Abstract

The invention relates to a medical profound hypothermia storage bag having a function of protecting a liquid inlet pipe. The storage bag comprises a bag body and a pipeline. A liquid outlet pipes and a liquid inlet pipe which are communicated with the inner and outer sides of the bag body are arranged at the port of the storage bag. The liquid inlet pipe is communicated with an external pipeline. The bag body is formed by banding an upper film and a lower film. Upper and lower two pairs of butterfly wings are arranged on the liquid outlet pipe. The upper and lower films extend out 3 to 5 mm of the liquid inlet pipe and the liquid outlet pipe, at the position close to the binding wire of the bag port. The lower butterfly wings of two liquid outlet pipes are close to one side of the liquid inlet pipe and are welded with the upper and lower films in order to cover the liquid inlet pipe. The medical profound hypothermia storage bag of the invention has no phenomenon of breaking the liquid inlet pipe in the process of freezing and unfreezing and no liquid inlet pipe is damaged. The invention has the function of excellently protecting the liquid inlet pipe.

Description

technical field [0001] The invention relates to medical equipment, in particular to a cryogenic (-196° C.) preservation bag with a novel structure for preservation of living cells, and a method and mold for making the preservation bag. Background technique [0002] Deep low temperature (-196°C) preservation can greatly reduce the metabolism of cells and delay the loss of their functions. In view of the clinical use of special methods to cool biological tissues or organs to deep low temperature and store them for a long time, when needed, they can be stored again. It is rewarmed in a special way in order to obtain living organisms. Therefore, a suitable cryogenic storage container is the key. The container must have a certain degree of transparency for easy observation, non-toxic to the human body, good physical and chemical properties, and must have excellent low temperature resistance. Preserved under the best conditions to achieve no damage and no leakage. Existing soft ...
