This disclosure relates generally to a container and tube set and methods for fluid delivery, and particularly an integrated container and tube set suitable for use with an endoscope to supply liquids and/or gases to the endoscope. The integrated container and tubes may include a container (e.g., water reservoir) containing a fluid and a gas, and a plurality of tubes integrally formed with the container. The integrated container may include an irrigation supply tube having a first lumen in fluid communication with the fluid, a lens wash supply tube having a second lumen in fluid communication with the fluid, a gas supply tube having a third lumen in operative communication with the gas, and an optional alternative gas supply tube having a fourth lumen in fluid communication with the gas. The lens wash supply tube and the gas supply tube may be formed as a single, multi-lumen tube.

An endoscope including a first substantially hollow cylindrical body and a second substantially hollow cylindrical body, wherein the first body and the second body at least partially overlap coaxially, and wherein between the first body and the second body a round cord seal is disposed, which is sealingly disposed between a first sealing surface of the first body and a second sealing surface of the second body. Wherein, the first sealing surface is conical.

Various implementations include an insufflation system for use with an endoscope. The insufflation system includes a housing, a CO.sub.2 system, a water system, a foot pedal, a control system, an aromatic dispersion system, an audio system, and a water tubing valve. Various implementations also include a more visible foot pedal, which is useful in difficult-to-see environments. In some implementations, a water tubing valve couples conduits from two water containers to the endoscope. In a first position, water flows only from a first water container. In a second position, water flows only from a second water container. The water tubing valve prevents water-flow from both of the first water container and the second water container to happen simultaneously. The water tubing valve allows for an operator to quickly switch a source of the water, thereby facilitating continuation of a procedure in a case that the first water container is fully depleted.

In at least some aspects, an instrument port for introducing an instrument into a surgical site comprises: a port body having: an instrument channel extending through the port body; and a plurality of fluid flush channels each separate from one another and the instrument channel, each extending along a major portion of the port body and in fluid communication with the instrument channel; and a bulb comprising a bulb channel extending through the bulb, the bulb channel aligned with the instrument channel, wherein the bulb channel and instrument channel are configured to receive the instrument.

Provided is a multifunctional connector. The multifunctional connector includes an auxiliary conduit which is branched from a main conduit and has a guide portion; and an operation member provided detachably from the auxiliary conduit, wherein the operation member includes an intubation portion inserted into the auxiliary conduit; sliding guide formed to move forward and backward while being guided by the guide portion; a fixing cap fixing the sliding guide so as not to be separated from the guide portion; and a first port through which a fluid is injected or discharged, thereby improving the efficiency of treatment, mitigating the fatigue of medical staffs, and reducing contamination of affected areas and a risk of damage to tissues around an endoscope.

Some implementations of the disclosure relate to an endoscope, comprising: a shaft comprising: a distal end; and a proximal end comprising a rigid attachment segment configured to be removably coupled to an adapter or instrument, a surface of the rigid attachment segment comprising: a groove and a section adjacent the groove, the section protruding relative to the groove and comprising a recessed indentation or protrusion; and a housing coupled to the shaft. The surface of the rigid attachment segment may include multiple grooves and multiple sections alternating along the longitudinal length of the rigid attachment segment; each of the sections protrudes relative to the grooves and comprises a recessed indentation or protrusion; and the multiple sections and the multiple grooves are configured such that the instrument or the adapter can be coupled to the endoscope in a plurality of lengthwise positions.

Various embodiments are generally directed to fluid container adapters that couple with a fluid container, so to enable access to the contents of the fluid container, such as from an endoscopic system via a tubing set. Several embodiments are particularly directed to a fluid container adapter that can couple with an opening in a variety of fluid containers to place one or more tubes in fluid communication with an interior of any particular one of the variety of fluid containers.

Various embodiments are generally directed to fluid container enclosure systems that couple with a fluid container and enable different systems, such as endoscopic systems, to access the contents of the fluid container, such as via a tubing set. The enclosure systems are configured to fit a wide range of fluid container necks, ports, or other openings, including various opening dimensions, thread finishes, and/or thread dimensions. In one embodiments, an enclosure system may include a cap having multiple carriages arranged therein. For example, a primary carriage may be arranged within the cap to engage with larger-dimensioned bottles. A secondary carriage may be arranged to float within the primary carriage to engage smaller-dimensioned bottles that bypass the primary carriage. Other embodiments are described.

Various embodiments are generally directed to fluid container enclosure systems that couple with a fluid container and enable different systems, such as endoscopic systems, to access the contents of the fluid container, such as via a tubing set. The enclosure systems are configured to fit a wide range of fluid container necks, ports, or other openings, including various opening dimensions and thread finishes. In one embodiment, an enclosure system may include a plug having a sleeve extending therefrom. The plug may be deformed manually or via a plunger system to reduce the outer dimension thereof to fit the plug in the neck of a fluid container. Once the plug is arranged within the neck, the sleeve may be folded down over an outer surface of the neck to form or reinforce a seal between the enclosure system and the neck of the fluid container. Other embodiments are described.
