Embodiment Construction

[0077] [77] FIG. 1 shows a container 1 enclosing a disposable pouch 2 of substantially parallelepiped shape. The lower surface of the pouch 2 has an orifice for draining the liquid to the outside of the pouch and the upper surface has an orifice for returning the liquid through which the liquid can flow back into the interior of the pouch 2 . The two orifices of the bag 2 are connected in a fixed manner by a mixing duct 3 .

[0078] [78] Functionally, the fixed mixing conduit 3 is inserted into a pump 4 located at the top of the pouch, which rotates to circulate the liquid, for example from the bottom of the pouch in the direction indicated by the arrows. flow to the top.

[0079] [79] Due to the provision of two doors 5, 6, the sides of the container 1 can be opened, so that the container 1 can be opened laterally. Thus, it is easy to fill the bag 2 with the fixed conduit 3 into the container 1 and to insert the mixing conduit 3 into the pump 4 in operation.

Abstract

The inventive single-use closed system for mixing, storing and homogenising liquids comprises an assembly consisting of a rigid container (1) provided with a non-invasive pump (4) and a single-use generally parallelepipedic cavity (2) whose lower and top faces are fixedly connected to each other by means of a mixing pipe (3) which is inserted into the pump (4) and, when operating, enables the liquid to recirculate in said cavity (2), for example from the bottom thereof upwards to the top thereof, said pump (4) being openable in such a way that it is possible to insert therein and remove the mixing pipe (3) therefrom.

Description

technical field [0001] [01] The present invention relates to a disposable closed system for mixing, storing, and homogenizing liquids under clean or aseptic conditions, preferably, the system is used in the biopharmaceutical industry, the pharmaceutical industry, and the medical field . Background technique [0002] [02] Mixing large volumes of fluids under clean or sterile conditions is problematic not only in the medical, biopharmaceutical, pharmaceutical, or paramedical fields, but also in other fields such as the food industry, among others. [0003] [03] Mixing liquids under clean or aseptic conditions is a common practice that must generally meet the following criteria: [0004] [04] - keeping the original bio-charge in the constituents of the mixture as well as in the mixture itself at the lowest possible level; [0005] [05] - limit the mixture components and the content of endotoxin in the mixture as far as possible (the above two guidelines are often combined); ...
