[0027] The embodiments of the present utility model will be further described below with reference to the accompanying drawings.

[0028] Embodiment:

[0029] As Figures 1 - 5 shown, a plasma thawing box includes a box body 10, a bracket 20, a turntable 30 and a blood bag fixing member 40. A water tank 11 is provided at the top of the box body 10. A heating device and a power supply for heating the water tank 11 are provided inside the box body 10. The bracket 20 is provided on one side of the water tank 11 at the top of the box body 10 and is in a right-angled shape. The end of the bracket 20 extends to the middle of the top of the water tank 11, and a motor 21 is provided at this end. The power supply supplies power to the heating device and the motor 21 respectively; the turntable 30 is provided in the water tank 11. A connection hole 33 is provided in the middle of the turntable 30 and is connected to the shaft of the motor 21. To ensure stable connection, a connection block can be provided at the end of the shaft of the motor 21, and threaded holes are provided on both sides of the connection block. Through holes matching the threaded holes are provided on both sides of the connection hole 33 of the turntable 30, and bolts can pass through the threaded holes to connect the through holes; the number of blood bag fixing members 40 is multiple, and they are arranged in a circular array on the edge of the turntable 30, including a bracket and a cover plate 44. The bracket includes an intermediate plate 41, side plates 42 and a bottom plate 43. The intermediate plate 41 is arranged vertically. The side plates 42 are provided on both sides of the intermediate plate 41. The bottom plate 43 is vertically provided at the bottom side of the intermediate plate 41 for supporting the blood bag. A hinge member 49 is provided between the bottom side of the cover plate 44 and the bottom plate 43 to enable the two to be hinged, and a locking member is provided between the cover plate 44 and the bracket. A horizontal flange 45 is provided at the top of the hinged intermediate plate 41, and an insertion rod 46 is provided at the bottom of the flange 45. An insertion hole 32 matching the insertion rod 46 is provided on the connection head 31. When the turntable 30 rotates, the blood bag fixing member 40 does not interfere with the inner wall of the water tank 11.

[0030] The working principle of the above technical solution is as follows:

[0031] During use, the blood bag fixing member 40 can be first removed from the turntable 30, the cover plate 44 is opened, the blood bag is placed on the bracket and then the cover plate 44 is closed. The insertion rod 46 passes through the insertion hole 32, and the flange 45 fits against the turntable 30 to realize the connection of the blood bag fixing member 40. Clear water is injected into the water tank 11, and then the heating device is started to keep the blood bag in the water tank 11 at a constant temperature, and the motor 21 is started to perform centrifugal thawing operation on the blood bag. After a period of time, the motor 21 can be turned off, and individual blood bag fixing members 40 can be removed separately to observe the thawing situation, which is convenient for further thawing operation.

[0032] In another embodiment, as Figure 3 shown, connectors 31 extend uniformly along the edge of the turntable 30. The angle between the connector 31 and the corresponding tangent of the turntable 30 is 45°. A plurality of brackets are detachably connected to the same side of the plurality of connectors 31.

[0033] On the premise of maintaining a good centrifugal effect, the connectors 31 on the edge of the turntable 30 are conducive to the compact arrangement of the blood bag fixing member 40 and save space.

[0034] In another embodiment, as Figures 4 - 5 shown, a number of water holes 47 are provided on the middle plate 41, the side plate 42, the bottom plate 43 and the cover plate 44 respectively.

[0035] The water holes 47 on the brackets and the cover plate 44 are conducive to the blood bag contacting the warm water evenly and sufficiently, which is conducive to the plasma thawing.

[0036] In another embodiment, the locking member can be a torsion spring, which is arranged at the hinge joint of the cover plate 44 and the bottom plate 43. It is convenient for the cover plate 44 to be in a relatively stable closed state for a long time when no external force is applied or the external force applied is less than the elastic force of the torsion spring.

[0037] In another embodiment, as Figures 4 - 5 shown, a pull ring 48 is provided at the top of the folded edge 45. The top side of the cover plate 44 is bent away from the middle plate 41, and a pull hole can be provided on the bent part. The pull ring 48 is convenient for lifting the blood bag fixing member 40 to separate it from the turntable 30, and the pull hole is convenient for opening the cover plate 44.

[0038] The above-described embodiments only represent the specific implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
