Abstract: A medical or pharmaceutical stopper (11) serves to seal the container volume of a container for receiving a liquid for medical, pharmaceutical, or analytical use. The stopper comprises a stopper pre-mold body (17) made of a pre-mold material and at least one stopper mold-on body (20) made of a mold-on material. Furthermore, the plunger comprises at least one barrier laminate (21) made of a laminate material laminated onto the stopper pre-mold body (17) and at least partially overmolded by the stopper mold-on body (20). The barrier laminate (21) is arranged between the stopper pre-mold body (17) and the stopper mold-on body (20). The barrier laminate (21) covers at least 30% of a sealing cross-section (Q) of the stopper.

Abstract: A medical or pharmaceutical stopper (3) is used to seal the container volume of a container for receiving a liquid (5) for medical, pharmaceutical, or analytical use. The stopper has a stopper base body (6) made of a base body material and a stopper overmold section (7) made of an overmolding material, via which the stopper (3) can be sealingly placed on an inner wall (8) of the container. A method for manufacturing an embodiment of the stopper comprising a stopper pre-mold body, a stopper mold-on body, and an at least partially overmolded barrier laminate, is additionally provided. The result is a medical stopper with an improved practical value.

Abstract: A mobile infusion pump is used for the constant delivery of a fluid medium. The infusion pump comprises a balloon body for receiving the medium as well as a filling unit and a delivery unit that are in a fluid connection with the balloon body for filling the medium into the balloon body and delivering the medium from the balloon body to a patient. A throttling unit defines a delivery flow rate of the medium. By means of a plurality of continuous longitudinal ribs arranged on a part of the balloon body configured as a tube body, the expansion behavior of the balloon body is improved.
