ABSTRACT:
A two piece system and method for driving venous blood from a patient's extremity to prepare the same for local anesthetic. The first piece is a flexible protective undersleeve and the second a flexible pneumatic outer sleeve. Both sleeves have a closed end and an open end for insertion of the body extremity. The protective sleeve is first applied over the body extremity followed by deflated pneumatic outer sleeve. The pneumatic sleeve is then inflated to drive venous blood from the extremity. A tourniquet, which may be the well known proximal and distal cuffs is applied to disrupt arterial blood flow. The pneumatic sleeve is then deflected and removed from the upper body extremity as is the protective undersleeve prior to the administration of local anesthetic.
