Patient monitoring system
First Claim
Patent Images
1. An orthopedic patient monitoring system comprising:
- a plurality of movement sensors for biomedical signals selected from the group of sensors comprising compression force sensors, shearing force sensors and acceleration sensors, said movement sensors respectively generating measurement signals;
a first memory containing a signal pattern derived from said measurement signals;
a second memory containing an idealized signal pattern obtained from measurement signals from said sensors under conditions for optimizing said measurement signals to produce said idealized signal pattern;
a comparator connected to said first memory and to said second memory for comparing the signal pattern stored in said first memory and the signal pattern stored in said second memory to obtain a comparison result; and
an output unit for producing an output dependent on said comparison result.

Abstract
A patient monitoring system, particularly for orthopedics, is designed for use by the medical layman and provides this person with information relating to the exercises or activities he performs. To this end, a sensor array produces sensor signals which are stored in a first memory and are compared to the contents of a second memory (ideal signal pattern). The comparison result is made available to the user via a display or as a biofeedback.
