This invention relates to the field of embryo resuscitation technology and discloses an auxiliary warming device for frozen embryo resuscitation, including a collection plate. A fixing ring is fixedly connected to the side wall of the collection plate, and a forward threaded groove is formed on the side wall of the fixing ring. The cover plate drives the separator ring to rotate clockwise through the contact rod and the fixing plate. Since the reverse threaded groove rotates in the opposite direction to the forward threaded groove, the rotating ring will move upward at this time. The upward rotating ring will drive the separator ring to move upward synchronously, so that the through hole gap coincides with the flow hole. At this time, the new solution on the outer wall of the separator ring flows downward through the flow hole and the through hole gap. Finally, the new solution mixes with the solution inside the collection plate. At this time, the pressure of the dripping will be absorbed by the top of the fixing ring and will not directly contact the solution inside the collection plate. When the operator twists the cover plate to close it, the flow hole and the through hole gap will coincide, and the new solution will mix with the solution inside the collection plate, effectively reducing the damage to the outer wall of the embryo cell membrane when injecting the new solution.
