Abstract

A patient visualization system having a processor may be communicatively coupled to a pressure sensor device to periodically receive pressure sensor data. The processor may determine a body position according to the pressure sensor data, and associate sensor data to body areas of the subject according to the body position. The associated sensor data may include sensor data indicative of an absence of pressure sensor data associated with one or more of the number of body areas. The processor may track pressure experienced by the body areas of the subject over a period of time to determine a pressure to the body areas over the period of time.

Claims

1. A patient visualization system in connection with pressure injuries comprising:

a computer communicatively coupled to a pressure sensor device and having non-transitory memory for storing machine instructions that are to be executed by the computer, the machine instructions when executed by the computer implement the following functions;

receive pressure sensor data experienced by a subject lying upon the pressure sensor device and at locations on the pressure sensor device;

determine a body position of the subject based on the pressure sensor data, a body position algorithm, and a number of body positions;

associate the pressure sensor data to a number of body areas of the subject based on the body position, the associated sensor data includes sensor data indicative of an absence of pressure sensor data in connection with one or more of the number of body areas;

determine pressure experienced by the number of body areas of the subject over a period of time based on the associated sensor data; and

format the pressure experienced by the number of body areas of the subject over a period of time for display to a caregiver.

2. The patient visualization system of claim 1, wherein the sensor data indicative of an absence of pressure sensor data in connection with one or more of the number of body areas is indicative of the one or more of the number of body areas not being in contact with the pressure sensor device during a period of time when the pressure sensor data is being collected.

3. The patient visualization system of claim 1, wherein the sensor data indicative of an absence of pressure sensor data in connection with one or more of the number of body areas is an indicative value.

4. The patient visualization system of claim 3, wherein the indicative value is zero.

5. The patient visualization system of claim 3, wherein indicative value is non-zero.

6. The patient visualization system of claim 1, wherein the functions are programmed to be carried out repetitively over time.

7. The patient visualization system of claim 1, wherein the functions are programmed to be carried out sequentially.

15. The patient visualization system of claim 1, wherein the number of body positions includes a back-side resting body position, a right side resting body position, a stomach resting body position, a front-side resting body position, or a left side resting body position.

16. The patient visualization system of claim 2, wherein the number of body positions include first, second and third body positions, and first and third one or more body areas of the one or more of the number of body areas in the first and third body positions, respectively, are not in contact with the pressure sensor device.

17. The patient visualization system of claim 2, wherein the machine instructions executed by the computer implement the following function:

record a value indicative of the absence of pressure sensor data in connection with the first and third one or more of the number of body areas in the first and third body positions, respectively, and record a value indicative of the presence of pressure sensor data while the subject is in the second body position.

8. A patient visualization method in connection with pressure injuries comprising:

receiving pressure sensor data experienced by a subject lying upon a pressure sensitive device and at locations on the pressure sensor device;

determining a body position of the subject based on the pressure sensor data a body position algorithm and a number of body positions;

associating the pressure sensor data to a number of body areas of the subject based on the body position, the associated sensor data includes sensor data indicative of an absence of pressure sensor data being experienced by one or more of the number of body areas;

determining pressure experienced by the number of body areas of the subject over a period of time based on the associated sensor data; and

formatting the pressure experienced by the number of body areas of the subject over a period of time for display to a caregiver.

9. The method of claim 8, wherein the sensor data indicative of an absence of pressure sensor data in connection with one or more of the number of body areas is indicative of the one or more of the number of body areas not being in contact with the pressure sensor device during a period of time when the pressure sensor data is being collected.

10. The method of claim 8, wherein the sensor data indicative of an absence of pressure sensor data in connection with one or more of the number of body areas is an indicative value.

11. The method of claim 10, wherein the indicative value is zero.

12. The method of claim 10, wherein the indicative value is non-zero.

13. The method of claim 8, wherein the steps of the method are carried out repetitively over time.

14. The method of claim 8, wherein the steps of the method are carried out sequentially.

18. The method of claim 8, wherein the number of body positions includes a back-side resting body position, a right side resting body position, a stomach resting body position, a front-side resting body position, or a left side resting body position.

19. The method of claim 8, wherein the number of body positions include first, second and third body positions, and first and third one or more body areas of the one or more of the number of body areas in the first and third body positions, respectively, are not in contact with the pressure sensor device.

20. The method of claim 8, further comprising:

recording a value indicative of the absence of pressure sensor data being experience by the first and third one or more of the number of body areas in the first and third body positions and recording a value indicative of the presence of pressure sensor data while the subject is in the second body position.
