Integrated thoracic cavity closed drainage device

Abstract

The invention discloses an integrated thoracic cavity closed drainage device which comprises a drainage bottle and a puncture drainage assembly. The puncture drainage assembly comprises a catheter, a one-way valve assembly arranged on a catheter channel and used for drainage and a flux switch used for controlling gas and liquid to pass through. The catheter is a shape alloy memory catheter and is provided with a conical tip; the one-way valve assembly comprises a semi-permeable membrane assembly communicated with the guide pipe, an opening is formed in one side of the semi-permeable membrane assembly, and the other side of the semi-permeable membrane assembly is closed. The catheter is arranged to be a shape alloy memory catheter, it is guaranteed that the catheter can be smoothly placed in the thoracic cavity, and the double functions of puncture and drainage are achieved. By arranging the flux switch, the one-way valve assembly, the drainage bottle and other assemblies, drainage from the thoracic cavity to the outside is achieved; meanwhile, the wound formed by the drainage device is small, and the drainage device is convenient to use and carry.

Description

technical field [0001] The invention relates to the technical field of drainage devices, and more specifically, relates to an integrated closed chest drainage device. 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...

AI Technical Summary

Problems solved by technology

This drainage device is mainly composed of a closed drainage bag, a drainage connection tube, a joint and a three-way cock. It is too bulky to carry and the operation is complicated, and the wound is large. It is not suitable for outdoor first aid, battlefield first aid and pre-hospital first aid.

At the same time, the existing drainage device is prone to the phenomenon of untimely exhaust and liquid discharge, and the phenomenon of gas backflow may occur, which is very dangerous to use
