Intrapur Lipid IV Filter 1.2 Micron Inline Filter

Product Overview

The Intrapur Lipid 1.2 µm IV Filter from B. Braun is a sterile, single-use inline filtration device specifically developed for lipid-containing parenteral solutions. The filter utilises a positively charged polyamide membrane with a nominal pore rating of 1.2 µm, which is the recommended filtration threshold for lipid emulsions per infusion therapy guidelines. Its large effective filtration area of 10 cm² ensures high flow rates while maintaining reliable particle retention throughout the infusion cycle.

A dual-membrane design separates liquid filtration from air elimination. The hydrophilic polyamide layer retains particles, precipitates, and fungi larger than 1.2 µm; blockage of this membrane can serve as an early indicator of physicochemical incompatibility in the admixture. The hydrophobic venting membrane passively eliminates air bubbles, reducing the risk of air embolism without requiring manual de-airing. The filter housing features universal Luer-Lock connectors for secure, leak-free integration into standard IV administration sets and is compatible with B. Braun Infusomat and Space infusion pump lines.

Specifications

Clinical Indications

• Inline filtration of total parenteral nutrition (TPN) admixtures containing lipid emulsions in ICU and ward settings
• Retention of particulate contaminants and precipitates arising from calcium-phosphate or drug incompatibility reactions during multi-component infusion therapy
• Air elimination during gravity and pump-driven infusion of lipid-containing solutions to reduce the risk of venous air embolism
• Filtration of lipid-based intravenous medications in neonatal and paediatric intensive care where smaller particle loads pose heightened clinical risk
• Integration into home parenteral nutrition (HPN) infusion sets for ambulatory patients requiring long-term IV nutritional support

Frequently Asked Questions

Why is a 1.2 µm filter required for lipid emulsions instead of a 0.2 µm filter?

Lipid emulsion droplets typically range from 0.25–0.5 µm in diameter. A 0.2 µm filter would block the lipid globules themselves, preventing drug delivery. The 1.2 µm pore rating, as recommended by the Infusion Nurses Society (INS) Standards of Practice and the German KRINKO/BfArM guidelines, allows lipid particles to pass while retaining larger contaminants, precipitates, and fungi.

How does the Intrapur Lipid filter indicate an incompatibility reaction?

When incompatible drugs or electrolytes form precipitates in the infusion line, these solid particles accumulate on the 1.2 µm membrane and gradually occlude the filter. The resulting increase in line pressure or decrease in flow rate serves as a visible alarm signal that a physicochemical incompatibility has occurred, prompting clinicians to investigate and intervene before the precipitate reaches the patient.

Is this filter suitable for neonatal patients?

Yes. B. Braun confirms that the Intrapur Lipid filter is approved for adult, paediatric, and neonatal patients. The low filling volume of 3.46 mL minimises dead-space volume, which is particularly important in neonatal care where total fluid volumes are small. For neonatal-specific applications, B. Braun also offers the Intrapur Neonat Lipid variant with an even lower priming volume.

How long can the filter remain in use during a single infusion?

In accordance with institutional infection control protocols and the manufacturer’s instructions for use, the Intrapur Lipid filter should be replaced at least every 72–96 hours or with each new infusion set change, whichever comes first. Facilities should follow their own IV therapy policies and relevant national guidelines such as those issued by the Singapore Ministry of Health or the INS.
