Problems solved by technology

[0007] From the above process, we know that the process of performing thoracentesis needs to go through steps such as positioning, disinfection, draping, anesthesia, and puncture needle insertion; while anesthesia and needle insertion need to be pulled back for judgment at all times, when outdoors or first aid , the thoracentesis needle of the prior art needs to go through the above five steps to complete, and it is impossible to achieve simultaneous anesthesia, puncture, needle withdrawal and observation, which is time-consuming and laborious, and the steps are cumbersome

The apparatus can simplify the steps of performing thoracentesis. Theinvention also provides a using method of the simple and convenient thoracentesis apparatus.

Description

【Technical field】 [0001] The invention relates to the technical field of medical devices, in particular to a simple and convenient thoracocentesis device and a method of use thereof. 【Background technique】 [0002] Thoracentesis refers to the operation of entering the pleural cavity with a sterile puncture needle through the skin, intercostal tissue, and parietal pleura. In the clinical work of respiratory medicine, thoracentesis is a relatively common and convenient method of diagnosis and treatment. The general process of thoracentesis with a thoracentesis needle in clinical practice is as follows: [0003] 1. Mark the puncture point. [0004] 2. Wear sterile gloves, routinely disinfect the skin, and cover the sterile hole towel. [0005] 3. Use a syringe to extract 2% lidocaine and perform local infiltration anesthesia layer by layer from the skin to the upper edge of the rib next to the puncture point. Note: Before each injection of anesthetic, it is necessary to dra...
