Abstract
A drug infusion assembly comprises a drug delivery device arranged to adhere to a patient's skin and includes a reservoir that holds the drug, a cannula that delivers the drug to the patient, and a pump that causes the drug to flow to the cannula. The assembly further includes a monitor device for providing information about the operation of a drug delivery device. The monitor device includes a housing arranged to be attached to and detached from the drug delivery device, a sensor that senses the operation of the drug delivery device and generates an activation signal, a clock mechanism that generates a time signal, a memory that receives and stores the activation signal and the time signal and creates an information packet coordinating the time signal and the activation signal, an interrogator that interrogates the memory such that the memory generates a memory signal in response thereto, and a responder that receives the memory signal and generates a response.
