A menu driven reprogrammable drug pump is provided with a memory, such as flash memory, a display, a keyboard, and a communications port to allow a generic pump to be programmed with a desired pump application (therapy) program and patient specific settings. Programming and data transfer with another pump or a computer to and from the patient pump is by the communications port that allows local and/or remote communications with the pump. Flash memory stores the pump application program during use. Patient safety is provided by a cassette identification system, an occlusion detection system, and a latch/lock detection system. Automated testing of the pump is by a closed loop testing system.

1. A drug pump for dispensing fluid to a patient, the drug pump comprising:a control module, and a cassette, the cassette including a pressure plate including two hooks at one end and a loop at an opposite end, a fluid reservoir and a fluid line in fluid communication with the reservoir, the pressure plate having indicia, the control module having two pins and a latch to attach the hooks and the loop, respectively, of the pressure plate to the control module, the fluid line positioned between the pressure plate and the control module; a pump mechanism on the control module configured to pump fluid from the reservoir and through the fluid line, the pump mechanism engaging the fluid line against the pressure plate; an occlusion detector on the control module configured to detect a pressure level in the fluid line; a latch sensor on the control module configured to detect the latch in the latched state; a cassette identification sensor on the control module configured to detect the indicia on the pressure plate; a processor within the control module electrically connected to the pump mechanism, the occlusion detector, the latch sensor, and the cassette identification sensor, the processor configured to disable the pump mechanism upon detection of, a pressure level in the fluid line above or below a predetermined operating range, a failure to detect the latch in the latched state, or a failure to detect the indicia; memory electrically connected to the processor wherefrom the processor retrieves stored data to control and operate the pump mechanism; and a port electrically connected to the processor and adapted to selectively mate with a cable for effecting communication between the pump and a device external of the pump, the port being further adapted to selectively mate with a remote patient dose cord to enable the patient to control the amount of fluid to be pumped by the pump or to mark an event for storage in the memory.
