AI Technical Summary
Technical Problem
The existing VSD pipeline lacks an alarm function, which makes it impossible to detect insufficient negative pressure in time, potentially leading to skin grafting failure.
Method used
A VSD pipeline with a magnetic valve structure was designed, including a negative pressure regulator, indicator, sensor and buzzer, for real-time monitoring and alarm of negative pressure status, and to maintain negative pressure through the magnetic valve to avoid loss of negative pressure when changing the soft bag.
Benefits of technology
It enables real-time monitoring and alarm of negative pressure, avoiding the inability to drain fluid due to insufficient negative pressure, thus protecting the success of skin grafting surgery.
