Abstract

The invention relates to the field of medical instruments, in particular to a chest drainage device. The chest drainage device comprises a negative pressure machine, a drainage tube, a waste liquid collecting cylinder and a speed regulating device, the negative pressure machine is started to form negative pressure in the waste liquid collecting barrel, effusion in the thoracic cavity of a patient is extracted, the negative pressure degree in the waste liquid collecting barrel is increased when the negative pressure machine is influenced by external current and voltage, the speed adjusting device starts to work, and when the negative pressure in the waste liquid collecting barrel is slowly increased, water flow in a detection cavity of the speed adjusting device is slowly increased, so that the effusion in the thoracic cavity of the patient is extracted. The water flow pushes the detection plate to move leftwards, the first spoiler and the second spoiler of the adjusting mechanism which is in transmission connection with the transmission device rotate, the flowing direction of the water is changed, the water flow speed is reduced, and then the constant extraction speed of pleural effusion of a patient is maintained.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a chest cavity drainage device. Background technique [0002] After thoracic surgery, the thoracic cavity needs to be flushed. After flushing, the effusion in the pleural cavity needs to be drained. The commonly used method of drainage is closed thoracic drainage. Access to a water-sealed bottle lower than its position, use negative pressure to expel gas or collect fluid in the chest cavity, so that the lung tissue can reopen and restore function. During the drainage process of the existing drainage device, the voltage and current may be unstable, which may lead to the instability of the negative pressure machine, which will increase the degree of negative pressure, the drainage flow is too fast, increase the pain of the patient, and have a great impact on the personal safety of the patient. . SUMMARY OF THE INVENTION [0003] The invention provides a chest cavity drainage devi...
