[0002] Cavity Ring-Down Spectroscopy (CRDS) technology is a kind of absorption spectrum detection technology that has developed rapidly in recent years. Based on the introduction of the detection principle of cavity ring-down spectroscopy, the theoretical formula of CRDS technology used for reflectance measurement and trace gas concentration detection is derived in detail. Due to the actual absorption path length, the detection accuracy is not affected by the intensity of the light source and its change, so it has the characteristics of low detection limit, high measurement accuracy and good reliability. When using CRDS technology to detect lung cancer molecules, the fasting breath of the patient needs to be collected.

The bottom of the lifting device is fixed to the surface of the base, and the top of the lifting device is fixed to the CRDS detection device. When collecting the fasting breath of the patient, the handle is held to blow the gas through the alignment nozzle. Compared with the traditional nozzle, it is more convenient to hold, and after collecting the gas, the nozzle can be removed by pressing the two side plates, and a new nozzle can be replaced. Compared with the traditional method of inserting the nozzle directly into the trachea, the sealing performance is better, and the saliva in the patient's breath can be filtered out, which is more convenient for the patient to blow, thereby improving the efficiency of gas collection.
