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 pro

Embodiment Construction

[0027] The present invention will be further described below in conjunction with accompanying drawing:

[0028] A mask quality detection system, comprising a simulated microorganism culture device, a microorganism detection device, it also includes a breathing simulation microorganism sampling device, the breathing simulation microorganism sampling device includes an outer sleeve 1, the top of the outer sleeve 1 is movably connected to a funnel 2, and the funnel 2. The inner side of the upper end is movably connected with the internal fixation plate 3. The lower end of the funnel 2 is set in the sampling container 4. The side wall of the outer sleeve 1 is provided with a side wall opening 5, and the side wall opening 5 is connected with the artificial simulated lung 6.

[0029] The volume of the artificial simulated lung 6 is preferably 0.1-5L.

[0030] The artificial simulated lung 6 is preferably cylindrical, and a piston 7 is arranged inside. The piston 7 is connected to a ...

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 ...
