Abstract

The utility model relates to a separation preserving device for sampling cell, comprising a container used to contain preserving fluid. The utility model is characterized in a plurality of raised convexes are arranged with on the vertical surface of the internal wall of the container. When the separation preserving device for sampling cell is used, the preserving fluid containing cell masses is poured into the container, and the container is placed on the swirl oscillator to be shaken. Thus, the cell masses in the preserving fluid can be broken up and be separated by the convexes on the internal wall of the container. In addition, the preserving fluid has discrete characteristic. Finally, the cell masses in the preserving fluid can be broken up thoroughly, but the single cell is not damaged. The cell smear can be made by using the cells which are broken up to improve the quality of the cell smear. The utility model has the advantages of simple structure and low price and is easy to be used widely.

Description

Sampling cell separation conservator

Technical field

The utility model relates to medical instruments field, in particular for making uterine neck sampling cell smear, and the cell that collects is carried out the utensil of separating treatment.

Background technology

In the medical diagnosis and treatment and research process of relevant gynecological disease, people often need to gather cell at uterus neck, then the cell that collects are made cell smear, for deliberation and diagnosis.The method that present people make cell smear, the cotton swab that just will stick the cell of sampling is usually directly smeared on slide.The shortcoming of this method for making is to have only small amounts of cells to transfer on the slide, transfers to the dry easily distortion of cell on the slide, and the cellular layer became uneven that forms on slide, and is overlapping serious, influences inspections and examinations.Other has a kind of more advanced processing mode,, finishes with a whole set of expensive equipment to drawing diagnostic result from cell collection.Though this mode is advanced, used device structure complexity, cost an arm and a leg, at present main dependence on import all is difficult to bear for medium and small hospital and research unit, therefore fails to be applied.

Summary of the invention

The purpose of this utility model provides a kind of quality that improves cell smear, and sampling cell separation conservator with low cost.

The utility model is achieved in that sampling cell separation conservator has one and bears the container of preserving liquid, especially, is provided with the newborn protruding of a plurality of projectioies on the inwall risers of container.During use, earlier the cell on the collectors such as cotton swab is eluted in the preservation liquid in the container, then container is placed on and does the concussion processing on the vortex oscillator, make cell high speed rotating in container of preserving in the liquid, so newborn protruding on cell mass and the container inner wall frequently comes in contact collision, the cell mass of preserving in the liquid in collision process will be broken up separation, preserves the discrete feature of liquid in addition, and the final feasible cell mass of preserving in the liquid is thoroughly broken up and unicellular being without prejudice.Utilize these cells of having been broken up to make cell smear, can significantly improve the quality of cell smear.

The utility model has the advantages that: the impact effect that utilizes newborn protruding pair cell to roll into a ball, preserve the debunching action of liquid in addition, make in the sample sticking at random and cell mass, suspension as discrete formation homogeneous disperses such as mucus group, inflammatory cell groups, improved the quality of follow-up making cell smear, and utensil structure is simple, and is cheap, is highly susceptible to popularization and application.

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 is the A-A part sectioned view of Fig. 1.

Embodiment

Referring to Fig. 1, sampling cell separation conservator has one and bears the container 1 of preserving liquid, is provided with newborn protruding 2 of a plurality of projectioies on the inwall risers of container.When container 1 is placed on when shaking on the vortex oscillator, breast protruding 2 will be broken up separation with the cell mass of preserving in the liquid in the container.Breast protruding 2 can be with container 1 global formation.As further improvement, present embodiment has also been inserted stirring rod 3 in container 1.Stirring rod 3 can strengthen preserving the agitaion of liquid, makes the easier quilt of cell mass break up separation.The container 1 of present embodiment is provided with a top cover 4, and stirring rod 3 is fixing with top cover 4.Just stirring rod 3 can be taken away together as long as start top cover 4, be convenient to like this in container 1, pour and pour out preservation liquid into, not be subjected to stopping of stirring rod 3.As preferred forms, the container 1 of present embodiment is open-topped pipe shape, and the intracavity bottom 1a of container is recessed arc surface.Help the cell centrifugation precipitation like this.The shape of cross section of stirring rod 3 can be a different shape, star etc. for example, and complicated more helping more of shape broken up cell mass, but too complicated shape can make cell be easy to attached on the stirring rod again.Therefore as optimum shape, the hypomere position of the stirring rod 3 in Fig. 1, the xsect of stirring rod is an equilateral quadrilateral shown in Figure 2, and equilateral in addition pentagon or equilateral hexagon also are alternative optimum shapes, and can be that whole piece stirring rod 3 all adopts with a kind of shape of cross section.Equilateral quadrilateral, equilateral pentagon or equilateral hexagon can both make stirring rod 3 both have the beating action of sufficient intensity, can not make hypercellularity ground attached on the stirring rod 3 again.

Illustrate the concrete using method of present embodiment below: the top cover 4 of opening container earlier, stirring rod 3 is taken out together, to preserve liquid then pours in the container 1, again the cell on the collectors such as cotton swab is eluted in and preserves in the liquid, cover top cover 4, then container 1 is placed on the vortex oscillator and shakes, concussion along with container, preserve the cell high speed rotating in container 1 in the liquid, breast protruding 2 will be broken up the cell in the preservation liquid rapidly with stirring rod 3 and separate, preserve the debunching action of liquid in addition, the final suspension that forms the homogeneous disperse then leaves standstill a period of time with container 1 again, makes cell precipitation at container bottom, again supernatant is removed, make remaining sedimentation cell and small amount of liquid in the container 1,, thereby form high-concentration turbid liquor again with vortex oscillator vibrations container 1, with pipettor a certain amount of high-concentration turbid liquor is transferred on the slide at last, just can be made the uniform cell smear of cellular layer thickness.

The utility model not only can be used for improving the quality of cervical cell smear, also can be used for improving the cell smear quality of other position cells, for example improves the cell smear quality of esophagus cell.
