Abstract

The present invention relates to a novel approach means of screening foot skin condition of patients at risk for foot tissue breakdown, such as persons with diabetes, through the provision of a remote screening device that can be used in telemedicine or home self-monitoring approaches. The invention would record high resolution images of the bottom of the patient's feet, without artifacts or other distortions that might arise from images taken of feet that have been compressed through standing and the like. These images could immediately be viewed by the patient and/or electronically submitted to a medical facility where clinicians could screen the images for signs of tissue breakdown.

First claim

What is claimed is:

1. A system for screening the skin condition of the plantar surface of the feet comprising:
a support frame having a front portion, a rear portion, a left portion, a right portion, a top portion, and a bottom portion;
a lower extremity support structure affixed to said support frame so as to extend upwardly from said top portion of said support frame; and
an image acquisition device interface affixed to said support frame, proximate to said rear portion of said support frame, said image acquisition device interface comprising retention framework for reception of, and stable retention of, an image acquisition device, said image acquisition device thereby being situated apart from said lower extremity support structure so as to acquire images without artifacts or other distortions.

2. The system for screening the skin condition of the plantar surface of the feet according to claim 1 , wherein said support frame further includes an elevation support framework for securely elevating said support frame substantially off a ground surface.

3. The system for screening the skin condition of the plantar surface of the feet according to claim 2 , wherein said elevation support framework for securely elevating said support frame substantially off a ground surface is selected from the group comprising either a static elevation stand or a foldable elevation stand.

4. The system for screening the skin condition of the plantar surface of the feet according to claim 3 , wherein said elevation support framework for securely elevating said support frame substantially off a ground surface comprises a foldable elevation stand, said foldable elevation stand being hingedly attached to said support frame at said front portion of said support frame.

5. The system for screening the skin condition of the plantar surface of the feet according to claim 4 , wherein said lower extremity support structure comprises two substantially parallel stabilizing leg cuffs.

6. The system for screening the skin condition of the plantar surface of the feet according to claim 5 , wherein said retention framework provides for reception of, and stable retention of, an image acquisition device and provides for the accommodation of said image acquisition device whereby said image acquisition device can be chosen from the group comprising cameras, video cameras, video/camera-enabled smart phones, video/camera-enabled PDAs, and video/camera enabled tablets.

7. The system fir screening the skin condition of the plantar surface of the feet to claim 6 , wherein said support frame is at least partially formed from at least one lightweight material that is chosen from the group comprising aluminum, titanium, fiberglass, or plastic.

8. The system for screening the skin condition of the plantar surface of the feet according to claim 7 , further including a source of directed illumination and a remote trigger for triggering said image acquisition device.

9. The system for screening the skin condition of the plantar surface of the feet according to claim 8 , further including a monitor interface electronically connected to said image acquisition device for real time viewing by an immediate user of images acquired by said image acquisition device.

10. The system for screening the skin condition of the plantar surface of the feet according to claim 8 , wherein said monitor interface is affixed to said support frame and extends therefrom in an outwardly projected fashion, and is electronically connected to said image acquisition device
for real time viewing by an immediate user of images acquired by said image acquisition device.
