Problems solved by technology

[0006] However, in the above-mentioned conventional connector assembly, since the syringe is held by the lock adapter with respect to the needle seat of the first connector, the syringe will not come off even if it is pulled. or locking adapter is rotated in the direction of thread loosening, the syringe simply disengages
If the syringe is detached from the hub of the first connector, there is a danger that the liquid agent will be scattered from the mouth of the syringe, etc., and the liquid agent will adhere to the medical personnel, etc., and the liquid agent cannot be transferred safely and reliably through the connector assembly. agent

Abstract

A first connector (2) comprises an external cylinder (4) forming a cylindrical shape, a first connector main unit configured with an internal cylinder forming a cylindrical shape and a hub (12) disposed at a proximal end of the external cylinder (4), a hollow needle supported by the hub (12), a first sealing member supported by the internal cylinder, a coil spring (8) as penetrating portion biasing means for biasing the first sealing member toward the tip direction, and a clamping member disposed upon the external cylinder (4). Upon the inner periphery portion of the proximal end of the external cylinder (4), a claw (44) is formed so as to protrude toward the inner side. In addition, upon the outer periphery portion of a large diameter portion (1212) of the main unit portion (121) of the hub (12), a plurality of ratchet teeth (126) which are engagable with the claw (44) of the external cylinder (4) are formed so as to protrude toward the outer side. Accordingly, rotation in only one among the positive and negative directions of the hub (12) is prevented.

Description

technical field [0001] The present invention relates to a connector and a connector assembly. Background technique [0002] Generally, anticancer agents, immunosuppressants, and other pharmaceuticals that are dangerous if accidentally touched by medical staff are stored in a powder state in a bottle container sealed with a rubber stopper at the mouth. [0003] When taking out medicine from such a vial container, the following operations are performed. [0004] First, the mouth of the bottle container and the mouth of the syringe from which the solution for dissolving has been dispensed are connected by a connector assembly composed of a first connector and a second connector. In this case, the outer peripheral portion of the mouth of the syringe is provided with a locking adapter (for example, refer to Patent Document 1) with threaded teeth formed on the inner peripheral surface, and when the syringe is connected to the hub of the first connector, the The locking adapter o...
