Needleless connectors: a primer on terminology.

Area of Science:

• Medical Devices
• Intravenous Therapy
• Healthcare Technology

Background:

• The last two decades have seen a significant rise in needleless connectors for intravenous (IV) access.
• These devices connect multiple IV sets and catheter hubs, aiming to reduce needlestick injuries.
• Current market diversity in design and function leads to professional confusion.

Purpose of the Study:

• To provide a comprehensive overview of various needleless connector technological designs.
• To clarify the distinct characteristics and functionalities of different device types.
• To recommend standardized, concise definitions for universal professional acceptance.

Main Methods:

• Literature review of existing needleless connector devices.
• Analysis of technological designs, internal mechanisms, and external features.
• Comparative assessment of device functionalities and applications.

Main Results:

• Categorization of needleless connectors based on design principles (e.g., mechanical, fluid-filled).
• Identification of key differentiating characteristics, including sealing mechanisms and material composition.
• Highlighting of functional variations impacting flow rates, compatibility, and infection risk.

Conclusions:

• Standardized terminology and clear definitions are crucial for reducing confusion in healthcare settings.
• Understanding device types and characteristics enhances safe and effective intravenous therapy.
• Adoption of recommended definitions will improve communication and practice among healthcare professionals.
