AI Technical Summary
Existing contactless blood thawing devices have the problem of uneven heating inside the blood bag, resulting in slow thawing speed and uneven blood concentration after thawing.
A rotating disk and an incomplete gear structure are used to drive the placement plate to swing back and forth. Combined with a heater, it swings back and forth above the blood bag to ensure uniform heating of all parts. The reciprocating motion of the blood bag is achieved through the motor-driven rotating disk and gear meshing. At the same time, a water-absorbing sponge is used to collect moisture during the thawing process.
The blood thawing speed is accelerated and the concentration is uniform after thawing, which improves the thawing efficiency and reduces the risk of contamination.

[0031] Working principle: When using the non-contact blood thawing device, first place the blood bag on the placement plate 9 so that the blood bag is located between the two sets of isolation layers 10, thereby fixing the blood bag to a certain extent. Then place the absorbent sponge 13 into the device body 1 so that the device body 1 is located below the leakage groove 11. Then turn the door 20 so that the fixing block 1 23 is located on the side of the fixing block 2 24 and the limit column 27 is located in the middle of the fixing block 1 23. Then turn the knob 2 5, drive the threaded rod 26 and the limit column 27 to rotate, so that the threaded rod 26 is threadedly connected to the fixed block 24, and the limit column 27 is rotated to a vertical state, so that the limit column 27 is attached to one side of the fixed block 1 23, and then the motor 2 14 is turned on, so that the output end of the motor 2 14 drives the rotating shaft 15 to rotate, and the bottom end of the rotating shaft 15 drives the connecting plate 16 to rotate on the fixed shaft 18, thereby driving the auxiliary block 17 and the heater 19 to swing, and the heater 19 is turned on, so that the heater 19 is heated to the blood.

The swing rod 5 swings while driving the incomplete gear 7 and the rack 8 to engage and rotate, driving the rack 8 to slide in the device body 1, thereby driving the blood bag on the placement plate 9 to swing back and forth. At the same time, the slide bar 12 slides in the device body 1, thereby ensuring the concentration of the blood bag after thawing. At this time, the water generated by the thawing blood bag falls from the leakage groove 11 to the top of the absorbent sponge 13, and is then fully absorbed by the absorbent sponge 13. The staff can observe the thawing of the blood in the device body 1 through the transparent glass 21. After the thawing is completed, the limit column 27 is rotated in the opposite direction to move it away from the fixed block 23. The frozen blood bag can be taken out, and then the absorbent sponge 13 is taken out, drained, and reused.
