Abstract
The utility model discloses a phthalate-free precise filtering infusion apparatus which comprises an infusion tube, a puncture outfit, a drip tube, a flow regulator, a filter, a Luer taper and an infusion needle. The puncture outfit, the drip tube, the flow regulator, the filter, the Luer taper and the infusion needle are sequentially connected with the infusion tube. A liquid check cavity is formed in the filter and is provided with a filtering membrane. A vent hole is formed in the side wall of the filter, a first catheter communicated with the liquid check cavity and extending upwards is arranged on the side portion of the filter, a second catheter communicated with the liquid check cavity and extending downwards is arranged on the other side portion of the filter, and the height of a liquid outlet of the second catheter is not lower than that of a liquid inlet of the first catheter. By the arrangement, air entering an infusion channel can be effectively removed, and liquid can stop flowing automatically to prevent blood return; meanwhile, particles in liquid medicine can be effectively filtered out, and blood clot caused by the fact that the particles circulate with blood can be reduced; in addition, phthalate-free acetyl tributyl citrate is adopted to plasticizer of the infusion tube which is enabled to be safer to human body.
Description
Technical field
The present invention relates to a kind of disposable infusion set, relate in particular to a kind of can automatic vent, automatic liquid-stopping secondary filter simultaneously medicinal liquid to the human body disposable infusion set without adjacent benzene class plasticizer of injury not, belongs to medical instruments field again.
Background technology
At present, disposable infusion set is the medical apparatus of clinical transfusion indispensability, and it generally comprises perforator, tube for transfusion, drop cylinder, flow regulator, female Luer, transfusion needle from top to bottom successively.Though this transfusion device is simple in structure, if extract not in time transfusion needle or change in time bottle operation when transfusion finishes, air will enter infusion pipeline and form bubble, and bubble enters in patient body can cause vein blood back, even leads to serious malpractice.This will ask medical personnel's repeat runs in-motion viewing to examine, and virtually increase patient, entourage and medical personnel's stress and work difficulty.
And along with scientific and technological development, the lifting of people's cognition, recognizes that gradually having microgranule in infusion process exists, and can not be produced harm by body metabolism.Because the blood capillary diameter in human body on average only has 7um～9um, that minimum is 4um.If patient often infuses, in medicinal liquid, diameter will be accumulated in the blood capillaries such as the heart, liver, lung, brain, kidney, muscle, skin over the microgranule of 4um, larger microgranule can directly cause capillary embolism, cause local blood supply insufficiency, histanoxia and cause edema and inflammation, less microgranule may be eaten by macrophage, cause macrophage to increase, form granuloma.In these variation Ke body tissue, especially lungs, occur.
In addition, microgranule also can directly cause exothermic reaction.In infusion process, infusion reaction happens occasionally at present, and except germ contamination reaction, pyrogen reaction, the particle contamination reaction that particulate matter causes is also more and more subject to people's attention.
In addition, phthalate plasticiser in traditional infusion pipe manufacturer material (vehicle economy HP) or dioctyl phthalate (being called for short DOP), can have the carcinogenic harm of Denging to human body.
Summary of the invention
In order to solve above-mentioned the problems of the prior art, the object of this invention is to provide a kind of can automatic vent, automatic liquid-stopping secondary filter simultaneously medicinal liquid is again to the human body transfusion device without adjacent benzene class plasticizer of injury not.
To achieve these goals, the technical solution used in the present invention is:
A kind of without adjacent benzene precision filter infusion set, comprise tube for transfusion and be set in the flow regulator on described tube for transfusion, on described tube for transfusion, also connect and be connected with perforator, drop cylinder, female Luer and transfusion needle in turn, it is characterized in that: between described flow regulator and female Luer, be also provided with a filter, in described filter, form one and stop sap cavity, described stopping in sap cavity is provided with filter membrane;
On one sidewall of described filter, be provided with a steam vent, one sidepiece of described filter be provided with one with the first conduit protruding upward that only sap cavity is connected, the other side of described filter be provided with one with the second conduit stretching out downwards that only sap cavity is communicated with, the liquid outlet height of described the second conduit is not less than the inlet height of the first conduit.
Related content in technique scheme is explained as follows:
1. in such scheme, described filter is disc structure, can effectively remove the air that enters into infusion pipeline, assurance does not have air to enter human vas, in infusion bottle during without medicinal liquid, the medicinal liquid of the filter of flowing through can stop flowing automatically, prevents from causing blood back simultaneously.
2. in such scheme, another inside sidewalls of described filter is provided with a plurality of guiding gutters.The setting of guiding gutter can be so that the medicinal liquid being filtered in filter flows out through the second conduit rapidly and uniformly.
3. in such scheme, the material of described filter membrane is polyethersulfone resin.Filter membrane is the microgranule more than 2um in filtering medicinal liquid effectively, reduces and with blood circulation, causes thrombosis, even more serious circulatory disturbance because of microgranule.
4. in such scheme, described tube for transfusion and described drop cylinder all adopt the pvc material that the positive tributyl of acetyl tributyl citrate is plasticiser to make, containing phthalic acid ester composition and benzene ring substance, unsafer to human body.
5. in such scheme, described tube for transfusion and drop cylinder, filter are and are tightly connected, and guarantee air-tightness and the safety of whole infusion pipeline.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
The present invention compared with prior art, increased the precision liquid medicine filter of air separation, intelligent aerofluxus and automatic liquid-stopping function, can effectively remove the air that enters into infusion pipeline, assurance does not have air to enter human vas, simultaneously in infusion bottle during without medicinal liquid, the medicinal liquid of filter of flowing through can stop flowing automatically, prevents from causing blood back, to patient, brings injury; Effective the microgranule more than 2um in filtering medicinal liquid simultaneously, minimizing causes thrombosis with blood circulation because of microgranule, or because erythrocyte aggregation forms thrombosis and phlebitis, even more serious circulatory disturbance on microgranule foreign body; In addition, on the plasticizer of the tube for transfusion contacting at medicinal liquid, adopt the positive tributyl of acetyl tributyl citrate (being called for short ATBC) of non-adjacent benzene class, and containing phthalic acid ester composition and benzene ring substance, make it to human body safety.The present invention is applicable to medical institutions' infusion medicinal liquid clinically, the patient who especially injection quality is had higher requirements.
