  • Patent number: 8528552
    Abstract: A device and a process for controlling a respirator with inclusion of an oxygen saturation value (34) for compensating a device-dependent time response (15), a physiological time response (16) and a measuring method-dependent time response (17) are described. The device-dependent time response (15), the physiological time response (16) and the measuring method-dependent time response (17) are determined in a continuous sequence and a run time of a change in the oxygen concentration from the metering means (9) in the respirator to the patient (4) is determined and taken into account in regulating the oxygen concentration.

  • Patent number: 8500088
    Abstract: An anesthetic container includes a receptacle for holding the anesthetic and having a wall defining an interior space and a passage in fluid communication with the interior space. The container also includes a valve assembly that is attachable or is attached to the receptacle to control flow of anesthetic through the passage in the receptacle to a vaporizer. The valve assembly has a closed configuration when the flow of anesthetic from the receptacle is limited and an open configuration when the flow of anesthetic is enabled. The valve assembly is constructed so that at least the surface of any component of the assembly that will come into contact with the anesthetic on its storage or passage from the receptacle to the vaporizer is made of a metal or low-density polyethylene, and provides a fluid-tight seal to prevent the escape of the anesthetic without the use of a gasket in the closed configuration.

  • Patent number: 8490621
    Abstract: A device is provided for increasing humidity for respirating patients, especially for a respiration humidifier or an anesthesia reflector. The device includes a gas channel for passing through breathing air, a control and/or regulating device, a temperature sensor and a dew sensor for measuring the humidity present in the breathing air by electromagnetic radiation with a generating device and with a detection device for electromagnetic radiation. The humidity of the breathing air is determined at a low cost and in a reliable manner and condensation is avoided in the respiration system without any additional effort for sterilization. Humidity in the breathing air is determined by the a dew sensor by the change in the reflection of the electromagnetic radiation as a function of dew formation at a condensation-fogged and condensation-free boundary surface between breathing air and a medium having an optical density higher than that of breathing air.

  • Patent number: 8479740
    Abstract: According to various embodiments, a tracheal tube may include an integral humidification system. The tracheal tube may be formed at least partially from a material that is permeable to water vapor but substantially impermeable to respiratory gases. The water vapor may be actively provided to the tracheal tube or may be passively transferred from a patient's surrounding airway space.

  • Patent number: 8479728
    Abstract: Methods and devices for inhalation therapy to deliver and embed (deposit) particles less than about 1 ?m in diameter in the lung. High humidity treatment of the lungs causes condensational growth in particle size upon entering the lungs. Increased particle size is conducive to particle embedment (deposition) in deep lung tissue or at a specific targeted lung region.

  • Patent number: 8375942
    Abstract: A respiration moistener (1) has an inlet (3), into which incoming gas (2) to be moistened can be fed. Vapor (21) is mixed with the incoming gas (2) in a mixing chamber (4). Moistened outgoing gas (5) flows out of an outlet (6). In cases in which the temperature of the incoming gas (2) becomes so high that the temperature of the outgoing gas (5) is above a desired value, the internal desired value is adjusted. The outgoing gas (5) can then cool to the desired value on its way through the inspiration tube (7).
