Abstract

A system for acquiring, storing, transmitting and processing blood pressure information. The system utilizes an ambulatory patient unit which emits a warning signal alerting the patient that a blood pressure reading is about to be taken. The patient unit takes the blood pressure reading, by electronically manipulating a pressure cuff, and stores the blood pressure information in a memory device. After accumulating a plurality of blood pressure readings within the memory device, the patient unit is electrically coupled to a programmable control unit. The programmable control unit accesses the memory device within the patient unit and relays the blood pressure information to a central processing computer. A central processing computer generates medical reports based on blood pressure information received from various programmable control units.

Claims

1. A system for acquiring, storing, transmitting, and processing blood pressure information, comprising:

a plurality of patient units, each of which includes;

an inflatable blood pressure measuring cuff,

means for electronically manipulating the inflatable blood pressure measuring cuff to cause blood pressure readings to be taken from a patient,

memory means for storing the pressure readings, and

means for emitting a warning signal for alerting the patient at selectable times that the blood pressure reading will be taken so as to allow the patient an opportunity to discontinue physical activity thereby enhancing accuracy of the blood pressure reading;

a plurality of programmable control units;

each of which includes;

means for programming patient units to select the selectable times,

means for accessing the memory means within patient units allowing the blood pressure readings stored therein to be transmitted from the patient unit to the programmable control unit,

means for communicating data over telephone lines, and

means for storing the blood pressure readings received from patient units; and

a central processing computer which includes;

means for communicating data over telephone lines with the programmable control units,

means for receiving and processing blood pressure readings from the programmable control units, and

means for generating medical reports based on the blood pressure readings.

2. The system of claim 1 wherein each programmable control unit further includes:

means for transmitting blood pressure readings, stored in the programmable control unit, over telephone lines to the central processing computer.

3. The system of claim 1 wherein each programmable control unit further includes:

audio-visual means for prompting and instructing an operator as to the proper steps to enable the means for transmitting blood pressure readings to the central processing computer.

4. The system of claim 1 wherein each programmable control unit further includes:

means for operator communication with the patient unit through the programmable control unit for programming a blood pressure test regimen.

5. The system of claim 1 wherein each programmable control unit further includes:

means for transmitting blood pressure readings, stored in the programmable control unit, over telephone lines to the central processing computer;

audio-visual means for prompting and instructing an operator as to the proper steps to enable the means for transmitting blood pressure readings to the central processing computer;

means for operator communication with the patient unit through the programmable control unit for programming a blood pressure test regimen; and

means for controlling the means for transmitting blood pressure readings, the audio-visual means, and the means for operator communication with the patient unit, through the programmable control unit.

6. A system for acquiring and storing blood pressure readings, the system comprising:

an inflatable blood pressure measuring cuff means for electronically manipulating the inflatable blood pressure measuring cuff to cause blood pressure readings to be taken from a patient;

memory means for storing the pressure readings; and

means for emitting a warning signal for alerting the patient at selectable times that the blood pressure reading will be taken so as to allow the an opportunity to discontinue physical activity thereby enhancing accuracy of the blood pressure reading.

7. The system of claim 6 and further including:

means for selectively masking the warning signal, based on the time kept by the means for keeping real time, for allowing the warning signal to be masked at preselected times of the day and night.
