The utility model aims at overcoming the not enough among the above-mentioned background art, provide a double-tube formula infusion bag ship type interface of improvement dosing pipe, this interface should be able to firmly fix the plug in dosing pipe.
The technical scheme of the utility model is that:
the double-tube transfusion bag boat-shaped interface of the improved dosing tube comprises a base, a transfusion tube and a dosing tube, wherein the transfusion tube and the dosing tube are vertically fixed on the bottom surface of the base; the method is characterized in that: the outer circumference of the bottom end of the dosing tube is provided with a boss, the bottom surface of the boss is also provided with an axially extending extension tube, and the outer diameter of the extension tube is smaller than that of the boss.
The outer diameter of the boss is 11-13mm and the height of the boss is 6-7 mm; the outer diameter of the lengthening pipe is 9-10mm and the height of the lengthening pipe is 1.5-2.0 mm.
The bottom surface of the boss is a conical surface.
The projection of the base on the horizontal plane is ship-shaped or diamond-shaped.
Base width direction's both sides are equipped with 3 strengthening ribs of horizontal arrangement respectively: and the two ends of the base are provided with vertically arranged fins.
And the base is respectively provided with an infusion tube hole communicated with the infusion tube and a medicine adding tube hole communicated with the medicine adding tube.
The horizontal distance between the infusion tube and the medicine feeding tube is 15-25 mm.
The utility model has the advantages that:
the utility model discloses the bottom of well dosing pipe can cover around the plug after the thermal deformation to firmly fix the plug, simple structure and production convenience have effectively ensured product quality.

Detailed Description
The present invention will be further described with reference to the drawings attached to the specification, but the present invention is not limited to the following embodiments.
As shown in fig. 1, the improved double-tube transfusion bag boat-shaped interface of the medicine feeding tube comprises a base 1, a transfusion tube 2 and a medicine feeding tube 3. The infusion tube and the dosing tube are vertically fixed on the bottom surface of the base, the horizontal distance between the infusion tube and the dosing tube is 15-25mm, infusion tube holes 1.3 communicated with the infusion tube and dosing tube holes 1.4 communicated with the dosing tube are respectively arranged on the base, the infusion tube holes and the dosing tube holes are communicated with the upper end surface and the lower end surface of the base, and 3 horizontally extending reinforcing ribs 4 are symmetrically arranged on two sides of the base in the width direction (the vertical axis of the figure 2).
The chemical feeding pipe is internally provided with a blocking plate 3.1, the outer circumferential surface of the bottom end of the chemical feeding pipe is provided with a boss 3.2, the bottom surface of the boss is a conical surface, and the bottom surface of the boss is also provided with a vertically and downwardly extending extension pipe 3.3. The boss has an outer diameter of 11-13mm (preferably 12mm) and a height of 6-7mm (preferably 6.5 mm). The outer diameter of the extension pipe is smaller than that of the boss, the outer diameter of the extension pipe is 9-10mm (preferably 10mm) and the height of the extension pipe is 1.5-2.0mm (preferably 1.8 mm).
The projection of the base on the horizontal plane is boat-shaped as shown in fig. 2, or diamond-shaped as shown in fig. 3. The two ends of the base are provided with vertically arranged fins 6.
When the rubber plug is installed, the direction of the connector is adjusted firstly (the dosing pipe of the connector faces upwards), then the rubber plug 6 is placed in the dosing pipe, then the lengthening section is heated, the lengthening section flows around after being softened and covers the boss and the edge position of the rubber plug (as shown in 3.4 in figure 6), and the rubber plug can be firmly fixed in the dosing pipe after being solidified.
