This topic is about a new idea for ostomy pouches that use flushable liners. The goal is to make life easier for ostomy users by speeding up the process of changing pouches, adding an extra layer of protection, and potentially reducing costs and waste. The idea was inspired by the needs of a young person with Crohn’s disease and insights from working with a colorectal surgeon.

Here are some key points and advice from the discussion:

1. The design keeps the standard two-piece system with a wafer and flange. It features a wide, resealable top opening for easy liner removal and replacement.

2. The aim is to allow faster changes, provide an extra protective layer, and reduce the need for multiple outer pouches each week.

3. The closure system would use the existing roll-down Velcro style to avoid creating a new type of seal.

4. In tests, the flushable inner bag held two cups of water for about two hours when suspended and over eight hours when inside a standard pouch.

5. The product may appeal to younger users who value speed and discretion, though insurance coverage is uncertain, and the retail price might be higher than current options.

6. Leakage and odor control are major concerns. It's important to ensure the liner does not affect the pouch seal, especially for liquid ileostomy output. Testing with different consistencies is recommended.

7. The system should be easy to handle in real-world situations. Users need to load, remove, and reseal quickly without mess. Prototypes should be tested by actual ostomates.

8. Cost and insurance are significant factors. Frequent changers already find current prices challenging, so obtaining insurance recognition will be crucial.

9. Existing products like Colo-Majic liners and Convatec’s “accordion” flange offer insights. Different adhesive strengths and ease of removal are important considerations.

10. Aesthetics matter to users. There is a desire for new colors, prints, and less medical-looking pouches, with some users wanting pouches that can be a fashion statement.

11. Some users have developed alternatives and workarounds, such as back-flushing drainable bags or irrigating to reduce pouch use.

12. There is general encouragement for innovation in the ostomy market. Users agree that more competition and choice are needed, and real user testing is essential for new products to succeed.
