The invention relates to a mask sealing performance detection device and method. The mask sealing performance detection device comprises an end-expiratory carbon dioxide detector and a detection head cover. The detection head cover is of a cylinder structure with an opening in one end, a containing cavity for containing the head of the human body is formed in the cylinder structure, a tightening device is arranged at the opening of the detection head cover, and the tightening device is used for sealing the opening after the detection head cover is worn on the head of the human body with a mask; the detection head cover is further provided with a mask detection part communicated with the containing cavity, and the end-expiratory carbon dioxide detector is communicated with the mask detection part so as to measure the concentration of end-expiratory carbon dioxide exhaled by the human body and detect the sealing performance of the mask. According to the mask sealing performance detection device, the sealing performance of the mask worn by the protection personnel is detected, so that the sealing performance detection of the mask is more convenient, quicker, more scientific and higher in operability, and the protection safety of the protection personnel is guaranteed.
Description
technical field [0001] The present disclosure relates to the technical field of mask detection, in particular to a mask tightness detection device and method. Background technique [0002] Medical protective masks are the most basic protective equipment that medical staff must use. Protective masks must be worn correctly to ensure a good seal, and only after the inspection is correct can they enter the polluted area. If the tightness test is not done well, the dissemination of aerosol will cause infection of medical staff, and then threaten life. [0003] At present, there are two methods for testing the tightness of medical protective masks: one is self-test: after wearing the protective mask, press the front of the mask with both hands, exhale, and feel positive pressure in the mask; inhale deeply, and feel negative pressure. If the mask fits on the face, it is considered that the mask has a good seal. If there is an air leak, the mask needs to be readjusted and the abov...
