Tetrahedral environment measuring device and tetrahedral environment measurement method

摘要

PROBLEM TO BE SOLVED: To provide a device and a method for measuring environment inside a mask body, which allow a degree of the leak of particles to be confirmed in real time and allow relationship between the leak of particles and breathing of a wearer to be confirmed.;SOLUTION: The device for measuring environment inside a mask body includes: an inner particle counter for measuring the number of particles inside mask body covering at least a mouth and a nose; an outer particle counter for measuring the number of particles of outside the mask body; a pressure sensor for measuring the pressure inside the mask body; a calculation part for calculating a comparison value between the number of particles inside the mask body and the number of particles outside the mask body using a measuring result of the inner particle counter and of the outer particle counter, and an output part for outputting a comparison value calculated by the calculation part and the pressure measured by the pressure sensor each in a simultaneously displayable manner in association with the time.;COPYRIGHT: (C)2014,JPO&INPIT
