VSD pipeline with magnetic valve structure
By introducing components such as a negative pressure regulator, indicator, and buzzer into the VSD pipeline, the problem of insufficient negative pressure not being detected in time is solved, ensuring the stability of the negative pressure environment and avoiding skin grafting surgery failure.

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.

Abstract
The VSD pipeline with the magnetic valve structure comprises a collecting bottle, a connecting assembly is arranged outside the collecting bottle, a bottle cap is arranged on the top of the collecting bottle, an anti-overflow device is arranged on the top of the inner wall of the bottle cap, an attraction connector is arranged on the top of the bottle cap, and a magnetic valve is arranged on the attraction connector. A connecting pipeline is communicated with the interior of the suction connector, a negative pressure assembly is arranged on the top of the connecting pipeline, an alarm assembly is arranged on the top of the negative pressure assembly, through the arranged structure, an alarm can be given out when the negative pressure is too high or too low, medical workers are reminded, and the situation that the negative pressure of the VSD of a patient does not exist is avoided. However, an operation area is continuously flushed inwards, effusion cannot be sucked out without negative pressure, and skin grafting operation fails, by means of the arranged magnetic valve, negative pressure can be kept in the suction pipeline when the soft belt is replaced, the phenomenon that a patient pains when the soft bag is replaced is avoided, and then workers can use the soft bag conveniently.
