摘要：
A breath sampler (100) for collecting a breath sample from a patient is disclosed. The breath sampler comprises a non-rebreather part (110) comprising a sample inlet (130), a one-way outlet valve (160) downstream of the sample inlet (130), and an air inlet (140). The one-way outlet valve (160) and the sample inlet (130) define a first portion of an internal breath flow pathway therebetween. The air inlet (140) is arranged to be closed by a one-way inlet valve arranged to allow air to enter the nonrebreather part (110). The breath sampler also comprises a sample delivery part (120) in fluid communication with the non-rebreather part (110) at an upstream end via the one-way outlet valve (160). The sample delivery part (120) defines a second portion of the internal breath flow pathway, and comprises an air diverter (170), a sample outlet (190), a return inlet (195) and a sample collection chamber connector (150). The air diverter (170) is arranged to divide the sample delivery part (120) into an upstream portion upstream of the air diverter (170) and a downstream portion downstream of the air diverter and is configured to divert the breath sample into a sample collection chamber (200) comprising a liquid capture interface. The breath sampler further comprises the sample collection chamber (200) coupled to the sample collection chamber connector, the sample collection chamber comprising a liquid capture interface.L'invention concerne un échantillonneur d'haleine (100) pour collecter un échantillon d'haleine d'un patient. L'échantillonneur d'haleine comprend une partie de non réinspiration (110) comprenant une entrée d'échantillon (130), une soupape de sortie unidirectionnelle (160) en aval de l'entrée d'échantillon (130), et une entrée d'air (140). La soupape de sortie unidirectionnelle (160) et l'entrée d'échantillon (130) définissent une première partie d'un trajet d'écoulement de respiration interne entre celles-ci. L'entrée d'air (140) est conçue pour être fermée pa
