Important Information
● sensors 5-10 are read by microcontroller 11.
○ preferably provided as a module and are converted into an exact gas flow.
● The invention relates to a device for exact flow measurement of gases independently of
the environmental conditions, such as temperature, humidity, type of gas, oxygen
concentration and ambient pressure. It is intended to make as few compromises as
possible and to be able to measure a large number of very different applications with
high accuracy.
● tubes between sensors are avoided
● Due to a sieve bidirectional flow measurement is possible (also possible with orifice
plates)
● This patent also outlines known methods of measuring the exact gas flow.
Claims
● gas flow channel with sensors and microcontroller arranged as described in patent
● 2 groups of sensors on either side of a measuring resistance arranged in the gas
channel and in the form of a sieve.

FIG. 1 of the accompanying drawings illustrates an inhalation mechanism 1 of a human 2. During
inhalation, the diaphragm in the human body is forcefully lowered (in the direction indicated by the arrow
3) creating a negative pressure in the lungs. At the same time, air enters through the mouth 4 and/or nose
5 to the lungs. The air encounters flow resistance in the oropharynx 6 or the nasopharynx7.
FIG. 4 is a schematic diagram of an apparatus for simulating and monitoring a respiration part of a
humanaccording to one embodiment of the invention;
FIG. 5 is a schematic diagram of a control unit according to one embodiment of the invention;
The present invention relates to an apparatus and method for simulating and monitoring a respiration
pattern of a human.
