Description

  In current medical practice, it is necessary to have equipment to monitor vital signs such as electrocardiograms, sphygmomanometers, thermometers, and pulse oximeters. However, nurses consequently have to spend a lot of time checking patients’ vital signs appropriately by attaching and replacing electrodes, as well as reading and recording values. To alleviate this burden, we are developing“an earphone-type vital signs-monitoring device”in order to：1）check patients’ vital signs easily without having to attach electrodes, 2）transmit data wirelessly, and 3）allow the medical staff to monitor the data on portable terminals in real time. So far, we have made a prototype earphone-type single transducer to detect the heart rate. In its performance evaluation, our new device displayed marked positive correlations with the measurement by a conventional monitoring device. In the future, we will evaluate the performance to detect other vital signs with a greater number of subjects, and develop prototypes with shapes and materials to withstand prolonged use.
