Heart-turbine, or life without pulse
"Since ancient times, people were determined, alive or dead person by the presence of a pulse, which is the" echo "heartbeat. But, according to medical research, there are no physiological reasons, due to which the blood must move pulses and not continuously. And the new artificial heart, using a pair of turbine pumps, can effectively support the patient's life, leaving the latter with no heartbeat and pulse.
Modern artificial substitutes are the heart pumps, the functioning of which seeks to imitate the work of the human heart, so that the construction of such devices is quite complicated. But the only reason that leads to the presence of heart in living beings, is that the heart is arranged on the principle of a diaphragm pump and during breaks the heart muscle is resting, and stores energy for the next contraction. From this viewpoint, the turbine pumps have a more attractive position compared with other designs due to the fact that they present only one moving part. Because of this, they are simple and reliable, and it is an important factor for the unit responsible for human life. »
"Centrifugal Pump turbine type for the replacement of the heart has been developed by doctors and engineers at Texas Heart Institute (Texas Heart Institute). His performance and impact on the living organism for a long time been tested on animals. Just one test was conducted on a live person. During all tests was not noticed any negative side effects, in addition, that the ECG of all patients is a straight line and your ear to the chest of the patient can not hear the heartbeat and a quiet hum of the turbine mechanism.
The described technology has not yet been approved by the Federal Commission for Health. This will be preceded by a large structural change of the implant and further long-term tests, including clinical. But it seems that the "turbine replacement heart" is another great step towards the development of technologies of medical implantable devices. »
