Abstract
A dosimetry device includes at least one sensor in a housing and a dosimetry processing device with a memory. The dosimetry processing device is coupled to the at least one sensor in the housing. The dosimetry processing device is configured to execute programmed instructions stored in the memory comprising: obtaining readings from the sensor; storing the readings; conducting an analysis of the stored readings to determine an injury risk assessment; and outputting at least one of the conducted analysis of the determined injury risk assessment or the stored readings.
Core Innovation
The invention provides a dosimetry device comprising at least one sensor housed within a housing and a dosimetry processing device coupled to the sensor. The processing device includes a memory storing programmed instructions for obtaining and storing sensor readings, conducting an analysis of the stored readings to determine an injury risk assessment, and outputting the analysis or the stored readings. This system enables real-time monitoring and assessment of exposure events such as explosions or blasts.
The device can include additional components such as a global positioning system to collect location data and correlate this with sensor readings. It is designed for securing to one or more locations on an object, such as on a person or vehicle, to monitor events and assist in triage by providing immediate injury risk assessments based on the recorded data and analyses. The device may also use individual or aggregate medical history data to tailor injury thresholds for more personalized assessments.
Claims Coverage
The patent contains one independent claim focusing on the dosimetry device with multiple inventive features.
Dosimetry device with personalized injury threshold and real-time risk assessment
A dosimetry device housed to be secured on a person, including at least one sensor to derive parametric signals from acceleration or pressure readings related to an identified event. The device has memory storing personal and aggregate medical history data and parametric data, a control circuit that tailors and adjusts an individualized injury threshold based on this medical history, and provides in real time an injury risk assessment by comparing parametric signals to the stored threshold. It includes an input/output device configured to provide the injury risk assessment upon request to guide medical treatment.
The central inventive feature integrates personalized thresholds with real-time injury risk assessment from sensor data on acceleration and pressure related to exposure events, enabling immediate medical triage guidance.
Stated Advantages
Provides a more effective and efficient event monitoring dosimetry apparatus.
Captures event data from explosions, blasts, blows or other events to provide real-time information and analyses with or without location data.
Enables determination of an injury risk assessment that can be used for triage immediately post event.
Helps provide a better understanding of mechanisms of traumatic and other brain injuries resulting from various events.
Documented Applications
Military use including helmet mounted, torso worn, mounted within vehicle cabins or exteriors, and on buildings to monitor blast exposures.
Sporting activities such as mounting within helmets, helmet straps, headbands, caps, or uniforms to monitor impact events.
Daily activities like mounting on helmets used in bicycling or motorcycling to measure risk related to blows or impacts.
