System for testing quality of respirator and its testing method

Abstract

The invention discloses a mask quality detection system and a detection method thereof. The detection system includes a simulated microorganism cultivation device and a microorganism detection device, and also includes a breathing simulation microorganism sampling device, and the breathing simulation microorganism sampling device includes an outer sleeve and an outer sleeve The top is movably connected with the funnel, the inner side of the upper end of the funnel is movably connected with the internal fixation plate, the lower end of the funnel is set in the sample container, and the side wall of the outer casing is provided with a side wall opening, which is connected with the artificial simulated lung. The advantages of this system are: Use non-toxic or less toxic bacteria or fungi or phages as indicator microorganisms to simulate clinically toxic pathogenic microorganisms such as lambda phages to simulate Sars virus, etc.; use artificial simulated lungs to simulate the breathing of masks used by humans Ventilation status, test the quality of the mask, and truly reflect the protective effect of protective equipment.

Description

Technical field [0001] The invention relates to a detection system and a detection method for the quality of medical protective articles, in particular to a detection system and a detection method for the quality of masks. Background technique [0002] At present, many pathogenic microorganisms pose a serious hazard to the human body. In order to prevent the infection of the human body by pathogenic microorganisms, medical staff must wear protection when diagnosing and treating infected patients, or when the general population prevents infectious diseases of the respiratory system. Wear protective clothing and protective masks, but what kind of protective masks can block pathogenic microorganisms and protect medical staff or healthy people from being infected? At present, there are no devices and methods for directly detecting the quality of masks for preventing pathogenic microorganisms. The existing quality standards for protective clothing (GB1908...

Problems solved by technology

[0002] At present, many pathogenic microorganisms pose serious harm to the human body. In order to prevent the infection of the human body by pathogenic microorganisms, medical personnel must wear protective clothing when diagnosing and treating infected patients, or when the general population prevents respiratory infectious diseases. However, what kind of protective mask can block pathogenic microorganisms and protect medical staff or healthy people from infection? At present, there is no device and method for directly detecting the quality of masks against pathogenic microorganisms, and the existing quality standards for protective clothing (GB19082-2003[1], GB19083-2003[2]) do not have a suitable method to identify Whether protective equipment such as masks can effectively block pathogenic microorganisms such as Sars virus
