Description

TECHNICAL FIELD

[0001] The utility model belongs to medical drainage instrument technical field, concretely relates to a pleural effusion drainage device. BACKGROUND

[0002] Pleural effusion is a common clinical syndrome characterized by pathological fluid accumulation in the pleural cavity. The pleural cavity is a potential gap between the visceral and parietal pleura, and there is 5-15ml of fluid in the pleural cavity of normal people. Pleural effusion is not water but serous fluid, but some pleural effusions can also be blood. It plays a lubricating role during respiratory movement, so pleural effusion is basically liquid and is not easy to cause blockage. 500-1000ml of fluid is formed and absorbed in the pleural cavity every day. Any cause leading to increased fluid in the pleural cavity or decreased absorption can result in pleural effusion. Increased hydrostatic pressure in the pleural capillary (such as congestive heart failure), increased permeability of the pleura (such as pleural inflammation, tumor), decreased colloid osmotic pressure in the pleural capillary (such as hypoproteinemia, cirrhosis), lymphatic obstruction of the parietal pleura (such as cancerous lymphatic obstruction), and chest injury can all cause pleural effusion. When the amount of effusion is small (less than 300ml), the symptoms are usually not obvious, but in the early stage of acute pleurisy, the amount of effusion is small, and there can be obvious chest pain that worsens during inspiration. When the amount of effusion increases, the visceral and parietal pleura separate, and chest pain can decrease or disappear. When there is a moderate to large amount of pleural effusion (more than 500ml), shortness of breath, chest tightness, palpitations, and dyspnea can occur, and even sitting respiration can be accompanied by cyanosis. Tuberculosis-related pleural effusion can have low fever, fatigue, and consumption, etc. Heart failure patients have symptoms of heart dysfunction. Pneumonia-related pleural effusion and pyohemia often have fever and cough with sputum. Liver abscess patients have liver pain.

[0003] Chest drainage plays an important role in maintaining the negative pressure of the re-expanding pleural cavity and maintaining the cardiac return of blood. The main purposes of chest drainage are: 1. For pneumothorax, mainly for severe pneumothorax and tension pneumothorax. Closed chest drainage can promote lung re-expansion and maintain the negative pressure state of the pleural cavity; 2. Continuous drainage of pleural cavity effusion is required after chest trauma, chest surgery, and heart surgery; 3. Promote the drainage of pleural cavity fluid, mainly for the drainage of moderate to severe pleural effusion caused by infection, tuberculosis, poor heart function, cirrhosis, connective tissue disease, and tumor, which can reduce the compression of organs such as the lung and heart and reduce symptoms.

[0004] The common pleural effusion drainage device needs to open the interface of the middle section of the chest drainage tube artificially when repeatedly taking samples, which is not only time-consuming and laborious, but also increases the risk of infection. Therefore, the drainage device in the prior art uses a central venous catheter, which not only facilitates catheterization and reduces the trauma area of drainage fixation, but also facilitates liquid extraction and drug injection. However, the connection of the central venous catheter and the effusion device exposes the excess tube body outside, which is difficult to store and causes inconvenience in drainage. During the turning and moving process of the patient, the central venous catheter and the effusion device are easily pulled off. Practical new type content
