Pulse oximeter that is not affected from motion
A pulse oximeter that is not affected by motion, which is formed of a small disk, a precision spring, a string, a sensor, a motor, a large disk, a rod and a string holder, wherein the oximeter enables continuous tracking of the oxygen saturation of a patient and correct measurement thereof.
1 . A pulse oximeter that mitigates the effects of motion, the pulse oximeter comprising:
a first disk;
a spring connected to said first disk so as to oscillate relative thereto;
a string connected to said first disk and extending along said spring, said string adapted to dampen the oscillation of said spring;
a sensor positioned below said spring, said measure both oxygen saturation and a tensioning force of said spring;
a motor tensioning force of said spring from the sensor, said motor wound to said string and adapted to wind the string so as to set the tensioning force of said spring to a tensioning value;
a second disk having a platform thereon, the platform supporting said motor thereon;
a rod connecting said motor to said string; and
a string holder section receiving said string therein.
2 . The pulse oximeter of claim 1 , wherein said first disk has a diameter smaller than said second disk, said first disk being movable upwardly-and-downwardly relative to the oscillation of said spring.
