Embodiment 2

[0039] Embodiment two, see Figure 4 , the difference from the first example is that the base 1 includes a base inner core 13 and three base sheathing layers 14 . The base cover layer 14 is a cylindrical structure with only an open upper end. The three base sheathing layers 14 are sheathed together sequentially. The base inner core 13 is installed in the innermost base sleeve layer among the three base sleeve layers 14 . The connection hole 11 is provided on the upper end surface of the inner core 13 of the base. The base segment 41 is disposed on the upper end surface of the base inner core 13 . The sequence mark of the cell storage hole is arranged on the upper end surface of the inner core 13 of the base. The upper cover 2 includes an upper cover inner core 22 and three upper cover sleeve layers 23 . The upper cover layer 23 is a cylindrical structure with only the lower end open. The base sheathing layers 23 are sheathed together sequentially. The inner core 22 of t...

Embodiment 3

[0042] Embodiment 3 is different from Embodiment 2 in that: the base layer and the upper cover layer both have only one layer.

[0043] see Figure 6 , also includes a vacuum pump 7, a translation mechanism 8 and a control unit 9.

[0044] The cell storage hole 4 includes a fixed section 43 of the cell storage tube and a suspended section 44 of the cell storage tube. The suspended section 44 of the cell storage tube is composed of a base section 41 and an upper cover section 42 . The cell storage tube fixing section 43 is located in the base section 41 .

[0045] The vacuum pump 7 is located in the connection hole 11 . The base section 41 is connected together through the gas pipe 45 and the inlet 71 of the vacuum pump. A control valve 46 is provided on the gas pipe 45 . The control valve 46 is used to control the opening and closing of the gas pipe 45 . In this embodiment, one vacuum pump is used for all the cell storage wells 4. Obviously, it is also possible to use a ...

Abstract

The present invention relates to an apparatus for freezing storage cells. The cell freezing box comprising a base and an upper cover covering on the base, wherein the upper end surface of the base is provided with a connection hole, a heat storage block is held in the connection hole, the lower end surface of the upper cover is provided with a connection head capable of forming an inserted and pulled connection in the connection hole, the base and the upper cover are connected through the connection head matching connection hole, and are manufactured from the same thermal insulation material, the heat storage block is made from a metal material, and the connection position of the base and the upper cover is provided with cell storage holes around the connection hole. The present invention provides a cell freezing container without addition of a liquid state buffer medium, such that the problem that the existing cell freezing container requires addition of the liquid state buffer medium is solved.

Description

technical field [0001] The invention relates to a device for storing cells for freezing, in particular to a cell freezing box. Background technique [0002] When freezing cells, if the freezing rate is too fast or too slow, the cells will lose their activity. When freezing most cells, the freezing rate of cells is usually controlled at a rate of 1°C / min. Temporary freezing and quick freezing are also different. [0003] Currently known cell cryopreservation boxes are all plastic shells, with foam as a liner inside and isopropanol added as a buffer medium. A cell freezing box is disclosed in the Chinese patent application No. 2011104362120, the publication date being July 18, 2012, and the patent document titled "A Multipurpose Cell Freezing and Recovery Container After Freezing Storage". The existing cell freezing boxes have the following disadvantages: when using in an ultra-low temperature refrigerator (usually -80°C), if you directly touch the container with your ha...
