First Claim
1. A device for irrigation of, and aspiration from, a body cavity, the device comprising:
- a delivery pump formed as a peristaltic/roller pump;
a suction pump formed as a peristaltic/roller pump;
a delivery pump shaft and a suction pump shaft, said delivery pump shaft and said suction pump shaft being arranged coaxially;
a first tubing line connected to said delivery pump and leading to the body cavity;
a second tubing line connected to said suction pump and leading to the body cavity;
switching means connected to said pump shafts and control means connected to said switching means for controlling the irrigation and aspiration of the body cavity.

Abstract
The present invention pertains to a device for irrigation of and aspiration from body cavities, especially during surgical laparoscopy, comprising a delivery pump and a suction pump and tubing lines, which are connected to these and lead to the body cavity. A device for irrigation of and aspiration from body cavities, which can be operated in a very simple manner and fully meets sterility requirements is provided. The suction pressure and the irrigation pressure can be finely controlled in a simple manner, a control device 1 for alternate irrigation of and aspiration from the body cavity is provided according to the present invention; the control device 1 is connected to a control line 3 and to a control valve 20 arranged in its path and controls the delivery and suction pumps 13 and 14 as a function of this control line, and the setting of the gas ballast in the control line 3 by means of the control valve 20 brings about control of the pressure and/or rotation speed of the delivery and suction pumps 13 and 14 (FIG. 2 l).
