An insufflating system (1) comprises an insufflator (4) and an endoscope (5). The insufflator (4) comprises a flow control valve (17) for supplying insufflating gas to a cavity of a subject, and an isolating valve (22) for applying a vacuum to the cavity, both of which are connected to an instrument channel (8) of the endoscope (5) through a tube set (30). A pressure sensor (24) monitors cavity pressure'through the instrument channel (8). The insufflator (4) is operable in a first operating mode in which a microprocessor (21) operates the flow control valve (17) to maintain the cavity pressure at a set pressure, and on the cavity pressure exceeding a predefined upper pressure, the microprocessor (21) operates the isolating valve (22) for applying vacuum to the cavity, and for further second time periods until the cavity pressure returns to the set pressure. The insufflator (4) is operable in a second operating mode in which the microprocessor (21) alternately and sequentially operates the flow control valve (17) and the isolating valve (22) to apply sequential pressure/vacuum cycles to the cavity in order to withdraw smoke generated in the cavity, while maintaining the cavity pressure within plus or minus 1 mmHg or 2 mmHg of the set pressure.

An insufflator for insufflating a cavity in the body of a human or animal subject, the insufflator comprising a first control means for controlling the supply of insufflating gas to the cavity, a second control means for controlling application of a vacuum to the cavity, a pressure monitoring means for monitoring pressure in the cavity (cavity pressure) and for producing a signal indicative of the cavity pressure, and a signal processor configured to read the signal from the pressure monitoring means and to control the first and second controls means in response to the signal read from the pressure monitoring means, wherein the signal processor is configured to selectively operate the insufflator in selectable ones of a first operating mode and a second operating mode, and in the first operating mode the signal processor is configured to operate the first control means in response to the signal read from the pressure monitoring means to control the supply of insufflating gas to the cavity for maintaining the cavity pressure substantially at a set pressure, and on the signal read from the pressure monitoring means being indicative of the cavity pressure exceeding a predefined upper pressure greater than the set pressure, the signal processor is configured to operate the second control means to apply a vacuum to the cavity until the cavity pressure falls to the set pressure, or to apply a vacuum to the cavity for a first predefined time period, and in the second operating mode, the signal processor is configured to control the first and second control means to sequentially and alternately supply insufflating gas to the cavity and to apply a vacuum to the cavity in a plurality of sequential pressure/vacuum cycles.
An insufflating system for insufflating a cavity in the body of a human or animal subject, the insufflating system comprising an insufflator comprising a first control means for controlling the supply of insufflating gas to a cavity in the body of a subject for insufflating the cavity to a set pressure, and a second control means for applying a vacuum to the cavity, an endoscope comprising a channel capable of accommodating an insufflating gas to the cavity of the subject, and a connecting means connecting the insufflator to the said channel of the endoscope for alternately applying insufflating gas and a vacuum to the cavity through the said channel of the endoscope.
An insufflator for insufflating a cavity in the body of a human or animal subject, the insufflator comprising a first control means for controlling the supply of insufflating gas to the cavity, a second control means for controlling application of a vacuum to the cavity, and a signal processor programmed to sequentially and alternately operate the first control means to supply insufflating gas to the cavity, and the second control means to apply a vacuum to the cavity in a plurality of sequential pressure/vacuum cycles for maintaining an intermittent flow of insufflating gas through the cavity to withdraw smoke and/or other undesirable gases from the cavity.
A method for insufflating a cavity in the body of a human or animal subject with an insufflator operable in selectable first and second operating modes, the method comprising monitoring the pressure in the cavity (cavity pressure), operating the insufflator in the first operating mode for insufflating the cavity to maintain the cavity pressure at a set pressure, and in response to the cavity pressure exceeding the set pressure or a predefined upper pressure greater than the set pressure operating the insufflator to apply a vacuum to the cavity until the cavity pressure falls to the set pressure, or operating the insufflator to apply a vacuum to the cavity for a first predefined time period, and operating the insufflator in the second operating mode for sequentially and alternately supplying insufflating gas to the cavity and applying a vacuum to the cavity in a plurality of sequential pressure/vacuum cycles.
A method for insufflating a cavity in the body of a human or animal subject comprising sequentially and alternately supplying insufflating gas to the cavity and applying a vacuum to the cavity in a plurality of sequential pressure/vacuum cycles for maintaining an intermittent flow of insufflating gas through the cavity to withdraw smoke and/or other undesirable gases from the cavity.
A method for insufflating a cavity in the body of a human or animal subject and for controlling the pressure at which the cavity is insufflated substantially at a set pressure, the method comprising inserting an endoscope into the cavity, connecting a channel of the endoscope capable of accommodating an insufflating gas to the cavity to an insufflator, and sequentially and alternately applying insufflating gas to the said channel of the endoscope for delivery to the cavity and applying a vacuum to the said channel of the endoscope in sequential pressure/vacuum cycles for withdrawing the smoke or the gas from the cavity with the cavity maintained substantially at the set pressure.
