3000 ml Ethyl Vinyl Acetate (EVA) Legless Dual Chamber TPN Bags
Ethyl Vinyl Acetate (EVA) bags are constructed from a single-web, medical grade laminate of four different films, with a fluid contact surface of EVA, with two layers of low-density polyethylene (LDPE) enveloping a layer of ethyl vinyl alcohol (EVOH).
Our EVA single-use bags are designed for bio-pharmaceutical, laboratory and diagnostic applications. They are made from high quality, Class VI and NAO film that present extremely low extractables and have a complete testing package, validation protocol and NAO status.EVA Dual Chamber TPN Container - Legless
- This product is not made with natural rubber latex or DEHP.
- EVA container.

What is TPN?
TPN stands for Total Parenteral Nutrition. What does that mean? Healthy individuals get their nutrition via the digestive tract, or the "enteral" route. Thus, "parenteral" means that a route other than the digestive tract is used to obtain nutrition. TPN is ordered for patients who, for whatever reason, cannot obtain adequate nutrition through their digestive tract. This could be because of a blockage or a leak in the digestive tract. Some patients have absorption issues as well, perhaps due to short bowel syndrome. In short, when the digestive tract is not functional, TPN is necessary for patients to maintain adequate nutrition.
TPN is administered into a vein, generally through a PICC (peripherally inserted central catheter) line, but can also be administered through a central line or port-a-cath. Patients may be on TPN for many weeks or months until their issues resolve. Throughout the course of therapy, patients may or may not be able to ingest anything orally; whatever the case, they will not get any substantive nutrition via the oral route.
What is Ethylene-vinyl acetate?
Ethylene-vinyl acetate (EVA), also known as poly (ethylene-vinyl acetate) (PEVA), is the copolymer of ethylene and vinyl acetate. The weight percent vinyl acetate usually varies from 10 to 40%, with the remainder being ethylene. There are three different types of EVA copolymer, which differ in the vinyl acetate (VA) content and the way the materials are used. The EVA copolymer which is based on a high proportion of VA (greater than 40%) is referred to as ethylene-vinyl acetate rubber.
EVA is an elastomeric polymer that produces materials which are "rubber-like" in softness and flexibility. The material has good clarity and gloss, low-temperature toughness, stress-crack resistance, hot-melt adhesive waterproof properties, and resistance to UV radiation. EVA has a distinctive vinegar-like odor and is competitive with rubber and vinyl products in many electrical applications.
