Device and method for reducing spread of microorganisms and airborne health hazardous matter and/or for protection from microorganisms and airborne health hazardous matter

摘要

Disclosed is an air distribution control unit or a filtration/ventilation unit which is portable and/or can be mounted on or integrated in furniture e.g. as a cabinet of at the head region of a bed. The filtration/ventilation unit cleanses air from a person/patient by aspirating the person's/patient's exhalation air into the filtration/ventilation unit. To construct an at least partly isolated area around the patient, filtered air can be directed e.g. vertically out of the filtration/ventilation unit to perform an air curtain. Use of the filtration/ventilation unit reduces the risk of dissipation of air-borne diseases and health hazardous matter, and reduces the amount of air to ventilate a room with patients.

主权项

1. A method for partly isolating an area of a bed having a head region, said method comprising:
localising an area which is to be partly isolated, providing at least one filtration/ventilation unit around or in connection to said area, wherein said filtration/ventilation unit is an integrated part of said bed or releasably mounted on said bed, aspirating air from said area into said at least one filtration/ventilation unit, and cleaning said air inside the filtration/ventilation unit, directing cleansed air out of said at least one filtration/ventilation unit in a horizontal to upward direction, thereby forming an air curtain of upwardly flowing air, extending within 20° into or away from the area with respect to vertical extensions of the sides of the bed, thereby partly isolating the area and removing microorganisms or viruses in air from the area.
