DEVICE AND METHOD FOR PULMONARY FUNCTION MEASUREMENT

摘要

The present invention relates to a device for pulmonary function measurement in a subject. The device comprises a means for providing an aerosol comprising particles to be inhaled by the subject, and a means for analysis of a portion of air exhaled by the subject, wherein said particles are hydrophobic and are within the range of 20-200 nm, preferably 50-100 nm, and wherein said portion is exhaled after exhalation of a volume corresponding to dead space. Furthermore, the present invention relates to the use of such a device, a method for pulmonary function measurement in a subject, and a control system for a device for pulmonary function measurement in a subject.

主权项

1. A device (1) for pulmonary function measurement in a subject, the device comprising
means (3) for providing an aerosol comprising hydrophobic particles within the range of 20-200 nm, preferably 50-100 nm, to be inhaled by the subject, the means (3) for providing an aerosol comprises a reservoir (4), means (6, 10) for determining the amount of particles in inhaled aerosol and exhaled aerosol, and a system of valves being openable to the subject, being openable to a means (7) for providing air for inhalation, being openable to the reservoir (4), and being openable to the means (6, 10) for determining the amount of particles in inhaled aerosol and exhaled aerosol, wherein the system of valves is operable such that the means (6, 10) for determining the amount of particles in inhaled aerosol and exhaled aerosol analyses a portion of aerosol exhaled by the subject, wherein said portion is exhaled after exhalation of a volume corresponding to dead space.
