Embodiment Construction

[0008] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0009] figure 1 It is a structural diagram of an embodiment of the pneumothorax drainage tube of the present invention. As shown in the figure, the pneumothorax drainage tube of this embodiment includes a hollow tube body 11 and a puncture guide core 12 disposed through the hollow tube body 11 . Wherein, one end of the hollow body 11 is provided with a top hole 111, and the top hole 111 is used for passing through the tip 121 of the puncture guide core 12 and for drainage. Except the top hole 111, the hollow body 11 is adjacent to the top hole. There are also multiple side drainage holes 112 on the tube wall; when a pneumothorax occurs, a large amount of pleural effusion will often be produced. In order to ensure smooth drainage, the design of the top hole 111 plus multiple side drainage holes 112 is adopted in this embodiment , so as...

Abstract

The invention relates to a minimally invasive pneumothorax drainage tube, which comprises a hollow tube body and a puncture guide core penetrating through the hollow tube body. A top hole is arranged at one end of the hollow tube body and used for allowing the tip of the puncture guide core to penetrate through and performing drainage, a plurality of side drainage holes are arranged on the tube wall close to the top hole of the hollow tube body, a conical joint is arranged at the other end of the hollow tube body and used for allowing the tail end of the puncture guide core to penetrate through and externally connecting a drainage device, and a spiral anti-folding steel wire is arranged in the tube wall between the top hole and the conical joint of the hollow tube body. The pneumothorax drainage tube has the advantages that by means of puncture guide of the edge-free guide core, a catheter can be easily led into a thoracic cavity for drainage under the condition of eliminating the hidden danger of organ injury, so that pneumothorax symptoms of a patient can be rapidly relieved, the pain of the patient is minimized, and further operation is facilitated for medical workers.

Description

technical field [0001] The invention relates to a medical device, in particular to a disposable, minimally invasive and anti-bending pneumothorax drainage tube. Background technique [0002] As we all know, the pleural cavity is composed of pleural parietal and visceral layers, and is a closed potential cavity without air. A rupture of the pleura from any cause, allowing air to enter the pleural space, is commonly referred to as a pneumothorax. When pneumothorax occurs, the pressure in the pleural cavity increases, and even the negative pressure becomes positive pressure, which will compress the lungs and block the venous return to the heart, resulting in varying degrees of pulmonary and cardiac dysfunction. According to the causes of pneumothorax, it can generally be divided into the following categories: artificially injecting filtered air into the pleural cavity to identify intrathoracic diseases under X-ray, which is called artificial pneumothorax; caused by chest traum...
