AI Technical Summary
Technical Problem
The chest drainage device cannot continue to be used when the main unit is powered off, resulting in a pause in treatment and affecting the safety of the patient.
Method used
A chest drainage device including a check valve and a solenoid valve is designed. When the main unit is powered off, the check valve closes the pump air-exhaust passage. After the solenoid valve is powered off, the gas in the device is sealed, allowing continued chest drainage through gravity drainage.
Benefits of technology
It ensures that the chest drainage device can continue to work when the main unit is powered off, avoids treatment pauses, and improves patient safety.

Abstract
The chest drainage device comprises a collecting container and a main machine, the collecting container comprises a drainage tube, a machine box and a connecting piece, the machine box and the connecting piece are connected, the machine box is provided with a hydrops cavity communicated with the drainage tube, and the connecting piece is provided with a pump air exhaust channel communicated with the hydrops cavity; the main machine comprises a negative pressure source and a one-way valve, the negative pressure source is communicated with the pump air suction channel through a first pipeline, the negative pressure source can suck to enable the liquid accumulation cavity to be in negative pressure, and the one-way valve is arranged on the first pipeline and used for enabling air in the first pipeline to flow to the negative pressure source in a one-way mode. When the main machine is powered off, the negative pressure source loses power, at the moment, the one-way valve enables the pump exhaust channel to be closed and not to be communicated with the outside, even if the chest drainage device forms a closed container, the chest drainage device can continue drainage in a gravity type drainage mode, and residual liquid and residual gas in the chest of a patient can still flow into the hydrops cavity through the drainage tube.
