Secure-Lid Portable Bedpan Ergonomic Design

Exact size: 38.5 × 26.5 × 10.5 cm; weight: ~450 g; usable volume: ~1.2 L. Built from homopolymer polypropylene — a material selected for UK climate resilience (no brittleness in cold bedrooms or garages) and resistance to common household cleaners. The ergonomic silhouette features a 5° forward incline, chamfered corners, and continuous radius edges (no hard angles) — all contributing to safe, intuitive handling and stable placement. The lid engages via concentric ridge-and-groove interface — requiring no force to attach or remove, yet remaining firmly seated during normal motion. Interior walls are vertically straight near the base to maximise capacity, then gently flare upward for easy wiping access. Surface texture is Class A injection-moulded finish — identical to that used in NHS-approved reusable care aids. Real-world deployment includes: overnight support for dementia patients who wander at night, travel readiness for UK-based retirees touring Europe by motorhome, and emergency preparedness for flood-prone or off-grid homes — proving utility beyond clinical assumptions.
