I. Basic Structure and Materials

1. Core Components: Mobile chassis (frame), detachable cradle bathtub, movable mattress, detachable wire mesh basket, mosquito net

2. Mobile Chassis (Frame), basket:

Material: High-quality steel Q235, environmentally friendly polymer coating (electrostatic powder painted), reinforced with hospital-grade disinfectant resistance, seamless welding, and highly polished joints

Structure: High stability design, no sharp corners/burrs, smooth surface and joints, no obvious welds or workmanship defects at connection points; equipped with a transport handle.

1. Detachable Cradle Bathtub:

Material: High-impact medical-grade acrylic, thickness ≥4mm (fully transparent design, ensuring unobstructed visibility)

Structure: 4 safety contact points at the bottom; perforated bottom (≥10 holes for natural ventilation); rounded tub edge without sharp edges (or integrated special handle); name card holder at the foot (newborn identification)

1. Detachable Mattress Material: Single-section polyurethane with pressure redistribution properties; mattress cover is made of polyurethane (waterproof, breathable, and resistant to medical disinfectants), with pull tabs. 1. Detachable mesh basket
