Hemocyte analysis chip and system for using chip thereof

Abstract

The invention provides a hemocyte analysis chip and an analysis system. The system comprises the chip, an electrical impedance detection unit and a signal processing system. The chip comprises a first detection chip and a second detection chip. The first detection chip comprises a blood sample channel, an erythrocyte lysate channel, a continuous phase channel and a first detection channel. The second detection chip comprises the blood sample channel, the continuous phase channel and a second detection channel. The blood sample channel, the erythrocyte lysate channel and the continuous phase channel of the first detection chip are communicated, and a communication position is connected with the first detection channel, the blood sample channel of the second detection chip is communicated with the continuous phase channel, and the communication position is connected with second detection channel, a small disperse aperture is provided between the connection positions of first detection channel and the second detection channel and the fluid passage, and a small detection aperture is provided at the position far from the small disperse aperture. The electrical impedance detection unit and the signal processing system use an electrical impedance method for analyzing hemocyte.

Description

technical field [0001] The invention relates to a blood cell analysis chip based on microfluidic droplet technology and a system using the chip. Background technique [0002] Blood flows through various tissues and organs of the human body, and the interaction and mutual influence between various tissues and organs of the human body is realized through the regulation and balance of nerves and body fluids. This balance is reflected in various physical parameters of blood, physiological parameters etc. The information obtained by hematological tests can help diagnose and differentially diagnose diseases related to the blood system, analyze the condition, observe the curative effect, and judge the prognosis, provide evidence for disease prevention, guide clinical medication and carry out clinical medical research. Blood cytology analysis is not only the main basis for diagnosing various diseases of the hematopoietic system, but also provides important information for the diagn...
