The invention relates to a mouthpiece for a medical device. The mouthpiece extends along a first axis from a rear portion to a front portion with a middle portion arranged therebetween. The rear portion is for attachment to a medical device and the front portion is for inserting into the mouth of a user. The middle portion has a cross section parallel with a second axis substantially perpendicular to the first axis. The cross section extends in a direction substantially parallel with a second axis from a first limit to a second limit and has a width substantially perpendicular to both the first and second axes. The cross section includes a divergent portion between the first limit and a widest limit, at which the width is a maximum, and a convergent portion between the widest limit and the second limit. The widest limit is a first distance from the first limit and a second distance from the second limit and the first distance is greater than the second. |
