Disclosed herein are embodiments of a connector system for releasably connecting together tubes, for example medical tubing, and methods of making and using such a connector system, whereby the connector system includes a female coupler having a first passageway, a male coupler having a second passageway, a catch movably coupled to the female coupler, and a catch-receiving element coupled to the male coupler. The connector system further includes a release element movably coupled to the female coupler, whereby travel of the release element along or over a female coupler outer surface of the female coupler disengages the catch from the catch-receiving element to achieve a disconnected condition of the connector system. Further disclosed herein are embodiments of a connector system for releasably connecting together tubes, whereby the connector system includes at least one valve biased by a valve-biasing member disposed external to or outside of the fluid flow path.

A puncture resistant bag has an open end into which is inserted the injection port of a Peripherally Inserted Central Catheter (PICC) assembly which has a flexible catheter. The open end of the bag is irreversibly sealed by one or two fastening mechanisms each having two parts which join to seal together a first side and a second side of the bag. Each fastening mechanism has a first part joined to or passing through the first side which is captured or adhesively bonded to a second part joined to or passing through the second side. The bag has indicia indicating where to cut to remove the locking mechanisms to access the port. The bag is sized such that the port cannot be rotated to a position adjacent the open end.

A catheter control system the system can include a control unit having a first connection port. The control unit can have a first visual indicator associated with the first connection port. The system can also include a first catheter interface connector connected to the first connection port of the control unit. The first catheter interface connector can have a first visual indicator corresponding to the first visual indicator on the control unit. The first visual indicator on the first catheter interface connector can be to be active to indicate that the first catheter interface connector is connected to the first connection port on the control unit.

A respiratory mask includes a frame and a cushion module including a housing and a cushion that seals on a user's face in use. The housing includes a first connector, for example, a female connector, and the frame includes a second connector, for example, a male connector. The first and second connectors are coupled together in use. The housing includes one or more fasteners that secure the male connector to the female connector. Each fastener includes a base portion coupled to the housing and a moveable portion pivotally connected to the base portion. To assemble the mask, the male connector is inserted into the female connector such that the male connector engages the fasteners. Advancement of the male connector into the female connector causes the fasteners to change orientation from a neutral position to a toggled position and compress. The compressed fasteners apply a retention force to the male connector.

An infusion adapter for connection with an infusion fluid container includes a connection portion configured to engage an injection port of an infusion fluid container, and a port configured to connect to an intravenous line, with the port in fluid communication with the connection portion. The connection portion includes a retaining ring extending radially outward from the connection portion, with the retaining ring configured to securely connect the infusion adapter to the infusion fluid container to substantially prevent disconnection of the infusion adapter from the infusion fluid container once the infusion adapter is connected to the infusion fluid container. The retaining ring includes an indicator configured to provide visualization of insertion of the connection portion into an injection port of an infusion fluid container.

A medical device accessory comprising an interface configured to connect the medical device accessory with a medical device for administration of a medical treatment using the medical device and the medical device accessory, a plurality of electrical contacts proximate the interface, the electrical contacts comprising a lead electrical contact adapted to receive an voltage from a power source associated with the medical device and one or more identifying electrical contacts, and at least one conductor providing an electrical connection between the lead electrical contact and the one or more identifying electrical contacts. An arrangement of the one or more identifying electrical contacts connected to the lead electrical contact identifies a characteristic of the medical device accessory.

A injection site information cap includes a housing, a cover portion, an engagement portion configured to couple to and cover an injection port of an injection site, and at least one information element on the cover portion that is positioned to be automatically sensed by at least one sensor of the injection site when the engagement portion is coupled to or is being coupled to the medication injection port. Related apparatus, systems, and techniques are also described.

A flow controller arranged to provide controlled constriction of a hollow body conduit, including a catheter including a first end and a second end, a strap slidably arranged within the catheter, the strap including a third end and a fourth end, the third end arranged to be connected to the catheter to form a loop, and a tensioning means connected to the second end and the fourth end, wherein the tensioning means is operatively arranged to axially displace the strap relative to the catheter to increase and decrease a diameter of the loop.

In an embodiment, a connector or connector assembly for attaching a nasal cannula with a gas delivery hose includes a sensor port for a sensor probe positioned near an end of a nasal cannula, which can allow the sensor probe to be placed closer to the patient's nostrils than previous connector parts allowed. The connector can be configured to advantageously allow the nasal cannula to rotate relative to the gas delivery hose, thereby allowing a patient or healthcare provider to untangle or otherwise straighten the hose or the cannula. The connector assembly can be configured to automatically align locking protrusions on a first component with locking recesses on a second component, where insertion of the second component within the first component causes the second component to rotate relative to the first component, thereby aligning the locking protrusions with associated locking recesses.

A syringe adapter includes a housing having a first end and a second end positioned opposite the first end, with the housing defining a passageway, and a connector body having a first end and a second end positioned opposite the first end, with the connector body having a connection member configured to be secured to a mating connector. One of the housing and the connector body includes a tab and the other of the housing and the connector body defines a channel that receives the tab, with the connector body movable relative to the housing between a first position where the connector body is restricted from rotating relative to the housing in a first rotational direction and free to rotate relative to the housing in a second rotational direction, and a second position where the connector body is free to rotate in the first and second rotational directions.
