摘要：
The technical solution relates to the field of medical technology, otorhinolaryngology and can be used for differential diagnosis of edematous-infiltrative and / or exudative form of unilateral or bilateral frontal sinusitis. Device for differential diagnosis of sinusitis memory element comprises two receivers of acoustic oscillations, each of which is connected through the corresponding subblock conversion to the corresponding audio signal sub-block processing logic signal identical with the formation of the first and second measurement channels. Each subblock conversion measuring channel audio signal comprising serially coupled bandpass filter, an amplifier, a rectifier and ADC, and a signal processing logic subunit contains two comparators, two elements OR INHIBIT element and has three inputs and three outputs. The output of each ADC converting the audio signal sub-block is connected to the first input of the logic subblocks corresponding signal processing, which is the first input of the combined first and second digital comparators corresponding subblock logic signals processing. The second input of each sub-block is a logical signal processing a second digital input of the first comparator, while the second inputs are combined and connected to the first output of the storage element. The third input of each logical sub-block signal processing is the second input of the second digital comparator, wherein the third inputs are combined and connected to the second output of the storage element. The first output of each subblock logic output signal processing is less than the first digital comparator, the outputs of which are equal and greater are connected to inputs of the first OR gate whose output is connected to an information input element BAN. Each subblock logic processing signal outputs are equal and greater second digital comparator connected to the inputs of the second OR gate whose output is connected to the INHIBIT input prohibiting element, whose outpu
