Abstract
A sensor may be adapted to reduce motion artifacts by mitigating the effects of the tissue moving within the sensor. A sensor is provided with an elastomeric sensor body adapted to accommodate patient motion. Further, a sensor is provided in which the sensor cable is arranged to mitigate its pressure on a patient's tissue.
Claims24
A sensor comprising:
- an emitter and a detector disposed on a substantially rigid substrate, wherein the substantially rigid substrate is adapted to hold the emitter and detector at a substantially fixed optical distance relative to one another when the sensor is applied to a patient.
A pulse oximetry system comprising:
- a pulse oximetry monitor;
- and
- a pulse oximetry sensor adapted to be operatively coupled to the monitor, the sensor comprising:
- an emitter and a detector disposed on a substantially rigid substrate, wherein the substantially rigid substrate is adapted to hold the emitter and detector at a substantially fixed optical distance relative to one another when the sensor is applied to a patient.
