Title: Organ storage container
Inventor: TORAI SHINJI
IPC: A61B46/20
Filed: 2019-09-11
Abstract: To provide a medical appliance capable of further suppressing temperature rise of an organ in implantation of an organ to a recipient, and suppressing hindrance to an operation performed by a surgeon.SOLUTION: An organ storage container 1 has a flexible bag-shaped trunk 20 having an opening 30. In a state of having no load, a maximum width D4 of the opening 30 is smaller than a maximum width D1 of the trunk 20. The opening 30 can be extended to a state in which the maximum width of the opening 30 is greater than a maximum width D4 of the trunk 20. Accordingly, the organ storage container 1 covers a surface of an organ along a surface of the organ. Therefore, when arranging the organ in a body cavity of a recipient, the organ storage container 1 does not extend to a surrounding of the organ, and thus hindrance to an operation performed by a surgeon during surgery can be suppressed. In addition, since the organ storage container covers a majority of the organ, temperature rise of the organ can be suppressed.SELECTED DRAWING: Figure 3
