HUMAN BODY SEGMENTS DE-WEIGHTING SYSTEM FOR SIMULATING MICROGRAVITY EFFECTS AND METHOD OF USE THEREOF Russian patent published in 2025 - IPC A61B5/00 G09B23/28 B64G7/00 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medical equipment, namely to a system for weighting human body segments for simulating microgravity effects and a method for using it. System consists of a set of servo motors fixed on a horizontal frame, made with possibility of creating a load with force sensors, ropes, cuffs, a control unit, a controller configured to read values from force sensors of servo drives, convert values to mass and setting the individual load value for each segment of the human body, movement mode buttons, weighing mode, weighting mode on the control unit panel. Shafts of servomotors are equipped with pulleys made with possibility of winding cables, and free ends of cables are made with possibility of attachment to 11 segments of human body. Cuffs are made with possibility of simultaneous attachment to 11 segments of human body with possibility of movement of 11 segments of human body in six degrees of freedom. 11 segments of human body are shin of left leg, shin of right leg, thigh of left leg, hip of the right leg, a belt in the region of the pelvis, a chest in the region of the chest, forearm of the right hand, forearm of the right hand, shoulder of the left hand, head, and the load is equal to the mass of the segment of the human body and has an application vector opposite to the vector of the gravitational field of the earth. In the method, 11 segments of the human body are brought into a horizontal position at the same level with the ground using the mode button. Then verbal command of relaxation is given to the person being tested. Further, the weighing mode button is pressed, the signal from the weighing mode button goes to the controller, the controller reads the values from the force sensors of the servo lines, then the controller sets an individual load value for each of the human body segments. Further, the weighting mode button is pressed, in the controller the calculated weight of each human body segment is converted into electric current supplied to the servo drives to create a load equal to the weight of the human body segment. Load is equal to the mass of the human body segment and has an application vector opposite to the vector of the gravitational field of the earth. Three translational movements along the main axes (X, Y, Z) and three rotational movements around the same axes.

EFFECT: increased degrees of freedom of movement of human body segments during simulation of microgravity, which makes it possible to move the body and its separate segments in six degrees of freedom.
