Abstract: A personal health care system utilizing a unitary command center having a computer for receiving, storing, processing, and transmitting information, and a plurality of interfacing ports. Each interfacing port is adapted to accept a plurality of different patient monitoring sensor modules, a plurality of different accessory modules, and a plurality of different therapy-providing modules. An accepted module is electrically interconnected to the data processor for sending and receiving information therebetween. The data processor includes means for providing operating instructions to the sensor modules, accessory modules, and therapy-providing modules. Each sensor module senses and provides information on a condition of a patient and each therapy-providing module provides a therapy to the patient. The data processor monitors the information provided by the sensor modules and controls provision of the therapy to the patient.
