简介: Over 30.3 million Americans currently have diabetes and a further 1.5 million are estimated to be diagnosed every year. Diabetes remains the 7th leading cause of death in the U.S. For diabetics, managing blood glucose levels is extremely important to maintain their health as high levels of glucose in the blood for extended periods can be fatal. Current glucose monitoring methods are very invasive and can the limit physical activities of users. This thesis investigated using a low power optical system to noninvasively read blood glucose levels to determine if this is a feasible method for glucose detection. A low power system is key in this design as it would allow for a smaller, portable unit that average diabetics could use daily. This thesis showed there was a correlation between the optical system and a standard glucose meter.

简介:世界上的糖尿病患者约占人口总数的8.5%,现已成为第八大主要致死原因。据世界卫生组织估算,糖尿病将在2030年升至第七位。这种增长趋势可从近年来的统计数据看出:糖尿病的死亡病例从2000年的100万增至2011年的140万。 控制糖尿病的一种主要方法是使血糖尽可能地保持正常水平。这导致对血糖仪的需求日益增加。 血糖仪是一种用于确定溶液中葡萄糖浓度的医疗设备。葡萄糖浓度的单位是毫克每分升(mg/dl)或毫摩尔每升(mmol/l)。血糖仪已成为糖尿病患者使用的家用血糖监测设备的重要组成部分。一天内可进行多次测量。 大多数血糖仪基于电化学技术。这些血糖仪采用电化学试纸进行测量。将一小滴待测溶液置于一次性试纸上,血糖仪将利用该试纸来测量葡萄糖。在葡萄糖的电化学测量中,最常用的两种方法是比色法和电流法。 在比色法中,LED或光传感器等构成模拟接口。跨阻放大器用于测量葡萄糖浓度。利用颜色反射率原理,根据光度测定法来确定试纸反应层的色彩强度。血糖仪生成葡萄糖浓度的测量值。 在电流法中,使用毛细管吸取试纸一端的溶液。此试纸还包含一个酶电极,其中含有葡萄糖氧化酶等试剂。葡萄糖在酶的作用下发生化学反应并在化学反应期间生成电子。随后测量流经电极的电荷,电荷量与溶液中的葡萄糖浓度成正比。此外,还会测量环境温度以补偿温度对反应速率的影响。大多数血糖仪采用此方法。图1给出了试纸的工作原理。

Non-invasive Blood Glucose Level Monitoring System for Diabetic Patients using Near-Infrared Spectro
标签:血糖
积分:1 类型:应用文档上传者:太白金星上传时间:2021-06-30
简介: This paper describes a non-invasive method for monitoring blood glucose levels of diabetic and non-diabetic peoples. A non-invasive method for glucose monitoring provides adequate control and greatly reduces the complications in diabetic patients; and consequently reduces the health care costs. Non-invasive method is advantageous as the possibilities of infections get reduced and even there is no pain of pricking the blood. The proposed method uses near infrared sensor for determination of blood glucose. Near-Infrared light is sent through the fingertip before and after blocking the blood flow. By analyzing the voltage variation received after transmission through fingertip, approximate glucose level is predicted. The obtained glucose level is further transmitted to the smart android app for further analysis and storage of the data.

积分:1 类型:应用文档上传者:太白金星上传时间:2021-06-30
简介:Wearable devices are receiving more and more attentions owing to their affordability, novel applications and convenient form factors. The market for wearable sensors is expected to grow at a Compound Annual Growth Rate (CAGR) of 19.15% from 2019 to 2025 to reach $31.96 billion by 2025. most wearable devices today only measure physical or electrophysiological parameters such as motion, pressure, temperature, ECG, or EEG [1]. While these parameters may be useful for monitoring general wellbeing and a few specific diseases, acquiring a more comprehensive picture of underlying physiology via additional wearable sensors will provide significant value to a much wider range of users. Nowadays, wearable devices that are embedded in textiles or directly mounted on the human skin are trending in the field. These improvements necessitate us moving forward to investigate flexible and light instrumentation circuits as well as energy sources. This thesis shows some of the efforts towards the next genera1 tion of these wearable devices. On the other hands, the battery life time of the wearable sensor device is of the tremendous importance.

First Clinical Experience with Retrospective Flash Glucose Monitoring (FGM) Analysis in South Africa
标签:血糖
积分:1 类型:应用文档上传者:太白金星上传时间:2021-06-30
简介: Background: In 2014, an innovative blinded continuous glucose monitoring system was introduced with automated ambulatory glucose profile (AGP) reporting. The clinical use and interpretation of this new technology has not previously been described. Therefore we wanted to understand its use in characterizing key factors related to glycemic control: glucose exposure, variability, and stability, and risk of hypoglycemia in clinical practice. Methods: Clinicians representing affiliated diabetes centers throughout South Africa were trained and subsequently were given flash glucose monitoring readers and 2-week glucose sensors to use at their discretion. After patient use, sensor data were collected and uploaded for AGP reporting. Results: Complete data (sensor AGP with corresponding clinical information) were obtained for 50 patients with type 1 (70%) and type 2 diabetes (30%), irrespective of therapy. Aggregated analysis of AGP data comparing patients with type 1 versus type 2 diabetes, revealed that despite similar HbA1c values between both groups (8.4 ± 2 vs 8.6 ± 1.7%, respectively), those with type 2 diabetes had lower mean glucose levels (9.2 ± 3 vs 10.3 mmol/l [166 ± 54 vs 185 mg/dl]) and lower indices of glucose variability (3.0 ± 1.5 vs 5.0 ± 1.9 mmol/l [54 ± 27 vs 90 ± 34.2 mg/dl]). This highlights key areas for future focus. Conclusions: Using AGP, the characteristics of glucose exposure, variability, stability, and hypoglycemia risk and occurrence were obtained within a short time and with minimal provider and patient input. In a survey at the time of the follow-up visit, clinicians indicated that aggregated AGP data analysis provided important new clinical information and insights

AN OPTICAL METHOD FOR MEASURING BLOOD GLUCOSE NON INVASIVELY
标签:血糖
积分:1 类型:应用文档上传者:太白金星上传时间:2021-06-30
简介: This paper investigates a possible method of measuring the Non Invasive Blood Glucose Concentration Level(NI-BGC), with the main objective of providing Preventive care against the onset of diabetes by frequent selfmonitoring. This paper rationalizes a method for NI-BGC through the use of Near Infrared Light (NIR) byemission from LASER and tries to find a relationship between absorbance of NIR by glucose. An apparatusbased on transilluminated LASER beam via the sensitive part of human finger is considered. This devicedepends upon atomic gas Helium-Neon (He-Ne) laser operating at a wavelength of 620-630 nm. Duringmeasurement the index finger is inserted into the sensing unit and the LASER light is passed through it, and thetransilluminated optical signal is detected by a photodiode and an equivalent electrical signal is obtained. Withthe help of look up table this electrical value is displayed in the form of direct blood sugar in mg/dL(milligram/deciliter).The result obtained shows a linear relationship of increase in glucose level as transmittedlight intensity level decreases.

简介: Over 17 million individuals in the United States are affected with diabetes. While incurable,diabetes is manageable with proper monitoring. Currently, monitoring is performed through useof stand-alone blood glucose meters that allows a diabetic to monitor blood sugar levels on aperiodic basis; the meter readings are either recorded into a log book or uploaded via proprietarysoftware to a desktop computer. The purpose of this senior design project was to offer a newapproach to patient self-monitoring through the development of a diabetes management systemusing the Handspring Visor Personal Digital Assistant (PDA). The design consists of aSpringboard module containing blood glucose metering hardware and an accompanying softwarepackage that operates the module and allows for the storage and processing of data. Thefollowing sections outline the process followed by the senior design group in their developmentof the design.
