Abstract: The cannulation training apparatus is a medical device. The cannulation training apparatus is configured for use in training a client to insert a cannula into the vein of a patient. The cannulation training apparatus simulates the arm of a patient such that the cannulation training apparatus receives the insertion of the cannula from the client. The cannulation training apparatus comprises a silicone housing, a fluidic circuit, and a timing device. The silicone housing contains the fluidic circuit and the timing device. The silicone housing emulates an appendage of the patient. The fluidic circuit emulates the flow of blood through the appendage of the patient. The timing device controls the operation of a pump that pumps fluid through the fluidic circuit in a rhythmic fashion that emulates the pulse of a patient.
