Abstract

The cover is made of a thin durable synthetic material preventing germs or other contaminating substances to get in contact with the instrument. The tip of the cover is transparent either like a miniature glass pane or an optical lens. The asymmetrical cross section of the cover facilitates the convenient accommodation of the tubes used for the insertion and removal of air and rinsing fluids. At least one duct must be made of a more rigid material in order to allow the insertion of a tool or to resist the forces of suction.

Description

Neuartige Schutzvorrichtung für medizinische Endoskopiegeräte zur Vermeidung der Übertragung von Infektionen bei der Untersuchung.Novel protective device for medical endoscopy equipment to avoid transmission of infections when examined.

Endoskopische Untersuchungen von Speiseröhre, Magen, Dünndarm und Dickdarm sind gängige und bewährte Untersuchungen für Diagnose und Therapie entsprechender Erkrankungen in diesem Bereich. Aufgrund des bisher zwangsweisen Kontaktes der Endoskopiegeräte, sowohl der Außenseite wie der innen liegenden Arbeitskanäle, mit Körperflüssigkeiten durch das bloße Einführen in Körperhöhlen und das Absaugen von Flüssigkeiten ist, um eine Übertragung von möglichen Infektionen zu vermeiden, eine aufwändige Reinigungs- und Desinfektionsprozedur nach jeder Endoskopie nötig.Endoscopic examinations of Esophagus, Stomach, small intestine and colon are common and proven Investigations for Diagnosis and therapy of corresponding diseases in this area. Due to the previously forced contact of the endoscopy devices, both the outside like the internal working channels, with body fluids by simply introducing them into Body cavities and the suction of liquids is about a transfer of possible Avoiding infections, a complex cleaning and disinfection procedure necessary after every endoscopy.

Das verursacht Kosten für Reinigungsgeräte, Desinfektionsmittel und Personal. Am gravierendsten ist aber der Umstand, dass durch diese Reinigung viel Zeit verstreicht bis zur nächsten Einsatzfähigkeit des Gerätes, wodurch organisatorische Schwierigkeiten und Kosten entstehen sowie ein hoher Geräteaufwand betrieben werden muss.This causes costs for cleaning devices, disinfectants and staff. The most serious thing is that this cleaning takes a lot of time until the next usability of the device, which creates organizational difficulties and costs as well a high cost of equipment must be operated.

Es handelt sich bei der Erfindung um einen kondomartigen Überzug für Endoskopiegeräte aus reißfestem in der Medizin üblicherweise verwendetem Kunststoff, der derart gestaltet ist, dass eine vollständige und wasser- und keimdichte Abschottung des Endoskops erreicht wird. Um die Erfindung schnell und leicht anwenden zu können, muss die Hülle wie eine Art Spitztüte geformt sein, die nach Einbringen des Endoskops in Längsrichtung gefaltet wird um das enge Anliegen der Hülle am Gerät zu ermöglichen (1).The invention is a condom-like cover for endoscopy devices made of tear-resistant plastic commonly used in medicine, which is designed in such a way that a complete and water-tight and germ-tight partitioning of the endoscope is achieved. In order to be able to use the invention quickly and easily, the case must be shaped like a kind of pointed bag, which is folded in the longitudinal direction after the endoscope has been inserted in order to allow the case to fit snugly on the device ( 1 ).

Der optische Kontakt zwischen Endoskopspitze und der Innenseite der Hüllenspitze wird z.B. durch Immersionsöl hergestellt, wobei die Hüllenspitze optische Eigenschaften wie eine Glasscheibe oder eine optische Linse haben muss.The optical contact between the endoscope tip and the inside of the envelope tip e.g. through immersion oil made with the tip of the envelope optical properties such as a glass pane or an optical lens must have.

Um Luft und Spülwasser zur Untersuchung insufflieren zu können, sind in der Hüllenwand Kanäle eingelassen, die das ermöglichen. Vorzugsweise sind die Kanäle nebeneinander angeordnet, was der Hülle eine leicht ovale Form gibt wodurch der Gesamtdurchmesser nicht wesentlich vergrößert wird (2). Diese Kanäle haben an der spitzenfernen Seite eine Verbindungsmöglichkeit zu modifizierten klassischen Endoskopie- Insufflations- und Spülventilen.In order to be able to insufflate air and rinsing water for examination, channels are built into the wall of the casing to enable this. The channels are preferably arranged next to one another, which gives the casing a slightly oval shape, as a result of which the overall diameter is not significantly increased ( 2 ). These channels can be connected to modified classic endoscopy insufflation and irrigation valves on the far side.

Mindestens ein weiterer Kanal muss so starrwandig sein, dass Endoskopiezangen eingeführt werden können und dass Flüssigkeiten abgesaugt werden können, ohne Kollaps des Kanals.At least one other channel is required be so rigid that endoscopic forceps are inserted can and that liquids can be suctioned off without collapse of the canal.

Die Lösung der bei Endoskopien vorhandenen Hygiene-Probleme ist mit den im Schutzanspruch 1 aufgeführten Merkmalen möglich.The solution of those available at endoscopes Hygiene problems is with the features listed in protection claim 1 possible.

Mit der Erfindung wird erreicht:
dass ein Kontakt des Endoskopiegerätes mit Körperflüssigkeiten vermieden wird.
dass gleichzeitig alle diagnostischen und therapeutischen Maßnahmen durchgeführt werden können, wie ohne diese Erfindung, aber eben ohne Infektionsgefahr.
dass keine Reinigungsmaschinen und keine Desinfektionsmittel benötigt werden, was die Umweltbelastung reduziert und Keimresistenzen verhindert und die Abnutzung an den Geräten vermindert wird.The invention achieves:
that contact of the endoscopy device with body fluids is avoided.
that all diagnostic and therapeutic measures can be carried out at the same time, as without this invention, but without the risk of infection.
that no cleaning machines and no disinfectants are required, which reduces the environmental impact and prevents germ resistance and the wear on the devices is reduced.
