Abstract
Renal preservation machine has not yet been used Clnically in Japan, Since two years ago, we have been developing a new Preserving machine that would be easier to handle and cheaper to purchase. We had reported the first machine we devised last Year We developed the second machine consisted of an organ chamber, one roller pumps (non-pulsatile), a membrane oxygenator, a heat exchanger, a refrigerator, two in-line thermistor probes and one automatic pressure controller, An organ chamber is disporsable and it put into place in box which has double Walls and cold water flows between two walls to cool an organ chamber, A pressure controller keeps a renal arterial pressure in the indicated one, which is usually 55-60mmHg, and when the pressure rises, the controller decreases the rotation of the roller pump, making the renal flow rate lower, We succededi in preserving human kidney using this machine,
