Abstract
An outlet valve for an ostomy appliance comprises an axle defining a hollow bore for receiving a liquid output from the ostomy appliance. The axle comprises a curved lateral wall. An outlet element comprises a cap arranged concentrically with the axle and an outlet tube affixed to the cap. A valve opening is defined in the curved lateral wall. The cap is rotatable around the axle to move from a closed configuration in which the valve opening is not in liquid communication with the outlet tube to an open configuration in which the valve opening is in liquid communication with the outlet tube. The outlet valve further comprises an outlet element seal configured to provide: sealing between the cap and the axle around a circumference of the axle; and sealing between the valve opening and the intake opening when the outlet element is in the closed configuration.
