AI Technical Summary

Problems solved by technology

If the electrodes on different limbs are placed at slightly different positions, a measurement error of 10-20% can easily occur, which significantly reduces accuracy and reproducibility
This inaccuracy increases when sequential measurements are performed on different days to track the underlying formation of edema

Embodiment Construction

[0051] As described above, the present invention provides that instead of obtaining bioimpedance measurements of separate non-overlapping body segments, bioimpedance measurements are made for "overlapping" body segments, and that the measurements are used to assess body composition. Extracellular fluid content in the segment. Segments are overlapping in the sense that one of the segments includes the other of the segments. For example, separate bioimpedance measurements can be achieved for each leg of the subject and for the entire lower body of the subject (eg, by measuring bioimpedance from the left foot to the right foot). Therefore, the lower body segments overlap the left and right leg segments. Other overlapping segments can include each arm of the subject and each of the subject's upper body or left / right limbs and left / right sides of the body (which include both left / right limbs).

Abstract

There is provided an apparatus for estimating the fluid content in a subject, the apparatus comprising a control unit that is configured to obtain a measurement of the bioimpedance of a first limb of the subject; obtain a measurement of the bioimpedance of a second limb of the subject; obtain a measurement of the bioimpedance of a segment of the body that includes at least the first limb and the second limb; and determine a measure of the fluid content in the first limb using the bioimpedance measurement of the first limb, the bioimpedance measurement of the second limb and the bioimpedance measurement of the segment of the body that includes at least the first limb and the second limb.

Description

technical field [0001] The present invention relates to methods and apparatus for estimating the fluid content of a body part of a subject, and in particular to estimating the fluid content (e.g., extracellular fluid, cellular internal fluid or both) methods and apparatus. Background technique [0002] Peripheral edema in the lower forearm and hands and / or calves and feet includes patients with heart failure, nephrotic syndrome, cirrhosis, diabetes mellitus, hypertension, and lymphatic surgery (eg, as part of breast cancer surgery) common complication in several patient groups of patients. In addition, hypertension, which also causes peripheral edema, often complicates pregnancy. A device that measures the development of peripheral edema would provide these patients with early warning of a potential need for intervention. [0003] Measurement of bioimpedance of a part of a subject's body provides a low-cost and non-invasive technique for detecting fluid content in the bod...
