SPRAY DRY PROCESS FOR APPLYING ANTICOAGULANT ON A SYRINGE BARREL

摘要

A method for coating a substrate surface, such as an interior portion of a syringe is provided. An aqueous anticoagulant solution is atomized onto the substrate surface and dried by the forced flow of warm air. Water is removed during the drying leaving a coating of anticoagulant. A concentrated aqueous anticoagulant solution is used to reduce the time required for drying. A syringe having an interior portion coated with anticoagulant is also provide d.
