Abstract

The invention discloses a basal metabolism measuring device. The basal metabolism measuring device comprises a housing (1), a control device (2), an oxygen concentration measuring device (3), a carbondioxide concentration measuring device (4), a flow measuring device (5) and a collecting pipeline (6), wherein the oxygen concentration measuring device (3), the carbon dioxide concentration measuring device (4), the flow measuring device (5) and the collecting pipeline (6) are connected with the control device (2); the flow measuring device (5) is arranged at an air inlet of the measuring deviceand connected with the collecting pipeline (6); the air outlet end of the collecting pipeline (6) is connected with the air inlet end of the oxygen concentration measuring device (3); the air outletend of the oxygen concentration measuring device (3) is connected with the air inlet end of the carbon dioxide concentration measuring device (4); and the air outlet end of the carbon dioxide concentration measuring device (4) is connected with the backflow end of the collecting pipeline. The flow speed, the carbon dioxide concentration and the oxygen concentration of exhaled air of a human body can be measured in real time, and the respiratory quotient and the metabolic rate can be calculated according to the weight and the height of the human body. The basal metabolism measuring device is small, exquisite, quite convenient to carry and easy to operate.

Description

technical field [0001] The invention relates to the field of energy metabolism measurement, in particular to a basic metabolism measurement device. Background technique [0002] For the determination of basal metabolism, it is usually determined by measuring energy metabolism. The method of energy metabolism determination usually adopts an indirect measurement method. The principle of the indirect measurement method has a strict compliance relationship according to the relationship between energy metabolism and gas metabolism, so it can be passed Gas metabolism was measured to extrapolate energy metabolism. Early gas metabolism tests were relatively simple, generally using the Douglas air bag method. During the test, all the exhaled gas is collected in the air bag, and dozens of air bags are required for the whole test process. After the test is completed, first measure the volume of the exhaled gas, and then use chemical methods to analyze the concentration of oxygen and ...
