Abstract: A drug delivery device for conducting a medical therapy includes a housing with an exit port opening, and an exit port assembly, where said exit port assembly includes a rigid exit port sealing holder and a soft exit port sealing, and provides both a fluid-tight closure of the exit port opening and a fluid-tight connection between the housing and the rigid exit port sealing holder.

Abstract: A drug delivery device, such as a wearable patch injector or patch pump for subcutaneous delivery of a fluid medicament from a reservoir, includes a reusable module and a disposable. A protective lid of the disposable module ensures sterility prior to rupturing and reliability of drug delivery after the modules are connected via connecting interfaces of the modules due to the disposable module including a reservoir configured to hold a variable amount of liquid therein and a slidable plunger, and the reusable module including an actuation assembly configured to be extendable through the actuation opening into the disposable module and advance the plunger for drug delivery. The protective lid is ruptured when the reusable module and the disposable module are being connected.

Abstract: A cannula assembly includes a soft cannula, a rigid cannula, and a sealing sleeve. A soft cannula lumen surrounds at least a portion of the rigid cannula and provides a sliding connection. The sealing sleeve radially surrounds at least a portion of the soft cannula. A flange of the soft cannula has an extended wall thickness and is arranged at or near a proximal end of the soft cannula. An inner surface of the sealing sleeve engages an outer surface of the soft cannula and provides a sealing pressure radially between the rigid cannula and the soft cannula, defining a sealing area on an outer surface of the rigid cannula. A drug delivery device with the cannula assembly and an automatic insertion mechanism uses the sealing sleeve to ensure a fluid-tight, slidable connection between the soft cannula and the rigid cannula with improved sealing pressure, while allowing damage-free, cost-effective manufacturing.

Abstract: A module for a drug delivery device includes a first housing portion with a bearing element for supporting a neck or head portion of a first end of a reservoir and a second housing portion with an elastic contact element for supporting a second end of the reservoir opposite the first end. The first and second housing portions are configured to couple to each other in an assembled state in which the first and second housing portions form a cavity for accommodating the reservoir. The bearing element and the elastic contact element may each define a limiter or limiting structure of the cavity in a longitudinal direction of the cavity to secure or hold the reservoir free of play within the cavity. The elastic contact element may be is injection molded onto a surface of a body of the second housing portion.

Abstract: A fill port for filling a liquid medicament into a reservoir located inside a drug delivery device includes insert fixed in a passage of a wall of the drug delivery device, and a pierceable fill port sealing is sandwiched between the insert and both the housing of the drug delivery device and the reservoir to provide a fluid-tight sealing between the reservoir and the housing.

Abstract: A modular, semi-disposable patch pump for conducting a medical therapy includes a pump unit releasably connected to a reservoir unit by means of a bayonet connection; and a housing design for supporting both reliability and ease of use of said connection.

Abstract: A delivery device for administering a drug includes a housing, a reservoir and a drive device with a movable piston rod. The piston rod is guided through an aperture in an inner or outer wall of the housing. The aperture is sealed but allows the piston rod to move. The shape of the circumference of the cross-section of the piston rod is approximately a non-trivial curve of constant width.
