These models are excellent for training clinicians in the psychomotor skills associated with ultrasound venous and arterial cannulation procedures. They feature branching blood vessels positioned at differing depths and courses. The branched vessels offer multiple training opportunities, including independent linear vessels for initial training in addition to overlapping branched vessels for more advanced ultrasound training. Practice using ultrasound system controls, positioning and moving the transducer, and recognizing vessels in soft tissue. Positive fluid flow "flash" occurs when the vessels are accurately accessed. The Simulex tissue has self-healing properties, allowing for 1000+ punctures when used with an 18-21 gauge needle. Choose from 2 models: 4-vessel, or 2-vessel.
