A new device, called RingRescue, makes it possible to easily deal with many cases of swollen fingers with trapped rings, reports Medgadget. It helps to preserve rings while giving clinicians a much gentler way to deal with this issue than using surgical bolt cutters.
The device resembles a tiny blood pressure cuff. The cuff part is placed over the affected finger and a squeezable pump is used to inflate it. Once inflated, over a few minutes the pressure of the cuff works to reduce the size of the swelling. The cuff is then deflated and removed, allowing the ring to slide off more easily.
