An adapter for connecting a first connector to a second connector can include a proximal portion configured to linearly engage the first connector with a snap-fit engagement. The adapter can include a distal portion configured to rotationally engage the second connector. Rotation of the adapter relative to the second connector can advance a male luer of the first connector into substantially sealing engagement with a female luer on the second connector. The adapter can be configured to displace a collar on the first connector when coupled to the first connector. The second connector can include a proximal portion that is configured to engage the first connector, such as with a snap-fit engagement.

A valve assembly including a housing having a base and an outer shell, which forms a proximal cavity and a distal cavity joined by a canal; an inner housing configured for longitudinal movement within the distal cavity; a seal positioned within the distal cavity that together with the longitudinal movement of the inner housing regulates the flow of fluid through the valve assembly; and one or more selected from the group consisting of the base notched with one or more notches and the inner housing having one or more through slots aligned to permit access to the one or more notches, the seal being a reversibly deformable sealing pin, and a torque limiter mechanism configured to resist the longitudinal movement of the inner housing distally until a sufficient radial force is applied.

A medical connector of the present invention is characterized in that: when a male connector portion is inserted into a female connector portion, a first locking portion is engaged with the female connector portion to achieve a first locked state as well as a second locked state; when the second locked state is released by operation of a second unlock operating portion and the female connector portion is moved in a disengagement direction with respect to the male connector portion, the locking member is moved in the disengagement direction together with the female connector portion while keeping the first locked state; and when the female connector portion is rotated with respect to the male connector portion, the first locked state is released.

An adapter for making a fluid connection between first and second medical fluid flow components, where the first component includes a first male or female Luer connector of a first configuration, and the component includes a second male female Luer connector of a second configuration, that is not compatible with the first configuration, includes a fluid flow conduit with a first adapter connector at a first end of the conduit and a second adapter connector at a second end of the conduit. The conduit includes a fluid flow lumen extending between the first and second ends. The first adapter connector is a male or female Luer having a first configuration that is compatible with the first medical fluid flow component connector. The second adapter connector is a male or female Luer having a second configuration that is compatible with the second medical fluid flow component connector.

Connectors are disclosed that include an outer connector, inner connector, and a clutch that can collectively limit a torque transmitted through the connector. The outer connector includes a profile disposed on an inner surface of the outer connector, and the inner connector may be disposed within the outer connector and can include an upper threaded portion and a lower threaded portion. The clutch can be disposed around and rotationally coupled to the inner connector and can include a plurality of clutch teeth extending from an outer surface of the clutch, wherein the plurality of clutch teeth are outwardly biased to be releasably engaged with the profile of the outer connector. The plurality of clutch teeth can be configured to transfer torque from the outer connector to the inner connector when the torque is below a torque limit, and prevent transfer of torque when the torque exceeds the torque limit.

A cleaning device is configured to access and remove fluid from and dry a moat region defined by a hub of a medical connector, thereby minimizing the potential for bacterial growth in the hub. The cleaning device takes the form of an absorbent block which can be inserted into the moat by extending about a central male fitting and into a gap between the male fitting and the inner wall of a female hub of the medical connector. In a preferred embodiment of the invention, the block takes the form of a tubular cylinder particularly configured for use on ENFit medical connectors wherein the absorptive feature of the cleaning device can be employed alone or in combination with another cleaning tool used to first remove any existing dried and caked solution in the hub before removing residual cleaning fluid from the moat.

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 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 distal portion of the elastomeric seal is seated radially within a region surrounded by a plurality of longitudinally extending protrusions.

A medical device, comprising a hub or housing having a push tab including a main portion extending radially from an upper surface of the hub or housing, and at least one anti-rotation feature for resisting rotation of the hub or housing. A cannula is directly or indirectly connected to the hub or housing. The medical device may be a catheter, the cannula may be a catheter tube, and the hub or housing may be a catheter hub or an introducer needle tip shield for the catheter.

A slip luer assembly includes a hub member and a latch member coupled to the hub member. The hub member includes an outer hub surface, and inner hub surface and a window surface. The window surface defines a window extending from the outer hub surface to the inner hub surface. The latch member includes at least one blade. The latch member is configured to be actuated between a first position and a second position. In the first position, the at least one blade is not positioned within the window of the hub member. In the second position, the at least one blade is positioned at least partially within the window of the hub member.

A safety cap for use with a needleless connector. The safety cap includes a body configured to at least partially enclose a head of the needleless connector (NC). The body is configured to achieve a first configuration that can be securely sealed to the NC and a second configuration that cannot be securely sealed to the NC. The second configuration is different from the first configuration. The safety cap also includes a detent in communication with the body which is configured to prevent the body from transitioning from the second configuration back to the first configuration.
