Abstract
The invention provides a preparation device for a cell smear. The preparation device includes a thin plastic sheet, wherein a smooth working plane in sliding contact with a glass slide during the smear preparation is arranged on an A edge of the thin plastic sheet; the included angle of the working plane and the thickness direction of the thin sheet is alpha; the A edge is provided with a straight flute extending in the direction of the A edge; and the opening of the straight flute is arranged on the working plane. As the working edge, namely the A edge of the thin plastic sheet is provided with the straight flute, according to the capillary suction principle, cell sap drops quickly and uniformly expand in the straight flute when the cell sap drops on the glass slide are contacted with the working edge during the smear preparation, later, the thin plastic sheet is pulled, the smooth working plane of the working edge slides on the glass slide, and a uniform coating is formed; as the smooth plane made of plastic is in sliding contact with the glass slide, the coating is uniform and has no scratch, and the possibility of causing mechanical injury to the cells is low; besides, the preparation device for the cell smear adopts the pulling process rather than the pushing process, thereby being simple in the operation process and easy to implement.
Description
Technical field
The present invention relates to the cell smear technical field, be specifically related to a kind of cell smear production of coatings device.
Background technology
The cell smear method is that material (blood, marrow, urine etc.) is coated on a kind of flaking method on the glass slide equably.Fig. 1 is that example shows existing smear production of coatings process, A with blood: a certain amount of drop of blood 3 is dropped on the microslide 1; B: then with the lower edge contact drop of blood of push jack 2, according to infiltration phenomenon, drop of blood is in the push jack border extended; C and D: push jack and microslide angle are 30～45 °, promote gently from right to left, form coating.Because the edge of glass push jack is sharp-pointed and uneven under microscopic state, causes the cell coated wavy cut that has, coating is inhomogeneous.Push jack is actual to be an other microslide, the easy damaged portion cell of the mechanical friction of glass push jack lower edge and microslide.In addition, during push jack 30-45 ° of acute angle, be the process of " pushing away ", need professional training can release comparatively ideal smear.
Summary of the invention
The technical matters that the present invention will solve provides a kind of cell smear preparing device.
In order to solve the problems of the technologies described above, technical scheme of the present invention is:
A kind of cell smear preparing device; Comprise plastic tab; The A limit of this plastic tab has at smear and prepares in the process the smooth working face with the microslide sliding contact; This working face and sheet thickness direction have angle, and this A limit has the straight trough that extends along this edge direction, and straight trough is opened on the working face.
Above-mentioned cell smear preparing device, said plastic tab 0.1～0.3mm is thick and have certain elasticity.
Above-mentioned cell smear preparing device, said angle span: 45 °～60 °.
Above-mentioned cell smear preparing device, said straight trough opening is near the place, obtuse angle on said A limit.
Above-mentioned cell smear preparing device, the A limit of said plastic tab are and are fixed under the naked state on the plastic tab fixed mount, and this fixed mount is provided with the handle that supplies the operator to grip.
Above-mentioned cell smear preparing device, the bending direction of said handle and said A limit acute angle point to roughly opposite.
Above-mentioned cell smear preparing device, said plastic tab and fixed mount are one-body molded, and the relative edge on said A limit and fixed mount form connecting portion.
The working edge of plastic tab (being the A limit) has straight trough, prepares in the process at smear, when the cell drop on this working edge contact microslide, inhales principle according to hair, and cell liquid drops in the straight trough to be expanded evenly rapidly.Subsequently, the pulling plastic tab, the smooth working face of working edge slides on microslide, and it is even to form coating.Since with the microslide sliding contact be the smooth flat of plastic material, so coating evenly do not have cut, and is not easy pair cell formation mechanical damage.In addition, the cell smear preparing device adopts the process of " drawing " rather than " pushing away ", and operating process is simple, realizes easily.
Description of drawings
Do further detailed explanation below in conjunction with the accompanying drawing specific embodiments of the invention:
Fig. 1 is the schematic diagram of existing smear process.
Fig. 2 is the schematic diagram of smear process, and the sectional drawing of plastic tab of the present invention has been shown among the figure.
Fig. 3 is a structural representation of the present invention.
Fig. 4 is the partial enlarged drawing of Fig. 3.
Among the figure: 1 microslide, 2 push jacks, 3 drops of blood, 4 plastic tabs, 5 handles, 6 fixed mounts.
Embodiment
Fig. 3 shows one-piece construction of the present invention, and as can be seen from the figure, the cell smear preparing device comprises handle 5, fixed mount 6 and plastic tab 4, and plastic tab is fixed on the fixed mount.Inventive point of the present invention has been to adopt the plastic tab with a fixed structure; Therefore; Fig. 3 only shows a kind of concrete structure that adopts plastic tab of the present invention, need to prove that protection scope of the present invention is not limited in this embodiment; As long as adopted plastic tab, all should be covered by the claim scope and define in the category with this kind structure.Introduce plastic tab below in detail.
As shown in Figure 2, the bottom that at present defines plastic tab is the A limit, i.e. the bottom of plastic tab among Fig. 4.The A limit of this plastic tab has at smear and prepares in the process the smooth working face (being the lower inclined plane of plastic tab) with the microslide sliding contact; This working face and sheet thickness direction have angle; This A limit has the straight trough that extends along this edge direction, and straight trough is opened on the working face.
The working edge of plastic tab (being the A limit) has straight trough, prepares in the process at smear, when the cell drop on this working edge contact microslide, inhales principle according to hair, and cell liquid drops in the straight trough to be expanded evenly rapidly.Subsequently, the pulling plastic tab, the smooth working face of working edge slides on microslide, and it is even to form coating.Since with the microslide sliding contact be the smooth flat of plastic material, straight trough has formed cell drop storage capsule, in the smear process, making that coating is evener does not have cut, and is not easy pair cell formation mechanical damage.In addition, the cell smear preparing device adopts the process of " drawing " rather than " pushing away ", and operating process is simple, realizes easily.
Particularly, plastic tab 0.1～0.3mm is thick and have certain elasticity, when being under pressure, certain bending can be arranged.
For the angle with push jack and microslide adapts, said angle span: 45 °～60 °, guaranteed to prepare in the process angle with 30 °～45 ° of scopes of plastic tab integral body and microslide like this at smear.
Particularly, said straight trough opening is near the place, obtuse angle on said A limit.
Fig. 4 shows side structure of the present invention, and the A limit of plastic tab is under the naked state to be fixed on the plastic tab fixed mount.
In order can conveniently to use, the bending direction of said handle and said A limit acute angle point to roughly opposite, and this structure has guaranteed that the cell smear preparing device in use adopts the process of " drawing " rather than " pushing away ", and operating process is simple, realize easily.
Particularly, said plastic tab and fixed mount are one-body molded, and the relative edge on said A limit and fixed mount form connecting portion.
