Abstract: A medical container includes: a container body, a mouth section through which liquid can enter and exit, a proximal-end opening, and a proximal-end edge portion surrounding the proximal-end opening; a plug body that seals the mouth section; a bag body having a bag-like shape and including an edge portion that is tightly fixed to the proximal-end edge portion and seals the proximal-end opening, and a reversing part which is surrounded by the edge portion, has flexibility, and is reversed inside/outside; and a space surrounded by the container body, the plug body and the bag body. The reversing part is reversed inside/outside when the liquid enters and exits the space through the mouth section, whereby the reversing part can take a first state in which the reversing part expands toward a distal end side, and a second state in which the reversing part expands toward the proximal end side.

Abstract: A liquid medicine storage container has a container body and a medicine stored in the container body. The container body includes a first space provided on the distal end, into which a liquid is injected, a second space provided more to the proximal end than the first space, for storing the medicine, and at least one guide passage that communicates the first space and the second space and that guides a liquid injected from the first space to an inner surface of the second space. The container body is configured so that the liquid guided to the inner surface is supplied to the medicine by flowing along the inner surface. A plurality of guide passages is arranged with intervals therebetween along a circumferential direction of the container body.

Abstract: A connector assembly is provided with a first connector equipped with a first connector body, a hollow needle supported on the inner side of the first connector body and having a side hole (53), and a first sealing member having a head which can be pierced through by the hollow needle; a second connector equipped with a second connector body and also with a second scaling member which can, when in a mounted state, be pierced through by the hollow needle; and a close-contact maintaining means which can, when in the mounted state, maintain that the head and the second sealing member are in close contact with each other. When the second connector becomes pulled out of the first connector, the head and the second sealing member are held in close contact with each other by the close-contact maintaining means until the hollow needle is pulled out of the second scaling member.
