Embodiment Construction

[0018] The device according to the invention consists at least of a basic unit 12 with the transmitter electronics 15 and receiver electronics 16 required for the measurement purposes and the implementation part 1 which comes into direct contact with the nasal tissue during the measurement.

[0019] The implementation part 1 is shown at a and b in FIG. 1 . It consists of a stirrup-shaped base, the two sides of which can be affixed to the nose wing in a reasonable shape. On one side of the embodiment part 1 , a light-emitting element, the optical-emitting element 2 , is arranged, and on the opposite side, a light-receiving element, the optical-receiving element 3 . They are constructed either as discrete radiation sources and detectors with their optical axes positioned in the direction of the tissue ( FIG. 2 a ), connected to the base unit 12 via electrical lines 4 or as optical connections enabling light transmission from and to the base unit 12 6, 7, the optical connection ...

Abstract

The invention relates to the field of the construction of device and relates more particularly to a method and a system which can for example be used to measure a nasal obstruction. The aim of the invention is to provide a method and a system which allows to measure the swelling of the nose. This aim is attained by a system that comprises a basic device (12) with light-producing components (13) and light-detecting components (14) and emitter and receiver elements (2, 3) that are disposed outside said basic device (12) on an application element (1). The aim is furthermore attained by a method according to which light is emitted from an optical emitter element (2). An optical receiver element (3) captures the light emerging in the area of emergence of the light from the side of the nose and records the incoming values and calculates therefrom diagnostically utilizable parameters.

Description

technical field [0001] The present invention relates to the fields of medicine and device manufacture, and also to a device for optical measurement of nasal swelling, which can be used, for example, to measure nasal congestion from allergic provocation. Background technique [0002] From a medical point of view, there is a demand for objectification of the measurement of the swelling state and swelling changes in eg allergic reactions caused, for example, at the time of nasal provocation examination. [0003] Allergic rhinitis is currently diagnosed by raising the symptomatic response zone (stimulating sneezing, secretions, eg tears away from the symptoms) and by measuring nasal congestion after the allergic stimulus by means of nasal manometry (Clement et al.; "Rhinomanometry-a review", OPLJ Otorhinolaryngol. Relat. Spec. 46, 173-91, 1984). The disadvantage of nasal pressure measurement in this context is that it cannot be measured during allergy practice. If the nasal co...
