Bacterial barrier in flexible tubing extracting wound secretions, used to protect patients from reverse migration of bacteria, includes antimicrobial layer and labyrinth near end of suction tube

摘要

An antimicrobial layer (2) in the interior of the flexible tube, prevents reverse migration of bacteria. At the end of the suction tube (10) a dry labyrinth (9) is formed with the connecting bush (1). The connecting bush is equipped with an antimicrobial layer (2) (e.g. of silver). An antimicrobial bush is placed in the tube interior. The a dry labyrinth (9) forms a dry zone (7) where bacterial growth and multiplication are prevented.
