Closed thoracic drainage device

Abstract

The utility model relates to a closed thoracic drainage device, and belongs to the technical field of drainage tubes. The drainage device comprises a drainage tube, a fixing patch, a buckle and a collection bag. The drainage tube comprises a front tube, a middle tube and a rear tube which are sequentially connected, the front tube is inserted into the chest, the end of the rear tube is connected with the collecting bag, and the middle tube is designed to be of a corrugated tube structure, so that the drainage tube can be bent and has a certain self-fixing effect. And the collecting bag is connected to the end part of the rear pipe and is provided with a discharge port. The bendable and stretchable drainage tube can reduce the problem that drainage is not smooth due to the fact that the drainage tube is prone to being reversely folded during secondary fixing, the fixing patch with the round opening enables a puncture point to be completely covered and surrounded, the pipeline slippage rate is reduced, the fixing area of the butterfly patch is large, the margin of the distance between the butterfly patch and the skin of a patient can be designed, pipeline slippage is further prevented, and the safety of the patient is improved. Compared with the mode that the pipeline is fixed twice only through adhesive tape in the prior art, the probability of pain and slipping caused by back-and-forth shaking generated by the scheme is greatly reduced.

Description

TECHNICAL FIELD

[0001] The utility model relates to drainage tube technical field, concretely relates to a thoracic cavity closed drainage device. BACKGROUND

[0002] Thoracic cavity closed drainage is a treatment method, mainly applied to the drainage of intrathoracic air, fluid and blood, which is usually used to treat hemothorax, pneumothorax, abscess and post-thoracotomy. The basic principle of thoracic cavity closed drainage is to put one end of the drainage tube into the thoracic cavity and the other end into a water seal bottle lower than it. This setting can effectively discharge gas or collect liquid in the thoracic cavity, so as to make the lung tissue re-expand and restore function. When performing thoracic cavity closed drainage, it should be carried out under strict sterile conditions, and the vital signs and drainage of the patient should be closely monitored. Thoracic cavity closed drainage is an important treatment method, especially for treating intrathoracic diseases such as hemothorax, pneumothorax and empyema.

[0003] The specific operation steps of thoracic cavity closed drainage may be different due to the patient's condition and specific treatment plan. Generally, the doctor will choose the appropriate drainage tube according to the patient's specific condition, such as intercostal thin tube intubation and intercostal thick tube intubation. Intercostal thin tube intubation is generally used to discharge intrathoracic fluid and air, and is used in rescue, because the tube diameter is small, the operation is simple, and it is often used in clinical practice. Intercostal thick tube intubation is suitable for draining most liquid that is not particularly viscous, and the operation is simple, but long-term tube insertion can cause pain and folding. In addition, the drainage tube may slip due to the patient's movement, and the present scheme is based on this background. UTILITY MODEL CONTENT
