  • Publication number: 20230366790
    Abstract: A full-automatic preparation method of a cast-off cell smear includes the following steps: S1: pretreatment of a cast-off cell: automatically pretreating the cast-off cell to be prepared to remove interfering substances; S2: automatically transferring a pretreated cast-off cell to a cyclic settling module to allow constant-temperature settling, and staining and moisturizing the pretreated cast-off cell; and S3: subjecting a moisturized cast-off cell to automatic liquid sealing. The full-automatic preparation method of the cast-off cell smear realizes the automation of smear preparation, staining, and sealing, and also realizes the unattended high-throughput output and the high-quality smear preparation and sealing.
