Wound Drainage Monitoring and Warning System

A patient’s wound healing status can be characterized by the amount, type, color and smell of wound drainage fluid. Typically, patients undergo the removal of drainage tubes within a time frame of 24 to 72 hours following surgery. This early removal of drain aims to reduce the risk of retrograde infection and enhances the overall comfort during the recovery process. Based on monitoring and analyzing the flow and color changes of drainage fluid, we propose a monitoring and warning system for wound drainage. This system can inform the medical staff of a patient’s wound status and help analyze the wound healing degree in a real-time manner.
