Abstract
A medical cell tissue cryopreservation bag adopts ethylene-ethyl acrylate (EEA) material for blow molding, and comprises plugs, diaphragms, connecting pipes, an upper end wall, a bag body, and a lower end wall. The bag body taking the shape of a hollow square serves as the main body of the preservation bag; the lower end wall and the upper end wall are respectively arranged at the lower end and the upper end of the bag body; the two connecting pipes communicated with the outside are arranged after penetrating through the upper end wall; the plugs are arranged at the outer end ports of the connecting pipes; and diaphragms are arranged in the connecting pipes inside the outer end ports. The cryopreservation bag is suitable for low-temperature or deep-low-temperature long term preservation of unicells, blood cells, embryos, tissues and organs such as sperms, ova, tumor cells, diploid cells, and the like for clinical transplantation and experiments. The cryopreservation bag adopts EEA copolymer and polythene blow molding method in the prior art, and is produced through high frequency thermal synthesis. The utility model has the advantages of simple integral structure, convenient operation and use, non toxicity and side effects, and good stability.
Description
Technical field:
The utility model relates to medical preservation container, relates in particular to medical cellular tissure cryopreservation bag.
Background technology:
Preservation after medically cell, tissue and organ need being exsomatized usually, but they have just lost the control and the adjusting of neural and body fluid after exsomatizing.Along with the prolongation of preservation time, metabolism also will be proceeded, and nutriment such as sugar will be consumed to the greatest extent gradually.In order to suppress the metabolism of cell, prolong the life of cell, prolong the preservation time, it is deposited under subzero 196 ℃ of conditions, just need a kind of transparent being convenient to for this reason and observe, cut the container that can bear the profound hypothermia condition.The low temperature that the polyvinyl chloride bag of prior art bears can not be lower than subzero 80 ℃, although also there is material can be fit to the profound hypothermia environment, costs an arm and a leg, and is not suitable for promoting the use of in hospital.
The utility model content:
The purpose of this utility model is, overcomes the deficiencies in the prior art part, and a kind of medical cellular tissure cryopreservation bag is provided, and should bear the environmental condition of profound hypothermia, and cost price is low again, easy to process, safety.
Medical cellular tissure cryopreservation bag described in the utility model adopts the blow molding of ethylene-propylene acetoacetic ester material, includes pipe close, barrier film, tube connector, upper end wall, bag main body and lower end wall and forms.Short side shape in said bag main body integral body is is a main part of the present utility model, and the lower end position in the bag main body is provided with lower end wall, and the upper end position in the bag main body is provided with upper end wall.See through upper end wall, be provided with two outer logical tube connectors, the external port of said tube connector is provided with pipe close, in the tube connector in external port, is provided with barrier film.
Medical cellular tissure cryopreservation bag described in the utility model, be applicable to that sperm, ovum, tumour cell, diploid cell etc. are unicellular, the long-term preservation of the low temperature of haemocyte, embryo, tissue and organ or profound hypothermia is for the needs of clinical transplantation and experiment.The utility model adopts ethylene-ethyl acrylate copolymer, adopts the blow moulded polyethyene method of prior art, makes through high frequency heat seal.The utility model overall structure is simple, and is easy for operation, has no side effect good stability.
