Anyone who is in the business of administering fluids via IV sets understands the importance of a quality IV set filter. That’s why Heath Line offers quality filters composed of is polyethersulfone (PES). The sizes of the membrane pore are 0.22 μm and 1.2 μm selectable and the size remains consistent during infusion. The multiple layer, three-dimensional filter, significantly increases the capability of entrapping microparticles and reduces drug absorption rate; and there is no membrane shedding. This helps prevent phlebitis, vascular discoloration or hardening, local embolisms, scleroma, limb numbness, granuloma, etc. thus ensuring a safe, clinical infusion.
Comparing Filter Materials
Ordinary Filter Membrane (Fiber Membrane)
Hydrophilic group shed during infusion is highly toxic; shed fiber forms new insoluble particles; pore size is increased after infusion that reduces filtering rate.
General Filter Membrane (Nuclear Pore Membrane)
Repeated holes may enable the passing of large particles. Surface filtration mechanism causes severe flow rate delay.
Health Line Filter Membrane (Polyethersulfone Membrane)
Multiple layer filtering, no self-contamination.
American Infusion Nurses Society (INS) indicated that non-lipid solutions need to use a precision filter with filtering pore size 0.2μm, while lipid solutions and full parenteral nutrition mixtures need to use a precision filter with filtering pore size 1.2μm(1). 2. “Intravenous Infusion Treatment Nursing” indicated that with filters of pore size 0.2 μm articles and bacteria and other microorganisms can be filtered so that endotoxin and heat source reaction are reduced(2). 3. Scholarly researchers suggest using the precision filter with filter pore size 0.2μm for non-lipid solutions and filter size 1.2μm for lipid solutions and full parenteral nutrition mixtures (3,4,5).
