Detailed Description

In order to make the objects, technical solutions and advantageous effects of the present utility model more apparent, preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate understanding of the skilled person.

As shown in fig. 1-3, the improved cell freezing bag comprises a storage bag 1, a box body 2, a liquid inlet pipe 3 and a liquid outlet pipe 4. The storage bag 1 is of a quadrangular structure with arc edges, when cells are taken out, the cells in the bag can flow out along the arc edges, and the problem that the traditional rectangular storage bag is left at the edges of the storage bag 1 to cause resource waste due to the edges of the storage bag is avoided. A placing groove 5 corresponding to the structure of the storage bag 1 is arranged in the box body 2, and the storage bag 1 is placed in the box body 2. The box body 2 comprises an upper box body 6 and a lower box body 7 which are symmetrical to each other, one side of the upper box body 6 is hinged with one side of the lower box body 7 through a hinge 8, and the other side of the upper box body 6 is fixed through a buckle 9.
