Abstract

The present invention provides an inhaler capable of measuring lung function, feeding back the measurements, and administering medicine suitable for a lung condition in a single use. The inhaler 1 ofthe present invention includes a lung function measuring unit 2 having a spirometer for measuring lung function, and, using a computing unit 5, compares the lung function measurements with a medication pattern table stored in a storage unit 7 and determines a disease severity and a diseased region of the lung. Based on the determination results, the computing unit further selects types and particle diameters of medicines suitable for the lung condition, and controls an ejection unit 3 including a plurality of ejection portions to eject the medicines required for treatment in a single use.

Description

technical field [0001] The present invention relates to an inhaler that measures lung function, determines the type and particle diameter of medicine from the measurement results, and ejects medicine suitable for the lung condition. Background technique [0002] Known devices for measuring lung function include spirometers and peak flow meters. Doctors determine the severity of lung diseases such as bronchial asthma and chronic obstructive pulmonary disease (COPD) from the FEV1 (forced expiratory volume in one second) value or PEF (peak expiratory flow) value obtained from the measurement, and Choose the type and amount of drug to be administered. Based on the pattern of the flow-volume curve recording the change of the flow rate (flow rate, flow rate) and volume at the time of maximal exhalation, it is possible to judge the occluded area of ​​the lung. [0003] Inhalers represented by medical inhalers include metered dose inhalers (MDI), dry powder inhalers (DPI) and nebu...
