The invention relates to an, for patients with faecal/urinary incontinence, auxiliary device in the form of a, on the skin around the anus, glued collection bag made of suitable and skin-friendly plastic that is foldable 180 degrees in the patients front or back position. The design eliminates or substantially reduces the direct contact with faeces and thereby reduces the instances of possible contamination. The collection bag is equipped with channels for water rinsing 9, ointment application 10 and deodorising filters F. The collection bag can be used continuously for several days. The collection bag can easily be removed from the patient by means of the top 6 being made of light-sensitive adhesives. When the collection bag is removed, the bag can easily be sealed with the lid 8 and transported by means of the carrying handle 7.
