Abstract

A cleansing system for the intestine of a patient includes a pumping system adapted to provide pulses of a cleansing fluid at a controlled rate and an annular fluid channel in fluid communication with the pumping system. The annular fluid channel serves as a fluid conduit between the body cavity to be cleansed and the exterior of the body. A delivery system includes a nozzle assembly, the nozzle assembly having at least two lumens through which the cleansing fluid exits the nozzle assembly, the at least two lumens being arranged at an angle relative to the annular fluid channel.

Claims

1. A cleansing system for the intestine of a patient, the system comprising:

a pumping system adapted to provide pulses of a cleansing fluid at a controlled rate;

an annular fluid channel in fluid communication with the pumping system, the annular fluid channel serving as a fluid conduit between the body cavity to be cleansed and the exterior of the body; and

a delivery system including a nozzle assembly, the nozzle assembly having at least two lumens through which the cleansing fluid exits the nozzle assembly, the at least two lumens being arranged at an angle relative to the annular fluid channel.

2. The cleansing system of claim 1 wherein the pumping system comprises a peristaltic pump.

3. The cleansing system of claim 1, and further comprising an additional lumen within the nozzle to act as a condui9t through which to monitor the internal pressure of the body cavity of the patient.

4. The cleansing system of claim 1 wherein the nozzle assembly comprises

a nozzle body housing a nozzle body cavity;

an inlet port in fluid communication with the nozzle body cavity;

an annular fluid channel in fluid communication with the nozzle body cavity; and

a nozzle tip having at least two lumens in fluid communication with the fluid channel.

5. The cleansing system of claim 4 wherein the at least two lumens comprises three lumens arranged at an angle relative the annular fluid channel.

6. The cleansing system of claim 4 wherein the at least two lumens comprises two lumens arranged at an angle relative the annular fluid channel.

7. The cleansing system of claim 4 wherein the at least two lumens comprises four lumens arranged at an angle relative the annular fluid channel.

8. The cleansing system of claim 4 wherein the nozzle body and nozzle body cavity are formed by the interconnection of a transition hub and a transition hub cap.

9. The cleansing system of claim 4 wherein the annular fluid channel is formed between an inner nozzle tube and an outer nozzle tube in coaxial arrangement.

10. A nozzle assembly comprising

a nozzle body housing a nozzle body cavity;

an inlet port in fluid communication with the nozzle body cavity;

an annular fluid channel in fluid communication with the nozzle body cavity;

a nozzle tip having at least two lumens in fluid communication with the fluid channel and arranged at an angle relative the annular fluid channel.

11. The nozzle assembly of claim 10 wherein the at least two lumen comprises three lumens.

12. The nozzle assembly of claim 10 wherein the at least two lumens comprises two lumens.

13. The nozzle assembly of claim 10 wherein the at least two lumens comprises four lumens.

14. The nozzle assembly of claim 10 wherein the nozzle body and nozzle body cavity are formed by the interconnection of a transition hub and a transition hubcap.

15. The nozzle assembly of claim 10 wherein the annular fluid channel is formed between an inner nozzle tube and an outer nozzle tube in coaxial arrangement.

16. A nozzle assembly comprising

a nozzle body housing comprising a transition hub and a transition hubcap connected to form a nozzle body cavity;

an inlet port in fluid communication with the nozzle body cavity;

an annular fluid channel in fluid communication with the nozzle body cavity, the annular fluid channel being formed between an inner nozzle tube and an outer nozzle tube in coaxial arrangement; and

a nozzle tip having at least two lumens in fluid communication with the fluid channel, and arranged at an angle relative to the annular fluid channel..

17. The nozzle assembly of claim 16 wherein the at least two lumens comprises three lumens.

18. The nozzle assembly of claim 16 wherein the at least two lumens comprises two lumens.

19. The nozzle assembly of claim 16 wherein the at least two lumens comprises four lumens.

20. A method for cleansing a stoma comprising:

providing a cleansing fluid stream to a nozzle assembly, the nozzle assembly having a central axis;

pulsing the cleansing fluid stream; and

discharging the pulsed fluid stream from the nozzle assembly through at least two lumens being arranged at an angle to the axis of the nozzle, to discharge the pulsed fluid stream at an angle relative to the annular fluid channel.

21. The method of claim 20 further including monitoring the cleansing fluid stream pressure.
