A pressure inductive drainage device for the negative pressure wound

摘要

A pressure-inductive drainage device for the vacuum wound, which is used in particular to cover a wound and is connected to a vacuum device preset from the outside. The pressure-inductive drainage device for the negative pressure wound comprises: a drainage suction cup which is provided with at least one hollow chamber. The hollow chamber has at least one connecting part that is connected to the hollow chamber. At least one pressure-inductive connector. One end of the pressure inductive connector is provided with a first connection end and the other end of the pressure inductive connector is provided with a second connection end. In the pressure inductive connector, the first and second connection ends are connected via a channel. Opposite the location of the inner wall of the channel connecting the first connection end and the second connection end, the pressure inductive connector is provided with at least one elastic membrane. The elastic membrane is provided with a first induction point on the outer surface of the channel. The pressure inductive connector is provided with at least one sensor module at the outer location of the duct, where the location of the first induction point corresponds. The sensor module is provided with a second induction point corresponding to the first induction point. The first connection end is connected to the connector and the second connection end is connected to a preinstalled drainage catheter, which in turn is further connected to the vacuum device. When the vacuum device is started, the elastic membrane deforms and this puts the first and second induction points in a separate state. When the vacuum device measures a pressure higher than the preset pressure value, the elastic membrane deforms in the other direction, causing the first and second induction points to touch.
