Fixation of medical tubing with fluidum filled chamber

A method of securing a catheter to a support, the method comprising:

• fixing a medical device to the support;
• and
• securing the catheter to the medical device,
• wherein:
• the medical device comprises:
• a base element, the base element comprising a first side fixable to the support, and a second side opposite the first side;
• and
• a top element, the top element comprising a first side connectable with the second side of the base element;
• when the first side of the top element is connected with the second side of the base element, the top element and the base element are arranged for forming a feedthrough for the catheter between the second side of the base element and the first side of the top element, and
• at least one of the base element and the top element comprise a deformable chamber, exclusively filled with air or any other type of gas, the deformable chamber arranged such that, when the first side of the top element is connected with the second side of the base element, the catheter is locally tightly held between the base element and the top element when positioned therebetween;
• the base element, or the top element, or both the base element and the top element, comprises a rigid material that guides the deformable chamber to deform within an enclosed volume which surrounds all sides of the deformable chamber, arranged such that the deformable chamber is fully enclosed and forced to at least partially engulf the catheter;
• and
• the medical device is configured to secure catheters having a range of diameters.
