Abstract

The utility model relates to a sterilized medical device, in particular to a bubble-free transfusion system, which comprises a bottle stopper puncture tool protective sleeve, a bottle stopper puncture tool, a transfusion short conduit, an exhaust short conduit, an air filter, an upper dropper, a dropping funnel, a flow regulator, a transfusion long conduit, a liquid medicine filter and a disposable venous transfusion needle, wherein the lower end of the dropping funnel is provided with a lower dropper; the lower dropper is arranged on the lower end of the dropper, the top is sealed and the outer side thereof is provided with a liquid inlet through hole; the inner cavity is provided with a liquid inlet channel and a liquid outlet channel, the bottoms of the liquid inlet channel and the liquid outlet channel are blocked and the tops thereof are communicated with each other, and the liquid inlet through hole is communicated with the liquid inlet channel; and the liquid outlet end is sleeved on the transfusion long conduit with the flow regulator. Compared with the prior art, the utility model has the advantages that: 1. the bubble-free transfusion system can prevent bubble from generating and prevent bubble from entering the conduits during the transfusion, and has simple structure, and is safe and reliable, and is easy to manufacture; 2. the bubble-free transfusion system can not change the use habit for the operator and widely applied to clinic.

Description

A kind of bubble-free infusion set

Technical field

This utility model relates to the aseptic medical equipment that is used for the clinical transfusion purposes, especially relates to a kind of bubble-free infusion set.

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 down in the 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 purpose of this utility model is to provide a kind of and can prevents effectively that in infusion process bubble from producing and prevent that bubble from entering in the transfusion catheter, simple in structure, safe and reliable bubble-free infusion set.

The purpose of this utility model is achieved in that this utility model comprises bottle plug puncture unit protective sleeve, bottle plug puncture unit, transfusion tubulature, aerofluxus tubulature, air filter, goes up dropper, dropping funnel, following dropper, flow regulator, transfusion long duct, liquid medicine filter and disposable use venoclysis needle; feature is: dropper down is installed in the dropping funnel lower end, and the liquid outlet of following dropper is enclosed within on the transfusion long duct that has flow regulator.

The top seal of following dropper, the outside is provided with the inlet opening of a perforation, inner chamber is provided with feed pathway and liquid outlet channel, feed pathway and liquid outlet channel bottom intercept but the top is interconnected, inlet opening is communicated with feed pathway, and the shape of inlet opening can be a kind of in ring-type strip or ellipse or the circle.The such structure of following dropper can effectively prevent the generation of bubble and prevent that bubble from entering in the transfusion long duct.

This utility model compared with prior art has following advantage:

This utility model has the generation that can prevent bubble and prevents that bubble from entering the following dropper in the transfusion long duct owing to having set up on the basis of traditional disposable infusion set.This utility model is the same with the transfusion set operating process in use, does not change operator's use habit, does not increase operating procedure, can save the loaded down with trivial details process of artificial aerofluxus bubble; When this utility model uses, after bottle plug puncture unit inserted transfusion bottle stopper, earlier squeeze dropping funnel with hands, medicinal liquid is entered in the dropping funnel, need not hang upside down dropping funnel, when medicinal liquid enters in the dropping funnel, medicinal liquid is with the inlet opening on the dropper sidewall under the very fast covering, the medicinal liquid height constantly rises simultaneously, because of having difference in height between inlet opening and the liquid outlet channel, can't not flowed out by liquid outlet channel before medicinal liquid reach a certain height, medicinal liquid seals inlet opening within certain altitude all the time among this process, therefore the air in the dropping funnel can not be sneaked into by inlet opening, and whole communication path is also bubble-free sneaks into, and bubble can not resemble the general infusion set sample and directly enter in the transfusion long duct, thereby prevent that effectively bubble from producing and preventing to enter in the transfusion long duct, observe and drip speed, regulate flow regulator, get final product normal infusion.This utility model 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, thereby effectively reduce medical personnel's working strength, reduce liquid waste, remove the patient and in infusion process, enter the worry that human body causes adverse consequencess such as aeroembolism because of gas.Therefore the utlity model has and can prevent that in infusion process bubble from producing and prevent that bubble from entering, the advantage of simple in structure, safe and reliable, easy processing, do not change operator's use habit, can extensive use clinical.
