PROBLEM TO BE SOLVED: To provide a thawing device and a thawing method which is capable of quickly administering a liquid object of biological origin to a living body after thawing a frozen matter of biological origin.SOLUTION: A thawing device 10 thaws a frozen matter of biological origin 14 contained in a container 12. The thawing device 10 comprises: a warming unit 42h which warms the container 12; and a pressing part 42p which presses the container 12 to push a liquid object of biological origin 14L obtained by thawing the frozen matter of biological origin 14 out of the inside of the container 12.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2019,JPO&INPIT【課題】生体由来凍結物の融解後に生体由来液状物を迅速に生体に投与することができる融解装置及び融解方法を提供する。【解決手段】融解装置10は、容器12内に収容された生体由来凍結物14を融解する。融解装置10は、容器12を加温する加温部42hと、容器12を押圧して、生体由来凍結物14が融解した生体由来液状物14Lを容器12内から押し出す押圧部42pとを備える。【選択図】図3
