Als besonders zweckmäßig erweisen sich Materialien, die etwas durchlässig für das verwendete flüssige Druckmedium sind, wie beispielsweise Celluloseacetat, weil dadurch das Druckmedium gleichzeitig als Schmiermittel wirken kann. Die Befestigung der Enden des Schlauchgebildes an dem Rohr der Einführungshilfsvorrichtung geschieht auf übliche Weise durch Verkleben oder Verschweißen oder andere geeignete Befestigungsmittel, wie z. B. einen Schrumpfschlauch.thin-walled flexible structures are common. As particularly useful turn out to be materials that are somewhat permeable to the liquid pressure medium used are, such as cellulose acetate, because thereby the printing medium at the same time can act as a lubricant. Attaching the ends of the hose structure to the tube of the insertion aid is done in the usual way by gluing or welding or other suitable fastening means, such as e.g. B. a shrink tube.
Als Druckmedium kommen insbesondere Flüssigkeiten in Frage. Bei Verwendung von wäßrigem Medium ist ein Zusatz von z. B. Glycerin oder Paraffinum perliquidum zur Verbesserung der Gleiteigenschaften zweckmäßig. Liquids in particular come into consideration as the pressure medium. Using of aqueous medium is an addition of z. B. glycerine or paraffinum perliquidum useful to improve the sliding properties.

Es versteht sich von selbst, daß die Erfindung auch auf anderen Gebieten der Technik nutzbringend angewendet werden kann, wo das Problem des Zuganges für Endoskope und Spülvorrichtungen in nichtlinearen Höhlen besteht. Under an elongated medical device for examination or treatment Body cavities are particularly endoscopes, sampling devices and rinsing devices intended for rectal, oral or nasal introduction. It goes without saying that the invention can also be used beneficially in other areas of technology can be where the problem of access for endoscopes and irrigation devices in nonlinear caves.
Nachstehend wird die Erfindung anhand von Ausführungsbeispielen näher erläutert. The invention is explained in more detail below with the aid of exemplary embodiments explained.
F i g. 1 bis 3 zeigen den Erfindungsgegenstand schematisch in verschiedenen Phasen seiner Anwendung. F i g. 1 to 3 show the subject matter of the invention schematically in different ways Phases of its application.
F i g. 1 zeigt schemtaisch ein medizinisches Gerät 9, das z. B. ein Endoskop zur Untersuchung des Dickdarms sein kann, in der Ausgangsstellung. Das Gerät 9 ist durch das durch das Rohr 2 laufende Schlauchgebilde 4 geschoben. Im distalen Bereich 10 des Gerätes 9 ist das Schlauchgebilde 4 in mehreren Doppellagen aufgebracht, so daß das distale Ende 11 frei bleibt. Das Schlauchgebilde 4 liegt an dem Gerät 9 gerade so straff an, daß es beim Einführen in die Körperhöhle nicht auf dem Gerät 9 zurückgeschoben werden kann. Dieses Anliegen des Schlauchgebildes 4 auf dem Gerät 9 ist aus Gründen der Übersichtlichkeit zeichnerisch nicht dargestellt. F i g. 1 schematically shows a medical device 9, which z. B. a Endoscope for examining the colon can be in the starting position. That The device 9 is pushed through the hose structure 4 running through the tube 2. in the distal area 10 of the device 9 is the tubular structure 4 in several double layers applied so that the distal end 11 remains free. The hose structure 4 lies on the device 9 just so tight that it is not when inserted into the body cavity can be pushed back on the device 9. This concern of the hose structure 4 on the device 9 is not shown in the drawing for the sake of clarity.
Das proximale Ende 12 des Gerätes 9 ragt aus dem Schlauchgebilde 4 heraus, da beim Einschieben des Gerätes 9 unter Druckbeaufschlagung durch Druckanschlußstutzen 3 sich das proximale Ende 12 des Gerätes 9 auf die Einstülpfront 12 des Schlauchgebildes 4 zubewegt. Beim Einschieben des Gerätes 9 in das Schlauchgebilde 4 bewegt sich nämlich dessen Einstülpfront 13 nur halb so schnell wie das Gerät 9. The proximal end 12 of the device 9 protrudes from the tube structure 4, because when the device 9 is pushed in, it is pressurized through the pressure connection piece 3, the proximal end 12 of the device 9 is placed on the everting front 12 of the tube structure 4 closed. When the device 9 is pushed into the hose structure 4, it moves namely, its insertion front 13 only half as fast as the device 9.
F i g. 2 zeigt das Gerät 9 schematisch in einer Stellung, wo die äußerste Doppellage 14 des Schlauchgebildes 4 durch Vorschieben des Geräts 9 unter Druckbeaufschlagung durch den Druckanschlußstutzen 3 teilweise ausgestülpt ist. Das proximale Ende 12 des Gerätes 9 bewegt sich dabei in Richtung auf das Rohr 2. Um weiteren Raum zum Vorschieben des Geräts 9 zu bekommen, kann das Rohr 2 in Richtung distal gegenüber dem Gerät 9 verschoben werden. F i g. 2 shows the device 9 schematically in a position where the outermost double layer 14 of the hose structure 4 by pushing the device 9 under Pressurization through the pressure connection piece 3 is partially everted. The proximal end 12 of the device 9 moves in the direction of the tube 2. In order to get more space for advancing the device 9, the tube 2 can in the direction of be displaced distally with respect to the device 9.
F i g. 3 zeigt das Gerät 9 schematisch in einer Stellung, in der das Rohr 2 gegenüber dem Gerät 9 nach distal verschoben ist. Die dabei auf der distalen Seite des Rohrs freiwerdende Länge des Schlauchgebildes 4 wird jeweils auf das Rohr 2 aufgestülpt. Je nach Länge des aufzustülpenden Schlauchgebildes 4 wird in mehreren Lagen aufgestülpt. Der auf das Rohr 2 aufgestülpte Teil des Schlauchgebildes wird gewünschtenfalls durch geeignete Klemmen (in der Fig. nicht dargestellt) fixiert Um den auf das Rohr 2 aufgestülpten Teil des Schlauch- gebildes 4 zusätzlich gegen ein Abrutschen zu sichern, kann die Außenseite des Rohres 2 beispielsweise quergeriffelt sein. F i g. 3 shows the device 9 schematically in a position in which the tube 2 is displaced distally with respect to the device 9. The one on the distal Side of the pipe released length of the hose structure 4 is in each case on the pipe 2 turned upside down. Depending on the length of the tubular structure 4 to be turned on, several Layers turned upside down. The part of the tube structure that is slipped onto the tube 2 becomes if desired, fixed by suitable clamps (not shown in the figure) To get the part of the hose that is slipped onto the pipe 2 formed 4 additionally against To secure a slipping, the outside of the tube 2 can, for example, cross-corrugated be.
Im Falle eines Endoskopes zur Untersuchung des Dickdarms hat das Gerät 9 beispielsweise eine Länge von rund 2 m. Der im distalen Bereich 10 des Gerätes 9 in mehreren, vorzugsweise zwei bis drei Doppellagen aufgebrachte Teil des Schlauchgebildes 4 hat eine Länge von ungefähr 20 bis 40 cm. Die Länge des im distalen Bereich 10 des Gerätes 9 in Doppellagen aufgebrachten Teils des Schlauchgebildes 4 soll mindestens der Summe der Längen der beim Einführen zu erwartenden schwierigen Passagen entsprechen. Das proximale Ende 12 des Geräts soll aus dem proximalen Ende 7 des Rohres 2 um ein Stück herausragen, das der Summe der Längen der zu erwartenden schwierigen Passagen entspricht Es ist zweckmäßig, in der Ausgangsstellung den Abstand der Einstülpfront 13 vom proximalen Ende 7 des Rohres 2 maximal auf die Hälfte des Abstandes zwischen dem proximalen Ende 12 des Gerätes 9 und dem proximalen Ende 7 des Rohres 2 einzustellen. Das Rohr 2 weist eine Länge von etwa 20 cm auf. Sein innerer Durchmesser ist etwas größer als der Außendurchmesser des Gerätes 9 am distalen Ende 11. In the case of an endoscope for examining the colon, this has Device 9 has a length of around 2 m, for example, and the one in the distal area 10 of the device 9 part of the hose structure applied in several, preferably two to three double layers 4 is approximately 20 to 40 cm in length. The length of the in the distal area 10 of the device 9 applied in double layers part of the hose structure 4 should at least correspond to the sum of the lengths of the difficult passages to be expected during insertion. The proximal end 12 of the device is designed to extend from the proximal end 7 of the tube 2 to a piece protruding that is the sum of the lengths of the difficult passages to be expected It is useful to adjust the distance between the front panel in the starting position 13 from the proximal end 7 of the tube 2 to a maximum of half the distance between the proximal end 12 of the device 9 and the proximal end 7 of the tube 2. The tube 2 has a length of about 20 cm. Its inside diameter is something larger than the outer diameter of the device 9 at the distal end 11.
