Publication number: 20230372174Abstract: The present invention relates to an improved device for supplying temperature controlled laminar air flow (TLA) of filtered air to generate a clean air zone, e.g. a controlled personal breathing zone, at a point of care. The specific relative placement of the air inlets and outlets of the device of the present invention enables the provision of a more stable TLA based clean air zone than the prior art devices and at the same time allows for extensive monitoring and reporting features.Type: ApplicationFiled: September 21, 2021Publication date: November 23, 2023Applicant: AIRSONETT ABInventor: Pål Martin SVENSSON

Publication number: 20230321385Abstract: 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..Type: ApplicationFiled: May 30, 2023Publication date: October 12, 2023Applicant: AIRSONETT ABInventors: Dan Allan Robert KRISTENSSON, Pal Martin SVENSSON

Patent number: 8956442Abstract: 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.Type: GrantFiled: April 1, 2009Date of Patent: February 17, 2015Assignee: Airsonett ABInventors: Dan Allan Robert Kristensson, Jan Åke Allen Kristensson, Pål Martin Svensson

Patent number: 8444747Abstract: 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.Type: GrantFiled: October 7, 2010Date of Patent: May 21, 2013Assignee: Airsonett ABInventors: Dan Allan Robert Kristensson, Pål Martin Svensson, Niklas Sondén

Patent number: 8066802Abstract: The present invention relates to a method and a device for providing a zone (2) of clean air at an operation area (3) wherein an air treatment device (1) having a lighting device (25) is brought to a functional position such that the air treatment device (1) and the lighting device (25) are located above an operation area (3) and between the operation area (3) and a ceiling (32) in the operation premises (4). Air is taken into the air treatment device (1) from upper portions of the operation premises (4) and subsequently filtered in the air treatment device (1). The air is cooled in the air treatment device (1) to achieve a lower temperature than impure air (8) surrounding the zone (2) of clean air and subsequently discharged from the air treatment device (1) as a laminar air flow descending slowly downwards towards the operation area (3).Type: GrantFiled: February 26, 2007Date of Patent: November 29, 2011Assignee: Airsonett ABInventors: Dan Kristensson, Jan Kristensson, Pål Svensson

Publication number: 20100120349Abstract: Provided are methods for ventilating a surgical theater using temperature-regulated laminar air flow. Velocity of a downward directed laminar clean air flow is determined by an air-temperature difference between the supply air and room air temperature at the level of the operating table. Room air temperature at the level of the operating table is measured and clean supply air temperature controlled in relation to this measurement. In order to maintain a constant downward directed laminar clean air flow velocity, a constant difference in temperature is maintained between room air temperature at the level of the operating table and the lower temperature of the supply air. In preferred embodiments, this constant temperature difference provides a downward directed air flow velocity of at least 0.25 m/s and is maintained in part by minimizing fluctuations in ambient air-temperature through use of air supply units supplying heated or cooled air outside the clean air zone.Type: ApplicationFiled: October 31, 2009Publication date: May 13, 2010Applicant: AIRSONETT ABInventors: Dan Kristensson, Jan Kristensson, Pål Martin Svensson
