ELECTRONIC SPIROMETER WITH DOUBLE MEASURING METHOD FOR MEASURING THE RESPIRATORY PARAMETERS
The invention relates to an electronic spirometer. According to the invention, the spirometer comprises a turbine (1), provided with magnet blades (2) whose rotation, determined by the flow of the air inspired and expired by a person, is monitored by a Hall sensor (3), after driving the turbine (1)...

Zusammenfassung: | The invention relates to an electronic spirometer. According to the invention, the spirometer comprises a turbine (1), provided with magnet blades (2) whose rotation, determined by the flow of the air inspired and expired by a person, is monitored by a Hall sensor (3), after driving the turbine (1) the air passes through a body with hexagonal tubes (4) playing the role of a pressure reducing element, the pressure difference being measured by a differential sensor (5), the data gathered from the sensors being processed by a microcontroller (6), they being shown on a display (7) and transmitted to a computer by means of a USB interface (12), by means of which there is also carried out the voltage supply of the device.
Invenţia se referă la un spirometru electronic. Spirometrul conform invenţiei este alcătuit dintr-o turbină (1) prevăzută cu palete cu magneţi (2), a cărei rotaţie, determinată de curgerea aerului inspirat şi expirat de o persoană, este monitorizată de un senzor Hall (3); după acţionarea turbinei (1), aerul va trece printr-un corp cu tuburi (4) hexagonale, ce are rol de element reducător de presiune, diferenţa de presiune fiind măsurată de un senzor (5) diferenţial, datele culese de la senzori fiind prelucrate de un microcontroler (6), reprezentate pe un afişaj (7) şi transmise la un calculator, prin intermediul unei interfeţe (12) USB, prin care se realizează şi alimentarea cu tensiune a dispozitivului. |
