  • Patent number: 5267941
    Abstract: A microfilter (4) for fitting into a filter-box of an infants incubator comprises a pad (22) of non-woven filtering material enclosed in an envelope (21) of water-repellent cohesive and non-woven material which is highly permeable to air and oxygen. The envelope prevents the escape of fibrous particles from the pad and has one side colored differently from the other to reduce the risk of being replaced back-to-front in the filterbox. The envelope may be placed in a similar envelope. It may also have one face of multilayer construction with the layers individually removable so that they can be discarded when dirty.
    Type: Grant
