- convex flextend skin barrier pushes skin back and stoma forward

- activated carbon filter aids in smell reduction. if charcoal filter gets wet, it may lose function

- two piece system needs to get changed twice a week. bag must be emptied once/twice a day

- internal lining contains smell combatting agent

- belts are optional to secure flange in place

- colostomy bags attach to stoma in the colon

- snap must be sealed all the way around to be effective

- must be unsealed as needed to release gas and prevent popping

- if flange is cut to the wrong size, there will be leakage and the flange will not be secured

- bags can fall off due to excess movement

- most two-piece systems are fastened with snaps

- stoma does not contain nerve endings

- mc junction is the connection between skin and stoma

- filters get clogged very quickly

- certain designs contain reusable bags with disposable liners

- non-opaque bags can cause insecurities

- belts not at level will impair flange

Belt Component for security and comfort:

 

Drysuit materials: 

• Provides thermal insulation.

• Water resistant properties allow for water to remain on the outside of the materials

• Made of Neoprene, a synthetic rubber, that encloses tiny gas bubbles and allows for water to be kept out

• Flexible material, but not completely tear resistant. 

• Polyester and synthetic materials are preferred because natural materials as they are better at insulating and preventing leaks, which can be frequent with ostomy patients

• Water-proof but breathable material like Gore-Tex. Prevents excessive humidity and condensation. This function though does not apply to when you are underwater.

• CON: can be hard to put on due to inherent elasticity. 

SLIP materials:

• Can be used to prevent leakage or seeping through of water or wastes. 

• Helpful in preventing infections as it “resists adhesion from colonization of microorganisms”

• Widely useful in the biomedical field

• Self cleaning due to antibacterial agents

Stealth Belt:

• Made of nylon, which is a synthetic, breathable and flexible 

• Stretchiness allows for all day comfort** and double enclosure prevents breakage or slipping off ostomy belt.

 

Seal:

• Newly innovated silicone seal is supple like latex

• Considered very flexible and far more durable

• Hypoallergenic, thus providing the biocompatible portion

• Might need to be clipped on, but can be more useful given a seal lock

Skin Adhesives:

Silicone adhesives

• translucent self-levelling silicone adhesive

• Cures at room temperature (when it is exposed to atmospheric moisture)

• Retains adhesive properties when exposed to water (and sweat)

• Transparent and non-sterile

• Latex free (in case of allergies) -> biocompatible

Inner Lining:

• LDPE low density, but waterproof and tear resistant

• Resistant to impact, moisture and toxic hazards

• Lightweight but strong, and increasingly sustainable

Odour Trapping:

LIFE odor can trap VOCs in the polymer matrix to stop microbes from entering the environment. The LIFE  minimize unpleasant odors.minimizes odours 24/7

Tackling the idea of comfort and stability for Himesh, our group is concerned with the ostomy belt and the seal between the ostomy pouch and flange.

 

For the belt:

• We can use a drysuit or even nylon material. With a thicker width compared to the current ostomy belt, the nylon/drysuit belt will provide extra comfort for Himesh as he participates in his physically demanding lifestyle

• The water resistant material makes it easier to wear while in the shower, as it won’t provide an uncomfortable wet feeling or become heavy against his body

• Providing insulation, but breathable movement, the nylon belt adheres to his activity

• The belt also conceals the ostomy pouch, making it psychologically more comforting to wear (especially in public as “degradation” is a common feeling among ostomy patients) the opacity of the nylon provides this comfort. 

• In addition, the polyester material will be leak proof.

 

For the Seal:

• Using a silicone seal will provide flexibility and durability when it comes to Himesh’s bending and twisting

• A lock seal can be used to provide extra security in case of sudden unexpected movement

• A secure adhesive (that applies silicone to skin) allows for security to the body and the  silicon

• Water resistant properties prove useful when Himesh sweats as the adhesive retains its ability.
