Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "disposed," "connected," and the like are to be construed broadly, and for example, "connected" may be either fixedly connected or detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

With reference to fig. 1 and 2, a sealed cryopreservation bag comprises a bag body 1, wherein a liquid injection port 2 and a liquid outlet 3 are arranged on the bag body 1, the liquid injection port 2 is connected with a liquid injection pipe 4, the outer diameter of the head of the liquid injection pipe 4 is large, and the end face, far away from the bag body 1, of the liquid injection pipe 4 is a plane perpendicular to the length direction of the liquid injection pipe 4 so as to be connected with other pipelines conveniently. Annotate the head of liquid pipe 4 and be equipped with soft sealed diaphragm 5, sealed diaphragm 5 and the hole of annotating liquid pipe 4 are fixed or an organic whole is connected, and wherein, annotate liquid 4 head and can adopt the same material with sealed diaphragm 5, like materials such as EVA, because the material is the same, both integrated into one piece only through once moulding plastics can, save the process, practiced thrift the processing cost. The head of the liquid injection pipe 4 can also be made of hard materials such as plastics, although the processing procedures are increased, the hard materials are more stable when being connected with other pipelines, and the liquid injection effect is better.

Sealing diaphragm 5 also can set up a plurality ofly in order to increase sealed effect, and especially sealed diaphragm 5 of the top is because direct damage when contacting with the external world, but has also played the guard action to other sealing diaphragm 5 of inlayer simultaneously, has certain clearance between the adjacent sealed diaphragm 5 to the condition of breakage appears in the prevention simultaneously.

One end an organic whole that bag body 1 was kept away from to hole 6 is connected with a horn mouth inclined plane 7, and the major diameter end of horn mouth inclined plane 7 is connected with notes liquid pipe 4 an organic whole, and the path end is located notes liquid pipe 4, firstly plays the guide effect, and on the other hand also plays certain fixed action to other pipelines of being connected with notes liquid pipe 4.

During liquid injection, the needle 11 is used for puncturing the sealing membrane 5, liquid is injected into the bag body 1 through the needle, after the liquid injection is completed, the heat seal sealing position 10 is subjected to heat seal, the joint of the heat seal part and the position which is not subjected to heat seal becomes quite fragile, and the liquid injection pipe above the heat seal sealing position 10 is torn off. When liquid is discharged, the bag body 1 is hung upside down through the hanging hole 9, and the twist-off plug 8 is unscrewed to be communicated with other pipelines to realize liquid discharge.

The utility model discloses sealing performance compares the tradition and freezes the bag and has great promotion, freezes the difficult quilt of depositing bag inner cell liquid and pollute to the mode of puncture moves liquid filling operation very conveniently, and spreading value is high.
