A medicine delivering tube capable of transporting fluid from an existing medicine dispensing unit to the patient preferably includes a protective sleeve concentrically positioned about the medicine delivering tube such that a lubricant receiving zone is intercalated between an outer surface of the medicine delivering tube and an inner surface of the protective sleeve. The protective sleeve preferably includes a plurality of holes spaced along a major surface area of the protective sleeve. A lubricant dispensing unit is in fluid communication with the protective sleeve thereby injecting lubricant into the lubricant receiving zone for reducing friction between the outer surface of the medicine delivering tube and the inner surface of the protective sleeve. In this manner, upon applying an external force to the protective sleeve, the lubricant is caused to egress the protective sleeve via the holes thereby reducing friction along an outer surface of the protective sleeve.
