  • B Kanüle ist in ihrer gesamten Länge mit transparenter blutundurchlässiger Folie (7) ummantelt; die Folie (7) ist exakt so bemessen, dass bei Zug die Kanülenspitze in den inneren Bereich des Kanülenfängers (6) gleitet.B cannula is in its entire length with transparent blood-impermeable film ( 7 ) encased; the foil ( 7 ) is exactly dimensioned so that when Zug the cannula tip in the inner region of the Kanülenfängers ( 6 ) slides.
  • C Die Seitenlänge der Ummantelungsfolie ist einseitig (z. B. rechts) mehrere Millimeter länger als auf der Gegenseite (z. B. links)C The side length the cladding foil is one-sided (eg right) several millimeters longer as on the opposite side (eg on the left)
  • D Die Ummantelungsfolie (7) ist mit der Kanülenbasis (9) und mit dem Kanülenspitzenfänger (6) fest verbunden.D The wrapping film ( 7 ) is with the cannula base ( 9 ) and with the cannula tip catcher ( 6 ) firmly connected.
  • E Die Kanülenspitze ist vor der Verwendung mit einer Plastikkappe (1) überzogen.E The tip of the cannula is covered with a plastic cap before use ( 1 ) overdrawn.
  • F Die Plastikkappe (1) ist klebend (2) mit einem pflasterähnlichem Wundverschlußsystem (3) und einer Plastikplatte (4) verbunden.F The plastic cap ( 1 ) is adhesive ( 2 ) with a plaster-like wound closure system ( 3 ) and a plastic plate ( 4 ) connected.
  • G Die Plastikkappe (1) kann mit einer Klebefolie (2) von der Kanülenspitze direkt vor Gebrauch abgezogen werden; die Kanülenspitze ist dann sichtbar; die Plastikplatte (4) kann mit dem Wundverschlußsystem (3) gemeinsam in Richtung Kanülenbasis (9) zurückgestreift werden (2); dabei ist die Öffnung des Wundverschlußsystems für die Kanüle derart, dass das Verschlußsystem 45–90 Grad gekippt werden kann. Das Blutentnahme bzw. Injektionssystem ist nun einsatzbereit.G The plastic cap ( 1 ) can with an adhesive film ( 2 ) are withdrawn from the cannula tip just before use; the cannula tip is then visible; the plastic plate ( 4 ) can be used with the wound closure system ( 3 ) together in the direction of the cannula base ( 9 ) are withdrawn ( 2 ); In this case, the opening of the wound closure system for the cannula is such that the closure system can be tilted 45-90 degrees. The blood collection or injection system is now ready for use.
  • H Unterhalb der Plastikkappe (1) befindet sich das pflasterähnliche Wundverschlusssystem (3) welches auf einer Plastikplatte (4) fixiert ist.H Below the plastic cap ( 1 ) is the plaster-like wound closure system ( 3 ) which on a plastic plate ( 4 ) is fixed.
  • I Das Wundverschlußsystem (3) ist außen in Richtung Kanülenspitze klebend und im Bereich der Kanülenspitze überlappend gefaltet. (4, 5)I The wound closure system ( 3 ) is stuck outside in the direction of the tip of the needle and folded in an overlapping manner in the area of the cannula tip. ( 4 . 5 )
  • J Das Wundverschlußsystem (3) wird beim Zurückziehen der Kanüle (8) aus der Haut zeitgleich manuell mit der Plastikplatte (4) auf die Haut gepresst und klebt dort.J The wound closure system ( 3 ) is when retracting the cannula ( 8th ) from the skin at the same time manually with the plastic plate ( 4 ) pressed on the skin and sticks there.
  • K Der überlappende Pflasterteil am Wundverschlußsystem (3) verschließt die Punktionsstelle. (4, 5). Das Wundverschlußsystem (3) klebt außen unter manueller Fixierung seitens des Anwenders auf der Haut, und klebt innen auf der Plastikplatte (4). Die Plastikplatte (4) überragt mindestens auf einer Seite das pflasterähnliche Wundverschlußteil um 1–2 cm und kann am Ende 45 Grad abgewinkelt sein. Es dient als Halterung zum Vorschieben des Wundverschlusses in Richtung Kanülenspitze vor Entfernung der Kanüle aus der Haut des Patienten. Während des Zurückziehens der Kanüle wird zeitgleich die Plastikplatte vorgeschoben und auf die Injektionsstelle gepresst. Danach verbleibt sie auf der Haut als Druckpunkt für die Finger des Anwenders bzw. des Patienten. Mit der Plastikplatte (4) wird das punktierte Gefäß komprimiert und mit dem sich überlappenden Wundverschlußsystem (3) wird die Punktionsstelle abgedeckt. Die Plastikplatte (4) ist nach innen (Richtung Kanülenbasis) mit dem Kanülenspitzenfänger (6) klebend verbunden. Kurz vor Entfernung der Kanüle aus der Haut wird die Plastikplatte (4), wie oben beschrieben, auf die Haut gepresst und die Kanüle mit dem Kanülenspitzenfänger (6) wird durch Zug von der Plastikplatte (4) getrennt. Der Kanülenspitzenfänger (6) löst sich beim Zug der Plastikplatte (4) von dieser, indem sie auf die gegenüberliegende Seite kippt, an welcher sie noch zuletzt mit der Klebefolie (5) fixiert ist. Die Klebefolie (5) ist auf jener Seite länger, an welcher auch die Ummantelung der Kanüle etwas länger ist als die Gegenseite. Durch das Kippen entgleitet die Kanüle aus der zentralen Kanülenfängeröffnung und verschwindet im Kanülenfänger und verkantet sich dort. (3, 6)K The overlapping patch part on the wound closure system ( 3 ) closes the puncture site. ( 4 . 5 ). The wound closure system ( 3 ) externally adheres to the skin under manual fixation by the user, and sticks inside on the plastic plate ( 4 ). The plastic plate ( 4 ) protrudes at least on one side of the plaster-like wound closure part by 1-2 cm and can be angled at 45 degrees at the end. It serves as a holder for advancing the wound closure in the direction of the cannula tip before removal of the cannula from the skin of the patient. During retraction of the cannula, the plastic plate is simultaneously advanced and pressed onto the injection site. Thereafter, it remains on the skin as a pressure point for the fingers of the user or the patient. With the plastic plate ( 4 ), the punctured vessel is compressed and filled with the overlapping wound closure system ( 3 ) the puncture site is covered. The plastic plate ( 4 ) is inward (cannula base) with the cannula tip catcher ( 6 ) adhesively bonded. Shortly before removing the cannula from the skin, the plastic plate ( 4 ), as described above, pressed onto the skin and the cannula with the cannula tip catcher ( 6 ) is removed by pulling from the plastic plate ( 4 ) separated. The cannula tip catcher ( 6 ) dissolves when pulling the plastic plate ( 4 ) of this, by tipping on the opposite side, where they last with the adhesive film ( 5 ) is fixed. The adhesive film ( 5 ) is longer on the side at which the sheath of the cannula is slightly longer than the opposite side. By tilting, the cannula slips out of the central cannula catcher opening and disappears into the cannula catcher and creases there. ( 3 . 6 )
  • L Der Kanülenspitzenfänger (6) sichert die Nadel nach dem Zurückziehen aus der Haut. (6)L The cannula tip catcher ( 6 ) secures the needle after retraction from the skin. ( 6 )
  • M Die Kanülenspitze verkantet sich im Kanülenspitzenfänger (6) automatisch, bedingt durch die unterschiedliche Seitenlänge der Folienummantelung und der unterschiedlichen seitlichen Verklebung. (3). Die Kanülenummantelung (7) (Folie) wird beim Zurückziehen der Kanüle aus der Haut automatisch in Richtung Kanülenspitze gezogen, da sie am Kanülenspitzenfänger (6) fixiert ist und diese wiederum an der Plastikplatte (4) hängt; die Bewegung wird durch manuelles fixieren der Plastikplatte (4) und zurückziehen der Kanüle erzwungen.M The cannula tip creases in the cannula tip catcher ( 6 ) automatically, due to the different side length of the foil coating and the different lateral bonding. ( 3 ). The cannula casing ( 7 ) (Foil) is automatically pulled in retraction of the cannula out of the skin in the direction of the tip of the needle, since it at the cannula tip catcher ( 6 ) is fixed and this in turn on the plastic plate ( 4 ) hangs; the movement is done by manually fixing the plastic plate ( 4 ) and withdrawing the cannula forced.
  • N Als Ergebnis zeigt sich, dass die Einstichstelle mit pflasterähnlichem Material überzogen ist, welche über die Plastikplatte (4) vom Anwender oder Patienten weiter komprimiert werden kann bis die Nachblutung gestillt ist.N As a result, it is shown that the puncture site is covered with plaster-like material, which over the plastic plate ( 4 ) can be further compressed by the user or patient until the Bleeding is breastfed.
  • O Die Kanülenspitze ist gesichert und verkantet im Kanülenspitzenfänger (6); (6) die Kanüle ist komplett ummantelt von der Folie (7); (3) ein unbeabsichtigter Blutkontakt ist seitens des Anwenders fast nicht mehr möglich.O The cannula tip is secured and wedged in the cannula tip catcher ( 6 ); ( 6 ) the cannula is completely covered by the foil ( 7 ); ( 3 ) Accidental blood contact is almost impossible on the part of the user.

Hier besorgt ein Spanner (12), dass beim Herausziehen der Kanüle (8) aus der Haut die Kanülenspitze von dem Kanülenspitzenfänger (6) automatisch gesichert wird (7).Here, a tensioner ( 12 ), that when pulling out the cannula ( 8th ) from the skin the cannula tip of the cannula tip catcher ( 6 ) is automatically backed up ( 7 ).

Zum Wundverschluß ist aber weiterhin eine manuelle Kompression des Wundverschlußsystems auf die Einstichstelle notwendig.To the Wound closure is but still a manual compression of the wound closure system the puncture site necessary.

Der Spanner (12) kann, wie in 7 dargestellt, durch ein biegsames Plastikstäbchen erzeugt werden, welches außerhalb der Plastikummantelung zwischen Kanülenbasis und Kanülenspitzenfänger angebracht wird und im Transportzustand mittels einer Klebefolie in Vorspannung gehalten wird.The tensioner ( 12 ) can, as in 7 represented by a flexible plastic strip which is mounted outside the plastic casing between the cannula base and cannula tip catcher and is held in the transport state by means of an adhesive film in bias.

Nach Lösen dieser Klebefolie (11) wird bis zur erfolgten Venenpunktion der Spanner (12) mit dem Finger fixiert.After loosening this adhesive film ( 11 ) until the venipuncture has been performed, the tensioner ( 12 ) fixed with the finger.

Während der Injektion bzw. Blutentnahme muss diese Fixierung zwangsläufig beendet werden, da die Hand zur Bedienung des Spritzenkolbens benötigt wird, so dass der Spanner (12) sich gerade aufrichtet und den Kanülenspitzenfänger (6) in Richtung Einstichstelle und Kanülenspitze führt.During the injection or blood collection, this fixation must be terminated necessarily because the hand is needed to operate the syringe plunger, so that the tensioner ( 12 ) is straightening up and the cannula tip catcher ( 6 ) leads in the direction of puncture site and cannula tip.

Sobald die Kanüle aus der Haut entfernt wird, fängt der Kanülenspitzenfänger, angetrieben durch den Spanner, die Kanülenspitze auf und sichert sie. (6) Der Aufbau mit Plastikummantelung, Plastikplatte und Wundverschluss soll wie bei Patentanspruch 1 sein.Once the cannula is removed from the skin, the cannula tip catcher, driven by the tensioner, captures and secures the cannula tip. ( 6 The structure with plastic sheath, plastic plate and wound closure should be as in claim 1.
