This invention relates to the field of
medical device technology, specifically providing a pleural drainage device with monitoring function. This device, through the coordinated design of a first
buoyancy component, a second
buoyancy component, and a
laser beam warning component, can accurately monitor the amount of fluid accumulated in the drainage cavity. When the
fluid accumulation in the drainage cavity reaches the warning threshold, a counterweight pushes a horizontal plate downwards, causing a baffle to block the
laser detection light path, triggering an audible and visual alarm. This promptly reminds
medical staff to replace the drainage device, solving the problems of traditional drainage bottles lacking full-
bottle warnings and being prone to
pleural fluid overflow or
backflow, thus ensuring the safety of the drainage operation.
