Description
Technical field
The utility model belongs to technical field of medicine, more particularly to a kind of small-scale injection impurity fast filtering
Device.
Background technology
" visible foreign matters " in injection refer to：The insoluble substance that can visually observe under prescribed conditions, grain
Diameter or length are typically larger than 50 μm, and majority is caused by cleaning container is not thorough, medical filtration is bad, and there are also be degradation production
Object, between drug or auxiliary material reaction product or with packaging material reaction product, packaging material cast etc..
Injection is the highest preparation of quality requirement in all formulations dosage form, it is seen that foreign matter is in injection is especially infused
Foreign matter particle caused by endanger pay attention to day by day.Particle is larger or local vascular blocking can excessively be caused to cause thrombus, so that for
Blood is insufficient or oedema or phlebitis are generated because of anoxic, and allergy and heat source sample is caused to be reacted, and therefore, strictly controls injection
Clarity is particularly significant.
Prepared by small-scale injection for laboratory, when especially preparing traditional Chinese medicine injection, is needed with the method mistake filtered
Filter out the impurity and visible foreign matters in injection.But since filter membrane hole is smaller, filter membrane is easy to block during filtering, shadow
It rings and filters efficiency, and be also easy to produce traditional Chinese medicine ingredients loss.
Utility model content
Purpose of the utility model is to solve laboratories in the prior art to prepare existing for small-scale injection suction filtration
Problem provides a kind of small-scale injection impurity rapid filtering device.The device can efficient, quick filtering liquid medicine,
And component damages in liquid can be reduced.
A kind of small-scale injection impurity rapid filtering device, including filter element, suction filtration unit and fixed cell group
At the filter element is connect with the suction filtration unit, and the fixed cell is connect with the filter element；
Wherein, the filter element is located at top by the top cylinder shape funnel with liquid inlet conduit positioned at the top
Macropore filter membrane below cylindrical shape funnel, the middle part cylindrical shape funnel being located at below macropore filter membrane are located at middle part cylindrical shape funnel
The mesoporous filter membrane of lower section, the lower cylindrical funnel being located at below mesoporous filter membrane, the aperture being located at below lower cylindrical funnel
Filter membrane is located at the sand core filter below aperture filter membrane and the injection receiving flask below sand core filter.
Further, the suction filtration unit is vacuum pump, and vacuum pump is connect by pipeline with the sand core filter.
Further, the fixed cell is iron stand, sets that there are four flask holders to justify respectively with the top on iron stand
Tubular funnel, middle part cylindrical shape funnel, lower cylindrical funnel are connected with sand core filter.
Further, the upper and lower opening of the top cylinder shape funnel, middle part cylindrical shape funnel upper and lower opening, lower cylindrical leakage
The upper and lower opening that struggles against is identical with the back cut diameter of sand core filter.
Further, the filter sizes of the macropore filter membrane, mesoporous filter membrane and aperture filter membrane are sequentially reduced.
Further, the sand core filter carries frosted mouth.
Further, the lower mouth of the sand core filter matches with the bottleneck of the injection receiving flask.
Further, the injection receiving flask is equipped with leakage fluid dram.
Further, the liquid inlet conduit is connect with injection to be filtered.
Compared with prior art, the advantage of the utility model is：
1, utility model device is small, can operate in superclean bench, avoids injection contaminated；
2, the utility model can be blocked using three layer filtration device to avoid filter membrane when filtering, improve separative efficiency height, also
Component damages in liquid can be reduced.

Specific implementation mode
Embodiment 1
A kind of small-scale injection impurity rapid filtering device, including filter element, suction filtration unit and fixed cell group
At；The filter element is located at top cylinder shape and is leaked by the top cylinder shape funnel 2 with liquid inlet conduit 1 positioned at the top
The macropore filter membrane 3 of 2 lower section of bucket, is located at the middle part cylindrical shape funnel 4 of 3 lower section of macropore filter membrane, is located at 4 lower section of middle part cylindrical shape funnel
Mesoporous filter membrane 5, be located at the lower cylindrical funnel 6 of the lower section of mesoporous filter membrane 5, be located at the aperture of 6 lower section of lower cylindrical funnel
Filter membrane 7 is located at the sand core filter 8 with frosted mouth of the lower section of aperture filter membrane 7 and positioned at 8 lower section of sand core filter equipped with leakage fluid dram
Injection receiving flask 9；The suction filtration unit is vacuum pump 10, and vacuum pump 10 is connect by pipeline with the sand core filter 8；Institute
It is iron stand 11 to state fixed cell, set on iron stand 11 there are four flask holder 12 respectively with the top cylinder shape funnel 2, middle part
Cylindrical shape funnel 4, lower cylindrical funnel 6 and sand core filter 8 connect；
Wherein, the upper and lower opening of the top cylinder shape funnel 2,4 upper and lower opening of middle part cylindrical shape funnel, lower cylindrical funnel
