Description

TITLE OF INVENTION:

A SMART PATCH AND HEALTH ASSESSMENT SYSTEM

CROSS-REFERENCE TO RELATED APPLICATIONS AND PRIORITY

The present application claims priority from an Indian patent Application No: 202221008708, filed on 18^th February 2022, incorporated herein by a reference.

TECHNICAL FIELD

The present disclosure relates to a smart patch and a health assessment system more particularly, the present subject matter relates to a smart patch and health assessment system with image preprocessing and image analysis for assessing the health condition of the user.

BACKGROUND

Nowadays, because of increasing pressure on health care system of countries and scarcity of health care professionals in remote corners of world, tele-medicine has become an important way to fill the communication gap between the health care professionals and their clients. However, the major problem in tele-medicine is that clients or users may not be able to convey accurate/exact symptoms which may lead to wrong treatment and eventually to neglect or ignorance of proper medical care, resulting in chronic disease, thus adding to the overall disease burden. Moreover, if the diagnosis is not timely, it may adversely impact the overall cost of treatment as well as affect the course of the disease. Especially in countries like India, the overall economic burden of health care as well as lack of adequate and appropriate infrastructure makes treatment unaffordable and unreachable leading to delay in treatment and poor quality of advice. Another consideration is the scarcity of health care professionals, that adds to an over-burdened health care system. Therefore, there is a need for an affordable, user-friendly health assessment system which can be self-administered or is usable under minimum supervision and intervention. To further secure or aid accurate analyses, communication between a health care professional and a user may be attained on a digital platform that may be supplemented with sharing of assessed data in the form of audio or video data or visual images. Such data, particularly visual images may be easily shared by a user, remotely using the internet or using other means of data transfer such as pen drives and cards, with a health care professional. However, as captured images may be distorted or discoloured or a combination of both, it may lead to an erroneous prognosis of health or condition, adding to the complexity of such a system. Therefore, a system that is equipped to obtain guided images and/or pre-process the obtained images to thus provide highly reliable inputs to health care professionals is highly desirable. Thus, there is a long-felt need for a user-friendly diagnostic kit with a smart patch and a system which can diagnose or aid diagnosis by a health care professional, using image pre-processing techniques for streamlining the health care system and reduce the burden on health care professionals.
