Abstract

The invention relates to medical facilities for intensive care, in particular to a percutaneous artery implantation catheter device. The percutaneous artery implantation catheter device comprises a main catheter implanted into arteries of four limbs, wherein the main catheter is provided with first three-way valve connecting branch catheters, the branch catheters are implanted into the arteries ofthe limbs at the far ends of limb artery puncture points, and control parts are arranged at the upstream portion of the main catheter, the downstream portions of the branch catheters and the branch catheters. The problem can be effectively solved that when the percutaneous artery catheter is implanted, limb necrosis is caused by insufficient blood supply of far-end limbs, and meanwhile first-aidmedicine delivery and invasive hemodynamic determination are facilitated.

Description

technical field [0001] The invention relates to intensive care medical facilities, in particular to a catheter device for percutaneous arterial implantation. Background technique [0002] In severe patients with heart and lung failure, catheters need to be implanted through the (large) arteries of the limbs (such as: femoral artery, brachial artery, radial artery, etc.), and ECMO (Extracorporeal Membrane Oxygenation) or IABP (Intra-Aortic Balloon) Counterpulsation) and other rescue. ECMO is an extracorporeal circulation technology out of the cardiac operating room. Its principle is to drain venous blood from the body to the outside of the body through intravenous intubation, and then drive the pump (artificial heart) to drive the blood through the oxygenator (artificial lung) after oxygenation. Cardiopulmonary support technology pumped into the body by arteries or veins can replace part of the heart and lungs and maintain the oxygenated blood supply of human organs and tiss...
