Hospital patients may no longer need to be hooked up to a tangle of wires, thanks to new technology developed by Fujitsu Ltd. The device enables cord-free monitoring through radio-wave transmission of electrocardiograms, blood pressure and other data from sensors attached to patients’ bodies.
A transmitter mounted on each sensor sends readings to a receiver adjacent to the bed, which will be connected to a dedicated monitor or personal computer. The data transmission utilizes the “medical body area network” (mBAN), a telecommunications standard for medical equipment. The radio waves only have a transmission range of 5 meters and do not interfere with pacemakers or other medical equipment, Fujitsu officials said.
