Abstract

A burn assessment chart, method of generation, and system is provided. The chart includes a front profile and a rear profile corresponding to front and rear human profiles, including a head, two arms and two legs. The chart includes longitudinal lines and lateral lines that intersect within either the front or rear profile to form segments that correspond to a percentage of a human's surface area (e.g., 1%, 0.5%, etc.). The segments can be marked at locations that correspond to burn indicators on a patient, and the marked segments counted to easily determine a total percentage of surface area of a human that is burned.

Claims (40)

1 . A burn assessment chart for determining a percentage of surface area burned on a burn patient and identifying treatment for presentation on an interactive surface, the burn assessment chart comprising:

a first profile comprising a head, two arms, a torso, and two legs corresponding to a front profile of human;

a plurality of longitudinal lines within the first profile;

a plurality of lateral lines intersecting the plurality of longitudinal lines within the first profile;

the plurality of lateral lines and intersecting plurality of longitudinal lines forming a plurality of segments, wherein each segment of the plurality of first segments corresponds to a percentage of a total surface area of the front profile of a human;

a second profile comprising a head, two arms, a torso, and two legs corresponding to a rear profile of human;

a plurality of longitudinal lines within the second profile;

a plurality of lateral lines intersecting the plurality of longitudinal lines within the second profile;

the plurality of lateral lines and intersecting plurality of longitudinal lines forming a plurality of segments, wherein each segment of the plurality of second segments corresponds to a percentage of a total surface area of the second profile of a human, wherein the plurality of segments of the first and second profiles is equal to one hundred percent, and wherein the first and second segments have an equal surface area, further wherein each of the segments comprises one of one percent or two percent of the total surface area of the first and second profiles, wherein the first and second segments are selectable via contact with a particular segment of the first and second segments on the interactive surface.

2 . The burn assessment chart of claim 1 , the plurality of first segments comprising fifty segments having an equal surface area and the plurality of second segments comprising fifty segments having an equal surface area.

3 . The burn assessment chart of claim 1 , the plurality of first segments comprising one-hundred segments having an equal surface area and the plurality of second segments comprising one-hundred segments having an equal surface area.

4 . The burn assessment chart of claim 1 , the interactive surface is a screen of a tablet, smartphone, or laptop.

5 . The burn assessment chart of claim 1 , wherein the burn assessment chart is coupled to a web-based application generating a visual display, the visual display projecting the features of the burn assessment chart onto the interactive surface.

6 . A method of generating a burn assessment chart for determining a percentage of surface area of a burn patient that has been burned to identify treatment, the method comprising:

rendering a first profile comprising a head, two arms, a torso, and two legs corresponding to a front profile of human;

drafting a plurality of longitudinal lines within the first profile;

drafting a plurality of lateral lines intersecting the plurality of longitudinal lines within the first profile, to form a plurality of first segments, wherein each segment of the plurality of first segments correspond to a percentage of a total surface area of the front profile of a human;

rendering a second profile comprising a head, two arms, a torso, and two legs corresponding to a rear profile of the human;

drafting a plurality of longitudinal lines within the second profile; and

drafting a plurality of lateral lines intersecting the plurality of longitudinal lines within the second profile, to form a plurality of second segments, wherein each segment of the plurality of second segments corresponds to a percentage of a total surface area of the second profile of the human, wherein the plurality of first and second segments of the first and second profiles is equal to one hundred percent, further wherein, each of the first and second segments correspond to one percent of the of the total surface area of the first and second profiles, the first and second segments being selectable by a user, the selection corresponding to an observed burn of a burn patient.

7 . The method of generating a burn assessment chart of claim 6 , wherein the plurality of first segments comprises fifty segments having an equal surface area and the plurality of second segments comprising fifty segments having an equal surface area.

8 . The method of generating a burn assessment chart of claim 7 , the plurality of first and second segments being selectable based upon an interaction with a specific segment of the plurality of first and second segments, wherein each segment selected corresponds to an observed burn.

9 . The method of generating a burn assessment chart of claim 6 , the plurality of first segments comprising one-hundred segments having a variable surface area and the plurality of second segments comprising one-hundred segments having a variable surface area.

10 . The method of generating a burn assessment chart of claim 6 further comprising the steps of:

providing a processing device having a processor comprising data storage and memory, wherein the processor is configured to generate output based on secondary input;

providing a visual display, the visual display being coupled with the processor, the visual display projecting the features of the burn assessment chart;

providing a visual indicator on the visual display responsive to selection of first and second segments selected by the secondary input;

storing the first and second segments selected on the processing device; and

tabulating the total number of first and second segments selected.

11 . The method of generating a burn assessment chart of claim 10 further comprises the step of assigning a percentage of body surface area based upon the tabulation of a total number of first and second segments selected.

12 . The method of generating a burn assessment chart of claim 10 , wherein the secondary input comprises any one of a local input, a smart phone, a computer, a tablet, or a cloud storage.

13 . A burn assessment system for determining a percentage of surface area burned on a burn patient and identifying treatment, the burn assessment system comprising:

a digital body surface area chart comprising a first and a second profile corresponding to a front and back profile of a human, a plurality of longitudinal and lateral lines intersecting to create a plurality of first and second segments wherein each of the first and second segments corresponds to a percentage of a total surface area of the front and back profile, further wherein the first and second segments correspond to at one percent of the total surface area of the front and back profile;

a processing device having a processor wherein the processing device is configured to generate output based on inputs received from a secondary device; and

a display screen coupled to the processing device, the display screen comprising an interactive surface projecting the body surface area chart, wherein the interactive surface is configured to receive a plurality of segment selections corresponding to an observed burn area of the burn patient.

14 . The burn assessment system of claim 13 , wherein the secondary input comprises any one of a local input, a smart phone, a computer, a tablet, or a cloud storage.

15 . The burn assessment system of claim 13 , the plurality of first and second segments comprising one-hundred segments having an equal surface area.

16 . The burn assessment system of claim 13 , the plurality of first and second segments comprising one-hundred segments having a variable surface area.

17 . The burn assessment system of claim 13 , the plurality of first and second segments comprising two-hundred segments having an equal surface area.

18 . The burn assessment system of claim 13 , the plurality of first and second segments comprising two-hundred segments having a variable surface area.
