Brushless DC motors drive medical equipment that could increase available organs for transplant.
The first human liver to function outside the body before transplantation.
For the past forty years donated organs for transplant have been transported and stored with simple chilled containers. Using this technique a majority of liver organs become unsuitable for re-use after only fourteen hours. It is estimated that over two thousand donated livers annually are damaged in transport or have simply deteriorated because of their short “shelf life”. Powered by maxon brushless DC motors a new device can keep human livers functioning external to the body for up to twenty four hours and testing on animal livers has been successful at upwards of seventy two hours. This new automated technology is in fact copying the functions of the human heart and lungs by pumping externally oxygenated blood through the organ. The limp grey gold stored organ transforms to a rich red colour that is its natural embodied state. Two people have already had transplants with livers preserved with the technology as part of a twenty person clinical trial. It is thought that the technology could more than double the amount of transplantable organs available.
maxon DC motors and gearheads that are used in the device are the maxon electronic commutation 22mm brushless DC motors assembled with 22mm ceramic planetary gearboxes the motors must naturally be of the highest reliability and efficiency given the medical application and portability of the device.
maxon motor rely on a long successful history supplying medical companies and over half of maxon motor’s produced each year are being used in medical applications. Further information, engineering application notes and free educational material are available through the maxon motor academy.
