Abstract: A process for manufacturing a viscoelastic injection agent having first and second poloxamers and at least one other component, the process including: a) mixing a first injection agent by mixing a the first poloxamer with the second poloxamer and a third amount of the at least one other component to obtain a predetermined amount of the injection agent; b) determining the viscosity of the injection agent obtained in step at different temperatures at a predetermined shear rate to obtain a present viscosity-over-temperature-curve; c) verifying if a maximum viscosity of the present viscosity-over-temperature-curve lays at a predetermined specific temperature range in a predetermined maximum viscosity range depending on the predetermined shear rate; and d) mixing a new injection agent, having amended at least the first amount of the first poloxamer and/or the second amount of the second poloxamer based on determined properties of the first injection agent.

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.
