Abstract

Disclosed is a connector assembly provided with a first connector having a tubular first connector body, a hollow needle supported inside the first connector body and a first sealing component that can be pierced by the hollow needle, and a second connector having a tubular second connector body and a second sealing component. The second sealing component is disposed in the second connector body, is attached to a first piercing section when inserted into the first connector body, and, in that state, is pierced by the hollow needle together with the first piercing section. The connector assembly is further provided with an operation restricting means which, when the second connector is inserted into the first connector, temporarily interrupts and restricts the insertion operation, but allows resumption of the insertion operation when the restriction is removed, and which, when the second connector is withdrawn from the first connector, temporarily interrupts and restricts the withdrawing operation, but allows resumption of the withdrawing operation when the restriction is removed.

Description

technical field [0001] The present invention relates to connector assemblies. Background technique [0002] Usually, anticancer agents, immunosuppressants, and other pharmaceuticals that are dangerous if medical workers accidentally touch them are contained in a powder state in a medicine bottle container with a mouth 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 referred to as "l...
