Compression Mechanism
The Drive Belt, driven by the electrical Motor, drives the Carry Ball Screw forcing the Carry Ball Nut up and down.
The Carry Ball Nut is fitted to a piston that moves the suction cup piston up and down.
The Decompression Spring reduces the upstroke force.
The Suction Cup is adjusted to the patients’ chest with a servo aid system. The suction cup can easily be replaced
with respect to hygiene.
