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 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;

at least one 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; and

a control unit comprising separate control elements for operating the at least one pump for irrigation and for inflation and/or deflation of the retention member, respectively, wherein said control elements are operable independently of each other.

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

3. The irrigation system of claim 1, wherein the at least one pump comprises a manually operated pump, such as a bulb or a bellow 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 at least one pump comprises a powered pump, such as an electrically or pneumatically operated 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 separate pumps are provided for transferring of irrigating liquid from the reservoir to the probe for irrigation and for inflation of the inflatable retention member, respectively.

8. The irrigation system of claim 1, wherein at least one of the pump(s) is integrated in the control unit.

9. 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.

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

11. The irrigation system of claim 1, wherein a 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 on the probe.

12. The irrigation system of claim 11, wherein a single pump is an electrical pump.

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

14. The irrigation system of claim 1, wherein at least one of the control elements for controlling said pump(s) function 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.

15. Use of the irrigation device according to claim 1 for rectal irrigation.
