Problems solved by technology
The connecting pipe and the cover are welded together mainly by heating the contact surfaces. The disadvantage of this connection method is that due to the non-contact heating and melting sealing technology, there is liquid medicine on any contact surface between the connecting pipe and the cover. As a result, it cannot be welded firmly and there is a hidden danger of liquid leakage, and the heating plate is prone to slag and particles when used for a long time, which seriously endangers the quality of the liquid medicine and the safety of medication.

The invention discloses a connection device for soft bag infusion. The connection device comprises a connection pipe, an opening cover and a sealing plug, wherein the opening cover is connected with a pipe opening of the connection pipe; the sealing plug is arranged between the pipe opening of the connection pipe and the inner bottom face of the opening cover; the pipe opening of the connection pipe comprises an outer pipe opening and an inner pipe opening; the opening cover is placed in a groove formed by an inner side wall of the outer pipe opening and an outer side wall of the inner pipe opening; and the lower end of the sealing plug is placed in the inner pipe opening. According to the connection device for the soft bag infusion, the firm and reliable connection between the connection pipe and the opening cover is realized; the connection device for the soft bag infusion is good in sealing performance, simple in structure, convenient to manufacture, safe to use and low in cost.
Description
technical field [0001] The present application relates to the technical field of medical packaging, in particular to a connection device for soft bag infusion. Background technique [0002] At present, the connecting tubes and mouth caps involved in the production of non-PVC soft bag infusion are independent of each other, and the mouth caps are basically composed of a lid body (the lid body is basically composed of an inner lid body and an outer lid body), a sealed silicone rubber plug combined. The disadvantage is that due to its complex structure, the mouth cover has correspondingly more procedures in terms of technology and production arrangement, so its production input and production cost are relatively high, there are many intermediate links, the risk of pollution increases, the operation is cumbersome and inconvenient, and the production efficiency is low. Low. In addition, four or five kinds of materials are used for the connection pipe and the mouth cover in the ...
