Abstract
A finger oximeter has a fixed first finger grip member and a second finger grip member that is movable relative to the first fixed finger grip member. The finger grip members are mounted to a casing, with the first finger grip member being fixedly coupled to a top portion of the casing and the second finger grip member being movable vertically within the casing. A force is continuously applied against the movable finger grip member to bias it towards the fixed finger gripping member. This biasing force has sufficient yield so that when a finger is inserted between the two finger grip members, the movable finger grip member would yield to the incoming finger. At the same time the biasing force is of a sufficient magnitude to push the movable finger grip member towards the fixed finger grip member to effect a firm grip of the finger. The biasing force is evenly distributed to the movable finger grip portion to effect a floating finger grip suspension system for the finger oximeter.
