Conduit connection device for an insertion-instrument and endoscope apparatus

An endoscope apparatus, comprising:

• an endoscope;
• a plurality of fluid circulation lines connecting the endoscope and an external fluid circulation device, the plurality of fluid circulation lines each including a relay part;
• a plurality of conduit connectors;
• and
• a plurality of interference components,
• wherein the plurality of interference components is attached to the plurality of conduit connectors such that, in a first connection combination, each of the plurality of conduit connectors are attached to a respective relay part of the plurality of fluid circulation lines, and, in other than the first connection combination, at least one of the plurality of conduit connectors are prevented from being attached in a second connection combination.

A conduit connection device for an insertion-instrument, comprising:

• a plurality of conduit connectors;
• and
• a plurality of interference components,
• wherein a first end of each of a plurality of fluid circulation lines has one of the plurality of conduit connectors attached thereto,
• wherein a first end of each of a plurality of relay fluid circulation lines has one of the plurality of conduit connectors attached thereto,
• wherein the conduit connectors on the first end of each of the plurality of fluid circulation lines are configured to cooperate with the conduit connectors on the first end of each of the plurality of relay fluid circulation lines to form a connection,
• wherein the plurality of interference components are attached to the plurality of conduit connectors such that, in a first connection combination, the conduit connectors on the first end of each of the plurality of fluid circulation lines cooperate with the conduit connectors on the first end of each of the plurality of relay fluid circulation lines to connect respective fluid circulation lines to respective relay fluid circulation lines, and
• wherein, in other than the first connection combination, the plurality of interference components prevent connecting at least one of the plurality of fluid circulation lines to at least one of the plurality relay fluid circulation lines.
