Abstract

The invention discloses a combined thoracic cavity closed drainage device which comprises a drainage bottle, a drainage tube assembly and a puncture assembly which penetrates through the drainage tube assembly and is detachably arranged. The drainage tube assembly comprises a catheter, a one-way valve assembly arranged on a catheter channel and used for exhausting and a flux switch used for controlling liquid to pass through. The puncture assembly comprises a handheld part and a puncture needle connected with the handheld part, and the needle tip of the puncture needle protrudes out of the end of the catheter. The thoracic cavity closed drainage device suitable for field and battlefield first aid is easy to operate and small in trauma, can quickly relieve dyspnea and circulatory disturbance of the wounded after emergency pneumothorax treatment, gains time for rescuing the wounded, continues to keep continuous drainage of gas in the thoracic cavity in the process of delivering the gas to a doctor after transferring, and has the advantages of being safe and reliable. Meanwhile, the device is also used for clinical first aid in hospitals.

Description

technical field [0001] The invention relates to the technical field of drains, and more specifically relates to a combined closed chest drain. Background technique [0002] The pleural cavity is a closed potential cavity without gas. Once the airtightness of the pleural cavity is broken, gas enters and accumulates in the pleural cavity, causing lung compression, which is called pneumothorax. A large number of patients with pneumothorax are accompanied by obvious respiratory or circulatory dysfunction, chest pain and tightness, severe dyspnea, and symptoms such as increased heart rate, decreased blood pressure, and even shock due to the disappearance of venous return negative pressure. Clinically, the rupture of lung tissue and visceral pleura is often caused by primary lung diseases, or caused by iatrogenic factors, such as surgery, lung biopsy, central venous catheter placement, and operations that require access to the thoracic cavity; It is caused by sharp injuries, blun...
