DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4A storage device for stem cell culture fluid comprises an insulated box body 1 and two insulated box doors 3, the inner wall of the insulated box body 1 is fixedly connected with a partition 19, the inner bottom of the insulated box body 1 is equipped with two mounting frames 8 through two rotating shafts 12, a sterilization mechanism for eliminating bacteria on the surface of the container is arranged in the insulated box body 1, the sterilization mechanism comprises a plurality of ultraviolet lamps 5 arranged on the two inner walls of the insulated box body 1 and the two side walls of the partition 19, a placement ring 6 is fixedly connected to the inner wall of the mounting frame 8, a placement plate 7 is arranged in the placement ring 6, and a plurality of ice packs 14 are arranged at the inner bottom of the insulated box body 1.

[0022] A driving mechanism for driving the rotating shaft 12 to rotate is provided in the incubator body 1, and the driving mechanism includes a motor 11 fixedly connected to the bottom of the incubator body 1. The model of the motor 11 is 1FK7101-2AC71-1RH1. The output shaft of the motor 11 is fixedly connected to the second gear 10, and the side wall of the rotating shaft 12 is fixedly connected to the first gear 9 meshing with the second gear 10. The teeth of the second gear 10 and the first gear 9 are not shown in the diagram, and the meshing details are not shown in the diagram. The incubator body 1 is provided with a control panel 4, and the side wall of the incubator door 3 is provided with a thermostat 18 and a temperature sensor 20. The thermostat 18 model is AI-207 economical intelligent thermostat, and the temperature sensor 20 model can be ARTM-Pn wireless temperature measuring device.

[0023] In the utility model, both side walls of the thermal insulation box body 1 are provided with heat sinks 17, and the side walls of the heat sink 17 are provided with heat conductive sheets 15 through refrigeration sheets 16, the heat conductive sheets 15 are connected to the cold ends of the refrigeration sheets 16, and the heat sink 17 is connected to the hot ends of the refrigeration sheets 16. The heat sink 17 dissipates the hot ends of the refrigeration sheets 16 into the air, and the heat conductive sheets 15 absorb the internal heat of the thermal insulation box into the refrigeration sheets 16, so that the temperature in the thermal insulation box will not rise even after the ice packs 14 melt during long-term transportation of the equipment.

[0024] In the utility model, two power boxes 21 are installed on the side walls of the incubator body 1, so that the incubator body 1 can be used without being plugged in, thereby improving the practicality of the device. A handle 2 is fixedly connected to the upper end of the incubator body 1 to facilitate moving the device.

[0025] In the utility model, two placement frames 13 are fixedly connected to the bottom of the thermal insulation box body 1, which can limit the ice pack 14 to prevent the ice pack 14 from moving randomly due to the tilt of the thermal insulation box during transportation. The inner circle cross-section of the placement ring 6 is a convex structure, which allows the placement ring 6 to carry the placement plate 7 without the need for a threaded connection, making it easier to take out the placement plate 7.

[0026] In the initial state, the number of the placement plates 7 is the same as the number of the placement rings 6 .

[0027] When in use, the placement plate 7 is taken out, the stem cell culture tube is inserted into the through hole of the placement plate 7, and then put back into the placement ring 6, and then the two insulation box doors 3 are closed, and the multiple ultraviolet lamps 5 are started, so as to sterilize the stem cell culture tube in the insulation box body 1, so as to prevent the stem cell culture tube from breeding bacteria during the long transportation process or the stem cell culture tube from carrying bacteria when it is placed, and thus ensure the hygienic condition of the stem cell culture tube when it is stored;

[0028] In addition, by starting the motor 11, the output shaft of the motor 11 drives the rotating shaft 12 to rotate through the second gear 10 and the first gear 9, and the rotating shaft 12 drives the multiple placement plates 7 to rotate, so that the stem cell culture tubes can be rotated, making the sterilization of a large number of stem cell culture tubes more careful and rapid.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and practical concept of the present invention, which should be covered by the protection scope of the present invention.
