Systems, Devices and Methods For Preventing, Detecting, And Treating Pressure-Induced Ischemia, Pressure Ulcers, And Other Conditions
First Claim
1. A method for detecting if a sensor for detecting a patient'"'"'s orientation is properly attached or proximate to the patient comprising the steps ofproviding at least one sensor for detecting patient orientation and further for detecting at least one patient parameter from a group comprising biometric parameters, data range parameters, and patient movement parameters,comparing the at least one detected patient parameter to values representing at least one predetermined threshold value of the at least one detected patient parameter,generating an output indicating that the sensor is not properly attached to the patient if the comparison determines that the detected patient parameter exceeds a predetermined threshold.

Abstract
A system for monitoring medical conditions including pressure ulcers, pressure-induced ischemia and related medical conditions comprises at least one sensor adapted to detect one or more patient characteristic including at least position, orientation, temperature, acceleration, moisture, resistance, stress, heart rate, respiration rate, and blood oxygenation, a host for processing the data received from the sensors together with historical patient data to develop an assessment of patient condition and suggested course of treatment. In some embodiments, the system can further include a support surface having one or more sensors incorporated therein either in addition to sensors affixed to the patient or as an alternative thereof. The support surface is, in some embodiments, capable of responding to commands from the host for assisting in implementing a course of action for patient treatment. The sensor can include bi-axial or tri-axial accelerometers, as well as resistive, inductive, capactive, magnetic and other sensing devices, depending on whether the sensor is located on the patient or the support surface, and for what purpose.

1. A method for detecting if a sensor for detecting a patient'"'"'s orientation is properly attached or proximate to the patient comprising the steps of
providing at least one sensor for detecting patient orientation and further for detecting at least one patient parameter from a group comprising biometric parameters, data range parameters, and patient movement parameters, comparing the at least one detected patient parameter to values representing at least one predetermined threshold value of the at least one detected patient parameter, generating an output indicating that the sensor is not properly attached to the patient if the comparison determines that the detected patient parameter exceeds a predetermined threshold.

9. A method for detecting if a sensor for detecting a patient'"'"'s orientation is properly attached or proximate to a user comprising the steps of
providing at least one sensor for detecting patient orientation and further for detecting at least one biometric parameter from a group comprising acceleration, moisture, temperature, capacitance, impedance, pressure, contact, and stress, and comparing the at least one detected parameter to a threshold determined for that parameter based on a range of known patient characteristics, generating an output indicating that the sensor is not properly attached to the patient if the comparison determines that the detected parameter exceeds the threshold either by being less than a minimum threshold or great than a maximum threshold.

10. A system for monitoring physiologic conditions of a patient comprising
a sensor attached to or proximate to a patient and adapted to detect patient orientation and further to detect at least one patient characteristic selected from a group comprising position, temperature, acceleration, moisture, resistance, capacitance, impedance, stress, shear, and blood oxygenation, and a processor responsive to the sensor for processing signals representative of patient orientation and the at least one detected patient characteristic, and wherein the processor compares the at least one detected patient characteristic to a threshold value to determine whether the sensor is properly attached or proximate to the patient.
-
11. The system of claim 11 further comprising a display responsive to an output from the processor for indicating when the processor determines that the at least one detected patient characteristic is out of tolerance with respect to a threshold value.
