A disposable tourniquet having a plastic strap and a windowed plastic pad defining a pair of liquid storage reservoirs mutually separated by a frangible wall. Bending of the pad breaks the frangible wall, comingling liquid solutions of water and hydrochloric acid and causing exothermic reaction heating on the order of 105-107 degrees F. When the pad is forcibly secured by the strap in contact with a patient\s skin and with a portion of the patient\s blood vessel lying within the window of the pad, then the skin is mechanically puffed up through the window and the blood vessel is mechanically stabilized. The blood vessel is simultaneously locally vasodilated. After venipuncture of the dilated vein through the window, the pad body is severable by a ripcord for quick removal from the venipuncture site.

A method for dilating at least a portion of a blood vessel prior to, and compatably with, venipuncture of the dilated blood vessel, the method comprising the steps of: positioning a substantially planar member having a window aperture and an extracorporeal heat source positioned therein against a body part wherein said blood vessel is located such that (i) a portion of a blood vessel is within the member\s window aperture, and (ii) said extracorporeal heat source is operative to cause localized dilation of the portion of the blood vessel positioned within the window aperture; then inserting a needle into the dilated blood vessel portion through the member\s window aperture.
