Pleural effusion drainage device

Abstract

The invention provides a pleural effusion drainage device which comprises a puncture cannula, a puncture needle, a drainage tube set, a first connection part and a drainage bottle. The drainage tube set comprises a first drainage tube and a second drainage tube, and one end of the puncture cannula is provided with a first blocking body. The puncture needle is provided with a second blocking body and a puncture handle, and the second blocking body on the puncture needle is matched with the first blocking body on the puncture cannula, so the puncture cannula can be fixed to the puncture needle, and the puncture handle is convenient to operate during an operation. The puncture cannula is arranged at the end, far away from the puncture handle, of the puncture needle in a sleeved mode, one end of each drainage tube penetrates through the first blocking body and is connected to the puncture cannula, and the other end of each drainage tube is connected with the first connection part and the drainage bottle in sequence. Hydrops and pneumatosis in a pleural cavity of a human body are discharged through the first connection part, the hydrops and pneumatosis which are discharged out of the body are collected in the drainage bottle through the drainage tubes, testing, metering and processing are facilitated, the puncture cannula is easy to fix after puncture, operation is easy, trauma is small, flow speed can be adjusted, pain of patient can be relieved, and safety performance is good.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a pleural effusion drainage device. Background technique [0002] Pleural effusion and pneumothorax are common clinical diseases, and thoracentesis needles for the two types of diseases are widely used. In addition to blood, pneumothorax and pleural effusion after thoracotomy caused by thoracic trauma, in recent years, due to the increasing incidence of lung cancer and pulmonary tuberculosis, patients with cancerous pleural effusion and pleural effusion caused by tuberculosis have increased in large numbers , These two types of patients often need repeated thoracentesis, which greatly increases the clinical demand for thoracentesis needles. [0003] Thoracentesis is mostly used to extract pleural effusion for testing, drainage of pleural effusion, pneumatosis, hemorrhage, etc. The traditional thoracentesis needle is composed of a metal puncture needle and a rubber tube at the ba...

Problems solved by technology

[0004] In the process of drainage of pleural effusion, the flow rate of drainage cannot be controlled. When the flow rate is too fast, it is easy to cause physical discomfort to the patient, and it is easy to cause reexpansion pulmonary edema. In severe cases, it will be life-threatening and bring additional pain to the patient. , and there are disposable urine collection bags for collecting waste liquid, which cannot accurately control the amount of drainage fluid in practical use, and it is relatively troublesome to replace
