Compumedics Sleep Monitoring Technologies

Compumedics, a Melbourne-based group established in 1987, specialises in the development, manufacture and marketing of computer-based medical monitoring and diagnostic equipment. Their latest product to hit the market, the Siesta, is the world’s first wireless amplifier/recorder, able to measure up to 32 inputs from the patient. It was developed to provide greater flexibility for the doctors and patients that use them.

Compumedics offers portable diagnostic systems for laboratory, ambulatory and portable applications, for sleep, neurology and cardiology. Their systems contain up to 64 input channels, for measuring all sorts of physiological variables, and can even be combined to monitor both sleep/polysomnograph (PSG) and electroencephalograph (EEG)-type variables.

The latest product, the Siesta, received USA FDA market clearance in 2001. It has 32 data channels for collection of any physiological variable. There are three ways of powering the Siesta, AA batteries, rechargeable NiMH batteries, or by plugging directly into power. With so many different power options, the Siesta is able to be taken anywhere, anytime. The Siesta’s many functions include the ability to remotely record and monitor all channels through a wireless ethernet link, which can either be stored on computer, or to compact flash cards in the device itself, or both at once. This wireless link enables physicians to monitor their patients when they are out of bed. And since it is only 14 x 7.6 x 3.8 cms, and weighs only 300 grams, it is highly portable. It will revolutionise sleep monitoring, with virtually any hospital bed being able to be used as a sleep study.

Full integration into the network allows Compumedics have also developed digital video software, which allows simultaneous streaming and video recording while variables are recorded. And for all the data generated by these devices. Compumedics have also developed ProFusion software, which assists in the analysis of the information generated. Compumedics have captured 70 percent of the market, and have won numerous business awards, from both the government and other multinational companies.
