TECHNICAL FIELD
[0001] The utility model relates to the technical field of medical apparatus and instruments, more specifically, to a multi-chamber infusion soft bag. BACKGROUND
[0002] In intravenous infusion therapy, multi-chamber infusion soft bags have become one of the important medical devices. By keeping drugs separate before infusion, such products effectively reduce the risk of chemical reactions between drugs, improving the safety and efficacy of drug use. In recent years, with the increasing diversification of clinical needs, especially the demand for multiple drug combinations under complex conditions, four-chamber or even more-chamber infusion soft bags have gradually attracted attention. This development trend not only promotes the progress of medical technology, but also brings patients a more efficient and convenient treatment experience.
[0003] Currently, the multi-chamber infusion soft bags on the market mainly include powder-liquid dual-chamber bags, liquid-liquid dual-chamber bags, and liquid-liquid triple-chamber bags. The common design scheme of these products is to use one or more vertically arranged weak welds to divide the entire bag into several independent small chambers, each chamber is equipped with an independent filling port for adding different types of liquid medicine. This design meets the needs of simultaneous infusion of multiple drugs to some extent, but still has some shortcomings in actual application. First, all chambers share the same width size, which leads to the fact that when the liquid volume in a certain chamber is too small, the liquid medicine cannot flush the chamber, easily causing the inner cavity to stick together and become a waste product.

[0034] The core of the present application is to provide a ready-to-use multi-chamber infusion soft bag.
[0035] Please refer to Figures 1 to 4 .
[0036] The ready-to-use multi-chamber infusion soft bag provided by the present application comprises a bag body 1, an easy-to-open weld 2 is arranged in the bag body 1, the easy-to-open weld 2 divides the bag body 1 into at least four chambers of different sizes, and at least one of the welds in the easy-to-open weld 2 has a bending part.
[0037] Specifically, the easy-to-open weld 2 is arranged in the bag body 1, and the bag body 1 is divided into at least four chambers of different sizes by the easy-to-open weld 2, and it should be noted that the welding strength of the easy-to-open weld 2 should be 8N / 15mm~15N / 15mm, and the easy-to-open weld 2 can be opened by applying some external force. The weld with the bending part can cooperate with the edge of the bag body 1 to divide a relatively small chamber, and the small chamber can be used to store a liquid medicine with a small amount of liquid medicine, so that in the process of mixing the liquid medicine, the chamber capacity of the liquid medicine with a small amount of liquid medicine is small, and a certain external force can easily break the easy-to-open weld 2 with the bending part corresponding to the chamber.
[0038] The above-mentioned multi-chamber infusion soft bag is divided into at least four chambers of different sizes by the easy-to-open weld 2, wherein the weld with the bending part divides two adjacent chambers into two chambers with different sizes, and the difference between the two chambers can be adjusted according to specific requirements, so that in the process of mixing the liquid medicine, the liquid medicine with a small amount of liquid medicine can be injected into the small chamber divided by the weld with the bending part, and in the mixing process, the liquid medicine with a small amount of liquid medicine can also break the weld of the small chamber, so that the liquid medicine in different chambers can be better mixed under different liquid capacities.
[0039] The multi-chamber infusion soft bag provided by the utility model will be described in more detail in combination with the drawings and specific embodiments.
[0040] In a specific embodiment, referring to Figure 1 , the easy-to-open weld 2 includes a first weld 21 and a second weld 22, the first weld 21 is vertically arranged in the middle of the chamber, and the second weld 22 is arranged in two, and the two second welds 22 are both L-shaped welds, and the first weld 21 and the second weld 22 divide the chamber into a first chamber 31, a second chamber 32, a third chamber 33 and a fourth chamber 34.
