Irrigation system with mechanical fluid pressure control

An irrigation system for anal and/or stomal irrigation, the irrigation system comprising:

• a reservoir for an irrigation liquid;
• a tubing system with a first end connectable to the reservoir, and a second end connectable to a catheter or an adapter for provision of a first fluid path for the irrigation liquid between the reservoir and the catheter comprising a distal end for expelling irrigation liquid from the catheter;
• and
• a pump operable to pump the irrigation liquid from the reservoir to the second end of the tubing system,
• wherein the irrigation system comprises a mechanical pressure control device, the pressure control device having an inlet side and an outlet side, wherein the inlet side is connected to a reservoir side of the first fluid path and the outlet side is connected to a catheter side of the first fluid path, wherein the pressure control device is configured to keep liquid pressure on the outlet side less than a first pressure threshold, wherein the irrigation system comprises a user control interface housing attached to the tubing system, and wherein the pressure control device is arranged in the user control interface housing or between the user control interface housing and the second end of the tubing system.

Method for operating an irrigation system for anal and/or stomal irrigation, the irrigation system comprising a tubing system with a first end connectable to a reservoir, and a second end connectable to a catheter for provision of a first fluid path for the irrigation liquid between the reservoir and the catheter comprising a distal end for expelling irrigation liquid from the catheter;

• and an adapter comprising a first connector, and a second connector, wherein the first connector and the second connector are connected by a first fluid path for feeding irrigation liquid from the first connector to the second connector, the adapter comprising a pressure control device arranged in the first fluid path, wherein the pressure control device has an inlet side and an outlet side and is configured to keep a liquid pressure on the outlet side less than a first pressure threshold, the method comprising
• coupling the first connector of the adapter to the second end of the tubing system;
• coupling a catheter to the second connector of the adapter;
• and
• pumping irrigation liquid through the first fluid path.
