Abstract

An apparatus to remove liquid from a ventilation system can include a housing, a first port extending into an interior volume of the housing and a second port extending toward the first tube, into the interior volume, separated from the first port by a gap that is at least 5 mm in length, such that ventilating fluid transfers from the first port to the second while secretions and condensate escape through the gap, to be trapped in the housing. The first port joins with a ventilator. The second port joins with an intubation tube coupled to a tracheostomy or endotracheal tube. An extraction port is in a floor of the housing so that accumulated liquids in the housing can drain downward and out the extraction port, while minimizing positive end expiratory pressure loss in the ventilation system, and without exposing caregivers to biological material in the drained liquid.
