Abstract
A replaceable sensing module is provided for use in a pulse oximetry device, allowing for quick replacement of a failed sensor element. A fingertip pad and a fingertip cover form the sensing module and cooperate to form a receptacle into which a patient'"'"'s fingertip can be inserted. The sensing module has an internal spring, thereby permitting the module to be inserted into various oximetry type devices. The module has mounting rails and a multi-pin electrical connector, allowing a user to quickly replace the module in the event of component failure.
