Classification
Classification by Function
Standard Infusion Set: Suitable for the infusion of most routine medications; this is the most common type.
Precision Filtration Infusion Set: Uses a nuclear pore membrane or polyethersulfone membrane, etc., with filter pore sizes of 5 microns, 3 microns, and other specifications. It effectively filters particles, reduces local irritation, and prevents phlebitis.
Light-Shielding Infusion Set: Made of medical light-shielding materials, it prevents certain clinical drugs from undergoing physical or chemical reactions due to light exposure during infusion, thus preventing changes in drug composition.
Air Purification Infusion Set: An air filter is installed at the air intake to filter out bacteria, dust, and other impurities in the air, ensuring that the air entering the infusion bottle is clean.
Classification by Infusion Method
Burette Infusion Set: Suitable for pediatric infusions and situations requiring precise monitoring of infusion dosage.
Bag Infusion Set: Used with bag-type infusion containers; it is lightweight and less prone to breakage.
Bottle Infusion Set: Used with traditional glass infusion bottles; it is widely used.
