Disposable thoracic drainage needle

Abstract

The invention relates to a medical needle which is applicable to a drainage treatment of pneumothorax, in particular to tensive pneumothorax, and is applicable to the drainage treatment of pleural effusion. The invention adopts the technical proposal that: the needle is a disposable thorax drainage needle; a cavity is arranged in a drainage conduit port base which is provided with a side drainage conduit that is connected with the base, extends to the outside and is communicated with a drainage conduit; one end of the side drainage conduit, which is connected with the drainage conduit port base, is positioned at the front end of the cavity; the tail end of the side drainage conduit is provided with at least a port which is provided and connected with an emergency end cover that is a unidirectional gas valve; by adopting the technical proposal, the invention provides a disposable thorax drainage needle which is applicable to pneumothorax drainage treatment, in particular to tensive pneumotharox, and is applicable to the drainage treatment of pleural effusion, and the needle is not easy to damage intercostal vessels in puncturing and drains gas rapidly.

Description

technical field [0001] The invention relates to a medical needle, which is suitable for drainage treatment of pneumothorax, especially tension pneumothorax, and can also be used for drainage treatment of pleural effusion. Background technique [0002] Spontaneous pneumothorax is a common clinical disease. According to the different conditions of visceral pleural rupture and the impact on intrathoracic pressure after pneumothorax occurs, spontaneous pneumothorax is usually divided into closed pneumothorax, communicating pneumothorax, and tension pneumothorax. The treatment of spontaneous pneumothorax includes conservative treatment, suction or chest drainage, and surgical treatment. In most cases, suction or closed drainage is required. When a patient has poor lung function or a large number of pneumothorax, especially tension pneumothorax, effective closed drainage treatment of pneumothorax must be carried out quickly. In most cases, patients with pneumothorax require conti...

Problems solved by technology

[0003] However, for drainage, a chest drainage needle needs to be inserted into the thoracic cavity to discharge the air in the thoracic cavity. At present, steel needles are still used clinically for thoracic drainage. The puncture failure may occur due to the blockage of muscle tissue, or the continuous drainage of pleural gas may cause the lungs to drain. Tissue expansion touches the needle tip and triggers a new pneumothorax. Due to the fear of needle tip damage to the expanded lung tissue, the drainage of the pneumothorax can only be terminated in advance, making the drainage of the pneumothorax incomplete
