ABSTRACT:
The present invention is a liquid water trap for continuous trapping of liquid from the gas passed by a pressurized breathing circuit of a ventilator, respirator, anaesthesia unit or the like. A hollow, spherically shaped member has a plurality of holes through its surface. A pair of tubular members extend from within the spherically shaped member, through the surface thereof, and radially outward therefrom, with the first end of each tubular member positioned within the spherically shaped member such that the first ends are separated and overlap in the central region of the spherically shaped member. The second ends of the pair of tubular members are adapted for connection in a pressurized breathing circuit for passage of the breathing circuit gas therethrough. A drain tube member is wrapped about the exterior of the spherically shaped member and has a smaller diameter than the pair of tubular members, with a plurality of holes on one side only of the drain tube member, the drain tube holes being substantially the same size as and overlying the spherically shaped member holes, so that liquid water lying in the lowest lying region within the spherically shaped member flows through the spherically shaped member holes and the drain tube holes and drains out the drain tube.
