A medical connector can include a body having a fluid path with an inlet port, an outlet port, a luer portion, and a post extending through a fluid path. An arm having a latch member is coupled to the body to engage a ridge or thread on an exterior surface of a reciprocal connector. The arm may also include an extension. When the connector is in an open position, the latch member restricts retraction of the reciprocal connector from the outlet port. A seal is coupled to the body and includes a flap extending across the outlet port or a bellows to compress along an axis. In a closed position, the post restricts flow through the luer portion. In an open position, the post permits flow through the luer portion.

A filter housing containing a filter is fluidly coupled to an end of the passage that is exterior to the body, the filter housing terminating in a vent that is fluidly coupled to the passage. A first fluid path is formed through the cannula, the passage and the vent, and a second fluid path is formed through the female connector, the body, and the male connector, wherein a closed system is provided when the male connector is uncoupled from the medical device.

Syringe adapter

A needleless connector includes a body having a fluid path, a vent path, and a male fitting. The needleless connector also includes a valve disposed within the male fitting. The valve is configured to move between a first configuration, in which the fluid path is blocked, and a second configuration, in which the fluid path is open. The needleless connector further includes a seal disposed around the valve. The seal is configured to separate the fluid path from the vent path in the first configuration and the second configuration. Moving the valve from the first configuration to the second configuration also opens the vent path. The seal maintains the separation between the fluid path and the vent path when the valve moves from the first configuration to the second configuration.

Male luer with fluid path and vent path seals

A multi-port connector such as a closed intravenous (IV) access device with a y-port needle-free connector may be provided. The multi-port connector may include a main housing with a longitudinal axis, a needle free connector disposed along the longitudinal axis, and a y-port extending from a sidewall of the main housing at an angle that is non-parallel with the longitudinal axis. The needle-free connector may include a compressible sealing member that, when compressed opens a first fluid pathway from a first port, through a chamber within the housing, and to an output port. The y-port may be fluidly coupled to the chamber and the output port.

Closed IV access device with y-port needle-free connector

A collapsible valve comprising a first portion with at least one dimple in a side thereof, and a second portion, the second portion being narrower than the first portion and arranged along an axial dimension of the first portion, the second portion including a cut therein.

Collapsible valve

A syringe includes a syringe body, a first plunger, a second plunger, and an inner tube. The syringe body defines a syringe cavity and a syringe port, wherein the syringe port is in fluid communication with the syringe cavity. The first plunger is disposed within the syringe cavity and defines a first chamber in the syringe cavity, wherein the first chamber is in fluid communication with the syringe port. The second plunger is disposed within the syringe cavity, the first plunger and the second plunger cooperatively defining a second chamber in the syringe cavity. The inner tube comprises an inner tube lumen, wherein the inner tube and a first plunger shaft lumen of a first plunger shaft define an annulus therebetween, the annulus in fluid communication with a first plunger channel of the first plunger and the annulus permits fluid communication between the syringe port and the first plunger channel.

Multi-chamber syringe

Syringes are described herein. A syringe includes a syringe body, a first plunger, a biasing member, and a retention member. The syringe body defines a syringe cavity and a syringe port, wherein the syringe port is in fluid communication with the syringe cavity. The first plunger comprises a first plunger shaft extending from the first plunger, the first plunger disposed within the syringe cavity and defining a first chamber in the syringe cavity, wherein the first chamber is in fluid communication with the syringe port. The biasing member is coupled to the first plunger shaft, wherein the biasing member urges the first plunger to advance toward the syringe port. The retention mechanism prevents the biasing member from advancing the first plunger in an engaged position and permits the biasing member to advance the first plunger in a released position.

Syringe with priming mechanism

Needleless connectors are described herein. A needleless connector includes a housing comprising a cavity and a proximal fluid port in fluid communication with the cavity. The connector further includes a filter support disposed at least partially within the cavity. The filter support can include a distal fluid port in fluid communication with the proximal fluid port. The connector further includes a filter disposed circumferentially around the filter support and between the proximal fluid port and the distal fluid port.

Needleless connector with in-line filter

A pumping system comprising a pump comprising a door for access within a housing of the pump, a pump segment configured for conveying a fluid based on compression of the pump segment, a pump segment frame for preventing said pump segment from stretching, a visual placement indicator configured for facilitating in a proper placement of the pump segment frame in the housing, and a non-pinching valve configured to be disposed in the housing and to control a flow of the fluid without requiring pinching of a tube.

Fluid flow control by a non-pinching valve

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.
