Abstract
The invention relates to a sterile medical appliance for clinical transfusion, in particular to an automatic exhaust transfusion system. The automatic exhaust transfusion system comprises a bottle cork puncture outfit protective casing, a bottle cork puncture outfit, a short transfusion catheter, a short exhaust catheter, an air filter, a dropping funnel cover, an automatic exhaust component, a liquid medicament injection element, a dropping funnel, a flow rate adjuster, a long transfusion catheter, a liquid medicament filter and a disposable intravenous infusion needle, wherein the automatic exhaust component is arranged on the dropping funnel cover and consists of an exhaust needle and the air filter; the exhaust needle runs through the dropping funnel cover to cling to the inner wall of the dropping funnel and be extended into the dropping funnel; the air filter is arranged at the upper end of the dropping funnel cover and is linked with the exhaust needle; and an air filter membrane is arranged in the air filter. The automatic exhaust transfusion system can effectively prevent bubbles from being produced and entering the transfusion catheters, and has the characteristics of simple structure, safety and reliability.
Description
Technical field
The present invention relates to be used for the aseptic medical equipment of clinical transfusion purposes, especially relate to a kind of automatic-exhaust transfusion device.
Background technology
At present, the general infusion set that medical field is commonly used constitutes by parts such as bottle plug puncture unit protective sleeve, bottle plug puncture unit, transfusion tubulature, aerofluxus tubulature, air filter, last dropper, dropping funnel, flow regulator, transfusion long duct, liquid medicine filter and disposable use venoclysis needles.When general infusion set has just begun in transfusion, medicinal liquid flows out from dropper by pipeline, enter dropping funnel, liquid is easily discharged the gas in the dropping funnel downwards the formation gas-liquid mixture and is entered in the long transfusion catheter, therefore produces bubble, simultaneously, because of the surface tension effects of transfusion catheter inwall, the inwall of transfusion catheter is a spot of bubble of absorption easily, 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 enters in patient's body, easily cause harm such as aeroembolism.So, medical personnel must be artificial with the emptying as much as possible of the bubble in the catheter of transfusion system before infusing, and common artificial deflated method is: after bottle plug puncture unit is inserted transfusion bottle stopper, earlier dropping funnel is hung upside down, squeeze dropping funnel with hands simultaneously, medicinal liquid entered in the dropping funnel, treat that certain amount of fluid is full of dropping funnel after, put down dropping funnel, just most bubble may 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.
Summary of the invention
The object of the present invention is to provide a kind of can automatic vent in infusion process, can prevent effectively that bubble from producing and prevent that bubble from entering interior, simple in structure, the safe and reliable transfusion device of transfusion catheter.
The object of the present invention is achieved like this: the present invention includes bottle plug puncture unit protective sleeve, bottle plug puncture unit, transfusion tubulature, aerofluxus tubulature, air filter, dropping funnel lid, automatic vent assembly, liquid injecting piece, dropping funnel, flow regulator, transfusion long duct, liquid medicine filter and disposable use venoclysis needle.Cover at dropping funnel the automatic vent assembly is installed; The automatic vent assembly is made up of an exhaust needle, an air filter.Exhaust needle passes dropping funnel lid and is close to the dropping funnel inwall and stretches in the dropping funnel; Air filter is installed in dropping funnel and covers end and link with exhaust needle, and the air filter membrane is arranged in the air filter, can filter the air that enters in the dropping funnel.
The exhaust needle external diameter is 0.6mm～2.0mm, and the exhaust needle end that stretches in the dropping funnel is 10mm～25mm with the terminal vertical dimension of dropper, and exhaust needle is provided with the endoporus of a perforation, can supply circulation of air.
The structure that the automatic vent assembly is such can be discharged the air in the dropping funnel during transfusion automatically by gas deflation assembly, can effectively prevent the generation of bubble and prevent that bubble from entering in the transfusion long duct.
The present invention has set up the automatic vent assembly with energy automatic vent function on the basis of traditional disposable infusion set.The present invention 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 manually squeezes dropping funnel aerofluxus bubble.When the present invention uses, confirm earlier whether automatic vent assembly steam vent is opened, flow regulator cuts out, bottle plug puncture unit is inserted in the infusion vessel bottle stopper again, do not need to squeeze dropping funnel with hands, need not hang upside down dropping funnel, medicinal liquid enters in the dropping funnel automatically, and the medicinal liquid liquid level constantly rises, and rises to exhaust needle terminal position height always and just no longer rises, medicinal liquid stops to flow, among this process, the air in the dropping funnel is all discharged by gas deflation assembly, also bubble-free sneaking in the whole communication path, bubble can not resemble and directly enter the general infusion set in the transfusion long duct, thereby prevents that effectively bubble from producing and preventing to enter in the transfusion long duct; Open flow regulator again, medicinal liquid flows out from venoclysis needle, closes flow regulator, and the vein that punctures is routinely opened flow regulator, regulates to drip speed, gets final product normal infusion.The present invention can solve existing transfusion device infusion process because of aerofluxus bubble work loaded down with trivial details, lose time, lack safety guarantee, healthcare givers or patient and family members' mental burden heavily waits problem, remove the patient and in infusion process, enter the worry that human body causes adverse consequencess such as aeroembolism because of gas.
The present invention has following advantage: 1, need not squeeze dropping funnel in the transfusion operation process can introduce medicinal liquid in the dropping funnel, and the step that simplifies the operation alleviates medical personnel's working strength; But 2 automatic vents can prevent that bubble from producing and prevent that bubble from entering in the infusion pipeline that the liquid level in the dropping funnel can be controlled at a level altitude automatically, prevent that liquid level is too high-leveled and difficult to observe medicine liquid droplet speed in the dropping funnel; 3, processing simple in structure, safe and reliable, easy does not change operator's use habit, can the clinical advantage of extensive use.
