Abstract

The invention discloses a bilateral nasal resistance and nasal flow testing device and method. Two ends of a differential pressure sensor I are separately connected with a ventilation pressure measuring opening I and a ventilation pressure measuring opening II; two ends of a differential pressure sensor II are separately connected with a ventilation pressure measuring opening III and a ventilationpressure measuring opening IV; a data processing device is electrically connected with the differential pressure sensor I, the differential pressure sensor II and a differential pressure sensor III;a breathing flow sensor I is arranged between the ventilation pressure measuring opening I and the ventilation pressure measuring opening II; a breathing flow sensor II is arranged between the ventilation pressure measuring opening III and the ventilation pressure measuring opening IV; the breathing flow sensor I and the breathing flow sensor II separately communicate with the other end of a breather pipe I and the other end of a breather pipe II; and an air pipe valve I and an air pipe valve II are separately arranged on the rear side of the breathing flow sensor I and the rear side of the breathing flow sensor II. The device is convenient and sanitary; the operation is simple, and the influence of a traditional detection ventilation pipeline on a test result is reduced; bilateral nasal cavity resistance and nasal flow can be detected at the same time.

Description

Technical field [0001] The invention relates to the technical field of medical equipment, in particular to a device and method for testing bilateral nasal resistance and nasal flow. Background technique [0002] Nose measurement is a method of detecting flow resistance in the nose. With rhinometry, when inhaling and exhaling, the pressure drop in each nostril and the associated nasal cavity (upper pharynx) is measured. These tests can be active or passive. In order to determine the atomization resistance of the nostril with the relevant nasal cavity, it is necessary to determine the pressure difference generated from the nostril opening to the upper edge of the nose (nasal septum) at the same time as the corresponding air flow when inhaling or exhaling. [0003] Since the application of nasal resistance detection technology in the last century, the diagnosis of nasal diseases has mainly relied on manual inspection and analysis and nasal endoscopy. These inspections are complicate...
