| Summary: | 碩士 === 南台科技大學 === 電機工程系 === 99 === This study designed a set of sensing system to be used when patients register for outpatients visits using RFID (Radio Frequency Identification) system. This system allows doctors and nurses at outpatient clinics to keep track of patients’ status in a dynamic manner so as to reduce time wasting in the process of visit.
This system is a RFID sensing system designed specific for outpatients at the waiting area of a hospital for outpatient visit, which is different from the RFID wristband currently used in hospital. The RFID wristband requires a short distance to make the sensing work and can only verify patients’ identification, but could not know their dynamic status at hospital. In this system, a low-band (125KHz) long-distance RFID reader (sensing distance of 60cm) is adopted, which can react to the electric sensing card (EM card) carried on the outpatient, decode the data on the EM card that sensed by the RFID reader through the self-made Micro Controller Unit. The data are sent to the computer within the diagnosis room so that nurses can know whether the outpatient has arrived at the waiting area, and could arrange the sequence of medical treatment accordingly. Thus, the time wasted in nurses’ looking for or waiting for outpatients who are not in the waiting area will be reduced. Consequently, the efficiency of outpatient visit is increased, and the services for outpatients and inpatients are improved as well.
