Patent ID: 7371224

Claim:
A device for rinsing a body cavity with a fluid comprising: a rinse pump operative to introduce fluid into a body cavity through a channel, a pressure sensor on a pressure side of the rinse pump and upstream of an outlet of the channel; means for inserting a medical instrument into the body cavity, the medical instrument comprising means for establishing fluid communication with the body cavity; a suction pump in fluid communication along a first pathway with the fluid communication establishing means and along a second pathway with the body cavity; a T piece and a first, a second, and a third hose connected to outlets of the T piece, the first pathway comprising the first hose connected to an outlet of the medical instrument, the second pathway comprising the second hose, and the third hose connected to the suction pump; means for controlling fluid flow along the second pathway; a T piece positive locking cutout having a recess adapted to positively lock the T piece thereinto, the T piece positive locking cutout integrally formed with the fluid flow controlling means; and a control unit in signal communication with the rinse pump, the pressure sensor, the suction pump, and the fluid flow controlling means, for receiving pressure values from the pressure sensor and for controlling the rinse pump, the suction pump, and the fluid flow controlling means in response to the received pressure values, operative to control fluid flow through the body cavity depending on received pressure changes caused by changes in an operating condition of the medical instrument according to a preset volume flow of at least one of the rinse pump and the suction pump and according to a predetermined required pressure.
