A kind of automatic venting device of transfusion device
Technical field
This utility model product belongs to medical instruments field, specially refers to a kind of automatic vent type transfusion device in patient's infusion medicinal liquid process.
Background technology
Present clinical use general infusion set need to be inverted dropping funnel carrying out the medicinal liquid infusion, and the extruding dropping funnel, after making a certain amount of liquid be full of dropping funnel, along putting dropping funnel, could be with most of removal of bubbles, if in misoperation, dropping funnel, liquid and admixture of gas enter flexible pipe, form bubble.Enter in patient body as bubble, easily cause the harm of aeroembolism.So, before medical personnel infuse, must be with the emptying as far as possible of the bubble in hose of infusion apparatus, the process of this artificial aerofluxus bubble is not only loaded down with trivial details but also consuming time, has increased medical personnel's work load.
Therefore, in clinical transfusion, use a kind of automatic vent type transfusion device just particularly important.
Summary of the invention
This utility model is to adopt following technical proposals to realize: a kind of automatic venting device of transfusion device, formed by automatic vent pipeline and infusion unit titrimeter, and it is characterized in that, transfusion device automatic vent pipeline (2) is arranged in infusion unit titrimeter (1).
The automatic vent pipeline is inserted in infusion unit titrimeter, and automatic vent pipeline top is provided with venting plug, air-filtering membrane and 1 steam vent, and automatic vent pipeline and dropping funnel upper end liquid outlet be not on same.This utility model is simple in structure, and manufacturing process is simple, and production cost is low.Particularly adopt this automatic venting device of transfusion device, can automatic vent in infusion process, use simply, make transfusion safer.
