Abstract: A device for stably maintaining the shape of a fragile object in a liquid includes a container for accommodating the fragile object, a lid member for sealing the container, and a protecting member. The device is configured to form a liquid-tight space by covering a liquid surface in the container which accommodates the fragile object and the liquid with the protecting member and further covering the protecting member and an open portion of the container with the lid member.

Abstract: A holding tool is configured to efficiently and reliably enable a close contact between a container and a lid with a simple mechanism and a simple operation. The holding tool is configured to be used together with a container and a lid for the container to sandwich the container and the lid. The holding tool includes a base on which the container is placed, and a cover configured to cover the lid. The base and the cover each have an opening at a central portion and are configured to engage with each other to press and sandwich the container and the lid upward and downward.

Abstract: A device for transporting objects such as a graft is configured to efficiently establish a liquid-tight state with a simple operation. The device is to be used in a state of being detachably attached to a container for storing a graft, the device including: a lid member for sealing the container; and an annular member for forming a first space by being interposed between the lid member and the container, wherein a second space is formed between the lid member and an inside surface of the container.

Abstract: An object of the present invention is to provide a cell sheet embedding agent, which makes it possible to stably transport a cell sheet at the time of transport at a low temperature and to collect the cell sheet from the cell sheet embedding agent in a simple manner after being transported, a cell sheet-containing composition, and a kit. According to the present invention, there is provided a cell sheet embedding agent containing a polypeptide represented by the following Formula 1, in which in a case where a molecular weight distribution of the polypeptide is measured, a peak area of a maximum molecular weight is equal to or greater than 80% of the total peak area of all molecular weights. A-[(Gly-X—Y)n]m—B??Formula 1: In the formula, X and Y each independently represent an amino acid, m is an integer of 2 to 10, n is an integer of 3 to 100, and A and B each represent any amino acid or any amino acid sequence.

Abstract: An object of the present invention is to provide a laminate containing a cell sheet which has hardness and is easy to handle at the time of transplantation or transport, an agent for treating cardiac diseases using the laminate, and a film for being laminated on a cell sheet. According to the present invention there are provided a laminate including a biocompatible polymer film having a density of 500 ?g/cm2 to 10 mg/cm2 and a cell sheet disposed on at least one surface of the biocompatible polymer film, an agent for treating cardiac diseases using the laminate, and a film for being laminated on a cell sheet.

Abstract: An operating device for a disconnector includes a drive unit, a Geneva mechanism, and a wire. The drive unit includes a forwardly and reversely rotatable motor serving as a drive source for driving a movable contactor of the disconnector, a power source supplying power to the motor, and a first pulley connected to a rotary shaft of the motor, and is disposed apart from the disconnector. The Geneva mechanism includes a second pulley that rotates in the same direction as the first pulley with the rotation of the first pulley, and a driven wheel that is intermittently driven while the second pulley rotates and that is provided with a rotary shaft connected to the movable contactor, and is attached to the disconnector apart from the drive unit. Further, as a flexible rotational force transmission member, a wire is stretched between the second pulley and the first pulley.
