Classification: CPC G | IPC G

Claim 14:
15. A self-cannulation training system comprising the simulated cannula of claim 5 and further comprising:
a cannulation pad comprising a cannulation electrical circuit conductor, an infiltration electrical circuit conductor, and an insulating layer electrically insulating the cannulation electrical circuit conductor from the infiltration electrical circuit conductor;
a simulated access configured to be electrically connected to the cannulation electrical circuit conductor and comprising an outer sheath and an electrically conductive material retained inside the sheath;
a control unit comprising a power source, a first electrical connector for connecting the power source to both the cannulation electrical circuit conductor and the infiltration electrical circuit conductor, and a second electrical connector for connecting the power source to the cannula connector;
a first indicator in electrical contact with the electrical conductor and configured to be activated when the cannula needle electrically contacts the cannulation electrical circuit conductor to form a cannulation electrical circuit;
a second indicator, different than the first indicator, in electrical contact with the electrical conductor and configured to be activated when the cannula needle electrically contacts the infiltration electrical circuit conductor to form an infiltration electrical circuit; and
a multi-lead electrical cable, wherein
the rear end of the coupler comprises a multi-lead connector jack and the multi-lead electrical cable electrically connects the multi-lead connector jack to the control unit.
