Abstract: Disclosed is a fully implantable sensor for detecting at least one analyte in a sample of body fluid. The sensor has a measurement chamber plate that receives the sample of bodily fluid and a quantum cascade laser illumination source that generates an illumination light beam in the spectral range and transmits it to the measurement chamber plate. The illumination light beam at least partially illuminates the measurement chamber plate and the measurement chamber plate generates a reflection light beam in response to the illumination by the illumination light beam. The reflection light beam at least partially illuminates the sample of body fluid within the measurement chamber plate. An optical detector detects at least one property of the reflection light beam and generates a sensor signal dependent on the presence of the analyte. A controlled evaluates the sensor signal. A method using an inventive fully implantable sensor is also disclosed.

Abstract: A cannula cartridge for receiving a cannula includes a needle assembly, a cannula and a protector. The needle assembly is movable within the protector between first and second positions. In the first position the needle is covered by the protector and a retainer of the protector engages an engagement element of the needle hub by a form fit connection. In the second position the needle at least partially extends from the protector. An inserter can move the needle assembly between the first position and to the second position and then back to the first position. The retainer and the engagement element are configured such that a holding force of the retainer is overcome by applying forces parallel to the axis of the needle. An inventive kit that includes an inserter and a driver for moving the needle assembly and a method of manufacturing the cannula cartridge are also disclosed.

Abstract: This disclosure concerns a method for removing gas and/or gas bubbles from a liquid medicament stored in a reservoir for an infusion pump device. The reservoir comprises a displacing member which is at least partly displaceable relative to the reservoir thereby enabling receiving mechanical oscillations in order to generate mechanical waves in the liquid medicament. The method comprises: providing the reservoir; and transmitting a mechanical oscillation to the displacing member of the reservoir thereby generating a mechanical wave in the liquid medicament for removing gas and/or gas bubbles from the liquid medicament.
