Abstract
Official abstract text for this publication.
A reflection-detector sensor position indicator comprises emitters that transmit light having a plurality of wavelengths. A detector outputs a sensor signal. At least one reflection detector outputs at least one sensor position signal. An attachment assembly attaches the emitters, the detector and the reflection detector onto a tissue site. A sensor-on condition indicates that the attachment assembly has positioned the emitters generally centered over a fingernail, the detector on a fingertip opposite the fingernail and the reflection detector over the fingernail. The sensor signal, in the sensor-on condition, is at least substantially responsive to the emitter transmitted light after attenuation by pulsatile blood flow perfused within a fingernail bed underneath the fingernail. The sensor position signal, in the sensor-on condition, is at least substantially responsive to the emitter transmitted light after reflection off of the fingernail.
First claim
Opening claim text (preview).
What is claimed is: 1. A physiological measurement system comprising: a sensor having an attachment assembly configured to position emitters over a fingernail and to position a detector on a fingertip opposite the fingernail so that the emitters are positioned to transmit multiple wavelength light into the fingernail and so that the detector is positioned to detect the transmitted light after attenuation by pulsatile blood flow perfused within a fingernail bed underneath the finge…
