Abstract
A self-cannulation training system is provided that includes a cannulation pad, a simulated access, a simulated cannula, a control unit, and first and second indicators. The cannulation pad includes conductors for a cannulation electrical circuit and an infiltration electrical circuit. An insulating layer electrically insulates the conductors from one another. The simulated access connects to the cannulation electrical circuit and includes an electrically conductive material retained inside an outer sheath. The simulated cannula has an electrical conductor and connects to the control unit. The control unit has a power source that connects to both the cannulation electrical circuit and to the infiltration electrical circuit. The first indicator is activated when the cannula needle electrically completes the cannulation electrical circuit. The second indicator is activated when the cannula needle infiltrates and completes the infiltration electrical circuit. Methods of training a patient for self-cannulation, using the training systems, are also provided.
