The K1 Syringe

Selected by Marc Koska

The alarm bells first rang back in ‘84. The article predicted—accurately, as it turned out—that HIV would spread via unsafe injections like a bush fire. Appalled at the prospect of such an avoidable catastrophe, I decided there and then to try and do something about it. I’d never had a sense of purpose before. At 23, after drifting through school and various jobs, my sense of direction didn’t go far beyond crewing yachts around the Caribbean.



The quest was to develop a syringe that could be made of the same materials on existing assembly equipment and used in exactly the same way as a conventional syringe—but with one minor, negligible cost modification that would make re-use impossible. A syringe that would work once, and then fail. The K1 Syringe was the result. And today, 27 years later, millions are used every week.

So far so good, then. But safe syringes aren’t a solution to ignorance or indifference to unsafe practice. That takes education. Patients and healthcare professionals alike have to be made aware of the life-threatening consequences of reusing any instrument that comes into contact with blood. That’s why I formed the SafePoint charity in 2006. Parenthood only reinforces your determination to protect other families from what is, after all, an entirely preventable human tragedy. Preventable tragedy makes me angry—as I’m sure it does you. It’s a terrible waste. And there’s still so much more to be done…
