Problems solved by technology

The statement also clearly stated that due to the relatively short life of electrochemical components and no literature reports on their long-term stability, the accuracy of the instrument needs to be evaluated regularly, and the method and frequency of calibration must be determined
[0006] It is known that breath analyzer products are calibrated by regular standard cylinder gas calibration. However, in actual use, the transportation and use of standard cylinders is very inconvenient, and the detection range of breath analyzer instruments is usually low. The calibration concentration is also very low. For example, the calibration of NO analyzer uses NO gas with a concentration of 50-75ppb

Abstract

The invention provides a quality inspection system of an expiration analyzer, which is used for detecting the sampling quality and the analysis quality of an expiration analyzer. The quality inspection system comprises an automatic air distribution unit, an expiration sampling quality inspection unit, an expiration analysis quality inspection unit and a master control unit, wherein the automatic air distribution unit is used for generating a simulated exhaled gas with settable gas components, the concentration, the temperature, the humidity and the flow; the expiration sampling quality inspection unit can be connected with an expiration analyzer to be inspected to detect the temperature, the humidity, the flow, the pressure and the time of the distributed gas passing by the expiration analyzer; the expiration analysis quality inspection unit is used for detecting the gas concentration result of the distributed gas detected by the expiration analyzer for analysis and determination; andthe master control unit comprises a control module, a GPRS-4G communication module, a data storage module, a screen and a visual operation interface, and can complete automatic gas distribution and expiration sampling analysis quality detection according to input requirements, thereby achieving quality inspection of the expiration analyzer.

Description

technical field [0001] The invention relates to a quality inspection system of a breath analyzer. Background technique [0002] With the development of science and technology, molecular diagnosis based on breath markers and related scientific and technological achievements have won five Nobel Prizes in Biomedicine and Chemistry, and won one of the top 10 contemporary medical innovation awards at the World Medical Summit held in the United States in 2011 . Breath testing began to be promoted in 2010, and various breath analyzers came into being. By detecting various gas molecular components and concentrations in known human exhaled gas, it can assist doctors in diagnosing patients' diseases, monitoring disease states and observing The therapeutic effect is non-invasive, safe, accurate and reliable, and the social and economic benefits are remarkable. [0003] At present, there are many types of breath analyzers on the market, and they are mainly applied in two fields, one i...
