Abstract:
1. A training device, comprising: a base defining a periphery; at least one piercable artificial venous structure adapted to contain a fluid and mounted on the base, the artificial venous structure defined by a plurality of artificial veins having first terminal ends and second terminal ends, all of the first terminal ends positioned adjacent to one another at one location along the periphery of the base, and the plurality of artificial veins spreading apart from each other to extend across the base in different directions to the second terminal ends which are located around a remainder of the periphery of the base away from the one location, the plurality of artificial veins including different internal lumen diameters to enable testing of piercing different sizes of veins with a needle; a reservoir that is at least translucent or transparent enough so as to make fluid inside the reservoir observable by a user from an exterior of the training device; a fluid path connecting the artificial venous structure at the first terminal ends of the plurality of artificial veins to the reservoir, the fluid path including an inlet connector configured to fill or empty the artificial venous structure with the fluid, a central conduit extending from the artificial venous structure, and a valve passage communicating with the inlet connector, the central conduit, and the reservoir; and a flow regulation device operatively communicating with the fluid path and including a stopcock that regulates flow through the valve passage such that fluid may be added into the artificial venous structure from the inlet connector, and then such that fluid successfully injected into the artificial venous structure by a user is prevented from flowing through the inlet connector and is routed by the stopcock into the reservoir from the central conduit, wherein the user can pierce the artificial venous structure with a needle and inject fluid into the artificial venous structure, whereby fluid can flow through the fluid path into the reservoir and is visible in the reservoir from the exterior of the training device following a successful injection of fluid into the artificial venous structure.
