Abstract

The invention provides a bacterium counting device which comprises a sampling assembly, a counting cell assembly and a circuit control system, wherein the sampling assembly is used for sequentially acquiring to-be-counted bacterium samples of which concentration is from low to high from a reagent plate and adding the to-be-counted bacterium samples into a counting cell assembly; the counting cellassembly comprises a jewel hole, a front cell, a rear cell, electrodes and a waste fluid port positioned below the counting cell assembly; the front cell and the rear cell are communicated through thejewel hole; two electrodes are respectively arranged on both sides of the jewel hole; the to-be-counted bacterium samples enter the rear cell from the front cell through the jewel hole; the circuit control system is used for determining a number of bacteria in the to-be-counted bacterium samples according to pulse signals in a case of detecting out the pulse signals generated on both the sides ofthe jewel hole; and the pulse signals are used for representing that the bacteria in the to-be-counted bacterium samples pass through the jewel hole.

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 non-cleaning 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 electrod...
