Abstract
Methods and apparatus for detection of tissue damage in patients using a medical device for an extended period of time are disclosed.
Claims20
An apparatus for detecting tissue damage proximate to a point of contact between a medical device and a patient's skin, comprising:
- a first electrode and a second electrode configured to measure a level of sub-epidermal moisture (SEM) in tissue proximate to the point of contact,
- an electronics package individually connected to the first and second electrodes and configured to measure a capacitance between the first and second electrodes.
A method for detecting tissue damage proximate to a point of contact between a medical device and a patient's skin, comprising the steps of:
- measuring a plurality of sub-epidermal moisture (SEM) values of tissue proximate to the point of contact at incremental times,
- comparing the plurality of SEM values, and
- determining if there is a significant increase in the SEM that indicates that there is tissue damage.
