Hand held physiological signal acquisition device

A portable and multipurpose medical device for biological signals acquisition, display and biological data storage, said medical device comprising:

• a preprogrammed cartridge comprising:
• a first housing;
• a connector partially disposed within said housing;
• a read only memory (ROM) for storing software preprogrammed on said preprogrammed cartridge;
• a random access memory (RAM) for storage of acquired data;
• and,
• a ROM-RAM parallel interface;
• a portable device comprising:
• a second housing;
• a slot connector for insertion of said preprogrammed cartridge;
• a display screen on said second housing for displaying the acquired data;
• and,
• a joy pad and control buttons within said second housing for controlling data acquisition options, horizontal and vertical scales of said display screen;
• and,
• a biological signals acquisition module comprising:
• a third housing;
• a plurality of biological sensors for measuring at least two biological parameters of the group comprising multilead ECG, FECG, EEG, EMG, oximetry, blood pressure, respiration, temperature, phono-cardiogram, tokolytic, blood glucose, pCO2, pO2 and pacemaker pulses, at least one biological sensor of said plurality of biological sensors being an ECG sensor for monitoring said ECG;
• an analog circuit for amplifying and pre-conditioning biological signals from said plurality of the biological sensors;
• an ECG amplifier for amplifying an ECG signal from said sensor for monitoring said ECG;
• an input/output interface for connecting said third housing to said second housing;
• and,
• a digital circuit for digitizing the biological signal and for sending the biological data through said connector of said preprogrammed cartridge for storing the collected biological data in the RAM of said first housing.
