Description
Technical field
The utility model belongs to field of plant tissue culture, and in particular to a kind of paraffin section air extractor.
Background technology
Paraffin section method of tableting is most widely used method in histology conven tional tabletting techniques, and is cut into slices in making
Cheng Zhong, fixation is mostly important step, outstanding Histological section be built upon appropriate and complete immobilizing foundation it
On.Fixation can make to be organized in the morphosis of holding cell in paraffin section manufacturing process, the original shape for being allowed to and surviving
State is similar with structure without deforming.If tissue is not fixed thorough, section occurs " ash dye " or " turning white " phenomenon.Gu if
Fixed bad, then any stage of film-making can not all be remedied afterwards.
During the vegetable material film-making such as bud, stem section, because internal space between cells is larger, there is air, fixer is not
Easily enter, so the air in material need to be extracted out.At present, conventional method includes vacuum desiccator band motor degassing method and pin
Cylinder degassing method.But, vacuum desiccator band motor degassing method has to last to be grown, easily causes air pollution, and open pumping, fixer
Volatile shortcoming；And syringe degassing method fixer easily causes pollution, pumping effect is general.
The content of the invention
It is good that the purpose of this utility model is to provide a kind of simple to operate, pumping effect, can take out rapidly material in most plant,
Rapidly permeate into fixer, safety, economical and practical paraffin section air extractor.
The utility model is practiced by the following technical programs：
Paraffin section air extractor of the present utility model, it is characterised in that including the push rod in syringe, syringe needle, syringe,
Described syringe front end is provided with syringe needle fixing port, and described syringe needle is installed on syringe needle fixing port, and described push rod front end is provided with
Rubber base, described rubber base is adapted realization and is tightly connected with syringe internal diameter, and a pressure is provided with the push rod after rubber base
Button, is provided with a round on the syringe of the position corresponding with clinching, and described clinching includes " convex " shape fixture block, spring and spring
Mounting groove, inside push rod, the lower end of described spring is mounted in spring mounting groove described spring mounting groove, bullet
The upper end of spring is fixed in " convex " shape fixture block, is provided with opening on the push rod side wall of " convex " shape fixture block correspondence position, opening it is big
The small protuberance size with " convex " shape fixture block is adapted, so that " convex " shape fixture block is stuck in opening, described " convex " shape fixture block
It is adapted with hole in coordinating the protuberance for enabling " convex " shape fixture block to snap in hole.
It is preferred that, it is provided with push rod tail in the end of push rod.
The utility model is so to use：
Push rod is first pushed into lowermost end, syringe needle then is installed on the syringe needle fixing port of syringe；Syringe needle is passed through into rubber stopper
Insertion notices that syringe needle can not be inserted into fixer equipped with fixer and material penicillin bottle；Syringe is extracted outward to suitable
Position, the protuberance of " convex " shape fixture block is snapped in corresponding hole and fixes push rod, and paraffin section air extractor is passed through into push rod
Syringe needle when vegetable material does not have bubble to emerge, is extracted bottle by head suspension on shelf, and " convex " shape fixture block is then pressed again
Protuberance, lowermost end is pushed into by push rod；Repetition is pulled out and is pumped through journey 2~3 times, until the completely no bubble of material is emerged.
The utility model has the advantage of：Paraffin section air extractor is simple to operate, and pumping effect is good, can rapidly take out most plant
Material in object, rapidly permeate into fixer, safety is economical and practical.

Specific embodiment：
Following examples are further illustrated to of the present utility model, rather than to limitation of the present utility model.
Embodiment 1：
As shown in figure 1, the push rod 4 in the paraffin section air extractor of the present embodiment, including syringe 1, syringe needle 3, syringe,
Described syringe front end is provided with syringe needle fixing port 2, and described syringe needle 3 is installed on syringe needle fixing port 2, and described push rod front end sets
There is rubber base 5, described rubber base 5 is adapted realization and is tightly connected with the internal diameter of syringe 1, and one is provided with the push rod after rubber base
Individual clinching 7, is provided with a round 8,8-1,8-2,8-3,8-4, described clinching bag on the syringe of the position corresponding with clinching
" convex " shape fixture block 11, spring 10 and spring mounting groove 9 are included, described spring mounting groove 9 is located inside push rod 4, described spring
Lower end be mounted in spring mounting groove 9, the upper end of spring is fixed in " convex " shape fixture block 11, " convex " shape fixture block correspondence
