FIELD: medicine; applicable in determination of osteomyelitis focus and its boundaries in bone marrow of long tubular bones. SUBSTANCE: device for determination of primary osteomyelitis focus in bone marrow of long tubular bones has two identical inductive pickups, generator, measuring unit and monitor. In each pickup, connected parallel to induction coil is capacitor. Generator has two outputs whose terminals are connected with outputs of pickups. Measuring unit has two buffer amplifiers whose inputs are connected with outputs of respective pickups and outputs are connected to two scalers. Output of scalers via amplitude selectors are connected with the first and second input lead of subtracter. Output of subtracter is output of measuring unit. Monitor is made in form of two pulse counters whose inputs are connected to output of measuring unit and two digital indicator indicators connected to output of each pulse counter. Besides, introduced into measuring unit is control device of measurement cycle connected with generator, buffer amplifiers and pulse counters. EFFECT: extended service capabilities and high efficiency. |
