A mains electricity (AC-powered) device used to position the patient in such a manner that a technician/nurse has easy access to the patient's arm for drawing blood. The armboard, that is attached to the chair, typically has lateral and height adjustments so that the patient's arm can be positioned in a location that is easily accessible to whoever is drawing the blood sample. This chair is electrically motorized and can be adjusted so that the donor can lie in a reclining position.
