Flow control for endoscope fluid supply

A container and tube set arranged and configured to couple to an endoscope for use in an endoscopic procedure, the container and tube set comprising:

• a first container configured to contain a fluid, the first container having a port in fluid communication with a bottom portion thereof;
• a first water supply tube including a first end, a second end, and a first lumen extending therethrough, wherein the first lumen is in fluid communication with the first container and the second end of the first water supply tube is positioned external to the first container;
• a branched connector positioned in line with the first water supply tube between the first and second ends thereof, the branched connector including a first fluid inlet, a first fluid outlet, and a second fluid outlet, a portion of the first lumen of the first water supply tube extending between the first fluid inlet and the first fluid outlet;
• a second container configured to contain a fluid, the second container having a second fluid inlet in selective fluid communication with the second fluid outlet of the branched connector;
• a second water supply tube including a first end, a second end, and a second lumen extending therethrough, wherein the second lumen is in selective fluid communication with the bottom portion of the second container and the second end of the second water supply tube is positioned external to the second container;
• a first gas supply tube including a first end, a second end, and a third lumen extending therethrough, wherein the third lumen is in operative fluid communication with the second container and the second end of the first gas supply tube is positioned external to the second container;
• and
• a flow control valve in fluid communication with the second water supply tube and the first gas supply tube, the flow control valve configured to obstruct flow through the second water supply tube when water pressure at the flow control valve is below a threshold pressure.

An endoscopic surgical device, comprising:

• an endoscopic probe;
• a container and tube set coupled to the endoscopic probe, the container and tube set comprising:
• a first container configured to contain a fluid, the first container having a port in fluid communication with a bottom portion thereof,
• a first water supply tube including a first end, a second end, and a first lumen extending therethrough, wherein the first lumen is in fluid communication with the first container and the second end of the first water supply tube is positioned external to the first container,
• a branched connector positioned in line with the first water supply tube between the first and second ends thereof, the branched connector including a first fluid inlet, a first fluid outlet, and a second fluid outlet, a portion of the first lumen of the first water supply tube extending between the first fluid inlet and the first fluid outlet,
• a second container configured to contain a fluid, the second container having a second fluid inlet in selective fluid communication with the second fluid outlet of the branched connector,
• a second water supply tube including a first end, a second end, and a second lumen extending therethrough, wherein the second lumen is in selective fluid communication with the bottom portion of the second container and the second end of the second water supply tube is positioned external to the second container, and
• a flow control valve in fluid communication with the second water supply tube, the flow control valve configured to obstruct flow through the second water supply tube when water pressure at the flow control valve is below a threshold pressure.
