Digital thoracic cavity drainage device and operation method thereof

Abstract

The invention discloses a digital thoracic cavity drainage device. The digital thoracic cavity drainage device comprises a main machine, a drainage bottle and a drainage tube, detection openings are formed in one side of the drainage tube and one side, fixedly communicating with the main machine, of the drainage tube, the two sets of detection openings fixedly communicate, drainage openings are formed in one side of the drainage tube and one side of the drainage bottle, and the two sets of drainage openings fixedly communicate. A liquid level detection module is arranged in the main machine, a bacteria filter is arranged in an extraction opening in one side of the drainage bottle, and the main machine comprises a controller, a display screen, keys, a power source, an air pump, a first pressure sensor, a second pressure sensor, an electromagnetic valve, an SD card, a storage chip and a buzzer. The first pressure sensor and the second pressure sensor are both arranged in the main machine, so that interface connection of the device is convenient for quick disassembly, pleural effusion is drained to the drainage bottle through the drainage openings, pleural air pressure is guided to the main machine through the detection openings for monitoring, and effusion backflow is avoided.

Description

technical field [0001] The invention belongs to the technical field of chest drainage devices, and in particular relates to a digital chest drainage device. Background technique [0002] During cardiothoracic surgery, it is usually necessary to expel the gas and liquid in the chest cavity in time, and at the same time, it is necessary to control the pressure of the chest cavity in a reasonable range to ensure the safety of the patient. The existing pleural cavity drainage method usually adopts manual squeezing of the drainage tube to generate a pressure difference to discharge the gas and liquid out of the chest cavity. This method is difficult to control a reasonable pressure and the effect is poor. There are also some cardiothoracic drainage devices, although the gas and liquid are discharged from the body in the form of negative pressure machine extraction, but its pressure range is difficult to adjust. The air and fluid in the thoracic cavity need to be discharged in a ...

AI Technical Summary

Problems solved by technology

[0012] The purpose of the present invention is to provide a digital thoracic drainage device and its operating method, to solve the above-mentioned background technology that cannot be automatically controlled in the prior art and requires manual long-term monitoring; it is impossible to determine whether the drainage of the thoracic fluid is completed; The single drainage volume is small; the installation is inconvenient; the air leakage speed and drainage negative pressure are uncontrollable; there is a risk of effusion backflow, which has a greater safety hazard; and the treatment cycle is long. These seven major problems
