co2-aqua-purator for the operative laparoscopy for irrigation of the abdominal cavity with physiological naclsolution. • The unit working with CO2-gas, allows for infinitely variable adjustment of the instillation pressure from 0 to 750 mmhg. • The instillation quantity can be preselected to 1 l/min and hi-Flo 3 l/min depending on the instillation pressure (max. 750 mmhg). • large reserve of irrigation liquid by two NaCl bottles. • Contamination-free waste management of liquid by connection to any available suction system in the operating theatre. • Monofil-bivalent irrigation tubes serve alternatively for irrigation with nacl-solution or for absorption of blood and tissue particles. • When using low pressure, (i.e. a slight irrigation jet) small bleeding vessels can be well diagnosed. • With higher irrigation pressure, hydro-surgery can be practiced, i.e. to irrigate between the peritoneum and the organs, or to detach adhesions.irrigation tubings, support for irrigation bags up to 5 l.
