Title:
要求型希釈マスクレギュレータ及びマスクレギュレータにおける補給用酸素の調節方法
Document Type and Number:
Japanese Patent JP4510885
Kind Code:
B2
Abstract:
A demand and dilution mask regulator comprising an oxygen feed circuit and a dilution circuit for supplying air. The oxygen feed circuit and the dilution circuit are connected to a mixing chamber (35). In the dilution circuit, the inhaled breathe-in air flow rate is measured through a capillary duct (43) connected to a Venturi construction (41). A method of regulating the flow rate of additional oxygen uses flow rate data measured through the capillary duct (43) for controlling the oxygen flow rate to be supplied to the mixing chamber (35).
