Abstract

A device for rinsing a body cavity with a fluid includes a rinse pump for introducing fluid into a body cavity and a pressure sensor on a pressure side of the rinse pump. A medical instrument insertable into the body cavity is adapted to establish fluid communication with the body cavity. A suction pump is in fluid communication along a first pathway with the medical instrument and along a second pathway with the body cavity. Fluid flow along the second pathway is controllable. A control unit receives pressure values from the pressure sensor, controls the rinse pump, the suction pump, and the flow controller in response to received pressure values, and is thus operative to control fluid flow through the body cavity depending on an operating condition of the medical instrument.

Claims

1. A device for rinsing a body cavity with a fluid comprising:

a rinse pump for introducing fluid into a body cavity;

a pressure sensor on a pressure side of the rinse pump;

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 establishing means and along a second pathway with the body cavity;

means for controlling fluid flow along the second pathway; and

a control unit in signal communication with the rinse pump, the pressure sensor, the suction pump, and the flow controlling means, for receiving pressure values from the pressure sensor and for controlling the rinse pump, the suction pump, and the flow controlling means in response to the received pressure values, operative to control fluid flow through the body cavity depending on an operating condition of the medical instrument.
