Abstract

Der Nasenfilter ist dazu bestimmt, Personen, die verstärkt unter Allergien leiden, vor dem Einfluß des Pollenfluges, der Staubmilben oder Mikrosporen zu schützen. Denkbar ist sein Einsatz auch in Bereichen der Medizin oder Industrie (Chipherstellung).
Die Filtergehäuse sind ergonomisch auf thermischem Wege weitgehendst den individuellen Gegebenheiten von Nasengang und Nasenscheidewand angepaßt und besitzen am oberen oder unteren Ende eine ovale Öffnung mit nach innen gerichtetem umlaufenden Rand, der eine aus Vlies bestehende Filterscheibe aufnimmt. Die Struktur der Filterscheibe erlaubt es (gesplittete Filterfasern, die von Deckvlies umhüllt sind) die "Raumwirkung" des Nasenfilters zu erhöhen, wodurch die Aufnahmefähigkeit verbessert und die Nutzungsdauer verlängert wird.
Die Filtergehäuse werden untereinander mit einem halbkreisförmigen Steg fest verbunden und besitzen zur Unterstützung des Paßsitzes lamellenförmige Einschnitte oder konzentrisch angeordnete Riffelungen an ihrer Oberfläche.
Die Filtergehäuse können entweder separat oder als Filtereinheit mit Steg auf dem Weg des Tiefziehens bzw. Spritzgießens hergestellt werden, wobei die Filterscheiben sofort oder später eingebracht werden.

Figure 00000001
The nasal filter is designed to protect people who suffer from allergies from the influence of pollen, dust mites or microspores. Its use is also conceivable in the fields of medicine or industry (chip manufacture).
The filter housings are ergonomically thermally largely adapted to the individual circumstances of the nasal passage and nasal septum and have an oval opening at the upper or lower end with an inward circumferential edge that receives a filter disc made of fleece. The structure of the filter disc (split filter fibers, which are covered with cover fleece) allows the "spatial effect" of the nasal filter to be increased, which improves the absorption capacity and extends the service life.
The filter housings are firmly connected to each other with a semicircular web and have lamellar incisions or concentrically arranged corrugations on their surface to support the snug fit.
The filter housings can either be manufactured separately or as a filter unit with a web on the way of deep drawing or injection molding, the filter disks being inserted immediately or later.
