International Classification:

A61M 25/14
A61M 25/06

US Classification:

60416706, 604256

Abstract:

A septum is disclosed that can be utilized in a catheter assembly to selectively seal an opening in the catheter assembly. The septum has a tube portion and a plug portion. The plug portion has a slit extending through it. The septum can transition from a non-collapsed state to a collapsed state. When the septum is in a non-collapsed state, the plug portion is offset from the tube portion such that some of the length of the slit extends outward from the distal end of the tube portion. When the septum transitions to the collapsed state, the plug portion is moved inward into the internal cavity such that some of the length of the slit may or may not extend outward from the distal end of the tube portion.

Abstract:

Tube markers for use in infusion sets are provided. An infusion tube includes a tube marker positioned from a tube end at a distance equal to the distance between an external edge and a hard stop of a fluid port of an infusion set component. The tube marker provides an external visual indicator of the fit between the infusion tube and the infusion set component, such as whether there is a gap between the end of the infusion tube and hard stop of the fluid port. The tube marker may be pad printed or laser etched on the tube. The tube marker may also be a tube sleeve over molded or heat shrunk onto the tube. Methods of providing tube markers are also provided.

International Classification:

A61M 5/14

Abstract:

Anti-snagging components for use in infusion sets are provided. The anti-snagging component includes a sliding surface that guides an infusion set component past an obstruction when the infusion set is moved during manufacture or use. An anti-snagging structure may be integrally formed as a portion of an infusion set component or the anti-snagging structure may be a separate component that connects or attaches to an infusion set component. Some anti-snagging structures include a covering portion to cover a needleless connector and a tail portion to connect to a length of tubing. The covering portion may include an anti-microbial coating.
