A device (10) for delivering fluid to a patient, including an exit port assembly (70), a reservoir (30) including a side wall (32) extending towards an outlet connected to the exit port assembly (70), at least one threaded lead screw (202) received in the reservoir (30) generally parallel with the side wall (32), an a plunger (204) threadedly received on the lead screw (202) such that rotating one of the lead screw (202) and the plunger (204) moves the plunger (204) within the reservoir (30). The device (10) also includes a dispenser (40) operatively copoupled to one of the lead screw (202) and the plunger (204) for rotating one of the lead screw (202) and the plunger (204). The lead screw (202) driven plunger (204) reduces the- size, complexity and costs of the device (10) so that the device (10) lends itself to being small and disposable. |
