle is used for adding the sucked to-be-counted bacterium samples into a counting pool assembly; and a pump is connected to the sampling needle through a liquid path and used for uniformly mixing the to-be-counted bacterium samples sucked by the sampling needle, when the pump works in a first mode, a liquid in the liquid path is pushed to flow to the sampling needle, and when the pump works in a second mode, the liquid in the sampling needle is sucked intothe liquid path. Before sample absorption and after sample absorption, uniform mixing is carried out twice, sufficient mixing of to-be-detected samples is guaranteed, statistics of the number of bacteria in the detection process is more accurate, uniform mixing operation is carried out in the equipment, other auxiliary uniform mixing equipment is not needed, and the pollution rate is reduced.

Description

technical field [0001] The invention relates to the field of biology, and further relates to a bacteria counting device, in particular to a bacteria counting device with a bubble mixing mechanism. Background technique [0002] A cell counter mostly refers to an instrument that measures the number of platelets, white blood cells, and red blood cells. Fully automatic cell counters are widely used, and the technical solution Coulter's principle analysis method has always been an internationally recognized standard control method for measuring cell and particle size, and has always occupied an important position in hematology analysis. [0003] The resistance counting method is the Coulter method, which uses the principle of small hole resistance to measure the number of particles. The particles flow with the liquid during the measurement. When it passes through the small hole, the cross-sectional area of ​​the small hole becomes smaller, the resistance between the two electro...
