Abstract
The utility model provides a preparing machine for a cell smear, which comprises a plastic slice, wherein a smooth working plane which is in slide contact with a glass slide during a preparation process of the cell smear is arranged at an A edge of the plastic slice; an inclined angle alpha is formed between the working plane and the thickness direction of the plastic slice; a straight flute which extends along the edge direction is arranged at the A edge; and an opening of the straight flute is arranged on the working plane. The working edge (namely, A edge) of the plastic slice is provided with the straight flute; during the preparation process of the cell smear, when the working edge is in contact with cell drop on the glass slide, the cell drop quickly and uniformly expands in the straight flute according to a capillary absorbing principle, and then the plastic slice is pulled and the smooth working plane at the working edge slides on the glass slide so as to form a uniform coating; the smooth plane made of a plastic material is in slide contact with the glass slide, so that the coating is uniform and free from scratch and the mechanical damage to the cell is difficult to form; besides, the process of pulling instead of pushing is adopted by the preparing machine for the cell smear; and the operation process is simple and is easily realized.
Description
Technical field
The utility model relates to the cell smear technical field, is 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 utility model will solve provides a kind of cell smear preparing device.
In order to solve the problems of the technologies described above, the technical scheme of the utility model 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
Below in conjunction with accompanying drawing the embodiment of the utility model is done further detailed explanation:
Fig. 1 is the schematic diagram of existing smear process.
Fig. 2 is the schematic diagram of smear process, and the sectional drawing of the utility model plastic tab has been shown among the figure.
Fig. 3 is the structural representation of the utility model.
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 the one-piece construction of the utility model, 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.The utility model point of the utility model has been to adopt the plastic tab with a fixed structure; Therefore; Fig. 3 only shows a kind of concrete structure that adopts the utility model plastic tab, need to prove that the protection domain of the utility model 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 the side structure of the utility model, 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.
