DIFFERENTIAL DIAGNOSTIC METER OF DISORDERS IN HUMAN SOFT TISSUES Russian patent published in 2019 - IPC A61B5/103 

FIELD: medicine.

SUBSTANCE: invention relates to medical equipment. Differential diagnostic softness meter of soft tissues from symmetrical sides of human spinal column comprises probe (1). Probe is rigidly connected with elastic beam (2). Beam is sensitive element and is connected with deformation force indicator (14). Deformation force indicator is rigidly fitted in case (7). Probe passes inside cylindrical part of housing. Device has an element limiting penetration of the probe into human tissue. Meter is additionally equipped with second sensitive element. Sensitive elements are made in the form of elastic tensometric beams with glued strain gauges (3, 4, 5, 6). Resistive strain gauges are combined into bridge circuit (10) and are powered from an additionally introduced DC power supply (11). Output of bridge circuit is connected to input of instrument amplifier (12) connected to input of controller (13) with indicator (14). Instrumentation amplifier normalises differential signal generated by two beams. This signal is presented on the display and is an output signal on human soft tissue disorders.

EFFECT: higher accuracy of the processed difference signal and faster operation.
