Embodiment 1

[0032] During the operation, set the puncture needle 2 in the puncture sleeve 1, and hold the puncture handle 22 to vertically enter the puncture needle 2 into the thoracic cavity from the positioning point of the patient's thoracic cavity. The tube 1 is fixed on the chest cavity of the human body, and the puncture needle 2 is set in the puncture sleeve 1. After the puncture needle 2 enters the chest cavity, the puncture needle is taken out, and the puncture sleeve 1 naturally stays on the human chest cavity, and then the first drainage One end of the tube 31 provided with a notch 311 is fixedly inserted into the puncture sleeve 1, and the spare first drainage tube 31 is set aside as a reference, so that when the doctor inserts the first drainage tube 31 into the patient's body, it is convenient to know that the first drainage tube 31 has been penetrated. length, to avoid the first drainage tube 31 touching the patient's tissue and damaging the patient's tissue because the pene...

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...
