METHOD AND DEVICE FOR DETERMINING PRIMARY OSTEOMYELITIS FOCUS IN LONG TUBULAR BONE MARROW Russian patent published in 1999 - IPC

FIELD: medicine. SUBSTANCE: method involves setting transducers and evaluating parameters of the healthy and injured. Inductance coils are used as transducers. Quality factor changes are determined. Focus presence is determined from increased dielectric losses in injured extremity. Two metal electrodes are additionally used as transducers that are set on the focus boundary on the injured extremity. Oscillation circuit quality factor is measured. The electrodes are attached to oscillation circuit capacitor. The electrodes are placed on the symmetric healthy extremity areas. Quality factor is determined once more. Oscillation circuit quality factor changes are evaluated. Oscillation circuit quality factor being increased when electrodes are placed on the injured extremity, a focus is considered to be localized. Device has unit for positioning and examining a patient having transducers fixed and measuring unit. The transducers are two separate inductance coils. The measuring unit has two metal electrodes and two fixed capacitors. One of electrodes is connected to common bus of the measuring unit through the first capacitor. The second electrode is connected to potential terminal of recorder unit through the second capacitor. EFFECT: enhanced reliability of diagnosis. 2 cl, 3 dwg
