A needle free connector for fluid passage having a valve body with a first port; a second port; a hollow resilient membrane disposed in the valve body and having: a first end and a second end is disclosed. A flank is provided and extends between the first end and the second end fitting with the internal surface of the valve body. A slit of the first end is closed when the first end is disposed in the first port or opened when the first end is pushed into the valve body. The disclosure also proposes a drug recipient including a bottle or a bag designed to store drug and the needle free connector. The disclosure offers a needle free connector with a slitted resilient membrane having reduced priming volume.

Needle free connector with a collapsible resilient membrane fitting and corresponding method

Apparatus enables one or more needleless injection ports to be established on IV tubing as needed. An IV tubing-engaging portion secures the apparatus about the tubing. A puncturing member establishes fluid communication between the IV line and a sealing member on the apparatus. Connecting a syringe to the sealing member establishes fluid communication between the IV line and the syringe, enabling an injection to be made. When the syringe is withdrawn, the sealing member reseals to prevent fluid leakage from the IV line.

Apparatus for selectively establishing a needleless injection port on IV tubing, and associated methods

The various embodiments include a tubular member having an outlet. A sealing member provides a selective seal over the outlet. When the male connector is connected to a female connector, the tubular member establishes fluid communication between the connectors. In certain embodiments, fluid communication between the connectors may be interrupted even while the connectors are still connected. When the male connector is disconnected from the female connector, the sealing member reestablishes a seal over the outlet.
