CA 2375953

Safety sheaths for endoscopes are provided. One safety sheath (30) has an elongated hollow sheath (36) having a first end (32) and a second end (38) and having a wall of flexible material between the first and second ends. The sheath is compressed before the sheath is placed over the endoscope. When the endoscope (10) is inserted into a patient, the sheath opens, thereby covering the endoscope. The covering (30) also has an endcap (40) for inserting the endoscope and a ring (96) attached to one of the first and second ends of the sheath. When the endoscope is removed from the patient, the sheath inverts, thereby retaining the contaminants on the inside of the sheath. Another version of the safety sheath has two sheaths, an inner (136, 336) and an outer sheath (236, 436). This provides added safety and prevents the operator's hands from contamination with body fluid. Still another version of the safety sheath has a drape (200) having an inlet (202, 204) for an endoscope and a finger access. Also provided is a moveable sheath (536) that fits over an endoscope. The moveable sheath is particularly useful for inserting the endoscope into, and removing the endoscope from, the patient.

L'invention concerne des manchons de sécurité pour endoscopes. Il s'agit d'un manchon creux, allongé, à première et seconde extrémités, et à paroi en matériau flexible entre lesdites extrémités, avec compression de ce manchon avant placement sur l'endoscope. Une fois l'endoscope introduit dans le corps du patient, le manchon s'ouvre, couvrant ainsi l'endoscope. Il existe un opercule terminal pour l'insertion de l'endoscope et une bague fixée à l'une des deux extrémités mentionnées. Au retrait de l'endoscope, le manchon s'inverse, retenant ainsi les contaminants à l'intérieur. Selon une variante, le manchon de sécurité est double, avec des manchons interne et externe, ce qui améliore la sécurité et empêche toute contamination de la main de l'opérateur par les fluides corporels. Selon une autre variante, le manchon de sécurité comporte un drapé doté d'une entrée pour l'endoscope et d'un accès pour les doigts. L'invention concerne en outre un manchon amovible qui s'adapte sur un endscope, particulièrement utile pour l'insertion et l'extraction de l'endoscope.
