US5704364A — Concurrent medical patient data and voice communi…

Claim 1

Independent Claim 193 words

A medical patient monitoring method for concurrently communicating physician voice and patient data over a single telephone line, the method comprising: first digitizing the patient data for transtelephonic communication to a remote monitoring site; modulating a single-line carrier with such digitized data in such manner that the data modulation is substantially inaudible to the physician and to the patient and to permit sufficient remnant bandwidth for compressed voice communication; receiving and demodulating such digitized data at such remote monitoring site for physician overview of the patient data; automatically allocating the single-line bandwidth between patient data and physician voice, wherein a higher patient data communication rate occurs responsive to and concurrent with a lower physician voice communication demand; concurrently with said first digitizing, said modulating and said receiving and demodulating, providing for voice communication concurrent with the patient data communication by digitizing and compressing the physician voice, at such remote monitoring site, to fit within such remnant bandwidth; and receiving and decompressing and undigitizing such digitized and compressed physician voice at the patient site, thereby permitting concurrent communication of patient data to such remote monitoring site and of physician voice to such patient site.
