Description
Technical field
The present invention relates to field of medical device, particularly a kind of barrier film transfusion machine.
Background technology
Venous transfusion is a kind of administering mode conventional in clinical treatment, according to character, the difference of patient's body constitution of medicine,
Speed of intravenous infusion is the most different.Infuse too fast, cross all be difficult to reach intended therapeutic effect slowly, even affect nursing safety.
It is poor that traditional infusion model transfusion speed controls, and needs infusion bottle or transfusion bag are hung height, during transfusion when transfusion
Inconvenient patient moves, and in the ambulance that space is less, also infusion bottle or transfusion bag are hung height by inconvenience；And existing transfusion
Pump be not selling at exorbitant prices be exactly that infusion pump has the strongest pulse, stronger pulse that patient infusion can be made uncomfortable；And in disease
When people infuses, in particularly winter, the ice-cold medicinal liquid of temperature makes patient feel cold especially, feels the most uncomfortable；Traditional
During the transfusion of transfusion machine, it is likely to be due to the friction of rotating shaft and sealing member and makes to come off on rotating shaft or sealing member and pollute medicinal liquid.
Summary of the invention
For the above-mentioned existing issue existed at patient infusion, the technical purpose of the present invention is that offer one can be automatic
Control, the most do not have the friction of sealing member and come off chip and pollute medicinal liquid, the barrier film transfusion machine of damping of not infusing.
