[0093] Reference Figure 2 、 Figure 6 、 Figure 11 In the embodiment, a plurality of control buttons are arranged on the operation panel 35, wherein the control buttons include: an up key and a down key for controlling the up or down of the box body 1; a power-assisted start-stop switch for controlling the start or stop of the hub motor 34, and a speed-up key and a speed-down key for controlling the speed of the power assistance; during the transfer process, the power-assisted function of the rear wheels 39 is turned on through the power-assisted start-stop switch, at this time, the power module supplies power to the hub motor 34, and the hub motor 34 rotates, so as to provide power assistance to the medical personnel when pushing the box body 1 and the mobile base 3, and the rotation speed of the hub motor 34 is controlled through the speed-up key and the speed-down key, so as to avoid the problem of too fast power assistance speed; when the frozen semen specimen in the box body 1 and the liquid nitrogen transfer box with the frozen semen on the placing plate 11 are transferred into / out of the ten-thousand-level laboratory, the up key and the down key are used to control the up or down of the box body 1 until the appropriate height is reached; then the parking key can be turned on, so that the position of the mobile base 3 is relatively fixed, so as to avoid the translation of the box body 1 during the transfer process; through the above arrangement, the transfer of the frozen semen between the elevator and the corridor in the hospital is convenient and safe, and the quality of the frozen semen and the safety of the medical staff are guaranteed throughout the process.

[0094] Method for using the application:

[0095] 1. First, place the liquid nitrogen transfer box in which the semen is frozen at-196C° state on the placing plate of the box body, and in the fixed area, wherein the liquid nitrogen transfer box is fixed by a plurality of first elastic elements and second elastic elements after being placed, so as to avoid the liquid nitrogen transfer box from falling off the placing plate during the transfer process;

[0096] 2. A blue ice plate is pre-installed in the groove in the box body cavity, so that the temperature in the box body cavity is maintained at-20C°; the frozen semen specimen is placed in the box body, so as to maintain the frozen semen specimen in a solid state at all times;

[0097] 3、By applying force to the push handle, the base is moved by a pair of front wheels and a pair of rear wheels to achieve short-distance transfer of frozen semen in the hospital; the power-assisted start-stop switch on the operation panel is turned on to start the power-assisted function of the rear wheels, and the speed-up key and the speed-down key are used to control the power-assisted speed of the rear wheels, so that the base is more easily pushed during the transfer of frozen semen, thereby reducing the physical labor of medical personnel and achieving short-distance and efficient transportation of frozen semen in the hospital.

[0098] 4、When the box containing frozen semen specimens needs to be transferred through the floor transfer window of the ten-thousand-level laminar flow laboratory, the lifting key and the lowering key on the operation panel are operated to adjust the height of the box to the appropriate height, so that the frozen semen in the liquid nitrogen transfer box and the frozen semen specimens in the box can be transferred in / out of the ten-thousand-level laminar flow laboratory.

[0099] The above description of the embodiments is only for the purpose of understanding the present application. It should be noted that those skilled in the art can make several improvements to the present application without departing from the principles of the present application, and these improvements will also fall within the scope of protection of the claims of the present application.
