[0029] The following further details the present application with reference to the drawings.

[0030] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as up, down, front, back, left, right, etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0031] The embodiment of the present application discloses an infusion interface for an infusion bag, referring to Figure 1 and Figure 4, including an upper cover 1, a lower cover 2 and a rubber plug 3. The upper cover 1 includes a fixing part 13, a connecting part 12 and a folding handle 11. The fixing part 13 is substantially set in the shape of a round cover. A through hole is vertically opened inside the fixing part 13 to form a fixing part opening 133. A circular protrusion is provided along the periphery of the fixing part opening 133 at the bottom of the fixing part 13 to form a fixing flange 131. A circular protrusion is also provided at the bottom of the fixing part 13 to form a welding flange 132, and the welding flange 132 is arranged on the periphery of the fixing flange 131.

[0032] The lower end of the folding handle 11 is set to be circular, and along the vertical direction of the folding handle 11 upwards, an arc-shaped cut is made on the side end of the folding handle 11 to form a hand-held part 115. The hand-held part 115 makes an arc-shaped transition towards the direction away from the lower cover 2, so that the upper end of the hand-held part 115 forms a handle shape, which is convenient for the operator to hold and grab. Arrow-shaped grooves are opened on both sides of the hand-held part 115 to form direction marks 112, and the direction marks 112 are used to remind the operator.

[0033] Refer to Figure 3 , the connecting part 12 includes an upper connecting piece 121, a breaking part 122 and a lower connecting piece 123. The lower connecting piece 123 is arranged at the top of the fixing part 13 along the vertical direction of the fixing part 13, and the upper connecting piece 121 is fixedly arranged at the bottom of the folding handle 11. One end of the upper connecting piece 121 away from the folding handle 11 is narrowed, that is, the cross-sectional width of the upper connecting piece 121 near the folding handle 11 is set to be smaller than the cross-sectional width near the lower connecting piece 123, and the cross-sectional width of the lower connecting piece 123 near the fixing part 13 is set to be larger than the cross-sectional width near the upper connecting piece 121. A breaking part 122 is integrally arranged between the upper connecting piece 121 and the lower connecting piece 123, and the breaking part 122 has a thinner cross-sectional thickness. By pulling the folding handle 11 upwards, the breaking part 122 can be torn, so as to perform the operation of opening the cover.

[0034] Refer to Figure 2 , a circular groove is opened at the bottom of the folding handle 11 to form a folding handle cavity 113. A plurality of reinforcing blocks 114 are integrally arranged on the inner wall of the folding handle cavity 113, and the plurality of reinforcing blocks 114 are arranged at intervals along the inner wall of the folding handle cavity 113. The reinforcing blocks 114 play a supporting role for the folding handle cavity 113, improve the extrusion resistance performance of the folding handle cavity 113, and prevent the folding handle cavity 113 from being deformed and damaged when the folding handle 11 is pulled. The upper connecting piece 121, the breaking part 122 and the lower connecting piece 123 are all set in the shape of a hollow circular ring, and the folding handle cavity 113 is communicated with the fixing part opening 133 through the connecting part 12.

[0035] Refer to Figure 1 , a notch is opened at the top of the folding handle 11 to form a notch 111.

[0036] Refer to Figure 1 andFigure 4 , the lower cover 2 is substantially set in a cylindrical shape, and the lower cover 2 is fixedly welded to the upper cover 1. Specifically, the welding flange 132 is welded to the top of the lower cover 2 to fix the upper cover 1 and the lower cover 2. An extension part 24 is integrally provided at the bottom of the lower cover 2, and a cavity is formed inside the extension part 24 to form an extension cavity 26, and the inside of the lower cover 2 is hollow. A flange is provided on the inner wall of one end of the extension cavity 26 close to the lower cover 2 to form a diaphragm outer edge 23, and a diaphragm 22 is integrally provided on one side of the diaphragm outer edge 23 away from the inner wall of the extension cavity 26. The diaphragm 22 is used to partition the extension cavity 26 and the inside of the lower cover 2. In order to facilitate puncturing the diaphragm 22, the thickness of the diaphragm 22 is set to be less than the thickness of the diaphragm outer edge 23. The diaphragm outer edge 23 plays a role in fixing and supporting the diaphragm 22. When the needle punctures the diaphragm 22, it can prevent the entire diaphragm 22 from falling off and into the infusion bottle. The fixing part 13 and the diaphragm 22 and the diaphragm outer edge 23 jointly form a cavity to form a rubber stopper cavity 21, and the rubber stopper 3 is arranged in the rubber stopper cavity 21. An annular groove is provided at the top of the rubber stopper 3, and the fixing flange 131 is inserted into the annular groove to clamp and fix the rubber stopper 3. The top of the rubber stopper 3 is aligned with the opening 133 of the fixing part in the vertical direction, which is convenient for the needle to puncture the rubber stopper 3.

[0037] The extension part 24 is set in a flat tubular structure, and the cross-sectional shape of the extension cavity 26 along its own length direction is substantially set in a rhombus shape. A plane is provided on the side of the extension part 24 close to the lower cover 2. The extension part 24 is provided with a certain length so that the extension part 24 can extend into the infusion bottle, and the extension part 24 is welded and sealed at the bottle mouth of the infusion bottle.
