Breathing warm-body dummy for detecting inhalation exposure of particulate pollutants and operation method thereof

Abstract

The invention discloses a breathing warm-body dummy for detecting inhalation exposure of particulate pollutants and an operation method thereof. The breathing warm-body dummy comprises a dummy body, atemperature control device, a breathing simulation device and a plurality of particulate matter detection devices. A temperature control device is arrange on that dummy body; The respiratory simulation device comprises a 3D printing respiratory tract and an artificial lung; 3D prin respiratory tract is arranged inside that dummy body, the simulate lung is arranged outside the dummy body, and is connected with the respiratory tract through a gas delivery skin pipe; Several particulate matter detection devices are mounted in the bottom volume of the 3D printing respiratory tract of the respiratory simulation device and in the environment at the mouth and nose of the dummy body and 1 meter away from the dummy body, respectively. The invention can simulate the heating temperature of the surface and the interior of the human body, and can largely restore the micro environment of the human body under the real situation. It can also simulate the respiratory characteristics of human body. Itcan be used to simulate the concentration of particulate pollutants in respiratory tract and respiratory microenvironment.

Description

Technical field [0001] The invention belongs to the technical field of a breathing warm body dummy, and particularly relates to a breathing warm body dummy used for detection of human body inhalation exposure of particulate pollutants and an operation method thereof. Background technique [0002] Thermal dummy refers to an instrument with a human body shape that can simulate the heat dissipation of the human body. It is mainly used in places such as the evaluation of indoor environmental comfort and the test of thermal resistance of clothing. Using a thermal manikin instead of a real person for experimental research can objectively and systematically evaluate the thermal environment and predict the physiological response of the human body to the thermal environment. Moreover, in some relatively harsh and dangerous experimental environment conditions, the use of real people for experiments has a higher risk factor, and personal safety cannot be guaranteed, so it is necessary to us...

AI Technical Summary

Problems solved by technology

The existing thermal manikins generally only simulate the temperature of the human body, and do not involve the simulation of human respiratory characteristics. In view of the current serious environmental pollution problems, the thermal mannequins should be applied to the detection of indoor environmental quality to complete the environmental Human inhalation exposure assessment of pollutants requires urgent development of respiratory thermal manikin
