Abstract

The utility model relates to a tabletting clamp used for preparing liquid based thin cell sheets in biological cytology. The tabletting clamp consists of a liquid cylinder, a filtering membrane, a glass groove and a glass slide. The tabletting clamp is characterized in that a dropper is fixed on the liquid cylinder; the glass slide is inserted in the glass groove; filter paper is arranged between the filtering membrane and the glass slide. As a hanging dish is matched with the tabletting clamp by adopting the mode of a dropper and a hanging scroll, the tabletting clamp is operated conveniently and used simply. As such structures as the filtering membrane, the filter paper and so on are adopted, the cell sheets prepared are in good shape and uniform, laid flatly in a single layer with clean background. During the production run, as the structure is simple, the tabletting clamps can be used in most cases by adopting standard parts or simply rebuilding the tabletting clamps; the tabletting clamps are produced simply, and the cost is low.

Description

A kind of liquid based thin-layer cell film-making folder

Technical field

The utility model relates to a kind of film-making folder that biocytology is manufactured liquid based thin-layer cell sheet that is used for.

Background technology

Liquid based thin-layer cell flaking method utilizes liquid base technology exactly, and useful cell transfer to microslide, is formed that cell is neat evenly, individual layer tiling, the clean cell sheet of background, so that researchist's observational study clearly.The liquid based thin-layer cell production facility of present most economical practicality all adopts the mode of centrifugal force transitional cell.This equipment generally includes special-purpose centrifugal rotor and special-purpose film-making folder, and the cell that also contains that has is preserved devices such as bottle.This equipment exists in actual use that easy-offtaking film-making folder and slide, film-making folder are not installed deficiencies such as insecure or complicated operating process; Exist problems such as complex process and input height in process of production.

Summary of the invention

Exist slide and film-making to press from both sides easy-offtaking not, the deficiency that insecure, film-making process complexity etc. is used is installed in order to overcome existing liquid based thin-layer cell production facility, with the difficulty that solves in complex process, the high manufacturing of production cost, the utility model provides a kind of liquid based thin-layer cell film-making folder, this film-making folder is not only simple to operation, safe in utilization, and manufacturing process is simple, with low cost.

The technical scheme that its technical matters that solves the utility model adopts is: a kind of liquid based thin-layer cell film-making folder, form by liquid cylinder, filtering membrane, slide groove and microslide, it is characterized in that fixing on the liquid cylinder and link up with, microslide inserts and is installed in the slide groove, between filtering membrane and the microslide filter paper is installed.During film-making, hook on the film-making folder is hung on the extension dish of centrifugal rotor, film-making is clipped under the action of centrifugal force and is turned near horizontality, useful cell-penetrating filtering membrane is transferred on the microslide in the liquid cylinder, impurity is filtered film and blocks, the film-making area equates that with the filtering membrane area formation cell is neat evenly, individual layer tiles, the clean cell sheet of background, reaches the purpose of quick Fabrication liquid based thin-layer cell sheet.

The beneficial effects of the utility model are: in use, because the mode of linking up with has been adopted in cooperating of extension dish and film-making folder, thus easy to operate, use simply, install firmly, move safety and stability more, economical and practical; Owing to adopted frame modes such as filtering membrane, filter paper, the cell sheet cell of making is neat evenly, individual layer tiles, background is clean.In process of production, because simple in structure, majority adopts standard components or it is just transformed simply and can use, and produces simple, with low cost.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further specified.

Fig. 1 is the structural drawing of film-making folder.

Embodiment

In Fig. 1, fixing on the liquid cylinder 1 and linking up with 2, filtering membrane 3 is fixed on liquid cylinder, insert in the slide groove 6 microslide 5 is installed, between filtering membrane 3 and the microslide 5 filter paper 4 is installed, for guaranteeing that microslide 5 can not come off when the centrifugal motion, the degree of depth that smear presss from both sides 2 slide grooves is little, is advisable to clamp microslide 5; For guaranteeing to make things convenient for the length that extraction filter paper 4 and microslide 5, smear press from both sides 2 slide grooves to lack, generally be not more than 3/4ths of microslide 5 length.When the centrifugal rotor rotating operation, under action of centrifugal force, smear folder 2 can upwards be turned to horizontal direction along the axis of extension dish, liquid in the folder etc. are along the direction motion of centrifugal force, bigger impurity etc. is filtered film 3 and blocks, cell and liquid pass filtering membrane 3, and cell all attaches on the microslide 5, and liquid is sponged by filter paper 4.Behind centrifugal the finishing, smear folder 2 can return to the vertical hanging state, takes out smear folder 2, and microslide 5 and filter paper 4 are extracted out simultaneously, separates microslide 5 and filter paper 4, and the cell sheet completes.

Hook 2 on the liquid cylinder 1 is an one, also hook 2 can be fixed on the liquid cylinder in modes such as bonding or rivet connections.

Claims

1, a kind of liquid based thin-layer cell film-making folder, form by liquid cylinder (1), filtering membrane (3), slide groove (6) and microslide (5), it is characterized in that fixing on the liquid cylinder (1) hook (2), microslide (5) inserts and is installed in the slide groove (6), between filtering membrane (3) and the microslide (5) filter paper (4) is installed.
