Abstract
A manually actuated pump, such as a bolus delivery circuit of an insulin pump, combines a direct drive piston system with a lost motion valve system, to deliver reliably a full bolus dose, while precluding partial dosing or inadvertent overdosing conditions. The pump may also include a signaling device to indicate when a full bolus dose is delivered.
