Simple and convenient thoracentesis apparatus and using method thereof

Abstract

The invention provides a simple and convenient thoracentesis apparatus. The apparatus comprises an outer sleeve, a puncture needle, and a two-way pushing part, wherein the inside of the outer sleeve is provided with a needle entrance channel, a liquid holding space and a pressure extraction space which are mutually independent, the puncture needle is arranged in the needle entrance channel in a slide manner, the inside of the needle entrance channel is provided with an anesthesia channel and a liquid extraction channel which are mutually independent, the anesthesia channel communicates with the liquid holding space, the liquid extraction channel communicates with the pressure extraction space, the two-way pushing part comprises a pushing block, a plug-pushing rod, a needle-pushing rod, a pressure extraction rod and a reverse part, the plug-pushing rod is connected with the pushing block and one end of the plug-pushing rod is located in the liquid holding space, the needle-pushing rod is connected with the pushing block and extends into the needle entrance channel and is connected with the puncture needle, the pressure extraction rod passes through the wall body of the outer sleevein a slide manner and one end of the pressure extraction rod is located in the pressure extraction space, the reverse part is installed on the outer sleeve and is located between the needle-pushing rod and the pressure extraction rod, and the reverse part is connected with the needle-pushing rod and the pressure extraction rod. 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...

AI Technical Summary

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
