An irrigation device that includes a reservoir for an irrigating liquid, a catheter in liquid communication with the reservoir, a fixation member for fixation of the catheter and a control unit. The control unit is arranged for in a first position transferring the irrigation liquid to the fixation member and in a second position transferring the irrigation liquid to the catheter. Thereby is provided a simple, inexpensive and essentially maintenance free device which can be used for administrating an irrigation liquid, and which at the same time comprises a fixation member that will not be expelled from the body cavity by e.g. a peristaltic reflex, during use.
