ObboMed OB-3650 UltraAir Complete Pressure Care Mattress System
Designed for patients at risk of or managing Stage 1–4 pressure ulcers, the ObboMed OB-3650 UltraAir Alternating Pressure Mattress delivers advanced pressure relief for individuals who spend 15 or more hours per day in bed. This therapeutic mattress combines alternating pressure therapy and low air loss technology to help reduce sustained pressure, improve airflow, and support skin integrity.
Engineered for both ulcer prevention and treatment, the OB-3650 provides consistent comfort, reliable support, and enhanced patient safety, making it an ideal solution for home care, long-term care, and clinical environments where effective pressure management is critical.
Advanced Pressure Relief & Therapeutic Care
- Customizable Alternating Pressure: Select 10-, 20-, 30-, or 40-minute cycles as air cells alternately inflate and deflate to redistribute pressure, promote circulation, and help reduce the risk of pressure sores.
- 15° Self-Lateral Rotation: Specialized air cells create a gentle 15° side-to-side rotation that redistributes weight, relieves pressure points, supports circulation, and promotes more comfortable sleep.
- Multiple Rotation Angles: Choose from 15°, 25° right/left, 25° automatic, and 40° automatic rotation settings to support mobility, improve positioning, assist with phlegm expulsion, and promote respiratory health.
- Sinking & Centralization: The mattress surface lowers by up to 4 inches while the patented 4-inch guardrail creates an 8-inch soft barrier, helping keep patients safely centered during pressure therapy and rotation—even at 40°.
- Dynamic True Low Air Loss (LAL) Therapy: A built-in airflow fan delivers 23 L/min of air to help remove heat and moisture from beneath the patient, maintaining a dry, comfortable microclimate and supporting skin protection for patients with Stage 1–4 pressure ulcers.
- Fowler & Seating Support: Provides enhanced support beneath the torso and seating areas when the head of the bed is elevated, helping prevent bottoming out and reducing pressure on vulnerable areas.
- Vibration Massager for Phlegm Removal: Four integrated vibration massagers offer multiple modes designed to help loosen chest congestion and facilitate phlegm removal while also promoting relaxation and circulation.
- Integrated Body Warmer: A built-in warming system gently distributes heat along the patient's back to promote comfort, relaxation, and circulation—particularly beneficial for individuals with limited mobility.
Smart Safety & Caregiver-Friendly Features
- Cell-on-Cell Power-Outage Protection: The cell-on-cell design helps prevent bottoming out and can provide up to 24 hours of protection during a power outage when the air hose remains connected. Audio and visual alerts notify caregivers of power interruptions.
- Patented “Easy Go” Bedpan Function: With a single touch, four air cells beneath the buttocks deflate to create a recessed opening for a bedpan in approximately 20 seconds. This simplifies in-bed toileting while reducing unnecessary transfers and caregiver strain.
- Patented “Easy Go” Shampoo Function: One-touch operation gently deflates the head section to create a recessed area for a shampoo basin in approximately 20 seconds, allowing patients to have their hair washed comfortably in bed.
- Patented Inflatable Air-Filled Guardrails: Soft yet supportive air-filled guardrails provide an alternative to rigid metal rails. They inflate and deflate at the touch of a button and feature a mid-section opening for easier patient entry and exit while helping provide fall protection.
