Claims29
A method, comprising:
- coupling a fluid transfer device to a fluid source, the fluid source defining a chamber configured to contain a liquid;
- conveying gas through a first tube from a gas source to the chamber of the fluid source;
- conveying through a second tube including a first check valve, during a first time period, a first volume of the liquid out of the chamber of the fluid source to an endoscope at a first flow rate in response to the conveying of gas to the chamber of the fluid source;
- and
- conveying through a third tube including a second check valve, during a second time period, a second volume of the liquid out of the chamber of the fluid source to the endoscope at a second flow rate, the second flow rate different than the first flow rate,
- wherein at least a portion of the second time period is concurrent with at least a portion of the first time period.

A method, comprising:
- coupling a fluid transfer device to a fluid source, the fluid source defining a chamber configured to contain a liquid;
- conveying gas from a gas source through a first tube to the chamber of the fluid source;
- conveying, during a first time period, a first volume of the liquid out of the chamber of the fluid source via a second tube coupled to a cap, the chamber of the fluid source being sealed by the cap, the second tube including a first check valve and configured to convey the liquid from the chamber of the fluid source to an endoscope for cleaning of an endoscopic lens;
- and
- conveying, during a second time period, a second volume of the liquid out of the chamber of the fluid source via a third tube coupled to the cap, the third tube including a second check valve and configured to convey the liquid from the chamber of the fluid source to the endoscope for endoscopic irrigation,
- wherein at least a portion of the second time period is concurrent with at least a portion of the first time period.

A method of transferring a liquid from a fluid source to a medical device using a fluid transfer device, the fluid transfer device including a gas tube, a first liquid tube, and a second liquid tube, the method comprising:
- conveying gas through the gas tube from a gas source to the fluid source;
- conveying the liquid from the fluid source through the first liquid tube to the medical device during a first time period;
- conveying the liquid from the fluid source through the second liquid tube to the medical device during a second time period;
- conveying from the fluid source through the first liquid tube and through the second liquid tube to the medical device concurrently during a third time period;
- and
- preventing via check valves the liquid from flowing from the medical device through the first tube and through the second tube to the fluid source.
