The specific embodiment
Below, with reference to the accompanying drawings, this utility model is more fully illustrated, shown in the drawings of exemplary embodiment of the present utility model.Yet this utility model can be presented as multiple multi-form, and should not be construed as the exemplary embodiment that is confined to narrate here.But, these embodiment are provided, thereby make this utility model comprehensively with complete, and scope of the present utility model is fully conveyed to those of ordinary skill in the art.
In order to be easy to explanation, here can use such as " on ", the space relative terms such as D score " left side " " right side ", be used for element shown in the key diagram or feature with respect to the relation of another element or feature.It should be understood that except the orientation shown in the figure spatial terminology is intended to comprise the different azimuth of device in using or operating.For example, if the device among the figure is squeezed, be stated as the element that is positioned at other elements or feature D score will be positioned at other elements or feature " on ".Therefore, the exemplary term D score can comprise upper and lower orientation both.Device can otherwise be located (90-degree rotation or be positioned at other orientation), and the relative explanation in used space here can correspondingly be explained.
As shown in Figures 1 to 4, a kind of transfusion bag interface of this utility model comprises integrated lid welding ring 1 and tube for transfusion 2, the link 5 that tube for transfusion 2 comprises the port of export 4 and is used for being combined with transfusion bag, and lid welding ring 1 is arranged on the top of the port of export 4.Lid welding ring 1 and tube for transfusion 2 inside are provided with through hole 3 along the radially perforation of body.
The cross-sectional profile of tube for transfusion 2 is flat prismatic structure 7.The cross-sectional profile of lid welding ring 1 is circular configuration, and its external diameter is greater than the major diameter of described flat prismatic structure 7, and the internal ring of lid welding ring 1 is transfusion through hole similar round.The cross-sectional profile of through hole 3 is the similar round structure, and such circular configuration is connected and composed by four arcs.Wherein, the inside and outside wall of tube for transfusion 2 all progressively dwindles with tapering from top to bottom, that is: the hole shape of the profile of tube for transfusion 2 and through hole 3 is from top to bottom and progressively dwindles with tapering, and the taper value A of this tapering is that taper value is preferably 0.3 ° between 0.2 °-0.6 °.
