Wireless physiological monitoring system for psychiatric patients

[摘要] This thesis is concerned with the development and testing of a non-invasive device that isunassailable, and can be placed on an aggressive psychiatric patient to monitor the vitalsigns of this patient. Two devices, a glove measuring oxygen saturation and another onthe dorsal part (back) of the patient measuring heart rate via electrocardiography (ECG),skin temperature and respiratory rate were designed and implemented. The data istransmitted using wireless technology. Both devices connect to one central monitoringstation using two separate Bluetooth connections ensuring a total wireless setup. All thehardware and software to measure these variables have been designed and implemented.A Matlab graphical user interface (GUI) was developed for signal processing andmonitoring of the vital signs of the psychiatric patient. Detection algorithms wereimplemented to detect ECG arrhythmias such as premature ventricular contraction andatrial fibrillation. The prototype was manufactured and tested in a laboratory setting onfive volunteers. Satisfactory test results were obtained and the primary objectives of thethesis were fulfilled
