Break disconnected changeover portion；Locating notch is provided with the excircle of the enclosing cover upper surface；On the upper surface excircle of the inner cap
It is provided with the coordinate breach corresponding with the locating notch.
Further, annular groove is provided with the upper and lower end face of the plug, the outer interior surface is filled described
The annular flange being engaged with the annular groove is provided with the lower surface for noting pipe, the upper surface of the inner cap is provided with and institute
State the annular flange that annular groove is engaged.
Further, the interface includes welding pedestal, is arranged in the welding pedestal and stretches out the defeated of its one end
Liquid mixes medicine passage, projection of the welding pedestal in its cross section stretch out in ship shape or rhombus, its two ends to be formed thickness by
The thin thin slice of gradual change, the lower surface of the welding pedestal is provided with boss.
Further, the mixed medicine passage of the transfusion is cylindrical tube structure.
Further, two locating notches are symmetrically arranged with the excircle of the enclosing cover upper surface.
Further, it is evenly arranged with locating notch described at least two on the excircle of the enclosing cover upper surface.
Further, the wide 1mm of the locating notch, deep 2mm.
Further, the endoporus of the mixed medicine passage of the transfusion is ellipse, and ellipse nozzle diameter is without departing from the weldering
Connect the thickness of pedestal ship shape or diamond-shaped portion.
The beneficial effects of the utility model are：First, it is being provided with locating notch on the excircle of the enclosing cover upper surface；Institute
The coordinate breach corresponding with the locating notch is provided with the upper surface excircle for stating inner cap and plug；Avoid turning to match somebody with somebody
Occurs misalignment in welding process；2nd, it is described welding pedestal lower surface be provided with boss, can at the top of welding with it is defeated
Liquid mixes and forms certain cavity at medicine passage, in order to reduce transfusion residual quantity while avoiding weld mold and film in welding process
Material crosses fusion welding, increases edge weld strength；3rd, the endoporus of the mixed medicine passage of the transfusion is ellipse, it is to avoid at a high speed
The trapped gas phenomenon occurred during perfusion.
