Abstract
A hybrid apparatus for delivery of fluid in connection with endoscopic irrigation and lens cleaning including a connector which is adaptable to a flexible or rigid container, a connector arranged at the end thereof and connected via a tubing supply to a fluid, air and or gas source and to an endoscope during a procedure.
Claims20
An apparatus, comprising:
- a cap configured to be coupled to a fluid source, the fluid source defining a chamber configured to contain a fluid;
- a first tube coupled to the cap such that a lumen defined by the first tube is in fluid communication with the chamber of the fluid source when the cap is coupled to the fluid source, the first tube configured to fluidically couple a gas source to the chamber of the fluid source;
- a second tube configured to extend through a first opening in the cap such that, when the cap is coupled to the fluid source, at least a portion of the second tube is received in the chamber of the fluid source and an end of the second tube is disposed in the fluid therein, the second tube configured to convey fluid out of the chamber of the fluid source to an endoscope;
- a third tube configured to extend through a second opening in the cap such that, when the cap is coupled to the fluid source, at least a portion of the third tube is received in the chamber of the fluid source and an end of the third tube is disposed in the fluid therein, the third tube configured to convey fluid out of the chamber of the fluid source to the endoscope;
- a first check valve coupled to the second tube and configured to prevent the flow of fluid from the second tube into the chamber of the fluid source when fluid is conveyed out of the chamber of the fluid source to the third tube;
- and
- a second check valve coupled to the third tube and configured to prevent the flow of fluid from the endoscope into the chamber of the fluid source,
- wherein the second tube is configured to convey the fluid from the fluid source to the endoscope during a first time period, the third tube is configured to convey the fluid from the fluid source to the endoscope during a second time period, at least a portion of the second time period is concurrent with at least a portion of the first time period.

A apparatus for delivering fluid to an endoscope, comprising:
- a cap assembly including a cap configured to be coupled to a fluid source, the cap assembly defining a first lumen configured to convey gas from a gas source into a chamber of the fluid source sufficient to increase a pressure within the chamber of the fluid source, a second lumen configured to convey the fluid out of the chamber of the fluid source responsive to the increased pressure within the chamber of the fluid source, and a third lumen configured to convey the fluid out of the chamber of the fluid source;
- and
- a valve assembly including a first check valve configured to prevent the flow of fluid from the second lumen of the cap assembly into the chamber of the fluid source, the valve assembly further including a second check valve configured to prevent the flow of fluid from the endoscope into the chamber of the fluid source,
- wherein fluid can be conveyed from the chamber of the fluid source through each of the second lumen and the third lumen substantially simultaneously.
1 more element
An apparatus for delivering liquid to an endoscope, the apparatus comprising:
- a connector configured to be coupled to a container, the container defining an inner volume and configured to contain a liquid;
- a first tube coupled to the connector and configured to fluidically couple a gas source to the inner volume of the container;
- a second tube coupled to the connector and configured to fluidically couple and convey the liquid contained in the inner volume of the container to the endoscope during a first time period, the second tube having a first end and a second end and defining a lumen therebetween, the first end of the second tube configured to be coupled to the endoscope and the second end of the second tube configured to be disposed in the liquid contained in the inner volume of the container, the second tube including a first check valve configured to prevent the flow of liquid from the lumen of the second tube into the inner volume of the container;
- and
- a third tube coupled to the connector and configured to fluidically couple and convey the liquid contained in the inner volume of the container to the endoscope during a second time period, the third tube having a first end and a second end and defining a lumen therebetween, the first end of the third tube configured to be coupled to the endoscope and the second end of the third tube configured to be disposed in the liquid contained in the inner volume of the container, the third tube including a second check valve configured to prevent the flow of liquid from the endoscope into the third tube,
- wherein at least a portion of the second time period is concurrent with at least a portion of the first time period.
