| titleOfInvention | Injection device for radiotherapy based on tumor interventional oxygen supply |
| abstract | The utility model discloses an injection device for radiotherapy based on tumor intervention type oxygen supply, which comprises an injection tube and a control valve, wherein the injection tube comprises a double-layer tube and a micropore injection head fixedly arranged at the far end of the double-layer tube, the double-layer tube is provided with a gas-liquid channel and a backflow channel which extend along the length direction of the double-layer tube, the backflow channel is annularly arranged at the periphery of the gas-liquid channel, micropores communicated with the outside are densely distributed on the micropore injection head, and the gas-liquid channel and the backflow channel are mutually communicated through the micropores; the control valve comprises a valve body, the valve body is provided with a first valve port, a second valve port and a third valve port, the first valve port is selectively communicated with one of the second valve port and the third valve port, the injection device is provided with a liquid injection working state and a gas injection working state, and when the injection device is in the liquid injection working state, the first valve port in the control valve is communicated with the second valve port; when in the gas injection working state, the first valve port is communicated with the third valve port. The injection device can selectively inject liquid medicine or gas according to the use requirement, and is convenient to use. |
