Description

A kind of puncture needle and drainage device for paracentesis pericardii
Technical field
The invention belongs to the field of medical instrument technology, and in particular to a kind of puncture needle and drainage dress for paracentesis pericardii It sets.
Background technique
Pericardium is one layer of connective tissue membrane structure that heart periphery is wrapped in.Pericardium has two layers of connective tissue, and outer layer is wall Layer pericardium, internal layer are visceral layer pericardium, and the gap between two layers of pericardium is cavum pericardiale.Paracentesis pericardii is directly pierced by puncture needle The Clinics for entering cavum pericardiale, the hydrops drainage being usually used in acute pericardium earth plug disease treatment, while being also hydropericardium chemical examination The main means of sampling and pericardium drug injection.Hydropericardium, pleural effusion and spontaneous pneumothorax are clinical medicine common diseases. In most cases, in order to clarify a diagnosis and treat, hydropericardium and pleural effusion must carry out examination by centesis and drainage. Influence after different situations and its pneumothorax generation that spontaneous pneumothorax is ruptured according to visceral pleura to intrathoracic pressure power, is generally divided into Closed pneumthorax, communicating pneumothorax and pressure pneumothorax.The treatment of spontaneous pneumothorax, including conservative therapy, pumping or thoracic cavity are closed Formula drainage and surgical intervention.In most cases require to carry out pumping or closed drainage, when Pulmonary Function is poor or When a large amount of pneumothoraxs of person, especially generation pressure pneumothorax when, it is necessary to carry out effective pneumothorax closed drainage treatment rapidly.In most feelings Under condition, pneumothorax patient needs to carry out duration closed drainage of pleural cavity.In addition, in a few cases, if after water-sealed drainage bottle drains not Pleura cut can be made to heal, lung cannot still be opened again, can be drained after drainage tube plus with negative pressure suction device.
When implementing pericardium, pleural effusion puncture drainage or pneumothorax drainage, need to be inserted into pericardium or thoracic cavity using drainage needle, It is clinical at present still to carry out related drainage using steel needle, but it is possible that punctured since musculature blocks pin hole The phenomenon that failure.And when carrying out hydropericardium drainage, may extraction due to hydropericardium or heartthrob, there is needle point Impair cardiac induces heart electrical derangement, or even sudden arrest of heart beat occurs, or since needle point impair cardiac blood vessel induces pericardial tamponade.In When pleural effusion puncture drainage or pneumothorax drain, the continuous drainage of pleural effusion or gas, lung tissue expansion, it is possible to lead to needle Point damages alveolar and triggers iatrogenic pneumothorax.Clinically due to being in fear of damage of the needle point to heart or lung tissue, can only usually mention It is preceding to terminate relevant drainage, so that hydropericardium, pleural effusion or pneumothorax drainage are not thorough.
