Telemedicine uses common technologies that provide a conduit for information exchange between physicians nurses and patients. In addition to patient records, medical professionals can obtain vital signs and other reference data through telemedicine applications. also, recent advancement in RF technology and wireless communications has enabled the development of noble networks. Mobile telemedicine involves more than just communicating via mobile phone of PDA that sends and receives medical data on Portable Internet.

This paper describes the design of a mobile telemedicine PDA prototype based on Embedded Linux that can be used to monitor the medical information using a single board computer(SBC).

The device hardware architecture consist of signal conditioning circuit, single chip micro-controller, LCD display and wireless network interface card(W-NIC). Embedded Linux was ported as its operating system and application software was developed QT/embedded 2.3.7.

This system would be very useful for patients with chronic illness, especially in an emergent environment, and for containing medical cost in the aged society.
