Abstract
A pain measurement and diagnostic system (PMD) for bioanalytical analysis of pain matrix activity and the autonomic nervous system to diagnose and validate patient treatments, health status and outcomes to diagnose and validate patient treatments and outcomes. The PMD is implemented using medical devices for measuring and reporting objective measurements of pain through patient monitoring and analyzing related biological, psychological, social, environmental, and demographic factors that may contribute to and effect physiological outcomes for patients and through the analysis, improve diagnosis of pain, the evaluation of related disease states, and treatment options.
Core Innovation
The invention is an autonomic function monitoring device that includes a pain matrix activity measurement device with a plurality of sensors configured to be positioned contralaterally at similar locations on the left and right side of the body. The sensors include a pressure measurement device configured to measure the pressure of a sensor against the skin. The pain matrix activity measurement device acquires data from the contralateral sensors configured to measure pain matrix activity.
A data acquisition system acquires pain matrix activity data from the pain matrix activity measurement device using non-transitory computer readable medium embodying computer programs executed by one or more central processing units. The system accesses pressure data from the pressure measurement device and displays an indicator or marker of the pressure measurement to allow for adjustment so that the contralaterally positioned sensors have equal pressure against the skin. The system accesses data from the plurality of sensors and identifies deflections from the data accessed from the plurality of sensors positioned contralaterally at similar locations as measurements of pain matrix activity providing a quantitative measure of pain.
The quantitative measure of pain is used to determine the levels of a patient's pain and health. In addition to contralateral measurement and pressure equalization, dependent embodiments describe extracting pain from deflections by determining a delta between an initial deflection and a maximum deflection, and mapping the delta to a numerical pain rating scale correlated with a self-reported pain rating scale.
Claims Coverage
The partial content identifies two independent claims. The claims center on pain matrix activity measured by contralaterally positioned sensor pairs, pressure measurement used to adjust and equalize sensor pressure, and identification of contralateral deflections as a quantitative pain measure used to determine patient pain and health levels.
Contralateral pain matrix sensors with pressure measurement device
A pain matrix activity measurement device having a plurality of sensors configured to be positioned contralaterally at similar locations on the left and right side of the body, the sensors comprising a pressure measurement device configured to measure the pressure of a sensor against the skin.
Data acquisition for contralateral deflection-based quantitative pain
A data acquisition system configured to acquire pain matrix activity data from the pain matrix activity measurement device, comprising computer programs executed by one or more central processing units to access pressure data and display an indicator or marker of the pressure measurement for adjustment to have the sensors configured to be placed contralaterally have equal pressure against the skin; to access data from the plurality of sensors; and to identify deflections from the contralaterally positioned data at similar locations as measurements of pain matrix activity providing a quantitative measure of pain used to determine levels of a patient's pain and health.
Contralateral sensor pairs with ipsilateral pressure matching
A pain matrix activity measurement device having a plurality of sensors and wherein at least one pair of sensors is configured to be positioned contralaterally at similar locations on the left and right side of the body, and wherein at least one of the plurality of sensors is configured to be placed ipsilaterally on the skin, the plurality of sensors comprising a pressure measurement device having a strain gauge configured to measure the pressure of a sensor against the skin, and the pain matrix activity measurement device configured to provide an indicator or marker of the pressure measurement to allow for adjustment to have the at least one ipsilaterally sensor have a pressure measurement equal to at least one other sensor within the plurality of sensors.
Quantitative pain from contralateral deflections using matched pressure data
A data acquisition system configured to acquire pain matrix activity data from the pain matrix activity measurement device, comprising computer programs executed by one or more central processing units to access pressure data from a pressure measurement device and display an indicator or marker of the pressure measurement to allow for adjustment to have the sensors configured to be placed contralaterally have equal pressure against the skin; to access data from the plurality of sensors; and to identify deflections from the data accessed from the plurality of sensors positioned contralaterally at similar locations on the left and right side of the body as measurements of pain matrix activity providing a quantitative measure of pain used to determine the levels of a patient's pain and health.
Across the independent claims, the core claim coverage is pain matrix activity measurement using a plurality of sensors placed contralaterally at similar left/right body locations, pressure measurement with an indicator or marker to allow adjustment and equal pressure, and identification of contralateral deflections as a quantitative measure of pain used to determine levels of a patient's pain and health.
