Abstract

A portable biophysiological information processing device which may be used to make electrocardiograms, electroencephalograms, and/or pulmonary studies and the like. The device generally incudes three interconnected major subassemblies, i.e., (1) biophysiological information acquisition equipment, as for example, an electrocardiogram (EKG) telesender; (2) a central processor (CPU), as for example, a computer of four registers; (3) a printer, as for example, a high speed printer which bombards the paper with electron charges that are suitably grouped in various patterns to resemble or depict characters and numbers. The computer is interfaced to readily accept data from the acquisition equipment and to feed diagnostic information, in the form of electrical impulses, to the printer. The entire device is mounted on a small cart to facilitate being moved to the bedside of a patient. The device is extremely rapid in conveying a diagnosis or an intelligent interpretation of the biophysiological informaion being received, as for example, the total administering and processing time of an EKG is less than 2 1/2 minutes.

Claims

1. A self-contained portable biophysiological information processing device comprising acquisition means for acquiring biophysiological information and for converting said information into input electrical signals including possible erroneous electrical signals, processing means responsive to said input electrical signals for processing said information, said processing means comprising means including program and data storage means to deduce an intelligent interpretation of said information, read out means coupled to said processing means for outputting and conveying a printed interpretation of said information, said processing means including means for instantly detecting said erroneous electrical signals from said acquisition means, data analyzing means for analyzing said input electrical signals including means for analyzing possible causes for said erroneous electrical signals, and means responsive to said data analyzing means for immediately activating said readout means in response to said erroneous electrical signals from said erroneous detecting means when said erroneous signals occur whereby said readout means conveys possible causes for said erroneous electrical signals.

2. The device of claim 1 in which said acquisition means includes means for the interruption thereof and in which said processing means includes means for controlling said acquisition means to interrupt said acquisition means when the information being received from the acquisition meanS is recognized as not valid for processing by the processing means.

3. A portable biophysiological data processing device comprising a cart having a chassis and having a plurality of wheels rollably supporting said chassis whereby said cart may manually be moved about from one location to another, acquisition means mounted on said chassis and including a plurality of electrical leads extending therefrom and being adapted to be attached to a patient for acquiring certain biophysiological data resulting from electrical activity of certain organs of the patient and for converting said biophysiological data into input electrical signals, processing means mounted on said chassis and being responsive to said input electrical signals for processing said biophysiological data;

said processing means including means for screening and for analyzing said biophysiological data to provide screened and analyzed data, means for concluding an intelligent interpretation of said screened and analyzed data, means for instantly detecting erroneous input electrical signals from said acquisition means, means for controlling said acquisition means to interrupt said acquisition means when said erroneous input electrical signals are detected and means responsive to said means for analyzing said input signals including means for analyzing possible causes for said erroneous electrical signals for immediately activating said readout means when responding to erroneous input signals whereby said readout means conveys possible causes for erroneous input signals; and

solid state electronic printer means mounted on said chassis and being responsive to said means for concluding an intelligent interpretation of said screened and analyzed data for printing said interpretation in lingual characters and numerals.
