Description
Technical field
Match liquid infusion apparatus the present invention relates to a kind of safe and convenient, belongs 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 201620402354.3 invention, which includes: that upper infusion is soft
Drop pot that pipe, lower infusion tube, its inlet and outlet are connected to upper infusion tube and lower infusion tube respectively is arranged in lower infusion
Medical fluid flow regulator on hose, furthermore, further includes: match liquid pot with what the drop pot was set side by side；The import of liquid pot is matched in connection
With the upper liquid separating pipe of the upper infusion tube；Lower separating tube of the connection with liquid pot outlet and the lower infusion tube；Setting is in institute
It states and matches liquid pot flow regulator with flow rate of liquid in liquid pot for adjusting on lower separating tube.Above-mentioned transfusion system structure is simple,
It is 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 with
Infusion apparatus reduces the waste of drug, mitigation, and does 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.
Summary of the invention
