Abstract

A diabetic complications monitoring apparatus and a diabetic complications monitoring system using the same, includes a support fixture having a liquid crystal color changing sheet that is located on an upper surface of the support fixture and displays a foot heat distribution based on a color, a transparent glass that is located on an upper surface of the liquid crystal color changing sheet and comes into contact with user's feet to support the user's feet, a foot heat distribution measurement unit that includes a camera for imaging the liquid crystal color changing sheet and extracts and outputs a foot heat distribution from an image of the camera, a processor that acquires and outputs whether a disease occurs, or a position and size of occurrence of a disease, based on the foot heat distribution, and a data input/output device that audioizes and visualizes an output result of the processor.

First claim

The invention claimed is:

1. A diabetic complications monitoring apparatus comprising:
a support fixture having a plate shape;
a liquid crystal color changing sheet that is located on an upper surface of the support fixture and displays a foot heat distribution based on a color;
a transparent glass that is located on an upper surface of the liquid crystal color changing sheet and comes into contact with user's feet to support the user's feet;
a foot heat distribution measurement unit that includes a camera for imaging the liquid crystal color changing sheet and extracts and outputs a foot heat distribution from an image of the camera;
a processor that acquires and outputs whether a disease occurs, or a position and size of occurrence of a disease, based on the foot heat distribution;
a data input/output device that audioizes and visualizes an output result of the processor to guide the user or notify a preset external device; and
a light spectrum it at ed to a side surface of the transparent glass and configured to measure least one of a Raman and a near-infrared spectrum of the user's skin, wherein the light spectrum measurement unit comprises a light source that emits light through the transparent glass as a light transmission path toward the user's skin and a spectrometer that detects light absorbed, scattered, or reflected from the user's skin to obtain spectral data.

2. The diabetic complications monitoring apparatus of claim 1 , further comprising
a foot pressure distribution measurement unit that measures a foot pressure distribution of the user's feet using a pressure sensor array disposed between the liquid crystal color changing sheet and the support fixture, or between the transparent glass and the liquid crystal color changing sheet.

3. The diabetic complications monitoring apparatus of claim 1 , further comprising:
a weight change measurement unit that measures the user's weight using a weight measurement sensor attached to a lower portion of one of the liquid crystal color changing sheet and the support fixture and acquires and outputs a weight change pattern of the user.

4. The diabetic complications monitoring apparatus of claim 1 , wherein
the processor includes a disease prediction model obtained by previously learning a correlation between measurement information and disease information, and is configured to predict diabetic complications corresponding to at least one of a foot heat distribution, a foot pressure distribution, a weight change pattern, a Raman spectrum, and a near-infrared spectrum through the disease prediction model,
the measurement information includes at least one of the foot heat distribution, the foot pressure distribution, the weight change pattern, the Raman spectrum, and the near-infrared spectrum, and the disease information includes at least one of the diabetic complications and blood sugar.

5. A diabetic complications monitoring system comprising:
a patient monitoring apparatus that measures at least one of a foot heat distribution, a foot pressure distribution, a weight change pattern, a Raman spectrum, and a near-infrared spectrum of each patient and generates and outputs measurement information;
a patient information management device that acquires disease information of each patient and maps and stores the measurement information; and
a disease prediction server that generates a plurality of learning data in which a correlation between measurement information and disease information is defined based on information stored in the patient information management device, trains repetitively a disease prediction model, and acquires the disease information corresponding to new measurement information through the disease prediction model and provides the disease information when the patient monitoring apparatus transmits the new measurement information,
wherein the patient monitoring apparatus includes:
a support fixture having a plate shape;
a liquid crystal color changing sheet that is located on an upper surface of the support fixture and displays a foot heat distribution based on a color;
a transparent glass that is located on an upper surface of the liquid crystal color changing sheet and comes into contact with user's feet to support the user's feet;
a foot heat distribution measurement unit that includes for imaging the liquid crystal color changing sheet and extracts and outputs a foot heat distribution from an image of camera;
a foot pressure distribution measurement unit that measure distribution by using a pressure sensor array between the liquid crystal color charging sheet and the support fixture or between the transparent glass and the liquid crystal color changing sheet;
a light spectrum vent nit that is attached to a side surface of the transparent glass and measures at least one of a Re man spectrum and a near infrared spectrum for a user's skin;
a weight change measurement unit that measures and collects a user's weight by using a weight measurement sensor attached to a lower portion of one of the liquid crystal color changing sheet and the support fixture and acquires and outputs a weight change pattern, and
a processor that generates and outputs is measurement information including at least one of the foot heat distribution, the foot pressure distribution, the weight change pattern, the Raman spectrum, and the near-infrared spectrum, receives the disease information to audioize and visualize the disease information and outputs the audioized and visualized disease information,
wherein the light spectrum measurement unit is attached to a side surface of the transparent glass and configured to measure at least one of aspect a near-infrared spectrum of the user's skin, wherein the light spectrum measurement unit comprises a light source that emits light through the transparent glass as a light transmission path toward the user's skin and a spectrometer that detects light absorbed, scattered, or reflected from the user's skin to obtain spectral data.
