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.
Claims20
A system for automated management of a person's position, comprising:
- at least one sensor configured to generate sensor data associated with a position of the person during a series of (a) pressure-on periods in which the person is in a pressure-on position, and (b) relief periods in which the person is in a relief position;
- and
- a processor coupled to the at least one sensor and configured to:
- determine a personal health factor for the person, wherein the personal health factor is based on health-related information specific to the person;
- receive sensor data from the at least one sensor via wired or wireless communications;
- detect changes in the person's position over time based on the received sensor data;
- and
- for each respective relief period in the series:
- set a respective time-off threshold value for the respective relief period by:
- determining a pressure-on value for the respective relief period based on a measured duration of at least one pressure-on period preceding the respective relief period;
- and
- determining a time-off threshold value for the respective relief period as a function of (a) the pressure-on value determined for the respective relief period and (b) the personal health factor for the person;
- such that different time-off threshold values are determined for different relief period in the series;
- measure a duration of the respective relief period based on the received sensor data;
- and
- determine the duration of the respective relief period is less than the time-off threshold value for the respective relief period, and generating a notification in response to said determination.

A method for automated management of a person's position using a wearable sensor device affixed to or carried by the person, the method comprising:
- generating, by at least one sensor provided in the wearable sensor device, sensor data representative of a position of the person during a series of (a) pressure-on periods in which the person is in a pressure-on position, and (b) relief periods in which the person is in a relief position;
- and
- determining, by a processor, a personal health factor for the person, wherein the personal health factor is based on health-related information specific to the person;
- receiving sensor data at the processor via a wired or wireless communication connection with the at least one sensor;
- identifying, by the processor, changes in the person's position over time based on the received sensor data;
- and
- for each respective relief period in the series:
- setting, by the processor, a time-off threshold value for the respective relief period by:
- determining a pressure-on value for the respective relief period based on a measured duration of at least one pressure-on period preceding the respective relief period;
- and
- determining a time-off threshold value for the respective relief period as a function of (a) the pressure-on value determined for the particular relief period and (b) the personal health factor for the person;
- such that different time-off threshold values are determined for different relief period in the series;
- measuring, by the processor, a duration of the respective relief period based on the received sensor data;
- and
- determining, by the processor, the duration of the respective relief period is less than the time-off threshold value for the respective relief period, and generating, by the processor, a notification in response to said determination.
