Abstract: The invention relates to a device for performing artificial respiration on a patient, comprising a container (1) which defines an inner volume relative to the ambient and has a first opening accommodating a valve arrangement (2, 14) which allows inflow of air or gases from the outer area to the inner area, and a second opening in connection with which there is provided a valve arrangement (3, 16) which allows outflow from the container and prevents inflow to the container through the second opening. An expansible means (7) is provided in the container and adapted to expand upon action from the outer area to displace air and/or other gases in the container (1) out through the second opening. This improves the certainty that oxygen and/or other gas finds its way to the patient's air passages.

Abstract: A training apparatus (10) for the practice of puncturing blood vessels includes a model arm and an air-tight, liquid-tight compressible liquid container (19) and a two-way pressure threshold valve for transferring liquid between the container and the model arm. The model arm includes a core (14) of a solid material, a tight-fitting cover (32) of a penetrable material and at least one penetrable tube (31) provided between the core (14) and the cover (32), one end of the tube being connected to the liquid container (19) and the other end being sealed. The liquid container (19) is integrated into the model arm and disposed in such a manner so as to allow it to be compressed by establishing a pressure on a part of the surface of the model arm.

Abstract: A disposable resuscitator includes an elongated, elastically compressible squeeze bag having a first opening, a one-way valve for the intake of oxygen-containing gas into the bag mounted in the first opening, a second opening which is in airtight communication with a valve housing in the form of a transparent pipe having a pipe stub for the attachment of the resuscitator to a facial mask, and an outlet for exhalation air, the tubular valve housing containing a valve including a valve seat and a disc-shaped valve body of an elastomeric material and having a centrally mounted, projecting guide pin which is axially displaceable in a hole in the valve seat, a body having a central passage forming the outlet for exhalation air being provided in the free end of the transparent pipe, the central passage being surrounded by an annular bead which is located co-axially and in contact with the valve member, the pipe stub for the attachment of the resuscitator to a facial mask extending from the side of the transparent p

Abstract: A protective device kit for use in pulmonary ventilation treatment including a film mask for positioning over a patient's mouth and nose regions and a one-way valve mounted centrally in the film mask and comprising a valve housing having a valve seat provided with inlet openings and having an internally situated valve flap which, in the closed position of the valve, covers the inlet openings of the valve seat, and one or more outlet openings provided in the side wall of the valve housing, and further including a flat box for encasing closely and protecting the film mask in its folded state.

Abstract: A respiratory training apparatus comprises a mouthpiece, a respiration chamber which includes an inspiration chamber having a check valve and an expiration chamber having a check valve. Exchangeable covers are provided for the chambers for varying the air flow resistance. A branch pipe comprising a valve is connected through as flexible tube to the lower end of a manometer's U-shaped tube, and a pipe stub extends from the mouthpiece and communicates with the upper end of one of the tube sections of the U-shaped manometer.

Abstract: An aspirator for removing a body liquid from a body cavity comprising a cylindrical receptacle having a top wall comprising a flap valve, and an aspirating tube, one end of said aspirating tube being connected with the upper part of the receptacle and the other end having such a shape that it can be inserted into the body cavity, said receptacle being partly surrounded by a cylindrical cap-shaped member having a top wall including a flap valve, the cap-shaped member having such a shape that an axial displacement of the cap-shaped member relative to the receptacle produces a vacuum in the space between the cap-shaped member and the receptacle.The aspirator is more compact and of a simpler construction than the corresponding prior art aspirators.

Abstract: A manikin for practicing artificial respiration by the mouth-to-mouth or mouth-to-nose method and comprising an inflatable lung element, a chest element and a head element having a cavity containing a replaceable bag surrounded by an elastically expandable cover having a predetermined internal volume in its state of rest, the bag having an air inlet which is airtightly connected with a replaceable mouth and nose element and the cavity in the head element being connected with the lung element through an air duct. The manikin does not malfunction in case of a leakage in the secondary air system.

Abstract: Simulator for practicing tracheal intubation comprising a manikin head attached to a support and having a skull comprising a movable lower jaw, and a neck connected to the skull and support so as to allow the manikin head to be tilted forwards and backwards, the simulator having an oral cavity and a throat comprising a thin-walled funnel-shaped element having at its upper edge a convex tongue element attached to the lower jaw and having at its lower end two ducts one simulating a trachea and the other simulating a gullet.

Abstract: An anaesthesia-breathing apparatus for supplying gas to a patient for artificial respiration, supported respiration, anaesthesia purposes or combinations of such purposes. The apparatus comprises a gas chamber connected to a patient connection piece, a respiratory gas receptacle, for example in the form of a respiration bag, a first check valve adapted to permit discharge of excess gas from the breathing apparatus to the atmosphere and, optionally a filter for absorption of carbon dioxide from recirculation breathing gas. Security and venting valves are not required for the patient's security during manual operation of the respiration bag because the gas chamber is in communication with the patient connecting piece via a control valve which alternately conducts exhaled gas to one end of a recirculation gas chamber or closes the communication to the recirculation gas chamber and conducts the exhaled gas from the gas chamber to the patient.

Abstract: An attachment device for use in a tracheal aspirator comprising a hand-held container with rigid walls having a secretion inlet opening with an inside diameter sufficiently large to permit passage of solid particles and an outlet opening for connection to the suction tube of a pump. The device further comprises a secretion suction tube of correspondingly large inside diameter and a length just sufficient to enable the device to be operated in front of the mouth of the patient. One end of the suction tube is received by the secretion inlet opening of the container. The inside diameters of the secretion inlet opening and suction tube are between 6 and 12 millimeters and the length of the suction tube is in the range between 200 and 300 millimeters.

Abstract: An expiration valve composed of a valve housing presenting an inlet arranged to be connected to the expiratory outlet of ventilating apparatus, and an outlet, a valve seat disposed within the housing, a valve disc arranged to cooperate in a sealing manner with the valve seat, a member biasing the valve disc into its sealing position against the valve seat in the direction counter to the air flow direction between the inlet and the outlet, and a damping chamber containing a viscous fluid and arranged to cause movement of the viscous fluid within the chamber to damp vibrations of the disc during movement of the disc within the housing.

Abstract: A manually operated lung-venting apparatus includes a self-expanding bladder having a bladder inlet through which treating gas is drawn into the bladder during expansion thereof and a bladder outlet through which treating gas is driven out of the bladder during compression thereof. The apparatus further comprises a valve device having a housing attached to the bladder; and inlet chamber in the housing; a valve inlet for establishing communication between the bladder and the inlet chamber; a valve outlet which is in continuous communication with the inlet chamber and which is adapted to be connected to the respiratory system of a patient.
