The Uphealthy Tubular Air Bed (model UH9701) is a specialized medical air mattress designed for bedridden patients to prevent and manage pressure ulcers (bedsores). It features a series of interconnected tubular air cells (often around 22 tubes) that create a cushioned surface. The air cells inflate and deflate in a cyclical pattern (typically every 6 to 10 minutes). This constant shifting of pressure points helps improve blood circulation and prevents skin breakdown.
