A safety medical connector includes a composite inner pipe, a first resilient element, a sealing element, and a housing. The first resilient element hermetically seals the entrance of the housing, and the sealing element hermetically seals the exit of the housing; hence, thanks to the double hermetic seal structures, the safety medical connector is leakproof and airtight. When in use, part of the composite inner pipe is secured and stationary, thereby enhancing structural stability.

A safety medical connector includes a composite inner pipe, a first resilient element, and a second resilient element. The first resilient element hermetically seals the entrance of the composite inner pipe. In operation, the first resilient element is pushed aside such that the entrance of the inner pipe opens. After use, the second resilient element drives the composite inner pipe and the first resilient element to restore position. Hence, the safety medical connector advantageously features reduced liquid residue and enhanced structural stability.

A luer access device (LAD) and a method of attaching the same are provided to create a sterile fluid-flow path. The LAD includes a female luer connector that has an internal female split septum disposed at a proximal end thereof and is coupled to an internal surface of the LAD. A male luer connector is coupled to an external surface of the female split septum. Additionally, a male split septum is disposed within a male luer tip and seals an opening of a distal end of the male luer connector. At least one aperture is disposed through a sidewall of the distal end of the male luer connector. An internal cannula is exposed out of the female luer connector to open the female split septum upon engagement with the male luer connector.

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 medical connector includes a housing with a central axis, a hollow bore, and a narrowed passage. The connector further includes a rigid valve member configured to move along the axis of the connector as the connector moves between an open and closed configuration. The connector includes a resilient member coupled to the valve member and the housing.

Positive displacement using a connector with dual diaphragms is provided. For example, the connector includes a single fluid flow path, an air chamber and a valve. The single fluid flow path is configured for delivering fluid to a person and configured for receiving fluid from a person. The air chamber configured for expelling air from the air chamber when an actuator is inserted into the connector and for receiving air into the chamber when the actuator is removed from the connector. The valve plug comprises two diaphragms that separate the air chamber from the single fluid flow path. The valve plug is configured for creating positive displacement by returning the valve plug to its uncompressed state when the actuator is removed from the connector.

A fluid-connecting element with a first receiving space with a first connecting element and a first displaceable valve element, and a second receiving space with a second connecting element and a second displaceable valve element. A fluid connection between the first receiving space and the first connecting element being interrupted by the first valve element in the first position, and a fluid connection between the first receiving space and the first connecting element being opened by the first valve element in the second position. The second valve element is displaceable between two positions, wherein a fluid connection between the second receiving space and the second connecting element is interrupted by the second valve element in the first position, and a fluid connection between the second receiving space and the second connecting element is opened by the second valve element in the second position.

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 fluid connection system and a method of attaching the same are provided to create a sterile fluid-flow path. The connection system includes a fluid access device having a female connector with a female elastomeric member disposed at a proximal end thereof and is coupled to an internal surface of the fluid access device. A male connector is coupled to an external surface of the female elastomeric member. Additionally, a male elastomeric member is disposed within the distal end of the male connector and seals a distal opening thereof. At least one aperture is disposed through a sidewall of the distal end of the male connector. An internal cannula is exposed out of the female connector to open the female elastomeric member upon engagement with the male connector. The male connector is sealed to the female connector by the male elastomeric member.
