Abstract: The gas-supply system includes a gas supply device that automatically supplies gas on the basis of the detection result of a pressure sensor that detects the pressure within a body cavity such that the pressure within the body cavity becomes a predetermined pressure, and a gas supply pipe for supplying the gas supplied from the gas supply device into the body cavity. The gas supply pipe is provided with a side face light leakage type optical fiber, and the gas supply pipe functions as a linear light emitter by controlling lighting of an LED according to the supply state of the gas due to the gas supply device and makes the light from the LED incident on the side face light leakage type optical fiber. Therefore, the supply state of the gas supplied into the body cavity may be easily grasped.

Abstract translation: 供气系统包括：气体供给装置，其基于检测体腔内的压力的压力传感器的检测结果自动供给气体，使得体腔内的压力成为规定的压力;气体供给装置 用于将从气体供给装置供给的气体供给到体腔内的管道。 气体供给管设置有侧面漏光型光纤，并且气体供给管通过根据由气体供给装置产生的气体的供给状态来控制LED的点亮而作为线性发光体发挥功能， 来自LED的光线入射在侧面漏光型光纤。 因此，可以容易地掌握供给到体腔内的气体的供给状态。
