AI Technical Summary
Existing sperm analyzers require the semen to stand still and liquefy before testing, resulting in low testing efficiency and reduced sperm motility. The low efficiency of processing difficult-to-liquefy semen makes it difficult to meet the needs of batch testing.
A sample pretreatment structure for a sperm analyzer is designed, comprising a water bath, a rotating support, and a heating component. The rotating drive component causes the semen tube to rotate and mix the liquefying agent, while the heating component regulates the temperature to achieve rapid and uniform mixing and heating of the semen.
It improves the semen liquefaction rate, maintains sperm motility, enhances detection accuracy and efficiency, and meets the needs of batch testing.
