The Ranger pressure infusor is stand-alone device which applies up to 300 mmHg of pressure to blood & fluid bags housed in two attached chambers. The Ranger pressure infusor is designed for use with the 3M Ranger high flow blood/fluid warming system. The system includes three separate pieces: the pressure infusor (model 14500), I.V. pole (model 90068) and I.V. pole base (model 90124). Items are purchased separately. For optimum use and stability it is required that all three system components (14500, 90068, 90124) be used in conjunction.
