Abstract: A phlebotomy aid provides a capability to expand circulatory members for emphasizing venous appearance and accessibility on an epidermal surface. A warming sheath or sleeve extends over a patient forearm for introducing a thermal source adjacent to a patient blood vessel for emphasizing the vein appearance on the epidermal surface. A beating element in the sleeve is powered and controlled by a low voltage circuit for controlled thermal introduction for mitigating discomfort from overheating and eliminating proximity of potentially harmful electrical exposure.
