Using Convexity

Ostomy Care Tips

General Information

• Convexity may be recommended to increase the wear time of a pouching system.

When used correctly, convexity may help to improve the contact of the skin barrier

with the skin surface.

Definition

• Convexity is the outward curving of the pouching system that comes in contact with

the skin around your stoma. Usually this is the skin barrier.

• Convex describes a shape. Skin barriers are either convex or flat.

Convex barrier helps provide contact with

skin around stoma.

Stoma that is below skin level.

When to Use Convexity

• Convexity may be recommended when:

- you are experiencing leakage or unacceptable wear times with a flat skin barrier.

- your stoma is flush with the skin level or below skin level.

- the skin around your stoma is soft with poor muscle tone.

- there are irregularities in the surface of the skin around your stoma

(for example, soft creases, scars).

How to Create Convexity • Convexity may be built into the pouching system you use. This may be in a one-piece or a two-piece pouch. If you look at the surface of the skin barrier that sticks to your skin, you will notice that it curves outward. • Convexity may be added to the pouching system you currently use. This may be done by adding barrier rings to the back of the skin barrier on your pouch. You may wish to refer to the Ostomy Care Tip on Adapt Barrier Rings and Adapt Convex Barrier Rings.
