Abstract

The present specification describes a jet distributor provided to supply fluids to each of a plurality of jet openings in a multi jet endoscope tip. In an embodiment, the jet distributor is supplied with a fluid from a jet pump. The jet distributor includes at least two fluid channels to provide the fluid supplied via the jet pump to the front-jet, right-side-jets and left-side-jets in the endoscope tip. The jet-distributor includes a motor which rotates a rotating plug. The rotating plug includes an internal fluid pathway which becomes intermittently aligned with each of a plurality of fluid output channels in the jet distributor as the plug rotates, thereby providing fluid in a successive manner to the jets in the endoscope tip.

Claims

1. A system for distributing fluid from a source external to an endoscope into a plurality of fluid channels positioned within the endoscope, comprising:

a pump;

a fluid distributor device having a fluid input channel coupled to said pump, a distributor rotating plug and a plurality of fluid output channels, wherein said distributor rotating plug includes an internal fluid pathway, said internal fluid pathway being in fluid communication with said fluid input channel and capable of being positioned, via rotational movement of said distributor rotating plug, into a plurality of configurations wherein, when in each of said plurality of configurations, said internal fluid pathway is in fluid communication with one of said plurality of said fluid output channels and is not in fluid communication with any one of the remaining said plurality of fluid output channels;

a motor shaft coupled to said distributor rotating plug;

a motor coupled to said motor shaft, wherein, upon activating the motor, the motor causes the distributor rotating plug to rotate, thereby intermittently aligning said internal fluid pathway with each of said plurality of fluid output channels, allowing fluid to move from said fluid input channel, through the internal fluid pathway and successively into each of said plurality of fluid output channels; and

at least one endoscope connector comprising said plurality of endoscope fluid channels, wherein said plurality of endoscope fluid channels are in fluid communication with the plurality of fluid output channels.

2. The system of claim 1, further comprising a distributing element attached to said distributor rotating plug and rotatably movable within said fluid distributor device, wherein said distributing element comprises said internal fluid pathway.

3. The system of claim 1, further comprising a housing, wherein said housing comprises said fluid distributor device, said motor and said motor shaft.

4. The system of claim 3, wherein the housing further comprises a locking element for fixedly positioning the fluid distributor device within the housing.

5. The system of claim 4, wherein the fluid distributor device further comprises a groove on an outer surface of said fluid distributor device for receiving the locking element.

6. The system of claim 1, wherein the fluid distributor device is substantially cylindrical.

7. The system of claim 1, wherein the fluid distributor device comprises a housing having an external surface and wherein each of the plurality of fluid output channels extends outward from said external surface.

8. The system of claim 1, wherein the fluid distributor device comprises at least three fluid output channels and wherein each of said at least three fluid output channels is separately and individually connected to at least three endoscope fluid channels.

9. The system of claim 1, wherein said at least one endoscope connector is positioned within said endoscope.

10. The system of claim 1, wherein said at least one endoscope connector is positioned within a main control unit external to said endoscope.

11. The system of claim 10, wherein said at least one endoscope connector comprises a plurality of connectors for connecting said plurality of endoscope fluid channels with said plurality of fluid output channels.

12. The system of claim 10, wherein said at least one endoscope connector comprises a single connector for connecting said plurality of endoscope fluid channels with said plurality of fluid output channels.

13. The system of claim 1, wherein said distributor rotating plug has a distributor rate ranging between 30 revolutions per minute (rpm) and 100 rpm.
