#CMT# #/CMT# The method involves automatically compensating pressure in a container by increasing a volume of a cylinder (1), where a volume of the container is variable and proportional to the pressure of exhaled air. The movement of the cylinder is controlled by a motor (3). The motor is controlled by an exhaled air pressure sensor (6). The cylinder is closed at one side by a flange (13) and another side by a piston (2). #CMT# : #/CMT# Independent claims are also included for the following: (1) a device for collecting alveolar air by a container for consecutive analysis (2) a method for eliminating non-alveolar exhaled air outside a container (3) a device for eliminating non-alveolar exhaled air outside a container (4) a method for transferring the alveolar air to remove markers on an adsorbent or in a cold trap (5) a device for transferring the alveolar air. #CMT#USE : #/CMT# Method for collecting alveolar air exhaled by a human or animal using a container for screening lung cancer, oxidative stress and markers issued from anesthesia in a medical field. #CMT#ADVANTAGE : #/CMT# The method avoids condensation of water contained in the exhaled air, thus increasing the sensitivity of detection of low concentration compounds, and improving separation capacity of the chromatographic column. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of an exhaled air collecting apparatus. 1 : Cylinder 2 : Piston 3 : Motor 6 : Exhaled air pressure sensor 11 : Processor 13 : Flange. |
