What's that flat circular thing on the IV tube?

Every time you receive an IV infusion, have you ever noticed that unassuming little disc on the IV tubing?

It hangs quietly in the middle of the line, seemingly ordinary, yet it's a crucial tool safeguarding our infusion safety.

Ensuring the safety of people's lives and property—this isn't just an ordinary plastic part,but a precision medication filter!

During medical infusion procedures, seemingly clear solutions may harbor invisible risks. Glass shards, rubber particles, drug crystals, microorganisms... these potential threats can all enter the body through intravenous administration. The core material within that “small disc” serves as the final line of defense designed to intercept these hidden dangers.

Why is this tiny filter so important?

At this point, we must mention the ePTFE filter membrane developed by UNM. This membrane features a unique microporous design, with billions of precisely controlled micropores per square centimeter. The size of these pores is meticulously calculated to ensure smooth passage of the solution while effectively intercepting all particles and bacteria larger than 0.22 microns. Like an exquisitely fine mesh, it permits only safe pharmaceutical components to pass through while keeping all potential hazards firmly at bay.

It's more than just filtering!

Some may worry: Could such a fine filter mesh affect infusion speed? This is precisely where the ingenuity of the ePTFE filter membrane lies. Its three-dimensional mesh structure maintains a high porosity of 80%-95% while ensuring filtration precision, guaranteeing smooth flow of the medication solution. More importantly, this material exhibits extremely low drug adsorption properties, preventing the “theft” of active ingredients from the solution. This guarantees patients receive the full therapeutic dose.

As a professional membrane material R&D enterprise, UNM understands that medical products must be flawless. We have established stringent quality standards for ePTFE filter membranes: every batch undergoes biocompatibility testing to ensure absolute safety for the human body; each filter membrane undergoes integrity testing to guarantee reliable and stable filtration performance. Within this small “disc” lies UNM's reverence for life and unwavering commitment to quality.
