The invention relates to the field of medicine, to physiotherapy, in particluar to technical means of information medicine for irradiation of patients with the physical field of force and can be used for the therapeutic influence on a patient or certain parts of his(her) body when treating non-malignant neoplasms and precancer diseases. The invention is based on the task to develop a diagnostic and therapeutic complex allowing to enhance the treatment efficiency basing on automatic regulation by the frequency and duration of the infraacoustic wave exposure of a patient' s pathogenic organ and also basing on achievement of the more accurate determination of the duration and number of infraacoustic wave exposure sessions of a pathogenic region of a patient' s body basing on the use of bioresonance diagnostics methods and equipment. Clinical and experimental studies found that significant enhancement of treatment efficiency was achieved by performing therapeutic procedures with exposure of a patient' s pathogenic organ to infraacoustic wave energy with automatic change of the output frequency every 10 s in the range from 16.3 to 17.3 Hz so that the frequency value should increase and decrease successively between 16.3 and 17.3 Hz with frequency discrete pitch size of 0.1 Hz. In contrast to known infraacoustic irradiators, the claimed diagnostic and therapeutic complex allows to calculate with high accuracy the optimum duration of infraacousic wave exposure of a patient' s body pathogenic region, assess rapidly the treatment over time taking into account the individual peculiarities of each patient due to automatic regulation of the frequency and duration of the infraacoustic wave exposure at each frequency and also the complex use of the information about the condition of the organism and pathogenic organ of a patient with the help of the bioresonance testing method with determining the entropy coefficient reflecting a patient' s pathogenic organ condition. The technical result achieved by the invention consists in significant enhancement of the treatment efficiency in case of automatic regulation by the frequency and duration of the infraacoustic wave exposure of a patient' s body pathogenic region at each frequency in the prescribed range with rapid assessment of therapeutic factors during the treatment course.
