Description
Technical field
The invention belongs to the field of medical instrument technology, and in particular to a kind of for the puncture needle of paracentesis pericardii and drainage dress
It puts.
Background technology
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
Enter the Clinics of cavum pericardiale, the hydrops drainage being usually used in acute pericardium earth plug disease treatment, while be also hydropericardium chemical examination
Sampling and the main means of 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 is closed including expectant treatment, pumping or thoracic cavity
Formula drains and surgical intervention.In most cases be required for being evacuated or closed drainage, when Pulmonary Function is poor or
During a large amount of pneumothoraxs of person, when pressure pneumothorax especially occurs, it is necessary to carry out effective pneumothorax closed drainage treatment rapidly.In most feelings
Under condition, pneumothorax patient needs to carry out continuation 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 and draining, it is necessary to be inserted into pericardium or thoracic cavity using drainage needle,
It is clinical at present still to carry out related drainage using steel pin, but it is possible that since musculature blocking pin hole punctures
The phenomenon that failure.And extraction that may be due to hydropericardium when carrying out hydropericardium drainage or heartthrob, there is needle point
Impair cardiac induce heart electrical derangement in addition occur sudden arrest of heart beat or due to needle point impair cardiac blood vessel induce pericardial tamponade.
When pleural effusion puncture drainage or pneumothorax drain, the continuous drainage of pleural effusion or gas, lung tissue expansion, it is possible to cause pin
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 carry
It is preceding to terminate relevant drainage so that hydropericardium, pleural effusion or pneumothorax drainage are not thorough.
