A Survey on Technologies Used in Glucose Monitoring for Diabetic Patients

In the recent years, there has been a great improvement of technology in engineering as well as medical industries. Even though the technology has increased in the medical field, the patient's waiting time in hospitals and emergency appointments is extremely costlier nowadays. In the modern lifestyle many people are susceptible to Diabetes Mellitus (DM).The management and monitoring of DM is a challenge for the diabetic patients. This paper surveys about the various methods used in self-monitoring of blood glucose levels pervasively. The devices used for self-monitoring of glucose level are also discussed in this survey. These devices are very useful in the present busy life scenario. The major disadvantage of these devices is that they are expensive and cannot afford by all diabetic patients. An idea can proposed which involves the preparation of the kit which directly calculates the glucose level and automates with an alert message that includes the diet control,exercise control and medication control.

Self-Monitoring of Blood Glucose with a Non-Invasive Method Using Near Infrared Sensor

SANITAS: Jurnal Teknologi dan Seni Kesehatan, 2020

Diabetes mellitus or commonly called diabetes is a worldwide epidemic caused by chronic hyperglycemia. Simplify the blood glucose monitoring and easy to use is an essential part of diabetes management. Currently, the use of blood glucose meters conventional in clinical practice needs sufficient reliability. Therefore, self-monitoring of blood glucose with a non-invasive method was presented. A non-invasive blood glucose monitoring device was initially for information on glucose level measurements. A non-invasive method to determine the level of glucose by applying the physical properties of the absorption of the laser sensor that can produce a voltage change at various glucose levels. In this paper, a glucose monitoring module was fabricated with dimensions of 25x27x15 cm which has a minimum system, sensor, and LCD as a display of glucose levels. A minimum system to control the output of data digital value using microcontroller Android nano v.3. Experimentally, testing this module i...

Non-Invasive Glucose Estimation Using IR Spectroscopy

Diabetes milletus is disquieting human lives. The key health issues such as cardiovascular diseases, damage of blood vessels, stroke, blindness, chronic kidney damage, nervous system diseases, amputation of foot due to ulceration and early deaths are caused by poor management of diabetes. The reason behind all these are negligence in continuous monitoring. Regular monitoring of blood glucose is important to avoid complication of diabetes. Commonly used glucose measurement means are offensive which generally involves finger puncturing. These methods are painful and frequent pricking cause lumps on the skin and have risk of spreading infectious diseases. Therefore there is need to develop a non-invasive nursing system which can measure blood glucose continuously without much problem. The present work is focused on evolution of non-invasive blood glucose measurement sensor system using Near-infrared technique. Later a Sensor patch was designed using LED and a photo diode to observe diffused reflectance spectra of blood from the human forearm. Diffused reflectance spectra of the patients obtained with this technique was also compared with commercially available invasive glucose-meter. The results are hopeful and show the potential of using NIR for glucose measurement.we use sensor to monitor the blood glucose level of the patient. When it is High Level Glucose, Insulin will be injected through a syringe from Servo Motor Side. High rise of glucose level may lead to heart attack or any difficulty situations so we use via SMAC-Server Updating the patient Condition easily for identification in the PC Unit. In case of any abnormal situation we use motor to automatically inject the medicine into the patient using the syringe.

AN EMBEDDED SYSTEM FOR NON-INVASIVE BLOOD GLUCOSE MEASUREMENT IN GLUCOSE TOLERANCE TEST

Diabetic patients need to monitor their blood glucose levels frequently to prevent complications related to the disease. Commonly used glucose measurement methods are invasive, uncomfortable, and usually require frequent finger pricking. This paper deals with the development of a non-invasive system for continuous measurement of blood glucose concentration levels, using near infrared light of suitable wavelength. Glucose determination using near infrared can be done by taking measurement of transmitted light through human body. This device may become very useful while conducting glucose tolerance test (GTT). In glucose tolerance test, patient should be given a measured dose of glucose solution to drink and blood is drawn at intervals of half an hour or one hour for two to four hours. This requires five to nine finger pricking for measurement of glucose concentration. By using this proposed device pricking can be reduced to one. First the glucose concentration is measured using conventional method for calibration. Then by comparing with the first sample measurement subsequent values can be determined without further pricking.

Noninvasive blood glucose monitoring system based on near-infrared method

International Journal of Electrical and Computer Engineering (IJECE), 2020

Diabetes is considered one of the life-threatening diseases in the world which need continuous monitoring to avoid the complication of diabetes. There is a need to develop a non-invasive monitoring system that avoids the risk of infection problems and pain caused by invasive monitoring techniques. This paper presents a method for developing a noninvasive technique to predict the blood glucose concentration (BCG) based on the Near-infrared (NIR) light sensor. A prototype is developed using a finger sensor based on LED of 940 nm wavelength to collect photoplethysmography (PPG) signal which is variable depending on the glucose concentration variance, a module circuit to preprocess PPG signals is realized, which includes an amplifier and analog filter circuits, an Arduino UNO is used to analog-to-digital conversion. A digital Butterworth filterer is used to remove PPG signal trends, then detect the PPG data peaks to determine the relationship between the PPG signal and (BCG) and use it as input parameters to build the calibration model based on linear regression. Experiments show that the Root Mean Squares Error (RMSE) of the prediction is between 8.264mg/dL and 13.166 mg/dL, the average of RMSE is about 10.44mg/dL with a correlation coefficient (R^2) of 0.839, it is observed that the prediction of glucose concentration is in the clinically acceptable region of the standard Clark Error Grid (CEG).

Infrared glucose portable device

2014

There are quite a few persons worldwide with severe issues to control the glucose level on its blood. Only in Mexico, there are about 10 million persons with this disease and well over 13 deaths in 100 in this country are due to diabetes. In order to help to control this health issue, we are proposing a device to measure in a swift, simple and efficient way abnormality glucose levels in blood by using infrared sensors. Glucose shows a high absorbance to infrared wavelength. By using such characteristic, it is possible to develop a mobile, low-cost electronic device capable to analyse a blood sample by measuring the absorbance in it. The process is performed by using an array of infrared diodes controlled by a low-power consumption microcontroller as well as by several algorithms within a case. A blood sample is put in a substrate within the case. Once analysed, the glucose level of such sample is analysed and displayed on a screen

GluMo: A Noninvasive Blood Glucose Monitor

2020

Diabetics are used to pricking their fingertips in order to check their glucose level. In an effort to sunset that practice, Santa Clara University’s Ethical, Pragmatic, and Intelligent Computing (EPIC) Laboratory has envisioned, designed, and prototyped a portable noninvasive glucose monitoring medical instrument which we have dubbed GluMo. In place of a drop of blood GluMo uses Infrared (IR) light emitters and receivers as part of a small form factor Internet of Things (IoT) medical instrument which calculates the amount of the IR wave’s interaction with glucose molecules within the blood stream. The information is then transmitted to a database for tracking, history building, and data visualization for the patient (and potentially the patient’s doctor if authorized). Since current single droplet blood glucose meters are attainable as cheap as 10 USD, in order to keep GluMo’s cost under 100 USD without diminishing the accuracy of the reading outside of an acceptable bounds, Near I...
