A method for coating a hollow body on its inner surface comprises pre-coating the inner surface with a reactive gas plasma (PECVD), and follow-up-coating the pre-coated surface with a reactive gas component without plasma action (CVD). The resulting hollow body is used for temporarily accommodating bodily liquids, in particular blood, or cell suspensions, due to its hydrophilizing PECVD/CVD-coating on its inner surface.
