• Designed to provide a stable support surface to aid with patient transfer and nursing procedures

Top cover
• Vapour permeable and water resistant, incorporating 2-way stretch and bacteriostatic properties

Integrated audio & visual alarms
• Includes low pressure alarm, power fail alarm and pump fault alarm

• Cell on Cell designed to provide additional supoort and to help increase patient stability

• Electronic pressure setting – allows accurate and appropriate pressure settings to be set for various weight ranges
• Variable cycle times – In addition to a 10 minute cycle time, the Alpha Active 4 system offers the choice of an extended cycle period of 20 minutes, which may be desirable as patients begin to rehabilitate and the risk reduces.
• AutoFirm – provides a stable support surface for patient transfer and nursing procedures.
• 2 Modes of operation
Active / Alternating mode: periodically redistributes pressure away from vulnerable areas by alternately inflating and deflating cells beneath the patient.
Reactive / Static mode: cell pressure is equalised to redistribute the body weight over a greater surface area – ideal for patients unable to tolerate a moving surface
• Audio & Visual alarms – include; Low pressure alarm, Power fail alarm & Pump fault alarm
• Modular construction – contributes to ease of cleaning and maintenance
• Transport Facility – Cell pressures are automatically equalised, leaving an even surface
• Cell-on-Cell – designed to provide additional support and to help increase patient stability
• Static Head Cells – 3 static head cells
• Reliant IS2 cover – vapour permeable and water resistant, incorporating 2-way stretch and bacteriostatic properties
