Assembly of the catheter with fluid osmolality enlarger

摘要

"Assembly of the catheter with fluid expander of osmolality.The present invention relates to an assembly of the catheter, which comprises a hydrophilic catheter, a fluid umedecedor for moistening of the catheter.And a receptacle that encloses at least a part insertable catheter and the fluid umedecedor.In addition, the fluid umedecedor is a solution that incorporates at least one compound expander of osmolality, the total concentration of the compound (s) expander (s) of osmolality being very high.Preferably, exceeding 600 mOsm / DM ^ 3 ^.The fluid umedecedor may be disposed in contact with the surface layer of the hydrophilic catheter in the receptacle for the preservation of the hydrophilic surface layer in a state moistened DurantAnd accommodation in said receptacle and the provision of a catheter assembly ready for use.Or be willing to maintain the fluid umedecedor separated from the layer of hydrophilic surface of the catheter during storage.But to be brought into contact with said surface layer, hydrophilic with activation before an intended use of the catheter. A method and a fluid umedecedor similar are also described.The provision of the compound expander of osmolality in the fluid umedecedor presents several advantages, per se, such as enhancing properties of the hydrophilic coating.A moistening process more predictable and controllable production more convenient and cost effective, etc.In addition, the use of very high concentration of compound expander of osmolality in the fluid umedecedor proved to be remarkably effective.
