Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Example 1

As shown in fig. 2-3, the embodiment discloses an infusion bag with indentations, which comprises a front membrane material 11 and a rear membrane material 2, wherein the periphery of the front membrane material 1 and the periphery of the rear membrane material 2 are connected in a pressing manner, the top end of the front membrane material is provided with an opening for connecting an infusion pump pipeline, and the front membrane material 11 and the rear membrane material 2 are provided with a plurality of indentation lines 3 extending along the length direction of the front membrane material and the rear membrane material.

The indentation lines 3 on the front membrane material 1 and the rear membrane material 2 are arranged in a crossing way, and a plurality of mutually communicated drainage groove structures are formed between the front membrane material 1 and the rear membrane material 2.

When the infusion bag is used, the opening at the top of the infusion bag is connected with the pipeline of the infusion pump, the infusion pump extracts liquid from the infusion bag in the infusion process, so that the gap between the front membrane material 1 and the rear membrane material 2 is reduced, and as the front membrane material 1 and the rear membrane material 2 are provided with indentations, the liquid can move upwards along the drainage groove structure, thereby avoiding liquid retention at the bottom of the infusion bag and improving the utilization rate of the liquid.
