System for testing quality of respirator and its testing method

Abstract

The testing system includes simulative microbe culture unit, microbe detection unit and microbe sampling unit with function for simulating breath. The sampling unit includes outer tube, filler and container for samples. The filler is flexible connected to top part of the outer tube, and the inner side of the filler is flexible connected to internal fixation board. The low end of the filler is setup inside container. There is an opening in sidewall of the outer tube. The opening is connected to a manual simulation lung. Non-poisonous or lesser poisonous bacteria, fungus or bacteriophage are used as microbiological indicators to simulate stronger poisonous bacteria such as SARS. Ventilation condition of respirator is simulated through manual lung. Thus, the testing system reflects real protecting effect.

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 a mask. Background technique [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 ...

[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
