The schemes for using the simplest single-channel device for wireless recording of lung noise on a smartphone and a microcontroller based four-channel device for simultaneous recording of lung noise in different parts of the patient's chest and outside his chest are developed in this paper. Prototypes of such devices, combined with microphones using auxiliary equipment was made. Trial recordings of lung noises and wireless transmission to the smartphone were made. It is shown that the use of byte format of recording with a frequency of 8 kHz is sufficient to provide the required dynamic range for further analysis of the noise. The device is mounted in a lightweight plastic housing that can be attached to the patient's clothing and allows long-term (up to 24 hours) continuous monitoring of respiration. The autonomy of its operation is ensured by the presence of a lithium-ion battery, with the ability to charge from any source of 5V DC, such as from a USB port from a PC or from a charger of a smartphone. The transmission of data of monitoring is wireless using Bluetooth.
Obtained: structural and schematic diagrams of single and multi-channel sensors for electro-auscultation of the lungs with a wireless data transmission channel, which opens up new opportunities for the creation of automated single-channel and multi-channel systems for diagnosing the condition of the lungs. It is concluded that the created single and multi-channel sensors in their technical capabilities fully meet the needs of automated systems for diagnosing the condition of the lungs by acoustic noise.
