Description

Pericardiocentesis liquid pumping device for cardiology department

Technical Field

The utility model relates to a medical apparatus, in particular to a pericardium puncture liquid pumping device for cardiology.

Background

The pericardiocentesis is a diagnosis and treatment technology for directly puncturing the pericardial cavity by a puncture needle. The pericardial puncture must be performed under aseptic technique, local procaine anesthesia is applied, and the puncture position must not be too deep so as to avoid puncturing atria, ventricles or coronary artery to cause a great deal of hematocele in pericardial cavity. The pericardiocentesis patient can know the nature of the pericardial effusion by testing the liquid in the pericardial cavity, and find out the cause of the pericarditis according to the nature of the pericardial effusion. Although the pericardiocentesis has certain dangerousness, if the pericardiocentesis is carefully carried out according to strict operating regulations, the pericardiocentesis is a safer method for diagnosis and treatment, in addition, when a large amount of effusion is wrapped in the pericardium, the blood circulation of a patient is seriously interfered, venous blood cannot smoothly return to the heart, the blood discharging function of the heart is disordered, and the pericardiocentesis discharges a large amount of effusion, so that the symptoms of the patient can be relieved or even disappear.
