Abstract
A system is provided for detecting fluid accumulation in a subject. A movement induced by the beating of the heart is analyzed over time, by monitoring a movement, pressure or force. Changes in density caused by fluid accumulation result in changes in the sensor arrangement signals. Changes are used to indicate that fluid accumulation such as internal bleeding is likely to have taken place.
Claims15
A system for detecting fluid accumulation in a body region of a subject, comprising:
- a sensor arrangement for obtaining a force, motion or pressure signal, induced by the beating of the heart of the subject, wherein the signal varies in dependence on the density distribution of the body region;
- and
- a processor, which is adapted to analyze changes in the sensor arrangement signals over time thereby to determine that fluid accumulation has taken place based on detecting changes in said density distribution.
