A bag connector system includes a first coupling element, with a self-closing seal and a housing having a fluid inlet port and a fluid outlet port, and a second coupling element, with a housing having a fluid inlet end and a fluid outlet end. The fluid inlet end is configured to displace the self-closing seal when inserted into the fluid outlet port of the first coupling element. A bag connector system optionally includes a locking mechanism to maintain the first coupling element and second coupling element in a coupled state. Uncoupling of the first and second coupling elements results in minimal fluid contamination on the outer surfaces of the coupling elements. The bag connector systems provided herein are included in medical appliances for waste management.

Self-closing bag connector

Drug delivery devices having integrated non-luer connectors are described. An exemplary drug delivery device includes a container with a non-luer connector that prevents connection of a standard female luer connector to the container. One or more embodiments pertain to a container with a non-luer connector that prevents the formation of a fluid-tight seal between a standard female luer connector and the container. A non-luer connector for attachment to a container having a non-luer element is also described.

Non-luer connectors

The body has a fluid inlet port for receiving pressurized fluid and a fluid outlet port connected to the retention balloon. A first passage connects the fluid inlet port and the fluid outlet port, A second passage in the body is connected to the balloon fluid return path and is at the pressure of the retention balloon. A valve prevents fluid flow through the first passage when actuated. The valve includes a pressure-responsive member movable to a position to obstruct fluid flow in response to fluid pressure in the second passage exceeding the predetermined level. Flexible means such as a membrane defines a normally open portion of the first fluid passage, which is closed by the moveable means bearing on the membrane when pressure exceeding the predetermined level actuates the valve.

Apparatus for preventing over inflation of the retention balloon in medical catheters and airway devices

The present invention relates to a valve system for an inflatable portion of an indwelling medical device and more particularly to a valve system for fluid regulation of a catheter comprising a fluid inflatable portion that undergoes pressure changes within the body during use.

Drug delivery connectors are provided for permitting and blocking fluid flow between a container and a catheter connector or other drug delivery site. Embodiments of the drug delivery connectors include a ball valve for forming a releasable seal within the drug delivery connectors. In one or more embodiments, the ball valve prevents fluid flow between an open proximal end and an open distal end of the drug delivery connector and is movable in a proximal direction to release the releasable seal to permit fluid flow from the open proximal direction to the open distal direction. Methods of delivering medication to a catheter connector that includes an actuator are also provided.

The present invention relates to a valve system for an inflatable portion of an indwelling medical device and more particularly to a valve system for fluid regulation of a catheter comprising a fluid inflatable portion that undergoes pressure changes within the body during use. The present invention also relates to methods of treatment using said valve system and indwelling medical devices comprising said valve systems.

Drug delivery systems are provided that include an actuator assembly permanently attached to a filter for connection of a container containing medications such as epidural anesthesia, to a delivery site. In one or more embodiments, the actuator assembly includes a projection with an opening extending from a distal end of the actuator assembly in a proximal direction and the filter includes an inlet and an outlet in fluid communication with the opening. The filter includes a housing including two plates joined together or a cylindrical body defining a cavity containing filter materials. A conduit may be attached to the outlet of the filter to allow connection of the drug delivery systems described to a delivery site, such as a catheter. Methods of administering a medication to a delivery site are also provided.

Safety drug delivery system

Drug delivery devices having non-luer connections and adapters and adaption connectors for providing non-luer connections to drug delivery devices are provided. An exemplary drug delivery device for use with a catheter connection includes a blunt needle component with a non-luer connection and a filter component with a non-luer connection, wherein the non-luer connections of the blunt needle component and filter component are incompatible with standard luer fitting and intravenous route-accessing devices. In one or more embodiments, an adapter having a non-luer connection at one end and a luer connector is provided for use with blunt needle components and filter components wherein one of the blunt needle component and the filter component includes a luer connection and the other of the blunt needle component and the filter component includes a non-luer connection. Methods of delivering liquid medication to a catheter are also provided.
