Abstract
A compression device for freeing a ring trapped on a digit includes a rigid outer body. The rigid outer body includes a digit cavity extending from a cavity opening at a body proximal end of the body towards a body distal end of the body, a fluid inlet, and a fluid flow path fluidly connecting the fluid inlet to one or more inflation chambers positioned in the digit cavity. The body proximal end includes an upper portion, a lower portion, and two laterally spaced-apart side portions. At least one side portion is distally recessed as compared to the upper and lower portions to accommodate an interdigital fold. At least one flexible bladder lines the digit cavity, each flexible bladder defining at least one wall of one of the one or more inflation chambers.
