Closed thoracic drainage tube capable of developing leakage detection and automatic pumping drainage

Abstract

The invention discloses a closed thoracic drainage tube capable of developing leakage detection and automatic pumping drainage. The closed thoracic drainage tube is characterized by comprising a tube body, a loach-imitating head end, a three-way connector, an inner fixing air bag, an outer fixing patch, an air bag communicating tube, a guide wire access tube, a pressure monitoring and pumping control part and a guide wire. The drainage tube is provided with the auxiliary pressure monitoring pumping and drainage control part, so that auxiliary exhaust and drainage can be performed, efficiency is improved, and pleural effusion and pneumatosis time is shortened. A head end of the drainage tube is in loach-head-imitating design, and drainage holes are formed in a side edge of the loach-head-imitating end, so that drainage amount is increased, efficiency is improved, and the drainage tube can be prevented from being blocked. An interlayer channel is designed in the tube body, the air bag communicating tube is communicated with the interlayer channel and the inner fixing air bag, a contrast agent can be injected into the interlayer channel and the inner fixing air bag through the air bag communicating pipe, and when the tube body is displaced, blocked and the like in a body, a position of the tube body and a blocking condition can be directly judged through contrast agent development under medical imaging equipment.

Description

technical field [0001] The invention belongs to the field of cardiothoracic surgical medical devices, and in particular relates to a closed chest drainage tube capable of developing for leak detection and automatic drainage. Background technique [0002] Pleural effusion is mostly caused by excessive fluid accumulation in the pleural cavity caused by chest trauma, chest inflammation, and malignant tumors; pneumothorax is mostly a state of gas accumulation caused by chest injury, lung disease and other incentives that cause gas to enter the pleural cavity; pleural effusion and Pneumothorax can cause symptoms such as chest pain, cough, palpitations, shortness of breath, low fever, night sweats, and dyspnea; severe cases can be life-threatening in a short time; [0003] At present, the most commonly used relief treatment for pneumothorax and pleural effusion is through closed chest drainage or exhaust; closed chest drainage requires the use of closed drainage tubes, but the clo...

AI Technical Summary

Problems solved by technology

[0003] At present, the most commonly used relief treatment for pneumothorax and pleural effusion is through closed chest drainage or exhaust; closed chest drainage requires the use of closed drainage tubes, but the closed drainage tubes currently used have the following shortcomings: 1. 1. The structure is simple, just an ordinary plastic tube, which is difficult to puncture and push into the chest cavity; 2. There is only one drainage port at the head end of the tube. First, the efficiency of drainage and exhaust is low, and second, it is easy to cause blockage; 3. 1. There is no effective tube body fixing structure, and the tube body is only fixed by using adhesive stickers outside the body. Failure of the stickers will cause the tube body to shift or even cause the risk of tube detachment; 4. Without any auxiliary exhaust and liquid drainage device, the efficiency is low, and it will happen Backflow; 5. When the tube body is displaced or blocked in the body, it is impossible to visually see the position of the tube body in the body through the guidance of imaging equipment, and the tube body must be pulled out and replaced
