The invention pertains to medicine, namely to medical technology, and can be used in various fields of medicine for non-invasive (percutaneous) and intraoperative (surgical) identification of the parameters indicating blood flow and oxygen saturation of blood. The objective of the present invention is to create a method and device for real-time estimation of blood flow, tissue microcirculation and oxygen saturation of blood for control and correction of pharmacological, physiotherapeutic and surgical treatment. In terms of method, the said objective is achieved by identifying the qualitative and quantitative parameters of blood flow from the microcirculation volume of tissue in the point of sensing with ultrasonic Doppler indicators of blood flow at a continuous radiation mode with a frequency of more than 20 MHz, by using the software electronic "Micro" unit functioning at a maximum amplification, with the simultaneous estimation of oxygen saturation of blood by using the pulse oximeter sensor which is affixed to the sensing area, and the tissue microcirculation and regional blood circulation are assessed on the basis of the obtained figures indicating the oxygen saturation of blood and the blood flow parameters in a single vessel and in a microcirculation volume of tissue for subsequent diagnosis, screening control and correction of the pharmacological, physiotherapeutic and surgical treatment, in real time mode. The said objective in the device is achieved through introduction of the pulse oximeter unit, software electronic "Micro" unit, control and visualization units, whereas the quantity, shape and frequency of acoustic heads is selected depending on the anatomic features of the subject under analysis: surgical, transcutaneous, laparoscopic, with a frequency of 10, 20, 25, 30 MHz, elongated, L-shaped； therewith the ultrasonic Doppler indicator is equipped with a titanium case to enable multiple sterilization.
