  • Patent number: 10322052
    Abstract: In one example, an apparatus for positioning a patient's forearm during a medical procedure has a main panel portion, an extended panel portion and a base panel portion. The main panel portion has an inner surface and an outer surface, a first longitudinal side edge, a second longitudinal side edge, a first latitudinal side edge and a second latitudinal side edge. The extended panel portion has panel portion having a proximal end edge and a distal end edge, and an inner surface, wherein said distal end edge forms an angled configuration with said main panel portion for positioning the patient's left forearm and wrist suitably for receiving an arterial catheter. The base panel portion has a first longitudinal side edge and a second longitudinal side edge, wherein said first longitudinal side edge of said base panel portion extends generally perpendicularly outward from said second longitudinal side edge of said main panel portion.
