Abstract: A medical line organizer that can include multiple attachable guides for separating and visually distinguishing between attached medical line guides is provided. The guides can be attached to each other or to one or more couplers for attachment to a structure. Various identification techniques can be used to distinguish the guides from each other for identification of individual lines. Additional guides or markers with similar indicia can be placed on the lines to aid in identifying the path of a line within a particular guide.
