Abstract

A mask configured to be attached to the face of a subject includes a wall section that defines an internal space and covers at least a portion of a nose and a mouth of the subject, an expired gas introduction section that is disposed in the internal space and introduce the subject's expired gas, and a communication section defining a communication channel through which the subject's expired gas introduced from the expired gas introduction section is introduced into an expired gas concentration detection sensor. The position of the expired gas introduction section in the internal space is variable.

Description

Background technique [0001] The present invention relates to a mask attached to the face of a subject so as to direct the exhaled air of the subject to an exhaled air concentration detection sensor. [0002] As an example of such a mask, Patent Document 1 discloses an oxygen mask including a wall portion, an exhaled gas introduction portion, and a vent portion. The wall portion defines an interior volume of the mask so as to cover at least a portion of the subject's nose and mouth. The exhaled gas introduction part is arranged in the inner space so as to introduce the exhaled gas of the subject. The ventilation portion defines a ventilation channel supported by the wall portion, and the subject's exhaled gas is introduced into the exhaled gas concentration detection sensor through the ventilation channel. [0003] [Patent Document 1] JP-A-2011-115543 [0004] The shape of the face to which such a mask is attached is different for each subject. Specifically, the shape of th...
