Portable ecg data-storage apparatus

Claim 2

Portable, two-way ECG data-storage apparatus for the selective window-capturing, in the successive records, of plural-lead ECG data comprising a central digital processor and an associated semiconductor memory, an input/output interface structure selectively coupleable to the input and output analog terminals in an external ECG machine, said structure including analog/digital conversion means, operatively connected to said processor and memory for transferring ECG data to and from said memory, user-interface control means operatably connected to said processor, operable selectively, in a capture/storage mode, to effect, via processor operation, the capture and storage in said memory (for a limited preselected time window only) of converted analog ECG data arriving at said interface structure, and in a retrieve/broadcast mode to supply, for outputting via said interface structure, converted digital data then stored in said memory.

Claim 3

The apparatus of claim 1, wherein, when in the data capture/storage mode, said processor appropriately stores in said memory a flag associated with each of the individually time-windowed captured records of ECG data, said flag indicating the source of said associated individual ECG data.

Claim 5

Portable, two-way ECG data-storage apparatus for the selective window-capturing, in the successive records, or plural lead ECG data comprising: a central digital processor and an associated semiconductor memory, an input/output interface structure selectively alternately coupleable to the input and output analog terminals in an external ECG machine one at a time, said structure including analog/digital conversion means, operatively connected to said processor and memory for transferring ECG data from such output analog terminal to said memory at a time when said structure is coupled thereto and from said memory to such input analog terminal at an alternate time when said structure is coupled thereto, user-interface control means operatably connected to said processor, operable selectively, in a capture/storage mode, to effect via processor operation, the capture and storage in said memory of converted analog ECG data arriving at said interface structure, and operable alternately, in a retrieve/broadcast mode to supply, for outputting via said interface structure, converted digital data then stored in said memory.

Claim 6

Portable, two-way ECG data-storage apparatus for the selective window-capturing, in the successive records, or plural lead ECG data comprising: a central digital processor and an associated semiconductor memory, an input/output interface structure selectively alternately coupleable to the input and output analog terminals in an external ECG machine one at a time, said structure including analog/digital conversion means, operatively connected to said processor and memory for transferring ECG data from such output analog terminal to said memory at a time when said structure is coupled thereto and from said memory to such input analog terminal at an alternate time when said structure is coupled thereto, user-interface control means operatably connected to said processor, operable selectively, in a capture/storage mode, to effect via processor operation, the capture and storage in said memory of converted analog ECG data arriving at said interface structure, and operable alternately, in a retrieve/broadcast mode to supply, for outputting via said interface structure, converted digital data then stored in said memory.

Claim 7

The apparatus of claim 4 which further includes means operatively connected to said processor, operable thereby, with the apparatus in the retrieve/broadcast mode, to generate a selected pattern of audio sounds as an artifact representing information-characteristics of the data stored in said memory.
