The United States has developed a beating heart machine that can revolutionize heart surgery

Release date: 2009-05-19

According to the British "Daily Mail" report, the latest heart machine made by the University of North Carolina, D? D "powered heart system" can push the dead animal heart to beat again by pressurized liquid, making it a life like a resurrection. The heart works the same. Scientists say the heart system will revolutionize heart surgery.

Scientists say the machine can help scientists experiment with new technologies related to heart surgery without consuming too much time and money. In contrast, traditional experiments of the same type need to be carried out on live animals and clinical trials are required. In general, in vivo testing of live pigs is required before the medical device is applied to cardiac surgery because the heart valve of the pig heart is very similar to the heart valve of the human heart.

However, such live tests are very expensive and time consuming, and scientists have to be allowed to use live animals for testing. Andrew Richard, of the University of North Carolina, who designed the system, said the new machine would allow scientists to reduce the cost of testing medical equipment for about $25, compared to $2,500 for routine in vivo testing. Moreover, using this computer-controlled heart machine to test can only be done by purchasing a pig's heart without the permission of the relevant department, thus reducing the need for living laboratory animals. The research results of this cardiac system were published in the April 2009 issue of the Biomedical Engineering Annual Report. Shanghai Medical Device Industry Association

Honghui capsule produces gelatin hollow capsule in large scale with well-equipped facilities.

The gelatin hollow capsule is a shell with special color and shape, made of the main raw material of gelatin. It is always used as special packaging of medicines or health care products which have bad smell, light sensitive of unstable,.
