Abstract
There is provided a device for collecting a breath portion from a patient for analysis, comprising a housing structure including an inlet port associated with a mask structure for receiving a portion of the patient's breath, at least one sensor operatively coupled to the inlet port for detecting one or more parameters regarding the patient's breath, at least one collection container for collecting a portion of the patient's breath received in the inlet port, at least one pump for pumping a selective portion of the patient's breath from the inlet port to the at least one collection container and a control system for controlling operation of the at least one sensor and at least one pump. The control system selectively operates the pump based on sensed parameters such as CO2 and/or pressure to collect breath samples.
