Embodiment Construction

[0011] As shown in the figure, the hard mouth tube of the infusion bag of the present invention includes a body 1, and a vertical through hole 2 is provided on the body 1. One end of the body 1 is a connecting portion 4, and the other end is an outlet portion 3. There is a transition part 5 in the middle of the body 1 for connecting the outlet part 3 and the connection part 4. The through hole 2 is circular in the outlet part 3 and flat rhombus in the connection part 4. The transition part 5 The wall thickness of the connecting portion 4 transitions from thick to thin from the outlet portion 3 to the connecting portion 4, and the outer wall of the connecting portion 4 is oblate rhombus. The flat diamond-shaped design makes the thickness of the side wall of the connection part of the hard mouth tube of the infusion bag uniform and thinner, so that the heat sealing will not be uneven, the heat sealing quality is good, and the material is saved. At the same time, the design of...

Abstract

The invention discloses a hard mouth tube of an infusion bag, which comprises a body, and a through hole in the vertical direction is arranged on the body, one end of the body is a connection part, and the other end is an outlet part, and there is a section in the middle of the body for The transition part connecting the outlet part and the connection part, the said through hole is circular in the outlet part and oblate rhombus in the connection part, and the wall thickness of the transition part transitions from thick to thin from the outlet part to the connection part. The flat diamond-shaped design makes the thickness of the side wall of the connection part of the hard mouth tube of the infusion bag uniform, so that heat sealing will not be uneven, the heat sealing quality is good, and materials are saved. At the same time, the design of the transition part further saves materials.

Description

technical field [0001] The invention relates to the technical field of medical packaging, in particular to a hard mouth tube of an infusion bag. Background technique [0002] In the clinical treatment of diseases, patients are often given infusions or drugs are directly injected into the body through intravenous infusion, so medical solution packaging containers are needed. The existing liquid medicine is packaged with a bottle or a bag, and the infusion bag has a hard mouth tube at the output end. When sealing, insert the connecting part of the hard mouth tube into the opening of the soft infusion bag, and heat and weld the bag with a special device. The interface is welded and formed at one time. In order to make the infusion bag mouth and the hard mouth pipe weld firmly, so generally the connecting portion of the hard mouth pipe is shaped on two wings, and convex ribs are formed in the two wings. In the prior art, the wall thickness of the connection part is too thic...
