Male connector and transfusion line connection apparatus equipped with male connector

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, a portion of the elongate member includes a movement regulating component which extends radially outward from the elongate member and is adapted to limit axial movement of the elongate member relative to the hole of the outer body;
• 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, the movement regulating component pressing against an outer surface of the hole when the sealing member is in the open state.

A transfusion line set comprising:

• a female connector comprising:
• a housing including an opening extending therethrough and at least one projection extending from an outer surface of the housing;
• and
• a seal disposed within the housing at a proximal end of the housing;
• and
• a male connector 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 such that the needle section is configured to penetrate the seal of the female 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.
