  • Publication number: 20230321385
    Abstract: The present invention provides a practical method for treating atopic dermatitis. By subjecting patients suffering from atopic dermatitis to filtered temperature controlled laminer air flow disease symptoms have been significantly reduced and even removed. The velocity of the laminar air flow is balanced such that body convections are braked without the generation of draught..

  • Publication number: 20180043128
    Abstract: This invention relates in general to methods and devices for displacing body convection and thereby reducing exposure to allergens and other airborne fine particles within a personal breathing zone during situations of or corresponding to sleep thereby reducing or removing symptoms of asthma and allergic rhinitis while improving quality of sleep and in particular to methods and devices that utilize Temperature controlled Laminar Airflow (abbreviated TLA from herein and onwards). Also, business methods involving such methods and devices are disclosed.

  • Patent number: 8956442
    Abstract: Provided are methods and devices for improving microvascular function in humans and mammals. Reduction of exposure to airborne fine particles using air treatment systems increases microvascular function in persons at cardiovascular risk. Preferred treatment systems provide a zone of clean air having >75% reduction in airborne particle counts around a person at cardiovascular risk. The devices and methods can be optimally used during sleep, when the user is stationary for an extended period.

  • Patent number: 8444747
    Abstract: Methods and devices are provided whereby a controlled personal breathing zone is maintained using temperature controlled laminar air flow (TLA) of filtered air. A substantially laminar, descending flow of filtered air is maintained with a velocity determined by the air-temperature difference between the supplied air and the ambient air t at the level of the personal breathing zone. The air-temperature of the filtered supply air can be carefully adjusted to maintain the velocity-determining difference in air-temperature within the optimum range of 0.3 to 1° C. Thus being able to at the same time displace body convection and achieve comfort.

  • Patent number: 8308536
    Abstract: The present invention relates to a ventilating device for providing a zone (1) of clean air between the ventilating device and a workplace region (2), which ventilating device comprises air supply units (3) adapted to generating laminar air flows intended to constitute said clean air zone. The ventilating device comprises at least three air supply units (3) disposed in a closed pattern and air stop and guide units (4) which prevent or hinder air with bacteria-bearing and other pollutant particles which surrounds the clean air zone (1) from being drawn in between the air supply units and into the clean air zone.

  • Publication number: 20090247065
    Abstract: Provided are methods and devices for improving microvascular function in humans and mammals. Reduction of exposure to airbourne fine particles using air treatment systems increases microvascular function in persons at cardiovascular risk. Preferred treatment systems provide a zone of clean air having >75% reduction in airbourne particle counts around a person at cardiovascular risk. The devices and methods can be optimally used during sleep, when the user is stationary for an extended period.
