A branched planar electrode layout detects leakage and moisture spread in ostomy appliances without losing function if one subbranch ruptures.

A branched planar electrode layout detects ostomy leakage and moisture propagation while tolerating subbranch rupture for reliable early alerts.

A branched planar electrode detects leakage and moisture spread in ostomy appliances while preserving signal function under stretching.

A CIE L*a*b*-tuned comfort layer keeps an ostomy pouch opaque when wet, improving discretion under clothing and during swimming.

An inward-projecting spout redirects stoma output into the bag to reduce skin contact, leakage risk, and attachment integrity issues.

A bracing member and shield apply pressure around the stoma to support pouch adhesion, reduce urine leaks, and limit skin irritation.

Electrode-based moisture sensing warns of ostomy base plate adhesive failure early, helping prevent leakage on uneven or moist skin.

A bent filter channel and separation element vent stomal gas while blocking solids and liquids, reducing pouch expansion and leakage.

Varying trace stiffness across skin-contact zones lowers stress at material transitions, improving sensor reliability and leakage alerts.

Sector-based sensors track liquid spread around the stoma to predict leakage direction early and help prevent skin damage.

Replacing pVDC with an EVOH multilayer film preserves odor blocking in ostomy pouches while enabling scrap reuse and full recyclability.

Discrete protective projections keep ostomy adhesive passages open during storage, preserving adhesion and reducing leakage risk.

Stabilizing extensions and a deformable liner arm improve ostomy seal stability, direct output away from skin, and reduce hydrocolloid waste.

Integrated electrode multiplexing tracks moisture and wetting patterns to signal the right dressing change time and avoid waste or adhesive failure.

A dual-chamber ostomy pouch uses a permeable separation filter and vent to release stomal gas without clogging, reducing ballooning and leaks.

A support panel nests the ostomy outlet valve in a stowed position to seal liquid waste, reduce leakage risk, and keep a flat profile under clothing.

Auxetic cuts let the ostomy sensor patch conform to convex or concave base plates while detecting moisture and adhesive failure before leakage.

Uniform pressure from a contoured ostomy pressing ring improves pouch-to-skin adhesion, reducing leakage, seal failure, and user error.

An angled overlap comfort layer creates a viewing window and foldable fit, extending ostomy pouch use while improving discretion and comfort.

Segmented electrodes in an ostomy base plate detect and classify fluid leakage early, helping users replace the appliance before skin damage.

Conductive electrodes embedded in an ostomy base plate track moisture and adhesive changes to detect leakage before skin damage occurs.

A removable protective layer absorbs stoma mucus during base plate placement, preserving adhesive tack and extending ostomy wear time.

Discrete thicker adhesive zones at the ostomy flange edge absorb more moisture while preserving flexibility for body curvature and movement.

A gasket-sealed connector blocks external moisture from conductive contacts, enabling accurate ostomy leak alerts in wet conditions.

A threaded stem-and-sleeve valve enables controlled urostomy pouch drainage without hand repositioning, helping prevent dripping and spillage.

A crescent prefilter and anti-reflux panel keep ostomy pouch gas vents clear, reducing filter clogging and ballooning.

A multilayer stretch-fabric cap secures the ostomy bag drain end, preventing accidental opening while cushioning skin from rigid edges.

Thin adhesive troughs over electrode paths detect moisture early, while thicker crest regions preserve adhesion and absorption.

Sequentially revealed images on the release layer guide ostomy fitment application, helping users form a reliable seal and avoid leakage.

Integrated dome, cup support, absorbent layer, and drain cap improve stoma security, bag handling, and discreet leak containment.

Three radially spaced electrodes compare resistance changes to distinguish stomal output from sweat and warn of adhesive failure.

Radial electrodes monitor moisture and liquid around the stoma to warn of adhesive failure before ostomy leakage occurs.

Complementary color layers and visible step images help ostomy fitments seal securely while staying less conspicuous on skin.
