Abstract: An endoscope with a contamination protection device for protecting the endoscope and a person performing an examination on a patient from contamination. The endoscope has a rigid or flexible shaft, an inner sleeve configured to be unrolled from a rolled-up state over the shaft to cover the shaft in an airtight, watertight and germ-tight manner, and an outer sleeve configured to envelop the inner sleeve. The outer sleeve is connected in an airtight, watertight and germ-tight manner only to a proximal end of the inner sleeve at the proximal end of the shaft and so as to extend beyond the tip of the shaft. The outer sleeve and the inner sleeve together provide a protection volume between a body orifice of a patient to be examined and a proximal end of the for collecting body fluids released by the patient during the examination.

Abstract: An endoscope for the minimal invasive examination or surgical treatment of a patient has a flexible tubular shaft for insertion into the patient, a grip attached to a proximal end of the shaft for holding the endoscope, and at least one hollow tube. The shaft has at least one groove extending axially along an outer face of the shaft and in which the tube is removably housed. The tube has at least one working channel for guiding a surgical instrument, and/or carrying water or air to or providing suction at the shaft distal end. The shaft groove and the tube are dimensioned relative one another such that at least one free section of the tube is afforded play in the groove. In the straight extended state of the shaft, the at least one free section has an exterior cross-section which is slightly smaller than an interior cross-section of the groove.

Abstract: The invention relates to a thermally insulated conduit pipe, comprising at least one medium pipe, at least one thermal insulation arranged around the medium pipe, and at least one outer jacket arranged around the thermal insulation, wherein the outer jacket possibly comprises a barrier made of plastic, and wherein the thermal insulation comprises a foam, the cell gas of which contains at least 10 vol % HFOs. Such conduit pipe has good insulating behavior, good environmental balance, and is easily producible.

Abstract: The invention relates to the use of special polymer layers as barriers, in particular as barrier layers in composite materials. Suitable polymers for the polymer layer are copolymers consisting of ethylene and vinyl alcohol or consisting of ethylene and carbon monoxide or consisting of ethylene and carbon monoxide and propylene. These barrier layers exhibit a selective barrier effect with respect to different gases, the barrier effect being especially effective with respect to HFOs. On account of these properties, such barrier layers can positively affect insulating properties, for example in thermally insulated pipes.
