Abstract:
A non-PVC, non-DEHP material is provided for medical grade tubing (14). The material comprises a blend of polyurethane and polyester. The resultant tubing of the present invention has good low temperature characteristics, is autoclavable, and RF sealable. Accordingly, the resultant tubing (14) can be utilized for applications which heretofore have been filled in the marketplace by DEHP plasticized PVC tubing. In an embodiment, the material includes a citrate ester.
Abstract:
The present invention provides a non-PVC, non-DEHP material that can be used for medical grade tubing. Additionally, the present invention provides medical grade tubing made from such a material. To this end, the present invention provides a medical grade tubing (14 and 20), comprising a multilayer coextruded structure including: a layer comprising a blend of polyurethane and polyester; and a layer comprising a blend chosen from the group consiting of: polypropylene, ethylenevinyl acetate, and polyurethane; polypropylene and styrene-ethylene-butylene-styrene; polypropylene, styrene-ethylene-butylene-styrene, and ethylenevinyl acetate; polypropylene, ethylenevinyl acetate, styrene-ethylene-butylene-styrene, and thermoplastic polyester elastomer; polypropylene, ethylenevinyl acetate, styrene-ethylene-butylene-styrene, thermoplastic polyester elastomer, and polyurethane; polyester, thermoplastic polyester elastomer, and polyurethane; polyester and polyurethane; and polypropylene, styrene-ethylene-butylene-styrene, and polyurethane.
Abstract:
A non-PVC, non-DEHP material is provided for medical grade products such as tubing and containers. The material comprises a monolayer blend of a polyurethane based material. In an embodiment, the resultant product of the present invention has good low temperature characteristics, is autoclavable, and RF sealable. Accordingly, the resultant product can be utilized for applications which heretofore have been filled in the marketplace by DEHP plasticized PVC products.
Abstract:
A steam sterilizable unit (10) for inactivating pathogens in a body fluid is provided comprising a plastic structure for housing a therapeutically effective amount of a methylene blue solution. The plastic structure preferably includes at least an inner layer (128) constructed from a non-PVC plastic. Preferably, the methylene blue solution has a pH of less than 7.0 and preferably less than or equal to approximately 6.3.
Abstract:
A plastic composition is disclosed which has particular application in the manufacture of blood bags (40) and other medical products. The composition has anti-hemolytic effects when used in the storage of red blood cells. In connection with one aspect of the present invention, the plastic composition comprises the combination of a non-PVC plastic and a selected quantity citrate ester sufficient to suppress hemolysis of red blood cells. The non-PVC material is preferably a polyolefin copolymer. Materials other than citrate ester may also be used with polyolefin as a hemolysis suppressant.

Abstract:
L'invention se rapporte à un matériau non PVC et non DEHP pour produits d'usage médical tels que des tubes et des récipients. Ce matériau comprend un mélange monocouche d'un matériau à base de polyuréthane. Dans un mode de réalisation particulier, le produit obtenu dans la présente invention présente de bonnes caractéristiques à basse température, il peut être soumis à autoclave et il est scellable par HF. Ainsi, ce produit peut être utilisé dans des applications qui jusqu'à présent ont été satisfaites dans le commerce par des produits en PVC plastifiés par DEHP.
Abstract:
Composition plastique utilisable tout particulièrement dans la fabrication de sacs pour conserver le sang (40) et autres produits médicaux. Ladite composition a des effets anti-hémolytiques lorsqu'utilisée pour conserver des globules rouges. Selon l'un des modes de réalisation de la présente invention, la composition plastique se compose d'une combinaison d'un plastique qui n'est pas du chlorure de polyvinyle (CPV) et d'une quantité d'ester de citrate suffisante pour empêcher l'hémolyse des globules rouges. Le matériau plastique non CPV est de préférence un copolymère de polyoléfine. On peut également utiliser des matériaux autres que l'ester de citrate avec la polyoléfine comme agent anti-hémolyse.
