Abstract

An irrigation system, useable e.g. for rectal/anal irrigation, comprising a reservoir for irrigating liquid; a probe (such as a catheter) for arrangement in a user, and having an inflatable retention member (such as a balloon); and tubing providing fluid communication between the reservoir, the control unit and the probe for conducting the irrigation fluid from the reservoir to the probe.

Claims

1. An irrigation system comprising:

a reservoir for irrigating liquid;

a control unit;

a probe for arrangement in a user, and having an inflatable retention member;

tubing providing fluid communication between said reservoir, control unit and probe for conducting the irrigation fluid from the reservoir to the probe; and

a single pump provided for pumping gas into the reservoir to transfer the irrigating liquid from the reservoir to the probe for irrigation and for inflation of the inflatable retention member, wherein the single pump is useable both for pumping irrigation liquid for discharge through the probe and for pumping a fluid for filling of the inflatable retention member;

wherein the control unit comprises separate control elements, a first control element for operating the pump for irrigation and a second control element for inflation and/or deflation of the retention member, respectively, wherein said control elements are operable independently of each other such that the inflation and/or deflation of the retention member takes place independently or simultaneously as the irrigation.

2. The irrigation system of claim 1, wherein the control elements are operable by of depression, twisting, rotating, pulling and pushing.

3. The irrigation system of claim 1, wherein the pump is a manually operated pump.

4. The irrigation system of claim 3, wherein the manually operated pump is a bulb or a bellow pump.

5. The irrigation system of claim 1, wherein the pump comprises a powered pump.

6. The irrigation system of claim 5, wherein the powered pump is an electrically or pneumatically operated pump.

7. The irrigation system of claim 1, wherein the pump is integrated in the control unit.

8. The irrigation system of claim 1, wherein the tubing includes a first part connecting the control unit with the probe and a second part connecting the reservoir with the control unit, and in which each of said first and second parts comprises a gas conducting tube and an irrigating liquid conducting tube.

9. The irrigation system of claim 1, wherein the control unit comprises separate control elements for inflation and deflation, respectively, of the inflatable retention member.

10. The irrigation system of claim 1, wherein a single pump is an electrical pump.

11. The irrigation system of claim 1, wherein the control unit further comprises a display.

12. The irrigation system of claim 11, wherein the display is a touchscreen.

13. The irrigation system of claim 1, wherein the pump comprises an electrical pump and of the control elements for controlling said pump functions as a dead man'"'"'s handle, thereby immediately returning to a deactivated state, in which the electrical pump is controlled not to pump, when manual operation of the control element is aborted.

14. The irrigation system of claim 1, wherein said control elements are operable simultaneously to enable simultaneous transfer of irrigating liquid from the reservoir to the probe for irrigation and inflation or deflation of the inflatable retention member.

15. The irrigation system of claim 1, wherein components of the system are individually exchangeable.

16. The irrigation system of claim 1, further comprising a battery, wherein the battery in inductively chargeable.

17. The irrigation system of claim 1, wherein the control unit further comprises a separate wired or wireless control and wherein the separate control is a remote control for the irrigation system.

18. The irrigation system of claim 17, wherein the remote control is one of a phone, tablet computer or laptop computer.

19. The irrigation system of claim 1, wherein the control unit is programmable to automatically carry out a predefined program.

20. The irrigation system of claim 1, wherein the control unit transmits operation data to a remote unit for analysis.
