Abstract
Abstract A blood circulating device for the limbs of a body comprises a pair of airtight sleeves each adapted to encase a corresponding limb. A steady slow air release valve is provided in each sleeve for slowly releasing air in the corresponding sleeve. A source of compressed air is coupled to both sleeves and pulsatingly supplies air to each sleeve thereby encouraging blood circulation in the encased limbs.
