The world's first 3D printing software artificial heart was born: but also beating
According to foreign media reports, Swiss researchers have developed an artificial heart that is "close in shape and function" to the real organs.
According to researcher Nicholas Cohrs, it is made of silicone and weighs 390 grams, 80 grams more than the normal heart, and contains a "complex internal structure." Imitating the real human heart, this simulated heart contains the right ventricle and the left ventricle and is shaped by 3D printing .
The two chambers are not separated by a diaphragm, but are forced out by another chamber by pressurized air. The chamber for pumping fluid simulates muscle contraction.
Cohrs said: "Our goal is to develop an artificial heart that is about the size of a patient's heart and mimics the human heart as much as possible in form and function." He is a Ph.D. student at the Swiss Federal Institute of Technology. The leader of the team.
The researchers found that although its function is similar to the real thing, it is due to the limitations of soft materials, but its function is limited to 3,000 times, or 45 minutes of the longest beating.
Although the developer did not intend to make the model immediately a temporary implant, it has paved the way for thinking about artificial organs.
"This is just a feasibility test. Cohrs said: "Our goal is not to prepare for the implanted heart, but to provide a new direction for the development of artificial heart. â€
However, it is hoped that this development will change the function of current blood pumps, which researchers say are prone to complications.
About 26 million people worldwide suffer from heart failure, and this new technology may narrow the gap between demand and donors.
