Bacterium counting device with blind operation indication mechanism

Abstract

The invention provides a bacterium counting device. The device comprises: a rack, wherein a plate groove is formed in the rack; a reagent plate which is located in the plate groove, wherein the reagent plate is used for containing bacterium samples to be counted; a first sensor which is positioned in the plate groove, wherein a signal of the first sensor is blocked when the reagent plate is inserted into a preset position in the plate groove; and a first indicating lamp which is arranged on the rack, wherein the first indicating lamp lights up a first color when the signal of the first sensoris blocked. Blind operation is achieved, through induction of the sensor, a computer does not need to be operated for observation, and the current door opening and closing state, the plate position in-detection state, vacancy, full load, incubation, whether waste plates exist or not and other information can be visually observed; and the current state of equipment can be recognized as soon as possible, and corresponding blind operation is conducted according to indicator lamps.

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 an indicating blind operation 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 t...
