FIELD: medical engineering. ^ SUBSTANCE: device has toroidal shell manufactured from dense fabric having elastic flexible filler or husk left after processing grains of cereals. Partition manufactured from dense material is available in the torus lumen. Shell cross-section is circle or ellipse. Smaller ellipse axis on one shell side is 1.5-4.0 times as small as corresponding ellipse axis size in diametrically opposite side. Vibrator is available in the shell. Devices for fixing cushion on seat are mounted on one of shell sides. ^ EFFECT: enhanced effectiveness in redistributing loads caused by sitting body applied to sacrum and ischial tubercles; improved protection against diseases caused by non-uniform load distribution. ^ 4 cl, 4 dwg |
