Abstract

The invention discloses a nasal resistance measuring instrument controlled by double CPUs, and relates to the technical field of medical equipment. The system comprises a human nasal cavity respiration detection system and a central data processing system, wherein the human nasal cavity respiration detection system is communicated with the central data processing system in a UART mode; a data collecting and processing unit in the human nasal cavity respiration detection system is a Cortex-M3 processor and is used for detecting and collecting bilateral nasal flow data, pressure data and travel switch gear switching data during nasal cavity respiration; and a central data processing unit of the central data processing system is a Cortex-M4 processor and is used for receiving and processing data uploaded by the Cortex-M3 processor through a UART and displaying a test process and a test result to a result display unit in real time. Double-CPU control detection is adopted, the measurement result is more accurate, and a transmission system is more stable.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a measuring instrument for testing nasal resistance, in particular to a nasal resistance testing instrument controlled by dual CPUs. Background technique [0002] At present, most of the preoperative evaluation of nasal resistance of patients relies on the clinical experience of rhinologists, and lacks objective basis. The understanding of nasal diseases by rhinoscopy, endoscopy, laryngoscopy and imaging examinations is mainly reflected in the aspect of morphological observation. The ventilation function of the nasal cavity is rarely evaluated. On the other hand, the cost of rhinoscopy, endoscopy, laryngoscopy and imaging examinations is relatively high, and the radiation is large. Patients and their families have scruples to a certain extent, which is economically unaffordable and difficult. Effectively and objectively reflect the degree and nature of the patient's nas...
