Abstract: A holding device and an inserter are provided. The holding device includes a casing providing a cavity including walls, the was encompass a subcutaneous unit. The cavity includes a first side having an outlet opening, the outlet opening before use is covered with a penetrable or removable cover, and a second side comprising a layer having an outer surface and being penetrable, removable or flexible to transfer an impact from outside the layer to the subcutaneous unit. The casing includes a releasable attachment member corresponding to a member on the subcutaneous unit and a needle secured to the casing. An impact towards the outer surface of the layer pushes the subcutaneous unit at least partly out of the casing into a subcutaneous position, when the unit is in the subcutaneous position the releasable attachment member of the casing is released allowing detachment of the unit from the casing.

Abstract: An infusion tube system and a method for manufacture are provided. An infusion tube system including an infusion tube and a connector attached to the infusion tube at an end of the infusion tube is disclosed. The connector has a proximal end and includes a connector body extending from a distal end to a proximal end along a center axis and defining a cavity. The connector body includes an end wall with an inner surface, and at least one vent opening, and a sidewall extending from the end wall along the center axis with an inner and outer surface. The connector includes a membrane covering the at least one vent opening, the membrane being welded to the inner surface of the end wall along at least one welding seam including a first welding seam such that the membrane covers and seals the at least one vent opening.
