Abstract: An insertion device for an infusion set, the device including a retention means by which the infusion set can be temporarily held on the device and drive means including a pretensionable spring for providing drive energy for an insertion movement of the infusion set, wherein the infusion set is secured by the retention means by clamping when the retention means is in an engage position and can then be moved, with simultaneous pretensioning of the spring, to an insertion movement starting position, wherein the infusion set is already separated from the retention means at the start of the insertion movement, and wherein the infusion set moves through at least part of the insertion movement free of the retention means.

Abstract: An insertion device for an infusion set, the insertion device including a two-part housing and a retainer or a retention means by which the infusion set can be temporarily held on the device, and a driver or a drive means including a pretensionable spring for providing the drive energy for an insertion movement of the infusion set, wherein one of the housing parts can be pivoted relative to the other to engage the infusion set and, after engagement of the infusion set, they can be pivoted again, as a result of which the spring is pretensioned and the insertion device is brought to a ready-to-use state. After the insertion movement has been triggered, the infusion set is separated from the device, such that it can execute the greatest part of the insertion movement free of the retainer.

Abstract: An insertion head for medical use, including a housing formed by two housing parts, a puncture needle and a flexible cannula supported by the puncture needle, wherein before use the puncture needle and cannula are arranged in a protected position inside the housing and can be deployed by gripping the housing parts and moving at least one of the parts relative to the other, wherein upon depolyment the puncture needle and cannula can be inserted into the body of a patient, and wherein after insertion the puncture needle can be removed from the cannula by moving the housing and puncture needle away from the body counter to the direction of insertion, the puncture needle being automatically pivoted into a protected position in the housing.

Abstract: Implantable cylindrical device for connecting a hose arranged outside of the human or animal body to a hose arranged inside of the said body, wherein an anchoring plate falling away peripherally from the skin surface is arranged around the cylindrical device. This allows the skin to unroll over the anchoring plate subject to a tilting moment of the port body.
