Abstract
The utility model discloses a cell smearing device comprising a centrifugal tube and a glass slide which are mounted in a matched way. The cell smearing device further comprises a supporting plate anda pallet integrally formed with the centrifugal tube, wherein the glass slide is arranged on the supporting plate; slots are formed on two opposite inside walls of the pallet and in corresponding positions of the supporting plate; and the two ends of the supporting plate are horizontally arranged in the slot. As the pallet and the supporting plate integrally formed with the centrifugal tube are adopted, the upper surface of the glass slide is in contact with the bottom surface of the pallet as a whole, and the entire lower surface of the glass slide is in contact with the supporting plate asa whole, thereby increasing the contact area, ensuring uniform stress of the glass slide as the entire glass slide is stressed, and preventing the glass slide from fracture.
Description
Technical field
The utility model relates to a kind of pharmaceuticals industry and exfoliative cytology, is used for to device biological, that chemical constitution is carried out the centrifuging smear, specifically a kind of cell smear device.
Background technology
At present, the centrifugal precipitation mechanisms that use carry out centrifugal, precipitation to medicine, cast-off cells etc. more when pharmaceuticals industry and exfoliative cytology smear, need suspension is added in the smear device before centrifugal.The smear device generally comprises pallet, centrifuge tube, microslide, and wherein centrifuge tube is used to hold the suspension that needs precipitation separation.When the hydro-extractor high speed rotating, under action of centrifugal force, the cast-off cells that need to separate in the suspension are deposited on the microslide.
Above-mentioned smear device, centrifuge tube and pallet are two parts, and centrifuge tube is installed on the pallet by the ears that are provided with on it.For preventing leak of liquid in the centrifuge tube, then need strengthen the pressure between centrifuge tube and microslide, make on the microslide pressure with the centrifuge tube contact portion increase like this, and on the microslide with centrifuge tube not contact portion be not under pressure, make the microslide discontinuity.Like this, when the high speed rotating of hydro-extractor, make on the microslide that the pressure with the centrifuge tube contact portion further increases, microslide is stressed more inhomogeneous, thereby causes the microslide fracture.
The utility model content
It is stressed evenly that the utility model technical issues that need to address provide a kind of microslide that makes, not the smear device of easy fracture.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of cell smear device, comprise centrifuge tube, microslide, centrifuge tube is equipped mutually with microslide, also comprise supporting plate and with the integrated pallet of centrifuge tube, microslide places on the supporting plate, be provided with slot with the supporting plate corresponding site on two relative inner walls of pallet, the both ends horizontal of supporting plate places in the slot.
As improvement of the present utility model, on the lower nozzle of centrifuge tube body, be covered with and body one-shot forming filtering membrane.
As improvement of the present utility model, the arranged outside in centrifuge tube body lower end has and the one-time formed annular flange flange of body, and the lower surface of flange is provided with the groove that is complementary with O-ring seal.
As improvement of the present utility model, the upper surface of supporting plate is provided with the boss that matches with microslide, and the lower surface of supporting plate is provided with guiding rib with the position that the pallet slot matches.
As improvement of the present utility model, with the contacted tray surface of microslide on be provided with microslide on the corresponding positioning bar of shape.
Owing to adopted technique scheme, the obtained technical progress of the utility model is: because of having adopted and integrated pallet of centrifuge tube and supporting plate, make the upper surface of microslide contact with the bottom surface integral body of pallet, the whole lower surface of microslide contacts with supporting plate integral body, increased contact area, and make microslide integral body stressed, guaranteed that microslide is stressed evenly, thereby made not easy fracture of microslide.The utility model can disposablely use, and is pollution-free; Centrifuge tube and pallet one-shot forming, the medical personnel does not need assembling before use, and is simple, convenient.

Embodiment
Below in conjunction with accompanying drawing the utility model is described in further details:
As depicted in figs. 1 and 2, cell smear device of the present utility model, centrifuge tube 1 and pallet 7 integrated injection moldings, arranged outside in centrifuge tube 1 body lower end has and the one-time formed annular flange flange of body, the lower surface of flange is provided with the groove that is complementary with O-ring seal 3, on the lower nozzle of centrifuge tube 1 body, be covered with and body one-shot forming filtering membrane 2, on two relative inner walls of pallet 7, be provided with slot, with microslide 4 contacted pallets 7 surfaces on be provided with microslide 4 on the corresponding positioning bar 6 of shape.
The upper surface of supporting plate 5 is provided with the boss 8 that matches with microslide 4, and the lower surface of supporting plate 5 is provided with guiding rib 9.
During installation, O-ring seal 3 is assemblied in the groove that is provided with on the centrifuge tube 1 body lower surface, to lie on the microslide 4 in the positioning bar 6 that pallet 7 surfaces are provided with again, at last supporting plate 5 is compressed microslide 4 by the boss 8 that is provided with on it and will be inserted in the slot that is provided with on the pallet 7.
