Document Type and Number:
WIPO Patent Application WO/2022/061550
Kind Code:
A1
Abstract:
A breath-sample contained (100) comprising an inlet (102) for receiving a breath sample, a wall (104) at least partially defining a chamber (106) for containing the breath sample, and a valve (110) between the inlet (102) and the chamber (106). The valve (110) is in fluid communication with the inlet (102) and the chamber (106), and is configurable between at least a first open configuration (110a) for flow of breath sample from the inlet (102) to the chamber (106) up to a first flow rate, and a second open configuration (110b) for flow of breath sample from the inlet (102) to the chamber (106) at a second flow rate greater than the first flow rate. Once the valve (110) has been configured in the second open configuration (110b), the valve (110) cannot then reconfigure itself to the first open configuration (110a).
