Aimed at securing the unobstructed communication between the patients and nurses, guaranteed the urgent information reached the nurses' office synchronously when symptoms occur which deprived the patients of ability to connect with the nurse automatically, we design an integrated monitor and calling system based on the wireless sensor network(WSN). The system includes three parts, the removable correspondence device, the physiological parameter sensor and the terminal user device. The system selected CC2530 which support ZigBee protocol as an information transmission module. The system can transmit the instruction via the nodes from the removable correspondence device to the terminal device, which transmit the needs of patient to the nurse immediately. The physiological parameter sensor can collect physical index from the patient (heart rate for instance). The data can be transmitted to the terminate device. In case of the severe symptom rise above expropriating himself of calling at nurse center, the system which had detected the abnormal index of the patient can transfer the emergent instruction to the device so the nurse can monitor the physiological index from patient. The experiment shows the system could bring great convenience for the medical health monitoring.
