[0002] Stem cells are a type of cell that has unlimited or immortal self-renewal capabilities and can produce at least one type of highly differentiated daughter cells. After stem cells are extracted, they need to be stored for future use. During the storage process, the collected stem cells are required to be placed in a liquid nitrogen tank for low-temperature storage, so that they can be preserved for a long time. Therefore, a stem cell storage device is needed.

[0003] In the stem cell storage we are currently using, the equipment will cause a large amount of internal gas to flow out when the stem cells are removed, and the hands of the staff will come into contact with the gas, which will affect the safety and effectiveness of the equipment when in use.

DETAILED DESCRIPTION

[0019] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0020] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0021] In the present invention, unless otherwise specified, directions such as "up" and "down" are usually relative to the directions shown in the drawings, or relative to the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "left" and "right" are usually relative to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directions are not used to limit the present invention.

[0022] like Figure 1-4 As shown, the present application provides a stem cell freezing storage device, including a tank body 1, an extraction component 2 is placed inside the tank body 1, a sealing cover 3 is installed on the top of the tank body 1, the extraction component 2 includes a placement cylinder 201 located in the tank body 1, an opening 210 is opened on the outer side of the placement cylinder 201, a sealing plate 202 is clamped inside the placement cylinder 201, a fixing plate 101 is fixedly connected to the top of the tank body 1, a threaded screw 102 is threadedly connected to the inner part of the fixing plate 101, a fixing rod 203 is fixedly connected to the top of the sealing plate 202, a moving groove 204 is opened at a position of the placement cylinder 201 near the fixing rod 203, a storage box 205 is placed inside the placement cylinder 201, a pressing plate 206 is clamped on the inner top of the placement cylinder 201, a threaded hole 207 is arranged on the outer side of the bottom of the placement cylinder 201, a fixing hole 208 is opened on the outer side of the bottom of the placement cylinder 201, and a positioning rod 209 is fixedly connected to the top of the storage box 205.

[0023] When the device is in use, stem cells are concentratedly placed in the storage box 205 for preliminary storage, and the storage box 205 is placed in the placement tube 201, and the placement tube 201 and the storage box 205 are placed in the tank body 1. At this time, the opening 210 on the outside of the placement tube 201 is not covered by the sealing plate 202, so that the gas inside the tank body 1 can contact with the placed stem cells. Finally, the sealing cover 3 is used to seal the tank body 1, so that the stem cells can be sealed and stored at low temperature through the whole device.

[0024] The pressing plate 206 includes a fixing ring 2061 , an elastic sheet 2062 is fixedly connected inside the fixing ring 2061 , a handle 2063 is fixedly connected to the top of the fixing ring 2061 , and a positioning bar 2064 is installed inside the fixing ring 2061 .

[0025] When the pressure plate 206 is in use, the starting position of the pressure plate 206 is at the inner top of the placement tube 201. At this time, the fixing ring 2061 is pressed downward by the handle 2063, so that the elastic sheet 2062 moves downward together with the fixing ring 2061. The elastic sheet 2062 is made of elastic material, so that the elastic sheet 2062 will be deformed after contacting the storage box 205, so that the elastic sheet 2062 can move downward smoothly. Through the downward movement of the elastic sheet 2062, the remaining gas inside the placement tube 201 will be squeezed and fall into the interior of the tank body 1, so that the gas can avoid excessive leakage and reduce contact with the hand, thereby improving the energy saving effect and safety of the equipment. Finally, after the fixing ring 2061 moves to the position of the fixing hole 208, the elastic part inside the positioning strip 2064 will squeeze the positioning strip 2064, so that the positioning strip 2064 will enter the position of the fixing hole 208, thereby avoiding the pressure plate 206 from falling as a whole.

[0026] The outer diameter of the threaded screw 102 is matched with the inside of the threaded hole 207, the outer side of the placement tube 201 is matched with the inside of the tank body 1, and the top of the storage box 205 is in contact with the top of the placement tube 201. The outer diameter of the threaded screw 102 is matched with the inside of the threaded hole 207, so that the placement tube 201 can be fixed after moving to the top of the tank body 1, thereby facilitating the subsequent work steps. The top of the storage box 205 is in contact with the top of the placement tube 201, so that the positioning rod 209 installed on the top of the storage box 205 can be smoothly placed on the top of the placement tube 201.

[0027] When it is necessary to take out the stem cells, the fixing rod 203 is moved inside the movable groove 204, so that the sealing plate 202 is driven to move, and the sealing plate 202 is moved to the opening 210 of the placement tube 201, so that the outside of the placement tube 201 can be sealed, and at the same time, the placement tube 201 is pulled upward as a whole, so that the threaded hole 207 is aligned with the threaded screw 102, and the threaded screw 102 is installed at the threaded hole 207 through the fixing plate 101, so that the placement tube 201 can be fixedly placed on the top of the tank body 1, and at this time, the opening 210 on the outside of the placement tube 201 is sealed by the sealing plate 202, and the pressing plate 206 blocks the top of the placement tube 201, so that the excess gas inside the tank body 1 will not be completely discharged to the outside, so as to reduce the loss of gas and prevent the gas from contacting the hands of the staff, and finally the pressing plate 206 can be used to squeeze the remaining gas inside the placement tube 201, so that the remaining small amount of gas can re-enter the interior of the tank body 1, thereby reducing gas leakage.

[0028] The fixing rod 203 extends out of the top of the placing tube 201, and the outer side of the fixing rod 203 is adapted to the inside of the movable groove 204. An opening 210 is provided on the outer side of the placing tube 201, so that after the placing tube 201 is placed into the tank body 1, the gas can come into contact with the stem cells stored in the placing tube 201. The outer side of the fixing rod 203 is adapted to the inside of the movable groove 204, so that the fixing rod 203 can move in the position of the movable groove 204, thereby driving the overall movement of the sealing plate 202.

[0029] Because the elastic sheet 2062 is a deformable elastic structure, the elastic sheet 2062 can be deformed after coming into contact with the storage box 205 , so that the entire pressing plate 206 can smoothly reach the bottom of the placement tube 201 .

[0030] An elastic member is installed on one side of the positioning bar 2064 , and the outer diameter of the positioning bar 2064 is adapted to the inside of the fixing hole 208 . The elastic member is installed on one side of the positioning bar 2064 so that the positioning bar 2064 can rebound after contacting the fixing hole 208 .
