Nose mask for use with respirator, has thermopile for collecting airflow caused by mouth respiration

摘要

The nose mask (9) has a respirator hose connector (8) and a thermopile (10) for collecting airflow caused by mouth respiration. The thermopile converts the airflow caused by mouth respiration into electrical signal which is then sent through an electrical cord (13) arranged with the respirator hose connector. The thermopile also measures temperature difference between breathing temperature and ambient temperature caused by mouth respiration. The nose mask is connected to a compressed air source (3) through a respirator hose (7). A control unit (6) is provided to control the flow of compressed air from the compressed air source. Independent claims are included for the following: (A) Respirator including the nose mask; (B) Control device of respirator; and (C) Respirator control method.
