DEVICE FOR DETERMINATION OF PRIMARY OSTEOMYELITIC FOCUS IN BONE MARROW OF LONG TUBULAR BONES Russian patent published in 1998 - IPC

FIELD: medicine. SUBSTANCE: device has two identical inductive pickups, high-frequency oscillation generator, measuring unit, and recorder. Capacitor is connected in parallel to inductance coil in each pickup. Generator has three outputs. Terminals of two outputs are connected to pickup leads. Measuring unit includes two buffer amplifiers. Inputs of each buffer amplifier are connected to leads of respective pickup, and outputs are connected to two scaling amplifiers. Outputs of scaling amplifiers are connected to first and second input leads of subtractor, respectively, through amplitude selectors. Subtractor output serves as measuring unit output. Recorder is made in form of two pulse counters, inputs of which are connected to measuring unit output, and two digital indicators connected to outputs of each pulse counter. In addition, device is provided with control device of measuring cycle, input of which is connected to third output of generator and outputs, to buffer amplifiers and control inputs of pulse counters. EFFECT: enlarged operational capabilities. 5 dwg
