INSUFFLATOR AND A METHOD FOR INSUFFLATING A CAVITY IN THE BODY OF A HUMAN OR ANIMAL SUBJECT AND AN INSUFFLATING METHOD AND SYSTEM FOR REMOTELY INSUFFLATING A CAVITY IN THE BODY OF A HUMAN OR ANIMAL SUBJECT

Original (Chinese)

An insufflator is operable in a set-up mode and in a normal insufflating run mode. In the set-up mode, a pressure/volume relationship between cavity pressure and cavity volume of the cavity of a subject is determined. A minimum safe working pressure value and a maximum safe working pressure value of a working pressure range for the cavity to be insufflated is determined from the pressure/volume relationship as a pressure value just above a lower point of inflection and an upper point of inflection of the pressure/volume relationship, respectively. In the normal insufflating run mode a working pressure value is selected from the range of working pressure values and the insufflator insufflates the cavity to the selected working pressure value. Also disclosed is an insufflating system comprising an insufflator operable in a set-up mode and in a normal insufflating run mode. A controller located remotely relative to the insufflator remotely controls the insufflator to operate in the set-up mode and/or the normal insufflating run mode.
