AUTOMATED PATIENT'S STUMP ANALYSIS DEVICE Russian patent published in 2022 - IPC A61F2/76 A61B5/107 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to devices for automated analysis of patient’s stump. Device includes a measuring ring. Measuring ring consists of a plate with a central hole accommodating at least eight measuring modules containing a stepper motor, a gearbox consisting of at least three chevron gears, screw-nut transmission, support with radial bearings for screw-nut transmission, at least one contact sensor for creating a positioning system during movement of the measuring rod, a strain gauge for fixing the created forces on the measuring rod, aluminium rod with contact sensor, at least two brass guides for parallel movement of nut and rod, housing fixtures, control adapter of measuring unit, microcontroller, a stepper motor control driver, an analogue-to-digital converter of a strain gauge signal and a base. Base consists of a frame housing, a lower stepper motor, a coupling, a ball-screw gear, an angle piece acting as a connecting part of a measuring ring and a ball-screw gear, two support bearing assemblies, two guides, two contact sensors, a microcontroller, a stepper motor control driver, an on/off button, a stump support, a USB cable for connection to external devices, a power cable and a voltage stabilizer.

EFFECT: more accurate placement of biological tissues and their dynamic movement on 3D model of the article when creating a stump-receiving sleeve for biomechatronic multifunctional upper extremities.
