Description
Technical field
This utility model relates to the aseptic medical equipment that is used for the clinical transfusion purposes, especially relate to a kind of heliosensitivity medicinal liquid that is used to instil from aerofluxus MULTILAYER COMPOSITE type light proofing infusion apparatus.
Background technology
At present; The general infusion set that medical field is commonly used comprises perforator protective sleeve, bottle plug puncture unit, air filter, dropper, dropping funnel lid, liquid injecting piece, dropping funnel, flow regulator, liquid medicine filter, transfusion needle stand and transfusion faller gill; And through transfusion catheter they are linked together, above-mentioned most of parts are processed by transparent pvc material.
When just having begun, medicinal liquid flows out from dropper general infusion set in transfusion, gets in the dropping funnel, and liquid is prone to the gas in the dropping funnel discharged downwards and forms in the transfusion catheter that gas-liquid mixture gets into the dropping funnel below and produce bubble.Simultaneously, because of the surface tension effects of transfusion catheter inwall, the inwall of transfusion catheter is prone to a spot of bubble of absorption, and it is comparatively difficult, time-consuming and loaded down with trivial details to get rid of consequent bubble process, if the bubble that is produced gets in patient's body, is prone to cause harm such as aeroembolism.So medical personnel must be artificial with the emptying as much as possible of the bubble in the transfusion catheter before infusing; Common artificial deflated method is: bottle plug puncture unit is inserted in the infusion bottle, hand over the dropping funnel reversal of the natural order of things earlier, be both with hands and squeeze dropping funnel; Medicinal liquid is got in the dropping funnel, treat that certain amount of fluid is full of dropping funnel after, put down dropping funnel; Just maybe most bubble be got rid of, the process of this artificial aerofluxus bubble is loaded down with trivial details time-consuming again, is unfavorable for promptly infusing and giving emergency treatment to a patient.Simultaneously, for some must lucifuge the medicine of transfusion, clinical when using this medicine transfusion; Need add native silver or black cloth or black bag whole transfusion catheter is wrapped up, cause very big trouble to medical personnel, simultaneously; If have accidentally, just be prone to cause drug effect to descend, lost efficacy even go bad.
Be directed to this, at present special light proofing infusion apparatus arranged also on the market, mainly be used for drip transfusion to the heliosensitivity medicine clinically, prevent that the infusion process herb liquid from decomposing under ultraviolet irradiation.Yet; Existing light proofing infusion apparatus generally is directly to increase the lucifuge agent in the material the inside; Reach the effect of lucifuge, the lucifuge agent very easily comes off under the effect of medicinal liquid (particularly acid or alkaline medicinal liquid) or other reaction takes place, and causes light proofing infusion apparatus dangerous.
Summary of the invention
But the purpose of this utility model be to provide a kind of both can effectively prevent bubble produce and prevent bubble get in the transfusion catheter, simultaneously also lucifuge prevent medicine contact with the lucifuge composition, safe and reliable, easy and simple to handle from aerofluxus MULTILAYER COMPOSITE type light proofing infusion apparatus.
The purpose of this utility model is achieved in that
A kind of from aerofluxus MULTILAYER COMPOSITE type light proofing infusion apparatus; Comprise perforator protective sleeve, bottle plug puncture unit, last air filter, dropping funnel lid, liquid injecting piece, dropping funnel, dropper, flow regulator, liquid medicine filter, transfusion needle stand and transfusion faller gill; And they are linked together through transfusion catheter; Characteristic is: cover at dropping funnel the automatic vent assembly of being made up of exhaust needle and following air filter is installed, in exhaust needle, be provided with the endoporus of a perforation, can supply circulation of air; Exhaust needle passes dropping funnel lid and stretches in the dropping funnel and press close to the inwall at dropping funnel, and the terminal vertical dimension of the end of exhaust needle and dropper is 10mm～25mm; Following air filter is installed in the upper end of dropping funnel lid and links with exhaust needle, is provided with in the infra air filter and can filters the air filtration film that gets into air in the dropping funnel.The structure that the automatic vent assembly is such can be discharged the air in the dropping funnel during transfusion automatically through gas deflation assembly, can effectively prevent the generation of bubble and prevent that bubble from getting in the transfusion catheter of dropping funnel below.
Transfusion catheter, dropping funnel and liquid medicine filter are by transparent internal layer and the outer compound formation of lucifuge; Perhaps, transfusion catheter, dropping funnel and liquid medicine filter are by transparent internal layer, transparent outer layer be positioned over the compound formation in lucifuge intermediate layer between transparent internal layer and the transparent outer layer.
Transparent internal layer, transparent outer layer are processed by the medical grade plastics, and lucifuge skin or lucifuge intermediate layer are processed by opaque lucifuge plastics.
This utility model has been set up the automatic vent assembly with ability automatic vent function on the basis that is traditional disposable infusion set.This utility model is the same with the transfusion set operating procedure in use, does not change operator's use habit, also can reduce the loaded down with trivial details step that manual work squeezes dropping funnel, aerofluxus bubble.When this utility model uses, confirm that earlier whether the automatic vent component holes is opened, and closes flow regulator; Again bottle plug puncture unit is inserted in the infusion vessel, do not need to squeeze dropping funnel, need not hang upside down dropping funnel with hands; Medicinal liquid can get in the dropping funnel automatically, and the medicinal liquid liquid level constantly rises, and rising to exhaust needle terminal position height should no longer rise always; Medicinal liquid stops to flow, and in this process, the air in the dropping funnel is all discharged through gas deflation assembly; No bubble is sneaked in the whole communication path, thereby effectively prevents the bubble generation and prevent to get in the transfusion catheter; Open flow regulator, medicinal liquid begins to flow and be full of whole transfusion catheter, up to from the transfusion faller gill, flowing out, closes flow regulator, gets into transfusion by routine puncture vein.This utility model can solve existing transfusion device infusion process because of aerofluxus bubble work loaded down with trivial details, lose time, increase safety guarantee simultaneously, reduce in infusion process getting into the worry that human body causes adverse consequencess such as aeroembolism because of gas.
Simultaneously, this utility model is processed owing to each parts that contacts with medicinal liquid are the medical grade plastics, can not react with medicinal liquid.Lucifuge skin or lucifuge intermediate layer are that black or opaque lucifuge plastics such as brown are processed, and have the lucifuge effect, can reach the lucifuge effect to the requirement of heliosensitivity medicine.
Therefore; Both can prevent effectively that bubble from producing and prevent that bubble from getting in the transfusion catheter, also lucifuge prevents that medicine from contacting with the lucifuge composition, safe and reliable, advantages of simple operation simultaneously but the utlity model has; It has avoided contacting of medicinal liquid and lucifuge composition fully; Improve medical personnel's work efficiency effectively, and strengthened the infusion treatment effect.
