<p>There is disclosed a water trap suitable for use in a mechanical ventilation circuit. The water trap comprises a cap (10) having formed therein an inlet (11) and an outlet (12), a fluid collection vessel (30) engageable with the cap (10), and a rotatable closure (20) interposed between the cap (10) and the fluid collection vessel (30) which includes at least one aperture (22, 23). The arrangement of the water trap is such that the fluid collection vessel (30) is operably linked to the closure (20) such that engagement or disengagement of the fluid collection vessel (30) from the cap (10) causes the closure (20) to be rotated. The cap (10) is formed with an internal partition (16) extending into abutment with the closure (20) so as to define a chamber, such that when the fluid collection vessel (30) is engaged with the cap (10) the closure (20) has a first orientation in which the fluid collection vessel (30) is in communication with the chamber via the at least one aperture (22, 23) in the closure (20), and when the fluid collection vessel (30) is removed from the cap (10) the closure (20) is rotated to a second orientation in which the at least one aperture (22, 23) is located externally of the chamber.</p> |
