  • Patent number: 10420910
    Abstract: A breathing mask has a mask body surrounding a cavity that is open towards one side and is intended for coming into contact with a human face around the mouth and/or nose. A valve arrangement is provided in the mask body with an inspiration valve, for controlling the flow of gas from a port for a breathing gas feed device for providing a breathing gas into the cavity, and an exhalation valve for controlling the flow of gas from the cavity into the surrounding atmosphere. An emergency breathing valve, controlling gas flow from the atmosphere surrounding the breathing mask into the cavity, has a pressure threshold, to allow gas flow, that is lower than an inhalation valve pressure threshold. The pressure thresholds at which the respective inhalation valve and the emergency breathing valve open are coordinated by the closing element being designed as a separate component of the valve arrangement.

  • Patent number: 9968750
    Abstract: A ventilatory assist system and method are disclosed. The system comprises a tube for connection to a patient's airway, inspiratory and expiratory tube lumens connected to the tube, an inspiratory air source connected to the inspiration tube lumen, and a controller of air pressure in the expiratory tube lumen. The pressure controller is responsive to a physiological breathing signal representative of patient's inspiratory effort to allow air flow through the expiratory tube lumen during a patient's expiration phase, partially restricting the air flow through the expiratory tube lumen to a so minimum air flow during a patient's inspiration phase. During both respiratory phases, a unidirectional air flow is produced through the inspiratory and expiratory tube lumens to prevent air expired by the patient from being breathed again. The physiological breathing signal allows synchronization of the ventilatory assist with breathing efforts of the patient.

  • Publication number: 20130112204
    Abstract: The function of a respiration system, with a patient port (1) with connected inspiration branch (3) and expiration branch, is checked. A rebreathing line (9) connects the inspiration branch to the expiration branch. A reservoir (25) is connected to a reservoir port (27) in the rebreathing line. An actuatable control valve (29) is provided in the rebreathing line between the expiration branch and the reservoir port. A pressure sensor (33) is connected to the rebreathing line. A control unit (39) is connected to the control valve and to pressure sensor. The process includes closing the control valve for a preset inspiration time and opening it for a preset expiration time. The value sent by the pressure sensor is detected with the control valve opened during the expiration time and compared with a preset first threshold valve. An error message is generated when the value sent exceeds the first threshold value.

  • Patent number: 8240307
    Abstract: An apparatus (1) for non-invasive mechanical ventilation comprises a fan (2) of Bi-level type, or BiPAP, for generating an air flow according to a succession of inspiration steps, or IPAP, and exhalation steps, or EPAP. The flow is conveyed in the aerial ducts of a patient (25) by means of a flexible tube (3) connected to a nasal mask (4). A flexible air reservoir (5) is provided pneumatically connected to the duct (3) and the nasal mask (4) in order to subtract from the inspiration flow a certain air amount before that it reaches the patient (25) at the beginning of an IPAP step. During the exhalation EPAP step, since the air flow pressure decreases automatically, there is the emptying at least partial of the flexible air reservoir (5), whereas the air exhaled by the patient exits through an opening (14) made on the nasal mask (4).

  • Patent number: 8240308
    Abstract: The present invention relates to a respiration valve (401) for performing respiration tests on e.g. humans, consisting of at least three ports, a first mouth port (402) and two breathing ports (403, 404). The breathing ports (403, 404) comprise pneumatic pinch valves consisting of a channel (101) with a flexible wall (201) to be used for the flow of material and molded as an integrated part of a surrounding chamber (102). The flexible wall (201) comprises two opposing angularly interconnected wall segments (202) which are angularly connected at interconnection points (203) and which flexible wall (201) is pinched by a pressure from fluid, such as air, introduced into the chamber (102). The cross sectional shape corresponds in one embodiment approximately to a elongated hexagon. The construction of the respiration valve (401) comprising these pneumatic pinch is valves enables a very small, light, hygienic, and safe yet inexpensive construction with a long life expectancy.

  • Patent number: 8176917
    Abstract: An emergency oxygen supply system for use on aircraft in the event of a loss in cabin pressure is configured for delivering allotments of oxygen and timing the delivery such allotments to each passenger so as maximize the efficiency of the transfer of such oxygen into the passenger's bloodstream. The delivery of each allotment is selected so that the entire allotment is available for inhalation into the region of the lung most efficient at oxygen transfer while the volume of the allotment is selected to substantially coincide with the volume of such region of the lung.

  • Patent number: 7886740
    Abstract: Minimal concentrations of CO2 are mixed with pressurized air to provide a gas mix effective for stabilizing breathing of target patients or users. CO2 concentrations below about 2% and preferably between about 0.5% and 1.25% are employed. A gas modulator includes a gas mixing module, a sensor and a control processor. The gas mixing module mixes plural gases, including CO2, into a gas mix, for delivery to a substantially leak-proof patient face mask. The sensor, located substantially at the face mask, measures CO2 concentration in the face mask. The control processor, based on a signal from the sensor, controls the CO2 concentration in the gas mix.

  • Patent number: 7836881
    Abstract: In one embodiment, the invention provides a device for decreasing intracranial or intraocular pressures. The device comprises a housing having an inlet opening and an outlet opening that is adapted to be interfaced with a person's airway. The device further includes a valve system that is operable to regulate respiratory gas flows through the housing and into the person's lungs during spontaneous or artificial inspiration. The valve system assists in lowering intrathoracic pressures during each inspiration to repetitively lower pressures in the venous blood vessels that transport blood out of the head to thereby reduce intracranial or intraocular pressures.
