Ostomy products

One-piece and two-piece architectures

In a one-piece system, the pouch and skin barrier are joined. A two-piece system attaches a pouch to a separate barrier through an intended coupling. This distinction concerns appliance architecture rather than the number of items inside a box. Coupling diameter and the skin opening also describe different areas. A relationship between these measurements cannot be assumed from one number alone. The attachment structure, opening and overall pouch dimensions are separate parts of the specification.

Pouches and collection purposes

Closed pouches, drainable pouches and urostomy pouches have different outlets and collection functions. Transparency, inspection windows and textile coverings can add further distinctions according to the model. These features do not alone establish whether the appliance is intended for digestive or urinary use. The closure or drainage system is a functional component and differs from a protective cap or separate connector. Pouch size, outlet construction and the location of the coupling provide complementary ways to describe the complete collection appliance.

Skin barriers and separate accessories

The skin barrier provides contact and fixation according to its construction. Flat and convex barriers have different geometries whose selection cannot be determined by a broad category. Rings, pastes, films and other accessories have their own functions and compatibility. The same apparent coupling diameter does not establish interchangeability between systems. Intended combinations remain those documented for the appliance. A complete description therefore distinguishes the pouch, barrier, coupling and accessory functions instead of treating every component as one universal ostomy fitting.
