Zusammenfassung: | The invention relates to an electronic device for continuously monitoring the breathing frequency, with application in the medical field, mainly for diagnosing sleep apnea syndrome. According to the invention, the device comprises a linear Hall sensor (2) placed on the thoracic cage of a patient, which surveys a magnetic field created by a permanent magnet (1) placed in its proximity and transforms the modification of the magnetic field intensity into a PWM signal acquired by a microcontroller (3) which transmits the data, by means of an emitter-receiver module, to a personal computer and a DC-DC converter (5) which generates the voltage necessary to the device, by some batteries (4).
Invenţia se referă la un dispozitiv electronic, pentru monitorizarea continuă a frecvenţei respiratorii, cu aplicaţii în domeniul medical, în principal, pentru diagnosticarea sindromului de apnee în somn. Dispozitivul conform invenţiei este constituit dintr-un senzor (2) Hall liniar, plasat pe cutia toracică a unui pacient, care monitorizează un câmp magnetic creat de un magnet (1) permanent, amplasat în vecinătatea acestuia, şi transformă modificarea intensităţii câmpului magnetic într-un semnal PWM, achiziţionat de un microcontroler (3) ce transmite datele, prin intermediul unui modul emiţător-receptor, spre un calculator personal, şi un convertor DC/DC (5) care produce tensiunea necesară dispozitivului, de la nişte baterii (4). |
