Description

Liquid-based cell film-making subsides storehouse sealing device

Technical Field

The invention belongs to the technical field of pathological equipment, and particularly relates to a sealing device for a liquid-based cell flaking and sedimentation bin.

Background

The liquid-based cytology examination adopts a liquid-based thin-layer cell detection system to carry out cytological classification diagnosis on human body hydrothorax, ascites, urine, sputum, bronchial brush examination specimens and gynecological specimens, is a cancer cytology examination technology which is advanced internationally at present, obviously improves the satisfaction degree of the specimens and the abnormal cell detection rate of cervix compared with the traditional examination of cervical smear by scraping and pap smear, has the detection rate of the cancer cells of cervix of 100 percent, and can discover partial precancerous lesions and microbial infections such as mould, trichomonas, virus and chlamydia at the same time.

The liquid-based thin-layer cell detection method obviously improves the detection quality of cell samples, and at present, a cell sedimentation device used in the liquid-based thin-layer cell detection method is mostly manually or mechanically placed into a slide no matter a domestic or imported device, then a slide making bin with lugs is screwed into a bin seat to compress the slide, so that the slide and the sedimentation bin are sealed, and then a sample is added into the sedimentation bin to carry out sedimentation treatment. For example, a thin layer liquid-based cytology slide making bin disclosed in patent application No. 201720456304.8, a liquid-based cytology slide making unit disclosed in patent application No. 202021305178.4, and a slide making auxiliary device of a liquid-based cytology slide making system with a natural sedimentation device disclosed in patent application No. 201120305124.2 are all the screw-in type sedimentation bin fixing and sealing structures, but such structures have some defects, and before screwing in and adding the bin, a set of detection sensing control system is required, so that two ears of the sedimentation bin are ensured to be aligned to hole positions of the clamping seat.

And in the process of screwing in the feeding bin, the sealing pad of the settling bin is compressed and deformed, the surface of the sealing pad, which is contacted with the slide, has a larger friction force with the slide, sometimes the surface is relatively static with the slide, and the other surface of the sealing pad is connected with the fixed slice making bin barrel. Therefore, after screwing in, the gasket of the settling bin has not only axial compression deformation but also radial torsional deformation, after some errors occur in manufacturing precision or the equipment is worn after running for a period of time, after the mechanical claw is screwed in and added to the bin, along with the vibration of the equipment, the torsional deformation of the gasket may cause the risk of liquid leakage caused by rebound and inversion, and after cell attachment is completed, the mechanical claw takes the general motion of the bin as 5, namely, the mechanical claw descends, clamps the settling bin, rotates, rises and rotates to return. Meanwhile, in the warehouse adding and warehouse taking processes, the friction resistance generated by the relative rotation of the gasket and the glass slide can possibly cause the slipping of the mechanical clamping jaw and the settlement warehouse to cause the actual rotation of the settlement warehouse not in place, thus causing the warehouse adding and warehouse taking faults. The manufacturing cost is not reduced for the automation of adding and taking the bin.
