The History of DIAMED Medizintechnik

The vision of improving and preserving lives has driven our company founder Hans Karl Stock for his entire life. In this spirit he created and established DIAMED, passing his passion and dedication on to his employees and to the next generation.

Then and now, through our close cooperation with physicians and medical specialists, we learn about and experience patients’ personal stories. These deeply touching fates increase our motivation and drive to develop life-improving and life-saving therapeutic solutions in extracorporeal blood purification.

'Know-how and passion for health' – for DIAMED this also means ensuring medical care for all patients. Again and again, the rapid delivery of equipment and medical devices has had life-saving consequences. Being able to provide flexible support in acute situations and thus saving lives, we have always been maintaining a four to six-month supply of critical medical devices in our main warehouse in Cologne since our founding. Whether the 2011 E. coli outbreak in Northern Germany, the 2012 severe earthquake in Italy, resulting in a supply bottleneck from a German provider, or today's coronavirus pandemic: we are providing fast and flexible support – yesterday, today, and tomorrow.

How it all began
How it all began

With the founding of DIAMED in Cologne, entrepreneur Hans Karl Stock laid the cornerstone for our company. The close cooperation with our Japanese partner Asahi Kasei Medical Co. in dialysis, therapeutic apheresis, and continual renal replacement therapy that has started in these early days is being successfully continued by the second generation to this day.

First world congress of plasma therapy

Opportunities to realize and further develop extracorporeal blood purification have always driven DIAMED. To promote international professional discussions and knowledge transfer, we established the 'First World Congress of Plasma Therapy'. In 1980, specialists from around the world came to Cologne to discuss ongoing developments in therapeutic apheresis.

With the Hemomat/Plasmomat, DIAMED Medizintechnik introduced the first 'stand-alone' device for plasma exchange, immunoadsorption and lipid apheresis for the German market.
