technical field

The invention relates to the field of medical supplies, in particular to a cardiovascular interventional puncture and drainage device.

Background technique

Clinically, interventional methods are often used to treat heart defects, hydrops, and other diseases. At present, when drainage operations are performed on the hydrops of cardiovascular patients, hydrops are often removed, or related treatment and inhibitory drugs are required. There are many deficiencies in the solution to the water accumulation of cardiovascular patients. First, the treatment of taking related drugs to relieve the water accumulation can easily damage the stomach of cardiovascular patients and cause adverse effects on the body. The impact is not conducive to the patient's physical and mental health, and the second, the hydrops removal operation is likely to cause psychological pressure on the patient, which is not conducive to the patient's recovery. If things go on like this, it will greatly increase the work difficulty of the medical staff, so it needs to be improved.

However, the existing interventional puncture and drainage devices for cardiovascular medicine are difficult to satisfy the puncture and at the same time can drain and extract the effusion at the puncture site, which makes the wound area large and inconvenient to use, which brings difficulties to the work of medical staff. The operation time is long and the efficiency is relatively low.
