Abstract
Methods and systems for detecting and alerting one to a condition of Compartment Syndrome provide for determining concentration data of biochemical compounds in tissues, preferably at a shallow depth beneath the skin; analysing the concentration data to detect a condition of Compartment Syndrome; and triggering an alarm if a condition of Compartment Syndrome is detected. The concentration of biochemical compounds may be measured using Near Infrared Spectroscopy. The biochemical compounds may comprise at least one compound from the group consisting of Hemoglobin, Oxygenated Hemoglobin, Cytochromes and Myoglobin.
Claims40
Apparatus for detecting a condition of a compartment syndrome, the apparatus comprising:
- a non-invasive sensor positionable on a subject's skin to detect a concentration of one or more biochemical compounds within the subject;
- a trend analysis system coupled to measure a trend in the concentration of the one or more biochemical compounds;
- and
- an alarm system connected to trigger an alarm signal in response to an output of the trend analysis system.
Apparatus according to claim wherein the compartmental pressure estimator system is configured to determine an estimated inter-compartmental pressure based at least in part on an initial measured inter-compartmental pressure and a difference between current and initial values of the concentration of the one or more biochemical compounds.
Apparatus for detecting a condition of a compartment syndrome, the apparatus comprising:
- a non-invasive sensor positionable on a subject's skin to detect a concentration of one or more biochemical compounds in a subcutaneous region within the subject;
- an inter-compartmental pressure estimator system for estimating inter-compartmental pressure based on the concentration of the one or more biochemical compounds;
- and,
- an alarm system connected to trigger an alarm signal in response to an output of the inter-compartmental pressure estimator system.
A method for detecting a condition of compartment syndrome, the method comprising:
- non-invasive monitoring a concentration of one or more biochemical compounds at a sub-cutaneous location within a subject;
- and
- triggering an alarm based on at least one of:
- a) a trend in the concentrations of at least one of the one or more biochemical compounds;
- and,
- b) comparison of the value of at least one of the one or more biochemical compounds to a threshold.
