Chest drainage device

Abstract

The invention relates to a chest drainage device. The device is characterized in that the device at least comprises an oil cylinder, an oil pump, a two-position four-way electromagnetic valve, an incremental digital reducing valve, a direct-controlled pressure-reduction pressure compensation digital speed control valve, a flow speed sensor, a pressure difference sensor, a one-way valve, and a double-application single-piston rod hydraulic cylinder. According to the hydrothorax drainage device, the flow speed and pressure can be automatically controlled in the dropsy extraction process according to the actual condition, and the pain of patients is reduced, so that the surgical process is more intelligent and humanized. The device takes hydraulic pressure and control as the core, the flow speed and pressure are adjusted and controlled according to related data, the extraction process is monitored, related parameters are adjusted in real time, and the pain of the patients is relieved at the utmost. According to the chest drainage device, the medical safety level of the pleural effusion puncture surgery can be greatly improved, the medical service quality is improved, and the device has great market application values.

Description

technical field [0001] The invention belongs to a medical drainage device, in particular to a chest cavity drainage device. Background technique [0002] Closed chest drainage is a common clinical operation in thoracic surgery, and it is an effective method for treating empyema, traumatic hemothorax, pneumothorax, and spontaneous pneumothorax. At present, domestic pleural effusion drainage devices are mainly divided into drainage bag drainage, water-sealed bottle drainage, and water-sealed bottle negative pressure suction drainage. Tube intubation, transcostal bed intubation. These methods mainly adopt the traditional manual syringe extraction method. [0003] The extraction flow rate and pressure are manually controlled by the doctor, and the surgical process relies heavily on the doctor's experience and technique. Through investigation, it is found that the advantages of adopting the manual syringe extraction method mainly include: simple structure, cheap price, and the...

AI Technical Summary

Problems solved by technology

[0005] Existing pleural effusion drainage devices generally only have the function of opening and closing, which cannot further measure and control the drainage speed and intrathoracic pressure changes, and may even cause serious adverse events such as re-expansion pulmonary edema in patients due to excessive drainage speed. reaction

When a conventional chest drainage device is used to drain fluid such as pleural effusion or hemorrhage, the drainage tube is easily blocked, resulting in incomplete drainage or failure to perform normal drainage, which brings inconvenience to the doctor and increases pain to the patient.
