Description
Technical field
The utility model belongs to medical teaching mode manufacture technology field, and in particular to a kind of permanent teaching micro-capsule mark
This film.
Background technology
Microencapsulation（Abbreviation micro-capsule）It is a kind of novel form to grow up the 1960s.After medicine preparation is at micro-capsule
With cover drug bad smell, increase medicine stability, reduce volatile ingredient loss, make liquid medicine solidification,
The advantages that rate of release of drug can effectively be controlled, especially in recent years be used for anticancer drug preparation, can make drug accumulation in
The target areas such as liver or lung, reduce its toxic side effect at the effect of improving drug.So in the pharmacy and relevant speciality medicine of medical college
In agent course, micro-capsule is the knowledge point that student must be learned by and grasp, but since this dosage form is a kind of microscopic, spherical capsule
Body（Diameter is at 1 ~ 250 μm）, including drug（Capsule-core）With capsule material two parts of packaging medicine, only can just see under the microscope
Understand its structure, if can refer to without material object in experimental teaching, it is micro- that student can not judge whether self-made product forms
Capsule.But currently, permanently there is also problems for the making and preservation of teaching micro-capsule sample slice.
In permanent teaching in the preservation of micro-capsule sample slice, the entrance of air and the exudation of glycerine make slide be easy quilt
Microbial contamination in air and go mouldy, cause micro-capsule sample that cannot preserve for a long time.And for permanently teaching with slide come
Say, can long-term preservation be only key, but each relevant environmental conditions and other factors are to Saving specimen during Saving specimen
Influence it is huge, first, environmental factor：Impurity, dust, acid, alkali, the content of salt substance and temperature in such as air, humidity,
The variation of the factors such as illumination may all make sample be damaged；Second, biological factor：The microorganisms such as moth, bacterium, mould spread out
It is damaged caused by raw etc.；Third, human factor：In use due to keeping, carry when caused by damage or preservation and
Damage caused by servicing operations are lack of standardization, more also the incorrect method when school microscope is observed leads to slide sample
Damage.Especially teaching slide, because frequency of use is high, students' experiences are shallow, are easily stained with examination on slide in use
Agent, water, dust etc., service life is short；And operated by student, it is easy integrally to pollute the slide box for placing slide, loss is tight
Weight.
For above problem, a kind of permanent teaching micro-capsule sample slice is developed, the intuitive of teaching is not only increased, and
And can long-term preservation, be very important.

Cystoblast, band, the microcapsule layer are arranged on glass slide, and the top of microcapsule layer covers the first coverslip, and described the
It is bonded by neutral gum between one coverslip and the second coverslip, second coverslip is more than the first coverslip,
The glass slide is more than the second coverslip, and the band includes that setting is used for the second coverslip in the second coverslip surrounding
The band sealed between glass slide, the micro-capsule sample slice ontology are placed in transparent vacuum container.The utility model
The permanent teaching micro-capsule sample slice provided, not only effectively increases the intuitive of teaching, improves the quality of teaching, and this reality
It is simple in structure with novel sample slice, can long-term preservation, efficiently solve existing slide easily go mouldy, rapid wear in teaching process
The problem of consumption.
Compared with prior art, the utility model has the following technical effects：
1, the utility model provides a kind of permanent teaching micro-capsule sample slice, not only effectively increases the intuitive of teaching
Property, improves the quality of teaching, and the sample slice of the utility model is simple in structure, can long-term preservation, efficiently solve existing
The problem of slide easily goes mouldy, is easily lost in teaching process.
2, the sample slice of the utility model does not interfere with microscopical observation not only, at the same it is possible to prevent air from entering and
The exudation of glycerine ensures that micro-capsule sample can preserve for a long time, is not gone mouldy by the microbial contamination in air.
3, the setting of the utility model transparent vacuum container has been inherently eliminated pollutant, mould and sky in air
Temperature and moisture etc. is influenced caused by sample slice, and can be used as protective layer, is avoided taking, is carried the damage caused by slide
It is bad, it is most important that, it can directly be observed, be taken out without from vacuum environment, easy to use, it is lasting to preserve.
4, the utility model can observe the vacuum degree in transparent vacuum container at any time by the vacuum meter of setting, be convenient for glass
The management of piece can also observe leakproofness at any time, when there is the case where poor sealing, convenient for finding and handling in time.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
In figure：1- glass slides, the first coverslips of 2-, the second coverslips of 3-, 4- microcapsule layers, 5- bands.
Specific implementation mode
The utility model will be further described below with reference to the accompanying drawings, but is not subject in any way to the utility model
Limitation is transformed or replaced based on any made by the utility model introduction, belongs to the scope of protection of the utility model.
The utility model as shown in Fig. 1 includes micro-capsule sample slice ontology and transparent vacuum container, the micro-capsule sample
Piece ontology includes glass slide 1, the first coverslip 2, the second coverslip 3, microcapsule layer 4, band 5, and the microcapsule layer 4 setting exists
On glass slide 1, and the top of microcapsule layer 4 covers the first coverslip 2, leads between first coverslip 2 and the second coverslip 3
It crosses neutral gum to be bonded, second coverslip 3 is more than the first coverslip 2, and the glass slide 1 is more than the second lid glass
Piece 3, the band 5 include being arranged to be used to seal between the second coverslip 3 and glass slide 1 in 3 surrounding of the second coverslip
Band, the micro-capsule sample slice ontology are placed in transparent vacuum container.
The microcapsule layer 4 is liquid paraffin microcapsule layer.
The specification of first coverslip 2 is 18mm × 18mm, and the specification of the second coverslip 3 is 20mm × 20mm；Institute
The specification for the first coverslip 2 stated is 20mm × 20mm, and the specification of the second coverslip 3 is 22mm × 22mm.
The band 5 further includes that setting is used in 2 surrounding of the first coverslip between the first coverslip 2 and glass slide 1
The band of sealing.
The band 5 is transparent neutral glass cement band.
The transparent vacuum container is transparent vacuum bag.
The transparent vacuum container be transparent glass vacuum box, the transparent glass vacuum box include glass cartridge and
