Abstract
The utility model relates to a container suitable for a liquid nitrogen pot to store and freeze cells or tissues, which belongs to a freezing storage device for cells or tissues and relates to a container for freezing and storing cells and tissues of the liquid nitrogen pot. The purpose of the utility model is to design a freezing and storing container which can systematically store and freeze pipes and enhance the livability of frozen and stored cells. The container comprises a barrel body 1 which is divided into a plurality of layers by partition boards 2 distributed with holes 7, wherein an inserted door 3 is arranged on the barrel wall of the barrel body 1; cryogen circulation holes 5 are distributed on the barrel wall of the barrel body 1; the transverse section of the barrel body 1 is a polygonal surface or a curved surface. The utility model has the advantages of convenient operation of storing and freezing pipes, simple operation, time saving, high cell livability, large storage capacity and liquid nitrogen saving.
Description
Affiliated technical field
The utility model belongs to the cell or tissue refrigerating plant, particularly the cell or tissue refrigerated container of liquid nitrogen container.
Background technology
The chemical property of nitrogen is torpescence very, is commonly used to as protection gas.In medical science and biologically, animal and plant cells storage subzero 196 ℃ of liquid nitrogen commonly used are as refrigerant.The refrigerated container of existing liquid nitrogen container is carried tube like one, is used for placing the frozen pipe that cell or tissue is housed.Can not stop frozen pipe more again and float on the refrigerant surface owing to carry tube, can not effectively utilize in practice, be placed directly in liquid nitrogen container after the heavy cloth bag that weighs down thing is housed and often frozen pipe is put into.But disorderly and unsystematic by the freeze pipe that this mode is put, the snarly sign of identification access is time-consuming bothersome; Accumulation stacks and also causes top frozen pipe to leave the liquid nitrogen overlong time making Apoptosis.Chinese patent notification number 88109174.x, but the living cells container is cultivated in the sterilizing gas infiltration, sealable parts or base and lid are provided, the purpose of its invention is to prevent that hydrogen peroxide steam from entering salable parts inner tissue or cell culture container, and still can permeate other gas.But this invention does not relate to the container of the inner freeze-stored cell of liquid nitrogen container.
Technical scheme
The purpose of this utility model is the deficiency that exists at existing container, design a kind of can be systematically, access stores freeze pipe easily, and can improve the frozen container of liquid nitrogen container of the survival rate of freeze-stored cell or tissue.
For achieving the above object, the utility model comprises cylindrical shell 1 and the handle 4 of putting the frozen pipe of cell or tissue, and the dividing plate 2 in described cylindrical shell 1 usefulness cloth hole 7 is divided into several layers, is provided with to insert door 3 on the barrel of cylindrical shell 1.
Fully freezing in order to allow the frozen pipe that is shelved on 1 li of cylindrical shell be subjected to, on the barrel of cylindrical shell 1, be furnished with the hole 5 of feed flow nitrogen circulation.
The utility model cylindrical shell 1 lateral cross section is polygon or curved surface.
The utility model design is also uncomplicated, yet, because layering can no longer need burdensome cloth bag, freeze pipe directly can be put into without any confusion layer storage, access is convenient, saves time; The restriction of dividing plate can make freeze pipe remain on definite position, prevents that frozen pipe from floating on the liquid nitrogen surface and the survival rate of reduction freeze-stored cell or tissue; And can select the geometrical cross-sectional shape of cylindrical shell as required, rationally increase memory capacity.In addition, dividing plate keeps freeze pipe in the position of determining, even liquid level descends, also can adjust the freeze pipe level, and liquid nitrogen is fully used.
Description of drawings
Fig. 1 is that the utility model cylindrical shell xsect is the synoptic diagram of circular face.
Fig. 2 is that the utility model cylindrical shell xsect is polygonal synoptic diagram.
Embodiment
Embodiment 1: do the circular cylinder body 1 that cylinder does not mate with stainless steel, the opening position of reserving at cylindrical shell 1 is provided with for movable door 3 chutes that move of inserting, and there is the hook 6 towards cylindrical shell 1 top of slotting door 3.Fix with cylindrical shell 1 inwall and cylindrical shell 1 is divided into 6 layers with the dividing plate 2 in cloth hole 7; Cylindrical shell 1 is handle 4 fixedly, and handle 4 length exceed cylindrical shell 1 suitable distance; And on the barrel of cylindrical shell 1 even cloth hole 5.
Embodiment 2: doing the xsect that does not mate with stainless steel is hexagonal cylindrical shell 1, insert door 3 chutes that move on one side the gap of reserving in the cross section is provided with for movable, and configuration is inserted door 3 and linked up with 6; Cylindrical shell 1 is divided into 6 layers, and every layer of dividing plate 2 with cloth hole 7 fixed with cylindrical shell 1 inwall; Cylindrical shell 1 is handle 4 fixedly, and handle 4 length exceed cylindrical shell 1 suitable distance; And on the barrel of cylindrical shell 1 cloth hole 5.
Claims (3)
1, a kind of container that is suitable for liquid nitrogen container storage freeze-stored cell or tissue, comprise cylindrical shell (1) and the handle (4) of putting the frozen pipe of cell or tissue, it is characterized in that cylindrical shell (1) is divided into several layers with the dividing plate (2) in cloth hole, on the barrel of cylindrical shell (1), be provided with and insert door (3).
2, a kind of container that is suitable for liquid nitrogen container storage freeze-stored cell or tissue according to claim 1 is characterized in that on the barrel of cylindrical shell (1) cloth hole (5).
