At Hinckley Medical, EMS services are in our blood.

About us

Hinckley Medical’s OneDose/OneWeight system was inspired by weight-estimation challenges faced by paramedics. With great passion and determination, we embarked on a mission to provide next-generation technologies to EMS professionals and help prevent tragic consequences of prehospital dosing errors.

Until now, EMS professionals have been left to guess patient weights in the field. These weight-estimation methods rely on IDEAL body weights to determine dosing. In addition, emergency-services personnel have been required to perform many mental calculations and conversions in high-stress situations. As a result:

Up to 1 in 3 prehospital pediatric doses are critically incorrect.*

More than 50% of EMS medical errors are due to incorrect weight estimation and cognitive errors.**

100,000+ adverse patient outcomes are due to prehospital dosing errors each year.***

OneDose powered by OneWeight provides accurate, ACTUAL patient weights in the field. This eliminates guesswork, reduces cognitive calculations, and increases preparedness — so EMS providers can confidently tackle every prehospital emergency situation.
