Embodiment Construction
[0033] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0034] Such as Figure 1-Figure 4 As shown, a cleaning unit provided in this embodiment is applied to the flushing of the drainage unit of the cell extractor 100, including: a driving mechanism 200, a cleaning fixture 300, a cleaning port 400 and a cleaning pipeline 500; the cleaning port 400 is set On the cleaning fixture 300, the cleaning port 400 is connected to the cleaning pipeline 500. The cleaning pipeline 500 is used to transport the external cleaning liquid to the cleaning port 400. The cleaning fixture 300 pass...

The invention provides a cleaning unit and a cell extractor, and relates to the technical field of cell extraction. The cleaning unit comprises a driving mechanism, a cleaning fixing frame, a cleaning port and a cleaning pipeline. After cell sample extraction is completed and a sample cup is separated from a liquid discharge port, a cleaning fixing frame is driven by the driving mechanism to move relative to a fixing frame of the cell extractor, so that the cleaning port is moved to the liquid discharge port of a liquid discharge unit, and the cleaning port is detachably connected with the liquid discharge port. External cleaning liquid is conveyed into the liquid discharging port and an internal channel of the liquid discharging unit through the cleaning port, mechanical corresponding cleaning of the liquid discharging unit is achieved, manual operation is reduced, the influence caused by pollution of the liquid discharging channel of the liquid discharging unit is avoided, the operation efficiency is improved, and inconvenience caused by manual operation is avoided; and the technical problems that in the prior art, when the liquid discharging unit of the cell extractor is manually washed, manpower is consumed, it cannot be guaranteed that the liquid discharge port and an internal pipeline are cleaned thoroughly, and pollution is likely to be caused are solved.
Description
technical field [0001] The invention relates to the technical field of cell extraction, in particular to a cleaning unit and a cell extraction instrument. Background technique [0002] In criminal cases, it is not uncommon to see blood-stained cigarette butts, gloves and other biological samples mixed with exfoliated epithelial cells left by suspects at the scene. Due to the contamination of the victim's blood, routine DNA tests are mostly mixed STR (short tandem repeat sequence) typing, and even only a single STR typing of the victim is obtained due to the dominant amplification of human blood DNA, which not only increases the difficulty of result interpretation , more likely to lose strong evidence against the suspect. [0003] In the prior art, research on cell separation methods for mixed biological samples mainly includes: immunomagnetic bead directional capture, flow cytometry, microcapture, laser capture microdissection and microfluidic chip technology. Accurate and...
