System and methods and portable base for bowel irrigation

A portable base for a system for irrigating the bowels of a user, comprising:

• a canister unit comprising a volume for an irrigation liquid and an annular neck portion circumscribing an opening around a central vertical axis of the portable base;
• and
• a lid unit configured to be positioned on the annular neck portion and over the opening for closing of the canister unit, the lid unit having an axial extent along the central vertical axis between a top and a bottom of the lid unit, and comprising an annular rim portion and an annular skirt, the annular skirt configured to be partially rotatable relative to the annular rim portion when the lid unit is positioned aright on the annular neck portion;
• wherein a radially outward facing surface of the annular neck portion of the canister unit comprises at least one projecting jut;
• wherein a radially inward facing surface of the annular skirt of the lid unit comprises at least one thread;
• wherein a sealing is provided at the annular rim portion to seal between the canister unit and the lid unit in a locked configuration of the portable base;
• wherein the sealing is movable in response to a force exerted by the annular neck portion;
• and
• wherein rotating the annular skirt relative to the annular rim portion causes the at least one thread of the annular skirt to engage with the at least one jut of the annular neck portion and thereby move the sealing and lock the lid unit onto the canister unit in the locked configuration of the portable base.
