| Collecting data from various medical devices associated with a patient at one location and sending it to a caregiver at another location in an integrated format is a challenge in telehealth systems. This challenge comes from following factors. First, these medical devices are not equipped with long range communication technologies. Second, medical devices from different manufacturers lack interoperability. Third, communication time is inconsistent. In order to address above challenges, a Continua compliant Wireless Medical Gateway (WMG) is designed and implemented in this research using various hardware components such as BeagleBone Black, Stollmann adapter and Unison Real-Time OS (RTOS). Being complaint to Continua enables interoperability between medical devices from different manufacturers. The selected hardware and software provide easy interface for data transfer over long range. The prototype has been tested extensively using various scenarios to calculate the total communication time, delay consistency and data accuracy. The results show the consistent deviation in communication time for WMG. |
