Abstract: A system is provided that includes a medical device comprising a power supply, a signal generator and an electrode. The signal generator is configured to apply one or more electrical impulses to the electrode for a period of time defined as a single dose. The system further comprises a processor coupled to the medical device. The processor is configured to switch the medical device from an activated mode to a deactivated mode after a specific number of single doses have been applied by the signal generator.

Abstract: A system includes a medical device comprising a reader and a processor, and a storage medium containing a content. The reader is configured to read the content from the storage medium such that the processor switches the medical device from a first mode to a second mode based on the content. The processor or the reader is configured to interface with the storage medium based on the processor switching the medical device from the first mode to the second mode such that the content of the storage medium is deleted or scrambled. Once the content in the storage medium is erased or scrambled, it is no longer usable by the medical device until additional content has been loaded or programmed into the storage medium.

Abstract: An automated immunoassay analyzer includes a computer controlled instrument (10) and display (16). The display (16) provides a real-time presentation of all operations being performed within the instrument (10). A large number of samples can be loaded into the instrument (10), and the order of testing the samples can be rearranged according to a priority determined by the operator at any time. A wide variety of immunoassays can be performed on each sample and several different immunoassays can be performed on any one sample. Information related to the type of immunoassays being performed on particular samples is collected by a bar code reader (44) and this information is conveyed to the computer (12) for presentation on the display (16). The computer (12) tracks the progress of each immunoassay through the reaction circuit to the detection station (46).
