  • Patent number: 9138181
    Abstract: Medical sensors configured to provide enhanced patient comfort when worn over a period of time are provided. The medical sensors may include a first padding layer and a second padding layer disposed on either side of an emitter and a detector for measuring a physiological parameter of a patient. The medical sensors may also include an island padding layer secured to a patient-facing side of the second padding layer for reducing localized pressure points that may be caused by protrusions of the sensor. Additionally or alternatively, certain edges of the sensors may be rounded and/or stepped to reduce marking on the patient's tissue and to reduce strain and shear forces produced on the patient's tissue. Still further, certain embodiments provide enhanced light transmission between the emitter and detector of the sensors.
