The invention discloses a cover for an infusion bag. The cover comprise a cover body, wherein a dosing cavity connected with a dosing connecting pipe and an infusion cavity connected with an infusion connecting pipe are formed in the cover body; a first sealing layer is arranged on the inner side of the dosing cavity, a first easy-to-tear sealing film is arranged on the outer side of the dosing cavity, and a sealing plug is arranged between the first sealing layer and the first easy-to-tear sealing film; a second sealing layer is arranged on the inner side of the infusion cavity, a second easy-to-tear sealing film is arranged on the outer side of the infusion cavity, and a sealing device matched with the infusion connecting pipe is arranged on the infusion cavity between the second sealing layer and the second easy-to-tear sealing film. Compared with the prior art, the cover has the advantage that the sealing device is arranged in the infusion cavity, so that the better sealing performance can be realized.
Description
technical field [0001] The invention relates to the technical field of medical packaging materials, and more specifically relates to a combined cover for an infusion bag and an infusion bag. Background technique [0002] With the development of packaging science and technology and the continuous development and utilization of new packaging materials, in modern medicine, soft bag infusion bags have replaced the earlier glass bottles. For soft bag infusion bags, a suitable cover is particularly important. In the disclosed technology, the lid of the infusion bag is generally a combined pull-tab lid or a combined easy-fold lid, and its basic structure generally includes a lid body and a sealing silicone rubber plug for sealing. When the infusion bag needs to be used, the sealing film on the cover body is removed first, and then the sealing rubber plug is exposed, and then a needle tube is used to penetrate the sealing rubber plug for feeding medicine or infusion. [0003] In t...
