PES iv filter

 

IV Sets, Let’s talk Filters

By: Health Line Marketing—June 2020

Anyone who is in the business of administering fluids via IV sets understands the importance of a quality IV set filter. We understand that at Health Line and offer 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.

Hydrophilic group shed during infusion is highly toxic; shed fiber forms
new insoluble particles; pore size is increased
after infusion that
reduces filtering rate.

Repeated holes may enable the passing of large particles. 
Surface filtration mechanism causes
severe flow rate delay.

Multiple layer
filtering,
no self-contamination.




  1. 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).
