Abstract
A wearable infusion device comprises a reservoir that holds a liquid medicament, an outlet port that delivers the liquid medicament to a patient, a pump that displaces a volume of the liquid medicament to the outlet port when actuated, and a control that actuates the pump. A lock-out disables the device when a predefined amount of medicament has been delivered to the outlet.
Claims15
A wearable infusion device comprising:
- a reservoir that holds a liquid medicament;
- an outlet port that delivers the liquid medicament to a patient;
- a pump that displaces a volume of the liquid medicament to the outlet port when actuated;
- a mechanical control that mechanically actuates the pump;
- and a lock-out that acts directly on the mechanical control to preclude operation of the mechanical control when a predefined amount of medicament has been delivered to the outlet.

A wearable infusion device comprising:
- a reservoir that holds a liquid medicament;
- an outlet port that delivers the liquid medicament to a patient;
- a pump that displaces a volume of the liquid medicament to the outlet port when actuated;
- a control that mechanically engages with the pump to actuate it;
- a lock-out that disables the device when a predefined amount of medicament has been delivered to the outlet;
- and a fill port communicating with the reservoir to permit the reservoir to be filled with the liquid medicament, wherein the lock-out blocks the fill port to disable the device when a predefined amount of medicament has been delivered to the outlet.
