1. Ein medizinischer Adapter zum Verbinden einer durchstoßbaren Stelle mit einem Fluid-Konnektor-Steckstück mit:
einem Körper, der ein erstes Ende und ein zweites Ende hat;
einen nadellosen Sitz, das an dem ersten Ende des Körpers angeordnet ist und einen Fluidstrom-Anschluß hat;
einer angeschärften Kanüle, die an dem zweiten Ende des Körpers angeordnet ist, wobei die Kanüle eine angeschärfte Spitze hat;
einem internen Fluidkanal, der den Fluidstrom-Anschluß des nadellosen Sitzes mit der geschärften Kanüle verbindet, so daß das Fluid zwischen den beiden fließen kann;
einem ersten Klemmarm, der an dem Körper montiert ist, wobei sich der erste Klemmarm zu der Spitze der angeschärften Kanüle erstreckt und ein distales Ende hat; und
einer Klaue an dem distalen Ende des ersten Klemmarms, die zu der Richtung der angeschärften Kanüle weist und die angeschärfte Spitze schützt.
2. Der medizinische Adapter nach Anspruch 1, weiter mit einer Feder, die mit der ersten Klemme verbunden ist, um das distale Ende des ersten Klemmarms in Richtung auf die angeschärfte Spitze der Kanüle zu zwingen.
3. Der medizinische Adapter nach Anspruch 2, wobei die Feder ein nachgiebiges Verbindungselement aufweist, das zwischen dem ersten Klemmarm und dem zweiten Körper angebracht ist.
4. Der medizinische Adapter nach Anspruch 1, wobei die Klaue einen angeschärften Punkt aufweist, der zu der angeschärften Kanüle weist.
5. Der medizinische Adapter nach Anspruch 1, mit
- einem Abdichtungsabschnitt an dem zweiten Ende des Körpers, der eine Größe hat, die ausgewählt ist, um in die Durchstoßung der durchstoßbaren Stelle zu passen und um eine flüssigkeitsdichte Abdichtung mit dem Röhrchen zu schaffen und wobei die Klaue einen angeschärften Punkt aufweist, der zu der angeschärften Kanüle weist;
- einem Handstück, das an dem ersten Klemmarm derart befestigt ist, daß die Aufbringung einer Kraft auf das Handstück die Klaue des ersten Klemmarms veranlassen wird, sich von der angeschärften Kanülenspitze weg zu bewegen; und
- einer Feder, die mit dem ersten Klemmarm verbunden ist, um das distale Ende des ersten Klemmarms in Richtung auf die angeschärfte Spitze der Kanüle zu zwingen, wobei die Feder ein nachgiebiges Verbindungsstück aufweist, das zwischen dem ersten Klemmarm und dem Körper angebracht ist.
6. Der medizinische Adapter nach Anspruch 1 und Anspruch 5, weiter mit:
einem zweiten Klemmarm, der an dem Körper dem ersten Arm gegenüberliegend angebracht ist, wobei der zweite Klemmarm sich zu der Spitze der angeschärften Kanüle erstreckt und ein distales Ende aufweist; und
- einer Klaue an dem distalen Ende des zweiten Klemmarms, die in Richtung der angeschärften Kanüle die angeschärfte Kanüle schützend weist.
7. Der medizinische Adapter nach Anspruch 6, wobei jede Klaue eine angeschärfte Fläche und zwei scharfe Punkte, die zu der angeschärften Kanüle weisen, aufweist.
8. Der medizinische Adapter nach Anspruch 6, wobei jede Klaue eine Kerbe aufweist, die in Richtung der angeschärften Kanüle weist.
9. Der medizinische Adapter nach einem der Ansprüche 1 bis 8, weiter mit einem Handstück, das an dem ersten Klemmarm derart angebracht ist, daß das Aufbringen einer Kraft auf das Handstück die Klaue des ersten Klemmarms veranlaßt, sich von der angeschärften Kanülenspitze weg zu bewegen.
10. Der medizinische Adapter nach Anspruch 6, weiter mit einem Handstück, das an jedem der Klemmarme derart angebracht ist, daß das Aufbringen einer ausreichenden Kraft auf die Handstücke die Klauen der Klemmarme dazu veranlassen wird, sich von der angeschärften Kanülenspitze weg zu bewegen.
11. Der medizinische Adapter nach Anspruch 9 oder Anspruch 10, wobei das Handstück oder die Handstücke derart angeordnet ist, daß das Aufbringen eines Drucks auf das bzw. die Handstücke in eine Richtung hin zu dem Adapterkörper das bzw. die Klauen dazu veranlassen wird, sich von der angeschärften Kanulenblindspitze weg zu bewegen.
12. Der medizinische Adapter nach Anspruch 11, wobei das Handstück oder jedes der Handstücke derart angeordnet ist, daß das Aufbringen eines Drucks auf das bzw. die Handstücke in eine Richtung weg von dem Adapterkörper die Klaue bzw. die Klauen veranlassen wird, sich von der angeschärften Kanülenspitze weg zu bewegen.
13. Der medizinische Adapter nach einem der vorangehenden Ansprüche, wobei die Länge des Klemmarms oder jedes der Klemmarme und der Klaue oder jeder der Klauen zu dem Klemmarm oder dem jeweiligen Klemmarm derart ausgewählt ist, daß der Klemmarm oder jeder der Klemmarme über die angeschärfte Spitze der Kanüle hinausragt, um zu verhindern, daß die angeschärfte Spitze den Verwender des Adapters verletzt, bis der Arm oder jeder der Arme und die Klaue oder jede der Klauen von der angeschärften Spitze weg bewegt werden.
14. Der medizinische Adapter nach einem der vorangehenden Ansprüche, wobei der Körper einen Abdichtabschnitt an dem zweiten Ende aufweist, dessen Größe so ausgewählt ist, daß er in die Durchstoßuing an der durchstoßbaren Stelle paßt und eine fluid-dichte Abdichtung mit Röhrchen bewirkt.
15. Der medizinische Adapter nach Anspruch 14, wobei der Körper weiter einen konischen Abschnitt aufweist, der zwischen der angeschärften Kanüle und dem Abdichtabschnitt angeordnet ist.
16. Der medizinische Adapter nach einem der vorangehenden Ansprüche, wobei die Länge der angeschärften Kanüle und der Klemmarm derart ausgewählt ist, daß sie lang genug sind, um durchstoßbare Stellen an unterschiedlichen Orten zu erreichen.
17. Ein medizinischer Adapter zum Verbinden einer durchstoßbaren Stelle mit einem Fluid-Konnektor-Steckstück, mit:
einem Körper mit einem ersten Ende und einem zweiten Ende;
einem Aufnahme-Konnektorstück, das an dem ersten Ende des Körpers angeordnet ist und einen Fluidstrom-Anschluß hat;
einer angeschärften Kanüle, die an dem zweiten Ende des Körpers angeordnet ist, wobei die Kanüle eine angeschärfte Spitze hat;
einem internen Fluidkanal, der den Fluidstrom-Anschluß des Aufnahme-Verbindungsstücks mit der angeschärften Kanüle verbindet, so daß ein Fluid zwischen den beiden fließen kann;
einer ersten Hülse, die an dem Körper befestigt ist und die angeschärfte Kanüle aufnimmt; und
einer zweiten Hülse, die an dem Körper angebracht ist und die angeschärfte Kanüle aufnimmt, wobei der zweite Mantel eine Länge hat, die wenigstens so groß wie die angeschärfte Kanüle ist.
18. Der medizinische Adapter nach Anspruch 17, wobei die zweite Hülse länger als die erste Hülse ist und außerhalb der ersten Hülse angeordnet ist.
19. Der medizinische Adapter nach Anspruch 17, weiter mit einer erhabenen Rippe, die an der ersten Fläche einer der Hülsen angeordnet ist.
20. Der medizinische Adapter nach Anspruch 19, wobei die zweite Hülse langer als die erste Hülse und außerhalb der ersten Hülse angeordnet ist und die erhabene Rippe auf der zweiten Hülse ausgebildet ist.
