碩士 === 國立交通大學 === 網路工程研究所 === 98 === This thesis proposed an information integration system, iPCA, which integrated the wireless sensor network (WSN), WiFi and 3G network to help anesthesiologists providing better post-operative pain control. To reduce labor work and to collect analgesic usage information and physiological data efficiently, we connected three kind of medical instruments with WSN end point through WSN and WiFi. We used the simple encryption and retransmission mechanism to make the data transmitted in the secure and reliable way. We also designed a WSN/3G wireless gateway to bridge the WSN network and 3G network. Thus, the patients can equip with our system as long as he is under the coverage of 3G network. To verify the feasible of our system, we did the field trial in the Changhua Christian hospital to help the medical staff monitor the patient’s health conditions, and provide the patient a real-time notifying system via the short message service to alert the medical staff about the abnormal status. The results showed the iPCA system can actually work well for the real patient, and the iPCA system also provided better post-operative pain control and an efficient way to collect the PCA usage information for medical staff.
