Abstract

The invention provides a bacterium counting device. The bacterium counting device comprises a sampling assembly, a counting cell assembly and a circuit control system, wherein the sampling assembly isused for obtaining bacterium samples to be counted; the counting cell assembly comprises a jewel hole, a front cell, a rear cell and electrodes; the front cell and the rear cell communicate through the jewel hole, the electrodes are respectively arranged on two sides of the jewel hole, and liquid pressure between the front cell and the rear cell is negative pressure and is used for enabling the bacterium samples to be counted to enter the rear cell from the front cell through the jewel hole; and the circuit control system is used for detecting the number of bacteria in the bacterium samples to be counted according to pulse signals under the condition that pulse signals are generated on two sides of the jewel hole, and the pulse signals are used for indicating that the bacteria in the bacterium samples to be counted pass through the jewel hole.

Description

technical field [0001] The invention relates to the field of biomedicine, in particular to a bacteria counting device and a method thereof. 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 counting device and method applied to bacteria in the prior art also has the following problems: ① currently there is no equipment on the market that utilizes the resistance counting method to measure the number of bacteria. ②The diameter of the jewel hole of the existing cell counter is suitable for measuring red blood cells, white blood cells and other large-sized cells, ensuring that th...
