Abstract

The present invention provides a gas water bottle adaptor that is suitable for attachment to a water bottle and to a bottle cap. The adaptor can include a gas inlet on one side thereof suitable for attachment to the gas connection of an endoscope. A sealing member can be affixed to the adaptor to prevent leakage of any fluid (e.g., liquid or gas) that is inside of the water bottle. The adaptor may be used in endoscopy methods and is particularly useful for adding a secondary gas source to a water bottle.

First claim

That which is claimed:

1. An adaptor for an endoscopic water bottle, the adaptor comprising:
a substantially tubular body having an interior surface and an exterior surface and having an upper body portion and a flared lower body portion, wherein the substantially tubular body is a one-piece structure;
the upper body portion having threads on the exterior surface thereof suitable for attachment to threads on a water bottle cap;
the flared lower body portion having threads on the interior surface thereof suitable for attachment to threads on a neck portion of the water bottle;
and comprising a gas inlet port extending outward from the exterior surface of the body and having a central passage extending through the body and opening on the interior surface of the body,
wherein the threads of the upper body portion are engageable with a thread configuration that is substantially identical to the threads of the flared lower body portion,
wherein the upper body portion includes a groove on the exterior surface, and
wherein the adaptor further comprises a sealing member associated with the exterior surface of the upper body portion, in which the sealing member is seated in the groove for forming a fluid tight seal between the adaptor and the water bottle cap.

2. The adaptor of claim 1 , wherein the threads of the lower body portion are disposed on a first side of the threads of the upper body portion, and wherein the groove is formed on a second side of the threads of the upper body portion that is opposite the first side of the upper body portion.

3. The adaptor of claim 1 , further comprising a sealing member associated with the interior surface of the flared lower body portion for forming a fluid tight seal between the adaptor and the water bottle.

4. The adaptor of claim 1 , further comprising a substantially horizontal ledge on the interior surface of the body that delineates the interior surface of the upper body portion from the interior surface of the lower body portion.

5. The adaptor of claim 1 , wherein an interior diameter of the upper body portion is less than an interior diameter of the lower body portion.

6. The adaptor of claim 1 , wherein the adaptor further comprises a component for closing the gas inlet port to fluid passage.

7. The adaptor of claim 1 , wherein the gas inlet port comprises a luer connector.

8. The adaptor of claim 1 , wherein the adaptor body and gas inlet port are a one-piece structure.

9. The adaptor of claim 1 , wherein the adaptor provides an open interior passage between a water bottle affixed to the lower body portion and a water bottle cap affixed to the upper body portion.

10. The adaptor of claim 1 , wherein the gas inlet port is positioned such that an opening on the interior surface of the body is located between the threads on the upper body portion and the threads on the lower body portion.

11. The adaptor of claim 1 , wherein the adaptor is a machined part or a molded part.

12. The adaptor of claim 1 , wherein the adaptor is single-use or reusable.

13. The adaptor of claim 1 , wherein the adaptor body comprises a metal material.

14. The adaptor of claim 1 , wherein the adaptor is a step-up or step-down convertor.
