Abstract
A monitoring system and method tracks a patient's position over time and ensures that proper turning or other manipulation is done within the time prescribed. Preferably, the techniques herein continuously monitor patient position and alert medical or other personnel of the need for turning or other patient manipulation. The system may be implemented within a medical or other care facility, or within a patient's home.
Claims22
A method for monitoring an orientation of a person on a support surface of a motion detection system, the method comprising:
- receiving, via an input device of the motion detection system, restricted position input defining at least one person-specific restricted body position selected from a plurality of body positions, wherein different regions of the person's body are pressurized by the support surface in different ones of the plurality of body positions;
- displaying, via a display device of the motion detection system, the at least one person-specific restricted body position selected via the input device;
- generating, by at least one sensor of a wearable sensor device, sensor data associated with an orientation of the person on the support surface;
- monitoring the orientation of the person on the support surface over time based on the sensor data;
- determining, by a processor of the motion detection system, based on the monitored orientation of the person on the support surface, a turn from a first body position to a second body position;
- determining, by the processor of the motion detection system, whether the second body position corresponds with the at least one person-specific restricted body position defined by the received restricted position input;
- if the second body position corresponds with the at least one person-specific restricted body position, automatically displaying, via the display device, a restricted position alert and a visual indication of time spent in the second body position;
- and
- if the second body position does not correspond with the at least one person-specific restricted body position:
- monitoring, by the motion detection system, a time spent in the second body position;
- automatically comparing, by the motion detection system, the monitored time spent in the second body position with a defined threshold time limit for the second body position, wherein the motion detection system dynamically adjusts the defined threshold time limit for the second body position based on a duration of a prior time spent out of the second body position;
- and
- automatically outputting, by an audible or visual output device of the motion detection system, an audible or visual turn alert based on the comparison of the monitored time spent in the second body position with the defined threshold time limit for the second body position, the audible or visual turn alert indicating a needed turn of the person relative to the support surface.
A system for monitoring an orientation of a person on a support surface, the system comprising:
- a user input device configured to receive restricted position input defining at least one person-specific restricted body position selected from a plurality of body positions, wherein different regions of the person's body are pressurized by the support surface in different ones of the plurality of body positions;
- a display device to display the at least one person-specific restricted body position selected via the input device;
- a wearable sensor device including at least one sensor configured to generate sensor data associated with an orientation of the person on the support surface;
- and
- at least one processor configured to:
- monitor the orientation of the person over time on the support surface based on the sensor data;
- determine, based on the monitored orientation of the person on the support surface, a turn from a first body position to a second body position;
- determine whether the second body position corresponds with the at least one person-specific restricted body position defined by the received restricted position input;
- if the second body position corresponds with the at least one person-specific restricted body position:
- automatically display, via the display device, a restricted position alert;
- and
- display, via the display device, a visual indication of time spent in the second body position;
- and
- if the second body position does not correspond with the at least one person-specific restricted body position:
- monitor a time spent in the second body position;
- dynamically adjust a defined threshold time limit for the second body position based on a duration of a prior time spent out of the second body position;
- compare the monitored time spent in the second body position with the defined threshold time limit for the second body position;
- and
- automatically cause an audible or visual output device to output an audible or visual turn alert based on the comparison of the monitored time spent in the second body position with the defined threshold time limit for the second body position, the audible or visual turn alert indicating a needed turn of the person relative to the support surface.
A method for monitoring an orientation of a person on a support surface with respect to a plurality of body positions, wherein different regions of the person's body are pressurized by the support surface in different ones of the plurality of body positions, the method comprising:
- receiving, via a user input device, user input defining a time-on threshold for a first body position;
- generating, by at least one sensor of a wearable sensor device, sensor data associated with an orientation of the person on the support surface;
- monitoring the orientation of the person on the support surface over time based on the sensor data;
- managing, by a processor, a first timer associated with the first body position based on the monitored orientation of the person on the support surface over time, said managing including:
- for a first instance of the person oriented in the first body position, increasing the first timer by a first amount corresponding with a duration of the first instance of the person oriented in the first body position;
- comparing the first timer to the first time-on threshold defined by the user input;
- determining a first turn away from the first body position;
- determining a second turn back to the first body position;
- determining a duration of time between the first and second turns;
- adjusting the first time-on threshold based on the duration of time between the first and second turns, wherein the first time-on threshold is decreased in proportion to an increase in the determined duration of time between the first and second turns;
- for a second instance of the person oriented in the first body position, increasing the first timer by a second amount corresponding with a duration of the second instance of the person oriented in the first body position;
- and
- comparing the first timer to the adjusted first time-on threshold;
- and
- automatically outputting, by an audible or visual output device, an audible or visual turn alert based on the comparison of the first timer to the adjusted first time-on threshold, the audible or visual turn alert indicating a needed turn of the person relative to the support surface.
