A guide tube () for the rotatable mounting of a steering spindle () of a motor vehicle is described, wherein the guide tube () is rolled cylindrically from a single sheet-metal section and is connected at an axial contact point (), and wherein the guide tube () has elements (-) for the definably axially displaceable fastening in a bearing unit (). The guide tube () is characterized in that the elements (-) are designed in the form of at least two beads () which are distributed over the circumference, run axially, are formed circumferentially on both sides by ribs () expanding the cylinder circumference and are formed in the sheet-metal section. A production method for such a guide tube () is also described.

A sensor device for use in a medical fluid delivery system, or an infusion pump device, comprises a fluidic chamber with a deformable cover closing at least an area of the chamber and an optical detection system comprising at least one light emitter for emitting one or more incident light beams and a sensor unit for monitoring one or more reflected light beams is presented. In a pressurized state of the fluidic chamber, the deformable cover is deformed such that it forms an inflexion point area within the deformed cover. The one or more incident light beams emitted by the light emitter are directed on the cover such that the one or more incident light beams are reflected essentially in the inflexion point area.

A soft cannula is inserted into tissue and affixed to skin. A cannula arrangement moves within a housing and provides the soft cannula and a guiding needle extending through the cannula to temporarily stiffen it. A drive effects an insertion movement of the cannula arrangement from a first position, where a puncturing tip is pulled back relative to a face of the housing, into a second position, where the puncturing tip protrudes beyond the face, and automatically effects a retracting movement of the guiding needle into a third position, where the puncturing tip is pulled back relative to the face. The face is formed by a base plate affixed to the housing so that when the cannula arrangement is in the second position, the face detaches from the housing. A holder element is connected to the soft cannula and couples to the base plate in the cannula arrangement's second position.

Embodiments directed to a degassing device for removing gas bubbles from a liquid drug stream and an ambulatory infusion system are disclosed. The degassing device may comprise an inlet chamber with an inlet opening, an outlet chamber with an outlet opening, and a degassing opening. A hydrophilic membrane and a hydrophobic membrane, wherein the hydrophilic membrane fluidically couples the inlet chamber with the outlet chamber, enabling a transfer of liquid from the inlet chamber to the outlet chamber. The hydrophobic membrane fluidically couples the inlet chamber with the degassing opening, enabling a transfer of gas from the inlet chamber to the degassing opening. The hydrophilic and hydrophobic membranes being joined along a joint to establish a joined membrane, such that a contact line of a liquid-gas phase separation on the joined membrane does not coincide with the joint independent of an orientation of the degassing device with respect to gravity.
