Abstract

Embodiments of the present invention provide water bottle cap assemblies suitable for attachment to an endoscopic device and a water source. For example, the water bottle cap assembly includes a cap comprising a plurality of ports and an engageable member configured to sealingly engage with a water source. The assembly also includes a plurality of tubular members, each tubular member coupled to a respective port so as to be in fluid communication therewith. In addition, the assembly includes an adaptor coupled to an end of one of the tubular members and configured to couple to an endoscopic device, wherein at least one of the tubular members is configured to convey at least one fluid between the water source and the endoscopic device.

Claims

1. A water bottle cap assembly for use with an endoscopic device, the assembly comprising:

a cap comprising a dome-shaped outer surface and an engageable member, wherein the engageable member is configured to sealingly engage with a water source, and wherein the dome-shaped outer surface defines a plurality of ports to allow for a plurality of output configurations that allow assembly of multiple different products all utilizing the same cap, wherein each of the plurality of ports are initially sealed via a removable sealing member to initially prevent fluid from flowing therethrough,

a plurality of tubular members, wherein each tubular member is coupled to a respective port so as to be in fluid communication therewith, wherein at least one of the tubular members being a single lumen tubular member comprising a coupling member for coupling to a gas supply unit;

an adaptor coupled to an end of one of the tubular members and configured to engage with an endoscopic device, at least one of the tubular members configured to convey at least one fluid between the water source and the endoscopic device; and

a filter disposed on the single lumen member and within 12 inches of the water source to filter contaminants from entering the water source and to prevent backflow to the gas supply unit, wherein the filter comprises pores of about 0.1 micron.

2. The water bottle cap assembly of claim 1, wherein the engageable member comprises internal threads.

3. The water bottle cap assembly of claim 1, further comprising a ring-shaped sealing member disposed within the cap and configured to facilitate engagement with the water source.

4. The water bottle cap assembly of claim 1, wherein the cap is configured to accommodate a volume of air between a maximum water level height and an interior of the dome-shaped outer surface of the cap.

5. The water bottle cap assembly of claim 1, further comprising a check valve disposed within at least one of the tubular members and configured to prevent fluid flow into the water source.

6. The water bottle cap assembly of claim 1, wherein the cap comprises two, three, or four ports.

7. The water bottle cap assembly of claim 1, wherein at least one of the tubular members comprises a dual-lumen tubular member such that an inner tube extends within an outer tube.

8. The water bottle cap assembly of claim 1, wherein at least one of the tubular members is configured to convey a gas source between the water source and the endoscopic device.

9. The water bottle cap assembly of claim 1, wherein at least one of the tubular members is configured to convey water between the water source and the endoscopic device for irrigation.

10. The water bottle cap assembly of claim 1, wherein the water bottle cap assembly is formed of a sterilizable polymeric material and is disposable.

11. The water bottle cap assembly of claim 1, wherein the filter is a hydrophobic filter.

12. A water bottle cap assembly for use with an endoscopic device, the assembly comprising:

a cap comprising an engageable member configured to sealingly engage with a water source, wherein the cap defines four ports, the four ports opening into a fluid storage chamber defined by the water source and the cap,

the fluid storage chamber configured to accommodate a volume of air between a maximum water level height of the water source and an interior of the cap, wherein each of the four ports is initially sealed off with a removable sealing member to prevent fluid through the associated port, and wherein each of the removable sealing members comprise at least one of a peelable material and a pierceable material,

a plurality of tubular members, each tubular member coupled to a respective port so as to be in fluid communication therewith, at least one of the tubular members being a single lumen tubular member comprising a coupling member configured to couple to a gas supply unit;

an adaptor coupled to an end of one of the tubular members and configured to engage with an endoscopic device, at least one of the tubular members configured to convey at least one fluid between the water source and the endoscopic device; and

a filter disposed on the single lumen member and within 12 inches of the water source to filter contaminants from entering the water source and to prevent backflow to the gas supply unit, wherein the filter comprises pores of about 0.1 micron,

wherein the volume of air allows a pressure level of the water source to be increased to a level sufficient for conveying the at least one fluid from the water source through at least one of the tubular members.

13. The water bottle cap assembly of claim 12, wherein the cap comprises a dome-shaped outer surface.

14. The water bottle cap assembly of claim 12, wherein at least one of the tubular members is configured to convey water between the water source and the endoscopic device for irrigation.

15. The water bottle cap assembly of claim 12, wherein the filter is a hydrophobic filter.
