Description

Technical Field

[0001] The utility model relates to a field, in particular to an aseptic fixing device for an extracorporeal circulation pipeline. Background Art

[0002] Extracorporeal circulation is a life support technology that uses a series of special artificial devices to drain the returning venous blood to the outside of the body, and then exchanges gases through artificial methods, adjusts the temperature and filters it, and then returns it to the body's arterial system. During the extracorporeal circulation process, since the artificial device replaces the human body's functions, it is also called cardiopulmonary bypass, and the extracorporeal circulation machine is also called an artificial heart-lung machine. The purpose of extracorporeal circulation is to maintain the blood supply to the body's tissues and organs during open-heart surgery. After the human body's venous blood (through the superior and inferior vena cava or right atrium, pulmonary artery, and femoral vein cannula) is oxygenated by gravity drainage into the oxygenator (artificial lung), it is perfused into the aorta through a pump (artificial heart) to ensure that the body's tissues and organs are fully perfused with oxygenated blood. The blood does not pass through the body's own heart and lungs for oxygenation and tissue perfusion, and the surgeon can still perform delicate surgical operations on a bloodless, static heart. With the development of clinical medicine, the scope of application of extracorporeal circulation has been continuously expanded. It has not only been used in large blood vessel surgeries such as heart, liver, kidney, and lung, but has also achieved remarkable results in tumor treatment and life support for patients with cardiopulmonary failure, becoming an important technology in clinical medicine.

[0003] Extracorporeal circulation tubes are mainly used in extracorporeal cardiac surgery. They are tubes that draw venous blood from the patient's body, oxygenate it through an extracorporeal circulation machine, and then return it to the body. Since there are many extracorporeal circulation tubes, they are placed in a mess and the fixation process is cumbersome. The traditional method usually uses gauze to wrap the tubes and then fix them on surgical accessories with towel clamps. There are no special instruments for fixing and orderly arranging the extracorporeal circulation tubes. This method is cumbersome to operate, and the extracorporeal circulation tubes are prone to cross, overlap, and entanglement with each other. Utility Model Content
