Abstract: The present invention relates to an endoscope cover-sheathed endoscope having an endoscope in which an insertional part is extending from an operational part, and an endoscope cover made up of an insertional part cover, an operational part cover, and a universal cord cover, which shield the endoscope and are concatenated in that order from the distal end of the endoscope.The operational part cover overlaps and shields the margin of the insertional part cover, while the operational part cover overlaps and shields the margin of the universal cord cover. The endoscope will not therefore be bared.The proximal portion of an insertional part cover skin of the insertional part cover, which shields the insertional part and consists of a distal part, an insertional part cover skin, and an operational endoscope cover locking cap, is formed as a rigid skin made of Teflon, urethane, or other resin having such rigidity that will not cause a damage resulting from friction with other member, for example, a rigid sheath.

Abstract: A cover type endoscope apparatus includes a cover, a covered endoscope which is inserted into this cover and used, and a cover holder for holding various peripheral units connected to the covered endoscope and the cover, wherein an indication device for indicating whether or not an apparatus should handle a clean area in a sterile state or other area is provided in each of the components.

Abstract: An endoscope apparatus of a type having a cover for covering the endoscope composed of a cover for an insert, a cover for a control unit, and a universal-cord cover, and the endoscope which uses the endoscope cover to cover the control unit having a handle in the body of the control unit, an elongated insert extending from the control unit to the leading portion and a universal cord extending from the control unit. At least two members of all members that form the cover for the insert of the endoscope cover, for example, a leading unit and an acceptor for fixing the control unit of the endoscope, are made of the same material such as polysulfone which is a thermoplastic resin which can be recycled, or all members forming the cover for the insert are made of a material which can be subjected to a combustion process, or the cover for the control unit integrally covers the insert and the handle of the endoscope with the endoscope cover.

Abstract: An endoscope system includes an endoscope having internal conduits, a cleaning solution supply portion formed in the endoscope and communicating with the internal conduits, and a solution feed unit for feeding a cleaning solution to the cleaning solution supply portion. The internal conduits are formed such that the cleaning solution supplied from the cleaning solution supply portion to the internal conduits by the solution feed unit flows in all the flow paths of the internal conduits at a flow speed almost equal to that in the cleaning solution supply portion.
