Description

 .one

The invention relates to medicine, in particular to devices for recording respiratory parameters.

The purpose of the invention is to increase the accuracy of recording the parameters of the inert gas.

The drawing shows schematically a device for recording breathing parameters.

The device contains a respiratory mask 1 with a nasal 2 and oral 3 compartments separated by a partition 4, connector 5, isolation valves 6-8 temperature sensor 9, pressure sensor 10, hygrometer 11, gas analyzer sampler 12, thermostat 13 with buffer tank 14 and air conditioning 15, integrator 16, the recorder 17, the thermal insulation casing 18 and the screen 19.

The connector 5 is made in the form of a tube placed in the screen 19. The wall of the tube is made of a material with low thermal conductivity (for example, thermoplastic). At the ends of the connector, breather valves 6 and 7 are installed, which prevent inhalation and vyshokh through the mouth. Inside the connector Z in tanovpeny -Ghermodat.chchik 9, which can be performed, for example, in the form of boron series-connected thermocouples or ter- The pressure sensor 10 is connected with the integrator 16 and the recorder 17J, which can be implemented, for example, in the form of a semiconductor pressure transducer or strain gauge connected to the integrator 16 and the recorder 17, the hygrometer 11 and the sampler gas editor V.

analyzer 12, which are connected to integrator 16 and recorder 17

The nasal compartment 2 of the respiratory mask 1 is connected through a valve 8, a pre-5 rejecting nose through the nose, to an atmospheric air temperature control unit (thermostat 13), which is represented by a buffer tank 14 and an air conditioner 15.

10 Air conditioner 15 provides cleaning of inhaled air: from harmful impurities and stabilization of the set parameters in terms of temperature, humidity and gas composition.

15 The thermostat 13 is placed in a thermally insulating sheath 18 and is provided with a shield that prevents exposure to radiant energy.

The device works as follows.

When you inhale air from the thermostat 13 enters through the nasal compartment 2 of the respiratory mask 1 into the respiratory tract, 25 of the subject.

During exhalation, air from the lungs through the mouth compartment 3 of the respiratory mask 1, valve 6 enters the connector 5, where the characteristics of exhaled air are measured using sensors and sampling of the gas analyzer 12.

The use of stabilization of the parameters of inhaled air (set temperature, humidity and gas composition) JJ eliminates the dependence of these same parameters of exhaled air on the environment. Therefore, the results of studies can be associated only with the functional state of the respiratory system.
