Problems solved by technology

[0006] The widely used clinical material for storing cells in liquid nitrogen is the cell storage bag of Miltenyi Biotec, which has been approved by the U.S. FDA and approved by the Chinese Drug Administration; 1. Each stage of resuscitative centrifugation needs to use different containers, resulting in increased exposure to air and increased chances of cell product contamination
In addition, when used by clinicians, cells need to be aspirated into different containers. The aspiration process may be polluted and some cells may be destroyed.
[0007] The inventors of the present invention aimed at the technical problems existing in the prior art, such as low recovery rate, non-uniform operation process and the above-mentioned frozen cells being easily polluted and damaged, through a careful study of the whole process of cell recovery after freezing , design a new type of cell freezing and recovery container

Abstract

The invention relates to a multifunctional container for freezing cells and resurrecting frozen cells. The multifunctional container comprises a freezing bag, wherein the freezing bag is provided with an elliptical bottom and a rectangular upper part in an idle state. The multifunctional container is characterized in that a thickening layer is arranged at the elliptical bottom of the freezing bag; and a lavage and output channel, a cell input pipeline and a cleaning liquid entrance pipeline are also connected to the bag mouth of the freezing bag. The multifunctional container for freezing the cells and resurrecting the frozen cells has the advantages that the effect of multifunction by one bag is achieved; the preparation process of the cells and clinical use are facilitated; more importantly, the possibility that the cells are in contact with air and are polluted is greatly reduced; and the quality control over the cells and the purity of products are facilitated.

Description

technical field [0001] The invention relates to a medical device, in particular, the invention relates to a container used for freezing, resuscitating and infusion of cells. Background technique [0002] With the development of biological technology, cell therapy is developing rapidly and being accepted by people all over the world. Fundamental to cell therapy is the acquisition and storage of living cells. In addition, the in vitro culture of cells has also been widely used in various biological research fields. In in vitro cell culture work, in order to preserve cells and make them biologically active for a long time, cell cryopreservation and recovery have become crucial links. The preparation and storage of cells, especially the low-temperature storage of stem cells, the recovery conditions and the prevention of contamination during the operation process are important issues in the clinical application of cell therapy. Many countries and regions have established vario...
