  • Patent number: 5817008
    Abstract: An optoelectronic pulse oximetry sensor is described which physically conforms to a body portion of a patient, such as a finger, and provides a firm pressing engagement between the sensor and the patient's body portion. The sensor includes a flexible substrate, such as an elastic bandage-type material, which is physically conformable and attachable/adherable to the patient's body portion. The sensor also includes a light source assembly for transilluminating the patient's body portion, and a light detector assembly for measuring transmitted light. The dimensions of the light source and light detector assemblies are constructed to provide a high aspect ratio relative to the flexible substrate. When the sensor is conformably applied to the patient's body portion, localized pressure is exerted on the body portion at the points of contact with the light source and light detector assemblies, thereby stressing the skin and the underlying blood-perfused tissue.

  • Patent number: 5680857
    Abstract: An alignment guide system for use with conventional pulse oximetry monitors connected to transmissive pulse oximetry sensors. The system generates a bar graph or other display showing the magnitude of the optical coupling between the LED's and light detector used in the sensor. By manipulating the position of the sensor while observing the bar graph, medical practitioners can optimize the mount of light from the LED's reaching the light detector. The bar graph also contains an alarm limit marker. If the bar graph falls below the alarm limit marker, the entire bar graph flashes to alert the medical practitioner that the mount of light transmitted to the LED's to the light detector may not be enough to permit sufficiently accurate oxygen saturation measurements.
