This topic is all about finding a way to create a skin-friendly barrier around a stoma without using adhesive. The main idea is to use a thick, flexible "O-ring" that sits against the abdomen, held in place by a belt or strap with a spring or tensioning mechanism. Here are some ideas and insights shared by others:

1. **Material Considerations**
- Solid silicone O-rings can be too stiff, so softer silicones or custom sizes might be needed.
- Memory-foam or inflatable rings covered with a thin silicone skin are being considered.

2. **Holding the Ring in Place**
- A standard StealthBelt might not be stretchy enough; a belt with an extra-elastic Spandex panel could help maintain pressure.
- A square-edged ring with ribs on both contact surfaces might resist sliding.

3. **Alternative Concepts**
- An inflatable O-ring or a memory-foam O-ring covered with a thin silicone skin.
- Applying a very thin skin-barrier film first so the silicone surface grips without adhesive.

4. **Potential Benefits**
- No adhesive allergies, reusable components, minimal supplies to carry, easier cleaning, and better healing of skin outside the ring area.

5. **Spring-Loaded or Compression Ideas**
- A "radiator-cap" style, spring-loaded collar with a central opening could provide constant pressure.
- A specially fitted Nu Hope hernia belt might be adapted to hold a seal in place.

6. **Existing Non-Adhesive Options**
- Nu Hope Non-Adhesive Pouch uses a silicone O-ring attached to a belt for those with severe skin allergies.
- Coloplast Assura two-piece irrigation sleeve has a curved faceplate intended to seal without adhesive.

7. **Attachment and Stability Ideas**
- Elastic belts with highly stretchable Spandex sections over the ring to maintain steady pressure.
- Magnetic rings were mentioned but could pose risks of skin breakdown and metal allergies.

8. **Cautions and Warnings**
- Inserting anything into the stoma can cause the stoma wall to prolapse and is strongly discouraged.
- Excessive suction or pressure may injure skin or provoke herniation.
- Implanted electronic or hydraulic sphincters have high complication rates and should be approached with caution.

9. **Miscellaneous Resources and Brands**
- Nu Hope (non-adhesive pouch, hernia belts)
- Coloplast Assura 12836 irrigation sleeve
- Convatec (appliance compatible with Nu Hope belt)
- StealthBelt (elastic pouch-support belt)
- DIY ideas include using plastic wrap with a rubber band or modified frames, and even contacting engineers for innovative solutions.

These ideas aim to help those looking for non-adhesive solutions to manage their stoma care more comfortably and effectively.
