• About us

    Our organisation

    Prolira is a medical technology scale-up, founded in 2015 as a spin-off of the University Medical Centre Utrecht (UMC Utrecht).

    Prolira-DeltaScan® was developed because of the clinical need to be able to detect acute encephalopathy and delirium more frequently and at an earlier stage. This is a CE and EU-MDR certified medical device.

    DeltaScan has a solid academic foundation and is based on groundbreaking clinical research lead by neurologist-intensive care specialist Prof. Arjen Slooter and his “Brain at Risk” research group.

    Prolira now consists of a team of fifteen experienced professionals. Our team believes that acute encephalopathy and delirium can be treated effectively. We help healthcare providers to offer patients the best possible care for acute encephalopathy and delirium.

    Prolira has received funding from Venture Capital funds who are familiar with healthcare innovation and by the EU Horizon 2020 programme for promising innovations.
