AI Technical Summary

Technical Problem

Existing fecal ostomy bags have a small adhesive area, making it difficult to securely attach them to obese patients with abdominal obesity. They are prone to leakage, and large-area attachment requires high precision, increasing operation time and material waste. Furthermore, they can easily cause skin damage during the removal process.

Method used

A fecal ostomy bag with selectable adhesive area is designed. By setting a cutting area and an extended adhesive area in the adhesive part, combined with a ring-shaped release paper and a drying layer, the adhesive area and size can be selected independently, reducing the skin contact area and enhancing the adhesion strength and comfort.

Benefits of technology

It improves the adhesion of the fecal ostomy bag, reduces the risk of leakage, lowers the risk of skin damage, simplifies the procedure, and enhances patient comfort.
