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.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Patent Application No. 16 / 266,877, filed February 4, 2019. Background technique [0003] Infusion sets are constructed by joining multiple translucent polymer tubing segments to multiple translucent or opaque polymer components. The bond is typically formed by applying a thin layer of solvent or adhesive to one or both contacting surfaces and then bringing the two surfaces together. The contact surface of the tubing may be at the inner diameter, outer diameter, or both, up to a certain length from one end. The solvent / adhesive can be applied internally, externally, or both. The bonded area, or bonded length for a given diameter, is a critical parameter which, if not controlled, can lead to leakage or easy separation of the infusion set. Bonding parameters may vary significantly due to design imperfections, assembly process imperfections and process variations. [0004] Chec...
