Devices, systems, and methods to supply fluids to an endoscope

A fluid supply system for an endoscope system, the fluid supply system comprising:

• a container configured to contain fluid;
• a manifold comprising:
• a pressurized gas pathway;
• a first fluid pathway configured to receive fluid from the container;
• a second fluid pathway configured to receive fluid from the container;
• a first port in fluid communication with the pressurized gas pathway;
• a second port in fluid communication with the first fluid pathway;
• a third port in fluid communication with the second fluid pathway;
• a first bag spike configured to engage the container and in fluid communication with the pressurized gas pathway to provide pressurized gas to the container;
• and
• a second bag spike configured to engage the container and in fluid communication with the first fluid pathway and the second fluid pathway;
• a first tubing set having a first end configured to couple to the second port and to be in communication with a pump;
• and
• a second tubing set having a first end configured to couple to the third port and to be in fluid communication with an endoscope of the endoscope system.

A manifold for use with an endoscope system, the manifold comprising:

• an irrigation conduit configured to be in fluid communication with a source of fluid;
• a lens wash chamber configured to receive liquid from the irrigation conduit via an inlet and output the liquid received from an outlet;
• a pressurized chamber configured to receive pressurized gas;
• and
• an adjustable barrier between the pressurized chamber and the lens wash chamber,
• wherein the adjustable barrier comprises a plunger configured to form a seal with a wall defining the pressurized chamber and the lens wash chamber, and
• wherein the adjustable barrier is configured to adjust to push liquid through the outlet in response to the pressurized chamber receiving the pressurized gas.
