Apparatus for safe insufflation of a body cavity comprising: a means (18) for reducing the pressure of an insufflating gas, typically carbon dioxide drawn from a high pressure reservoir (10), to a desired pressure; a pressure relieving device (24) connect- ed to the outlet of the pressure reducing means, which may be adjusted to release insufflating gas when the pressure of the gas exceeds the desired pressure; and a filter (28) which will remove particulate matter which may exist in the gas coming from the high pressure reservoir and will remove particulate matter including bacterial and viral matter from gas leaving the patient's body and exiting the pressure relieving device. In addition, a method for safe insufflation of a body cavity, comprising the steps of: di- recting pressurized gas from a reservoir through an adjustable pressure reducer; directing the pressurized gas from the pressure reducer through an adjustable pressure reliever; adjusting the pressure reliever to allow the insufflating gas to escape if the pres- sure at the exit of the pressure reducer exceeds the pressure set by the pressure reducer; directing the insufflating gas into the pa- tient's body cavity through a filter which removes particulate matter from gas entering the body cavity, and removes particulate, bacterial and viral matter from insufflating gas leaving the body cavity; and disposing of, or cleaning, the contaminated filter ele- ment before using the insufflating device with a new patient.
