A number of patients are suffering from respiratory diseases, such as dyspnea, sleep apnea syndrome (SAS), asthma and chronic obstructive pulmonary disease (COPD). These patients can be supported by early detection of symptom and administration of mild treatment. However, it is a serious burden for them and their family to care for their respiratory conditions in daily life. In this context, we have proposed a new home-care system for such patients. The system is an automatic nebulizer control system based on continuous respiration monitoring. We employ a mask-type unit to install a measurement sensor for respiration together with a nebulizer. Respiration is monitored using a thermocouple in the mask. Respiratory rate is measured by counting peaks of temperature change due to expiration and inspiration. In addition, a capacitance microphone is positioned into the same mask to detect the sound of cough. We confirmed that the proposed system could measure respiratory rate accurately and detect the change of respiratory condition and the cough. We also confirmed that nebulizer was controlled based on the obtained respiratory information and the respiratory information could be shared with medical doctors and family through a computer network.
