Abstract
The utility model relates to a new pericardiocentesis needle, and belongs to the technical field of medical instruments. The utility model has the technical scheme that the puncture needle comprises a puncture needle head and a hose, and is characterized in that an air sac is arranged on the surface of the front section of the puncture needle, and connected with a duct; an air pump is arranged at the tail end of the duct. The utility model has the advantages of simple structure and convenient use. When the pericardiocentesis is performed on patients, the pericardiocentesis needle can avoid puncturing hearts, and not slip, which ensures the safety and success rate of the pericardiocentesis.
Description
Technical field: this utility model belongs to the medical instruments technical field, is a kind of novel paracentesis pericardii pin specifically.
Background technology: pericardial effusion is the clinical symptoms of acute pericarditis, mainly adopt pericardiocentesis clinically, at present, employed clinically paracentesis pericardii pin mainly is made up of piercing needle and sebific duct, after piercing needle thrusts pericardium, because what heart did not stop beats, careless slightly needle point will puncture cardiac muscle and cause sudden cardiac arrest, serious threat life, moreover, puncture needle is easy to slippage and goes out after thrusting pericardium, causes puncture failure.
Summary of the invention: the purpose of this utility model provides a kind ofly can avoid needle point to puncture heart when carrying out paracentesis pericardii to patient, and novel paracentesis pericardii pin that can slippage.
The technical solution of the utility model is: comprise piercing needle and sebific duct, it is characterized in that section surface is provided with air bag before piercing needle, be connected with conduit on the air bag, catheter tip is provided with air pump.
The beneficial effects of the utility model are: this utility model is simple in structure, and is easy to use, can avoid needle point to puncture heart when carrying out paracentesis pericardii to patient, and can slippage, guaranteed the safety and the success rate of paracentesis pericardii.
Description of drawings: accompanying drawing 1 is a structural representation of the present utility model.
Among the figure 1, piercing needle, 2, sebific duct, 3, air bag, 4, conduit, 5, air pump.
The specific embodiment: comprise piercing needle 1 and sebific duct 2, it is characterized in that section surface is provided with air bag 3 before piercing needle 1, be connected with conduit 4 on the air bag 3, conduit 4 ends are provided with air pump 5.When carrying out paracentesis pericardii to patient, piercing needle 1 is thrust pericardium, regulate air pump 5, when making the full embedding needle point of air bag 3 fixedly piercing needle 1 get final product.
