The ObboMed UltraAir Alternating Pressure Ulcer Prevention Mattress – OB-3650 is a medical-grade solution engineered to protect skin integrity, enhance comfort, and simplify caregiving for patients confined to bed for extended periods. Prolonged pressure, heat, and moisture are major contributors to pressure injuries, and standard mattresses fall short in addressing these risks. The OB-3650 combines alternating pressure therapy, dynamic low air loss airflow, and lateral rotation to actively redistribute pressure, regulate moisture, and support healthy circulation—making it ideal for pressure ulcer prevention and wound care.
\nDesigned for hospitals, long-term care facilities, and home healthcare, the OB-3650 UltraAir mattress delivers total bedside comfort with integrated massage and warming therapy for added relaxation and respiratory support. Patented toileting and shampoo systems reduce patient movement and caregiver strain, while the patented inflatable guardrail enhances safety. This advanced pressure-relief air mattress offers a complete, all-in-one solution for stage 1–4 pressure sore prevention and recovery.
\n✅ Patented “Easy Go” Bedpan System – One-touch deflation of targeted air cells creates a bedpan opening in ~20 seconds, enabling safe, hygienic in-bed toileting while reducing patient movement and caregiver strain.
\n✅ Patented “Easy Go” Shampoo System – Quickly forms a recessed head section for in-bed hair washing, improving comfort and minimizing repositioning for immobile patients.
\n✅ Patented Inflatable Air-Filled Guardrails – Soft, supportive, one-button inflatable rails with a mid-section opening enhance fall prevention without the injury risk of metal rails.
\n✅ 15° Self-Lateral Rotation – Automatically redistributes pressure to improve circulation, relieve pressure points, and support pressure ulcer prevention.
\n✅ Multiple Rotation Angles (15° / 25° / 40°) – Left, right, auto, and 40° rotation options increase patient mobility, aid respiratory function, and support therapeutic positioning.
\n✅ Integrated Vibration Massager & Body Warmer – Multi-mode vibration helps loosen phlegm and improve circulation, while gentle warming therapy enhances comfort and relaxation.
\n✅ Alternating Pressure Therapy – Actively redistributes pressure to reduce the risk of stage 1–4 pressure ulcers.
\n✅ Dynamic Low Air Loss System (23 LPM) – Built-in airflow fan removes heat and moisture to maintain a dry, skin-friendly microclimate.
\n✅ Fowler / Seating Function – Reinforced torso and seat support prevents bottoming out when the bed is elevated.
\n✅ 24-Hour Power Outage Protection – Cell-on-cell design maintains support during power loss with audio/visual alerts.
\n✅ Sinking Feature with Rotation Protection – Lowers the surface up to 4″ with soft barriers to protect patients during rotation.
\n✅ Patient Centralization System – Keeps the user safely centered throughout alternating pressure and lateral rotation cycles.
