A telemedicine system based on a modified version of the Bluetooth wireless protocol can transfer patient data, such as medical images from patient to the healthcare provider's mobile device for patient assessment almost four times as fast as conventional Bluetooth and without the intermittent connectivity problems, according to a paper in the forthcoming issue of the International Journal of Medical Engineering and Informatics.
Telemedicine is a rapidly developing technology of clinical medicine where medical information is transferred via telephone, the internet or other networks for the purpose of consulting as a remote medical procedure. However, there are drawbacks to using direct connections between monitoring devices and the healthcare provider, not least the intermittency of standard connections.
Now, T. Kesavamurthy and Subha Rani of the PSG College of Technology Peelamedu, in Coimbatore, India, have devised a dedicated embedded system that uses the short-range Bluetooth wireless networking protocol to connect patient data to the network and then on to the healthcare provider. This avoids the problem of trying to ensure that a viable connection between monitoring devices and the internet or cellular phone network is maintained constantly.
The team has demonstrated a specific application of their technology which involves the transfer of patient medical images (CT scans) to the healthcare provider's personal digital assistant (PDA) device as an example of how Bluetooth might work for telemedicine.
