Abstract

The invention provides a lung function instrument and a method capable of measuring the flow and the content of respiratory gases synchronously. The device comprises a double function sensor unit, aninternal signal transmission unit, a data processing unit and software unit, a data storage unit, a user interface unit, a printing unit, an external signal transmission unit and a power unit. The method comprises the steps of measuring a forward flow propagation time Tf and a reverse flow propagation time Tb and collecting real-time infrared radiation intensity signals by using the double function sensor unit, calculating the flow and the content C of the real-time carbon dioxide of respiratory gases by using the data processing unit and software unit, and displaying the same on a user interface in real time graphically and outputting a test report. The method measures the ventilation function and the gas exchange function of lung functions synchronously in the same integrated sensor, sothat the diagnosis efficiency is greatly increased and the application of wireless data transmission in telemedicine is realized.

Description

technical field [0001] The invention relates to the field of respiratory gas flow and component measurement, in particular to a lung function instrument and method for synchronously measuring the flow and content of respiratory gas. Background technique [0002] Pulmonary function tests include ventilation function, ventilation function, respiratory regulation function and pulmonary circulation function. Respiratory flow measurement is widely used in the field of lung function testing. Basic pulmonary function test is a physical examination method. Some basic pulmonary function parameters such as volume indicators, ventilation indicators, airway resistance and other ventilation function indicators can be obtained through simple respiratory flow measurement. Can screen common chronic lung diseases such as: emphysema, asthma, chronic obstructive pulmonary disease. This measurement only checks the ventilatory function. [0003] Most of the flow measurement of spirometers are...
