Abstract

Medical devices and methods for using medical devices are disclosed. Example fluid reservoirs and tube sets arranged and configured to couple to an endoscope for use in an endoscopic procedure are disclosed. An example fluid reservoir and tube set includes a fluid reservoir configured to contain a fluid, a fluid supply tube configured to be coupled to the endoscope and having a lumen extending therethrough, wherein the lumen is in fluid communication with the fluid reservoir and a first backflow prevention mechanism coupled to the fluid supply tube, the first backflow prevention mechanism configured to permit fluid to flow through the fluid supply line from the fluid reservoir to the endoscope and to prevent fluid from flowing back through the fluid supply tube from the endoscope to the fluid reservoir.

Claims (18)

1 . A fluid reservoir and tube set arranged and configured to couple to an endoscope for use in an endoscopic procedure, the fluid reservoir and tube set comprising:

a fluid reservoir configured to contain a fluid;

a fluid supply tube configured to be coupled to the endoscope and having a lumen extending therethrough, wherein the lumen is in fluid communication with the fluid reservoir; and

a first backflow prevention mechanism coupled to the fluid supply tube, the first backflow prevention mechanism configured to permit fluid to flow through the fluid supply tube from the fluid reservoir to the endoscope and to prevent fluid from flowing back through the fluid supply tube from the endoscope to the fluid reservoir,

wherein the first backflow prevention mechanism includes a clamp positioned adjacent to the fluid supply tube.

2 . The fluid reservoir and tube set of claim 1 , wherein the fluid supply tube is configured to permit fluid to flow from the fluid reservoir to a lens of the endoscope.

3 . The fluid reservoir and tube set of claim 1 , wherein the first backflow prevention mechanism further includes a portion of the fluid supply tube, wherein the portion of the fluid supply tube is configured to shift between a radially closed configuration and a radially open configuration.

4 . The fluid reservoir and tube set of claim 3 , wherein when in the closed configuration, the portion of the fluid supply tube is configured to prevent fluid from flowing through the fluid supply tube from the endoscope to the fluid reservoir.

5 . The fluid reservoir and tube set of claim 4 , further comprising a gas supply tube, the gas supply tube including a first end and a second end, the first end configured to be coupled to a gas pump, and the second end positioned within the fluid reservoir, and wherein the gas supply tube is configured to permit gas to flow into and pressurize the fluid in the fluid reservoir.

6 . The fluid reservoir and tube set of claim 5 , wherein the portion of the fluid supply tube is configured to shift from the closed configuration to the open configuration in response to the pressurized fluid flowing through the fluid supply tube.

7 . The fluid reservoir and tube set of claim 3 , wherein the portion of the fluid supply tube includes an elongate cross-sectional shape in the closed configuration.

8 . The fluid reservoir and tube set of claim 3 , wherein the portion of the fluid supply tube includes a circular cross-sectional shape in the closed configuration.

9 . The fluid reservoir and tube set of claim 1 , wherein the first backflow prevention mechanism further includes an elastic section of material.

10 . The fluid reservoir and tube set of claim 1 , wherein the clamp is configured to squeeze the fluid supply tube to prevent from flowing back through the fluid supply tube from the endoscope to the fluid reservoir.

11 . The fluid reservoir and tube set of claim 10 , wherein the clamp is configured to open in response to pressurized fluid flowing through the fluid supply tube.

12 . The fluid reservoir and tube set of claim 11 , wherein the clamp is attached to the fluid reservoir.

13 . The fluid reservoir and tube set of claim 1 , further comprising an irrigation supply tube including a first end, a second end, and a lumen extending therethrough, the lumen of the irrigation supply tube being in fluid communication with the fluid reservoir.

14 . The fluid reservoir and tube set of claim 13 , further comprising a second backflow prevention mechanism coupled to the irrigation supply tube, the second backflow prevention mechanism configured to permit fluid to flow through the irrigation supply tube from the fluid reservoir to the endoscope, and to prevent fluid from flowing back through the irrigation supply tube from the endoscope to the fluid reservoir.
