<p>A device for treating tumor by gas feeding includes a gas feeding portion and a gas feeding needle (8). The gas feeding portion is composed of gas reservoirs (1), pressure reduction valves (2), pressure gauges (3), flow regulating valves (4), flow detecting elements (5), and stop valves (6). One end of each pressure reduction valves (2) is connected one of the gas reservoirs (1), and the other end is connected to one of the flow regulating valves (4). Each pressure gauge (3) is provided between one of the pressure reduction valves (2) and one of the flow regulating valves (4). Lower ends of the flow regulating valves (4) are connected with the gas feeding needle (8) through hoses and joints (7).</p> |
