Patent ID: 7883489

Claim:
A device for irrigating and pressurizing an organ cavity, said device comprising: at least one source of pressurized fluid; a circuit of pipes formed from the at least one source of pressurized fluid; a supply pipe connected to said circuit of pipes, said supply pipe opening at its downstream end into said cavity; a discharge pipe for said fluid re-emerging from said cavity; and a regulating means for regulating said fluid; said regulating means comprising a first pumping means designed to engage and disengage the supply pipe and a second pumping means designed to engage the discharge pipe, wherein said first pumping means includes a peristaltic pump and means for neutralizing the pumping effect on the supply pipe so that the peristaltic pump does not pump fluid in the supply pipe, said neutralizing means comprising a retractable shoe mobile between a position in engagement with the supply pipe and a position retracted from the supply pipe, and wherein said first and second pumping means are successively arranged in (i) a first position in which said first pumping means is disengaged from the supply pipe and the neutralizing means neutralizes the pumping effect on the supply pipe so that the first pumping means does not pump fluid, and said second pumping means is activated at a first speed and engages the discharge pipe so that the second pumping means pumps fluid, and (ii) a second position in which said first and second pumping means are activated at a same speed higher than the first speed and in the same direction and are both engaged with their respective pipes so that both the first and second pumping means pump fluid.
