Multi-chamber infusion bag

Abstract

The invention discloses a multi-chamber infusion bag. The front part of the infusion bag is provided with a liquid tube, the rear part of the infusion bag is provided with two liquid feeding ports, the inner cavity of the infusion bag, adjacent to the front part, is provided with a microporous baffle, two ends of the microporous baffle are respectively connected with the left and right sides of the inner cavity wall of the infusion bag, the inner cavity of the infusion bag, adjacent to the rear part, is provided with an imporous baffle, one end of the imporous baffle is connected with the rear middle part of the inner cavity wall of the infusion bag, the other end of the imporous baffle is connected with the left side or right side of the inner cavity wall of the infusion bag, the imporous baffle is provided with a valve, and the two liquid feeding ports are respectively arranged at two sides of the center of the rear part of the infusion bag. The inner cavity of the infusion bag is separated into three chambers by the microporous baffle and the imporous baffle, and two chambers adjacent to the rear part are respectively used for holding different medical liquids, so that different medical liquids can be supplied at different times; and the microporous baffle has an effect on sharing the pressure in the liquid tube at the front part.

Description

technical field [0001] The invention relates to an infusion bag, in particular to a multi-cavity infusion bag which divides the inner cavity of the infusion bag into multiple chambers. Background technique [0002] The traditional infusion bag has one inner cavity, so it can only contain one kind of liquid medicine, which has two disadvantages: one is that when another kind of liquid medicine is needed for infusion, the infusion bag needs to be replaced, which is troublesome, especially Two kinds of liquid medicine need continuous or mixed infusion; the second is that the weight of the liquid medicine in the infusion bag is all concentrated on the inner end of the liquid tube at the front of the infusion bag, and the pressure will decrease with the decrease of the liquid medicine, so it will cause the medicine The liquid output speed of the liquid changes greatly, which is not conducive to the stability of the infusion speed. Contents of the invention [0003] The object ...
