AI Technical Summary

Technical Problem

Existing infusion systems require additional equipment and user training to prevent air bubbles, which can lead to air embolism and increase complexity and cost.

Method used

Infusion components and IV tubing with hydrophilic coatings or substrates that reduce the wetting angle, allowing air bubbles to quickly slide away or pop, thereby reducing priming time and the risk of air embolism.

Benefits of technology

Hydrophilic surfaces minimize the need for additional equipment and training, shorten priming time, and reduce the risk of air embolism, improving user safety and manufacturing efficiency.

Abstract

Hydrophilic infusion tubing and infusion components are provided. The fluid passageway connects a first fluid port and a second fluid port and is formed by a substrate suitable for fluid infusion and a hydrophilic fluid contact surface disposed on an inner surface of the fluid passageway. The hydrophilic fluid contact surface provides a water wetting contact angle that is less than the water wetting contact angle provided by the substrate. An infusion set is also provided.
