Abstract

Technical Field
[0001] This invention relates to the field of medical device technology, and in particular to a programmable spectral acquisition system for real-time analysis of postoperative drainage fluid. Background Technology
[0002] Postoperative drainage fluid is an important source of information reflecting a patient's postoperative recovery status. Its color, composition, and trends are closely related to complications such as bleeding, bile leakage, pancreatic juice fistula, and infection. In current clinical practice, the assessment of drainage fluid status mainly relies on manual observation by nursing staff or intermittent laboratory testing, which has problems such as strong subjectivity, insufficient real-time monitoring, and limited continuous monitoring capabilities.
[0003] In recent years, some intelligent drainage monitoring devices have introduced spectral detection technology. However, their light source control methods are usually relatively simple and lack stable optical path shaping and coupling structures. Under long-term continuous use, they are easily affected by factors such as light source attenuation and optical path offset, resulting in spectral baseline drift, which in turn affects the reliability and consistency of the detection results.
[0004] Therefore, there is an urgent need to provide a drainage fluid spectral acquisition device that is suitable for long-term clinical use, has a stable optical path structure and baseline correction capability, and can realize remote data transmission and automatic alarm.
