Device for measuring energy expenditure of a person working in a breathing apparatus

摘要

Device (1) for measuring the energy expenditure of a person working in an airway protection apparatus incorporating an exhaust valve face mask (4),at least one cylinder (5) with compressed air coupled with a first-stage pressure reducer (6),which is connected to a flexible tube tube tube (7) with an automatic breathing machine (8) reducing the air pressure in the tube tube (7) to the pressure suitable for breathing by man and leading the air to the face mask, with the bottle (5) with compressed air attached to the carrier (9)which is used to attach it to a person, is characterized by the fact that in the respiratory protection apparatus, between the face mask,and the breathing machine (8) is fitted with a flow meter which is connected by an electrical cable (12) to a processing system located in the housing (3),which processes the flow of air inhaled by the person being measured into energy expenditure.
