Male connector and transfusion line connection apparatus equipped with male connector

摘要

The male connector of the present disclosure allows for the flow of fluids therethrough and includes a movable blunt needle having a shoulder projecting radially outwards from the movable blunt needle. The male connector also includes an outer cylinder body formed around the movable blunt needle and disposed in coaxial alignment to the movable blunt needle, a blunt needle retainer which retains the movable blunt needle so that the movable blunt needle can move in an axial direction, and a valve which opens as a result of the movable blunt needle moving in the axial direction when the posterior end presses against the valve. This occurs when the movable blunt needle is inserted into a corresponding connection site, such as a female connector, and the shoulder presses against the connection site to force the movable blunt needle in the axial direction.

主权项

1. A male connector for a transfusion line comprising:
an outer body defining a hole therethrough for the reception of fluids; a link section attached to the outer body and extending proximally from the outer body; a junction defining a fluid passageway therethrough for the reception of fluids; an elongate member at least partially disposed within the hole and axially movable relative to the hole, the elongate member defining a lumen therethrough for the reception of fluids, the elongate member including a needle section, a first end of the needle section having a first diameter and a second end of the needle section having a second diameter larger than the first diameter, the needle section being configured to penetrate a seal of a corresponding connector; and a sealing member disposed between the elongate member and the fluid passageway of the junction, the sealing member being biased towards a closed state and transitionable between the closed state and an open state upon movement of the elongate member relative to the hole of the outer body, at least a portion of the needle section of the elongate member extending axially beyond the outer body when the sealing member is in the closed state.
