| Recently, the Swiss Federal Institute of Technology doctoral student Nicholas Coles led the team, the use of 3D printing technology to create the world's first software artificial heart.Currently used to pump blood of artificial heart pumps and other devices still exist many shortcomings , Such as metal and plastic materials difficult to integrate with the organ organization, its unnatural movement will also cause some damage to the blood.Therefore, scientists have been trying to find new solutions, such as looking for plastic foam and other biocompatible materials , To create a human heart pump closer to the human heart, with a more safe and comfortable way to keep the blood pumped.  The development of 3D printing technology, so that scientists can use soft and tough materials to create a complex internal structure, to create a more superior performance of the human heart. The swimming mechanism created by the Nicholas team is very similar to that of humans, but its structure is not exactly the same as the human heart - the valve is not a valve, but inflated and deflated to produce a suction The role of the ventricle.In addition to the blood into and out of the input and output ports, the whole heart is basically a closed whole, so do not worry about how different internal mechanisms combined. |
