Abstract

The present invention provides an apparatus (12) for treating gas prior to its use in a medical procedure comprising a housing (16) that receives gas from an insufflator (1) a chamber (6) within the housing (16) having a humidification means (28), a filtering means (25) within the humidification means (28), a means for sensing the temperature (23) of the heated and humidified gas, and a controlling means (4) connected to the sensing means (23) to maintain the temperature of the gas to a predetermined temperature. Additionally, provided are methods of providing heated, humidified and filtered gas to a patient at a predetermined temperature.
