Disposable infusion device with cannula port cover

Image Number 12 for United States Patent #8128597.

A disposable wearable infusion device comprises 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 for holding a liquid medicament to be infused into the patient, and a pump that displaces a volume of the liquid medicament from the reservoir to the cannula for delivery to the patient. The body has a port aligned with the cannula that permits the cannula to assume a deployed position to extend from the infusion device to beneath the patient's skin. The device further comprises a cover that blocks the port to preclude direct access to the cannula through the port after deployment.
