DEVICE FOR FIXATION OF PARAMETERS OF NASO-ORAL BREATHING BY RECORDING PRESSURE AND TEMPERATURE OF PATIENT'S EXHALED AIR AND TRANSMITTING OBTAINED DATA TO PROGRAM INTERFACE OF SWITCH Russian patent published in 2024 - IPC A61B5/08 

FIELD: medicine.

SUBSTANCE: invention relates to medical equipment, namely to a device for recording nasal-oral breathing parameters by recording patient's expired air pressure and temperature and transmitting the obtained data to a program interface of a switch. Device includes a combined temperature and pressure sensor BMP180 for recording temperature and pressure changes. Device has a microcontroller for primary data processing and transmission of results over a BLE channel for further data processing in a computer in the form of isoline drift removal, Adding the obtained pressure and temperature curves and feeding the processing results to a curve peak detector with an adaptive threshold configured to detect the moments of inhalation and exhalation to calculate the intervals between inhalation and exhalation. Device has a light-emitting diode for indication of operation and level of the device charge, a power button, a voltage converter, a battery and a battery charge control unit, a USB connector. Device is configured to be attached to the virtual reality helmet so that the combined temperature and pressure sensor BMP180 is located under the nasal openings and with the possibility of outputting an error in the absence of one of the indicators of the combined temperature and pressure sensor BMP180.

EFFECT: increased accuracy of readings.
