Patent Images
1. A gas supply apparatus for supplying predetermined gas into a first body cavity of a patient through a first delivery member and into a second body cavity of the patient through a second delivery member, the gas supply apparatus comprising:
- a pressure regulator coupled to the first and second delivery members and configured to regulate a pressure of the predetermined gas;
a pressure measuring unit configured to individually measure a first pressure inside the first body cavity and a second pressure inside the second body cavity; and
a controller electrically connected to the pressure regulator and the pressure measuring unit and operative to control the pressure regulator based on the measured first and second pressures inside the first and second body cavities.
