Pressure redistributing mattresses are a popular and proven aid in the prevention and treatment of pressure ulcers. The problem is that they are powered by small air pumps and commonly, their vibration can be enough to disturb sleep. The noise generated by many air mattresses and cushions can be intrusive, affect the interaction with carers and spoils activities such as reading or watching television.
The design team at Squirrel Medical tm decided to meet this challenge head on and in 2009, started real time research looking into ways in which to produce Whisper Quiet pumps to power their air mattresses and cushions. The team decided to modify the internal compressors. This confidential Action has enabled Squirrel Medical tm to create a suite of high specification digital pumps that are near silent.
