1. An adjustable gaseous fluid extractor assembly, comprising:
a first portion;
a second portion;
a pivot mechanism providing that the first portion is pivotable relative to the second portion about respective first and second axes, the pivot mechanism comprising a first pivot joint defining the first axis, a second pivot joint defining the second axis, and a link that extends between the first pivot joint and the second pivot joint, the link having a first end connected to the first pivot joint and a second end that is opposite the first end and is connected to the second pivot joint,
wherein the first and second axes are oriented perpendicular to each other;
a flexible tubing element coupled to the first portion and second portion; and
wherein the pivot mechanism is arranged exterior the flexible tubing element,
wherein in a neutral state, the adjustable gaseous fluid extractor assembly extends along a central longitudinal axis, such that the flexible tubing element is entirely linear and the first and second axes are oriented perpendicular to the central longitudinal axis, wherein, in said neutral state, the first axis is positioned nearer a front end of the flexible tubing element than the second axis, and wherein the pivot mechanism is symmetrically arranged for simplified handling of the adjustable gaseous fluid extractor assembly, wherein the first pivot joint comprises a pair of first pivot joints about which the first portion is rotatable, the first portion comprising a first arm having one of the pair of first pivot joints and a second arm having the other of the pair of the first pivot joints, and the second pivot joint comprises a pair of second pivot joints about which the first portion is rotatable, the second portion comprising a third arm having one of the pair of second pivot joints and a fourth arm having the other of the pair of second pivot joints, and wherein the link comprises a first link and a second link, the first link coupled between the first pivot joint of the first arm and the second pivot joint of the fourth arm, and the second link coupled between the first pivot joint of the second arm and the second pivot joint of the third arm.
