Description
Technical field
The utility model relates to a kind of filterings of safe and convenient to match liquid infusion apparatus, belong to field of medical products.
Background technique
Infusion apparatus is that a kind of dosage is big, is ceased using wide Dispoable medical utensil, and with our daily life
Correlation, infusion sometimes, which needs to mix different drugs, is defeated by patient, however some drugs cannot mix for a long time, can only
It mixes and reuses before infusion, progress drug hybrid manipulation is more troublesome before infusion, is unfavorable for emergency rescue.
Application No. is a kind of infusion apparatus is disclosed in the utility model of 201620402354 .3, which includes: upper defeated
Drop pot that liquid hose, lower infusion tube, its inlet and outlet are connected to upper infusion tube and lower infusion tube respectively is arranged under
Medical fluid flow regulator on infusion tube, furthermore, further includes: match liquid pot with what the drop pot was set side by side；Liquid pot is matched in connection
The upper liquid separating pipe of import and the upper infusion tube；Lower separating tube of the connection with liquid pot outlet and the lower infusion tube；Setting
Match liquid pot flow regulator with flow rate of liquid in liquid pot for adjusting on the lower separating tube.Above-mentioned transfusion system structure letter
It is single, easy to use, compatibility can be carried out by dosing object at any time, and when the change after compatibility occurs, can only throw away seldom liquid
Body and infusion apparatus reduce the waste of drug, mitigation, and do not have to replacement infusion apparatus and liquid.
But there are still some disadvantages for above-mentioned infusion apparatus.For example, above-mentioned infusion apparatus is when in use, it is by the first medical fluid
Drop pot is respectively put into second of medical fluid and is matched in chamber pot with what drop pot was set side by side, then by on pipeline below liquid pot
Derailing switch controls the input quantity of second of medical fluid, and in above-mentioned infusion apparatus, two kinds of medical fluids are directly to mix in perfusion tube, are not had
There is the special mixer of setting, mixed effect is unsatisfactory, and the proportion of two kinds of medical fluids is also not easy strict control.
In addition, needle-covering cap in the prior art and infusion niidl are mating, and during using infusion apparatus, syringe needle
It after helmet is removed from infusion niidl, is often dropped, pollutes environment；And make infusion apparatus after infusion is completed, infusion
Syringe needle can not be valid protected, and infusion niidl is exposed to be easy to damage medical worker outside.
In addition, due to there are a large amount of various particles in medical fluid, so infusion apparatus is designed with liquid medicine filter.It is general defeated
The particle of 20 microns of liquid medicine filter intelligent filtering diameter or more used in liquid device, filter membrane used are coarse filtration film.And medicine
There are 5~20 microns of diameter of particle number is most in liquid, harm is maximum.Therefore, with 5 microns of filter diameter of energy or more
The infusion apparatus of micro particle filtering film is known as precision filter infusion set, but the filter opening very little of secondary filter, influences the flow and stream of infusion
Speed.
