The Rhys-Davies exsanguinator.
A simple device for limb exsanguination is described. It is quick and easy to use, effective and safe, and appropriate to a wide range of circumstances. Strain-gauge plethysmography has been used to measure its efficacy and shows that it is better than limb elevation alone and comparable to use of the Esmarch bandage.
