A convex ostomy wafer is a medical skin barrier with a curved or outward-shaped profile around the stoma opening. It is used as part of an ostomy pouching system to help attach the pouch to the skin around the stoma and create a seal for collecting output.
Convex wafers are designed differently from flat wafers and may provide gentle outward pressure around the stoma area depending on the product design. They can vary by convex depth, firmness, opening size, barrier material, adhesive type, cut-to-fit or pre-cut style, flange size, and pouch compatibility, so product details and healthcare guidance should be reviewed carefully before ordering.
