Embodiment Construction

[0024] The present invention will be described more fully hereinafter with reference to the accompanying drawings. Like numbers refer to like elements throughout.

[0025] a) will now refer to figure 1 A respiratory function test system including a respiratory function test device according to an embodiment of the present invention is explained. This respiratory function testing system 1, as described later, is configured to test the subject's respiratory function based on the data of the inspiratory volume when the subject breathes and (according to the intrapleural pressure estimation method) the data of the intrapleural pressure obtained from the pulse wave. respiratory function.

[0026] Such as figure 1 As shown, the respiratory function testing system 1 includes a flow sensor 3 configured to detect the airflow rate (inhalation flow) when the subject inhales, a pulse wave sensor 5 configured to detect the pulse wave of the subject, and configured to be based on the flo...

Abstract

A respiratory function testing apparatus capable of testing a respiratory function of a subject more accurately. In the apparatus, a respiratory state detection unit acquires a first signal representative of different inspiratory volumes corresponding to a plurality of breaths of the subject and a second signal representative of intrapleural pressures corresponding to the respective different inspiratory volumes, and detects a plurality of respiratory states corresponding to the different inspiratory volumes and their corresponding intrapleural pressures. A respiratory state determination unit captures a state of the respiratory function of the subject on the basis of the plurality of respiratory states corresponding to the different inspiratory volumes and their corresponding-respective intrapleural pressures.

Description

technical field [0001] The present invention relates to techniques for testing respiratory function, such as lung compliance, of a subject. Background technique [0002] In recent years, lung diseases such as pneumonia, chronic obstructive pulmonary disease (COPD) and the like are gradually increasing all over the world. Lung strain, which indicates the flexibility of the lung, is known to be a useful indicator for screening and / or determining the efficacy of treatments for lung diseases. In order to measure this lung strain, the intrapleural pressure needs to be measured. However, it is difficult to measure intrapleural pressure. Esophageal pressure can be measured instead of this intrapleural pressure. However, in order to measure esophageal pressure, a balloon catheter needs to be inserted into the esophagus, which may cause great discomfort to the patient. Therefore, measurement of lung strain cannot be performed comfortably. [0003] In order to overcome such disad...
