## Abstract

An irrigation system is disclosed that can be uses in, for example, rectal irrigation. The system comprises a reservoir for an irrigating liquid and a probe for arrangement in a user. The probe includes an inflatable balloon for fixing the catheter in a body cavity. A first pump is provided to pump irrigation liquid from the reservoir to the probe, and a second pump is provided to pump a fluid to the balloon for inflation. A control unit controls the transfer of the irrigation liquid and the fluid, and includes a valve for releasing fluid from the balloon for deflation. Tubing provides fluid communication between the reservoir, control unit and probe. The control unit and the first and second pumps are further arranged as an integrated unitary component, and the manually operable balloon control element is arranged in the vicinity of the second pump.

## Claims

### Claim 1

An irrigation system, comprising:
a reservoir for an irrigation liquid;
a probe for arrangement in a user, wherein said probe comprises an inflatable balloon for fixing the probe in a body cavity;
a first pump configured to directly or indirectly pump the irrigation liquid from the reservoir to the probe;
a second pump to pump a fluid to the balloon for inflation;
a control unit to control the transfer of said irrigation liquid and said fluid, wherein said control unit further comprises a valve for releasing fluid from the balloon for deflation, said valve being provided with a manually operable balloon control element, wherein said control unit and said first and second pumps are arranged as an integrated unitary component, and wherein the control unit comprises a housing that is in direct physical contact with the first pump and the second pump; and
tubing arranged to provide fluid communication between said reservoir and said integrated unitary component, and between said integrated unitary component and said probe;
wherein said manually operable balloon control element is arranged in a vicinity of the second pump.

### Claim 2 (depends on 1)

The irrigation system of claim 1, wherein the first pump is arranged to directly pump irrigation liquid from the reservoir to the probe.

### Claim 3 (depends on 1)

The irrigation system of claim 1, wherein the first pump is arranged to pump a gas into the reservoir to create a pressure in the reservoir to displace the irrigation liquid therefrom and feed it to the probe.
