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 sealing 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 sealing member.

Description

technical field [0001] The present invention relates to connector assemblies. Background technique [0002] Usually, anticancer agents, immunosuppressants, and other drugs that are dangerous if medical workers accidentally touch them are contained in a powder state in a vial container (medicine storage container) whose mouth is sealed with a rubber stopper. [0003] When taking out medicines from such vial containers, the following operations are performed. [0004] First, the mouth of the vial container and the mouth of the syringe from which the solution for dissolution was dispensed are connected via a connector (see Patent Document 1). Next, in this connected state, the solution for dissolving is injected into the vial container from the syringe. Then, the drug is uniformly dissolved in the dissolving liquid by performing a pumping operation, shaking the vial container, or the like. Next, the solution for dissolution in which the drug is dissolved (hereinafter referre...
