First Claim
Patent Images
1. An oximeter device comprising:
- a base portion to face a tissue to be measured;
at least one sensor opening formed on a bottom surface of the base portion;
a handle;
a spring, coupled between the base portion and the handle;
a pair of limit stops comprising an upper limit stop and a lower limit stop; and
a stop pin, wherein the stop pin is received between the upper and lower limit stops, the pair of limit stops is fixed relative to one of the handle or base portion, the stop pin is fixed relative to another of the handle or base portion, and the spring urges the upper limit stop and the stop pin apart to create a first gap between the upper limit stop and the stop pin.
