An anal probe for use in connection with anal irrigation is provided. The probe comprises a tip part and shaft part, which may be separate from each other or one integral part. The probe is provided with retention means, which together with the tip part and the shaft part define a lumen. The probe is further provided with a pressure-sensitive valve. The probe has two configurations, a first configuration in which the inlet to the tip channel is closed and a second configuration in which the inlet is opened. The transition between the first configuration and the second configuration is controlled by the pressure-sensitive valve. During use, irrigation fluid will be pumped into the lumen and the inlet to the tip channel will be opened.
