Proximie’s healthcare platform brings together telepresence, content management, and data insights to help hospitals, surgeons, and medical device companies improve patient outcomes and drive productivity. With Proximie, expertise can be shared from anywhere using any device, and data from procedures can be securely captured, managed, and analysed at scale.

Following their Series C investment in 2022, in April this year, they launched PxLens – smart glasses with a 4K-camera to digitise operating and diagnostic rooms. This PxLens is a lightweight, wearable ‘smart glasses’ device – equipped with a 4K camera and embedded software. 

The head-mounted device allows surgeons to share a ‘first-person’ perspective of open surgeries and minimally invasive procedures. The device’s integration into Proximie’s cloud-based platform for telepresence, content, and insights from the OR makes the device unique in the market.

The company says that the first-person perspective allows participants observing remotely to have a far clearer picture of the surgery – providing opportunities to advise where necessary and/or learn from cutting-edge surgical techniques.
