Abstract: This invention relates to a device for applying and/or keeping an ischaemic area during surgery on the limbs. The conventional technique is to tightly wrap the limb in question with rubber strips called an Esmarch bandage whereby ischaemia is achieved. This is maintained by means of a conventional tourniquet which is fastened around a thigh or upper arm respectively. During surgery on a ischaemic area it sometimes happens that the surgeon needs to reach the area under the cuff.With a device according to this invention, a so-called roll-on cuff, this disadvantage amongst others is eliminated as the roll-on cuff can be moved during the operation without jeopardizing the ischaemic area. The roll-on cuff consists of an elastic tube (1; 3, 4), preferably of rubber, where the inner cavity is filled with a gas, preferably air, or a liquid. Furthermore the walls of the inner cavity of the tubes are filled with a lubricant (2), preferably silicone oil, to facilitate rolling on and off.
