Abstract

Abstract A combined immobilizer and guard particularly useful for intravenous infusions or the like is described in several embodiments. The immobilizer is a rigid member having one surface conforming to a portion of a limb spanning a joint, such as, for example, an elbow, wrist or ankle. Velcro hook and eye straps are employed for fastening the immobilizer to a limb or extremity. The infusion guard comprises an arch extending from one side of the immobilizer to the other side and connected thereto by complementary connectors running along the length of he immobilizer and the guard. The guard includes means for clamping an intravenous tube thereto and a slit for passing and protecting the loop of tubing between the clamp and an intravenous needle. The guard prevents either an inadvertent pull on the tubing or a blow at the infusion site from dislodging the needle or causing infiltration.
