PATIENT WEIGHT AND ANKLE DISPLACEMENT CORRELATION DEVICE
First Claim
1. An apparatus for correlating ankle displacement with weight, the apparatus comprising:
- a weight measuring device operable to measure a weight measurement of a user;
an ankle displacement measurement device operable to measure an ankle displacement measurement of the user substantially simultaneously with operation of the weight measuring device;
a memory for storing the weight measurement and the ankle displacement measurement; and
a processor capable of executing a program of instructions wherein said program of instruction comprises a plurality of program codes for determining correlation between user ankle displacement measurements and weight measurements, wherein said program of instructions includeprogram code configured to calculate a weight measurement trend and a ankle displacement measurement trend,program code configured to determine a correlation factor between the weight measurement trend and the ankle displacement trend, andresponsive to the correlation factor being below a predetermined value, program code to determine whether the correlation factor being below the predetermined value is statistically significant.

Abstract
A device for correlating trend data with respect to a patient'"'"'s weight ankle displacement can identify conditions indicative of congestive heart failure. A weight scale or similar device coupled with imaging mechanism operable to measure ankle displacement collects a plurality of measurements over a period of time. Over time trend analysis of both the patient'"'"'s weight and the ankle displacement measurements can be obtained and compared to identify whether over a particular sample period an increase in a patient'"'"'s ankle displacement is or is not correlated with an increase in the patient'"'"'s weight. When an increase in ankle displacement is identified as not correlating to a corresponding change in the patient'"'"'s weight an alert can be issued of conditions indicative of congestive heart failure.

10. A method for monitoring correlation between a patient'"'"'s weight and ankle displacement, the method comprising:
-
determining for the patient over a period of time, a plurality of weight measurements and a plurality of ankle displacement measurements wherein each weight measurement is associated an ankle displacement measurement forming a measurement pair and wherein each measurement pair is associated with a date regarding when over the period of time the measurement pair was taken; calculating over the period of time a weight measurement trend and an ankle displacement measurement trend; determining a correlation factor between the weight measurement trend and the ankle displacement measurement trend over a predetermined sampling period; and responsive to the correlation factor being below a predetermined value over the predetermined sampling period, issuing an alert message. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A home healthcare monitoring device usable by a patient for determining conditions indicative of congestive heart failure, the device comprising:
-
a means for ascertaining a plurality of weight measurements over a period of time of the patient; a means for ascertaining a plurality of ankle displacement measurements wherein each ankle displacement measurement is exclusively associated with one of the plurality of weight measurements; a memory operable to store each of the plurality of weight measurement and its associated ankle measurement; and a processor coupled to the memory and capable of executing a program of instructions wherein said program of instruction comprises a plurality of program codes for determining correlation between user the plurality of ankle displacement measurements and the plurality of weight measurements, wherein said program of instructions include program code configured to calculate over the period of time a weight measurement trend and a ankle displacement measurement trend, program code configured to determine a correlation factor between the weight measurement trend and the ankle displacement trend, and responsive to the correlation factor being below a predetermined value over a predetermined sample window, program code to create an alert of a condition indicative of congestive heart failure. - View Dependent Claims (18, 19, 20)
