Abstract: A device for a respirator. A tube is operative to be introduced into a trachea of a patient and supply and discharge gas from the patient's lungs. A first conduit connects the tube to the respirator to discharge exhalation gas. A second conduit extends between the tube and a source of sub-pressure. The second conduit is connected to an exhalation tube of the tube. A third conduit connects the tube to the respirator and supplies inhalation gas. In an active position a valve arrangement keeps the second conduit open and connects the exhalation tube to a source of sub-pressure. In an inactive position the valve arrangement keeps the second conduit closed and the first conduit open. A controller moves the valve arrangement from the inactive position to the active position for a period of time to simulate coughing to cause a gas flow to support transport of secretions.

Abstract: A device for fixing a tube member in a cavity of a patient. The device includes a body that surrounds the tube member and has a casing that at least partly forms an inner space. The body is expandable by supplying a fluid to the inner space in such a way that the fluid in the inner space has a working pressure. Furthermore, the body has, in a non-expanded state, a relatively small outer extent, which permits the introduction into said cavity, and in an expanded state, a relatively large outer extend, which permits fixing in said cavity by abutment with a contact pressure against a tubular wall of the cavity. In order to ensure a tight abutment against the wall of the cavity, the body has such a geometrical shape that the contact pressure is substantially constant independent of variations of the working pressure within a normal working range.

Abstract: The invention refers to a device for collecting liquid from exhalation gas from a patient. The device includes a first pipe conduit (5, 8) for the supply of inhalation gas to the patient, a second pipe conduit (6, 9) for the removal of exhalation gas from the patient and a container device (1) for collecting liquid from the exhalation gas. The container device includes a first space (2), which forms a portion of the first pipe conduit (5, 8) and through which the inhalation gas thus flows, and a second space (3), which forms a portion of the second pipe conduit (6, 9) and through which the exhalation gas thus flows. The second space (3) is arranged to receive the collected liquid. The first space (2) is separated from the second space (3) by means of a wall member (4), which has a good thermal conductivity and permits transfer of heat from the exhalation gas to the inhalation gas.

Abstract: Then invention refers to a device for a respirator. A pipe member (2) is arranged to be intodruced into the tracheaof a patient. The respirator (1) is arranged to supply inhalation gas va the pipe member (2) to the lungs of the patient and to discharge exhalation gas via the pipe member (2) from the lungs of the patient. At least a first passage (5-7) connects the pipe member (2) to the respirator (1) and is at least arranged to permit discharge f he exhalation gas. A second passage (5, 6, 14) extends between the pipe member (2) and a source (13), which provides a sub-pressure. A third pasage connectsthe pipe member to the respirator and is arranged ot perment and supply of inhalation gas. A valve arrangement (20) is, in an active state during a short period of time, arranged to keep the second passage (5, 6, 14) open.

Abstract: An integrated tracheal tube/suction ventilation and co-committal secretion removal device having first and second coaxially arranged conduits where the first interior conduit forms a lumen to deliver gas, and a circumferentially arranged second conduit lumen is structurally adapted to serve as an integral suction lumen for removal of both expiratory gases and secretions. The distal end outlets of both lumens terminate between the device's fixing member and its distal end. The two lumen outlets are arranged such that relative to each other and the device the first interior pipe conduit forming lumen's outlet is located at the distal end and the second pipe conduit lumen's outlet is located at or near the distal side of the fixing member. This selection of relative positioning facilitates optimal deliver of breathing gas to a user in conjunction with removal of expiratory gases and secretions.
