Single aperture tube liquid-liquid multi-chamber transfusion soft bag and its production method

Abstract

The invention relates to a multiple-cavity soft bag for transfusion of single group aperture tube liquid and the production method and belongs to the medical transfusion vessel. The product is used for storing transfusion preparation. A sealed bag body is formed by welding the edges of two pieces of bag films. The bag body is provided with a plurality of dissolving liquid chambers. The invention is characterized in that two adjacent chambers are insulated by virtual weld seam, and one group of aperture tubes are fixedly connected with one of the dissolving liquid chambers; at least two positioning holes are arranged at one end of the sealed bag body which is opposite to the aperture tubes; liquid filling openings are correspondingly arranged at the edge of the bag body which is opposite to each dissolving liquid chamber. Only one group of aperture tubes are used in the soft bag, which reduces the quantity of the aperture tubes and the product cost; the virtual weld seam is used for insulating, which is simple, convenient, safe and reliable and no pollution; the positioning holes are also directly used as hanging holes, which reduces the working procedure of processing the hanging holes and further saves the film material and reduces the product cost and is also convenient for using, so the invention meets the requirement of the convenient use from a plurality of aspects. The production method of the invention is simple, convenient and direct and can be easily realized.

Description

Technical field [0001] The invention relates to a single-group orifice liquid-liquid multi-cavity infusion soft bag and a production method thereof, belonging to medical infusion containers, and the product is used for storing infusion preparations. Background technique [0002] For many years, multi-chamber medical bags have been used to prepare mixed solutions. The existing multi-chamber bags use different devices as isolation and insulation between chambers. The isolation parts are rigid and fragile materials, which have the advantage of high versatility. The disadvantage is that the cross section of the mixing port is limited, and undesired particles will be formed after the isolation structure is broken, and there will be a certain degree of pollution. There are also some multi-chamber containers that use detachable heat-welded seals to isolate fluids, and flexible bags made of polymer films, but the number of mouth tubes is large, and the structure and production proce...
