Insertion head for medical or pharmaceutical applications

An insertion head for medical or pharmaceutical applications, comprising:

• a) a housing comprising a first housing part and a second housing part movable relative to each other;
• b) a base separable from the housing;
• c) a flexible insertion device stabilized by a puncture device, the insertion device and the puncture device each having a free end and mounted so as to be jointly movable relative to the housing, the end of the insertion device opposite the free end being securely connected to an insertion device housing,
• d) the insertion device and the puncture device being pivotal relative to the housing from a protected position, in which the free ends are inside the housing, to an insertion position in which the free ends are outside the housing, the insertion device housing pivoting with the insertion device;
• and
• e) a coupling converting the relative movement of the two housing parts into a pivotal movement of the insertion device and the puncture device from the protected position to the insertion position, wherein when the puncture device is in the insertion position, the puncture device is connected to the housing and releasable from the insertion device, and wherein after insertion of the insertion device and the puncture device, the puncture device is removed from the insertion device, the insertion device housing, and the base by moving the housing in a direction counter to the direction of insertion, the puncture device moving automatically to the protected position after removal from the insertion device, the base and insertion device housing remaining on a patient and the insertion device remaining in the patient.

An insertion head for medical or pharmaceutical applications, comprising:

• a) a housing comprising a first housing part and a second housing part, the first and second housing parts being movable relative to each other;
• b) a base separable from the housing, the base having an underside;
• c) a flexible insertion device, which is stabilized by a puncture device, the insertion device and the puncture device each having a free end and being mounted so as to be jointly pivotal relative to the housing, the end of the insertion device opposite the free end being securely connected to an insertion device housing,
• d) the insertion device and the puncture device being pivotal relative to the housing from a protected position, in which the free ends of the insertion device and of the puncture device are arranged inside the housing and/or the base, to an insertion position, in which the free ends protrude from the housing and/or the base in such a way that they can be inserted into organic tissue, the insertion device housing pivoting with the insertion device, and
• e) a coupling converting the relative movement of the two housing parts into a pivotal movement of the insertion device and the puncture device from the protected position to the insertion position, wherein when the insertion device and the puncture device are in the insertion position and protruding from the base and the underside of the base is placed on the organic tissue, the insertion device and the puncture device are inserted into the organic tissue, wherein when the puncture device is in the insertion position, the puncture device is connected or connectable to the housing and released or releasable from the insertion device, and wherein after insertion of the insertion device and of the puncture device into the organic tissue, the puncture device is removed from the base, the insertion device housing, and the insertion device by moving the puncture device in a direction counter to the direction of insertion, the base and the insertion device housing remaining on the organic tissue and the insertion device remaining in the organic tissue, and further comprising restoring means for pivoting the puncture device automatically to the protected position.
