Embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments:

The utility model, cast-off cells prepare the cell lump wax stone with combined centrifugal pipe such as Fig. 1, Fig. 2, shown in Figure 3, comprise push pipe 1, the upper and lower ends opening of push pipe 1, be threaded or draw-in groove on the outer wall of push pipe 1 bottom, correspondence is threaded or draw-in groove on the inwall of bottom tube 4; Push pipe 1 is connected the upper end open of bottom tube 4, lower end closed by screw thread or draw-in groove with bottom tube 4.

The bottom of push pipe 1 is connected with cell lump collecting ring 2, the upper and lower ends opening of cell lump collecting ring 2, cell lump collecting ring 2 tops are bulge loop, the bottom is a seat, the inwall socket connection of the outer wall of bulge loop and push pipe 1 bottom, the outer wall of cell lump collecting ring 2 lower seat is provided with anti-skidding line.

The bottom of cell lump collecting ring 2 is connected with filtration membrane 3, is connected with filtration membrane supporting ring 5 below the filtration membrane 3, and filtration membrane supporting ring 5 can be made by plastic cement or silica gel.

On the tube wall of the screw thread of bottom tube 4 or draw-in groove below annular platform is arranged, place described cell lump collecting ring 2, filtration membrane 3, filtration membrane supporting ring 5 on the annular platform.Cell lump collecting ring 2 and filtration membrane 3 are positioned at push pipe 1 and bottom tube 4.Annular platform supports the filtration membrane supporting ring in order to connect the back with push pipe.

The utility model cast-off cells prepare the cytology wax stone with the combined centrifugal pipe by push pipe 1, cell lump collecting ring 2, filtration membrane 3, bottom tube 4, filtration membrane supporting ring 5 totally five the part form.As shown in Figure 3, make push pipe, cell lump collecting ring, filtration membrane, filtration membrane supporting ring, bottom tube form a unified integral body after push pipe and bottom tube spin.

Cell lump collecting ring 2 tops are open, and the corresponding push pipe bottom of inserting with the push pipe bottom forms insert with push pipe and is connected, the bottom outer wall is provided with the anti-skidding line of vertical arrangement, be convenient to separate with push pipe in the subsequent operations, the non-stability of bottom and filtration membrane is bonding, as adopting non-setting adhesive bonding.Filtration membrane can separate under certain external force effect with the cell lump collecting ring in the subsequent operations process, is convenient to take out cell lump.

Filtration membrane 3 adopts well known materials, and by having making such as the various material plastics films in different apertures, various absorption paper, non-woven fabrics, top and the non-stability of cell lump collecting ring are bonding, as adopting non-setting adhesive bonding.Bottom periphery is the plastic cement or the silica gel filtration membrane supporting ring of supporting role, and the filtration membrane supporting ring closely is connected with filtration membrane, can not separate.Certainly, also can not use the filtration membrane supporting ring.

Annotate: cell lump collecting ring and filtration membrane, filtration membrane supporting ring material need organic solvents such as anti-dehydrated alcohol, dimethylbenzene to soak.

Bottom tube 4 closed bottoms, volume are greater than the push pipe volume, and the top has the screw thread (or draw-in groove) that is complementary with push pipe bottom thread (or draw-in groove), and there is prominent annular platform to tube chamber the screw thread of bottom tube (or draw-in groove) below.Push pipe with make the certain pressure of generation between push pipe bottom, cell lump collecting ring, filtration membrane and the bottom tube annular platform after bottom tube is connected by screw thread (or draw-in groove), and make whole tube wall have certain antiseepage stopping property, the pressure that produces between filtration membrane and the bottom tube annular platform simultaneously compresses and fixedly filtration membrane periphery plastic cement or silica gel filtration membrane supporting ring.When push pipe separated with bottom tube, push pipe, cell lump collecting ring, filtration membrane be for having certain internuncial integral body, can with push pipe jointly with the separating and take out of bottom tube.

In the operation, cell suspension injects push pipe, after centrifugal, solid-liquid separation is taken off cell lump collecting ring and filtration membrane, and cell lump promptly is positioned at it, can enter the wax stone production process jointly and handle, when embedding, take off filtration membrane, can take out complete cell lump easily.

This centrifuge tube is that medical speciality is used for separating the preparation cast-off cells and is used to make the cell lump wax stone and uses, according to what of cell quantity in the cell suspension, select to use the centrifuge tube of different bores, make the cell lump of making have suitable thickness, guarantee slice-making quality.Cell suspension (being generally the spissated cell suspension in for the first time centrifugal back) with suitable dosage during use injects push pipe, put into horizontal centrifugal whizzer, centrifugal back liquid phase composition enters bottom tube through filtration membrane, the solid phase composition is the solid matter piece of the cell lump collecting ring internal diameter cross section columnar shape of certain rule, retain on the filtration membrane, take out centrifuge tube, after separating push pipe and bottom tube, the above composition of filtration membrane takes out with push pipe, separate with bottom tube, hold anti-skidding line place, tight cell lump collecting ring bottom again, with push pipe and cell lump collecting ring, filtration membrane separates, and will contain the cell lump collecting ring of cell lump subsequently, filtration membrane is put into dewatering box jointly and is entered the water extracter dehydration, waxdip; When embedding, behind isolated cell piece collecting ring and the filtration membrane, cell lump dehydration back volume-diminished can be separated with the cell lump collecting ring easily, can embedding production standard cytology wax stone.

Embodiment recited above is described preferred implementation of the present utility model; be not that design of the present utility model and protection domain are limited; under the prerequisite that does not break away from the utility model design concept; common engineering technical personnel make the technical solution of the utility model in this area various modification and improvement all should fall into protection domain of the present utility model.
