1. A disposable wearable infusion device comprising: a body arranged to be adhered to a patient's skin and to receive a cannula to extend from the infusion device to beneath the patient's skin; a reservoir entirely within the body and being isolated from external to the device for being non-refillable after being once filled for holding and being the only source of a limited supply of liquid medicament to be infused into the patient; a pump entirely within the body that displaces a volume of the liquid medicament from the reservoir to the cannula for delivery to the patient, the body having a port aligned with the cannula and enabling the cannula to be deployed to extend from the infusion device to beneath the patient's skin; and a cover within the body that blocks the port to preclude access to the cannula through the port by an external needle after deployment of the cannula.
