[0022] During cleaning, the water source is injected into the fixed hollow bracket 41 through the fixed long tube 111 by connecting the input end of the water pump 11 to the water pipe, and then the water is filled into the inner cavity of the bottle placement box 43 through the base box 42, and the glass movable door 2 is used to facilitate observation of the cleaning condition inside the cleaning box 1.

[0023] like Figure 3 , Figure 4 As shown, a plurality of rotating motors 431 are fixedly installed in a circular array at the eccentric position of the bottom of the inner wall of the bottle body placement box 43, the output shafts of the plurality of rotating motors 431 all penetrate the top of the bottle body placement box 43 and are fixedly installed with rotating rods 432, cleaning brushes 433 are fixedly installed on opposite sides of the outer walls of the plurality of rotating rods 432, a sponge head 434 is fixedly installed on the top of the rotating rod 432, and water spray heads 435 are provided on the front and rear sides of the plurality of rotating rods 432, and the water spray heads 435 are all fixedly connected with the top of the bottle body placement box 43, and the flushing clamping mechanism 5 includes an electric push rod 51, the electric push rod 51 is fixedly installed at the center of the top of the inner wall of the cleaning box 1, and a clamping hollow disk 52 is fixedly installed at the bottom output end of the electric push rod 51. A water delivery hose 112 is fixedly connected to the upper left output end of the water pump 11. The output end of the water delivery hose 112 penetrates the inner cavity of the cleaning box 1 and is fixedly connected to the top of the clamping hollow disk 52.

The plurality of extrusion cylinders 53 are respectively located above the plurality of rotating rods 432, and the bottoms of the plurality of extrusion cylinders 53 are fixedly connected with flushing ports 54;

[0024] When it is necessary to clean the bottle of hematopoietic stem cells of the umbilical cord blood after extraction and thawing, the bottles are inverted one by one and inserted into the rotating rod 432 on the top of the bottle placement box 43, and the soft characteristics of the sponge head 434 and the cleaning brush 433 are used to temporarily fix the bottle under the squeezing of the sponge head 434 and the cleaning brush 433, and the cleaning brush 433 and the sponge head 434 are made to fit tightly against the inner wall of the bottle, and the bottle placement box 43 filled with water is used to rinse the inner wall of the bottle through the water spray heads 435 on the front and rear sides of the rotating rod 432, and at the same time, the electric push rod 51 is started to drive the clamping hollow disk 52 to descend, and the multiple squeezing cylinders 53 at the bottom of the clamping hollow disk 52 can be used to squeeze the top of the bottle on the outer side of the multiple rotating rods 432, so that the bottle is firmly fixed, and at the same time, the rotating motor 431 in the inner cavity of the bottle placement box 43 is started.

[0027] The working principle of the cleaning device after thawing of umbilical cord blood hematopoietic stem cells will be described in detail below.

[0028] like Figure 1-5As shown, when it is necessary to clean the bottle of hematopoietic stem cells extracted from the thawed umbilical cord blood, the bottles are inverted one by one and inserted into the rotating rod 432 on the top of the bottle placement box 43, and the soft characteristics of the sponge head 434 and the cleaning brush 433 are used to temporarily fix the bottle under the squeezing of the sponge head 434 and the cleaning brush 433, and the cleaning brush 433 and the sponge head 434 are made to cling to the inner wall of the bottle.

At the same time, the electric push rod 51 is started to drive the clamping hollow disk 52 to descend, and the top of the bottle covered on the outer side of the plurality of rotating rods 432 can be squeezed by using the plurality of squeezing cylinders 53 at the bottom of the clamping hollow disk 52, so that the bottle is firmly fixed. The bottle body is firmly fixed, and the rotating motor 431 in the inner cavity of the bottle body placement box 43 is started at the same time to drive the rotating rod 432 to drive the cleaning brush 433 and the sponge head 434 to rotate and clean the inner wall of the bottle body, and cooperate with the water spray head 435 to rinse the inner wall of the bottle body, so that the inner wall of the bottle body is effectively cleaned. At the same time, when the outer wall of the bottle body needs to be cleaned, the electric push rod 51 drives the clamping hollow plate 52 to rise, releases the clamping fixation of the bottle body, and uses the water delivery hose 112 connected to the other output end of the water pump 11 to inject water into the inner cavity of the clamping hollow plate 52, and uses the hollow extrusion cylinder 53 to flush the outer wall of the bottle body below through the flushing port 54. At this time, since the bottle body is no longer squeezed and fixed by the extrusion cylinder 53, the cleaning brush 433 can be used to squeeze the inner wall of the bottle body under the rotation of the rotating rod 432, so that the bottle body is driven to rotate, so that the outer wall of the bottle body is evenly rinsed. Because there is no umbilical cord blood hematopoietic stem cell residue on the outer wall of the bottle body, a simple rinse is sufficient.
