Some embodiments disclosed herein relate to medical connectors with a housing comprising a proximal body member and a base member that form an internal cavity with a proximal abutment surface. A seal member and a rigid, hollow elongated portion are located within the internal cavity such that a proximal tip of the elongated member extends proximally within the internal cavity further than the abutment surface.

A medical connector includes: a housing comprising a male connector attachment/detachment part, the housing defining a liquid flow path; and a valve that is vertically movable with respect to the housing between a closed position for closing the male connector attachment/detachment part, and an open position in which a flow path in a male connector communicates with the liquid flow path, by the valve being pressed down from the closed position by the male connector against a biasing force. The valve comprises a head portion that closes the male connector attachment/detachment part when the valve is at the closed position, and a body portion that is connected to a bottom end of the head portion and receives the biasing force. A Young's modulus of the body portion is larger than a Young's modulus of the head portion.

A ported catheter adapter and septum actuator having various features to prevent displacement and dislodging of the septum actuator when accessing the patient's vasculature via the inserted infusion device. In particular, the systems and methods of the present invention provide an intravenous infusion device incorporating a septum actuator with a retention tab that interacts with a retention ring that is incorporated into the valve of a side port. This interaction retains the septum actuator within the lumen of the catheter adapter, thereby allowing for subsequent access to the patient's vasculature.

A soft grip medical connector comprises a housing with an upstream end, a downstream end and a lumen extending through a central portion thereof. A flexible member comprises a valve portion integrally formed with a sleeve portion. The valve portion is positioned within a section of the housing and is configured to control a flow of fluid through the housing lumen. The sleeve is inverted to envelope at least a portion of the outer surface of the housing. In some embodiments the gripping portion is integrally formed with the valve portion. In some embodiments, the connector is also generally configured to create a positive pressure in a catheter lumen upon removal of a syringe or other medical device from the upstream end of the connector. Methods of making a medical fluid connector generally comprise forming a valve member with a sleeve extending there from, and assembling the valve, sleeve and housing.

Described is a priming device to prime a gas from a fluid delivery system by receiving the gas and a fluid used to push the gas into a chamber, the priming device including a housing having a chamber, an inlet port, and an opening to release gas received into the chamber. The device further includes a valve extending from the inlet port toward the chamber and a cover body comprising one or more flexible protrusions extending axially inward from an inner surface of the cover body. The cover body has an open first end, an open second end, and an axis between the first end and the second end, the first end configured to couple with a male luer connector, the second end configured to couple with the inlet port of the housing, wherein the cover body is moveable relative to the housing.

A catheter system may include a needleless connector, which may include a distal end, a proximal end, and a valve disposed between the distal end of the needleless connector and the proximal end of the needleless connector. The catheter system may include a vent assembly, which may include a proximal component and a distal component. The proximal component may include a male luer adapter, which may include a male luer. The distal component may include a distal end coupled to the proximal end of the needleless connector, and a proximal end coupled to the male luer adapter. In response to movement of the proximal component from a proximal position to a distal position with respect to the distal component, the male luer of the male luer adapter may open the valve to vent air inside the catheter system.

Some embodiments disclosed herein relate to medical connectors with a housing comprising a proximal body member and a base member that form an internal cavity with a proximal abutment surface. An elastomeric seal with a collar and without a guide member is positioned within the internal cavity. A rigid, hollow elongated portion is located within the internal cavity such that in an open configuration, a tip of the elongated portion is more proximal than a proximal surface of the elastomeric seal.

A ported catheter adapter having a combined blood control valve and port valve, wherein the combined valve comprises one or more vents that permit the passage of air and prevent the passage of fluids. The one or more vents are located on the outer surface of the valve so as to avoid being overlapped with the pathway of the side port. As such, fluid communication between the side port and the vents is prevented. Various venting configurations are provided. The invention further includes a valve actuator that is advanced through a slit in the membrane of the valve to provide a pathway for fluid to bypass the valve.

A medical connector is described which is formed by a body having an inlet port, an outlet port through a male luer portion of the body, and a fluid path between the inlet port and the at least one outlet ports. A retractable post extends through the fluid path in the male luer sealing a tip of the male luer thereby closing the fluid path when the connector in not activated. There is a seal between the retractable post and the body that forms a fluid volume within a portion of the cavity. The fluid path passes through the fluid volume. When actuated, the retractable post is forced away from the tip of the male luer, thereby opening the fluid path through the medical connector and decreasing the fluid volume.
