Abstract

The invention discloses a sperm quality fast detection system and detection method based on a micro-fluidic chip. The system comprises the micro-fluidic chip, a reader and an intelligent terminal, wherein the micro-fluidic chip comprises a micro-fluidic channel unit plate and a substrate; the micro-fluidic channel unit plate is arranged on the substrate; the micro-fluidic channel unit plate comprises an inlet, a micro-fluidic channel, micro cavities and an air channel; one end of the micro-fluidic channel communicates with the inlet; the other end of the micro-fluidic communicates with n micro cavities arranged at equal distance; the air channel and the micro-fluidic channel are positioned on the same plane and are in adjacent arrangement; one end of the air channel is connected with a finger membrane pump; the other end of the air channel is sealed; an umbrella-shaped one-way micro valve is arranged on a trunk path of the air channel; an air overflow hole is formed in the umbrella-shaped one-way micro valve; the micro cavities are adjacent to the air channel; the reader comprises a first lens group, a second lens group, a lens barrel, a focusing screw and a light source; a camera of the intelligent terminal is aligned with the lens barrel of the reader.

Description

technical field [0001] The invention relates to the field of microfluidics, in particular to a microfluidic chip-based rapid sperm quality detection system and detection method. Background technique [0002] Sperm motility refers to the percentage of progressive motility sperm in semen. Since only sperm with progressive motility can have normal viability and fertilization ability, motility is closely related to female conception rate. Sperm survival rate (sperm survival rate) refers to the proportion of live sperm in semen, and the survival rate of sperm is evaluated by testing the integrity of sperm membrane. Eosin is commonly used in medicine for sperm survival test. In the test, the heads of live sperm are white and light pink, and the heads of dead sperm are red and dark pink. The lower limit of the reference value for sperm viability is 58%. Total number of sperm (total number of sperm) refers to the total number of sperm in a complete ejaculation, calculated by mult...
