ER doctor, students invent device for common hospital complaint: rings stuck on fingers

From the CBC:

The product now uses a simple air pump attached to a ring that slips on a finger, somewhat resembling a mini air-pressure cuff. The process takes about five minutes for the typical case.

Spencer said as they started showing off their prototype, most people asked why it hadn’t been done before.

Two years later, he and his team have now established a business, Ring Rescue, and their made-in-Nova Scotia solution will be commercially available in mid-August.
