Explanations and features: * Steady mode: pressure across the entire mattress calibrates to two-thirds of its capacity, providing a steady treatment of low pressure to allow more immersion in the mattress surface and providing * optimal pressure redistribution. The system will automatically revert to variable mode after 20 minutes. Variable position: Air cells blow and separate continuously to mimic normal sleep movement patterns and relieve stress from areas at risk, while also stimulating blood circulation. * Auto Adjust: The pressure / body weight algorithm enables automatic compression in response to individual body mass distribution and patient movement. * Heel section: one or more of the bottom five cells can be emptied under the patient's heel to create a vacuum, which will enable the heel to swell so that there is no pressure on with the heel region (E polyurethane AP, 2009). * Seat Inflation Mode: Increases pressure evenly across the entire mattress by 5 mmHg to provide optimal support in the deficit area when he's in Fowler mode, which reduces the risk of "going out". Maximum Hardness Mode: Increases mattress pressure to its maximum capacity, to provide a more stable and stable surface during posture adjustments, patient and nursing transportation. System will automatically return to variable mode after 20 minutes * Lock panel: Reduces the risk of tampering with pump settings. * Antimicrobial filter: Provides an additional layer of protection, with antimicrobial agents that kill harmful bacteria, which reduces the risk of mobile contamination among patients. Wire paths: transfer energy and lead down the mattress side to solve the wiring trace problem, which reduces the risk of damage and failure. * Multiple alarms: Provides a visual and audible warning when the system loses air pressure, crashes, or needs repair, reducing the risk of prolonged loss of variable treatment. * Flexible two-way steam cap: Reduces patient anxiety and friction, in addition to providing an easy-to-clean, water-resistant protective film.
