Precision filtering, ensure safety

2024-07-24

Intravenous infusion is a common medical procedure that involves delivering liquids, medications, electrolytes, or nutrients directly into the patient's bloodstream through a vein. Ordinary filtration infusion sets and precision filtration infusion sets, as devices for intravenous infusion, differ in their filtering capabilities and application scenarios. The increasing clinical demand for infusion safety has led to a growing emphasis on precision filtration infusion sets due to their high filtration accuracy.

Potential hazards of ordinary infusion sets during the infusion process

Ordinary infusion sets can pose hazards such as infusion reactions during the infusion process, primarily caused by insoluble particles.These particles may originate from sources like plastic particles, rubber particles, fibers, lint, dust particles, carbon black particles, insoluble gel particles, crystalline particles, glass fragments, and drug particles. Once these particles enter the human body, they can lead to clinical issues including allergic reactions, phlebitis, vascular embolism, microcirculation blockage, arteriosclerosis, pyrogenic reactions, granulomas, and pulmonary embolism.

The role of precision Filters

To address these potential hazards, precision filters used to filter particles with diameters of 5 micron and smaller. According to regulations issued by the National Food and Drug Administration, such infusion devices capable of filtering smaller particles are referred to as precision filtration infusion sets. When equipped on infusion sets, they can effectively reduce the impact of particles on patient health during the infusion process.

Precision filter’s target groups

Such as pediatric patients, elderly patients, cancer patients, cardiovascular patients, critically ill patients, and those who require long-term infusion therapy.

XINN’S disposable precision filter

XINNA ‘s disposable precision filters are available in various specifications to meet different clinical infusion needs. The filter features an air vent design with an embedded breathable liquid-resistant membrane, which can automatically expel air from the upper end of the filter disc, stop fluid flow automatically, prevent the drip chamber from running dry, and prevent air embolisms.

Advantages

Precision Filtration:

Utilizes a PES (Polyethersulfone) filtration membrane with pore sizes available in 0.2 micron, 1.2 micron, 2 micron, 3 micron, and 5 micron. The filtration rate is high, exceeding ≥95%, reducing the occurrence of infusion reactions and complications.

Automatic Air Venting:

The air vent design incorporates an embedded breathable liquid-resistant membrane, which can automatically expel air from the upper end of the filter disc.

Automatic Fluid Stopping:

The filtration membrane has an anti-bubble function, preventing fluid from entering the lower tubing. Automatic fluid stoppage is achieved at the end of the infusion.
