The pull-off ring is operated by a cable pull that is in direct contact with the pull-off ring for the transmission of sliding force in at least two coupling or engagement points.

Abstract: A medical capsule with a sensor device comprising a light emitting element and a light detecting element with the sensor device being adapted to detect the presence or non-presence of blood and/or Biliverdin based on the light absorption properties of blood and Biliverdin. The capsule is provided with a casing forming a gap at its outer surface. The light emitting element alternatively emits violet light of a wavelength of about 380-450 nm, green light of a wavelength of about 530-580 nm, and red light of a wavelength of about 620-750 nm, whereas the light detecting element generates a separate sensor signal associated with measured light intensities Iviolet, Igreen, and Ired of at least each of the wavelength ranges of the light from the light emitting element. By evaluating a quotient Ired/Igreen, false-positive detection of blood can be avoided. The present disclosure also relates to a calibration method for said medical capsule.
