A patient interface and a method of installing a patient interface for a spectroscopy kit on a patient. The patient interface includes a butterfly-shaped patient interface with a cap on top of the patient interface and in proximity to an optical head.

Patient interface for spectroscopy applications

A spectrophotometric instrument including light signal sources, a detector, a processor/controller, a probe and a calibration device. The light signal sources include a source of measurement light signals having measurement light wavelengths and a source of a calibration light signal at a calibration detection wavelength which is different than the measurement light wavelengths. The probe has one or more send fibers coupled to the measurement and calibration light signal sources for transmitting the measurement light signals and the calibration light signal into tissue, and one or more receive fibers for receiving light including the measurement light signals and the calibration light signal. The calibration device is adapted to receive the probe and has an optical filter for transmitting the measurement light signals but not the calibration light signal. The detector is coupled to the receive fibers to generate electrical signals representative of the light received at the receive fibers. The processor/controller is coupled to the detector and initiates a calibration procedure when the calibration light signal is not detected.
