    • The present invention relates to a respiratory gas consumption monitoring method and monitoring device that is portable and has high measurement accuracy, for enabling the analysis and prediction of the respiratory behavior of subjects employing a variety of different types of breathing apparatuses in water, etc. Respiratory gas consumption monitoring device (20), for monitoring the respiratory gas consumption of the user of a breathing apparatus (1) in which a respiratory gas (G) inside a high pressure gas container (2) is reduced in pressure at pressure regulator (4) and supplied to a breathing mask (10), is provided with: a primary pressure sensor (21) for detecting the pressure prior to pressure reduction at pressure regulator (4); a temperature sensor (22) for correction; an environmental pressure sensor (23) for detecting the environmental pressure; an amplifier (24) for amplifying the signals from the aforementioned sensors; an A/D converter (25) for performing analog/digital conversion of the amplified signal; a data logger (26) for recording and storing the analog/digital converted signals; and a display (27) for display. In addition, as needed, a computer (X) for calculating, analyzing, and predicting data may be housed in housing (28), and connected to breathing apparatus (1) by connecting primary pressure sensor (21) to a high pressure opening (8) of pressure regulator (4) using a high pressure hose (29).
    • 本发明涉及便携式且具有高测量精度的呼吸气体消耗监测方法和监测装置,用于能够分析和预测在水中使用各种不同类型的呼吸装置的受试者的呼吸行为等。呼吸 气体消耗监测装置(20),用于监测呼吸器(1)的使用者的呼吸气体消耗,其中高压气体容器(2)内的呼吸气体(G)在压力调节器(4) )并提供给呼吸面罩(10),设置有:用于在压力调节器(4)处检测压力降低之前的压力的主压力传感器(21);用于校正的温度传感器(22);环境压力传感器 (23),用于放大来自上述传感器的信号的放大器(24);用于执行模拟/数字对话的A / D转换器(25) 放大信号的离子;用于记录和存储模拟/数字转换信号的数据记录器(26); 和显示器(27)。另外,根据需要,用于计算,分析和预测数据的计算机(X)可以容纳在壳体(28)中,并且通过连接主压力传感器(1)连接到呼吸装置(1) 21)使用高压软管(29)连接到压力调节器(4)的高压开口(8)。
