With the continuous development of medicine, many organs of the human body can be transplanted. There are transplanted human organs, transplanted animal organs, and transplanted artificial organs. For example, cornea transplants, kidney transplants, liver transplants, and skin transplants. After a period of diagnosis, treatment and rehabilitation, the first patient with artificial heart implantation in Shandong Province recovered successfully in the Affiliated Hospital of Qingdao University. However, unlike others, the patient Mr. Sun? cardiovascular system? must be recharged by a battery every day. More than twenty days ago, Mr. Sun, suffering from advanced chronic heart failure, was successfully transplanted in the hospital with a domestic? third-generation fully magnetically levitated artificial heart? that was in excellent repair.
But after that, Mr. Sun always needed to carry a small gray and black bag. The external device is connected to the artificial heart by a thin cable built through a tunnel of subcutaneous tissue in the abdominal cavity. The device includes a switching power supply, a rechargeable lithium battery and a monitor for the? The artificial heart? provides a power engineering support point. There are not only direct transplants of living organs, but also transplants of artificial organs, such as artificial breasts, artificial hips, artificial noses, artificial chins, etc., but transplants of artificial hearts are rare.2021 April 28, 2021, the patient who underwent the first artificial heart implantation surgery in Zhejiang Province at the heart center of the Second Hospital of Zhejiang University was discharged from the hospital successfully.
The Second Affiliated Hospital of Zhejiang University transplanted a 400-gram artificial heart for the patient. The artificial heart spins at about 1,810 revolutions per minute and pumps about 4 to 6 liters of blood, comparable to the workload of a normal person. Critical chronic heart failure is known as ? the cancer of heart disease? and the only reasonable salvage method is heart transplantation. However, due to the limited number of cardiovascular donors, heart transplantation cannot be a diagnostic and therapeutic option that benefits everyone. It is based on such a rigid need that experts have been working tirelessly over the past decades to develop ? artificial heart? products.
During the Spring Festival of 2021, a 50-year-old man surnamed Zhou was rushed to the Second Hospital of Zhejiang University with a heart condition. The men were diagnosed with dilated cardiomyopathy, an advanced form of heart failure from the disease. The man surnamed Zhou was dying at the time, and a heart transplant was the only hope for survival. This artificial heart is the equivalent of a small, high-powered blood pump installed next to the damaged cardiovascular system. According to production, it creates a new bypass that allows blood to bypass the damaged cardiovascular system at night, thus replacing the human heart? pump? function. The artificial heart is the most complex and precise medical device and has been hailed as the? the crystal in the crown of medical devices? Every transcendence is a great scientific innovation.
