no. 1 Embodiment approach 〕

[0054] One aspect of the present invention relates to a device that is detachably attached to a container for storing grafts, and the device includes: a cover member for sealing the container; The annular member forming the first space forms the second space between the lid member and the inner surface of the container.

[0055] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

[0056] First, a first embodiment of the present invention will be described.

[0057] figure 1 It is a conceptual diagram of the device 1 according to the first embodiment of the present invention, figure 2 for figure 1 A cross-sectional view of the device 1 is shown. It should be noted that in each figure of the present application, for ease of description, the size of each component is appropriately enlarged, and each component in the illustration does not represent an actual size.

[0058] Such as figure 1As shown, the dev...

no. 2 Embodiment approach 〕

[0082] Such as image 3 As shown, the clip 7 according to this embodiment includes a base member 8 and a cover member 9 . The clip 7 can press and hold the device 1 including the container 2 (not shown) and the lid member 3 (not shown) for sealing the container 2 from the top and bottom.

[0083] Both the base member 8 and the cover member 9 have a circular shape, and can appropriately press the device 1 from above and below. The base member 8 includes an opening portion 81 , a bottom portion 82 , a screwing portion (engagement portion) 83 , a mounting portion 84 , and a protrusion portion 85 . In this embodiment, the engagement is screw engagement. The mounting portion 84 has a mounting surface on which the container 2 can be mounted on the upper surface, and an opening 81 is provided in the center. The mounting portion 84 has an annular protrusion 85 (slender ridge) surrounding the lower end of the container 2 when the container 2 is mounted on the mounting surface, and c...

no. 3 Embodiment approach 〕

[0090] Next, a third embodiment of the present invention will be described. Hereinafter, differences from the second embodiment will be described in detail, and descriptions of the same matters will be omitted. It should be noted that, in each figure of the present application, in order to facilitate the description, the size of each component is appropriately enlarged, and each component in the illustration does not represent the actual size.

[0091] Such as Figure 4 As shown, the clip 7A according to this embodiment includes a base member 8A and a cover member 9A. In this embodiment, the base member 8A further includes a protruding wall 86 , a groove portion 87 and a notch portion 88 . The protruding wall 86 is a plurality of walls protruding beyond the height of the container 2 from the mounting portion 84 provided outside the protruding line portion 85 . A groove 87 is provided on the lower surface of the bottom portion 82 of the base member 8A to prevent the base mem...

Abstract

The purpose of the present invention is to provide a device which can efficiently establish a liquid-tight state with a simple operation. The present invention relates to a device to be used in a state of being detachably attached to a container for storing a graft, the device comprising: 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 the inside surface of the container.

Description

technical field [0001] The present invention relates to devices for transferring grafts. Background technique [0002] In recent years, the development of new regenerative medicine has been promoted as a solution to the treatment of severe heart failure. As an example, for severe myocardial infarction and the like, a method of applying a sheet-shaped cell culture produced using a temperature-responsive culture dish to which tissue engineering is applied to the surface of the heart is being attempted. Methods using sheet cell cultures enable safe transplantation of large numbers of cells over a wide range, for example, for myocardial infarction (including chronic heart failure with myocardial infarction), dilated cardiomyopathy, ischemic cardiomyopathy, with systolic function It is particularly useful in the treatment of cardiac disorders (eg, left ventricular systolic dysfunction), such as heart failure, especially chronic heart failure. [0003] When such a sheet-shaped c...
