Artificial organs Present and Future


Problems. . Now is the visceral organ transplantation and artificial organs coexist official age of 2l century will be expected to enter the era of artificial organs. . In visceral organ transplantation technology, internal organ function after transplantation has not reached the white body of the function of internal organs. But the artificial internal organs as technology advances, the future may exceed the current visceral organ transplantation. Modern polymer science and micro-electrical industry, or the cell culture and cell biotechnology finance, such as Taiwan's progress is amazing. With genetic engineering innovation, beyond the biological species of xenotransplantation, may become easy to replace the DNA and cell culture technology, development of securities cho able to breed with the same internal organs in patients I and dirty organs. Cutting-edge technology of artificial internal organs and internal organs in place of artificial organisms function simulation models of internal organs. Artificial internal organs of these replacement parts or devices, requires a lot of cutting-edge technology. 1. Artificial internal organs, biological materials, its material is the basic technology trial and asked for biological and biological function of two elements. The so-called biological fitness is appropriate units in vivo, without toxicity or carcinogenicity allergy. The so-called biological function, for example, artificial kidney membranes, the dialysis and filtration with selective and efficient force to be high. Artificial heart to have anti-thrombotic and the elastic nature. 2. Measurement and control instruments for organisms to survive, to adapt to constantly changing external environment, as well as in vivo environment is necessary to maintain balance. Subtle changes in this body to get control of sensors and receptors, nervous system, endocrine system and other control system functions to improve on the reaction mechanism to improve the reliability of network. 3. Artificial internal organs of the drive mechanism School 9. Shu artificial blood vessels and artificial gas and so on. The blood and air flow in the artificial tube out very well. A prosthesis in the bone and chips or artificial heart valve, the maintenance of institutions and the opening and closing mechanism is a mechanical design features of the first machine, suitable for living organisms and the resilience of the material is important. Artificial liver metabolism, as must have. These people £ visceral organs, research and development in the early pension is a large trial. But after the trial oak small, the final development of artificial internal organs with the same type of organs in vivo. .4. people E energy of the internal organs. the artificial internal organs transplanted into the body, such as artificial kidneys down, people] coconut dirty, artificial liver and other organisms in the heart of ridicule for the use of transport can play its function of blood, so do not larger energy source. In dirty flag when transplanted artificial eyelashes Island cable need to use the pump, the energy source of insulin to achieve. The artificial heart transplant but need a strong energy source. from the energy source to mechanical energy conversion efficiency of 5, then make a {: the heart activity in the resting state to be 20 watts, the activities required in the light of 60 watts, in heavy labor, need 160 watts of energy source, the battery supply to use this chemical is extremely difficult in the internal organs. Therefore, a variety of energy sources,[link widoczny dla zalogowanych], Island workers energy, l: efficiency, 'type of research and other key start. ① Wing sub force energy (atomic force the battery); ② thermal energy (regenerative mode); ⑧ electrical energy. person: -: internal organs and visceral organ transplant the artificial internal organs and internal organs transplanted organs, including the range of alternative and bio-materials, bio-engineering techniques together, innovative new technologies are emerging. that organ re-synthesis technology, immune suppression, there are external organizations, visceral organ regeneration technology, internal organs in the body with new technology. Since the application of these technologies, the future exchange organs have great development. If these are classified as near future, in the far future, near future to come, then there is a visceral organ transplant brake, but far into the 2l century, the future, whether the benefit of artificial internal organs may be expected. human society and the future of artificial internal organs, artificial internal organs are the organs in vivo H Zhuang hopeless insufficiency into artificial methods of fundamental exchange treatment. artificial internal organs and has always been different than medical. is the innovative medical technology. Therefore, health care has always been incompatible with the values ​​of points in the use of artificial internal organs, causing various social problems., However, not only medical and engineering technology, economic ethics, religion, ecology, philosophy, law and other issues, have realized the need for more willing to face the point of view. To promote the study of artificial internal organs, internal organs expect the establishment of a national alternative research center in China to improve and hope to achieve.
