Embodiment 1

[0026] Example one, see figure 1 , a cell freezing box, comprising a box 1, a test tube storage rack 2, a heat storage block 3 and an air hole 4.

[0027] The box 1 includes a bottom box 11 and an upper cover 12 covering the bottom box. The bottom case 11 is made of a heat insulating material. The bottom box 11 is a shell-like structure. The side wall of the bottom box 11 is provided with a first support step 111 and a second support step 112 . The first support step 111 is located above the second support step 112 . The outer surface of the bottom wall of the bottom box 11 is provided with supporting feet 113 . The support feet 113 are annular structures.

[0028] The upper cover 12 is made of heat insulating material. The upper cover 12 is a shell-like structure. The upper cover 12 is provided with an annular connecting tongue 121 . The connecting tongue 121 is tightly fitted with the side wall of the first supporting step 111 to be sealed together.

[0029] The tes...

Embodiment 2

[0033] Embodiment two, the difference with embodiment one is:

[0034] see figure 2, the upper end of the bottom box 11 is provided with an annular lower sealing surface 114 extending along the circumferential direction of the bottom box. The lower sealing surface 114 is provided with an annular ice sealing ring forming groove 115 extending along the circumferential direction of the lower sealing surface. An upper sealing surface 122 is provided on the lower end of the upper cover 12 corresponding to the lower sealing surface. A negative pressure forming cavity 5 is provided between the upper sealing surface 112 and the lower sealing surface 113 . There is only one negative pressure forming cavity 5 . The negative pressure forming cavity 5 is an annular structure extending along the circumferential direction of the lower sealing surface. The negative pressure forming cavity 122 is located inside the space enclosed by the ice sealing ring forming groove 115 (of course, it ...

Embodiment 3

[0037] Embodiment three, the difference with embodiment two is:

[0038] see Figure 4 , the air hole 4 is provided with a valve 6 with an adjustable opening. The valve 6 includes a valve seat 61 , a valve core fixing frame 62 and a push tube 63 which are sequentially distributed along the extending direction of the air hole. The valve seat 61 and the wall of the air hole 4 are hermetically connected together in the form of an integral structure. The valve seat 61 is provided with six rows of valve holes 64 . The sum of the number of valve holes and the opening area in each row of valve holes is equal. The valve core fixing frame 62 is provided with six rows of valve cores 65 . The number of valve cores in each row of valve cores 65 is equal to the number of valve holes in the corresponding row. The valve core holder 62 is supported in the air hole 4 by the valve opening spring 66 . The push tube 63 is screwed into the air hole 4 . The distances between the valve cores ...

Abstract

The invention relates to a storage device for freezing cells. A cell freezing box includes a box body; the box body is provided inside with a test tube storage rack and a heat storage block; the box comprises a bottom box and an upper cover; the bottom box and the upper cover are made of a heat insulating material; the heat storage block is made of metal; the outer surface of the bottom wall of the bottom box is provided with supporting a leg in a circular structure; and the top wall of the upper cover and the bottom wall of the bottom box are provided with pores communicating the internal and external space of the box. The invention provides a cell freezing container without addition of a liquid buffer medium, and solves problem of addition of liquid buffer medium of the cell freezing container of the prior art.

Description

technical field [0001] The present 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 viability. When freezing most cells, the freezing rate of cells is usually controlled at a rate of 1°C / min. Freezing and quick freezing are also different. [0003] Currently known cell cryopreservation boxes are all plastic shells with foam as a liner and isopropyl alcohol as a buffer medium. A cell freezing box is disclosed in a Chinese patent application No. 2011104362120, published on July 18, 2012, and entitled "A Multipurpose Cell Freezing and Recovery Container After Cryopreservation". The existing cell freezing boxes have the following shortcomings: when using in an ultra-low temperature refrigerator (usually -80 °C), if you directly touch the container with your hands, it is easy to cause frostbite; isopropyl a...
