Description
Technical field
The present invention relates to a kind of transfusion device, more particularly, to one kind can automatically be vented, automatic liquid-stopping secondary filter medicine simultaneously
The disposable infusion set of the no adjacent benzene class plasticizer that liquid does not injure to human body again, belongs to medical instruments field.
Background technology
At present, disposable infusion set is the indispensable medical apparatus of clinical transfusion, and it typically includes from top to bottom successively
Puncture outfit, woven hose, drop cylinder, flow regulator, female Luer, transfusion needle.Though this transfusion device structure is simple, in transfusion
If at the end of extract transfusion needle or carry out in time not in time and change bottle operation, air will enter infusion pipeline and form bubble, bubble
Enter and can cause vein blood back in the patient, or even lead to serious medical accident.This requires that medical personnel's repeat runs in-motion viewing is examined,
Virtually increased stress and the work difficulty of patient, entourage and medical personnel.
And, with scientific and technological development, the cognitive lifting of people, gradually recognize in infusion process that having particulate exists,
And harm can not be produced by body metabolism.Because the capillary diameter in human body averagely only has 7um～9um, minimum is
4um.If patient often infuses, in liquid, the particulate more than 4um for the diameter will be accumulated in the heart, liver, lung, brain, kidney, muscle, skin
In the capillaries such as skin, larger particulate can directly contribute capillary embolism, cause local blood supply insufficiency, histanoxia and lead
Cause oedema and inflammation, less particulate may be eaten by macrophage, cause macrophage to increase, form granuloma.These become
Change can occur especially in lungs in body tissue.
Additionally, particulate also can directly cause exothermic reaction.At present in infusion process, infusion reaction happens occasionally, except thin
Outside bacterium pollution reaction, pyrogen reaction, the particulate pollution reaction that particulate matter causes also increasingly is subject to people's attention.
Existing transfusion device is typically all to be fabricated by using transparent material, and such as, vinyon, using transparent material
Material makes transfusion device purpose and is to observe the liquid situation in woven hose in infusion process at any time.But in clinical treatment,
Some medicines can decompose after seeing light and lose drug effect it is necessary to carry out lucifuge drip-feed, for this frequently with lucifuge paper or black cloth bar
It is rolled on woven hose and carry out lucifuge process.But due to woven hose longer and also soft it is not easy to lucifuge paper or black cloth cover
Obtain tightly seamless, photophobism is not fine, not only encapsulation process troublesome poeration, and uses very inconvenient, due to transfusion
Pipe is blocked paper or black cloth is wound around the flow that cannot observe medicine, and drug flux is unadjustable.
For this reason, have patented technology to be disclosed in woven hose direct interpolation light absorbent, but such situation light absorbent can
Can react with liquid, affect infusion safety, and extinction adds the bad problem of generally existing translucency after light absorbent, visually
Property is poor.In order to prevent light absorbent from reacting with liquid, document is had to overcome this difficult using the method for double-deck woven hose, defeated
Liquid pipe internal layer still adopts common woven hose, one layer of outer layer with light absorbent or UV absorbers of outer wrap, though this
So solve the problems, such as that light absorbent is reacted with liquid, but be because that refraction angle is different, using the permeability leading to woven hose more
Difference, if or even cannot differentiate whether there is bubble in woven hose it is well known that in air input human vas, being good for the person
Health can impact.If so making transfusion device both lucifuges, have certain transparency again, prevent medicine from reacting with lucifuge material is again
Problem demanding prompt solution.
Content of the invention
It is an object of the invention to provide a kind of secondary filter light proofing infusion apparatus, its both lucifuge, there is certain transparency again, and
Prevent medicine from reacting with lucifuge material.
For achieving the above object, present invention employs following technical proposals.A kind of secondary filter light proofing infusion apparatus, including wearing
