Setup and Application
Proper application is crucial for preventing leaks and ensuring comfort. Follow these steps carefully:
- Prepare the Stoma Area: Clean the skin around your stoma with water and dry thoroughly. Ensure the skin is free of any oils, soaps, or lotions that could interfere with adhesion.
- Measure the Stoma: Use the measuring guide provided with your supplies to determine the exact size and shape of your stoma. The opening in the adhesive barrier should be no more than 1/8 inch (3 mm) larger than the stoma.
- Cut the Opening: Using small, curved scissors, carefully cut the opening in the adhesive barrier to match the measured size and shape of your stoma. Smooth any rough edges.
- Remove Protective Film: Peel the protective film from the adhesive barrier.
- Apply the Pouch: Center the opening over your stoma. Press the adhesive barrier firmly onto the skin, working from the stoma outwards. Ensure there are no wrinkles or creases in the adhesive. Hold gentle pressure over the barrier for 30-60 seconds to warm the adhesive and ensure a secure seal.
- Secure the Outlet: Ensure the EasiClose WIDE outlet is securely folded and closed before use.
Operating and Draining
The SenSura Mio Convex drainable pouch is designed for easy and hygienic emptying.
- Prepare for Draining: Position yourself over a toilet. Unfold the EasiClose WIDE outlet at the bottom of the pouch.
- Drain Contents: Gently squeeze the pouch to empty its contents into the toilet.
- Clean the Outlet: After draining, wipe the inside and outside of the outlet with a piece of toilet paper or a damp cloth to remove any residue.
- Secure the Outlet: Fold the EasiClose WIDE outlet back up and secure it firmly. Ensure it clicks or locks into place to prevent leaks.
It is recommended to empty the pouch when it is one-third to one-half full to prevent excessive weight and potential leaks.
Maintenance and Care
Proper maintenance extends the life of the pouch and ensures hygiene.
- Pouch Change Frequency: The frequency of pouch changes depends on individual needs and stoma output. Change the pouch system regularly, typically every 1-3 days, or as advised by your healthcare professional.
- Skin Care: Regularly inspect the skin around your stoma for any signs of irritation, redness, or breakdown. If irritation occurs, consult your healthcare professional.
- Disposal: Dispose of used pouches according to local regulations. Do not flush pouches down the toilet.
- Bathing/Showering: The SenSura Mio Convex pouch is water-resistant. You can shower or bathe with the pouch on. Ensure the filter is not submerged for extended periods if possible, or cover it with a filter sticker if provided.
Troubleshooting
Common issues and potential solutions:
| Issue | Possible Cause | Solution |
|---|---|---|
| Leakage | Improperly sized opening, uneven application, worn adhesive, full pouch. | Re-measure stoma and cut opening precisely. Ensure skin is clean and dry before application. Apply firm, even pressure. Change pouch more frequently. Empty pouch when 1/3 to 1/2 full. |
| Skin Irritation/Redness | Leakage, allergic reaction to adhesive, improper removal, infrequent changes. | Address leakage issues. Ensure gentle removal of adhesive. Change pouch regularly. Consult healthcare professional if irritation persists. |
| Pouch Ballooning | Gas buildup, filter blockage. | The integrated filter should manage gas. If persistent, check if filter is wet or blocked. Consider dietary adjustments. |
| Odor | Leakage, improper cleaning of outlet, dietary factors. | Check for leaks. Ensure outlet is thoroughly cleaned after draining. Review diet. The integrated filter should help with odor. |
If you experience persistent issues or have concerns, please consult your healthcare professional or Coloplast customer support.
